Patent JP-H1038731-A (JP)
Title: Semiconductor pressure detector
Inventor: MAKI KAZUO
IPC: H01L29/84
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To enhance the linearity of pressure-electric output without sacrifice of measurement accuracy even at the time of low pressure measurement by making a groove in the periphery of the strain generating part at the fixed part of a diaphragm. SOLUTION: A thin strain generating part 1a and a thick fixed part 1b surrounding the strain generating part 1a are formed on a diaphragm 1 made of silicon single crystal. A groove part 6 is made around each side of the strain generating part 1a by etching. Even when a pressure is applied to the strain generating part 1a which is thereby flexed significantly, membrane force is lessened at the strain generating part 1a because the strain generating part 1a is in a state approximate to free support with respect to the fixed part 1b. Consequently, a semiconductor pressure detector excellent in the linearity of pressure-electric output can be obtained without forming a thick strain generating part 1a. Since a thick strain generating part 1a is not required, pressure can be detected without lowering the sensitivity.

IPC: H04M3/08
Filed: 1985-09-09
Abstract: PURPOSE:To detect a fault without provision of a new circuit by using a control section of a subscriber circuit to analyze added information from a call signal output device.

Title: Device for controlling steam turbine
Inventor: ODAWARA MASACHIKA
IPC: F01D17/20
Filed: 1986-08-26
Abstract: PURPOSE:To prevent a sudden rise of the turbine revolving speed by setting the initial valve-opening of a steam governor in correspondence to a delay time striking of the system-starting-signal to a start of speed-rising of a turbine. CONSTITUTION:An electrically operated valve 41 is provided at the upstream side of a steam governor 45 and of a steam stop valve 43 of a turbine 83. Signals b and i from a position detector 47 and from a revolving speed detector 69 of the electrically operated valve 41 are input to a valve opening signal computing element 49. Based on both turbine starting signal b and actual turbine speed signal i, the computing element 49 measures a delay time from the striking of an RCIC starting signal a to a start of speed rising of the turbine 83. In addition, from the relation between the delay time stored in advance and the initial valve-opening-set-value, the element 49 selects the initial valve-opening of the steam governor 45. With this contrivance, when the delay time becomes long because of insufficient warming-up, the initial opening of the governor 45 can be made smaller, thereby lowering the initial, peak revolving-speed of the turbine 83.
