Title: Optical pickup
Inventor: EMOTO MASAMI
IPC: G02B7/28
Filed: 1982-01-27
Abstract: PURPOSE:To extend the limit of detection of focus, by arranging a substance having a >=1 refractive index such as glass in a space of an optical path and shifting the image forming position of a modulated light with an objective lens while keeping a constant optical length, relating to a focus detector reading information on a disc optically. CONSTITUTION:In the optical path of the astigmatic difference method, a transparent parallel plate 10 is arranged. The operation of the parallel plate in the condensed luminous flux is to shift the light condensing point by (b). In using the objective lens having 4mm. of focus, when a cylindrical lens is placed at a position placed at 307mm. from the objective lens, although the detectable range is 300mum with the absence of the plate 10, the range is spread to 400mum by inserting the plate 10. The insertion position of the plate 10 can be placed in any position of the space in the optical path and it is most effective to be placed between a 1/4 wavelength plate and the objective lens, concretely in the actuator.

Abstract: PROBLEM TO BE SOLVED: To detect a collision at high sensitivity without limiting the collision direction by detecting the displacement of a contact sensing member arranged on an attachment to be connected to a main shaft sleeve or a main shaft end, and transmitting a contact signal to a controller by a radio signal. SOLUTION: When the position of a stylus is displaced after the stylus of a main shaft unit is brought in contact with a work piece by reckless driving of a machine tool, an oscillating member 105 connected to a connecting part of the stylus is oscillated or moved in the lateral and axial longitudinal directions. A projecting part 105b of the oscillation member 105 is oscillated or moved similarly to the oscillating member 105, and a free moving member 93 to be brought in contact with the projecting part 105 is upward moved. The upper end of the free moving member 93 is brought in contact with a limit switch 97, and a contact signal is output from the limit switch 97 to a transmitter. The signal is modulated into a radio signal, and the radio signal received by a receiving antenna through a transmitting antenna is output to a controller.  The radio signal is demodulated into the contact signal, and an emergency stop command is output to an NC device.

Title: Time base collector
Inventor: NAKAMURA TAKAO
IPC: G11B20/02
Filed: 1986-01-22
Abstract: PURPOSE:To eliminate the disturbance of a video signal at a search mode and to simplify the circuit constitution by detecting the deviation of an address at the search mode to hypass an input signal to the output side. CONSTITUTION:Since the horizontal synchronizing number during one vertical synchronizing period differs from that at the normal operation in an input signal (a) at a search mode, there exists a deviation between a write address of an address timing circuit 9 and the vertical synchronization of the input video signal. Then a write address deviation detection circuit 10 is operated, a bypass circuit 11 is activated and the input signal (1) is bypasses at the output. Although the write address is deviated and the video signal at the output of a D/A conversion circuit is fluctuated to a vartical synchronizing signal or causes disturbance in the search mode in such a way, since the bypass circuit is operated at the video signal output, the input signal is outputted as it is and no vertical fluctuation nor disturbance is caused in the video image. Further, a complicated circuit to prevent the write address deviation is not required and the circuit scale is decreased.

Abstract: PURPOSE:To reduce an air gap without narrowing an interval between a stator yoke and a rotor by superposing and winding a strip-shaped copper wire and a strip-shaped iron wire, shaping them so that the side end collecting surfaces become arcuate, and securing them to the inner periphery of a stator yoke.
