Title: Electric open-close device
Inventor: HARA TAKASHI
IPC: H04Q9/00
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To conduct the open-close operation of a body to be opened and closed surely even when a shield is interposed by connecting a signal converter for converting a radio signal from a remote control device into a power-line carrier signal to a power line in common with a control section. SOLUTION: A signal converter 43 is installed beforehand to a plug socket 42, in the periphery of which there is no shield such as a curtain 31. When an infrared signal indicating open-close operation such as the opening, closing and stoppage of a shutter 11 is transmitted from an infrared remote controller 21 at that time, a signal A from the remote controller 21 is received to an infrared reception means for the signal converter 43, and a power-line carrier signal is overlapped and sent to a power line 41 through a coupled circuit from a power-line carrier-signal transmission circuit. Since the converter 43 is connected to the power line 41 at that time, the signal A from the remote controller 21 surely reaches the converter 43 so far as there is no shield in the periphery of the converter 43. Consequently, communication having high reliability is conducted between the remote controller 21 and the converter 43. Accordingly, the certain open-close operation of the shutter 11 can be realized.

Filed: 1990-03-03
Abstract: PURPOSE:To improve operability by pivotally providing a cam pedal, extended in the peripheral surface direction of a rotary body, on a fitting board to which the rotary body is fitted, and an engaging piece is engaged with a wheel supporting yoke by the pivoting of the pedal to lock the rotary body, in a caster in which a travel direction can be fixed.

Title: Tracking controller
Inventor: HIRASAWA KAZUO
IPC: G11B15/467
Filed: 1989-03-03
Abstract: PURPOSE:To maintain satisfactory tracking even when a reproducing pilot signal from an adjacent track is omitted by monitoring a reproducing signal, and substituting a signal of constant specification for a tracking control signal when the signal level of the reproducing signal goes less than a constant level. CONSTITUTION:A second envelope detection circuit 13 detects the envelope level of the whole of the signal reproduced from a home track, and inputs its output to a level deciding circuit 14. The level deciding circuit 14 decides whether or not the level of the reproducing signal is less than a threshold value decided in advance, and outputs a decided signal to a delay circuit 15. When the envelope level exceeds the threshold value, the output of a differential amplifier 7 is inputted to a motor driving amplifier 8, and when it is less than the threshold value, the output voltage of a constant voltage circuit 16 is inputted to the motor driving amplifier 8. Thereby, it is possible to maintain the feed speed of a magnetic tape at reference speed even when the reproducing pilot signal from the adjacent track is omitted, and to prevent the remarkable deviation of the tracking occurring.

Title: Position detector
Inventor: NODA TOMOYA
IPC: G01B11/00
Filed: 1994-02-28
Abstract: PURPOSE:To indicate the position of rugged mark in sharp contrast by detecting the change in interference state of the rugged mark at an edge position that is formed on a micro object based on the detection result by means of a photoelectric detection means. CONSTITUTION:When a light flux 11 generating from a light source 1 is to be led to an object 3, an illumination light flux is converted to linear-polarized beams having planes of polarization perpendicular to each other and they are directed onto various positions on the object 3 with a minute interval. The polarized beams are reflected on the surface of the object and they are deformed in waveform due to steps between its projecting part and flat part, so that a phase difference is generated based on the difference between respective light path lengths up to a detection system. After two reflected beams of light are combined on a same light path, they are subject to mutual deflection interference. At this time, since the light path length does not differ from each other in a part corresponding to the projecting and flat parts, an interference image with light path difference of zero can be obtained. Thus, the change of a rugged mark at an edge on the object 3 is detected based on the detected result by a detector 2, thereby detecting the mark position.

Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To quickly fasten a screw with a small screw driving and pushing force by rotating a spindle at a speed in a specified range, while driving the screw with a pitch in a specified range. SOLUTION: A spindle 20 is formed so as to be rotated with a driving gear 11 when a clutch tooth 32 of the spindle 20 is engaged with a clutch pin 31 and a clutch tooth 30. The driving gear 11 is rotated at a high speed such as 5000 rpm-7000 rpm, and a screw is driven with a pitch at 1.3 mm-2.0 mm. When the spindle 20 of a screwdriver is rotated at 6000 rpm of speed, the screw fastening speed becomes about 130 mm/s-200 mm/s, which coincides with the bending and stretching movement of arm capable of restricting the fatigue of worker at the minimum. Driving work capable of restricting the fatigue at the minimum can be realized by limiting the number of revolution of the spindle 20 in a range at 5000 rpm-7000 rpm.
