Abstract: PURPOSE:To detect abnormality in a cooling of system of a main body tank at an early stage, by arranging pressure sensors at a plurality of places of cooling pipes in the main body tank, and monitoring and measuring the pressure of refrigerant all the time or as required. CONSTITUTION:In a main body tank 1, a plurality of winding cooling ducts 9 are provided. In the Figure, a high voltage coil 9A and a low voltage coil 9B are shown. A plurality of iron-core cooling panels 10 are also provided, but one panel is shown. Liquid guide pipes for feeding the refrigerant are also separately shown as 13A for the windings and 13b for the iron cores. Since the potentials of the winding cooling ducts 9A and 9B are the same as the potential of the coils, the ducts are insulated from the liquid guide pipe 13A at the ground potential. Pressure sensors 16a, 16b, 16c, 16d, 16e and 16f are attached to branched pipe parts at the grounding potential. When abnormality takes place in the cooling system of the cooling duct 9A for the high voltage coil, the pressure at either 16a or 16b is fluctuated and externally measured.

Title: Exhaust gas flow control valve for internal combustion engine
Inventor: KURAMOTO AKIO
IPC: F02M31/083
Filed: 1978-05-12
Abstract: PURPOSE: To enable prevention for leakage of exhaust gas and intrusion of open air by tightly fitting a hollow collar to a valve shaft for an exhaust gas flow control valve and pressing against a contact surface of an exhaust gas path housing.  
     CONSTITUTION: A clearance of about 0.15 W 0.3 mm is existing between bushes 11, 12 and a valve shaft 13, therefore, exhaust gas in an exhaust gas path 6 intrudes into a space between the bush 11 and a blank cap 19 through this clearance. However, a hole 9 is perfectly shielded from open air by the blank cap 19, accordingly, exhaust gas never leaks to outside. Exhaust gas intrudes into a space between the bush 12 and a collar 20 through a clearance between the bush 12 and the valve shaft 13, however, exhaust gas will never leak to the outside because the collar 20 is fit to the valve shaft 13 tightly and furthermore the collar 20 is pressed against a flat outside surface of a housing 7 by resilient force of a compression spring 21.

Title: System for transmitting raman of optical fiber after amplification
Inventor: NISHIMURA HIDEKAZU
IPC: H04B10/00
Filed: 1988-03-11
Abstract: PURPOSE:To improve the amplification degree of the title system so as to extend its transmissible distance and, at the same time, so as to extend the life and to improve the reliability and economic efficiency of the semiconductor optical amplifier element used for amplifying pump light by not only sending pump light to an optical fiber from a transmitting section, but also sending pump light of the same wavelength to the optical fiber from a receiving section. CONSTITUTION:A transmitting section 1 simultaneously sends signal light and pump light having a wavelength which is different from that of the signal light to a receiving section 2 through an optical fiber 3 and the receiving section 2 fetches the pump light arriving at the section 2 and sends the pump light to the transmitting side 1 through the optical fiber 3 after amplification. Since the pump light inputted to the optical fiber 3 from the section 2 is produced by amplifying the received pump light, the pump light changes as the pump light from the section 1 changes. Therefore, the pump light at the section 2 emits light during the period, during which the signal light emits light, as the pump light at the section 1 does. In other words, the pump light at the receiving section 2 emits light during the signal transmitting period only. Therefore, the life of the semiconductor optical amplifier element used for the amplification can be extended as compared with the case where the amplifying operation is continuously made and, as a result, the reliability and economic efficiency of the amplifier element can be improved.

Title: Control device for automatic transmission
Inventor: IWATSUKI KUNIHIRO
IPC: F16H59/08
Filed: 1990-03-07
Abstract: PURPOSE:To prevent shift shock to possible minimum by allowing alteration into the gear ratio, which is set for use in the specified conditions, only when the current operation is in the shift position which does not permit simultaneous shifting under the applicable running conditions. CONSTITUTION:An auto-transmission concerned is equipped with a torque converter 20, No.2 transmission part 40, and No.1 transmission part 60. Signals from a car speed sensor 102, throttle sensor 100, etc. reflecting the load condition of engine 1 are fed to a central processing unit (ECU) 104, which drives solenoid valves S1-S3 in a hydraulic control circuit 106 to perform shift control. Alteration into the gear ratio train to be adopted originally is permitted only when the shift position is such that no simultaneous shifting will take place in case the current shift position complies with the gear ratio train to be employed originally. This prevents occurrence of simultaneous shifting because of alteration of the specified conditions, which can prevent frequent generation of shift with large shock.
