Title: Clutch operating cylinder device
Inventor: HATTORI YASUAKI
IPC: F16D25/08
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To reliably restore a clutch operating piston member even if the outer end of the clutch operating piston member is radially deformed caused by the repeated contact to a stopper member. SOLUTION: An annular release groove 19 for avoiding the contact of the outer periphery of the outer end surface of a clutch release piston member 12 and a contact surface 17a of a stopper member 17 is formed on the clutch release piston member 12. Therefore, even if the outer end of the clutch release piston 12 is radially deformed caused by the repeated contact of the outer end surface of the clutch release piston member 12 with the contact surface of the stopper member 17, interference is not generated between the outer end of the clutch release piston member 12 and a cylinder member 11 as long as the radial outward deformation amount does not exceed the radial dimension of the release groove 19, and the clutch release piston member 12 is reliably restored.

Title: Amorphous solar cell
Inventor: ITOZAKI HIDEO
IPC: H01L31/04
Filed: 1987-03-13
Abstract: PURPOSE:To improve the sensitivity of an amorphous solar cell for a long wavelength light by adding P-type and N-type doping materials to an I-type layer of a PIN solar cell formed of amorphous SiGe. CONSTITUTION:An N-type additive and a P-type additive are simultaneously added to an amorphous SiGe:H film for forming an I-type layer in an amorphous solar cell of PIN structure. If an excessive amount is added, a new defect is generated contrarily by the excessive additive. Accordingly, the defect in the l-type layer formed at the time of forming an s-SiGe can be set in an inactive state in which it does not operate as a function of trap or recombination center. Thus, the amorphous solar cell having excellent long-wavelength sensitivity is obtained.

Title: Control device for automatic transmission
Inventor: WATABE SHINJI
IPC: F16H59/38
Filed: 1990-03-08
Abstract: PURPOSE:To shorten the invalid stroke time of piston and stabilize the changeover timing of a hydraulic friction element by setting the discharge amount of an electric/hydraulic converting valve to the max. value during the period since a shift command is given until the friction element attains the coupling start point. CONSTITUTION:In No.1 gear position a rear clutch C2 is coupled with a low reverse brake B1. In shifting from No.1 to No.2 position for ex. in case the engine is on the driving side, changing-over of a friction element is made smoothly by performing coupling of a second brake B2 while the low reverse brake B1 is disengaged from No.1 position, and the braking pressure is controlled so as to attain the second position while torque variation on the output shaft is suppressed. Because the piston cylinder of the second brake B2 is filled with oil while the discharge amount of valve is set to the maximum, the duty ratio of duty solenoid valve 44 is made 100% for placing the output.

When time T+t1-t2 (T is the expected time at which the flow rate of return effluent water varies) elapses, correction of injection of chlorine into return effluent water is renewed. The rate of injection of chlorine is calculated, this signal is transmitted to a subordinate controller 15 through a date transmitting device 18 and the chlorine injector 3 is controlled.

Title: Tape tension controller
Inventor: OOHIRA SATORU
IPC: B65H59/38
Filed: 1979-05-14
Abstract: PURPOSE: To make it possible to hold tape tension constant at any time by changing the torque of a take-up side motor corresponding to a tape speed and the turning speed of the take-up side motor.  
     CONSTITUTION: When tape 9 is driven at a certain speed, a signal appears at turning detector 4 and triggers monostable multivibrator 11 via amplifier 10 to generate a pulse. This pulse is differentiated 12 and applied to constant-current circuit 13. As a result, capacitor 20 of saw-tooth wave generating circuit 19 is charged by the output of circuit 13. On the other hand, the rotataional frequency of motor 7 varies with the wind diameter of tape 9, and consequently turning detector 8 generates a signal. This signal is differentiated by differentiating circuit 18 and its positive differential pulse discharges capacitor 20. The saw-tooth wave output of circuit 19 is peak-held by peak holding circuit 22 to obtain a DC voltage, which is applied to motor driving circuit 25 to drive motor 7. At this time, the torque of motor 7 is varied according to a change in the intervals of pulses output from circuit 18.

Abstract: PURPOSE:To prevent the occurrence of a warp in a positive electrode and improve the performance of a battery, by annealing a metallic net member prior to pressure- molding said member with a positive electrode mixture into an integral assembly. CONSTITUTION:A metallic net member 2, which has previously been subjected to an annealing treatment, and a positive electrode mixture 3 are integrally pressure- molded into a positive electrode 1, which is then assembled in a battery. Since this construction can prevent the occurrence of a warp in the positive electrode 1, a battery of a good performance is obtained. The annealing treatment of said metallic net member 2 is carred out by first red-heating a metallic net, for example, to a temperature of 700-1,000 deg.C and for about 1-20 minutes and then slowly cooling it down. From the thus-annealed metallic net member, any electrically poor conductive substances such as metal oxides, metal carbides and the like occurred on the surface of the member are preferably removed and then it is pressure-molded with said positive electrode mixture.
