Title: Dc motor control circuit
Inventor: ABE KIYOMI
IPC: H02P1/22
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of control circuit while facilitating the setting of ON/OFF speed and to reduce current consumption at the time of stand-by by switching the voltage or current being fed to a DC motor using a semiconductor device. SOLUTION: When a power supply terminal 11 is applied with a voltage or current of + level and a power supply terminal 12 is applied with a voltage or current of - level or GND level with respect to the power supply terminal 11, a differentiated waveform determined by a capacitor Cd and a resistor (R2) appears at point A and inputted to the gate of a second FET Q4. The second FET Q4 is turned on to start rotation of a DC motor 'M'. When the DC motor 'M' is stopped forcibly upon elapse of a predetermined time, an overcurrent flows through the DC motor 'M' and the voltage across a resistor R4 increases. The resistor R4 turns a second transistor Q2 off for the voltage generated by the steady current of DC motor 'M' and turns the second transistor Q2 on for the voltage generated by the overcurrent.

Title: Semiconductor device
Inventor: HAYAMA MASAHIDE
IPC: H01L29/06
Filed: 1990-08-17
Abstract: PURPOSE:To restrain a leakage current by a radiation between faced diffusion layers of an opposite conductivity type and to enhance a radiation-resistant property by providing a diffusion layer, of one conductivity type formed on the surface of a semiconductor layer on the rear surface of a thin insulating film formed directly under or close to a region sandwiched between the diffusion layers. CONSTITUTION:This semiconductor device is constituted of the following: a P-well 2 formed on a silicon substrate 1; a thick SiO2 film 3 formed selectively on the surface of the P-well 2 and which partitions an interconnection formation region sandwiched between a diffusion-layer formation region and a diffusion-layer formation region; N<+> type diffusion layers 4 formed in the P-well 2 in the diffusion-layer formation regions; a P<+> type diffusion layer 5 formed in the P-well 2 in the inter-connection formation region sandwiched between the adjacent N<+> type diffusion layers 4; and an interconnection 6 by an Al layer or a polycrystalline silicon layer formed on a thin SiO2 film whose thickness is nearly the same as that of a gate oxide film formed on the P<+> type diffusion layer 5. When the thin oxide film is used in this manner, an electric charge generated per unit volume is reduced. When the P<+> type diffusion layer is formed, it is restrained that a channel is formed under the thick oxide film, and a resistant property is enhanced.

Title: Semiconductor laser protective circuit
Inventor: SANADA TAKESHI
IPC: G11B7/125
Filed: 1987-08-31
Abstract: PURPOSE:To prevent excessive voltage being applied to a semiconductor laser by controlling and monitoring a semiconductor laser based on a feedback amount of a photodiode and by stopping current supply to the semiconductor laser when the feedback amount is less than a standard value. CONSTITUTION:Should a circuit and LD1 are disconnected, the output current of PD2 stops and the output voltage of an amplifier 3 lowers. If a comparator 7 detects the above condition, the output of a flip-flop 8 changes from High level to Low level, a gate circuit 9 closes, a transistor 5 turns ON through a buffer gate 4, and a transistor 6 turns OFF thereby. Thus the current supply to LD1 can be stopped. Moreover, a switch 18 turns ON by the output of the gate circuit 9 thus grounding a collector of the transistor 6 and preventing excessive voltage over the rating from being applied to LD1.

IPC: B23Q16/10
Filed: 1986-09-16
Abstract: PURPOSE:To simplify a functional mechanism while to improve an indexing speed of a tool rest, by forming a device into construction such that a turning shaft is turned indexing the tool rest while controlling its positioning. CONSTITUTION:If a driving motor 11 is normally rotated, a turning shaft 3 is turned advancing a nut 5 in the axial direction and floating a tool rest 2 from a tool feeding bed 1, and a coupling 6a is detached from a fixed coupling 6b. And the tool rest 2, which is turned to be indexed by a rotary feed motion of the nut 5, is stopped if a dog on a sequencer 13 is detected by a sensor in the next division angular position. Next the driving motor 11, if it is reversed, turns only the turning shaft 3, and the tool rest, in which the movable coupling 6a meshes with the fixed coupling 6b by retracting the nut 5, performs the positioning of a predetermined indexing angle. In this way, since the turning shaft 3 is turned indexing the tool rest 2 and performing the positioning, constitution is compact being simplified, while an indexing speed can be increased faster because of mechanical sequence action.

Title: Radiation measuring apparatus
Inventor: UYAMA KIICHIRO
IPC: G01T1/17
Filed: 1985-09-30
Abstract: PURPOSE:To measure radiation quantity over a wide range, by selecting an analog-converted signal of an output of a radiation detector and an integration signal thereof. CONSTITUTION:A radiation detector is made up of a scintillator 1 for discharging a photon in response to a radiation and a photomultiplier tube 3 for multiplying the photon and an output signal thereof is supplied to a F/V converter 7 and an integrator 9 through an amplifier 5. An output signal of the integrator 9 is fed to a switching unit 15 which opens a switch 11a and closes a switch 11b as the voltage thereof exceeds a reference voltage. When it is under the reference voltage, conversely, the switching unit closes the switch 11a and opens the switch 11b. Therefore, based on the reference voltage, output signals S7 and S9 of the converter 7 and the integrator 9 are selected and the output signal S7 of the converter 7 is used when radiation is small while the output signal S9 of the integrator 9 when radiation is large. This enables accurate measurement of radiation over a wide range.
