Title: Cable bender
Inventor: YOSHINARI SHIGERU
IPC: B21D7/024
Filed: 1995-06-21
Abstract: PURPOSE: To bend a thick and very rigid cable easily by displaying an inside abutting section from an inside outer surface of the cable toward an outside outer surface, while decreasing the distance between a connection shaft formed at the center of a first link means and a connection shaft formed at the center of a second link means. CONSTITUTION: A connection shaft 6 is formed at the center of a first link means 4 and a connection shaft 6' is formed at the center of a second link means 4'. When the distance between the connection shafts 6 and 7' is shortened by means of a drive means 7, an inside abutting section 3 is displace from an inside outer face of a cable 2 toward an outside outer face and at the same time, a first outside abutting section 5 and a second outside abutting section 5' are relatively displaced in the direction opposite to the displacement direction of the inside abutting section 3. Therefore, the cable 2 can be bent around the inside abutting section 3 by means of the first outside abutting section 5 and the second outside abutting section 5' so that the inside abutting section 3 may be located inside. By this method, even a thick and very rigid cable 2 can be bent easily.

Title: Load controller
Inventor: YAMANO SHINICHI
IPC: H02P7/29
Filed: 1990-07-04
Abstract: PURPOSE:To continuously change the duty of an output duty control signal by producing and outputting a duty control signal based on the measuring results of the 1st and 2nd measuring means and the contents of a holding means. CONSTITUTION:A 1st measuring means 31 measures a period when the duty signal inputted via a communication line is kept at a high level for example. A 2nd measuring means 32 measures a period when the duty signal is kept at a low level respectively. The peak value of the measuring result of the means 31 is held by a peak holder 33. When the measuring result of the means 31 is smaller than the contents of the holder 33, i.e., when the duty of an input duty signal is reduced, the measuring result is reduced with a prescribed changing rate, for example, and updated. A signal generating means 36 discriminates the level of a transmitted signal which varies periodically and produces an output duty control signal having a frequency sufficiently higher than the input duty signal. Thus the duty of the output duty control signal is continuously changed in response to the input duty signal.

IPC: F16C32/04
Filed: 1989-07-10
Abstract: PURPOSE:To prevent vibration while a rotor is rotated excessively by providing on the internal circumference of a stator electromagnetic poles with exciting coils and displacement detectors opposed with each other through a clearance between the rotor and a stator, and controlling the phase of an output from the detectors to control the suction force of the electromagnetic poles. CONSTITUTION:Two displacement detectors 61 and 62 for detecting vertical and lateral displacements of a rotor 1 are fixed near the poles of electromagnetic poles 41 to 48 with their detecting directions crossed at right angle. When the rotor 1 is rotated at high speed and the whirling is produced, the vibration displacement of the rotor 1 is detected by these displacement detectors 61 and 62. A phase-modified signal is produced in a phase controller 72 by means of the displacement signals, transmitted to a distributor 73, and a current corresponding to the phase-modified signal is applied to exciting coils 51 to 58 through current amplifiers 74 and 75. A magnetic suction force acts between the electromagnetic poles 41 to 48 and the rotor 1, a magnetic suction force, 90 deg. ahead of the displacement of the rotor in phase, acts as a damping force to suppress the vibration displacement magnitude of the rotor 1, and the rotor can be rotated excessively without producing vibration.
