Abstract: PURPOSE:To raise the quantity of light at the time of a return-motion and to erase a residual inter-image image, by providing a slit exposure original scanning start and end position detecting means and an exposure lamp light quantity variable means. CONSTITUTION:As for an inter-image image generated at the time of a return- motion after scanning when executing the slit exposure, the ground of an original and the line picture part are integrated continuously within the slit width, and the density becomes higher than the integrated original ground. It is proportional to a picture area in the original and the density, and usually the reflection factor becomes 10-20% lower than that of the ground part. Accordingly, when the quantity of light of an exposure lamp is increased about 20% or more at the time of a return-motion, the inter-image image becomes density of the ground part or below and is not generated as fog. From the point of time when an exposure scanning start position detecting switch S1 of the original is stepped, the going-motion scanning is started, is ended by a switch S2 of the end and is shifted to the return-motion scanning, from which the quantity of light of the lamp is increased about 20%.

IPC: G09G3/36
Filed: 1990-05-22
Abstract: PURPOSE:To obtain a power source for driving a liquid crystal display whose power consumption is low and which generates stable voltage by allowing a grounded-collector type transistor circuit to generate at least the voltage at a non turning-on level which is applied to an electrode on a side for controlling turning-on/non turning-on out of electrodes opposed to a liquid crystal display body. CONSTITUTION:The grounded-collector type transistor circuit is allowed to generate at least the voltage at two levels out of the generated voltage at six levels. The voltage V2(17) at the non turning-on level is impressed on a base terminal as the voltage obtained by dividing VEE voltage nearly equal to the voltage V2 which is to be obtained by resistances(10-14). Then, a collector terminal is connected to a ground level(9), and the voltage is outputted between an emitter terminal and the VEE voltage(8) by a grounded-collector type transistor amplifier circuit by a PNP transistor(1) to which a resistance(13) for stabilizing a load is connected. In the same way, V3(18) is outputted by the grounded- collector type transistor amplifier circuit by an NPN transistor(2). Thus, the circuit whose power consumption is lower than the conventional power source circuit for the liquid crystal display is constituted.

The signal 2 shows the output balance of the right and left photo-detecting parts, namely, the inclination of the measured object in an X direction with the dividing line 8Y as a border. The signal 3 shows the output balance of the upper and lower photo-detecting parts, namely, the inclination of the measured object in a Y direction with the dividing line 8X as a border. Accordingly, when adjustment is executed so that the signal 2 and 3 can be 0, the squareness of the measured object to an optical pick-up can be exactly set.

Filed: 1992-05-25
Abstract: PURPOSE:To simplify an installation work of a tape-like body on a cable and to reduce the weight of a device by winding the tape-like body including magnetic powder around the cable. CONSTITUTION:A noise elimination filter 10 is constituted of a tape like body including magnetic powder. The filter is wound round a cable 1 and then is installed. The tape- like body-constituted noise elimination filter is formed of vinyl chloride resin, etc., with ferrite powder mixed in. Therefore, a magnetic flux is generated in the ferrite powder in the tape-like body by causing a noise current to flow in the cable 1, and then an impedance is generated due to this magnetic flux and a noise is eliminated by this impedance. It is also possible that the cable 1 is rolled several times and the tape-like body is inserted into the rolled cable and is wound and the position of the noise elimination filter is fixed by tightening up the cable. Therefore, it not necessary that the noise elimination filter is inserted from an end of the cable and is fixed at an installation position. The tape-like body which has the length corresponding to the plurality of the noise elimination filters can be wound round a core, etc., to be stored. By this method, the width of the tape-like body and the winding amount can be adjusted easily and the filter can cope with various kinds of noises.
