Title: Communication terminal device for document preparation
Inventor: YAMADA TOSHIAKI
IPC: H04L29/12
Filed: 1982-02-22
Abstract: PURPOSE:To keep received document information without discarding the information, by controlling the whole system in a document preparating terminal device provided with a document preparation editing function and a communicating function by a system controlling part. CONSTITUTION:When the received document information is stored in a communication controlling part 5, receiving information indicating the storage of said information is outputted to the system controlling part 9. The system controlling part 9 discriminates whether a printer 3 or an external storage part 4 is ready or not. The output of the received document information when any one of the devices is ready and the holding of received document information when both of them are unusable are commanded to the communication controlling part 5, which executes processing in accordance with these commands. Thus the document information can be kept even if both of the printer 3 and the external storage part 4 are unusable.

Abstract: PURPOSE:To maintain the engaging force of lock-up suitably for vehicle speed condition, by comparing between the governor pressure and a fixed level pressure, and as well by using the higher one of both pressures as the control index of the engaging force of a direct coupling clutch. CONSTITUTION:When the vehicle speed raises so that a speed change ratio in the intermediate stage is established, a timing valve Tv moves leftward to take a second switching position, and therefore, an oil passage 95 is communicated with an oil passage 83. As a result, hydraulic pressure let from a high select valve Vs to a second pilot chamber 99 in a modulator valve Mv, is set to either one of the governor pressure Pg and the lubrication oil pressure Pu, which is larger than the other, and the hydraulic pressure which is an increased value of the larger one of the pressures is used as the output hydraulic pressure of the modulator valve Mv or the working hydraulic pressure of a direct coupling clutch Cd. By suitable selecting the degree of the lubrication hydraulic pressure Pu, the lock-up of the direct coupling clutch may be maintained even upon running at a speed lower than the lock-up vehicle speed.

Title: Disk record reproducer
Inventor: MAEDA SATORU
IPC: G11B7/085
Filed: 1983-02-21
Abstract: PURPOSE:To stop quickly the movement of a pickup when a track jump is over and to apply the tracking servo by compensating the level of the DC offset voltage of the tracking error signal after detecting the unbalance of irradiated areas between two detection regions where detectors are divided in the pit train direction. CONSTITUTION:When an objective lens is deflected to the plus and minus sides, the reflected light of a disk is irradiated with no balance to two detection regions PDa and PDd as well as PDb and PDc. Thus the voltage difference between DC voltage signals Va and Vb is extracted in the form of (Va-Vb), and therefore the tracking error compensation signal DELTAT is turned into a voltage signal having the polarity opposite to the DC offset voltage generated in the tracking error signal T. Then the same peak value is set between the positive and negative voltages, and therefore the two control regins are always set equal to each other for the tracking error signal (T+DELTAT) which is delivered to a tracking servo circuit 23. Thus it is possible to lead accurately a spot into a desired pit train when a searching operation is over.

Abstract: PURPOSE:To make it possible to maintain the actual value of an exciting voltage at a target value by detecting the exciting voltage, and adjusting the exciting voltage based on the detected signal. CONSTITUTION:An AC input current is converted. into DC with a rectifying and smoothing circuit 16. The voltage of the rectified and smoothed output is adjusted with a voltage adjusting and switching circuit 20. Then, the voltage is supplied into the exciting coil of an electromagnet 14. The exciting voltage applied to the electromagnet l4 is detected with a voltage detecting circuit 22 and utilized for generating a voltage control signal for controlling the voltage in a signal processing circuit 24. Therefore, the actual value of the voltage applied to the electromagnet 14 is utilized for the voltage adjustment in the voltage adjusting and switching circuit 20. The voltage is maintained at the target value of the voltage. When demagnetization is performed with the electromagnet 14, a switching control signal is supplied into the voltage adjusting and switching circuit 20. Thus, the effect of the voltage fluctuation in the input power supply is minimized, and the output voltage is stabilized over the broad range. The apparatus can be used without changing the characteristics of the voltage detecting circuit even for the electromagnet whose rated current is largely different.
