Title: Power supply
Inventor: OKAMURA MICHIO
IPC: H01G11/10
Filed: 1993-08-31
Abstract: PURPOSE:To prevent a consumptive loss caused by an overload on the battery side, by using electrical double layered capacitors with smaller internal resistance and larger electrostatic capacity than those of a secondary battery, and connecting the double-layered capacitors in parallel through a variable impedance element. CONSTITUTION:When an electrical double capacitor (C1) is completely discharged to zero volt and connected to a battery (VB), the whole voltage of the battery (VB) is applied to an incandescent lamp (a variable impedance element) (RV) and the incandescent lamp is lit, and thereby a current is carried. Then, the capacitor (C1) is charged gradually up to a voltage equal to that of the battery (VB). At this state, the current carried at the incandescent lamp (RV) is lowered up to zero and the resistance is minimized. When a load (IL) is a motor, for example, with large electromotive power, most of the energy is supplied from the capacitor (C1). After a working current returns to a normal state, the working current is supplied in a balance between the remaining capacity of the battery (VB) and the resistance of the incandescent lamp (RV), while the capacitor (C1) is charged.

Abstract: PURPOSE:To prevent the temperature rise of inductive load, and to reduce power consumption by applying first voltage when the inductive load is driven and second voltage lower than first voltage to the inductive load after a fixed time passes after drive. CONSTITUTION:When a power switch 2 is turned ON, the base currents of a transistor 7 fluctuate as shown in the graph, and the transistor 7 is brought to a conductive state. Voltage (first voltage) of VCC-VCE is applied to a solenoid 1 at that time, and the solenoid 1 conducts attraction operation. When both-end voltage of a resistor 6 drops with the rise of capacitor voltage and the time t1-t0 determined by a capacitor 5, resistors 6, 7 and a transistor hPE passes, the transistor 7 is turned OFF, and voltage (second voltage) decided by RL and R3 is applied to the solenoid 1 at that time. The second voltage is lower than an initial value VCC-VCE, and the solenoid 1 is left as it is attracted.

Filed: 1987-09-22
Abstract: PURPOSE:To measure the contacting force of a contact point indirectly without disassembling an electromagnetic relay by finding an armature following time from a vibration signal generated in the contact switching operation of the electromagnetic relay. CONSTITUTION:When a driving signal DRV is supplied to the base of a transistor (TR) Q1 for driving a relay coil R1 connected in series with a driving power source P1, the contact point (r) of the electromagnetic relay 10 is switched from a break contact point B to a make contact point M. At this time, the vibration signal S collected by a vibration sensor 30 is inputted to a time measuring circuit 50 through an amplifying circuit 40. Then the output of an oscillation circuit OSC is counted by a counter CNT 2 only while the output of an AND circuit AND 2 goes high to obtain the armature operation following time. This armature operation following time is multiplied by a constant coefficient which is found previously experimentally to find the contact contacting force in the operation.

Abstract: PURPOSE: To solve the overshooting unevenness in the corner part of a panel surface and form a glare shielding film uniform over the whole area of the panel surface by mounting a cover body on the panel part of a picture tube through a panel installing hole, and mounting an overshooting unevenness preventing fairing plate on the cover body. CONSTITUTION: A picture tube 1 is inputted to a rotating head part by a carrying device. A cover body 2 is fitted to the panel part of the picture tube 1 through a panel installing hole 2a. A liquefied glare shielding material is applied to a panel surface 1a through an application nozzle arranged above the picture tube 1. Thereafter, the picture tube 1 is rotated at high speed together with the cover body 2 by a rotation driving source to form a glare shielding film on the panel surface 1a of the picture tube 1. The flow of air on the panel surface 1a is controlled by fairing plates 3a, 3b mounted on the cover body 2, and the flow of air is properly suppressed by the rectifying plates 3a, 3b particularly to the corner part of the surface 1a.  Thus, the glare shielding material applied onto the surface 1a is uniformly stretched onto the peripheral side of the cover body 2 by the centrifugal force accompanying the rotation of the picture tube 1, so that the glare shielding material can be sufficiently delivered to the corner part of the surface 1a.
