Title: Method for controlling stepping motor and water heater
Inventor: KUWABARA HIROKAZU
IPC: F24H1/10
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To conduct a predetermined operation in a stepping motor in a short time by switching a speed reference signal to be given to define a rotating speed of the motor to the motor used as a drive source of a valve device according to an object for operating the motor. SOLUTION: A motor controller 63 of the stepping motor 61 receives a speed reference signal output from a control means 7 as a digital pulse signal and drives the motor by supplying a current to a stator of a pulse motor section 64 according to the received signal. The motor 61 is constituted to switch a pulse frequency of the signal according to an operating object of the motor 61. Thus, when a speed is required as compared with its torque in the case of driving the motor, a valve device can be rapidly driven.

Title: Mounting structure of noise filter
Inventor: INAO KIYOHARU
IPC: H02J3/01
Filed: 1991-12-13
Abstract: PURPOSE:To provide the stable noise reduction characteristic due to the change of element parameters and to simplify the design by selecting the main inductance so as to keep resonance frequency low as compared with the switching frequency. CONSTITUTION:With the fluctuation of a source impedance CS, the value of a main inductance L2 is decided based on a formula I so as to keep resonance frequency f1 lower than switching frequency fSW The resonance frequency f1 of the formula I is a resonance point frequency between the main inductance L2 and a source impedance CS. Therefore, the minimum value CS<min> at the fluctuation of the source impedance CS is used for the design. As a result, even though the source impedance CS is fluctuated, the noise reduction characteristic in the frequency band higher than the switching frequency fSW can be minimized.

Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce high-frequency currents and high-frequency voltages produced on the alternating-current input side of a direct-current power supply with low loss and enhance the efficiency of the power supply. SOLUTION: The direct-current power supply 4 extracts the fundamental frequency components of alternating-current input voltages VAC from an alternating-current generator 3 through a low-pass filter circuit 21 and inputs it to a multiplying circuit 24 together with a signal for the difference between the level of a direct-current output voltage VDC detected by an error amplifier 23 and the reference voltage VR of a reference power supply 22. Accordingly, oscillation of alternating-current input current IAC and alternating-current input voltage VAC produced due to delay in signal transmission in a control system is reduced, and high-frequency currents IN and high-frequency voltages VN produced on the alternating-current input side are reduced.  For the reason a damper circuit or the like involving power loss becomes urneccesary and high-frequency currents IN and high-frequency voltages VN produced on the alternating-current input side are reduced with low loss, efficiency being enhanced.

Title: Substrate conveying device
Inventor: MITSUYOSHI ICHIRO
IPC: H01L21/68
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a compact substrate conveying device with high reliability of supporting a substrate and hardly generating cross contamination. SOLUTION: Substrate guides 258a are provided higher than substrate guides 258b and on the outside in relation to the substrate center CW. At the time of conveying an untreated substrate W, hand elements 253a, 253b are closed. The substrate guides 258a therefore come in contact with the substrate W to support it. At the time of conveying the substrate W finished with treatment, the hand elements 253a, 253b are opened. The substrate guides 258b therefore come in contact with the substrate W to support it. Cross contamination is therefore suppressed, and since the hand elements 253a, 253b are opened/closed only in a nearly horizontal direction, the substrate W hardly falls even in the case of air bleed being generated to an air cylinder for driving these hand elements.
