Title: Biaxially oriented film manufacturing apparatus
Inventor: WATANABE JIYUNKICHI
IPC: B29L7/00
Filed: 1983-10-13
Abstract: PURPOSE:To form a biaxially oriented film with an inveriably high profitability quickly adapting to changes in marketing conditions by combining more than one system of unstretched film manufacturing equipment with respect to one system of biaxially stretching equipment. CONSTITUTION:Two systems of unstretched film manufacturing equipment such as a single layer unstretched film manufacturing equipment and multilayer unstretched film manufacturing equipment are combined with one system of a biaxially stretching equipment. In this manner, more than one system of unstretched film manufacturing equipment are laid out with respect to one system of biaxially stretching equipment which requires a large equipment cost and floor installation area. When the type and brand of the film is changed, most of work involved concentrates on the unstretched film production process. Therefore, the installation of unstretched film manufacturing equipment in more than one system makes the other system of the equipment ready for other type and brand while one system of equipment is used to produce a film of a certain type and brand thereby enabling the alteration of the type and brand freely with limited loss of time.

Filed: 1990-07-20
Abstract: PURPOSE:To make the scan of a light deflector coincident with that of an image pickup device and to remove an influence caused by the drift of a scanning mechanism by controlling the scan of the image pickup device based on a signal from the output side of the scanning mechanism. CONSTITUTION:A sensor 4 is arranged in the vicinity of the turning shaft of the galvanometer mirror of the synchronous scanning microscope, and the turning position of the galvanometer mirror is detected. The output value of this sensor 4 is transmitted to a circuit 6 for synchronous scanning as a position signal, and this signal and a signal for synchronization with the scan of a light deflector 3 are transmitted to an image desector tube 5. Thus, since the deflection control of the image desector tube 5 is executed based on the output signal of the sensor 4, the scan can be coincident to that of the light deflector 3 precisely, almost the peak value of the photoelectronic density of photoelectronic flow to irradiate an aperture board 5d can be fetched into an aperture, and diffused light can be efficiently removed.

Title: Light source device for illumination
Inventor: SENGOKU MASAYUKI
IPC: G03B27/72
Filed: 1982-11-04
Abstract: PURPOSE:To correct automatically an illuminance distribution by installing plural pieces of photoelectric detectors on a photomask or reticule, detecting simultaneously the intensity of illumina at each point, determining the difference between the outputs of the detectors, and driving the motor in the position X-Y-Z direction of the light source so as to minimize the difference thereof. CONSTITUTION:A light source 2 is held by a support base 1 which is made slightly movable by means of a driving motor 10 in an X or Y direction. The light from the light source 2 is condensed by an ellipsoidal mirror 3 and is converted by a condenser lens 4. The converted luminous flux illuminates a photoelectric detector 5 constituted of plural sensors and at the same time the intensity of illumination at each point is detected. The intensity of illumination signal detected photoelectrically is amplified by preamplifier circuits 6 and 7, and is inputted to a differential amplifier 8, the differential output signal wherefrom is made into a motor driving voltage by a motor driving circuit 9 to drive the motor 10 in the X or Y direction. The motor is stopped when the differential output between the sensors attains the voltage within a certain specified voltage. The uneven intensity of illumination is thus automatically corrected within the certain specified value.

Abstract: PURPOSE:To limit a short-circuit current by providing a thyristor connected between control terminals of a control transistor (TR), operated based on a current flowing to a resistance voltage division circuit and keeping the control TR to a conductive state so as to turn off surely a current limit TR. CONSTITUTION:If an overcurrent flows to a load or the load is short-circuited, a large current flows to a protection circuit 14, a drain-source voltage of an FET1 is increased, a base voltage of a TR3 divided by resistors R4, R5, and R6 is also increased, the TR3 is turned on, the gate voltage of the FET1 is decreased, the FET1 is turned off and the short-circuit current is interrupted. After the TR3 is turned off, when a voltage across the resistor R5 by a voltage divided by the resistors R4, R5 and R6 reaches a prescribed value or over, the thyristor 9 is turned on. Then, the base bias resistance of the TR3 is decreased from the initial state from the next half cycle of the shortcircuit, the TR3 is turned on when the voltage between the terminals A and B is increased slightly, the FET1 is turned off thereby decreasing remarkably the current flowing to the FET1.
