A limit switch box is used for an indicator of a valve actuator. This device indicates an opening and closing of a valve or a throttle in the valve actuator. In a ship, equipments require safety and robustness because of a rough environment and a specific condition during a voyage. However, the limit switch box has been used in an indoor environment generally. This study developed a new limit switch box which can be used at an outdoor environment. This study designed the new limit switch box. The housing of the limit switch box was made by an aluminum die cast method with surface painting after anodizing or chromate coating. In order to evaluate the endurance of the housing, the endurance tests against salt water have been conducted. Experiment results showed that the proposed device provides a reliable performance against salt water.

However, the limit switch box is used in an indoor environment generally. In order to evaluate the endurance of the limit switch box used in an indoor environment, the endurance tests against salt water have been conducted. Experiment results showed that the limit switch box was corroded severely. Thus, this study developed a new limit switch box which can be used at an outdoor environment. The housing of the developed limit switch box was made by an stainless steel to prevent corrosion.

This paper proposes an efficient switch-box router which consists of two parts ; greedy poly-jog router and via minimizer. The greedy switch-box router of Luk, routes not only metal wires at horizontal tracks and poly-silicon wires at vertical tracks but also poly-siliocon wires ar horizontal tracks if necessary. The via minimizer reduces the number of vias and the wire length by fipping of each corner, parallel moving of wire segment, transformation metal into poly-silicon, and transformation poly-silicon into metal. The result is generated through the column-wise scan across the routing region. The expected time complexity is O(M(Nnet)). Where M, N, and Nnet are respectively the number of columns, rows, and nets in the routing region.

Switch box is metal box and used for electric wire pipe in building. In manufacturing switch box, we need 5∼6 press machines, 5∼6 dies, 1 tapping machine. and 7∼8 operators. What matters is rise of manufacturing cost and operators' reluctance of working. To solve this problem, we modified the pre-existing die and developed handling mechanism, which leads to improve the manufacturing process. After the research and development, we could reduce the number of machines and workers needed in the process; 2 press machines, 2 dies, 1 tapping machine, and 1 operator. That means we can save labor and the number of operators needed, reduce manufacturing cost, and get the effect of import replacement.

A $\kappa$-side switch box with W terminals on each side is said to be hyper universal, denoted by ($\kappa$, W)-HUSB, if it is routable for any global .outing with density at most W. In [5], we have proposed a switch box design strategy and designed a near optimum (4, W)-HUSB F(W) with 6.W switches. In this paper, we design, analyze and implement an efficient detailed routing algorithm for the S-box F(W). This router. can accommodate all routing requirement topologies.

This paper presents a design of the enable switch circuit, which is consist of discrete device at smart junction box(SJB) board. The Enable switch circuit, which receives ignition signal (IG) for input, sends a drive signal to linear regulator and other elements. The circuit design is carried out in a BCDMOS $0.18{\mu}m$ technology, and the performances are verified through simulations according to AEC-Q100 and ISO 7637-2. Die area of the designed Enable switch circuit is $1.67mm{\times}0.54mm$ in layout, and it is shown that the die can be housed in $3mm{\times}3mm$ HVSON8 package. The designed enable switch circuit is expected to be widely adopted in various automotive SJB's since it can significantly reduce the overall printed circuit board form factor.

In this paper, a device for safety inspection of a guard lamp with an automatic switch which has been recently employed in some local autonomous entities was developed. It is technically enhanced by installing a separate inspection box down below, which allows the inspectors can measure the leakage current, the sound function of the electric leakage breaker(ELB), the insulation resistance and the grounding resistance, on the ground. This inspection box makes the inspectors free from the electric shock by being designed to minimize the potential direct contact with the energized terminals. The deliverables of this paper are expected to contribute to carry out the inspection for the guard lamps safely and effectively.

An instrumentation system to measure the pressure between elastic bodies and between an elastic and a rigid body has been developed. The force between elastic bodies can be measured only by Elastric- body pressure Meter. As a standard Elastic-body pressure Meter, Model RCG-24A consists of 24 pick-ups, one switch box and one amplifier and measuring is possible at each of 24 measuring spots by swithing one to the nest using the switch box. The system can be used in various specialized disciplines, such as ergonomics, anthropometry and biomechanics.

The gene aeg-46.5, which is expressed under anaerobic condition, has putative triple -10 regions and four transcription start sites. The mRNA transcription level and its start point change depending on the aerobic/anaerobic growth condition. RNA polymerase and its regulatory proteins must choose which of three -10 region to use. The putative triple 10 region was mutated to make only one of them function with consensus -10 region sequence (TATAAT) and the other two as non-functional region. The results show that the second and third -10 regions are used for the aerobic/anaerobic expression. The third -10 region is responsible for the high aerobic to anaerobic switch ratio. This suggests that only the last two of the putative triple -10 region have functions on aeg-46.5 gene expression switch control. The phenotype of the mutated promoter was tested in the wild type cell and narL - cell. The results indicate that the control by NarL is independent from the selection of -10 region. The expression patterns on multi-copy plasmids and on single-copy chromosome were compared. These results show that the aerobic/anaerobic switch control of aeg-46.5 is through the choice of -10 region. The mechanism of choosing different -10 region remains to be seen.
