Title: Head switching device
Inventor: KATAOKA KAZUHIRO
IPC: G11B5/027
Filed: 1983-03-24
Abstract: PURPOSE:To attain the switching between a normal reproduction head and a still picture head by providing a switching transistor (TR) which controls the bias to the base of a TR of the first stage connected to the still picture reproduction head as well as another TR of the first stage connected to the normal reproduction head. CONSTITUTION:In a normal reproduction mode an H signal is applied to an input terminal 17. Thus both TRs Q5 and Q6 are turned on, and the DC voltage fed back by resistances R6 and R10 is applied to the base of a TRQ1 connected to a head 1. Thus the TRQ1 is turned on, and the reproduction signal is supplied to a following amplifier circuit. In a still picture reproduction, an L signal is applied to the terminal 17 to cut off both TRs Q5 and Q6 with a TRQ7 turned on. Therefore the TRs Q1 and Q2 are turned off and on respectively, and only the still picture reproducing signal is amplified. The normal or still picture signal reproduced by a head switch circuit 14 is switched for every field and extracted as a head amplifier output. Thus it is possible to switch heads with no variation of a resonance point nor a contact defect.

Title: Method for cooling continuous cast bloom
Inventor: KITADE SHINICHI
IPC: B22D11/16
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a cooling method, with which the surface flaw caused at the cooling of a continuously cast bloom is prevented. SOLUTION: When the bloom 3 is cast with the continuous casting, the cooling speed at the corner parts of the bloom 3 in the range of 5 m below a mold 2 from just below the mold 2, is controlled between 0-0.12 deg.C/s by using an insulating material or utilizing a heat source, such as gas, electricity, high frequency induction current. The portion except the corners is not executed to insulate the heat. Then, in the bloom 3 executing the heat insulation at the corner parts, austenite crystal grain diameter is uniformized over the whole surface of the bloom 3 and proeutectoid ferrite is not caused by excess-cooling. Such a bloom 3 is cooled by using a bloom forcible cooling device of a bloom cooler 5, etc., and thus, the uniform cooling of the bloom 3 can be obtd. and the internal stress at the cooling time is reduced.

Abstract: PURPOSE:To bend a blank pipe material and to form an axial groove to said material by mounting the blank pipe material onto a pair of mandrels and using knife-shaped bending punches. CONSTITUTION:The rear surfaces of a pair of mandrels 10, 10 facing apart from each other contact sliders 11 via a blank material 15. Punches 12, 12 are disposed in the direction orthogonal with the mandrels 10, 10 and both are made movable toward the center. The punches 12, 12 are moved toward the center by the 1st cams 13, 13 to work the blank material until the V bending angle theta thereof attains about 90 deg.. The sliders 11, 11 are moved in the central direction by the 2nd cams 14, 14 while the punches 12, 12 are held intact to form the above-mentioned bending part into a groove shape via the punches 12, 12. The axial groove width of the material 15 is thus made freely changeable by changing the thinkness of the punches 12, 12.

Title: Fm demodulating circuit
Inventor: UBUSAWA YUTAKA
IPC: G11B20/06
Filed: 1982-03-30
Abstract: PURPOSE:To obtain a distinct picture, by providing a variable equalizer for detecting a component in the vicinity of center frequency of an FM demodulating signal and responding to it, and an FM detecting means whose level in the vicinity of center frequency is increased or decreased by the equalizer. CONSTITUTION:A regenerating video signal S1 is inputted to an equalizing amplifier 3 after a luminance signal SY is separated by an HPF 2. This output is inputted to a variable equalizing amplifier 9, is brought to an equalizing measure, and is sent as a luminance signal S'Y to a detector 4 from an output terminal 9b. At the same time, S'Y is inputted to an envelope detector 11 through a BPF 10, and when a level of a control signal SV outputted from said detector increases, a transfer constant F (omega) becomes large by operation of the variable equalizing amplifier 9. When F (omega) becomes large, by vicinity of 4.27MHz of S'Y is attenuated by a trap function as shown in the figure. When the level of the control signal SV drops, F(omega) becomes small, and it is amplified by a resonance function. In this way, a variation of amplitude of the FM luminance signal S'Y in the vicinity of apparent center frequency can be suppressed, and spuriousness is suppressed, by which a stable video can be obtained.
