Title: Diaphragm driving device of camera
Inventor: HARADA TOSHIMITSU
IPC: G03B9/07
Filed: 1981-02-09
Abstract: PURPOSE:To minimize the impact produced when the diaphragm drive is stopped, by securing a constitution in which the hooking of a diaphragm drive member is released when the releasing action is carried out while a charge member is rolled up and hooked and the diaphragm drive member has a going action by the going energy given by the charge member. CONSTITUTION:A diaphragm drive member 9 coupling to a diaphragm device is rotatably supported around the optical axis by means of a roller 11. A hooking pin 12a implanted to a plate spring 12 is engaged with a hooking hole 9b of the member 9. When the film is advanced under such conditions, a charge lever 14 is turned right by a film advance lever 13 to charge a drive spring 17 via the member 9. At the same time, a resetting spring 18 provided between a camera main body 3 and the spring 17 is charged to complete the film advancing action. Both springs 17 and 18 are charged by the film advancing action, and no offset is caused between the energizing powers of both springs to obtain the minimum necessary spring constant.

A balanced voltage is applied to a load RL from output electrodes 5 and 6, and the load is floated from the earth. A current detection circuit 8 comprised of a resistor R2b, a capacitor C and a diode D is provided to the input electrode 2b to detect a load current io. Since the load current io is shouted to the input electrodes 3a and 2a and input electrodes 3b and 2b, it can be detected by using the voltage drop of the resistor R2b. As being different from the case where the circuit 8 is provided to the load RL side, no large floating capacitance is generated in the load RL and leak current can be reduced greatly.

Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To prevent electrification unevenness and to always obtain an optimum image by estimating the soiled state of an electrifying member, for changing the cleaning interval of the electrifying member with a cleaning member. SOLUTION: An electrifying roller 3 as the electrifying member in contact with a photoreceptor drum 2 as an image carrier, for electrifying it is arranged and the cleaning member 1 is pressed on the electrifying roller 3. As cleaning sequence, the number of the operation times of the cleaning member 1 is changed with a cumulative use frequency for copying as the number of image forming times from the new use start, of a drum cartridge.  In other words, the cleaning member 1 is operated by a copying operation after the power of a copying machine main body is turned on, to clean the electrifying roller 3; the cleaning member 1 is operated every time all copies are made, when the cumulative number of the copies is up to 20 sheets, because fine powder from a cleaning blade is easily stuck to the photoreceptor drum 2, every time three copies are made, when the cumulative number of the copies is up to 50 sheets and every time two copies are made, when the cumulative number of the copies is up to 100 sheets. Thus, after the drum cartridge is exchanged, the cleaning interval of the electrifying roller 3 by the cleaning member 1 is made smaller as the number of the copies is smaller.

Filed: 1992-02-04
Abstract: PURPOSE:To prevent the discharge of a rocket or a satellite or the like and to simplify the procedure when a high power RF signal is switched in a pressure zone in which the rocket or satellite is easily discharged. CONSTITUTION:A voltage is applied to a base of a transistor(TR) 5 only when a command signal S is inputted between terminals (A) and (C) or between terminals (B) and (C) of a coaxial switch 1, an RF signal is fed to a circulator 2, a capacitor 3 and the TR 5 to a resistor 6 to interrupt the input to the coaxial switch 1. On the other hand, the changeover of the coaxial switch 1 switch 1 is finished in a time when the command signal S is applied thereto. Since no RF high power is applied to the coaxial switch 1 during the changeover operation, it is not possible to damage the coaxial switch 1 and not required to interrupt the RF signal at the changeover.

Title: Power supply device
Inventor: SUZUKI HIROSHI
IPC: H02M7/48
Filed: 1994-02-15
Abstract: PURPOSE:To make a power supply device small and light while taking out a big load current by removing high frequency components from a high-frequency rectangular wave having constant amplitude and a modulated pulse width appeared on both sides of a serial circuit by a low-pass filter together with taking-out output voltage of a low frequency or DC, or synthetic output voltage of a low frequency and DC. CONSTITUTION:A DC circuit 5 is turned OFF when voltage Vsb is smaller than Zener voltage and at this time the voltage, where voltage Vc2 of a capacitor C2 is added to voltage Vsb, is impressed across the DC circuits 5. Accordingly, voltage Vsa across the DC circuits 5 becomes rectangular wave voltage having a modulated pulse width. Since a low pass filter 6 removes high-frequency switching components from voltage Vsa, output voltage Vo can be obtained. Thereby, output voltage of a low frequency or resultant output voltage of a low frequency and DC can be obtained to reduce the sized and weight.
