Title: Excitation controller for synchronous machine
Inventor: KORENAGA HITOSHI
IPC: H02P9/14
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To stably operate a synchronous machine even when system abnormality occurs by outputting a pulse, provided that the used voltage regulator is switched to an automatic voltage regulator from a manual voltage regulator, when the function of the manual regulator is restored and, while the pulse is outputted, by outputting a command which shifts the phase angle of a rectifier by a specific angle against the automatic voltage regulator to a phase control circuit. SOLUTION: When the function of a manual voltage regulator is restored, a single shot circuit 33 outputs a pulse to a transfer circuit 26, provided that the used voltage regulator is switched to an automatic voltage regulator 15 from the manual regulator. The circuit 26 outputs a command which shifts the phase angle of a rectifier 3 by 90 deg. from that of the regulator 15 to a phase control circuit 16. Therefore, a synchronous machine can be operated stably even when system abnormality occurs, because the manual voltage regulator is quickly switched to the automatic voltage regulator 15.

IPC: G08C19/00
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To reduce the leak amount of common mode voltage from the side of primary circuit to the side of secondary circuit by forming a center tap on the secondary winding wire side of a transformer for insulation and connecting this center tap to a ground on the side of secondary circuit. SOLUTION: A transformer 11 mutually insulates the primary circuit on the side of a primary winding wire 11a and the secondary circuit on the side of a secondary winding wire 11b and transmits a signal inputted to the primary winding wire 11a toward the secondary winding wire 11b.

The common mode voltage leaked to the side of the secondary winding wire 11c flows through the center tap 11d into the ground G2 of much lower impedance. In such a case, since the impedance of the center tap 11d is extremely low, no voltage is generated so that the common mode is not inputted to the resistor side as a result.

Title: Groove structure for wet type friction engaging element
Inventor: KAN SHIHOU
IPC: F16D69/00
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a groove structure which can enhance an engaging initial dynamic frictional coefficient by early braking an oil film interposed between a wet type friction engaging element and a mate member when the element is initially engaged. SOLUTION: In a groove 43 of a wet friction plate, a width direction sectional shape is formed almost in U shape in a friction material surface 42 of the wet friction plate 41 of a wet type friction engaging element, and width direction bottom part both angular parts 44, 44 of the groove are formed deeper than a width direction intermediate part. Since the bottom part both angular parts are formed deeper than the width direction intermediate part, in the groove, an oil pressure in angles (groove upper part angle) 45, 45 in the boundary between the friction material surface and the groove is generated lower than an oil pressure in a conventional angle of the groove, an oil film is early bursted, and an engaging initial dynamic friction coefficient of the wet type friction engaging element can be enhanced.  Since a width direction sectional area of the groove is a conventional width direction sectional area or less, necessity for increasing press work compression force, when forming the groove, is eliminated, and a work cost of the wet friction plate can be suppressed.
