Abstract: PURPOSE:To improve a strength while maintaining the miniaturization of a mechanism and the simplification of a composition by driving an arm via the gear line consisting of plural gears to be driven by a driving means and varying the tooth profile of this gear according to the load impressed on each gear. CONSTITUTION:The module of each gear 20-23 is taken of the shape corresponding to the load impressed on the tooth root of each gear part 27-32 and the displacement of a roller 20a is amplified by using the gears 20-23.

Filed: 1987-07-24
Abstract: PURPOSE:To effectively cancel an echo signal by assuming the reverberation time of an echo path with an initial training signal and variably setting a tap length in order to generate a pseudo echo signal in accordance with the reververating time. CONSTITUTION:A learning circuit 4 inputs the initial training signal outputted from a training circuit 3 and assumes the echo path characteristics of the echo path formed by an acoustical coupling between a speaker 1 and a microphone 2 in the form of an impulse response. A coefficient multiplier 6 multiplies each tap output of a tap delay line 5 by a tap coefficient, which constitutes the echo characteristics assumed at the learning circuit 4, and executes tap- coefficient-processing. An adder 7 adds each tap-coefficient-processed tap output and generates the pseudo echo signal. The pseudo echo signal is given to a subtracter 8 and the cancellation of the echo signal contained in an input sound signal is executed.

Abstract: PURPOSE:To easily remove a photoreceptor with a simple structure by rotating a magnet enclosed in a photoreceptor drum, moving it to the position where the magnetic pole is never opposed to a toner hopper and a recovering roller, and then removing the photoreceptor drum. CONSTITUTION:When a photoreceptor drum 1 is separated from a toner hopper 6, a magnet 2 is rotated, and moved to the position B where the magnetic pole of the magnet 2 is never opposed to the toner hopper 6 and a recovering roller 8, and the photoreceptor drum 1 is then removed. Namely, at non- operation, the magnet 2 is moved to the peripheral area of the photoreceptor 1 where no magnetic toner 7 is present, or the position B. Thus, the toner 7 is never adhered to the photoreceptor 1 even when the photoreceptor 1 is removed from the toner hopper 6. The magnet 2 may be moved so that the magnet 2 is situated in the position B when a developing device is not operated, and automatically moved from the position B to the position A only when the developing device is operated.

Title: Menu display selection system
Inventor: TAKANO AKIRA
IPC: G06F3/0482
Filed: 1987-07-23
Abstract: PURPOSE:To ensure the selection of any item in a menu with an equal shift distance of a cursor by detecting a selected item based on the selection instructing angle and the moving direction of a pointing device PD. CONSTITUTION:A cursor 6 is shifted by a PD4 and points a position where a menu is displayed.

This menu 71 is displayed on a display 3 by the indication of the PD4. Then the cursor 6 is shifted by the PD4 in the desired direction of the menu 71 shown on the display 3. Thus a desired item is pointed. Then the moving direction of the cursor 6 is detected by an angle detecting part 51. As a result, a men item OP8 is selected in response to the moving direction of the cursor 6.

Title: Developing device
Inventor: SAITO TETSUO
IPC: G03G15/08
Filed: 1990-07-13
Abstract: PURPOSE:To prevent the occurrence of the rising phenomenon of an initial density and to attain reduction in the stirring torque of a developer by providing opening parts on stirring members. CONSTITUTION:Plural slit-like opening parts 8a are formed in longitudinal directions (shaft directions) at a prescribed pitch, on respective stirring members 8. Therefore, when the developer 7 is carried from a developer container part to a developing part by the stirring members 8, the developer 7 passes through the opening parts 8a formed on the stirring members 8 and is leaked. Thus, the developer 7 having tribo is not excessively fed into the developing part, but the reduction in the tribo around a developing sleeve 4 can be prevented, so that the rising phenomenon of the initial density can be effectively prevented. On the other hand, the developer 7 passes through the opening parts 8a and is leaked, so that the resistance pressing force of the developer 7 with respect to the stirring members 8 can be reduced, and the reduction in the stirring torque is attained, as well.

Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To make the gap of an electrode pattern highly precise and enable good-yield manufacture by separating a column-shaped long electrode into electrodes of specific size by using an energy beam. SOLUTION: The column-shaped tentative long electrode 5 which has an upper column-shaped electrode 1a and a lower column-shaped electrode 1b electrically connected is inspected by a tester 7 as to an open circuit and a short circuit between the electrodes at a time (a). Then an energy beam irradiation device 8 form a gap 6 with an energy beam to make an electric separation. This method make inspection manhours less than those of individual inspection of the columnshaped electrodes 1a and 1b, and the inspection time is therefore shortened to improve the productivity. Similar effects can be obtained even when the electrode pattern is separated into not two, but >2 pieces. The precise gap 6 between the electrodes can be worked.

Title: Feedforward distortion compensating circuit
Inventor: SONE MASATO
IPC: H03F1/32
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To suppress carrier components which leak out into an extracted distortion signal over a wider frequency range than conventionally. SOLUTION: A signal branching off from a trunk line and a signal distributed by a distributor D1 via a delay circuit DL1 are coupled (1st loop) by a directional coupler DC2, and then the resulting signal and the signal distributed by the distributor D1 through the delay circuit DL1A are coupled (2nd loop) by a directional coupler DC2A. Thus, a distortion extraction loop is doubled to actualize satisfactory carrier suppression performance over a wide frequency range, without having to precisely set the delay times of the delay circuits DL1 and DL1A.
