Title: Data multiplex broadcast receiver
Inventor: NISHIKAWA KEIICHI
IPC: H04N5/445
Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To provide a data multiplex broadcast receiver which can reduce its power consumption by cutting the supply of power at least to a tuner part, a data signal detection part or an error correction part until the next new data group transmission time passes. SOLUTION: In a normal reception mode, a processing part 7 is not required to receive the retransmission as long as the same data group identification code is available and the data group continuous transmission codes are increased. Thus, the time covering up to the next application of a power supply is inputted to a timer part 8 since no operation is needed for a tuner part 2, a data signal detection part 3 and an error correction part 4 during the time that is calculated from the data group size. The part 8 cuts the supply of power to the parts 2 to 4 based on the inputted time. In such a constitution of a data multiplex broadcast receiver, the transmission time of the next data group header is calculated from the current broadcast format. Then the supply of power is cut to the unnecessary parts 2 to 4 during the calculated transmission time.  As a result, the power consumption is reduced and accordingly the exhaustion of a battery can be suppressed.

Filed: 1987-09-03
Abstract: PURPOSE:To enable detecting the number of revolutions of a motor in non- contact manner and with good accuracy by taking out and counting current variation components generated from the current signal of a DC motor with switching of the direction of current of a coil. CONSTITUTION:The current detection signal of a motor 1 detected by a current detecting element 2 is given to a band-pass filter 6 via an amplifier 5.

Then, a counter 8 counts the output frequency signal of the band pass filter 6 to output a revolution signal. Thus, the number of revolutions of a motor can be detected in non-contact manner and with good accuracy.

Title: Take-up speed control system of magnetic tape device
Inventor: FURUHATA SHIGEYUKI
IPC: B65H18/10
Filed: 1983-11-28
Abstract: PURPOSE:To shorten the tape take-up time with no increase of the voltage of re el motors nor improvement of their characteristics, by detecting the tape feed length, the number of revolutions of a supply reel motor and the diameters of both supply and take-up reels respectively. CONSTITUTION:The speed control of reel motors 8 and 9 is carried out to set the position of a tape loop within a vacuum column within a fixed range after detecting the position of the tape. The revolving directions of those motors are detected by a detection circuit 17 and with the output of a tachometer 14 of a capstan motor 3. While the length of a tape 7 fed forward is measured by an arithmetic circuit 18. The diameter of a supply reel 1 is obtained from the numbers of revolutions of the motor 3 and a take-up reel 2 and the diameter of the capstan 3. The diameter of the reel 2 is stored by the circuit 18, and the tape speed is increased until the coincidence is obtained between diameters of reels 1 and 2. Then the tape speed is slowed down to a level decided by the diameter of the reel 2. Thus it is possible to shorten the tape take-up time without increasing the voltage applied to reel motors or improving the characteristics of these motors.

Title: Switching power unit
Inventor: TAKAHASHI TSUTOMU
IPC: H02M7/12
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent the output power of a switching power unit from becoming excessively large and, at the same time, to prevent the ASO-breakdown of a switching element by providing an input voltage waveform shaping means which cuts off the part of an input voltage exceeding a prescribed voltage value between an AC power source and an active filter. SOLUTION: A Zener diode 30 is provided between an AC power source 1 and an active filter 20 so as to cut off the part of the voltage applied to a voltage dividing resistor 4 exceeding the Zener diode of the diode 30. Therefore, the output power of a switching power unit can be limited, because the filter 20 suppresses the peak of the input current I1 of the power unit so that the current I1 can become proportional to the input voltage of the power unit. In addition, the ASO-breakdown of a switching element 21 can be prevented, because the electric current I2 flowing to the element 21 is prevented from becoming excessively large.
