Title: Photo coupler circuit
Inventor: MATSUI TOSHIO
IPC: H01L31/167
Filed: 1982-09-14
Abstract: PURPOSE:To shorten off-time by releasing the state of overdrive by a method wherein the current flowing into the light emitting diode of one photo coupler is reduced by using two photo couplers. CONSTITUTION:The photo coupler 1 consists of a light emitting diode 2 and a photo receiving transistor (Tr) 3. The photo coupler 11 consists of a light emitting diode 12 and a photo receiving Tr13. The collector of the Tr3 is connected to the diode 12. When a high level is given to an input signal, a current flows into the diode 2 through resistor r1 and r2, resulting in light emission, and accordingly the Tr3 turns on. Then, the current flows into the diode 12, resulting it light emission, and accordingly the Tr13 turns on. Since the current flows through the resistors r1 and r3, the current of the diode 2 is partially shunted and then reduced.

Title: State sensor, state sensor device and data recording and reproducing device
Inventor: SHIMIZU KAZUYUKI
IPC: G01P15/135
Filed: 1994-07-14
Abstract: PURPOSE:To prevent the malfunction of a state device by detecting that the device is in an unstable condition. CONSTITUTION:When the state sensor 1 is in a stable condition, a conductive ball body 2 enclosed in the cavity of the state sensor 1 short-circuits the electrodes A, G, so that a terminal 3A becomes to be at a low level. When the state sensor 1 becomes to be in an unstable state by its movement, etc., the ball body 2 rolls and the short-circuit condition between the electrodes A and G is instantaneously released, and a narrower pulse is output from the terminal 3A, so that the movement of the state sensor 1 can be detected. When the state sensor 1 falls down, the ball body 2 floats, and the short-circuit condition between the electrodes A and G is released for a time longer than the above, and a wider pulse is output from the terminal 3A, so that the falling- down of the state sensor 1 can be detected. By mounting the state sensor 1 in a magnetic disc device or the like, an unstable condition of the device can be detected, and the precaution against the malfunction of the device can be previously taken before a shock or the like is caused.
