Title: Ignition control device for internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02D45/00
Filed: 1989-07-12
Abstract: PURPOSE:To have ignition at a certain ignition timing corresponding to dislocation of the sensed angle position given by a crank angle sensor from the actual value, by sensing this dislocation, and correcting the ignition timing of the basis of the dislocation. CONSTITUTION:The maximum intra-cylinder pressure sensed by an intra-cylinder pressure sensing means when fuel supply is stopped and the engine performs only pumping action, is generated at the compressive upper dead center. Thus the angle position corresponding to the compressive upper dead center at which the intra-cylindrical pressure maximizes, is sensed by an intra-cylinder pressure peak position sensing means, and the angle deviation of this angle position from the compressive upper dead center sensed by a crank angle sensing means is calculated by an angle deviation calculating means. Because this angle deviation corresponds to the sensing error of the crank angle sensing means, the ignition reference is corrected to the normal position if the ignition timing is corrected by an ignition timing correcting means on the basis of the abovementioned angle deviation, and ignition is performed at the desired ignition timing.

IPC: G01N19/08
Filed: 1988-07-18
Abstract: PURPOSE:To achieve a higher automation level of a machine having a weak pin by forming an empty chamber at a weak part of the weak pin. CONSTITUTION:A liquid supply system A comprises an air feeder 9, a labirynth device 7 and pipes 6 and 8 and a liquid pressure detector system B is made up of a pressure sensor 10, an alarm 12 and signal lines 11a and 11b. a downstream end of the supply system A communicates with an empty chamber 2 of a weak pin 1. When a pin 1 is normal, no leak is caused in a pressure air fed from the device 9 and hence, there is no drop in pressure with no flow of air via the device 7. An air pressure within a pipe 6 is kept at a level of air supplied from the device 9. In such a condition, a sensor 10 transmits a pressure data to the device 12, but no alarm is emitted as the air pressure is equal to that of the device 9. In case the weak pin 1 is broken, the pressure air in the empty chamber 2 is released into atmospheric air to lower the air pressure in the pipe 6 because of the existence of the device 7. Thus, likewise, a signal of the sensor 10 is compared with the air pressure of the device 9 to emit an alarm.

Title: Forming method of insulator isolating region of semiconductor device
Inventor: GOTO HIROSHI
IPC: H01L21/76
Filed: 1985-08-16
Abstract: PURPOSE:To obtain an insulator isolation region which has no crystal defect caused by a stress nor unpreferable recess by forming an oxide film, SiO2 film, due to thermal oxidation on the side of a groove, then directly nitriding the surface of the oxide film of the side of the groove before filling the groove with a polycrystalline silicon layer. CONSTITUTION:A U-shaped groove 22 is formed on a single crystal silicon substrate 21 in the same steps as the conventional steps, an SiO2 film 23b is then formed on the side of the groove 22 by thermal oxidation of silicon, the film 23b in the groove is directly thermally nitrided to form a thin nitride film 27. A polycrystalline silicon 28 is so formed on the entire surface as to bury the groove, and a polycrystalline silicon portion on an Si3N4 film 24 is removed by polishing to allow it to remain only in the groove. Then, the front surface of the layer 28 in the groove is thermally oxidized to form an SiO2 film 29, and the film 24 is then removed. Since the volume becomes approx. twice when the Si becomes SiO2 at the thermal oxidation time of the film 29, it presses the film 24 to coat the layer 27 to eliminate the etching of the nitride layer. Thus, an insulator isolation region of the groove is formed.
