Title: Brake unit
Inventor: KATAUE NOZOMI
IPC: F16D65/22
Filed: 1982-01-18
Abstract: PURPOSE:To obtain safe and trustworthy release of a braking force by connecting the center part of a movable plate to an end part cover through an elastic body which acts in such a manner that the movable plate is attracted toward an end part cover side. CONSTITUTION:When a brake pedal is stepped on, an operation rod 20 turns a revolving shaft 18, and forces a movable plate 8 to turn around its shaft via a revolving piece 19 and a pin 36. And owing to the operation of a steel ball and a recessed part 12, the movable plate 8 undergoes the force which pulls the plate 8 away from an end part cover 7, and moves to a friction part side 4. When the brake pedal is put back, the movable plate 8 turns back to the original position. However, a coil spring 24 is energized in such a way that the movable plate 8 is pressed against the end part cover side 7 at this time. Therefore, the movable plate 8 is detached quickly from the friction part 4 so that the braking force is released.

Title: Beam light scanning device and image forming device
Inventor: TANIMOTO KOJI
IPC: H04N1/04
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To exactly control the exposure position in scanning direction at all the time even with an optical system, of which the order of beam light is not clear, by performing control so that the scanning range on a surface to be scanned is to be a prescribed range. SOLUTION: A main control part 51 respectively individually sends forced emission signal to laser drivers 32a-32d and forcedly maker a laser oscillator emit light. While an on-drum emission inhibit signal is outputted from an on- drum emission inhibit timer 122, concerning the laser drivers 32a-32d, the forced emission signal from the main control part 51 is made invalid. When the beam light is scanned by a polygon mirror, the surface of a sensor pattern S1 of a beam light detecting device 38 is scanned so that a pulse signal outputted from the sensor pattern S1 is defined as a reference for the operation timing of the on-drum emission inhibit timer 122. Thus, the main control part 51 can expose the surface of the beam light detecting device 38 with any arbitrary beam light without caring of the motion of the beam light.
