Title: Shelf net loading structure of storage
Inventor: YAMAMOTO MASAYUKI
IPC: F25D25/02
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to expand a housing space to a maximum and support a storage article with stability by discharging favorably the drain water deposited on the bottom of a storage compartment. SOLUTION: The bottom 13 of a storage compartment 2 is formed on an inclined surface which slopes downwardly from the inner part toward the front side. There is provided a rubber-made support member 16. When a shelf net 5 is loaded immediately on the bottom 13 of the storage compartment 2, a support member 16 is respectively mounted on the end on the front side of an outer frame 6a on both sides. When the shelf net 5 is loaded on the bottom 13, it is supported in a horizontal posture which floats up only the edge on the front side. The water flowing down on the bottom 13 is smoothly drained without being stopped at the edges of the shelf net 5. Since only one edge side is lifted up, a dead space will be minimized, which makes it possible to take up a large housing space to that extent.  Since the shelf net 5 is supported in the horizontal posture, it is possible to prevent a storage article, which is loaded thereon, from falling down or rolling.

Title: Method for automatically deciding signal parameter of analog display signal received by display unit of computer system, and device therefor
Inventor: EGLIT ALEXANDER J
IPC: G09G5/10
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To make correctly decidable the display signal parameter of an analog display signal, by coding a test pattern in a form of analog signal frame and sending it. SOLUTION: A graphics controller 260 encodes a test pattern having a prescribed format in an analog signal. The graphics controller 260 sends an analog signal to a display unit 270. The graphics controller 260 gives an instruction that the transmitted analog signal includes a test pattern to the display unit 270. Then, the display unit 270 receives the coded digital signal, and by checking the test pattern, decides a display signal parameter. The display unit 270, when treating the succeeding received analog signals in forming display signals at the time of generating display signal, uses decided display signal parameter. The succeeding displays are based on the decided display signal parameter, so the image coded in the analog signals is displayed on the display screen correctly and regeneratively.

Title: Circuit breaker
Inventor: NISHINA KENICHI
IPC: H01H71/12
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal wear by opening a contact mechanism in a short time without malfunction by the use of the force of a blast, by providing a relay device for opening the contact mechanism and energizing an actuator thereof to actuate a release means when the pressure of the blast is higher than a fixed value. SOLUTION: An actuator 24 is energized at a fixed value by a compression spring 25a or an energizing member so as to close a blast hole 23. When the pressure of a blast exceeds the fixed value, the actuator 24 is turned to cause a trip operation, thereby opening a contact mechanism 4, and a fixed value of pressure is set up. In the case of a lower-current rated circuit breaker, a relay device 30 is used having a projection part 37a whose height is set lower in a case 37. This causes a spring holder 26 abutting on the projection part 37a to be shifted leftwards in the Figure, thus disposing the compression spring 25a in a state of lower load, Therefore, the actuator 24 closes the blast hole 23 by a smaller energizing force and is turned by a smaller blast pressure.
