Title: Pulse amplifier circuit
Inventor: YOSHIDA TADAO
IPC: H03K4/06
Filed: 1979-01-22
Abstract: PURPOSE:To improve switching efficiency while improving a power loss due to a relay current by connecting an inductance element to the base of a complementary transistor and then by interposing a diode between the input and output of this inductance element. CONSTITUTION:Even if a current based upon the charge of coil 17a constituting a low-pass filter would try to flow through transistor 9 or 15 right after pulse-width- modulated signal supplied to the connection point of emitters of transistors 15 and 16 changes from a negative voltage to a positive voltage or oppositely, it is cut off by diodes 21a and 21b and flows through diodes 19 and 20. In addition, the time when transistors 15 and 16 turn on is delayed by coils 22 and 24, but since diodes 21a and 21b are interposed, the time is not delayed and at the same time, the ON time can be eliminated.

Title: Heat treatment jig
Inventor: TATEFURU NOBORU
IPC: H01L21/22
Filed: 1981-01-21
Abstract: PURPOSE:To unify the effect of heat treatment of wafers by a method wherein a jig for heat treatment on which materials to be treated are to be put and to be inserted in a core tube is made to have structure of which heat capacity is made to increase in proportion to advance toward the inner part of the core tube. CONSTITUTION:Height of circular arc type protruding parts 9 on both the sides of the jig 7 for temperature compensation is made to become higher gradually in proportion to advance toward the inner part of the core tube 1. When the wafers 5 are to be inserted in the core tube 1, a mounting jig 8 on which the wafers 5 are put is put on the jig 7 for temperature compensation, and the jig 7 for temperature compensation is inserted in the core tube 1 in this condition to heat treat the wafers 5. Because heat capacity of the jig 7 for temperature compensation becomes larger in proportion to advance toward the inner part, temperature drop in the core tube 1 is large because of temperature rise thereof, and distribution of temperature in the core tube 1 is unified as a result.

Abstract: PURPOSE:To prevent unauthorized reutilizing by a general user by generating a start signal to start a timer unit and using an auxiliary unit for which the regeneration of the start signal is inhibited when the timer unit starts. CONSTITUTION:When power is supplied, a start data sending request instruction is outputted from a control part 8 of a timer module (TM) 2 to a control part 17 of an auxiliary unit 3, and a large scale integrated circuit 5 is made into a start data input waiting state. When the start data are inputted from a RAM 18 of the unit 3 to a RAM 13 of the TM 2, it is compared and decided whether set start data stored in a ROM 14 coincide with the input start data or not in a comparing part 15. When both the data coincide with each other, a coincidence signal is given to the control part 8, the work program of the circuit 5 is started, and an erasing instruction is outputted for the unit 3. In the unit 3, when the start data sending request instruction from the TM 2 is inputted, the start data previously stored in the RAM 18 are outputted to the TM 2. After that, the unit 3 is made into an erasing instruction from the TM 2 waiting state, and when the instruction is inputted, the start data stored in the RAM 18 are erased.

Title: Optical head
Inventor: YOSHIHARA KAZUHIRO
IPC: G11B7/135
Filed: 1987-01-16
Abstract: PURPOSE:To ensure the stabilized recording and reproducing actions with an optical head by setting the light emitting points of the semiconductor lasers excluding the one set on the optical axis of a collimator lens with prescribed level differences secured in the direction of the optical axis of the collimator lens against the light emitting point of the semiconductor laser set on the optical axis of the collimator lens. CONSTITUTION:The light emitting points 33a and 33c of laser diodes LD3a and 3c are set with level differences secured in the direction of an optical axis against the light emitting point 33b of an LD3b so that the bend of an image surface due to a focusing optical system is corrected. Both points 33a and 33c are not set on the optical axis of a collimator lens 4 and therefore the light beams emitted from the points 33a and 33c and transmitted through the lens 4 and a focusing lens 8 are made incident obliquely on the lenses to cause the bends of the image surfaces. These image surfaces, however, are connected to each other on the same plane of an optical disk 9 owing to a level difference (d). As a result, three beam spots sent from the points 33a-33c on the disk 9 are even to secure the stable recording and reproducing actions.
