Abstract: PURPOSE:To eliminate noise due to a parasitic capacitance by connecting a back gate terminal of an analog switch consisting of MOSFETs to a constant voltage source and using a positive/negative stable voltage as a control signal applied to the gate terminal. CONSTITUTION:An output of a signal processing circuit AC having a stable constant voltage source is given to the back gate of P channel PS1 and PS2 of the MOSFETs constituting the analog switch. Further, the circuit AC is connected also to one end of resistors R1, R2 increasing the gate voltage of the FETs PS1, PS2, NS1 and NS2 to a constant voltage Vc. The other end of the resistors R1, R2 is connected to a drain of the FETs NB1, NB2. The gate of the FETs NB1 and NB2 is controlled by a logic circuit CLC controlling the sequence of operation of a range finder, its drain voltage becomes a line GND potential when the FETs NB1, NB2 are turned on and reaches a potential of a line LVc when they are turned off.

Title: Recording component
Inventor: KATOU KEIZOU
IPC: G11B7/241
Filed: 1978-07-14
Abstract: PURPOSE: To avoid the surface coarseness of the plastic base from being affected to  the S/N of signal, by providing the macromolecular substance using non-photo- sensitive polymer between the recording thin film emitted with the machining  beam and the plastic base.  
     CONSTITUTION: On the plastic base 1 such as polyvinylchloride resin having preferrably 40°C or more softening point, the non-photo-sensitive polymer solution such as rubber system polymer is coated and dried with spin coating or the like to form the macromolecular layer 2, 0.2 to 1μm thick preferrably.

Title: Controller for continuously variable transmission
Inventor: HISAMURA HARUYOSHI
IPC: B60W10/10
Filed: 1986-04-16
Abstract: PURPOSE:To make stable operation continuable even in case of a sensor being out of order and so on, by stopping feedback control when a device detecting an actual input rotational speed gets out of order, and making a controller so as to do feedforward control instead. CONSTITUTION:When something trouble in a device detecting an input rotation speed is detected by a trouble detecting device, a gear shifting command device outputs a gear shifting command signal to a gear shifting actuator on the basis of only a signal out of a feedforward controlling device. Therefore, a transmission gear ratio is controlled so as to become the preset desired transmission gear ratio on the basis of, for example, car speed and engine load. With this constitution, even if an apparent deviation between the actual input rotational speed and the desired one grows large, an improper transmission gear ratio is in no case commanded, so that such a state as being almost the same state as the transmission gear ratio up to just before the trouble occurs is maintained, thus a variation in a sudden operating state will not happen there.

Title: Power supply protection circuit for radio communication equipment
Inventor: ONO KUNIHARU
IPC: H04B1/40
Filed: 1985-04-22
Abstract: PURPOSE:To eliminate the need for a protection relay by utilizing the wired- logic between the 1st transistor (TR) for power supply used for a constant voltage circuit and the 2nd TR controlling the 1st TR. CONSTITUTION:In throwing a power switch 2 provided to a power supply circuit 1, an unregulated DC is fed to the base of a TR Q3 via a terminal 1a, the terminal 7b of a start circuit 7 and a resistor R5, the TR Q3 is turned on to switch the level of a terminal 7c to a reference potential. In confirming a load voltage comprising a resistor R6 and a TR Q4, a load voltage confirming circuit 8 connects the terminal 7a of the start circuit 7 to the reference potential point. Thus, the start circuit 7 is restored. When a PTT button 9 is depressed before the application of power supply and the transmission state is attained, since the terminal 7a is connected to the reference potential point even when the power switch 2 is turned on, the TR Q3 is not operated. Thus, when the load is in the sending state requiring a large power consumption, even when the power is applied, no power is supplied to a load.

IPC: G01N15/14
Filed: 1984-05-01
Abstract: PURPOSE:To enable the three-dimensional counting of floated particles without contact with a medium in which said particles are present, by irradiating floated particles with luminous flux from a slit-lamp and two-dimensionally observing the same from the direction almost vertical to the irradiation direction while calculating a volume from an observation range and the width of luminous flux. CONSTITUTION:Slit luminous flux 11 converged to a medium, in which floated particles are present, is irradiated. Because the luminous flux 11 is converged to a max. degree at a surface 12, it is observed in a length of 1mm. before and behind said surface 12 from the direction almost vertical to the almost central surface of the width of the luminous flux 11 by a slit-lamp microscope 2. An image is formed on the image pick-up surface of a TV camera 4 on trial through an image intensifier 3 and the counting of floated particles is performed by an image processing apparatus 6. The volume of a measuring part is determined by the area of a cursor (a square having a side length of 2mm.) and the width of luminous flux 11 and floated particles can be counted three-dimensionally.
