Title: Video camera
Inventor: TANIGUCHI KAZUYUKI
IPC: H04N5/225
Filed: 1988-06-30
Abstract: PURPOSE:To prevent deficiency of sharpness correction quantity with a decreased gain or deterioration in the S/N with too much sharpness caused with an increased gain by providing a switch means controlling the gain of an input video signal and switching the sharpness correction in interlocking with the switch means. CONSTITUTION:The gain of an amplifier 5 is switched into 3 stages such as 0dB, 9dB and 18dB by a control signal S1 from a controller 6. The gain is set by a switch 14. The sharpness correction is switched in interlocking with the switch 14. With the gain of a luminance signal and a chrominance signal increased, then the sharpness correction quantity is decreased and with the gain of a luminance signal and a chrominance signal decreased, then the sharpness correction quantity is increased. Thus, the deterioration in the S/N is prevented when the gain is increased and no deficiency in the sharpness correction is avoided when the gain is decreased thereby obtaining a sharp pattern.

Title: Loopback test control circuit
Inventor: FUNAE HIDEAKI
IPC: H04L69/40
Filed: 1986-07-14
Abstract: PURPOSE:To prevent such a case where a transmission line is looped back by mistake by detecting the coincidence between the received data and a loopback code even at a time point immediately after an executing mode is released for a loopback test carried out by a remote control at the side of the transmission side. CONSTITUTION:A coincidence detecting circuit 6 detects the coincidence between the received data and a return code in a loopback test mode set at the side of a transmission line. When a test executing mode set by a remote control is released, a signal 1a is set at an L level and a monostable multivibrator 7 works to produce a pulse 1e. The length of the pulse 1e is set larger than the data length. Thus a pulse is outputted from the multivibrator 7 even at a time point immediately the test executing mode is released as long as the loopback code is detected. Then said pulse controls a loopback code generating circuit 3 to prevent the generator of codes.

Abstract: PURPOSE:To obtain a radio wave absorber which has oblique incident characteristic of important TE wave as an absorber for a radio wave dark chamber inner wall by providing a low dielectric layer on the front face of a ferrite absorber, and laminating a conductive sheet on the front face of the dielectric. CONSTITUTION:A structure in which a ferrite absorber layer 4, a low dielectric layer 5 and a conductive sheet 6 are laminated on a metal plate 3 is provided. As an incident angle theta is increased, an admittance YF as seen from the surface of the ferrite is deviated from matching. An admittance Yc as seen from the surface of the layer 5 is rotated at the center of a Smith's chart as an axis at a point q. However, the dielectric constant of the layer 5 is approx. 1. It is assumed that an impedance Yi as seen from the surface of the sheet 6 is such that a conductive sheet is sufficiently thin for the wavelength and its admittance Y is given by Y=G+jB, it is provided by Yi=Yc+G+jB. Accordingly, the admittance P of the ferrite absorber at an oblique incident can be converted to a matching point by regulating the rotating angle of the thickness (d) of the layer 5 and admittance of the sheet 6.

Abstract: PURPOSE:To enable even a hard copy device of black/white display to perform the copying work regardless of a combination of background colors, etc., by realizing a display the combined characters of background and character colors even to a device which can discriminate only an achromatic color or a single chromatic color. CONSTITUTION:A combination character or pattern of background and character colors can be displayed also on a device which can discriminate only an achromatic color or a single chromatic color. For instance, a screen 3A using the combination of background and character colors is displayed at a display device 3.

Thus a program which rewrites a bit having designation of a background color to a bit having no background color is turned on by the screen 3A under display to perform bit processing. Then a hard copy request is fed to a hard copy device 4, and the bit having designation of background undergoes automatically the second bit processing after a copy is delivered. Then the screen is restored to the screen 3A having designation of a background color.
