Title: Control device for engine
Inventor: MAKIMOTO SEIJI
IPC: F02P5/15
Filed: 1987-03-31
Abstract: PURPOSE:To hold a good combustion condition even in the time of transient operation in which an engine operative condition rapidly changes, by providing an ignition timing correcting means which operates when the actual amount of lubricating oil for cooling deviates from a preset value. CONSTITUTION:When cooling oil, for suppressing knocking, is unable to follow up corresponding to the operative condition of an engine because it is rapidly accelerated, an engine control unit 13 operates as follows. That is, an ignition timing correcting means 38, being based on the decision by an acceleration decision means 36 and an oil pressure sensing decision means 37, corrects the ignition timing to a retard side actuating an ignition device 12 by an output from a final ignition timing arithmetic means 39 when a deviation of the actual oil pressure from the preset value by a high pressure control is larger Than the predetermined value in the time of transient operation in which the engine is accelerated in a region of low pressure control being transferred to a region of high pressure control. In this way, supplementing cooling insufficiency during the time till the oil pressure rises after the engine is accelerated, the engine, suppressing the generation of knocking, holds a good combustion condition.

Title: Liquid level detecting device
Inventor: NAGASHIMA HIROSHI
IPC: G01F23/30
Filed: 1983-05-09
Abstract: PURPOSE:To improve vibration resistance, detecting accuracy, life and explosion proof, by the constitution, wherein a float is inclined up and down with the increase and decrease in liquid level, a movable reflector is moved in the approaching direction or separating direction, and light from a light emitting element is made to transmit or not to transmit to a light receiving element. CONSTITUTION:When a liquid level reaches a specified upper limit, float 1 is inclined upward. A movable reflector 4 in a guide 3 is slidden to the approaching direction toward a light emitting element 5a and a light emitting element 5b by the action of gravity. Therefore the light from the light emitting element 5a is reflected by a reflecting surface 4m to a light receiving element 5b. The light is received by the light receiving element 5b, and reaching of the liquid level to a specified upper limit can be electrically detected. When the liquid level reaches a specified lower limit, the float 1 is inclined downward, and the movable reflector 4 in the guide 3 is slidden in the separating direction from the light emitting and receiving elements 5a and 5b. Therefore the light from the light emitting element 5a to the light receiving element 5b is attenuated. Based on the attenuating state, reaching of the liquid level to the specified lower limit can be electrically detected.

Abstract: PURPOSE:To simplify steps by forming a compound semiconductor crystal containing mercury on a substrate formed with recesses, polishing it, then adhering an infrared ray permeable substrate on the surface of the crystal, then removing the rear surface side of the substrate until the crystal is exposed to form an insular region of the crystal, and implanting impurity to form a P-N junction. CONSTITUTION:After a compound semiconductor crystal 14 containing mercury is formed on a compound semiconductor substrate 1 with recesses 13, the surface of the crystal 14 is polished, and an infrared ray permeable substrate 16 is adhered to the surface of the crystal 14. Then, the rear surface side of the substrate 11 is removed until the crystal 14 is exposed to form an insular region of the crystal 14 surrounded by the substrate 11, impurity atoms are implanted to the crystal 14 to form a P-N junction 17 in the crystal 14. The photoelectrically transduced carrier is not stopped from becoming leakage current at a boundary position between Hg1-xCdxTe crystal 14 and CdTe substrate 11 to prevent a surface leakage current from generating. Thus, formation of an insulating film having complicated steps such as an anodified film, an anode sulfided film, etc., is omitted to obtain a detector having high sensitivity.
