Title: Beat level detection circuit
Inventor: ITO SHUNPEI
IPC: H04N17/00
Filed: 1985-08-02
Abstract: PURPOSE:To perform beat level detection excluding the influence due to a video signal component which cannot be separated from a beat signal by holding a judging result obtained by comparing the beat level with a reference level of a prescribed time and preventing thejudging result from being changed even when the video signal is instantaneously or for a short time changed. CONSTITUTION:A voltage comparator 3 performs a voltage comparison between a reference voltage determined by resistance 1, 2 and a beat level and outputs the decided result. Namely, when the beat level is below the reference voltage, 'H' is outputted, and when the beat level is above the reference voltage, 'L' is outputted. To a monostable multivibrator 4 having retrigger function, a trigger is applied at the leading edge of an input shown by an arrow in the drawing, and 'H' is outputted. The output of the voltage comparator 3 and the output of the monostable multivibrator 4, since an OR logic is outputted by an OR gate 7, become largerin a beat level input, and if the output of the voltage comparator 3 does not continue to output 'L' irrespective of the largeness of a video signal component, the output of the OR gate 7, or the output of a beat level detecting circuit maintaines 'H'.

IPC: G11B20/16
Filed: 1980-12-05
Abstract: PURPOSE:To reproduce data by digital processing entirely by detecting a digital data signal rising by a window pulse which corresponds to a rise to a level H. CONSTITUTION:A window pulse 39 and a synchronous detection signal from a detecting circuit 38 are supplied to an AND circuit 40 to extract the window pulse 39 while the synchronous detection signal is at a high potential.

IPC: H04B15/00
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To optimize positions of pins of a package by minimizing signal interference due to a high frequency signal source. SOLUTION: A DBS receiver front end 400 includes a tuner chip 402 and a demodulator/decoder chip 404. The tuner chip 402 receives a reception signal, converts it into a product signal and a low pass filter 422 filters a product signal. The demodulator/decoder chip 404 provides a clock signal frequency to the tuner chip 402 to indicate a desired reception band width and converts a base band signal into a decoded signal. In the design of a package for the tuner chip 402, pins relating to high frequency signals are placed at opposite sides of the chip (in the case that two high frequency signal sources are in existence), or formed to be in a triangle form (in the case that three high frequency signal sources are in existence) whose apexes are placed apart to part the pins at a maximum distance. In the case of the latter, at least two pins are placed at corners of the package.

IPC: F16J15/08
Filed: 1988-07-12
Abstract: PURPOSE:To prevent the deformation over the specified degree for a metal O-ring containing a sectionally circular core and a metal seal member such as a gasket which is to prevent the metal core from deformation thereof by inserting the metal ring into the metal core. CONSTITUTION:In the typical example of a metal seal member 13 where the fluid pressure acts on a metal seal member 10 from the inner side to the outer side thereof, such a specific type of the metal seal member 10 is used that the surface of the metal ring 14 on the side of the internal diameter makes contact with the internal surface of a metal core 11. Therefore if a pressure may act on the metal seal member 10, the metal ring 14 prevents the seal member 10 from being deformed. Even if there is no O-ring groove 18 or the maximum strictness in both manufacturing precision and surface roughness thereof is not required, the breakdown of the seal member may be prevented.

Title: Method for formation of thin film
Inventor: ITOU TAKASHI
IPC: H01L21/31
Filed: 1982-09-30
Abstract: PURPOSE:To enable to obtain the flat surface on a substrate by a method wherein the substrate is arranged in a mixed gas atmosphere, a thin film growth reaction and an etching reaction are performed simultaneously by irradiating a beam of light, thereby enabling to lessen the unevenness of the substrate surface. CONSTITUTION:As a gas system 8, mixed gas of monosilane, oxygen and carbon tetrafluoride is used, and a substrate 3 is maintained at the temperature of 400 deg.C. Under this condition, when the above-mentioned mixed gas is introduced into a reaction chamber 1, a silicon dioxide film is grown on the substrate 3 by the reaction of SiH4+2O2 SiO2+2H2O. As the silicon dioxide film 11 has a stepping caused by a film 10, it is to be exactly formed along the stepping or in such a manner that it makes the so-called overhang. However, the CF4 contained in the mixed gas is turned to an exited state by irradiating a beam of light 9 while it is being formed, an etching is performed when the CF4 comes in contact with the silicon dioxide film and, at the same time, a silicon dioxide film 12 is formed. As the etching for the silicon dioxide film 12 is performed in the direction vertical to the substrate 3, the degree of reduction in film thickness at the stepped part is lessened, thereby enabling to reduce the stepping considerably.

Filed: 1987-07-09
Abstract: PURPOSE:To obtain an image sensing element with an amplifying function which enables miniaturization and possesses high resolution, high sensitivity and high speed operation capability, by making up a bipolar type structure wherein the electrode of a lamination-type photodiode is connected to the base of a bipolar transistor. CONSTITUTION:Image picture elements are detected by a photodiode PD, amplified by a bipolar transistor T0, and output and transferred from the collector of a transistor. An aluminum electrode on the rear of a photodiode 19 serves as a base electrode 16 of the transistor. When the image picture elements are detected by a lamination-type photodiode 19 composed of amorphous silicon, the signal is amplified by the transistor, and output and transferred from a collector electrode. Therefore an output is taken out from the rear of a substrate, and detected charge is stored in the photodiode from a junction part between collector.base. Thereby, a fine constitution is enabled, and photocurrent is reduced. Although the storage capacity is small, an element with high sensitivity is obtained, because it has amplifying function.
