Title: Drive unit for stepping motor
Inventor: WAKABAYASHI SHINJI
IPC: H02P8/00
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to carry out adjustable-speed control without increasing the burden of treatment at control side by changing the rotation gently during ordinary forward and reverse rotations by revising excitation pattern to be used for power application to each phase of a stepping motor. SOLUTION: When control data transmitted from engine control ECU2 has changed from retention to open valve or from open valve to retention, a stepping motor 1b is rotated by 0.5 step in open valve direction; when a change occurs from retention to close valve or from close valve to retention, the stepping motor 1b is rotated by 0.5 step in close valve direction. When the control data are continuously open valve or already in open valve, the stepping motor 1b is rotated in 1 step unit for open valve or in open valve direction; if continuous retention occurs, the stepping motor 1b is stopped at that position. Thus, the stepping motor can be speed-adjusted adequately and step-out can be prevented.

Title: Hot water feeder
Inventor: OZAKI YUKINORI
IPC: F24H1/10
Filed: 1982-05-20
Abstract: PURPOSE:To reduce registance against the flow of mixed water in a mixing section by a method wherein a flow rate detecting means having the function of agitating the mixed water is provided between a mixing valve and a temperature detecting means arranged on the downstream side of the valve in the hot water feeder which is adopted to feed hot water by mixing high temperature water and ordinary temperature water to a desired set temperature. CONSTITUTION:When a faucet 109 is opened after setting the required temperature by a setting knob, an impeller 13 having a magnet 112 fixed thereto begins to rotate and the rotation of the impeller is detected by a magnetic detecting element 114. At the same time, a burner 117 begins to burn and the high temperature water from a hot water pipe 106 and the ordinary temperature water from a feed water pipe 103 flow into the mixing valve 105 so that both waters are mixed and supplied. When the mixed water flows out from the mixing valve and passes an impeller type flow rate switch 111, it is further mixed uniformly by the rotation of the impeller 113. When the mixed water is supplied, the temperature sensor 110 detects the temperature of the mixed water at all times and when the temperature of the mixed water is lower than the value value set by the setting knob, a motor 107 is operated so as to increase the flow rate ratio of the hot water temperature flowing into the mixing valve 105 from a hot water pipe 116, to thereby increase the temperature of the mixed water. On the other hand, when the condition is reversed, the motor 107 is operated so as to reduce the flow rate ratio of the high temperature water to the mixing valve 105 from the pipe 116, to thereby lower the temperature of the mixed water to be supplied and as a result, the mixed water is always supplied at a desired temperature.

Title: Controller for automatic dispenser motor
Inventor: MINAKANE KEIICHI
IPC: H01H21/36
Filed: 1990-03-30
Abstract: PURPOSE:To repeatedly execute the intermittent operation of a motor even if there is a backlash in a mechanical system by permitting a switch to turn off conduction to the motor after prescribed delay time from when it detects the stop position of a cam. CONSTITUTION:When a control part 5 detects a discharge signal S, conduction to the motor 3 is started. When the cam switch 7 detects the protruding part of the cam 6, the control part 5 operates a delay part 10. When the delay part 10 detects that the set delay time elapses, conduction to the motor 3 is immediately terminated and a driven shaft 2 is intermittently driven by a prescribed angle. Since the cam switch 7 considerably runs onto the protruding part 9 of the cam 6 and it terminates conduction to the motor with such constitution, the motor stops in the state where the stop position is securely maintained even if there is the backlash in the mechanical system and the driven shaft 2 is reversed. Consequently, normal intermittent driving can repeatedly be executed.

Title: Optical defect inspecting and correcting device
Inventor: SASAKI KENJI
IPC: G03F1/72
Filed: 1989-04-07
Abstract: PURPOSE:To perform correction during inspection and to shorten the correction time by uniting an inspecting device and a correcting device together. CONSTITUTION:The inspecting device and correcting device are united together. The laser light oscillated by a laser oscillator 1 is reflected by a mirror 4 to irradiate a body (a) to be inspected on a moving table 5, reflected and scattered at an inspection position on the body (a) to be inspected, and converged by a condenser lens, and a pinhole 7 cuts off reflected and scattered light except from the inspection position. The reflected and scattered light which is passed through the pinhole 7 is received by a photodetector, which sends the output of this photodetection result to a threshold circuit 10. At this time, if there is a foreign body present on the body (a) to be inspected, the reflected and scattered light which is received by the photodetector increases and when the detection output exceeds a threshold value set in the threshold circuit 10, the threshold circuit 10 sends a command signal for the output amplification of the laser light to a laser oscillator driving control circuit 17. Thus, the inspection is performed even during the correction, so the time can be shortened.
