Title: Residual capacity display circuit of battery
Inventor: ISAKA ATSUSHI
IPC: H02J7/00
Filed: 1985-03-14
Abstract: PURPOSE:To perform the display of the residual capacity of a battery with good accuracy, by resetting the integration quantity of an integrator circuit for integrating the charge quantity to a battery when the voltage of the battery falles below set voltage. CONSTITUTION:When the voltage of a battery B falls below set voltage, it is necessary to charge the battery B. Because switches SW1-SW3 are respectively closed to the side of a C-terminal at the time of charging, the battery B is charged and a current is flowed to a potential memory element M through a resistor R1 to raise potential. With the rising of this potential, LED1-LED5 are successively lighted by the outputs from comparators CP1-CP5. Subsequently, when the switches SW1-SW3 are closed to the side of a D-terminal and load L is driven by the battery B, a part of the discharge current from the battery B flows to the element M which is, in turn, discharged to lower potential. LED1-LED5 are also turned OFF and the element M is shortcircuited to reset an integration amount. Because the element M performs integration from the beginning at the charging time of the battery B even if the charging and discharging of the battery B is repeatedly performed, the residual capacity of the battery can be displayed with good accuracy.

Title: Surface inspecting device
Inventor: NAKAI NORIHIRO
IPC: G01N21/892
Filed: 1988-03-04
Abstract: PURPOSE:To improve the inspection accuracy by setting the cementing surfaces between convex lenses constituting a condenser lens array in parallel to the optical path of the ordinary light at a scanning position. CONSTITUTION:A scanner 9 projects a light beam 10 at a specific angle of scanning to form scanning track 21 on the surface of a body 11 to be inspected at right angles to a scanning center line 20. The lens array 13 for convergence consists of six spot lenses 13a, 13b... consisting of convex lenses, and the adja cent lenses 13a, 13b... are cemented mutually on cementing surfaces 18a, 18b..., which slant to the center line 20. Consequently, when the ordinary light 12a is incident nearby the cementing surface 18a and distributed by the cementing surface 18a, light 12m entering the lens 13a is refracted to the optical-axis side of the lens 13a and light 12n entering the lens 13b is refracted to the optical-axis side of the lens 13b. Then the cementing surface 18a slants not to enter the optical paths of the light beams 12m and 12n, which are therefore incident on the cementing surface 18a, so that no artificial defect signal is generated.

Filed: 1985-03-13
Abstract: PURPOSE:To attain two-way communication without using a transformer by providing a diode bridge and an LPF to a remote controller side receiving a DC power from a cable and connecting a transceiver between them. CONSTITUTION:Power is applied to a power supply 1B of plural remote controllers RCTY from a DC power supply 1A of a main controller MCTX and two-way communication for a control signal is attained by superimposing an AC signal (f) on the control signal through the cable E. In this case, the MCTX side is provided with an inductance L1 blocking the signal (f) from the output of the power supply 1A and the transceiver 2A is connected between the cables E via a capacitor C1. At the RCTY side, a DC power is applied to the device 1B via a full wave rectifier diode bridge DB and an LPFL2 and the transceiver 2B is connected between the DB and the L2 via a capacitor C2. Since a DC current flows always to the DB, the operating point of the diodes is biased, the nonlinearity is neglected, the loss of the signal (f) is less and the cables are made nonpolar.

Filed: 1991-03-15
Abstract: PURPOSE:To prevent thermal distortion of material to be treated due to a roll by adjusting the packing ratio of a heat resistant granular body packed in a void part around a refrigerant pipe of a roll axial center part. CONSTITUTION:A refrigerant pipe 2 is placed in a roll axial center part and a void part 6 is placed around the refrigerant pipe the void part is packed with a heat resistant granular body 9 as a heat transfer medium.
