Title: Differential pressure measuring device
Inventor: NISHIHARA TADASHI
IPC: G01L13/06
Filed: 1990-11-28
Abstract: PURPOSE:To enable damage of a liquid-isolating diaphragm to be detected easily by performing operation of a single of an electrostatic capacity electrode and that of a differential pressure sensor, a static pressure sensor, and a temperature detection sensor. CONSTITUTION:When a pressure from a high-pressure side is operated, pressure which operates on a liquid-isolating diaphragm 17 is transmitted to a silicon diaphragm 8 by an enclosed liquid 101. On the other hand, when pressure is operated from a low-pressure side, pressure which is operated on the liquid- isolating diaphragm 16 is transmitted to the diaphragm 8 through an enclosed liquid 102. Therefore, according to a pressure difference between the high- pressure side and the low-pressure side, the diaphragm 8 is distorted and an amount of distortion is taken out electrically by a strain gauge 9, thus enabling the differential pressure to be measured. Then, the electrostatic capacity electrode, the differential pressure sensor, the static-pressure detection sensor, and the temperature detection sensor are provided and operation is performed by a circuit which performs operation of signals of the differential pressure sensor, electrostatic detection sensor, and temperature detection sensor, thus enabling damage of the diaphragms 16 and 17 to be known.

Title: Manufacture of ceramic electronic parts and method for cutting ceramic block
Inventor: WATABE AKIO
IPC: H01G13/00
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent cutting in a slanting direction of a ceramic block. SOLUTION: A ceramic block 2 is cut by moving a cutting blade 1 vertically from one side to another of the ceramic block 2. The cutting blade 1 is stopped at least once during its travel between one side to another of the ceramic block 2. Since the ceramic block is not cut in one stroke but the cut blade 1 is stopped during its travel, the stress produced by the travel of the cutting blade 1 is released at each stop and the direction of travel of the cut blade remains unchanged. This prevents cutting in a slanting direction of the block.

Title: Cmis-type integrated circuit device and its manufacture
Inventor: KITA AKIO
IPC: H01L21/8238
Filed: 1994-12-28
Abstract: PURPOSE: To improve cut-off characteristics and to simultaneously achieve a high-speed operation and a low power consumption by further connecting a PMOS with a large threshold voltage to a logic circuit consisting of an NMOS and PMOSs. CONSTITUTION: In an active mode, a PMOS 3 is turned on by setting a control signal SLP to 'L'. At this time, a logic circuit consisting of an NMOS 1 and a PMOS 2 performs an inverter operation. Then, when an input signal IN is 'H', the NMOS 1 is turned off and the PMOS 2 is tuned off and then an output signal OUT goes to the level 'L'. When the input signal IN is 'L', the NMOS 1 is turned off and the PMO 2 is turned on and the level of the output signal-out becomes 'H'. Also, when the input signal-in is 'H', the PMOS 3 is turned off and current to a logic circuit is shut off by setting a control signal LSP to 'H'. At this time, the gate length of the PMOS 3 is formed to be longer than that of the PMOS 2 to increase a threshold voltage, thus improving cut-off characteristics.
