Abstract: PURPOSE:To integrate a memory line, a timing circuit and a latch circuit or the like and simplify a peripheral circuit by using minority of line memories when a signal processing of an NTSC system is performed, and making separation of the luminance and the chromaticity and interlace conversion possible. CONSTITUTION:An analog video signal AV1 is A/D converted 51, a digital converted digital video signal DV1 is added to a switch circuit 52 and the signal DV1 is divided into the odd number and the even number line data by a control of a timing generating circuit 61. The divided line data is written in the respective first and the second line memories 53, 54 under the control of the circuit 61 and during reading thereof, it is executed four times repetitively for a line unit at a speed twice that of the writing. The output of the memories 53, 54 are added by an adder 57 and subtracted by a subtracter 58. A polarity of the output of the subtracter 58 is inverted by a polarity change over circuit 59 and the output is outputted. By using minority of memories 53, 54, separation of the luminance and the chromaticity and interlace conversion is made possible.

Title: Picture image reader
Inventor: MACHINO HITOSHI
IPC: H02P8/38
Filed: 1989-08-02
Abstract: PURPOSE:To simplify a device by locating a reference position and judging whether or not step-out of a stepping motor has occurred, with a single optical scanning system entry detecting means, in the drive control of an optical scanning system. CONSTITUTION:A single BL sensor 12 which becomes OFF by the entry of an indication flag 13 fixed in the scanner 6 of a picture image reader is provided for the positioning of the scanner 6. The position where the output signal of the BL sensor 12 changes from OFF to ON is the home position of the scanner 6.

As the output signal of the BL sensor 12 becomes OFF by an abnormal count of the drive pulse, step-out of a stepping motor 3 can be detected. In this way, it becomes possible to control positions and detect step-out with a single EL sensor.

Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To avert the occurrence of the temp. distribution of an optical waveguide due to the heat generation of an absorber of surface acoustic waves and to prevent the increase in the side lobe of the band characteristics of a wavelength filter by disposing a reflector on a propagation path of the surface acoustic waves and disposing the absorber for absorbing the surface acoustic waves reflected by the reflector on the outside of the optical waveguide. SOLUTION: The surface acoustic waves 10 are excited on a substrate 11 corresponding to the optical waveguide 2 by the electric energy impressed on an excitation electrode 3 and are propagated along the optical waveguide 2. These surface acoustic waves 10 are respectively reflected by a reflection electrode 7 and a reflection electrode 6, thereby, the progressing direction is changed and are progressed as the surface acoustic waves 12 and the surface acoustic waves 11. The optical waveguide is no longer constituted in the changed direction, and therefore, the surface acoustic waves are absorbed by disposing the absorber 5 and the absorber 4 in the suitable positions and eventually the influence that the generated heat exerts on the optical waveguide 2, is minimized.
