Title: Walking type dolly with assist power
Inventor: YUKI HITOSHI
IPC: B60L11/18
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To restrain consumption of a battery and lighten labor by beginning operation of an electric motor, when the larger detected value of the detected values of a pair of pushing force detecting sensors respectively detecting the pushing force of both hand pushing handles is over a set value. SOLUTION: When pushing force is applied to a grip 56, the grip 56 is advancingly moved against a handle shaft 55 up to the position where the spring force of a coil spring 69 is balanced with the pushing force. For detecting the pushing force to the grip 56, the flange 74 of a pushing force detecting sensor 73 is fastened to a bracket 72 fixedly mounted on the rear end part of a hand pushing handle 20. When the larger detected value of the detected values of the right and left pushing force detecting sensors 73, 73 is over a set value, an electric motor is controlled to operate so as to exhibit assist force corresponding to the larger detected value. Hereby, labor is lightened so as to enable a dolly to run on the uneven ground in the full load condition, and at light load, the electric motor is not operated so as to restrain consumption of a battery to be small.

Abstract: PURPOSE:To obtain wafers with small dispersion in thickness and as well as with excellent parallelism by a structure wherein a holding body is coupled through a spherical beaing structure with a fulcrum shaft in order to apply a constant load to the wafers at all times so as to uniformly lap the wafers. CONSTITUTION:The semiconductor wafers 3 are held on the circular disc shape holding body 4 supported by the fulcrum shaft 5.

Abstract: PURPOSE:To obtain satisfactory quality and to easily and securely control mute operation by detecting that an object exists near a transmitting microphone with a detecting means, reducing the gain of an amplifying means with a detecting output and preventing the generation of howling. CONSTITUTION:When a photo-detecting part 10a of a photo-transistor(PTr) 10 is shaded by the object to exist near a calling microphone 1, the PTr30 is turned off. At such a time, since a PTr11 is turned on, an turning-on signal is outputted from a comparator 14. A transmitting gain control circuit 18 receives the turning-on signal and a switching Tr1 is turned on. Then, a control signal is inputted to a transmitting ATT16. As a result, the attenuation factor of the ATT16 goes to be large and the level of a sound signal, which is sent to a transmitting circuit, is reduced. On the other hand, the output of the comparator 14 is inputted to a timer circuit 17 as well and the circuit 17 measured a time until a turning-off signal is outputted from the comparator 14. Then, a prescribed time passes, the turning-on signal is outputted and the control signal is sent to the transmitting ATT16, then, a mute condition is obtained.

Title: Magnetic head supporting device
Inventor: ISOZAKI MAKOTO
IPC: G03B27/72
Filed: 1993-04-06
Abstract: PURPOSE:To attain a good contact between a head and a film by placing the abutting section of the supporter to the film behind the magnetic head rather than at the gap of the head. CONSTITUTION:Rollers 601 and 602 are placed against a magnetic head 101 and rotate in accordance with the traveling of a film F. However the contacting position to the film F is placed behind the head 101 rather than at the gap located at the tip of the head 101. Having this configuration, the film F, which is held between the two rollers 601 and 602 and the head 101, is slightly deformed, moves along the surface of the head 101 and keeps a contact by the elasticity of the film F while it moves. Therefore, a proper head touching pressure is obtained. Since the film F moves along the curved surface of the head, no separation between the gap and the magnetic surface occurs even when the gap position shifts forward or backwards.
