Title: Pcm signal transmitter and receiver
Inventor: NAKAJIMA HAJIME
IPC: H04B14/04
Filed: 1984-01-27
Abstract: PURPOSE:To attain transmission/reception of PCM signals of each channel in serial with high efficiency by performing the data compression of the PCM signal and therefore decreasing the total number of bits. CONSTITUTION:Channels 1-m are provided to a PCm transmitter, and each channel is provided with a differential calculating circuit 1, zero suppression circuits 2 and 3 and a signal switching circuit 4. The circuit 1 is calculates the differential between the PCM signals transmitted at the preceding time and this time. Then 1 and 0 are added to the highest digit of the circuit 2 when said differential is positive and negative respectively. In case zeros are continuous at the circuit 2, the upper digits are suppressed. Then the digits lower than the digit where 1 appears first are delivered. The same procedure is carried out also in case zeros are continuous at upper digits of an input signal at the circuit 3. The outputs of these circuits 2 and 3 are switched by the circuit 4 and processed by a signal synthesizing circuit 5. Then data are compressed. Thus it is possible to transmite and receive the PCM signals of each channel serially and with high efficiency.

Title: Electronic watch with alarm
Inventor: ISHIDA TAKASHI
IPC: G04C23/02
Filed: 1979-02-09
Abstract: PURPOSE: To realize an alarm watch with nearly the same constitution as the conventional watch for the electronic watch featuring the hand display, by processing the alarm function through the electronic circuit and without using any mechanical contact or the like.  
     CONSTITUTION: Operation unit 18 is operated for setting of the alarm, and thus the signals to give the quick sending to step motor 4 are transmitted from control circuit 10. Thus the alarm time is displayed to display unit 5, and at the same time the time difference to the present time is memorized in time difference counter 11. When unit 18 is operated again, the signals to give the reverse quick sending to motor 4 are transmitted from circuit 10. At the same time, display difference counter 15 counts these signals continuously until coincidence 17 is obtained with the contents of counter 11 to return display 5 to the present time. After this, counter 11 receives the subtraction via the normal hand movement signals of motor 4. And when the contents of counter 11 becomes 0, alarm 9 is generated. At the same time, another alarm time is set to time difference counter 12.

Title: Method and apparatus for orthogonal frequency division multiplex modulation system transmission band varying
Inventor: MIYASHITA ATSUSHI
IPC: H04L27/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a transmission system, which automatically follows a change on a reception side by varying a band by means of changing the number of carriers on a transmission side. SOLUTION: A band variable modulation device 101 changes the number of carriers so that a signal becomes a used band width. A frequency conversion transmission device 102 controls a local oscillating frequency so that the signal becomes the used frequency. A transmission signal which becomes the used frequency/band width is transmitted to a reception side. On the reception side, a band variable demodulation device 104 discriminates among a state where all carriers do not exist, a state only a part of carriers exists, and a state where most scheduled carriers exist, outputs a corresponding switch control signal to a frequency conversion reception device 103, switches a received frequency with the switch control signal, and receives the transmission signal from the transmission side.  Thus, the system which automatically searches an idle channel and transmits data with transmission bandwidth corresponding to the idle band is configured.

Filed: 1986-01-27
Abstract: PURPOSE:To always detect a fault generated in a reproducing signal even when the rotation cycle of a disk is slow without being affected by the cycle of the reproducing signal by discriminating a state transition between, for example, two kinds of pulse trains generated from the same reproducing signal. CONSTITUTION:The first waveform arranging means 101, and the second waveform arranging means 102 convert the reproducing signal to square wave signals respectively with different threshold values. A pulse conversion means 103 receives the outputs of the first and the second waveform arranging means 101 and 102, and converts them to the pulse trains which are overlapped sectionally on a time base respectively. The pulse conversion means 103 and a state transition discriminating means 104 are constituted of asynchronous logic, and as a time factor to control these logical states, only a gate delay time generated in a NOR circuit, a buffer, or an inverter is considered, and it has no connection with the cycle of an input signal A. In this way, it is possible to detect the defective place on the disk faithfully without being affected by the rotation cycle of the disk.

Filed: 1990-01-24
Abstract: PURPOSE:To improve constant speed control of a motor by providing means for relatively decreasing the proportional control component of a feedback control signal for the motor when a judgment is made that the rotational speed of the motor is reached to a steady region. CONSTITUTION:A control section 14 calculates a proportional control voltage (V1) every time when a rotational speed for control is determined, and thus calculated voltage is stored. The state of steady region flag is then judged and the steady region flag is reset, and if the rotational speed of a motor 10 is in a transient response region, a proportional control voltage (V2) is calculated. The proportional control voltages V1 and V2 are then added and a control voltage is calculated. Since the ratio of proportional control component in the control signal is relatively low, a stable constant speed control having excellent follow-up performance to variation of load can be realized.
