IPC: H04N9/83
Filed: 1985-03-21
Abstract: PURPOSE:To realize a frequency conversion processing by a simple circuit construction by sample-holding a chroma signal at a specific timing, and carrying out demodulation, frequency conversion and modulation. CONSTITUTION:Respective timing signals in which a phase is locked are formed by locking the phase with a color subcarrier in a timing generating circuit 10, and formed by an operation such as a frequency dividing and multiplying.

Title: Detector for tension of wire extension car
Inventor: NAKA TAKAO
IPC: G01L5/04
Filed: 1980-04-30
Abstract: PURPOSE: To detect tension in high accuracy by simple structure by a method wherein a tension detector is mounted only to one bearing separated from a wire drawing location, and wire extending tension is detected from a shaft moving using the other bearing location as a fulcrum.  
     CONSTITUTION: One bearing 4 at the wire extending side separated from the drawing side of a wire 5 is made slidable, and a tension detector 6 is installed while a roller chain 7 connecting a sprocket 3 and a speed reducer 8 is drawn out from the sprocket 3 at a right angle in the detecting direction by the tension detector 6 by means of a guide sprocket 9. According to said constitution, bearing 4 at the sprocket 3 side functions as a fulcrum by the tension of the wire when the wireis extended, and a shaft 2 is moved at the bearing 4 side of the tension detector 6 side, thus detecting tension. Tension can be detected in high accuracy because a tension detecting section is far from a back tension functioning location and is hardly subject to the effect.

Title: Releasing device and method thereof
Inventor: RARUSU KAARUSON
IPC: B65D5/72
Filed: 1985-03-22
Abstract: Opening arrangements for packing containers often comprise a prepunched hole which is covered by a tear-off cover strip. To facilitate the pouring out of liquid contents a so-called pouring rim is frequently present too, that is to say a material strip which forms a projecting rim over which the contents can run. The application of the pouring rim as well as the manufacture of the opening arrangement as a whole are facilitated by joining in advance the pouring rim in a detachable manner to the cover strip, whereafter the cover strip and the pouring rim can be applied as a unit.

Title: Input circuit
Inventor: MIYAGAWA YOUICHI
IPC: H03K19/0948
Filed: 1982-04-07
Abstract: PURPOSE:To reduce and stabilize the current of an input circuit, by inserting a resistance between an input terminal and a power supply terminal in a detecting circuit which detects the state of the input terminal synchronously with a control signal. CONSTITUTION:The state of an input terminal 2 is detected by a detecting circuit consisting of FET7-9 and synchronously with a control signal 3. The output of an inverter 5 which is supplied to the subsequent circuits is set at a low level while a signal of a high level is applied to the terminal 2. An FET9 is turned on only when the signal 3 is kept at a high level. The value of a resistance 10 is set sufficiently larger than the ON-resistance of the FET9. Thus the current of the FET9 depends on the value of the resistance 10 and can be set at a small and stable level. When the signal 3 is set at a high level in case no input is applied to the terminal 2, the output of the inverter 5 is set at a high level. This state is kept thereafter. Thus the current consumption becomes zero for the input circuit which is shown in the diagram.

Title: Recording liquid
Inventor: KOIKE SHIYOUJI
IPC: C09D11/328
Filed: 1982-04-09
Abstract: PURPOSE:To provide a recording liquid which has prolonged continuous recordability and discharge stability after long-term recording suspension and is suitable for use in writing utensils and ink jet recording, containing a specified monoazo compd. CONSTITUTION:0.5-20wt% compd. (dye) of the formula [wherein R1, R2, R3, R4 are each H, halogen, OH, SO3M (M is alkali metal, ammonium, amine), NO2, CH3, OCH3; R5, R6, R7, R8 are each H, OH, SO3H with the proviso that at least one of them is always OH] is dissolved in a recording liquid. Since the compd. has an azo linkage in the molecule, it can be thought that even when the recording liquid is instantaneously exposed to high temperature above 250 deg.C in a thermal action part in a recording head and the compd. is decomposed, the molecular chain is mainly broken at the azo linkage part. Therefore, the decomposition products of the compds. are relatively stable per se and have highly hydrophilic groups so that they are highly soluble in the recording liquid. Thus, stable recording becomes possible without forming precipitates.

Abstract: PURPOSE:To permit both fine boring and formation of an oxide coating at the surrounding of the bored fine hole to be concurrently effected through a local heating by a method wherein a laser beam with energy absorbable by silicon materials is irradiated under the oxygen atmosphere or that containing oxygen. CONSTITUTION:A laser beam from a source 4 is focused by a lens 5 to be irradiated onto a substrate 6 made of silicon, the substrate being mounted on a manipulator 7 to permit such irradiation. All of these components are set under the oxygen atmosphere. By using an argon laser with a wavelength of 1,000nm and output of 4-6W class as the laser source 4, a fine circular hole 6a of 10- 100mumphi is formed at a proper location in the peripheral part of the substrate 6. Boring under the oxygen atmosphere leads to local heating for a short time under the oxygen atmosphere, whereby a thin oxide coating 8 is formed only at the peripheral part of the fine circular hole 6a which part becomes the local high-temperature portion corresponding to the irradiated part of the laser beam. The coating 8 can be easily removed by immersing it in a diluted etching solution adapted for oxide coating.

Abstract: PURPOSE:To decrease the capacity of a mapping ROM by amplifying 2-axis digital signals subjected to orthogonal detection respectively and outputting other signal in M-bit to a storage device if either absolute value of the amplified digital signals overflows. CONSTITUTION:The 2-axis digital signal in N-bit length subjected to orthogonal detection is inputted respectively to amplifier circuits 10, 11 and amplified according to the gain of a variable gain device 4.
