Title: Manufacture of laminated wood
Inventor: SAKAI KENJI
IPC: B27N3/02
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To disperse overlaid parts of a small wood piece with another small wood piece freely and equally in a desired pattern by laminating intermediate raw materials of a standard projecting/recessed shape with the slid end edges, on the longer side of the small wood pieces. SOLUTION: Small wood pieces 11 out of the small wood pieces which constitute a small wood piece group 1a are made to slide in the fiber direction of the small wood pieces 11 along a first belt conveyor 2a by a tip deviating means on the way of conveying the small wood piece group 1a. Thus intermediate raw materials 1b of a standard projecting/recessed shape with the longitudinal end edges slid from each other of the small wood pieces, are obtained. Since a monolayer matlike laminate 4a by using the intermediate materials 1b is obtained, the adjacent small wood pieces 11 are always in a uniforme state. Consequently, it is possible to freely and equally scatter the overlaid parts of the small wood pieces 11 in a desired pattern. Therefore, the laminate wood with an almost uniform strength across the entire length can be efficiently obtained.

Title: Control device of variable capacity pump
Inventor: KAWABATA SACHIO
IPC: F04B49/00
Filed: 1990-10-04
Abstract: PURPOSE:To lessen the number of components used and simplify the configuration by conducting a pressure control and flow control through a set of solenoid- operated proportional decompression control valve and differential pressure type spool valve. CONSTITUTION:A controller 70 comprises No.1 adder/subtractor 71, which receives a pressure setting signal and a sensed pressure signal from pressure sensor 50 and emits their deviation epsilonP as output, and No.2 adder/subtractor 72 which receives a rate-of-flow setting signal and a sensed tilt angle signal from tilt angle sensor 60 and emits their deviation epsilonQ as output, and the controller emits selectively that epsilon of the deviations in which the tilt angle lessens. If epsilonP>epsilonQ after an oil-hydraulic pump 1 is started, the flow control is executed in priority, and a decompression control valve 20 is changed over to the supply position to cause decrease of the differential pressure  P, so that a spool valve 10 is changed over to the exhaust side to cause increase of the tilt angle, and thus the rate of discharge flow will increase. When thereafter the discharge pressure Pd increases to generate the condition epsilonP<epsilonQ, the deviation epsilonP is selected, and the pressure control is executed so that the discharge pressure becomes the set pressure value.

Abstract: PURPOSE:To prevent the telephone line from being connected from outdoor regardless of absence of a person and a telephone charge from being registered by switching the number of times of call signal detecting an incoming call depending on the judgement of the user. CONSTITUTION:A microcomputer 1 reads a key matrix section 13 soon after the reset at power application to recognize what number of times of call signals at the incoming detection is set. A number (N1-1) or (N2-1) is set to a register X. When a call signal comes, the ON and OFF time are measured and whether or not the time is within the standard is checked. When the time is at the outside of the standard, it is discriminated to be a noise and the signal is not recognized as the incoming call. When the measurement of the ON and OFF time is finished, a register Y is incremented by '1' and whether or not the content is coincident with the content of the register X set previously is checked. When coincident, after the ON time is measured once, and several tens of milliseconds are awaited so as to attains a sure OFF period, then the incoming call is detected.

Title: Disturbance preventing circuit for photoelectric switch
Inventor: MIYAUCHI TADANORI
IPC: H01H35/00
Filed: 1994-11-02
Abstract: PURPOSE: To make possible a stable operation with high sensitivity even against the incidence of disturbance light by providing a removing means for removing the DC component of a converted photoelectric current. CONSTITUTION: The anode and cathode of a photodiode D1 connected through a coupling capacitor C1 to an initial stage amplifier 21 are connected so as to be short-circuited by an inductance coil L1. Therefore, when the disturbance light of the DC component is made incident from sunlight or the headlight of a vehicle, the diode D1 generates the photoelectric current with photoelectromotive effect. Since most of this generated photoelectric current is the DC component, it is bypassed to the coil L1 and flows away, and there is no change between the anode and cathode of the diode D1. Thus, even when the disturbance light is made incident, saturation is prevented without being affected by it and no voltage is impressed to the diode D1, so that heat generation can be suppressed by the photoelectric current of the generated DC component.
