Title: Article detecting system
Inventor: SATO SHINICHI
IPC: G06K7/016
Filed: 1989-10-16
Abstract: PURPOSE:To make it possible to detect an article even if a background level is sharply changed by sampling the background level by a 1st register and finding out a change for the sampled level by a 2nd register. CONSTITUTION:The background level is detected from the light receiving output of a light receiving part 2 and an article is detected by a difference between an article level and the background level. Thereby, plural registers 4a, 4b are prepared, the light receiving output is sampled while changing a sampling interval and the difference is calculated by a control part 5 to detect the article. Namely the register 4a samples the light receiving output at a slow period to detect the background level and the register 4b samples the output at a short period to detect a change in the background level so as to detect the article. Since the control part 5 compares the absolute value of the difference with a threshold, the noise component of the background level due to disturbance light can be cut out to detect the article. Thereby even if the background level is changed, the article can be accurately detected.

Title: Fuel injection engine
Inventor: SHIOBARA SHOICHI
IPC: F02D41/04
Filed: 1989-10-18
Abstract: PURPOSE:To highly accurately control a small injection amount without using a high accurate injection valve by changing an opening time of the injection valve in accordance with the injection amount, at the time of high and intermediate load operations, and opening the injection valve by a number of times smaller than that in a plurality of cycles at the time of low load operation. CONSTITUTION:At the time of high and intermediate load operations, since an injection amount is increased with also a long injection time width, injection valves 40a, 40b are enabled to follow-up open-close timing with injection performed intermittently one time or a plurality of times in the predetermined timing in one cycle of an engine 10. Further at the time of high speed high load operation, the respective injection amount is reduced with improvement contrived of fuel consumption. At the time of low load operation with a throttle valve opening in not more than a fixed value, since an injection time, determined by a control unit 62, is decreased, the injection valves 40a, 40b are disabled from responding to this short injection time. Then at the time of low load operation where the throttle valve opening is decreased to not more than the predetermined value, injection is performed by thinning its number of times without corresponding to 1 cycle of the engine 10 in a range from the predetermined speed lower than an idling speed to a high speed side.

Title: Electrodeposited grinding wheel
Inventor: HASEGAWA KIYOSHI
IPC: B24D3/14
Filed: 1990-10-05
Abstract: PURPOSE:To make the execution of an extremely precise machining process possible by forming a basic metal of high strength glass. CONSTITUTION:In a grinding wheel 1 made of super abrasive grain, such as cubic system boron nitride or diamond, electrodeposited on a disc-shaped basic metal 2, the basic metal 2 shall be formed of high strength glass. Since the high strength glass is brittle material, it is difficult to deform, and bears up against given external force up to an allowable stress value to keep the proper strength of the high strength glass for maintaining its original shape, but since, in the case of given external force exceeding a certain stress value, brittle fracture then occurs rapidly in the high strength glass, a high speed rotating body always suffering from stress such as the electrodeposited grinding wheel 1 prefers the brittle material, and the grinding accuracy of a ground workpiece can be more steadily obtained in the case of applying the brittle material to the grinding wheel.

Abstract: PURPOSE:To prevent damage resulting from overheat of an electric motor by integrating the temp. change amount based on a specified temp. characteristic, determining the current temp. of the electric motor which drives a pump, and controlling the electric motor according to the comparative judgement of this current temp obtained with the upper and lower limit values.

A means 3 stores in memory the temp. characteristic which relates specifically the load current with the temp. change amount corresponding to the heat emission amount per unit time generated by the load current. On the basis of the temp. characteristic a means 4 integrates the temp. change amount relative to the load current and the temp. of the motor 1 to serve determining the current temp. of the motor 1. On the other hand, the current temp. of the motor 1 is compared with the preset upper limit temp. and lower limit temp. followed by judgement by a means 5. According to the result from judgement a means 6 makes control so as to rotate or stop the motor 1. This precludes damage due to overheat of the electric motor 1.
