Abstract:
The gas insulated switchgear includes a rotary shaft which penetrates a pressure vessel is connected with a moving parts which is housed in the pressure vessel by way of a lever, and is connected to the moving parts, and brackets which support the rotary shaft and are mounted on a mounting portion which is formed on the pressure vessel. The brackets are fixed to the mounting portion formed on the pressure vessel using a plurality of fixing bolts which are arranged in a spaced-apart manner on an eccentric circle having the center at a point x2 offset from the center of rotation x1 of a rotary shaft and hence, the brackets can be fixed to the mounting portion formed on the pressure vessel at a predetermined angular position which uses the point x2 offset from the center of rotation x1 of the rotary shaft as the center of rotation.
Abstract:
A coin-shaped battery includes a cathode case (1) having a crimp portion (14) in the periphery of a bottom face (1a), and an anode cap (2) having a flange (6) with an extended portion (7) and a turn-up portion (8). Openings of cathode case (1) and the anode cap (2) are sealed by crimping with a gasket (3) interposed therebetween, so that the gasket (3) is compressed between the crimp portion (14) having a U-shaped cross section, the flange (6), the extended portion (7) and the turn-up portion (8) to effect reliable sealing. Thus, it is possible to disperse a deformation pressure, which is generated by bulge of the cathode case (1) and the anode cap (2) caused with a rise in internal pressure of the battery under severe working conditions such as use under a high temperature. As a result, the coin-shaped battery having improved liquid leakage resistance in the crimped portion is provided.
Abstract:
An electronic circuit including a plurality of D/A converters is operated to provide uniform outputs from the D/A converters even if the D/A converters have different levels of offset values by providing each D/A converter with a memory for offset correction digital data and an adder for adding the offset correction digital data to a digital input signal to the D/A converter. The uniformized outputs from the A/D converters may be used for providing a uniform display on a liquid crystal display apparatus. The liquid crystal apparatus may be provided with a pair of common signal lines for separately supplying positive polarity-picture signals and negative-polarity picture signals to an active matrix substrate for driving the liquid crystal.

These cells thus joined together are inserted into and held within a frame body formed in one-piece with a pair of end face covers, connecting bar, and retaining piece, or alternatively, inserted into and held within a cell casing having a pair of end face covers, bottom wall, and partition boss formed integrally therewith.
Abstract:
A voltage-controlled oscillator is constructed to greatly reduce the number of parts required, its overall size, and manufacturing cost. The voltage-controlled oscillator includes first and second resonance circuits, first and second oscillation circuits, a buffer circuit amplifying the oscillation signals output from the first and second oscillation circuits, and an output-matching circuit. In addition, the voltage-controlled oscillator includes a first switching circuit for controlling the oscillation of the first oscillation circuit and a second switching circuit for controlling the oscillation of the second oscillation circuit. The impedance changing of the matching circuit is simultaneously performed while switching between the switching circuits.

In a circuit that controls the mean current flowing to a load 40 by turning ON or OFF in predetermined ratio the power source voltage VB applied to load 40 using for this purpose a switch means Sw1, a capacitor C1 is charged with the potential difference generated between the load 40 and power source whilst switch means Sw1 is OFF, and a voltage for control purposes which exceeds power source voltage VB is applied to drive circuit 20 using this stored voltage. A high side switch can thereby be implemented using N type semiconductor elements in a simple circuit.
