Title: On/off operating circuit for field effect transistor
Inventor: KAMIJO HIROSHI
IPC: H03K19/0175
Filed: 1987-04-20
Abstract: PURPOSE:To make a high voltage withstanding transistor unnecessary, by short- circuiting and releasing only voltages generated at both ends of a third circuit element on the side of a reference potential point out of three circuit elements in a voltage division circuit by a first switching circuit. CONSTITUTION:Only the third circuit element 33 on the side of the reference potential point in the voltage division circuit 30 is short-circuited and released by the first switching circuit 10. Therefore, only the both end voltages of the third circuit element 33 at most are applied on a MOS transistor 11 used for the first switching circuit 10. In such a way, it is possible to make the usage of the high pressure tight transistor unnecessary in a gate operation circuit which performs the ON/OFF operation of a field effect transistor, and to improve ratinalization and operating reliability at the time of diversifying an integrated circuit.

Title: Cam device of zoom lens
Inventor: SAWANO HIROSHI
IPC: F16H53/00
Filed: 1978-08-10
Abstract: PURPOSE: To obtain the large optical axis direction movement quantity of the lens group without increasing the pressure angle of a cam by providing the means of letting the lens group retreat along with turning of the cam ring and displacing the cam ring in the optical axis direction.  
     CONSTITUTION: The rear group holding frame 6 and helicoid frame 5 holding a rear group lens L2 are held fitted in the stationary inner barrel part 1c and the front group holding frame 7 holding a front group lens L1 is held screwed into the helicoid frame 5. When the front group lens L1 advances and the rear group lens L2 retreats, the zoom lens system takes a short focal length and is in the state existing on the wide side. When the zoom ring 3 is pulled out forward in the optical axis direction, a cam ring 2 displaces in the optical axis direction, causing the rear group lens L2 to advance and the front group lens L1 to retreat. Then the zoom lens system takes a long focal length and is in the state of existing on the telephoto side. Since the pressure angle of the cam is not increased, the variable power operation may be stably and smoothly accomplished.

Title: Printer
Inventor: MATSUBA HIROYUKI
IPC: B41J7/92
Filed: 1985-05-07
Abstract: PURPOSE:To change the amount of work and obtain printing pressures in multiple stages through a single spring, by providing a controlling member for receiving a falling roller at a predetermined position, when the roller provided at a driving lever falls off a stepped part of a cam to perform a printing action. CONSTITUTION:When reducing a printing pressure, a solenoid 21 is energized, whereby an elastic member 18 is turned counterclockwise through a plunger 21a and a wire 20, and a high stepped part 18a is set to a falling position of a hammer 4. The roller 4 falls from the highest position 1a of the cam 1 to the high stepped position 18a of the member 18, and a hammer head 13a strikes a platen 17 through a type wheel 16. The larger the falling distance of the roller 4 is, the larger the energy supplied from the spring 5 is, the striking force of the hammer 13 is strengthened, and the printing pressure is made higher. The printing pressure is higher or lower as the solenoid is deenergized or energized. Accordinglyh, since the falling roller 4 is received by the elastic member 18, impact sound is markedly reduced.

Title: Exposure quantity controller
Inventor: NAITO YOSHIICHI
IPC: G03G15/04
Filed: 1987-04-20
Abstract: PURPOSE:To prevent normal copying operation from being impeded by correction and its time from becoming long by detecting the visual image density on a photosensitive body in a preprocess or postprocess regarding copying operation for a set quantity of copies. CONSTITUTION:A control means D obtains original density and visual image density supplied from respective detecting means A and B and varies the set value of a proper lamp voltage for the original density according to the visual image density and the value of the lamp voltage when the density is measured. The control means D, on the other hand, detects the visual image density on the photosensitive body F by the visual image density detecting means B in the preprocess or postprocess regarding the image formation for a set quantity of images. Therefore, corrections neither impedes normal copying operation nor makes the normal copying operation time long. Consequently, invariably proper image reproducibility is secured without reference to the normal image forming operation nor time however the conditions change on the original side and image forming device side.

IPC: H02P9/04
Filed: 1993-04-23
Abstract: PURPOSE:To make it possible to shorten the time period from load break to steady operation by controlling set values by digital operation and switching set values without performing set value operations at load break. CONSTITUTION:A speed set value operation unit 11 performs operations of speed set values in a specified sampling cycle according to the commands to increase or decrease the set values.
