Title: Semiconductor acceleration sensor and manufacture of the same
Inventor: AKAI SUMIO
IPC: G01P15/08
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain the air damping effect by air and to prevent the impairing of yield in accompany with the damping by forming an air hole communicating the inside surrounded by a bonding layer with the external on one of the bonding layer and a stopper. SOLUTION: The main surface side of a single crystal silicon substrate 10 is flattened by spin coatingn an SOG film on the main surfaee side, and the clearance formed on a silicon nitride film on a diffused resistor wiring 15 is buried by the SOG film to flatten a metallic layer for bonding 17, whereby the generation of clearance with respect to an upper stopper is prevented. A single air hole A communicating the inside surrounded by the metallic layer for bonding 17 with the outside, is formed on the metallic layer for bonding 17. Air is filled inside of a sensor tip through the air hole A, whereby the air damping effect can be obtained. In addition, since there is formed only one air hole A, the intrusion of water and chips through the air hole A during dicing can be prevented by the air pressure inside the sensor chip.

Title: Tap switching controller at alternating current and direct current conversion station
Inventor: UEDA HIROSHI
IPC: G05F1/14
Filed: 1981-09-17
Abstract: PURPOSE:To reduce DC transmitted electric power and to shorten the AC voltage drop time of a power inverter side, by performing extremely speedy tap switching when the AC bus voltage of a power rectifier side drops. CONSTITUTION:Voltage variation of an AC system is held within a certain range under AVR controls by each generator group and reactive power control at each substation. Its variation width is assumed to be + or -3%. Then, the voltage switching width of each tap of a switch 12 is assumed to be 1%. An AC bus voltage in an initial control state has +3% variation and a tap position is set to a tap 1. In this state, if the AC voltage of an AC bus 01 varies from a +3% state to a -3% state as maximum variation, a valve-side winding voltage has a 6% voltage drop in total. A tap group selection part 11 compares it with a reference valve-side winding voltage to detect whether the deviation is greater than a prescribed value or not, thereby sending a tap group selection signal to the tap switch 12. By this signal, a switch C is closed and a switch B is opened as shown in a figure (b) ; and then a switch A is opened as shown in a figure (c). Thus, the tap position is set to a tap 4 and the switching is completed.
