Patent JP-S61293758-A (JP)
Title: Transfer device
Inventor: ITO TERUYUKI
IPC: B23Q39/04
Filed: 1985-06-19
Abstract: PURPOSE:To enhance the locational accuracy and shorten the transport cycle by shifting the phase of the a crank arm in its operation start position by an angle of theta/2 with respect to a rotary cam in a transfer device which is to transport objects such as works to be machined. CONSTITUTION:A rotary cam 15 rotates in the direction of arrow to cause rightwise rotation of an L-shaped link 11 with 12 as fulcrum, and a coupling link 13 turns leftwise another L-shaped link 7 at a fulcrum 8 to allow a roller 9 at the tip to elevate a transfer bar 5 till the upper limit of the lift position L through a guide groove 10, and thus a pin 6 is set in a pin hole 4 in a work W. When a crank arm 16 to rotate together with rotary cam as in a single piece has turned leftwise 180 deg. over the dead point, a bar 23 advances said transfer bar 5 in the S direction through an advance/retraction link 17, to become opposite movement when 180 deg. is filled, that is the initial state. The phase of crank arm 16 in its operation start position is shifted by half the cam rotation angle theta necessary for elevation of the pin 6, and therefore the horizontal motion of pin becomes 1/2 to allow lessening of the pin hole, which should enhance the locational accuracy.

Title: Mechanism for detecting moving speed of magnetic head
Inventor: SAKURAI YOSHIKI
IPC: G11B5/596
Filed: 1982-07-30
Abstract: PURPOSE:To detect the moving speed of a magnetic head without damaging a packing space, by using a part of the winding of a voice coil, which is used when a magnetic disk device makes seek operation, for detecting the moving speed of the magnetic head. CONSTITUTION:When a fast seek instruction is delivered, a driving electric current is made to flow through a voice coil 801 in the direction shown by an arrow I and the coil 801 receives force of the direction shown by another arrow F and a supporting body 9 turns around a shaft 10. Therefore, another coil 802 also crosses a magnetic flux B. As a result, a voltage is produced across both ends of a resistance 16 and the moving speed of a magnetic head can be known by means of a voltmeter 15. When the fast seek is completed, the head 11 becomes possible to read the servo data of a disk 4. Therefore, at the time of seek other than the fast seek, the moving speed can be detected as in the case of conventional ones. Since the total number of turns of the coils 801 and 802 is equal to that of conventional devices when a switching circuit 14 is switched after the fast seek is completed, the seek operation is performed at a speed equal to a conventional speed at the time of the seek other than the fast seek.

Title: Numerical controller
Inventor: KOBARI KATSUO
IPC: G05B19/414
Filed: 1988-05-30
Abstract: PURPOSE:To enable the motor side to control the stop position of a motor by storing temporarily a control command to be transferred and stopping the motor at a prescribed position by the feedback signal concerning the speed and the position of the motor based on the data on the stop position and the revolving direction of the motor included in said control command. CONSTITUTION:The data on the absolute position and the revolving direction of a spindle motor 5 that decide the stop position of this motor are included in a command block which is read out in the prescribed timing at the side of a numerical controller NC1. Then said data are transferred to the side of a machine tool via a cable 3 together with the control data used for drive of a spindle. While the received data are temporarily stored at a setting part 6 at the side of a driver for the motor 5. When the conditions are satisfied for start of a motor positioning job in accordance with the contents of the data, the spindle is stopped with control at the absolute position shown by the data. The stop control of the spindle is carried out by operating a drive signal to stop the motor 5 at a prescribed position based on the feedback signal concerning the speed and the position of the motor 5. Thus the stop position of the motor can be controlled at the side of the motor 5.

Abstract: PURPOSE: To reduce the number of detectors for the remaining amount of ink and reporters by detecting the amount of ink in the tank, supplying ink from a spare tank, and indicating an ink stop in accordance with the detecting signal after the finish of supply operation.  
     CONSTITUTION: AND circuit AND1 is opened by the signal of typing finish, and the detecting signal of ink level of sensor 6b of ink tank 6 disposed at the carriage via OR circuit OR1 is applied to the circuit AND1 via detecting circuit 12. When  the ink level in the tank 6 is low, the carriage is moved via carringe drive circuit 14  to which the output of the circuit AND1 is applied, and the ink is replenished till  time-over signal is produced from timer circuit 15 to the tank 6 connected to the  spare tank with connector 6a, etc. This time-over signal is applied to the circuit  OR1 and AND circuit AND2. Therefore, when the level in the spare tank is similarly low, the device 13 indicates its warning with the detecting signal of the sensor  6b, and the remaining amount detector and indicator per tank are no longer  required.

The three gradation S1-S3 is compared and mode specified data, in which printing pulse signals are concentrated in the time series-like front section of the printing section of the line buffer 1b, are output to a pulse signal converter 4 at the time of S1<S2<S3 at that time. Mode specified data dispersed are, inversely, output at the time of S1>S2>S3. The gradation number for binary-coding of a gradation signal is output to the comparator 3 from the pulse signal converter 4.

Title: Dye-associated thin film, its production, optical switch and method for optical switching
Inventor: FURUKI MAKOTO
IPC: G02F1/35
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To obtain a dye-associated thin film to product an optical switch which can completely separate signal light from controlling light by forming a dye-associated thin film which consists of a J-association product of dye and which has a plurality of absorption wavelength peaks. SOLUTION: The dye-associated thin film consists of a J-association product of dye and has a plurality of absorption wavelength peaks. The J-association product consists of several tens to several hundreds of dye molecules which are regularly arranged and loosely coupled and which optically act as one super molecule. In the dye-associated thin film having the J-association product, not only the optical absorption efficiency increases but the threshold of the intensity of light necessary for absorption saturation decreases, and moreover, the recovery speed is quickened. As for the material of the dye-associated thin film, an association product of a squarylium dye is preferable from the viewpoints that the dye reproduces practically preferable absorption wavelengths and of chemical, thermal and optical stability. The number of absorption wavelength peaks is preferably three or more.

Title: Photomagnetic disk device
Inventor: SAITOU ATSUSHI
IPC: G11B11/105
Filed: 1984-06-29
Abstract: PURPOSE:To improve the thermo-magnetic stability of a magnetic domain to light power irradiated during reproduction, increase the quantity of reflected light from a recording medium, and obtain a reproducing signal with a high S/N ratio by canceling a diamagnetic field from the periphery of the magnetic domain formed during recording by a magnetic field in a weak erasure direction which is applied externally. CONSTITUTION:A photomagnetic disk 1 has a recording medium 2 and is turned by a rotating motor 3. Information is reproduced by utilizing such effect that incident light changes slightly its polarization direction corresponding to the magnetism direction of a recording film 2. When a recording magnetic field in the opposite direction of the magnetism direction of the recording film 2 is impressed simultaneously with the irradiation of light pulses, the impressed part is magnetized in the opposite direction as compared with the periphery and the formation of this magnetic domain 21 generates diamagnetic field at the periphery as shown by an arrow 22; and the magnetism of the magnetic domain 21 and the peripheral magnetism cancel each other when reproduced light power with which the recording film 2 is irradiated is increased. For the purpose, a weak erasing magnetic field is impressed to cancel the diamagnetic field. Consequently, thermomagnetic stability in a recording state is canceled. Consequently, the thermomagnetic stability in the recording state is secured even when a reproduced light power is increased.
