Title: Semiconductor laser
Inventor: MUKAI SEIJI
IPC: H01S5/00
Filed: 1985-04-12
Abstract: PURPOSE:To make the two-dimensional switching of the radiated beam possible in the direction of scanning or diflection, by providing a electron density distribution in an active layer controlled by the electrode with the gradient not only in the direction of the plane parallel to the element substrate but also in the other directions. CONSTITUTION:On the P-type semiconductor substrate 101, the N-type semiconductor 102 is grown, on which the groove 102a for current injection is formed. The P-type semiconductor 103, the N-type semiconductors 104, 105 and 106, and the P-type semiconductors 107 and 108 are grown. After the insulation film 109 is formed, the grooves 109a for current injection is installed thereon, and the electrodes 101, 111 and 112 for current injection are formed. When the voltage is impressed between the electrodes 112 and 111, the current is injected from the groove 109a and the active region 113b emits light. On the other hand, when the voltage is impressed between the electrodes 110 and 111, the current is injected from the groove 109b, and the lower active region 113a emits light. As the injection currents into the active regions 113a and 113b can be independently controlled, the gradient of the injection current density between the active layers can be controlled. Thus, the deflection of beam occurs in the upper and lower directions in the semiconductor layers.

Title: Cooling system for electric vehicle
Inventor: SEKINO HIROICHI
IPC: B60H1/32
Filed: 1993-04-05
Abstract: PURPOSE:To carry out harmless and efficient cooling by leading a hot temperature and high pressure compressed refrigerant gas into an accumulator located at the low pressure side in a refrigerating cycle. CONSTITUTION:A low temperature, low pressure refrigerant which is reduced in pressure in an expansion valve 7b is fed to an accumulator 10 through a solenoid valve 9a after cooling an electric motor 6. However, when a pressure detected by a pressure sensor 12 is lower than a suction pressure of a compressor 1, it cannot be adjusted stably by a suction pressure regulating valve 11 only. Therefore, when a pressure valve is lowered than the suction pressure, a solenoid valve 9b on a bypass line 14 is opened to lead a part of high temperature, high pressure refrigerant gas into the accumulator 10. Thus the stable operation of refrigerating cycle under a specified pressure condition can be maintained, and also its equipment constitution can be facilitated.

Title: Method of exposing electron beam
Inventor: GOTOU HIDEKAZU
IPC: H01L21/027
Filed: 1979-06-22
Abstract: PURPOSE:To eliminate the affection of both linearities of a large section deflecting systen precise D/A converter and a small section deflecting system high speed D/A converter in a method of exposing an electron beam and accurately draw an infinitesimal figure bridged over reference regions by aligning the high speed D/A converter with the precise D/A converter. CONSTITUTION:Marks m1-m3 are attached to the vicinity of the reference sections A1, T1 and A20 on a specimen 5. When specifying the position of the mark m1, a computer 10 deflects the large sections by a deflector 7 through an information transmission mechanism HSC8 and a high accuracy D/A converter 14 until detecting it by a detector 23. When specifying then the mark m2, the first , third and fifth bits of the most significant bit of the D/A converter 14 are turned on and horizontally deflected to transmit signals through the D/A converter 27 from the mechanism HSC8 until detecting the mark m2 so as to control the amplification gain 15. Subsequently, only the fifth bit of the D/A converter 14 is turned off, and the electron beam is returned to the position P0. Then, the D/A converter 14 is turned on at the first bit of the converter in the present state to control the amplification gain 13 by the controller 26 until detecting the mark m2 and to deflect the small section by the deflector 6. When the linearities of the large and small sections are aligned in the deflecting systems 6 and 7 at the maximum point P0 of the deflecting width, it can be similarly operated in a direction Y also with the marks m1 and m2. As a result, the infinitesimal figure is not deformed over the two reference regions.

Title: Clock generator of memory with redundancy bit
Inventor: MUROTANI KITOKU
IPC: G11C29/00
Filed: 1983-05-06
Abstract: PURPOSE:To prevent malfunction by changing the propagation path of a clock signal depending on the presence of selective use of a redundancy bit so as to give a delay to the clock at the use of redundancy bit even if a memory is provided with the redundancy bit. CONSTITUTION:When it is not necessary to use a redundancy bit and a fuse 40 is not blown, the 4th stage clock generator 4 generates a clock with less delay same as the 2nd stage clock generator in response to an output of the 1st stage clock generator 1, a normal decoder 11 is controlled and a normal memory array 20 is accessed by being delayed for the normal speed. On the other hand, if the fuse 40 is blown to a defective bit, a redundancy memory 21 is accessed by the clock of the generator 2 via a spare decoder 30, the decoder 11 is controlled by the clock delayed by two stages outputted from the generator 4 via the clock generator 3 so as to prevent malfunction such as multi-selection of the decoders 30, 11. Thus, even if the redundancy bit memory is provided, the normal operation is attained normally without delay.

Filed: 1981-05-23
Abstract: PURPOSE:To permit a sense gear and a cam to rotate at angles of deviation smoothly and securely, by coupling a pulley cam with the sense gear while disengaging a drive gear from the pulley cam on the stop of rotation. CONSTITUTION:When a drive gear 9 stops, a pulley cam 14 is pressed down as shown by an arrow H by the mutual relating function among recessed parts 40- 42, engaging projections 44-46, and a coil 49, so that a hook pawl 51 meshes with the non-return tooth part 58 of a sense gear 53. Therefore, the sense gear 53 rotates together with the pulley cam 14 in the same direction, namely, as shown by an arrowI. The rotation of this sense gear 53 allows a lock lever 61 to rotate around a supporting shaft 62, as shown by an arrow G, at an angle of deviation through tooth parts 59 and 65, and consequently an operation-key lock plate 68 is moved as shown by an arrow J through a lock part 67 to unlock operation keys, thus automatically stopping the cassette tape recorder.

Title: Direction change-over valve
Inventor: UENO KATSUMI
IPC: F15B11/16
Filed: 1982-05-11
Abstract: PURPOSE:To enable respective actuators at the upstream and downstream sides to set to the desired speed balance in composite operation by flowing to an outflow port only pressurized oil having flow from a pump port limitted when pressurized oil in the upstream side neutral port is shut off. CONSTITUTION:When a controlling valve (not shown) at the upstream side is operated while a direction change-over valve 1 is operated, pressurized oil from an oil path 32 to an upstream side neutral port N1 is shut off so that the pressurized oil is not flowed from the neutral port N1 to the outflow port A, but only pressurized oil from a pump port P is flowed. However, the pressurized oil flow flowed from the pump port P to the port A is limitted by a throttle portion 4 to be reduced. Thus, the pressurized oil flow supplied to an actuator is reduced to decrease the speed of the actuator.
