Inventor: SHIMOMURA JUNICHI
IPC: H01L21/322
Filed: 1991-04-11
Abstract: PURPOSE:To manufacture a silicon wafer which reduces a lamination defect caused at a heat treatment during a later process in such a way that it is manufactured easily and economically by a simple heat treatment whose number of processes is small. CONSTITUTION:A heat treatment composed of the following is executed: a silicon wafer after it has been sliced, after it has been lapped or after it has been polished is heated in such a way that it is set and held at a uniform temperature as a whole within a range exceeding 1100 deg.C and less than its melting point; and, after that, it is cooled down to 600 deg.C to room temperature within 10 minutes.

Title: Card reception device
Inventor: MINEO KOUICHI
IPC: G11B19/00
Filed: 1979-06-20
Abstract: PURPOSE:To prevent the card from staying at the area near the card reception slit when the carrier path is opened, by providing the mobile plate so that the upper part of the mobile plate may be nearly parallel to the fixed plate in the state under which the conveyer carries the card. CONSTITUTION:Card reception slit 3 is provided at the upper end area of card reader 1 to accept card 2 inside. When the action of reader 1 stops and then rocks in the direction where mobile plate 6 becomes apart from fixed plate 5, the center part of lever 34 is also shifted in the same direction as the rocking way of plate 6. As a result, lever 34 starts rotations in the energizing direction of spring 36 and continues the rotations until hook part 37 is regulated for its rotation via stopper 38. And the center part continues the shift according to the rocking of plate 6 although the rotation of the other end is regulated. As a result, one end of lever 34 shifts into the opposite direction to the energizing direction of spring 36. Thus reception slit roller 32 is separated from belt 10, and accordingly roller 32 never presses card 2 to belt 10.

Title: Waveform shaping device
Inventor: HORIIKE YOSHIO
IPC: H04L27/14
Filed: 1993-04-06
Abstract: PURPOSE:To remove a spike noise which is characteristic to a frequency demodulation system by interpolating a delayed demodulated signal to a certain value when a spike noise detection signal is present. CONSTITUTION:The frequency-modulated radio wave signal from an antenna 1 is passed through a receiver 2, and a demodulating means 3 imposes frequency demodulation. Only a noise component higher than a data signal is extracted by an HPF 6 from the signal from a demodulation output signal (a) and sent to a spike noise detecting means 7, which detects the spike noise and sends the corresponding pulse to an interpolating means 9. The signal from the terminal (a), on the other hand, is sent to the means 9. The means 9 is controlled with the output pulse signal of the means 7 to outputs the output signal of the means 8 as it is unless there is the pulse signal, but holds the signal level from the means 8 at the time of the generation of the pulse signal when there is the pulse signal. The output signal of the means 9 is sent to a binarization circuit 5 through an LPF 4, binarized with a specific threshold value, and outputted.

Title: Timer apparatus
Inventor: OZAKI HIROYUKI
IPC: H01H43/00
Filed: 1982-05-11
Abstract: PURPOSE:To simplify the change-over of timer operation and a set time by a min. signal even in the case of manipulation due to remote control, by mounting a change-over circuit wherein the operation of a timer circuit is started by a first input signal and the set time of the timer circuit is changed over by the input signal on and after the second one. CONSTITUTION:During the timer operation of a set time NT2, because the output voltage (c) of a transistor 19 is a high level and the output voltage (f) of a flip-flop 20 is also a high level, the transistor 26 of a display circuit 21 comes to an ON state and a light emitting diode 28 is lighted to display such a state that the timer of NT2 is under operation. When a third pulse signal for timer-on. time change-over is again issued before NT2 is elapsed, timer operation is once also switched to NT1 and the timer operation is again started. When timer output (h) is generated after a predetermined time, a relay is changed over while a contact is switched off and the supply of a power source to a television receiver circuit is switched off while a power source to a timer apparatus is blocked to complete timer operation.

Abstract: PURPOSE:To detect the position of an out-lighted light by connecting the light and a voltage detector with a secondary coil of a transformer, connecting a light emitting means to light off when the light is burnt out with the voltage detector, and making a remote indication of this. CONSTITUTION:A lighting means 7 is lighted by a secondary voltage of a voltage detector 6 when a light L is lighted normally. Output voltages of current detecting transformers 10, 11 are equal, therefore DC voltages of diodes D1, D2 are equal, and a TRIAC switch is not continuing. If the light L is lighted out by burning out, a secondary coil S becomes open. Outputs of the transformers 10, 11 disappear by this, and because a discharge time constant C1R1>>C2R2, the voltage of a resistance R2 becomes lower than the voltage of R1 rapidly, and the TRIAC switch continues, while the coil S is closed through a resistance R3. In the meanswhile, the light emitting means 7 changes to a light-out condition, which is indicated remotely at a concentrated monitoring panel 9 by an optical fiber 16.
