Title: Automatic exposure control circuit
Inventor: HOSODA SEIICHI
IPC: G03B7/083
Filed: 1980-06-30
Abstract: PURPOSE:To prevent the influence of an exposure time setting switch by presetting the charging voltage of an integrated capacitor of a photodetecting signal integrator by way of a presetting circuit to which the source boltages divided by switches are applied. CONSTITUTION:The divided source voltages by exposure constant setting switches 30-34 are applied to a presetting circuit 22, and the charging voltage of the integrating capacitor 4 of an integrator 5 which integrates the photodetecting value of a photodetector 2 is preset. Thereby, the exposure time constant of the integrator 5 is set, and the exposure is automatically controlled accord the setting by a comparator 6 and the like. Since the source voltages are held applied to the exposure time constant switches despite the formation of oxide films by this system of substantially changing the integration time constants by changing the precharging voltage of the integrating capacitor, virtually no influence thereof is received and contact defects do not occur. The voltage dividing circuit can be of a low impendance and therefore there is no influence of leak current, and the automatic exposure control circuit having no influence of the setting switches is obtained.

Title: Operation control method for variable capacity type air conditioner
Inventor: YAMAZAKI MASAYA
IPC: F24F11/02
Filed: 1985-04-26
Abstract: PURPOSE:To prevent an overheating of compressor even when the upper current level limit for the compressor operation is raised and save energy by modulating the upper limit current for compressor operation so it may be made smaller in stages in response to the ambient temperature. CONSTITUTION:When an overloading condition is encountered in that the compressor operating current IRE detected by a current sensor 12 exceeds the compressor operation upper limit current IA preset in the CPU11, the operation frequency of the compressor is reduced to reduce the operating current. Even when the cooling/heating ratio becomes large, it is not that the operation upper limit current is raised uniformly, but the operation upper limit current is raised only when the ambient temperature is low. Therefore, when the heating mode is assumed, the operation upper limit current can be set low to allow the operation frequency to be reduced even if the ambient temperature is high, and so, the compressor can be run at a higher frequency, preventing the compressor from being overheated. In this instance, since the ambient temperature is high even though the operation frequency is set low, an adequate heating capacity can be secured, and there will practically be no problem.

Title: Character signal generation circuit
Inventor: KIMURA KATSUMI
IPC: H04N5/278
Filed: 1989-04-11
Abstract: PURPOSE:To insert a character even to the variable speed reproducing signal of a VTR without accompanying by perpendicular fluctuation by using a vertical blanking signal as a vertical synchronizing signal, and a signal generated at a phase locked loop as a horizontal synchronizing signal. CONSTITUTION:The vertical blanking signal V-BLK generated from the rotary phase detecting pulse of a rotary head drum in a video tape recorder is used as the vertical synchronizing signal, and also, the signal generated at the phase locked loop(PLL) 9 in which the horizontal synchronizing signal of a reproducing video signal is set as phase reference is used as the horizontal synchronizing signal. Thus, the vertical blanking signal V-BLK generated from a PG pulse is used as the vertical synchronizing signal. Thereby, a stable vertical synchronizing signal can be obtained without missing. Also, since the signal generated at the PLL circuit 9 where the horizontal synchronizing signal SYNC of the reproducing video signal is set as the phase reference is used as the horizontal synchronizing signal, the signal with a constant cycle can be obtained by the PLL circuit even when disturbance due to missing exists in the horizontal synchronizing signal SYNC.

Filed: 1988-04-12
Abstract: PURPOSE:To obtain a binary signal with stable duty ratio by applying a pulse from a decoder circuit to an amplitude limiter only when a received electric field is a prescribed value or above and an AC component of a prescribed level or above exists in a demodulation signal. CONSTITUTION:A detection circuit 12 detects the presence of a received electric field, the detected output is inputted to a comparator 13 and compared with a reference voltage. Moreover, an AC detection circuit 16 detects the presence of the AC component in a base band signal outputted from a low pass filter 8, the detected output is inputted to a comparator 17 and compared with a reference voltage 18.

Title: Control of servo motor
Inventor: KAMIMURA HIDEYUKI
IPC: H02P29/00
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To eliminate an excessive force to be applied to a drive system by a servo motor and prevent uncontrolled rotation by setting a motor speed command limit value to the value obtained by adding a constant margin to the rated command voltage value of a servo motor. SOLUTION: For each movement of a movable head, a controller 100 writes a voltage value obtained by adding a constant margin to the rated command voltage values of the servo motors 26a, 27a, 34a, 27b, 27c, 27d into 4-wheel motor controllers 101, 102 as a motor speed command limit. Thereby, when an over load condition is generated and when a speed command value exceeding the individual motor speed command limit value is input, a servo motor stops momentarily. Therefore, since even if an over load is added, the servo motor does not rotate forcibly by means of the servo control and each drive section is not broken and moreover the servo motor does not rotate uncontrollably even if a load is suddenly reduced.
