Title: Manufacture of electric double-layer capacitor
Inventor: TAKAGI KENJI
IPC: H01G11/54
Filed: 1988-04-28
Abstract: PURPOSE:To minimize an amount of split electrolyte when the electrolyte is injected into a case body and into a cap so that a polarizable electrode is impregnated with the electrolyte by establishing a negative pressure within the atmosphere for predetermined period of time, then restoring atmospheric pressure and repeating these procedures again. CONSTITUTION:A predetermined amount of electrolyte is injected into a case body 10 through a nozzle 18 and the case body 10 is set within a vacuum apparatus. The vacuum apparatus comprises a turn table 30 having a plurality of pits 31 arranged along the same circumference with a predetermined distance therebetween, and cup-like covers 32 provided for the respective pits 31 and movable vertically thereto. Each of the pits 31 communicate with a negative pressure source through a pipe 33. When the case body 10 containing the electrolyte is set in a pit 31, the cover 32 descends to close the pit hermetically while the negative pressure source is activated so that the pressure within the pit 31 is reduced for a predetermined period of time. Then, atmospheric pressure is restored in the pit and the procedures described above are repeated again. In this manner, an amount of the split electrolyte can be minimized.

Title: Dc current measuring apparatus
Inventor: NAKADA SHUHEI
IPC: G01R15/18
Filed: 1989-04-28
Abstract: PURPOSE:To miniaturize a high frequency power supply and to improve measuring sensitivity by monitoring the high frequency current flowing to the resistor connected to a condensor in series. CONSTITUTION:When a high frequency power supply A is operated in the vicinity of resonance frequency f0, even when the capacity of the power supply is small in this case, a large current can be let flow to a core 2. When the core 2 is saturated, the specific magnetic permeability of the core drops suddenly and, therefore, the inductance of the core 2 becomes almost zero. At this time, a pulse like large current further flows to a circuit. When a DC current of charged particles flows to the core 2 in an interlinkage manner in this state, a bias current flows to a coil 3. At this time, since the saturation time of the core 2 becomes slightly different, the generation time of the pulse-like large current also changes. When the shift of this time to a reference signal of frequency 2f0 is measured by a lock-in amplifier 6, the value of the current flowing to the core 2 in interlinkage manner can be measured.

Abstract: PURPOSE:To obtain large variation in amplitude even when a power source voltage is low by making an input voltage to an output voltage characteristic of a circuit consisting of two transistors steeper in a low band part of input voltage than in a high band part. CONSTITUTION:When an input voltage of an input terminal 10 is base voltage Vr1 or a transistor 15, both of TRs15, 16 cut off and correspond to a point (d). In the case where the input voltage of the terminal 10 is between base voltage Vr1 of TR15 and base voltage Vr2 of TR16, the state of conduction is caused, and the inclination K3 becomes K3=R14/R12 supposing that resistance of resistors 12, 14 is R12, R14 respectively. When the input voltage of the input termina1 10 is lower than the base voltage of TR16, i.e. in a range from point (e) to point (f), both TRs 15, 16 are in the state of conduction, and the inclination K4 is K4=R14(R12+R13)/(R12.R13) supposing that resistance of a resistor 13 is R13. When R12 is 5-9 times as high as R13, K3 can be set 6-10 times as much as K4.

Abstract: PURPOSE:To realize the miniaturization of a cassette tape recorder, by carrying out the position control of the head base for actions of cue and review by means of an action switching means including a brake releasing solenoid of the quick forward mode. CONSTITUTION:In the recording mode, a head base 2 is shifted against a spring 4 by the electric conduction to a head base solenoid 3. A brake plate 6 is pressed at the bent part of the base 2 and thus detached from a reel drive disk. In the FF and REW modes, a brake lever 9 is turned by the first solenoid to slide a working plate 11 against a working plate spring 12 and a brake spring 5. Thus a release arm 7 engaged with a slit 111 of the plate 11 via a coupling pin 17b is turned to press the plate 6. In the cure and review modes, the first solenoid works after a shift of the base 2 by the electric conduction of the solenoid 3. Thus the arm 7 turns to be positioned under a projected part 22 of the base 2. Then the base 2 is kept at the cure and review positions when the electric conduction is cut to the solenoid 3.
