Abstract: PROBLEM TO BE SOLVED: To produce an optical reflection mirror capable of precisely reflecting laser beams in prescribed directions and capable of preventing the occurrence of cracks in the constituent members of the mirror and to provide an image forming device equipped with the mirror. SOLUTION: A plastic molding 80 with a reinforcing member 83 bonded through an adhesive layer 82 is molded by the injection-compression molding method using a metallic mold.

Title: Cycle measuring device
Inventor: WATANABE HIDEO
IPC: G01P3/488
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a cycle measuring device, which can maintain the precise detecting accuracy adapting to a change of the detecting characteristic of a sensor. SOLUTION: Voltage pulse at a cycle, which is inversely proportional to the rotating speed of a gear 11, is supplied to a comparator 15 by a sensor 12 provided near the gear 11. This voltage pulse is compared with the reference value, which is output from a microcomputer (μP) by the comparator 15, and the output of the comparator 15 is applied to an auto save resister(ASR) of the microcomputer μP 16. The ASR detects a rise of the voltage pulse, and reads out the real time from a free-run timer, and computes the cycle on the basis of a difference between the real time and the time, which is read at the last time. This cycle can be accurately detected by determining a reference value on the basis of the computed cycle.

Title: Controlling circuit for inverter
Inventor: OKATSUCHI CHIHIRO
IPC: H02M5/458
Filed: 1990-10-08
Abstract: PURPOSE:To reduce the noise of a motor without raising the switching frequency of an inverter by reducing the distortion of an electric current by controlling an input current to a sine wave-like shape and partially controlling a DC voltage in accordance with the setting of frequency to the inverter. CONSTITUTION:A DC voltage is raised to its rated value and the percentage modulation of PWM and the voltage of an inverter are respectively raised to the highest values at the point where the frequency of the inverter is (b). During the period when the frequency of the inverter changes from (a) to (b), the voltage of the inverter is linearly changed by controlling a DC voltage proportionally to the frequency of the inverter while the percentage modulation of PWM is maintained at the highest value. When the frequency of the inverter is lower than (a), the voltage of the inverter is dropped by lowering the percentage modulation of PWM while the DC voltage is maintained at a fixed level. In addition, the lowest value of the DC voltage is set to a value a little higher than the peak value of an input AC voltage. Therefore, the efficiency can be improved and, at the same time, the noise of a motor caused by a ripple current can be reduced, because the PWM is performed by dropping the DC voltage and the ripple current is reduced by about 1/2 within the lowfrequency range of the inverter.
