Title: Color television system and its device
Inventor: MATSUI KAZUMASA
IPC: H04N11/00
Filed: 1987-03-04
Abstract: PURPOSE:To improve compatibility with an NTSC system or the like and to expand the band of a color difference signal by moving the high frequency component of one color difference signal out of two to a band upper than a carrier chrominance signal of the NTSC system and multiplexing these signals to obtain a composite TV signal. CONSTITUTION:The frequency component upper than the band regulated by a NTSC system out of an NTSC system narrow band color difference signal Q is converted and multiplexed on a frequency band upper than the carrier color difference signal of a wide band color difference signal I and the frequency of a border between the high frequency component of the Q signal and the chrominance signal of the I signal is set up in accordance with the band of a transmission line. Since the high frequency component of the Q signal is multiplied on the band upper than the chrominance signal of the I signal, it is unnecessary to sharply change the NTSC system chrominance signal component. Thus, the picture quality such as resolution can be improved by expanding the bands of the I and Q signals while keeping the compatibility with the NTSC system.

Title: Later zipping type drill chuck
Inventor: GIYUNTAA HORUSUTO REEMU
IPC: B23B31/12
Filed: 1980-04-14
Abstract: A chuck has a chuck body formed centered on the chuck axis with an annular array of outwardly directed teeth. A plurality of generally angularly equispaced and radially displaceable jaws on the body can be displaced toward and away from each other by means of a tightening sleeve which is rotatable on the chuck body about the chuck axis. A ratchet pawl is pivoted on this sleeve and has an end engageable with the teeth in a direction so as only to allow rotation of the sleeve and chuck relative to each other in a direction moving the jaws toward each other. A spring is braced between this pawl and the sleeve and urges the sleeve into radial engagement with the teeth. A release ring can be rotated relative to the chuck body between a holding position which allows the spring to press the end of the pawl against the teeth and a releasing position which holds the end of the pawl out of engagement with these teeth.

Title: Range-finding device for passive automatic focusing device
Inventor: ISHIGURO MINORU
IPC: G03B13/36
Filed: 1991-02-22
Abstract: PURPOSE:To surely obtain distance data without affecting by unstable brightness distribution, to surely enable focusing and to accurately and quickly measure a distance to the object even when the plural objects exist. CONSTITUTION:The object is caught by a light receiving sensor consisting of three line sensors 10b, 20b and 30b. The output signal value of the secondary difference of the brightness distribution is divided into three or more level areas. Then, a zero-cross point when a signal is changed to the level areas which are not adjacent and when such change occurs within the range of the prescribed number of picture elements of the light receiving sensor is calculated. Simultaneously, it is detected whether the zero-cross point is one when the secondary difference is changed to negative from positive or one when the secondary difference is changed to the positive from the negative. Then, the coincidence of three zero-cross behavior is detected while two zero-cross behavior among the zero-cross behavior related to three line sensors 10b, 20b and 30b is properly shifted with one line sensor among three line sensors as a reference. Based on the shift quantity of the zero-cross behavior of two line sensors when they coincide, the distance to the object is measured.

Title: Screw fluid machine
Inventor: SASAKI SHIGERU
IPC: F04C18/16
Filed: 1983-03-25
Abstract: PURPOSE:To decrease the transmission error of a timing gear, reduce the clearance between rotors, and obtain a single-stage oil-free screw compressor with high performance and high reliability by adjacently arranging a radial bearing and the timing gear. CONSTITUTION:A thrust bearing 70 of a male rotor 1 is arranged at the end of an axis adjacently to the drive side, i.e., a pinion gear 11. The thrust force of a female rotor 2 is supported by an angular ball bearing 60 of the suction side. Accordingly, timing gears 9, 10 can be arranged adjacently to a radial bearing 6 of the discharge side. Thereby, an increase of the end surface clearance during operation can be prevented, and in addition, the axial action can be decreased by suppressing the axial displacement of the timing gear portion to a low level and as a result, the clearance between rotors can be reduced.
