Filed: 1985-09-18
Abstract: PURPOSE:To hold the neutral position of an objective in a tracking direction precisely with a simple constitution and to reduce the size of an objective device by fitting plural magnetic material pieces at specific positions of the peripheral part of an objective holding cylinder. CONSTITUTION:Plural magnetic material pieces 11a-11d are fitted nearby the magnetic gap end part of the peripheral part of the objective holding cylinder 1 provided rotatably around a support shaft 7. Therefore, when the lens holding cylinder 1 rotates in a track direction, force for drawing a magnetic material piece which moves to outside the magnetic gap end part into the magnetic gap operates on the magnetic material piece with a magnetic field produced by leak magnetic flux, so that the magnetic material pieces and a magnetic circuit constitute a magnetic spring corresponding to a conventional rubber spring. Consequently, a tracking-directional position is held with high precision and the need for the rubber spring is eliminated to reduce the size.

Filed: 1982-11-24
Abstract: PURPOSE:To attain a high DC stability and an inexpensive circuit constitution by providing the 2nd operational amplifier whose positive and negative power supply terminals are connected in common to positive and negative power supply terminals of the 1st operational amplifier and which integrates an output of a boost circuit. CONSTITUTION:If a DC signal level of an output signal e0 is drifted positive due to any cause, since the 2nd operational amplifier 15 integrates the signal e0 by a CR time constant, an output voltage of the amplifier 15 is moved to negative polarity. As a result, since the current of a negative power supply terminal 15 is increased, a current of a resistor 28b and a collector current of a transistor 31b are increased by the increment, the collector voltage is moved to negative polarity and a DC signal level of the signal e0 is restored to zero. When the DC signal level of the signal e0 is drifted negatively, the current at a positive power supply terminal 15a of the amplifier 15 is increased and the DC signal level is restored to zero.

IPC: C08F8/00
Filed: 1993-08-20
Abstract: PURPOSE:To stably and economically obtain a polymer of good quality and good particle shape in high yield. CONSTITUTION:Propylene is continuously polymerized in the presence of a catalyst comprising (A) a solid catalyst component containing Mg, Ti, a halogen, and an electron-donating compound, (B) at least one member selected from organic compounds of Group IA, IIA, IIB, IIIB, and IVB metals of the Periodic Table, and (C) an electron-donating compound.

Title: Automatic focusing device
Inventor: AZUMI TAKASHI
IPC: G02B7/32
Filed: 1985-09-20
Abstract: PURPOSE:To simplify a mechanism by fixing a bisected photodetecting element (bisected PD) so as to make a light receiving lens rotatable, and rotating the light receiving lens so that a reflected light beam from an object can be moved on the bisected PD. CONSTITUTION:When the light receiving lens is rotated with respect to a light beam incident on the light receiving lens 6, a light receiving spot position changes in proportion to the the rotational angle of the light receiving lens. At this time, in terms of the light receiving lens, the light beam incident of the front main point 16 of said lens normally comes out in parallel at a back main point 17. When the photodetecting lens is rotated with the front main point as a center, the back main pint is moved by mu.beta due to an interval mubetween two main points and the rotating angle beta. Accordingly the light beam incident at the front main point does parallel displacement by mubeta and comes out at the back main point, whereby the image forming position of the emitting beam is moved by mubeta the same as the moving amount at the back main point. As a result, by rotating the light receiving spot formed on the bisected PD is adjusted to obtain the focused state.

Abstract: PURPOSE:To attain correct FM demodulation by inverting an output by either the leading edge or trailing edge of a rectangular FM signal and demodulating the output after a correct rectangular wave where the occupancy rate of a half of carrier frequency is nearly 50% is formed at an FF. CONSTITUTION:An analog input signal A is inputted to a demodulator 1 and becomes a rectangular wave signal B where the period is changed in response to an instantaneous amplitude of the input signal A. The signal B is inputted to an FF4 via a transmission system 2. The output of the FF4 is inverted by the leading edge (possible for trailing edge) of a signal C distorted through the transmission system 2 and an FM signal D having a correct rectangular wave where the occupancy rate of a half the carrier frequency is 50% is obtained from the FF4. An original signal is obtained by demodulating (3) the FM signal D. Thus, the pulse width distortion caused during the transmission is eliminated and correct demodulation is attained.

Abstract: PURPOSE:To prevent the deformation of rotor batten in machining the rotor core by shaping the dimension of the maximum outside diameter of at least one end ring of both end rings of a rotor core in the same dimension of the outside diameter of the rotor core. CONSTITUTION:By constituting a rotor core 18 in laminating rotor battens 17 and by pouring molten aluminum into this rotor core 18, end rings 19 and 20 and a slot bar 21 are to be integrally shaped at both ends and a slot 18a. At this moment both end rings 19 and 20 are shaped so that the dimension of their maximum outside diameter D may be the same as the outside diameter dimension d of the rotor core 18. Then in order to improve the precision of the outside diameter dimension of the rotor core 18, the periphery of this rotor 18 is cut machined by means of the lathe. In this case, when a bite 22 comes to the end of the rotor 18, a rotor batten 17 at its end surface is so pressed with the bite 22 that it is likely to be deformed. However, so long as the extreme outer perimeter is pressed with its end ring 20, the deformation can be prevented.
