Title: Peak detection circuit of three-phase current
Inventor: HARADA TAKASHI
IPC: G01R19/165
Filed: 1993-12-20
Abstract: PURPOSE:To accurately detect the peak value of three-phase AC current. CONSTITUTION:The output of U-phase and V-phase current sensors is subjected to half-wave rectification by a half-wave rectification circuit which is constituted of operational amplifiers OP1 and OP2. Further, the positive and negative side output of each rectification circuit is added and rectified by an addition rectification circuit constituted by an operational amplifier OP3 and the output corresponding to the current detection output of W phase is subjected to half-wave rectification. The half-wave rectification output is added by an adder constituted by an operational amplifier 0P4 and an output V<0> where the values obtained by performing half-wave rectification of the positive side of the three-phase current are added, is obtained. The output indicates the peak value of the three- phase current. Since operational amplifiers can be used, a voltage drop due to the internal elements of the circuit can be prevented by determining the constant of each circuit to, be a proper value, thus accurately detecting the maximum value of the threephase current.

Title: Injection molding die device
Inventor: AKIGUCHI TERUO
IPC: B29C45/26
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To easily form a through hole by moving forward a hydraulic ejector provided on an injection molding machine so that a sleeve with the tip part of a blade shape formed by tapering the internal periphery of the tip part penetrates an uncured material and the tip part is pressed against a cavity face on the fixed side. SOLUTION: When a second ejector plate 16 is pressed by a hydraulic ejector piston rod, a sleeve 26 is moved forward. Then when the tip of the sleeve 26 penetrates a molding to be pressed against a cavity face 1 on the fixed side, a fused material on the tip inner part of the sleeve 26 is pressed to the sleeve pin 27 side. Consequently, a spring 31 interposed between a piston 28 connected to the rear end of the sleeve 27 and a stopper member 30 is compressed, so that the sleeve pin 27 is moved backward and the fused material inside the sleeve 26 is stored. Thus a molding in the cavity 1 has a through hole.

Inventor: NISHIMURA MITSUO
IPC: H02N2/00
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to remove a bad influence due to the instability of the friction state of a sliding part, due to the fixation and the bonding of the sliding part and due to moisture by installing a moisture absorbing material inside a device casing which houses constituent members such as a vibrating body, a contact body and the like by which a vibration is excited by an electromechanical energy conversion. SOLUTION: In a vibration-type motor, a progressive vibration is excited in an elastic body 1 by a piezoelectric element 2, and progressive waves are generated on the surface of a slider material 3. A rotor 6 receives a frictional force whose direction is opposite to that of the progressive waves so as to be turned, and it is transmitted to the outside via a shaft 10. A driving part is housed at the inside of a base 5 and a casing 18. A ring-shaped moisture absorbing material 17 which is composed of calcium chloride or the like is installed on the inner wall of the casing 18 so as to absorb moisture in an assembling operation or moisture in a trace amount which flows into from a seal part. Thereby, the inside of the casing 18 can be set to a dry state, and it is possible to remove the influence of moisture on the friction state of the sliding face between a stator and the rotor 6.  Consequently, a driving device can be driven stably, and it is possible to prevent the driving device from being fixed and bonded.
