Title: Amplitude detecting circuit of vertical deflection signal
Inventor: KIKUCHI MASAFUMI
IPC: H04N3/223
Filed: 1984-05-29
Abstract: PURPOSE:To improve the response by providing a level decision circuit deciding that the amplitude of a sawtooth wave voltage of vertical period is within a proper range and a counter whose count operation is directed either in increment or decrement direction by means of the signal from the said circuit. CONSTITUTION:A vertical sawtooth wave voltage appearing at an output of a vertical oscillation circuit 2 is fed to amplitude detection circuits 5, 6. The circuit 5 compares an amplitude Ev of the sawtooth wave voltage with a reference voltage VT1 and the circuit 6 compares the Ev with a reference voltage EV2. A level decision circuit 7 to which the detection signal of the circuits 5, 6 is fed decides the level only during the vertical blanking period of the signal fed from a terminal 8. A detected output of the circuit 6 is fed to an up-down counter 9 as a signal controlling the incremental/decremental counting operation. A gate circuit 11 is turned on when a decision output of the circuit 7 is at H level and turned off when L. An output of the counter 9 is fed to a D/A converter 12, where it is converted into an analog control voltage Vc, and it is fed to the circuit 2 as a correction signal.

Title: Magnetic disk device
Inventor: OSADA MOTOYUKI
IPC: G11B25/04
Filed: 1982-06-25
Abstract: PURPOSE:To prevent the mixture of dust into a head part and the generation of a head crush fault, by setting the head part into a sealed room so as not to expose the head part to the outside air when a disk cartridge is loaded and unloaded. CONSTITUTION:A magnetic head 6 is shifted toward an arrow A2 and set at its home position when the record/reproduction processing is over. Then a disk cartridge 2 is removed. The pushing pressure of a push-button 12 is released with removal of the cartridge 2. Then a slide plate 11 is slid toward an arrow D2 by the tension of a spring 16 to close an aperture part 10. When the plate 11 is closed when the cartridge 2 is loaded and unloaded, the area of a head 4 is shielded from the outside air by means of screens 10A, 10B, 10C and 10D as well as the plate 11. Thus the head 4 is never exposed to the open air. This prevents attachment of dust to the head 6, etc.

Title: Constant current circuit
Inventor: MATSUMOTO KOICHI
IPC: H03F3/343
Filed: 1989-04-29
Abstract: PURPOSE:To obtain a circuit having an optional current ratio independently of a DC amplification factor of a PNP transistor(TR) by connecting a P-channel MOSFET between the base of a current mirror pair comprising PNP TRs and an earth terminal. CONSTITUTION:A P-channel MOSFET 7 is connected between bases connecting in common of PNP TRs 4, 6 being components of a current mirror pair and an earth terminal. Since no DC current flows to a gate of the FET 7, the relation of a current Ic1=Ir exists. Thus, the gate-source voltage is varied automatically depending on the increase/decrease in the current amplification factor of the PNP TRs 4, 6, and a ratio of the reference current Ir to a collector current Ic2 of a TR 6 keeps a constant value. Thus, an optional current ratio is obtained independently of the transistor current amplification factor.

Abstract: PURPOSE:To produce a sliding member which is formed of a hard nitrided layer on the surface and has high abrasion resistance by applying a nitriding treatment to an Fe-base sintered alloy contg. a small amt. of Cu. CONSTITUTION:Iron powder, natural graphite powder, and electrolytic copper powder of <=100 mesh as well as zinc stearate as a lubricant are mixed, and after the mixture is pressurized and molded in dies, the molding is sintered at 1,150 deg.C in an ammonia cracking gaseous atmosphere to a sintered body consisting of 0.3-2.0% C, 3-10% Cu and the balance Fe. The sintered body is nitrided by a gasoues nitriding or gaseous soft nitriding treatment. Since such sintered body contains Cu, a hard nitrided phase of gamma'(Fe4N) is easily formed on the surface thereof, whereby abrasion resistance is improved, thus the sliding member having high abrasion resistance is obtained by such treatment as well as with the lubricating oil contained in the pores of the sintered body.

Title: Telecine device
Inventor: ISHIDA TAKEHISA
IPC: H04N5/257
Filed: 1984-05-30
Abstract: PURPOSE:To convert the picture of a cinefilm having any driving speed and any aspect ratio into TV pictures of high quality, by using a deflecting means which gives the auxiliary deflection due to a scan to a light spot of a laser beam in the film driving direction and according to the driving speed of the film as well as the frame length on the film in its driving direction. CONSTITUTION:The auxiliary deflection is not needed with a standard format; while the auxiliary deflection is applied with the forward polarity in the case of a wide format. In case a cinefilm is driven reservely at the speed of every 24 frames per second, the digital video signal obtained by picking up a film picture is written to a frame memory. In such a case, the order of writing memory addresses is reversed to the forward drive mode. At the same time, the polarity of the auxiliary deflection is also reversed. In a low-speed drive mode, the polarity of the auxiliary deflection is reversed to the normal speed of 24 frames per second since the film driving distance is short within a 2-field period. While the amplitude is made coincident with the picture height in the format of the film picture.
