Title: Manufacture of preform for optical fiber
Inventor: KAMIYA TAMOTSU
IPC: G02B6/00
Filed: 1983-12-02
Abstract: PURPOSE:To prevent the expanding and bursting of a reaction tube at the position by keeping the internal pressure of the reaction tube in the vicinity of the position on the supply sie of a glass material where the forward trip of a burner is started higher than the external air pressure and lower than the internal pressure of the other part in an internal CVD method. CONSTITUTION:A reaction tube 2 is rotated, and a glass material is supplied from one end. A burner 5 is travelled rightward, and high-pressure air is supplied into a control chamber 3 by a fan 13 to keep the internal pressure of the chamber 3 at P1 which is necessary for keeping the equilibrium with the shrinking force of the reaction tube 2. when the burner 5 reaches the terminal of the forward trip and strikes against a limit switch 6b, the opening degree of a motor valve 14 is decreased and the flow rate of the high-pressure air is reduced to keep the internal pressure of the control chamber 3 at P2 which is lower than the pressure P1 and slightly higher than the external air pressure. The pressure P2 is kept until the burner 5 collides against a limit switch 6a on the other side and changes its direction and a specified time elapses. The pressure P1 is increased to P2 after a specified time.

Title: Control method for carrier for plural reversing hot hoop rough rolling machine
Inventor: ORINO MICHINORI
IPC: B21B1/02
Filed: 1985-10-14
Abstract: PURPOSE:To perform effective rough rolling and to improve productivity by predicting a predecessor slab tail end position at the beginning of rolling on the successor slab based on a carrying locus of the successor slab top end and controlling so that an idle time of a succeeding mill is min. CONSTITUTION:A top end locus of a slab B rolled to be RI is bited by an R1 at the time of t0 by VM1, reaches P1 at the time of t1 by V1, and goes on a T1 table. It is necessary that the tail end of the slab B passes over the T1 table at that time. If the initial position of the tail end of the slab B at the time of tMPC is a distance from R1 to LT1 by an inverse operation using V2 and VM2, the tail end locus of the slab B can pass through P1' at the time of t1. The top end locus of a slab A reaches P2 at the time of t2 and goes on a T1 table by progress of rolling at the R1. The initial position LT2 by which the tail end locus of the slab B passes through P2' at the t2 is obtained in the same manner so that the tail end locus of the slab B can pass over the T2 table at the t2 and LT3 is also obtained. By repeating that calculation, the max. value of LTmax is the least sufficient condition of a tail end position of the slab B at the beginning of rolling on the slab A.

Title: Magnetooptical recording disk and magnetooptical disk device
Inventor: KUREBAYASHI MASAAKI
IPC: G11B11/10
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of cross write and to densify a track by deviating the ruggedness of a mark between adjacent tracks. SOLUTION: The phases of the respective marks of signals recorded in a track Tr-A and a track Tr-C are the same but that of a signal recorded in a track Tr-B is shifted by a half clock to each other. As to the phase of a laser pulse, the tracks Tr-A, C are irradiated with the same timing and Tr-B is irradiated being lagged by a half period. By the irradiation like these, since the position of the mark is formed while being shifted between adjacent tracks and the mark becomes a rugged waveform at its edge in the magnetic field modulation recording by projecting a laser pulse, the influence of cross write is removed.

Title: Automatic output level control circuit
Inventor: MOCHIZUKI TAKUSHI
IPC: H03G3/30
Filed: 1993-08-20
Abstract: PURPOSE:To form an automatic output level control circuit preventing the generation of spurious components by stopping a clock after a level is converged, in an automatic output level control circuit always controlling the output level of an amplifier to the constant by controlling the attenuation amount of an attenuator provided on the input side of the amplifier. CONSTITUTION:The attenuation of an attenuator 11 is controlled by the control current from a D/A converter 16 so that the detection voltage from a diode 13b may be almost equal to the reference voltage of a comparator 14. When the detection voltage is within the voltage range corresponding to a RF output level allowable range, the output signals of comparators 25 and 26 become an 'L' level and an AND circuit 27 becomes a gate 'close' state. Thus, because the clock from a terminal 28 is interrupted by the AND circuit 27, a U/D counter 16 stops a counting operation and holds the output count value to the value just before the output.
