Title: Method of injection molding cylindrical body and mold used therefor
Inventor: KURODA RIKIO
IPC: B29L23/00
Filed: 1994-03-07
Abstract: PURPOSE:To achieve the injection molding of a cylindrical body with excellent dimensional accuracy by injecting resin at a slant angle of a specific angle or more from the gate situated at one end of a cylindrical cavity to the longitudinal direction of a cylindrical cavity in the case of molding a cylindrical body through an injection molding of thermoplastic resin into the mold inner part defining the cylindrical cavity. CONSTITUTION:Upon molding a cylindrical body by injection molding thermoplastic resin into the mold inner part defining a cylindrical cavity 1, resin is injected at a slant angle of 5 deg. or more from the gate 2 situated at one end of the cylindrical cavity 1 to the longitudinal direction of the cylindrical cavity 1. The thermoplastic resin is selected from a thermotropic crystalline liquid resin or a composition containing the same, or a non-crystalline liquid thermoplastic resin composition consisting of a fiber or needle-like filler blended therein. As a result, a cylindrical body can be molded through infection with enhanced strength and rigidity and fine dimensional accuracy, and a cylindrical body is obtained with no likelihood of weld lines substantially and also no orientation of the mechanical strength such as longitudinal cracks or the like.

Title: Motor controller
Inventor: SEKIOKA KENICHI
IPC: H02P27/06
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent the oscillation in a power amplifier section when a low-impedance section is connected, by, when an anomaly detection signal is received, sending a switch signal to analog switches and relays to switch the analog switches and the relays simultaneously. SOLUTION: Power amplifiers 31, 32, an analog switch 34 and a power amplifier are combined as one set. The power amplifier section 3 of the motor controller is provided with the sets in the same number as the number of the current commands from a microprocessor 1. When the microprocessor 1 receivers a signal from an anomaly detector 7, the microprocessor 1 sends a switch signal to relays 4 and the analog switches 34. As a result, gain amplifiers 32 and the power amplifies 33 are connected with each other, and simultaneously the current from the power amplifiers 33 flowing to a motor 5 is forcedly bypassed to a low-impedance element section 6. Therefore, a trouble that a proper current control loop gain is maintained and further an excessive current flows to the motor 5 is prevented. As a result, the motor can be protected without causing oscillation in the current control loop.

Abstract: PURPOSE:To obtain a method of obtaining a similar result to a quantizing calculation at calculating time of the same degree as a classical calculation by applying a value proportional to a difference between the quantizing calculation result of an average depth of an inversion layer charge density and a classical calculation result to the thickness of an insulating film and a flat band voltage to obtain a similar result to the quantizing calculation.
