Patent JP-S5886804-A (JP)
Title: Controller for electric rolling stock
Inventor: NODA TOMOHITO
IPC: B60L9/14
Filed: 1981-11-16
Abstract: PURPOSE:To remove unnecessary notch-off operation, while make starting acceleration approximately constant regardless of a contact wire voltage section by changing the position of stoppage of a cam shaft in response to contact wire voltage. CONSTITUTION:When a voltage converting shaft is normally positioned at a '600V' location, a relay 600R is at ON because an auxiliary cam contactor VC1 in a TX line is at ON. Accordingly, a current-limit value stage advancing command CLA is emitted in the cource of 600RC1 KMR2 L1C L2C RE, and a cam shaft begins to be turned in the direction of P1-P2 positions. The cam shaft is stopped at the P2 position because the auxiliary cam contactor KMR2 is at OFF at the slightly short position of the P2 position. When contact wire voltage is 1,500V the current-limit value stage advancing command is not emitted because the relay 600R is at OFF, and the cam shaft is left as it is stopped at the P1 position.

Abstract: PROBLEM TO BE SOLVED: To improve the oxidation resistance of a Cr-base superalloy of low Cr content by exposing a member for high temp. use to a high temp. atmosphere of low partial pressure of oxygen before use, particularly in a heat treatment process. SOLUTION: Gas turbine parts (stationary blade, moving blade, shroud), composed of a low-Cr Ni-base superalloy having region of [at.% Al]>=10 and [at.% Al]>=30-4.7 [at.% Cr], are treated before use, in the heat treatment process at >=900 deg.C, preferably 1000 to 1200 deg.C, at <=10 atm partial pressure of oxygen. Further, the control of the partial pressure of oxygen is performed by using a CO/CO2 or H2 /H2 O gaseous mixture and regulating the mixing ratio to about >=1/50 in the case of CO/CO2 gaseous mixture and to about >=100 in the case of H2 /H2 O gaseous mixture. By this method, the occurrence of oxidation in the part, among the parts having the fear of oxidation, incapable of coating can be inhibited.

Title: Pulse motor
Inventor: NIKAIDOU MITSUHIRO
IPC: H02K37/06
Filed: 1983-09-30
Abstract: PURPOSE:To improve the torque characteristics of a pulse motor by displacing halves of salient pole group of a stator to cancel the detent torque to the remaining salient-pole group. CONSTITUTION:A phase displacement of not P/2 but P/2+P/8 is provided between the opposed salient poles of magnetic units 10a, 10b (e.g., salient poles 11a1 and 11b1) between the teeths. In other words, the salient pole group of the unit 10b is displaced excessively in P/8 with respect to the salient pole group of the unit 10a. The phase displacement of P/8 corresponds to the inversion of the characteristic curve of the detent torque in a 4-mode pulse motor, and the detent torque in the entire pulse motor becomes the sum of the detent torques. Accordingly, they cancel each other and become almost zero. Thus, torque characteristic is improved, thereby obtaining smooth rotation.
