Title: Brake device for unmanned moving vehicle
Inventor: NAKAO SHIYOUJI
IPC: G05D1/02
Filed: 1984-05-30
Abstract: PURPOSE:To cause a brake system to act as a safety device when an unmanned moving vehicle is braked, by providing brake wheels with a vertically moving mechanism which is moved down through the action of a limit switch, and by always placing the brake wheels in contact with the peripheral portions of driving wheels or driven wheels. CONSTITUTION:When a bumper 6 has collided againt an obstacle, a limit switch 7 inside the bumper is put in action so that a power supply 4 for a driver 3 is turned off and the electromagnet 12c of a controller 12 is excited. As a result, a lever 12b is turned clockwise by a core and disengaged from a latch 12a, and a rod 11c is moved down by a piston 10a so that brake wheels 8 are displaced into contact with the ground through the action of a shaft 8a. The brake wheels 8 are put on driven wheels 5 by links 9 so as to rotate in the opposite direction to the driven wheels. For that reason, the forces of the brake wheels 8 moving relative to the ground and those of the driven wheels 5 moving relative to the ground are equal to each other in magnitude and opposite to each other in direction. An unmanned moving vehicle can thus be stopped quickly.

Title: Motion disturbance detector
Inventor: NAGAO YOSHIHIRO
IPC: G11B19/28
Filed: 1995-04-13
Abstract: PURPOSE: To detect the motion disturbance of a mobile object by outputting an error pulse based on phase difference between a pulse signal corresponding to the moving speed of the mobile object to be inputted to a phase lock loop(PLL) and a pulse signal from the voltage controlled oscillator(VCO) of the PLL. CONSTITUTION: An encoder 11a of a motor generates the sequence of pulses corresponding to the moving speed of the mobile object. A phase comparator 17 consisting of the PLL of a motion disturbance detector 16 inputs a signal S1 from the encoder 11a and a pulse signal S2 through a frequency divider 20 of a VCO 19, compares the phases of two pulse signals and outputs an error pulse S3. An LPF 18 inputs the pulse S3, generates a control voltage S4 corresponding to its frequency and outputs it to the VCO 19 and a time/voltage converter 21. Based on the voltage S4, the coverter 21 converts the pulse S3 to a saw-tooth wave S5. A voltage comparator 23 inputs the sawtooth wave S5 through an LPF 22, compares the peak value of S5 with a reference voltage S6 and detects the motion disturbance.

Abstract: PURPOSE:To keep the occurrence of the abrasion of a rotor and the shaving or the scratch of the surface of a body to be contacted by the rotor as little as possible and to stabilize and maintain durability in the performance of a device by disposing and providing the rotor so that it may rotate in contact with the body to be contacted in a direction where surface frictional force along the periphery of the rotor becomes small. CONSTITUTION:A transfer roller 2 is disposed to a photosensitive drum 1 being the body to be contacted in the direction where the surface frictional force along the periphery of the roller 2 becomes small, that means, it is disposed so that it may rotate in contact with the drum 1 to follow bristles. When the surface of the roller 2 in the vicinity of a transfer part 10 in the case of disposing the roller by following the bristles is examined, the frictional force of the roller 2 becomes small to a transfer material carrying direction, so that rubbing between the roller 2 and the drum 1 becomes small, the roller 2 is hardly abraded, the change of diameter of the roller 2 caused by the abrasion is decelerated and carrying force is not lowered for a long time. Thus, the occurrence of the abrasion of the rotor and the shaving or the scratch of the body to be contacted by the rotor and various kinds of adverse effects caused by the abrasion, the shaving and the scratch, etc., are kept as little as possible and the durability in the performance of the device is stabilized and maintained.
