Title: Controller for synchronous motor
Inventor: TAKAHASHI SHIYUUICHI
IPC: H02P8/42
Filed: 1978-09-14
Abstract: PURPOSE:To prevent wrong operation at the time of power cut-off which is a drawback inherent in open-loop control, by controlling a polyphase synchronous motor in a closed loop. CONSTITUTION:The position of an apparatus, which is controlled by a gear unit which consists of gears 81, 82 and is driven by the polyphase synchronous motor 10, is detected by a shaft encoder 83. The difference between the detected position and a reference position applied to an input terminal 84 is calculated by a subtraction circuit 85. The absolute value of the difference is picked out from a terminal 850. The polarity of the difference is picked out from another terminal 851. A signal processor 86 is a limiting circuit for preventing the absolute value of the differecnce from exceeeding a setpoint. An accumulator consists of an addition circuit 87, a latch 88 and a clock pulse circuit 89. When  the sum calculated by the addition circyit 87 exceeds the capacity of the accumulator, an overflow pulse corresponding to the change in the position angle of the motor 10 is generated. A control signal for the increase and decrease in the position angle of the motor 10 is produced by a counter depending on the output of the addition circuit 87 and the polarity of the difference.

Title: Gas meter
Inventor: KURAGANO TAKETOSHI
IPC: G01F3/22
Filed: 1985-05-24
Abstract: PURPOSE:To make a gas meter small in size by stopping the operation of a valve which reciprocates on the valve sheet of a distributor instantaneously between both poles of its stroke. CONSTITUTION:A valve arm 24 is put in continuous motion around a pivot 6 through the rotation of a crank shaft 15. A repulsive force is charged by the compressive deformation of a leaf spring 26 and the valve 5 is held at its original position until the arm 24 reaches a dead-point position where fulcra of coupling at both ends of the spring 26 and the center of the pivot 6 make a straight line. When the leaf spring coupling point atop of the arm 24 exceeds the dead-point position, the force charged by the compression of the spring 26 is released at a time. Namely, the valve 5 swings instantaneously in the opposite direction from the motion direction of the arm 24 and stops at the other shock pole position by abutting on a stopper 27. The arm 24 rotates counterclockwise awhile and is then inverted to rotate clockwise, and the valve 5 is held in a stationary state at the front position as it is until the arm reaches the dead-point position of swinging.

Filed: 1989-05-02
Abstract: PURPOSE:To reduce the capacity of a timing table by sharing a timing table with when an image is formed on a first surface and when an image is formed on a second surface. CONSTITUTION:A CPU 150 inputs a print count signal PRINTCNTn from a counter 110 counting outputs from a timing pulse oscillator 100 and a timing table from a RAM 130 storing a control instruction pairing with the signal. The CPU 150 controls the operation of each part in line with operation contents of operating parts represented by the counted value on the timing table to which the value counted by the counter belongs. This timing table is shared with when an image is formed on the first surface and when an image is formed on the second surface. A prescribed correction value is substituted for the signal PRNTCNTn when the leading edge of paper passes through a supply sensor at the time of printing it on the second surface; therefore the timing table can be shared with when an image is printed on the first surface. Consequently, contents in the timing table can be reduced.

Abstract: PURPOSE:To prevent an effect from the outside on an IC built-in capacitor by forming a second wiring layer connected at an output terminal having small impedance onto a first wiring layer connected at an input terminal having large impedance through an intermediate insulating film layer. CONSTITUTION:An insulating film layer 42 consisting of a thermal oxide film is formed onto an silicon semiconductor substrate 4, and a first wiring layer 43 is shaped onto the layer 42. An intermediate insulating layer 44 is formed onto the first wiring layer 43 and the insulating film layer 42, and a second wiring layer 45 is shaped onto the layer 44. An IC built-in capacitor is constituted by these first wiring layer 43, intermediate insulating film layer 44 and second wiring layer 45, and the second wiring layer 45 is used as an A side electrode and the first wiring layer 43 as a B side electrode. The B side electrode easy to pick up noises is employed as a lower side electrode and the A side electrode, which has small impedance and does not pick up noises, as an upper side electrode. Accordingly, since the lower side electrode easy to pick up noises is shielded by the upper side electrode, the IC capacitor is difficult to be affected by noise from the outside.
