Title: Electronically controlled automatic speed changer
Inventor: SEO NOBUHIDE
IPC: F16H61/04
Filed: 1983-01-27
Abstract: PURPOSE:To relieve shock likely to arise at the time of shift to No.1 speed position by providing separately No.2 shift-down speed change line, for the purpose of judging the speed change into No.1 speed, for a memory speed-change line, which is to judge the shift-down by reference to the number of revolution signal and load signal. CONSTITUTION:Signals from an engine load sensor 207 and a sensor 209 to sense the number of revolutions of the output shaft of a torque converter are fed in an electronic control circuit 200, and if a shift-down is judged by reference to the speed-change line entered previously in an RAM202 a shift-Down signal is emitted to control an electromagnetic means for a fluid operated actuator, and thus automatic shift-down is conducted. As said two speed-change lines are provided: No.1 shift-down speed change line to shift into any other position than No.1 speed and No.2 shift-down speed change line to shift into No.1 position, which is situated on the low turbine rotation side of torque converter being lower than the above. Accordingly shocks likely to arise at the time of shifting- down to No.1 speed position can be relieved.

Abstract: PROBLEM TO BE SOLVED: To create a high-performance semiconductor laser having a non-(100) plane MQW active layer on a (100) plane substrate, by forming the active layer on the non-(100) plane of the sidewall of a step formed by an anisotropic etching. SOLUTION: On a semi-insulation Fe-doped InP substrate 6, an undoped InGaAsP etching stop layer and an n-type InP clad layer 2 are grown in succession. Forming an SiO2 film in the corresponding portion to the clad layer 2 of a semiconductor laser, it is formed in the form of a step by an etching process. Subsequently, by a crystal growing process, an InGaAsP-MQW active layer 3 and a p-type InP layer 4 are grown in succession to bury them in the step. Thereafter, removing the SiO2 film, electrodes are formed on the n-type and p-type regions. The plane orientation of the side surface of the step can be controlled by the kind and concentration ratio of an etchant. The current constriction of the element is made possible by controlling the width of the active layer 3 by an etching or proton-implantation performed from the surface of the semiconductor laser element.

Filed: 1984-01-24
Abstract: PURPOSE:To effectively perform the backwashing of a particle bed without imparting an obstruction to dust collecting function and to improve the stability of a processing system, by providing a purified gas reflux means for using gas purified by the particle bed in backwashing the particle bed. CONSTITUTION:A reflux conduit 11 is connected between the lower part of a backwashing air chamber 10 and a part of a purified gas exhaust conduit 8 and a part of the purified gas of the exhaust conduit 8 is sent to the backwashing air chamber 10 under pressure through the reflux conduit 11 by operating the recirculation fan 12 interposed to the reflux conduit 11. As a result, because the purified gas of a purified gas chamber 7 is sent to the particles of the particle bed 6 after dust collection under pressure to backwash said particle bed 6, the amount of exhaust gas is not increased. Further, because the amounts of introduced dust-containing gas and the exhausted purified gas at the times of backwashing and non-backwashing become always constant, movement characteristics of the preceding and succeeding processes can be made stable.

Abstract: PURPOSE:To make it possible to supply hot water or cold water extremely in a short time by heat exchanging liquefied refrigerant with gasified refrigerant perfectly in an opposed current, installing a heated fluid penetration passage to a condenser, and a cooled fluid penetration passage to a vaporizer respectively, and making heated fluid refrigerant inside the vaporizer to flow counter. CONSTITUTION:A refrigerant liquefied gas heat exchanger 11 is installed in an attempt to heat exchange liquefied refrigerant from the outlet of a condenser 2 to an expansion valve 3 with gasified refrigerant from a vaporizer 4 to a compressor 1. The compressor 1, when driven, raises insulation compressed enthalpy i1' to i2'. Then, the refrigerant is heat exchanged with heated hot water in the next condenser 2, cooled under a constant pressure state, and turns into liquefied refrigerant. When further cooled, i3' under an excess cooling state is obtained. The route of heated hot water is formed based on an once through flow. Moreover, heat exchange is made with the refrigerant in a counter flow. Therefore, the refrigerant is cooled by fresh heated hot water constantly supplied, which equalizes the logarithmic mean temperature difference of the both with a lager value. Moreover, as for the outlet of a refrigerant condenser 2, excess cooling can be more effective by the heat exchange made by the heated hot water which flows in at an ambient temperature.

Abstract: PURPOSE:To prevent oil temperature from being increased by a back pressure valve by returning a hydraulic oil from a relief valve at its neutral position in a system in which a back pressure caused by a back pressure valve arranged in a feed-back passage is used as a pilot pressure in the solenoid direction switching valve. CONSTITUTION:Pilot pressure supplying circuits 48a and 49a are connected to an upstream side of the back pressure valve 50 arranged in a feed-back circuit 60 to be connected to the unloading circuit 18 and then the pilot pressure fluid to which a back pressure is applied is supplied. In the vent circuit 55 for the relief valve 54 arranged in the supplying circuit 15 is arranged a solenoid valve 56. When the direction changing-over valves 1a and 1b are at their neutral positions, the solenoid valve 56 keeps open the vent circuit 55, so that the relief valve 54 is also kept open and the pressure fluid is passed through the relief valve 54 and returned back to the tank T through the feed-back circuit 38. Thus, no back pressure is generated by the back pressure valve 50, so that it is possible to decrease an increased temperature of the pressure fluid.
