Title: Pressure sensor and its manufacture
Inventor: UKAI SEIICHI
IPC: G01L19/06
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To realize a pressure sensor whose pressure detecting sensitivity is not lowered and whose breakdown strength is high in the highly accurate sensor which comprises a polygonal center boss. SOLUTION: Piezoresistance elements 5a to 5d which are used to detect a stress, low-resistance layers 6a to 6d which are used to derive an interconnection and an interconnection part 7 which is composed of aluminum or the like are formed in advance on the surface of a semiconductor substrate 1. Normally, the thickness t1 of a diaphragm 2 is constant within the face of the diaphragm 2. Thick regions 4 in a thickness of t2 are formed near eight corner parts of an octagonal center boss 3. Since the thick parts 4 are formed only near the corner parts of the polygonal center boss 3, it is possible to realize a pressure sensor whose pressure detecting sensitivity is not lowered and whose breakdown strength is high.

Title: Ground line selection relay system
Inventor: EBIZAKA TOSHINOBU
IPC: H02H3/36
Filed: 1988-03-30
Abstract: PURPOSE:To prevent erroneous function due to voltage induced upon fault on a transmission line stringed together, by detecting the phase difference of zero-phase voltage between one and the other ends of the transmission line and locking the output from a ground line selection relay in case of anti-phase. CONSTITUTION:Upon occurrence of fault on a super high voltage system stringed together, zero-phase voltages VOA, VOB are induced in opposite phase at the opposite ends of circuits 21, 22 to be protected. A zero-phase voltage phase difference judging section 612 judges the opposite phase between the voltage VOA detected through a V0 detecting section 611 at one end and the voltage VOB at the other end fed from a zero-phase voltage detecting section 621 through an indication line 72, and a zero-phase voltage phase difference detector 61 produces an output. A ground line selection relay 51 also produces an output, but it is inhibited and the relay 51 is locked. Another ground line selection relay 52 is also locked similarly. The voltages VOA, VOB are brought into in-phase upon occurrence of fault on its own line, and inhibits 8, 9 produce outputs thus operating the relays 51, 52. By such arrangement, erroneous function in its own line due to voltage induced from a line stringed together can be prevented.
