Title: Driving device for objective lens
IPC: G11B7/085
Filed: 1992-04-02
Abstract: PURPOSE:To obtain the driving device for an objective lens having a high driving sensitivity by connecting a lens supporting member and an arm member by means of a pair of cylinders disposed to face each other via the air layer of a gap. CONSTITUTION:A driving part 13 for focusing is constituted of the objective lens 1, a cylindrical member 14 which is fitted with focusing coils 2a, 2b and the outer flank of which acts as a working surface and the lens supporting member 15 which connects the coils 2a, 2b and the cylindrical member 14. The driving force by the coils 2a, 2b is directly transmitted via the lens supporting member 15 to the objective lens 1 at the time of diving for focusing. On the other hand, the driving force by a tracking coil 3 is transmitted to the objective lens 1 by the air layer about 10mum gap which exists between the working surface being the outer flank of the cylindrical member 14 and the working surface being the inner flank of a cylindrical hole part 19 and functions as a means for transmitting the working force. Then, the driving force for tracking is transmitted via fluid. Since the ordinary operation of the optical head is executed at a high speed, the driving force is exactly transmitted to the objective lens 1.

Filed: 1980-06-16
Abstract: PURPOSE: To enhance the lubricating property and wear resistance of a porous metallic article by a method wherein a porous metal is delectrolytically treated in an aqueous solution containing a thiomolybdate or a thiotungstate as a main constituent, followed by a heating treatment if necessary.  
     CONSTITUTION: As a porous metal, for example, a metal subjected to porous chrominum plating or microracked chrominum plating, or a plastic material subjected to electroless plating followed by porous chromium plating or microcracked chromium plating is used. When the porous metal is electrolytically treated in an aqueous solution in which a thiomolybdate or a thiotungstate is dissolved, molybdenum sulfate or tungsten sulfate or the sulfide of the porous metal is produced and contained in the pores of the porous metal. After the electrolytic treatment is completed, the porous metal is washed with water and is dried, followed by heating treatment if necessary.

Title: Semiconductor integrated circuit
Inventor: NISHI HIROAKI
IPC: G01R31/28
Filed: 1987-04-03
Abstract: PURPOSE:To set a desired internal input value for an integrated circuit to be diagnosed and to observe an internal output value directly by providing a control circuit consisting of a T type FF and a selector in front of the input of a shift register and behind the output and controlling whether or not scan-in data and scan-out data are inverted.

Title: Fault location method
Inventor: TOOMASU OZUWARUDO
IPC: H04B10/00
Filed: 1991-03-22
Abstract: PURPOSE: To provide a simple method applicable even in the case that a fault is an intermittent electric fault in the case of locating the fault of the certain submarine long distance optical transmission system of plural optical relay system. CONSTITUTION: Connection is performed from a first terminating part TERM1 on the ground under a water surface to a second terminating part TERM2 on the ground through plural optical repeaters. Counters 1 and 2 at the respective terminating parts count frame alignment word(FAW) pulses and the counters 1 and 2 are started by the injection of a single error at the transmission rack 4 of the terminating part 2 by pulses from a pulse generator 5. When a signal error arrives at the other terminating part 1 after the delay of Nt clock pulses, the counter 1 is started. When a high voltage fault is present, the error is simultaneously generated on all fibers. Since propagation time from a fault part to the terminating part depends on the fault, the position of the fault is decided by a counted number on the stopped counter.

Title: Facsimile equipment
Inventor: SHIMOYAMA ATSUSHI
IPC: H04N1/00
Filed: 1992-04-03
Abstract: PURPOSE:To make a substitute call to simplify the operation of a telephone set by storing signal sequence while the called party is busy and originating a call to a circuit after reading it after the lapse of a prescribed time. CONSTITUTION:When a specific call signal '0' is called, a PB detection section 2 detects a signal '0' in the case of absence of the other party. A control section 4 controls a switching section 1 to change the call from a telephone set 7 to an exchange 8, setting the circuit route between them. Then, when a telephone number being the PB signal sequence is called from the telephone set 7 to the exchange 8, a storage 3 monitors the telephone number to store the telephone number. When the combined PB signals are called from the telephone set 7 after storing the telephone number for a fixed time in the storage 3, the detection section 2 switches a switching section 6 to make a call section 5 to call the telephone number being the PB signal sequence stored in the storage section 3 by means of the exchange 8. Thus, the telephone set 8 makes a call in place of the telephone set 7, simplifying the operation of the telephone set.

Filed: 1981-05-26
Abstract: PURPOSE:To suppress a local oscillation signal level, by synthesizing in opposite phase a local oscillation signal leaking out of a mixer, and an output which has branched from a local oscillator. CONSTITUTION:As for a signal generated from a local oscillator 6, one is inputted to an attenuuator (ATT) 5 by a coupler 7, and the other is inputted to a  delay line 8 by its some coupling quantity portion. The local oscillation signal  which has passed through the ATT 5 is mixed with a signal from an IF part 1  by a mixer 2, and the local oscillation signal itself leaks out of an output of the  mixer 2. On the other hand, the local oscillation signal which has passed through the delay line 8 is synthesized with the local oscillation signal which has leaked  out of the output of the mixer 2, by a circulator 9. In this case, when the delay  line 8 is adjusted so that a phase difference between the local oscillation signal  which has passed through the delay line 8, and the local oscillation signal which  has leaked out of the mixer 2 becomes 180 deg., it is possible to suppress a local  oscillation signal level inputted to a circulator 10.

Abstract: PURPOSE:To align the optical center position of a lens and the read center position of an image pickup element with each other by providing a means which moves the start positions of picture element read pulses in horizontal and vertical directions of an image pickup element driving circuit by extents corresponding to the arbitrary number of picture elements. CONSTITUTION:Picture elements of an image pickup element 1 in the CCIR system are read out by an image pickup element driving circuit 2 in the NTSC system. A microcomputer 3 reads in extents X and Y of movement of picture element read positions in the horizontal and vertical directions from terminals 4 and 5 respectively and generates driving data of the image pickup element based on these values to transfer it to the circuit 2. The circuit 2 generates a driving pulse by data from the computer 3 to control the picture element read start positions of the image pickup element 1. In this case of read in both systems, a picture element area corresponding to 16% of one horizontal scanning period is left unread in the horizontal direction. Consequently, the picture element read center position of the image pickup element 1 is shifted in horizontal and vertical directions within the range of 16% by extent, corresponding to the arbitrary number of picture elements, thus aligning the lens optical center position and the image pickup element read center position.

Abstract: PURPOSE:To process plural disks continuously by turning a rotary table which holds a disk mounting part which holds plural disks on the same plane in a loadable/unloadable way to shifting an optional disk to a reproducing means or a recording means. CONSTITUTION:When a disk 1 sets a magazine 27 turned to a disk store part 27a on a rotary table 29 of a shift stage 2, a loading motor 8 transmits its drive power to a rack 21 of a chassis 14 via gears 9 and 10.

Then a motor 30 revolves the table 29 via a belt 31 to set it at a prescribed position. Thus a motor 22 transmits its drive power to gears 23 and 24 via a belt 32. Then a rack plate 25 moves along guide grooves 25a and 25b and a drive plate 26 also moves. The pins 37 and 38 set on a substrate 40 are driven by the slant grooves 26a and 26b and move up along the vertical grooves 35a and 35b. The substrate 40 is kept horizontal and moves up. Thus a turntable 12 engages the disk 1.
