Title: Gearshifting controller for automatic transmission
Inventor: KOSHIZAWA TOSHIBUMI
IPC: B60W10/11
Filed: 1986-06-26
Abstract: PURPOSE:To make safety running attainable without overrunning an engine, by controlling it so as to prohibit the gearshifting within the set time at a time when a decrement rate of car speed is larger than the specified value. CONSTITUTION:An electronic controller 9 connects its output port 9c to a clutch actuator 3, a hydraulic mechanism 4 and a transmission actuator 5. And the input port 9d is connected to a clutch actuator 3, various sensors 6c, 7a, 8a, 8b and 10, and an accelerator pedal 11 as well as a brake pedal 12. In this case, when a decrement rate of the car speed detected by the sensor 8b is larger than the specified value, it is controlled so as to prohibit a speed change within the set time. That is to say, when it is judged to be a wheel lock state from the decrement rate of the car speed, it is controlled so as not to change a gear shifting lever unless the specified time elapses even after a brake is deenergized.

Title: Sensitivity confirming specimen gas of contact combustion type infalmmable gas density detector
Inventor: TODOROKI SATOSHI
IPC: G01N1/22
Filed: 1979-11-22
Abstract: PURPOSE: To obtain the specimen gas which is stable extending over a long period of time, by reducing the oxygen concn. in the specimen gas to the extent of the limit amount required for the combustion exothermic action.  
     CONSTITUTION: Gas which does not contain oxygen is made a base, and oxygen whose amount is limited to that which is required for the combustion exothermic action, and component gas of the amount required are mixed into said gas. For instance, nitrogen is used as the base gas which does not contain oxygen, a gas  cylinder is filled by pressure with the specimen gas which has mixed 500ppm oxygen and 120ppm ethanol, and when it is preserved for a long period of time, ethanol is scarcely reduced, and its high stability can be obtained. According to this constitution, when the concn. of oxygen is 500ppm, the detecting sensitivity is lowered by 5%, and the sensitivity of the detector can be confirmed enough by correcting the result of measurement. In this regard, in case when the concn. of oxygen is 2,000ppm, deterioration of the detecting sensitivity is nearly negligible, and correction is not required.

Title: Safety control unit for speed-sensitive type power steering device
Inventor: TAKAOKA SHUJI
IPC: B62D6/02
Filed: 1987-06-17
Abstract: PURPOSE:To eliminate factors causing the unstable steering feeling at the high- speed travel by cutting off the electric power feed to a step motor driving a variable throttle valve provided on a pressure fluid pipeline when the abnormality of a vehicle speed sensor is detected. CONSTITUTION:The abnormality of a vehicle speed sensor 1 is detected when a micro-computer 14 detects that the vehicle speed signal has a change higher than a preset value. At the abnormality detection, all transistors in a driver circuit 15 or a switching circuit 17 are turned off to cut off the electric power feed to a step motor 6 driving a variable throttle valve provided on a pressure fluid pipeline. Thereby, the step motor 6 is stopped at a rotating position where the variable throttle valve is squeezed to the maximum by a return spring fitted to a rotor shaft, and the steering reaction force is prevented to become too light. Accordingly, the safety and stability at the abnormality occurrence particularly during the high-speed travel can be improved.

Filed: 1989-06-14
Abstract: PURPOSE:To improve photoresponse speed by specifying the atmosphere in case of heat-treating CdS, CdSe, or CdS/CdSe thin film in the atmosphere which contains CdCl2. CONSTITUTION:A film, which is mainly composed of CdS, CdSe, or CdS/CdSe containing a very small amount of Cu, is heat-treated in the atmosphere which contains CdCl2. The concentration of O2 in the atmosphere at this heat treatment is set to 20-60% (for the rest, N2). With the increase of O2 concentration, photocurrents Jp decrease, and according to that gamma4 decrease, but gammar does not increase and becomes almost fixed. Moreover, the rise time till Jp reaching 50% from O is defined as gammar, and the time till its decreasing to 50% from a saturated value is defined as gammad. What is more, if O3 concentration is 60% or more, Jp becomes too small, and circuit cost becomes high. Hereby, photoresponse speed can be improved.

Title: Distributed feedback semiconductor laser element
Inventor: MUKOHARA KAZUMASA
IPC: H01S5/12
Filed: 1995-06-19
Abstract: PURPOSE: To increase the fabrication yield by employing a multilayer structure of at least two kinds of semiconductor material having different refractive indexes in the diffraction grating thereby lowering the effective refractive index and fabricating the diffraction grating at high accuracy. CONSTITUTION: A diffraction grating 2 has multilayer structure, e.g. three-layer structure, where n-InGaAsP 11 and n-InP 10 are laminated alternately. The diffraction grating 2 has an effective refractive index equal to the average of the refractive index of n-InGaAsP 11 and n-InP 10. Since the diffraction grating in the semiconductor laser element has properties similar to those of diffraction grating having low height, the effective height of diffraction grating can be lowered while reducing the error and the accuracy is enhanced substantially. This structure increases the probability of fabricating a DFB semiconductor laser element having good optical output characteristics and the DFB semiconductor laser element can be fabricated at high yield.
