Title: Switching circuit
Inventor: YAMAGUCHI ATSUO
IPC: H03K17/60
Filed: 1978-02-02
Abstract: PURPOSE:To obtain a circuit whose switching speed is quickened sufficiently, by providing transistors for discharging and charging a speed-up capacitor respectively. CONSTITUTION:When a current flows from driver circuit 3 to the base of transistor 1 via resistor 2 to make transistor 1 conductive, the current from driver circuit 3 shunts to the base of charging transistor 7 as well to make transistor 7 conductive and the charging current of capacitor 4 flows to collector power supply 6, transistor 7, speed-up capacitor 4 and the base of transistor 1, so that the lag and rise time of transistor 1 will be shortened. On the other hand, when transistor 1 becomes unconductive, discharging transistor 8 operates to shorten the accumulation and fall time of transistor 1. The switching speed can therefore be quickened sufficiently.

IPC: H03D7/00
Filed: 1988-01-21
Abstract: PURPOSE:To simplify the BPF (band pass filter), to reduce the cost and to attain small size by attenuating or applying phase conversion to part of a signal of a local oscillator, synthesizing the result to an output signal of a mixer, cancelling the local oscillation signal included in the mixer output signal thereby preventing the leakage of the local oscillation output. CONSTITUTION:Suppose that leakage of a local oscillation signal takes place in an output of the mixer 1 and the signal at the output of a synthesizer 7 is expressed as A=a cos(omegaLtphia), and a local oscillator signal component caused at the output of the synthesizer 7 is expressed as B=b cos(omegaLtphib). The attenuation of an attenuator 5, the distribution ratio of a distributer 4 and the synthesis ratio of a synthesizer 7 are selected properly to obtain the relation of a b and the relation of phases ¦phia-phib¦ pi(180 deg.) is selected by a phase shifter 6, then the relation of A+B 0 is attained. That is, the leaked signal of the local oscillator included in the signal outputted from the mixer 1 is cancelled by a signal through the attenuator 5 and the phase shifter 6. Thus, the small size and low cost of the BPF ater attained.

Title: Binary coding device
Inventor: TAKATANI MATSUHIKO
IPC: H04N5/14
Filed: 1982-01-29
Abstract: PURPOSE:To perform a process in response to the noise component characteristics and to improve the binary coding accuracy, by dividing an image pickup screen into plural regions and setting the threshold level to each of the divided regions to carry out the binary coding of an image pickup signal. CONSTITUTION:The video signal detected by a detector 1 is amplified by an amplifier 2. One of the amplified video signals is applied to a low-pass filter 3; while the other signal is used to an input of one side of a comparator 7. A scan screen M is divided into 9 regions (3 in vertical and horizontal directions each) for example. Therefore the region of vertical (Y) direction is decided by an output PY of a Y direction divider 4; while the divided regions of horizontal (X) direction of each horizontal scanning line are decided by an output PX of an X direction divider 5. Then the part of oblique lines is detected on the screen M. The comparator 7 compares the video signal supplied from the amplifier 2 with a level signal supplied from a dividing switch 6. Thus a video signal is binary coded.

Filed: 1989-01-20
Abstract: PURPOSE:To contrive simplification of manufacture by obtaining a product tile when a molded body, which is printed thick, is burnt as it is, by printing thick unburnt raw material powder slurry on the surface of molded tile foundation. CONSTITUTION:A tile foundation body is prepared by mixing raw materials, which is press-molded into a rectangular platelike tile, to begin with. Then unglazed burning of the same is performed and then powdery slurry, which has the same composition as that of a tile foundation 12 and is unburnt, is printed thick on the surface of its unglazed pottery. Then the same is burnt, the percentage of water content of the tile foundation 12 and a projected pattern 14 part is controlled and then the surface of a burnt product is glazed. Since the projected pattern 14 part has the percentage of water content of the same extent as that of the tile foundation 12 part, therefore, water in glaze in a state of slurry is absorbed well even in the projected pattern 14 part at the time of glazing and a film of the glaze is formed favorably. Thus principal burning of a glazed product is performed and a glazed tile 10 having a relief pattern on the surface is obtained.

Title: Gas discharge panel
Inventor: SHINODA TSUTAE
IPC: H01J11/28
Filed: 1984-01-25
Abstract: PURPOSE:To eliminate the need for a mask vacuum evaporation method that will not form a protection layer and obtain gas discharge panel with high reliability by providing a conductor layer with a coarse surface as a leak electrode that leaks the wall charge cumulated on a dielectric layer. CONSTITUTION:Leak electrodes 13 and 16 are formed by coating a glass substrate located at the inside to be coated with a sealing agent when the peripheral sections of the glass substrates 11 and 15 are coated with the sealing agent while the sections are being sealed after a dielectric layer 12 is formed and simultaneously baking the glass substrates in a process where the subsequent agent is baked. The surface of leak electrodes 13 and 16 formed in such a way is at least 0.5mum or more in a difference in the recessed and protruded sections of the surface. Even when a protective layer made of MgO is formed thick on this leak electrode 13, cracks enter the inner part of the protective layer and the wall charge cumulated on the surface of the propective layer is leaked. As a result, an unstable process such as mask vacuum evaporation method for the purpose of preventing the protective layer from being formed on the leak electrode is not required.
