Title: Lighting device for emergency
Inventor: SUZUKI HIROSHI
IPC: H02M7/48
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a lighting device for emergency capable of making rectified and filtered voltage constant with a simple structure in a case where a voltage value of an a.c. power source is higher than a prescribed value. SOLUTION: When a commercial a.c. power source e has voltage higher than a prescribed voltage, a Zener diode ZD11 is turned on and the base of a transistor Q11 becomes at L level, so that a battery B is charged through a resistor R3 and a diode D11. A constant voltage circuit is constituted of the transistor Q11 and the Zener diode Z11 to make the charging voltage of the battery B constant without ripples. In a case where a voltage of the commercial a.c power source e is lower than a prescribed voltage, d.c. power source of the battery B is supplied to an inverter circuit 4 to light a fluorescent lamp by high frequency.  A charge of the battery B is efficiently used for the inverter circuit 4 by keeping the state of a switching circuit 11 by turning transistors Q11, Q12 off without using the charge of the battery B, so that the discharging characteristic can be stabilized and the discharging duration of the battery B is kept long while lowering the electric power consumption.

Abstract: PURPOSE:To convert a readout/write speed of the titled circuit to a high speed, and also to make its constitution simple and small in size by providing a readout/write switch on an input side of an inverter for forming a sense amplifier. CONSTITUTION:Switches S1, S2 which have been provided on input sides of inverters I1, I2 which are connected to a pair of bit lines 11, 12 respectively and form a sense amplifier are controlled by a signal from a control signal terminal, and readout of a RAM is executed through data output terminals 17, 18. This readout is executed at a high speed since the switches S1, S2 are provided on the input sides whose parasitic capacity is small and which are not influenced by an on-resistance, and the time constant is small. In the same way, input data from terminals 13, 14 are amplified by the sense amplifier through switches S3, S4 and written at a high speed on the RAM. According to them, a readout/write speed is converted to a high speed, and also a write amplifier is not required, and the constitution becomes simple and small in size.

Abstract: PURPOSE:To reduce the cost, to make the performance stable and to facilitate the adjustment by coating the reflection film of split prisms simultaneously. CONSTITUTION:A split prism 18 having a 1st reflecting face and a 2nd reflecting face forming the image of the reflected beam separately from a recording medium 7 and a photodetector 13 placed along the optical path of both the separated reflecting beams are provided to the device.

IPC: H01J29/48
Filed: 1981-06-03
Abstract: PURPOSE:To provide a cathode-ray tube which forms a long spot deformed perpendicularly to the scanning direction upon a picture surface, and which can correct not only the inclination of the spot caused when electron beams are deflected toward the peripheral part of the picture surface but also the distortion of the spot itself. CONSTITUTION:A first magnetic tetrode 20, which is used for correcting the inclination of a beam spot at the peripheral part of the picture surface of a CRT1, is installed at a neck 2 of the CRT1, for example, near the position of the Z-axis direction of a third grid electrode 8. On the other hand, a second magnetic tetrode 30, which is used for correcting an S-shaped distortion of the above beam spot, is installed near the back end of the Z-axis direction of a deflecting part 15, for example, in the space formed between the back end of a vertical deflection coil 16 and the back end of a horizontal deflection coil 17. Therefore, when this is applied to, especially, a beam-indexing CRT which has not any aperture grill or shadow mask, the beam spot is securely included by a fluorescent stripe corresponding to a display cell formed on a fluorescent screen. As a result, the quality of the picture can be increased by preventing any deterioration of the color purity and the resolution.

IPC: H03K17/66
Filed: 1989-04-06
Abstract: PURPOSE:To speed up the turning-off operation of transistors(TRs) and to attain efficient switching operation by forming a ternary winding on a transformer and using a DC bias obtained by rectifying the output of the ternary winding as a power supply for turning off a switching TR. CONSTITUTION:When a TR 41 is turned on and a TR 42 is turned off, a switching TR 3 is turned on, the voltage of the shown polarity appears on the ternary winding N3 of the transformer 2' and a capacitor 6 is charged with electricity by the shown polarity through a diode 5. At the time, the voltage of the capacitor 6 is applied between the emitter of the TR 3 and the reference potential point (a) of a driving circuit 4. When the TR 42 is turned on and the TR 41 is turned off, the base charge of the TR 3 is discharged through the TR 42 and the voltage of the capacitor 6 is reversely applied between the base and emitter of the TR 3 to turn off the TR 3. Since the TR 3 is driven so that reverse bias voltage is applied between the base emitter of the TR 3, the accumulation time of the TR 3 can be shortened and the turning-off operation of the TRs can be quickly executed.
