Title: Optical amplifier
Inventor: NAGANO KATSUMI
IPC: H04B10/00
Filed: 1986-03-06
Abstract: PURPOSE:To realize an optical amplifier generating a light output proportional to the difference between two light inputs with very simple circuit constitution by allowing a drive means to drive an electrooptic conversion element by a current proportional to the difference between both photovolatile currents of the 1st and 2nd photoelectric conversion elements. CONSTITUTION:An amplifier A amplifies the difference between the photovolatile currents IP1, IP2 of photodiodes PD1, PD2 to supply a forward current IF to a laser diode (electrooptic conversion element) LD. Thus, the laser diode LD generates a light output P0. Let the current amplification factor of the amplifier A be beta, then the forward current IF of the laser diode LD is expressed as IF=beta(IP1-IP2). When the current amplification factor beta is sufficiently large, the light output P0 is expressed as P0=1/k(P11-P12) and the reciprocal of the feedback quantity of the light output P0 is the amplification factor of the circuit. The light output P0 is proportional to the difference of inputs (P11-P12).

Title: Timing circuit
Inventor: SANADA TAKESHI
IPC: H04L7/027
Filed: 1988-03-02
Abstract: PURPOSE:To prevent identification error from easily being caused by compensating so that a phase fluctuation characteristic of an output signal with respect to an input level of a limiter amplifier is made flat. CONSTITUTION:The circuit is provided with a peak detector 6 detecting the amplitude of an input signal of a limiter amplifier 5 and a variable phase shifter 7 varying the phase of a limiter amplifier output signal in response to the output of the detector 6. Then the peak of an output signal of a timing extraction filter 4 inputted to the limiter amplifier 5 is detected to control the phase of the clock signal of the limiter amplifier output by the variable phase shifter 7 in response to the output of the detector 6. Thus, the identification timing in an identification reproducing device 2 is kept optimizingly to identify and recover the reception signal. Thus, the identification error is hardly caused.

Title: Method and device for processing typeface information
Inventor: MATSUO HIROKO
IPC: G06T11/20
Filed: 1994-03-18
Abstract: PURPOSE:To exclude a void at the time of painting-out by reconstituting closed curves consisting of a character shape inside a vector font so that the closed curves can not be mutually crossed. CONSTITUTION:The character shape is prepared by the new closed curves for which the crossing of plural closed curves consisting of the character shape inside the vector font is canceled. As shown in the figure (a), for example, since the character shape of 'naka' (written in Chinese character) composed of three closed curves G1 to G3 is provided with the mutual crossing of closed curves at sections 3a and 3b, the voids are generated when painting out the area surrounded by the closed curves. Therefore, the segments consisting of the respective closed curves G1 to G3 are divided into contour pieces after considering the intersections as shown in the figure (b), and the contour pieces are coupled based on prescribed rules. Thus, the character shape of 'naka' can be formed by new closed curves G4 to G6, which do not mutually cross, as shown in the figure (c).

Abstract: PURPOSE:To obtain the titled self-adhesive capable of sticking to and imparting durability suitable for processing to an adherend, by incorporating a polyfunctional thiol and an acrylic monomer in a mixture of a radiation-curable prepolymer with a radiation curable oligomer. CONSTITUTION:A self-adhesive prepared by incorporating a mixture comprising 75-95 pts.wt. radiation-curable prepolymer (A) having a (meth)acryloyl group of 5,000-50,000 in molecular weight in its molecule and 5-25pts.wt. radiation-curable oligomer (B) having a (meth)acryloyl group of 500-3,000 in molecular weight in its both terminals with 0.2-20pts.wt. polyfunctional thiol (C) and 50-100pts.wt. acrylic monomer (D) having an alkali-reactive group. When the molecular weight of the component (A) is less than 5,000, the product does not have rubber properties which are necessary as a self-adhesive while when the molecular weight is more than 50,000 the product has a high viscosity in the absence of a solvent, leading to difficulty in coating it. When the molecular weight of the component (B) is less than 500, the properties thereof cannot sufficiently be displayed, while a molecular weight of more than 3,000 causes an insufficient radiation curing in the presence of a large amount of an alkali-reactive monomer.

Title: Stopping method for operation of rolling mill in case of occurrence of sheet fracture
Inventor: FURUKAWA KUSUO
IPC: B21B33/02
Filed: 1980-04-14
Abstract: PURPOSE: To surely prevent the rolling rolls from being damaged by the cobbling phenomenon when a sheet fracture occurs, by controlling the rate of slowdown of the sheet threading velocity in two adjoining rolling stands on just upstream side and on just downstream side of the point wherein the sheet fracture occurred, so as to be smaller than the rate of slowdown in the rolling stands on further upstream side than the said just upstream rolling stand.  
     CONSTITUTION: When the rolling speed of each stand and the interstand tension, etc., become larger than prescribed values, a signal of "under operation" is sent from the rolling work detector 32 to the fracture position detector 34. If a sheet fracture occurs, the fracture position detector 34 produces an output obtained from signals of AND circuit, NAND circuit and the rolling work detector 32, and this output is inputted to the secondary fracture generator 36. If the sheet fracture occurs between the fifth rolling stand 20-5 and the sixth rolling stand 20-6, for example, the secondary fracture generator 36 quickly steps the fourth rolling stand 20-4 and its upstream stands by the time t 1  seconds, and ordinarily stops the fifth and the sixth rolling stands 20-5, 20-6 by the time t 2  seconds (t 2 >t 1 ); as a result, the secondary fracture is generated between the fourth rolling stand 20-4 and the fifth rolling stand 20-5.

Title: Servo mechanism of magnetic recording and reproducing device
Inventor: YOSHIDA MASAYUKI
IPC: G11B15/60
Filed: 1983-03-24
Abstract: PURPOSE:To eliminate a track shift and the damage of a tape in a reproduction mode by controlling the press-contact distribution of a pinch roller by a signal which detected the change of the tape running position to the gap of a sound record/reproduction head, then holding the tape at its normal position. CONSTITUTION:When a tape 1 is driven with press-contact to a capstan 2, the shaft 5 of a pinch roller 5 pierces through slits 7a and 7b of a support frame 6. A yoke 8 and a magnet 9 are fixed at the upper and lower parts of the shaft 5 respectively, and the coils 10 are inserted to these yoke 8 and the magnet 9 with no contact. If the tape 1 has an upward shift, the contact width of a track 1a increases to a magnetic gap 14a of a magnetic head 14. Then the signal fed from a detector 13 is supplied to the coil 10, and a magnet 9a is adsorbed in the direction separated from the capstan 2. Thus the shaft 5 tilts, and the tape pressing force of the roller 3 is increased at the lower part. Then the tape 1 is pulled downward and reset to its normal position. Thus it is possible to eliminate both a track shift and the damage of a tape such as a one-side extension, etc.
