IPC: G11B15/44
Filed: 1986-12-19
Abstract: PURPOSE:To simplify a rotating mechanism and to reduce its cost by composing a drive gear for rotating a feed reel base by which reciprocal rotation of a tape is transmitted. CONSTITUTION:By rotating a motor 12 clockwise, a fly wheel 7, movable member 8 and feed reel base 11 are rotated and the drive is turned into the fast forward operation, whereas by rotating the motor unticlockwise to make the reel base 11 reverse, the drive is then changed for the rewinding operation.

Title: Non-linear da converting circuit
Inventor: KAWAI KIYOSHI
IPC: H03M1/66
Filed: 1987-11-30
Abstract: PURPOSE:To obtain an analog signal to be non-linearly changed to the linear change of an input digital signal by returning an analog output signal to a waveform shaping circuit, integrating it and converting it to analog quantity. CONSTITUTION:Since the voltage of the connecting point of two resistances R10 and R11 is regularly returned through a resistance R12 to the emitter of a second transistor Q2 in the output step of a waveform shaping circuit 1, the bias voltage of the emitter of the second transistor Q2 is caused to pressurerise in correspondence to an output. Accordingly, the collector voltage of the second transistor Q2, namely, the output voltage of the waveform shaping circuit 1 goes to be high only by the voltage of a V1 and a pulse voltage goes to be a V2. Then, this pulse voltage is integrated by a signal converting circuit 2 and converted to the analog quantity. Thus, when the duty ratio of the pulse of the input digital signal is caused to be linearly large, the output voltage from an output terminal O is non-linearly changed so as to be gradually increased as the duty ratio goes to be large to the linear change which is shown by a broken line.

Title: Leaked solution detecting device
Inventor: KOBORI TAMOTSU
IPC: G08B29/14
Filed: 1988-11-30
Abstract: PURPOSE:To confirm the soundness of the title device in an ordinary using state by diagnosing the operating state of the device in such a way that a voltage for diagnosis is read under an ordinary leaked solution detecting condition and whether the value is normal or not is discriminated. CONSTITUTION:A voltage conversion circuit 2 converts the electric resistance of a leaked solution detecting sensor 1 into a DC voltage and a diagnosing voltage generation circuit 3 generates a DC voltage for diagnosis by connecting a dummy resistance to the circuit 2. An A/D-converting means 4 converts output voltages of the circuits 2 and 3 into digital data and a liquid leaking state discriminating means 5 discriminates a liquid leaking state by comparing the voltage data of the circuit 2 with reference data in magnitude. Since the electric resistance value of the sensor 1 drops when a non-insulating liquid exists, it is discriminated that the resistance value drops from a fixed value from the comparison of the voltage data. An abnormal state discriminating means 6 discriminates an abnormal state from the difference between the voltage data obtained through the AD-converting means and the reference voltage data.

Title: Digital reception equipment
Inventor: KATO HISAYA
IPC: H04L27/227
Filed: 1993-12-06
Abstract: PURPOSE:To enable reception with fast synchronism by detecting the level of a received signal by using a level detector, judging the frequency synchronism between the carrier of the received signal and a regenerated carrier, and varying a step range of sweeping and synchronizing the frequencies unless the carriers synchronize with each other. CONSTITUTION:A comparing circuit compares the level value from the level detector with the level value obtained when the frequency of the carrier of the received signal of an orthogonal detector synchronizes with the frequency of an oscillator. Then a DELTAF setting circuit 902 sets the step range of sweeping, carried out until the level values match each other, as DELTAF1. Once the level values match each other, the DELTAF setting circuit 901 sets a step range of tracking, performed until the phase error between the carrier of the received signal of the orthogonal detector and oscillator becomes zero according to a phase error signal. Further, an up/down counter 903 increases or decreases the calculated value of the step range DELTAF. Lastly, this calculated value is calculated by addition or subtraction from the phase error signal to control the oscillation frequency and phase.
