Patent JP-H0372304-A (JP)
Title: Manufacture of optical coupler
Inventor: NAGATA KAZUHITO
IPC: G02B6/255
Filed: 1989-08-11
Abstract: PURPOSE:To forming a large uniform fusion area which has a nearly ideal coupling efficiency and to miniaturize an optical coupler by controlling the quantity of heat given to an optical fiber in reciprocal motion by varying the quantity of heat of a heating source or the distance between the heating source and optical fiber. CONSTITUTION:A burner 12 is used as the heating source 12, which is put in the reciprocal motion in the direction of the optical fiber axis and so controlled that the gas flow rate of the burner is small in the center of the reciprocal motion to obtain the least quantity of heat generation and increased toward both ends of the reciprocal motion to obtain the larger quantity of heat generation, thereby making the quantity of heat given to optical fibers 13a and 13b substantially weak in the center of the reciprocal motion and larger toward both the ends. Both ends of the optical fibers 13a and 13b are applied with mutually equal constant drawing forces at all times. As the area which is thinned in diameter by drawing is expanded, the heated area becomes wide, so the amplitude of the reciprocal motion of the heat source 12 is increased gradually as the frequency of the reciprocal motion is increased. Consequently, the effect of thinning of the optical fiber diameter is prevented from being converged on the center, the area which is thinned in diameter relatively uniformly is formed large, and the coupler is nimiaturized.

Title: Voltage comparator
Inventor: IMAIZUMI EIKI
IPC: H03K5/08
Filed: 1985-09-25
Abstract: PURPOSE:To improve the comparing velocity of a fine voltage difference by adding a positive feedback circuit between the input terminal of an inverter 1 and the output terminal of an inverter 2, and sufficiently amplifying the voltage. CONSTITUTION:When switches SW1-SW3 are closed to apply one input V1 to a capacitor C1K, inverters 1, 2 are self-biased to logic threshold voltage VLT. Since the voltages of both terminals of a feedback circuit 3 become equal, the circuit 3 does not operate. Then, the switches SW2, SW3, SW1 are opened, a switch SW4 is closed, and other input V2 is applied. In case of V2>V1, the voltage of the input terminal of the inverter 1 rises, and the voltage of the output terminal of the inverter 2 also rises. When the difference between the input voltage of the inverter 1 and the output voltage of the inverter 2 arrives at Vth, the circuit 3 operates, and the input voltage of the inverter 1 and the output voltage of the inverter 2 abruptly become high level voltage. In case of V2<1, it reversely becomes low level voltage.

Title: Hysteresis comparator circuit
Inventor: KUROSAWA YUJI
IPC: H03K3/023
Filed: 1987-08-26
Abstract: PURPOSE:To facilitate the setting of the width of a hysteresis voltage by providing two variable current sources, a current switch switched in response to an output of a comparator circuit and a current polarity inverting means. CONSTITUTION:The current switch S1 changes over whether an output current of the 1st variable current source I1 is supplied to a noninverting input of the comparator circuit 2 via a resistor R1 or supplied directly in response to an output of the comparator circuit 2. Moreover, a current mirror 1 receives an output current of the 2nd variable current source I2 and outputs a current inverting its polarity to a noninverting output of the comparator circuit 2. Since the hysteresis comparator is formed in this way, the width of an optional hysteresis voltage is set easily by having only to control the output current of the 1st and 2nd variable current sources I1, I2.

IPC: B29B11/16
Filed: 1993-08-25
Abstract: PURPOSE:To accurately remove an unwanted prepreg without adversely affecting a wanted prepreg by a method wherein a prepreg of a prepreg tape is precut, the unwanted part is dividedly cut into predetermined sizes and shapes, and the divided parts are removed from release paper in a predetermined order in a predetermined direction. CONSTITUTION:In forming a sheet 1 by laminating prepregs 12, for example, in the order of A-F in the direction of arrows, the shape of the prepreg 12 can be evaluated as a coordinate on a horizontal table of a cut-off device. The coordinate is converted to a coordinate on a prepreg tape 2 in the reverse order of lamination. Since the prepregs are disposed showing down in a laminate head, the data is reversed upside down with respect to the center line of the tape 2. Data of an unwanted shape 4 is formed from data indicating a wanted shape 3 on the tape 2. After that, data for dividing the unwanted part 4 into removable shapes is formed. Next, a removing direction and a removing order are determined. An operation command of cutting the unwanted part into divided unwanted shapes is generated. Lastly, a command of removing the unwanted area is generated.
