Title: Phase locked loop circuit
Inventor: KOU YOSHIROU
IPC: H03L7/06
Filed: 1985-11-20
Abstract: PURPOSE:To form a continuous wave of a prescribed period oscillated in an optional frequency by inputting a ripple carrier RC signal and a synchronizing signal of a prescribed period to a load LD terminal of a counter frequency- dividing an output of a voltage controlled oscillator VCO in a PLL circuit in an oscillation circuit using a phase locked loop PLL circuit. CONSTITUTION:A signal extracted from a specific timing of a synchronizing signal is used as a control signal deciding the period of a counter 2 frequency- dividing an output of the voltage controlled oscillator VCO 3 in the phase locked loop PLL circuit. For example, in a video signal of the standard television system, a horizontal synchronizing signal and a clock of 14.13818MHz are synchronized and 910 clocks exist in one period of the horizontal synchronizing signal. Thus, in obtaining a continuous wave of nearly 2.5MHz synchronized with said horizontal synchronizing signal at each specific phase, when a count number of a counter 1 is selected as 910 and a count number of the counter 2 as 159, the continuous clocks having a prescribed frequency of 2.502MHz synchronized with the horizontal synchronizing signal at a specific phase are obtained.

IPC: G11B23/113
Filed: 1991-10-08
Abstract: PURPOSE:To enable a device to mount plural pancake reels and to make the shape of the device comparatively small. CONSTITUTION:An automatic changer 11 is arranged as a pancake reel exchanger to which at least two pancake reels 21 (22, 23) arranged in the axial direction and coaxial direction of a reel stand 20 are to be mounted. Therefore, a casing of this tape winder can only be formed so as corresponding to the amount of thickness in the axial direction of pancake reels 21 (22, 23), then the pancake reels 21 (22, 23) of more than two reels can be mounted without making the shape of the whole device larger so much.

Title: Temper mill
Inventor: KIJIMA HIDEO
IPC: B21B27/00
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of longitudinal stripes and bellows at the time of temper rolling and to efficiently manufacture ultra thin steel sheets by making the outer layer part of a work roll of a sintered hard alloy and setting the thickness of the outer layer part to a specified thickness. SOLUTION: A steel sheet 3 after annealing is again rolled with a 1st stand 1 and temper rolling is executed with the 2nd stand. The draft at the 1st stand 1 is set so as to be 20% and, as the rolling conditions at the 2nd stand 2, the elongation percentage is set to a prescribed elongation percentage of <=1%. The elongation percentage is realized by adjusting the tension on the outlet side of the steel sheet matching to rolling load. It is preferable to adopt a sintered hard alloy (for example, WC-Co (20 wt.%), Young's modulus: 35,000 kgf/mm2) as the base stock for the work rolls 2a, 2b of the 2nd stand 2 and to set the thickness of the outer layer part to >=3% of the radius of the roll. A composite roll in which a sleeve made of the sintered hard alloy is fit may be used.

Abstract: PURPOSE:To enable a wire rod to be wound around a wire winding member having a circular outer shape by only rotating said wire winding member while fixing its position and circulating a shuttle which holds one end of said wire rod through a course of a closed loop having a width. CONSTITUTION:After a shuttle 4 passed through the through hole 21 of a wire winding member 2, the shuttle 4 is repeatedly moved in such a way that a wire rod 1 one end of which is held by the shuttle 4 passes through a set of pulleys 71, 72 and, then, passes through the through hole 21 of the winding member 2 again in the same direction. Further, by changing the direction of the end of the shaft of the pulley 71 (72), the wire rod 1 which is put around the pair of pulleys 71, 72 is transferred from the groove 75 of the pulley onto the wire winding member 2, thereby, winding the wire rod 1 around the wire winding member 2.

Title: Magnetic recording and reproducing device
Inventor: HISATOMI SUSUMU
IPC: G11B15/43
Filed: 1990-09-29
Abstract: PURPOSE:To reduce the occurrence of spring resiliency in the direction of interrupting a housing operation by loosening tension of a coil spring by operating a lever at the time of housing a tension arm. CONSTITUTION:A hook 97 of the coil spring 93 is pulled by the lever 65, and the tension arm 73 is given a moment due to the spring tension. Since the lever 65 is loosely fixed to a mode cam 57 by an axis 67, when the cam 57 is rotated in the direction of A, the lever 65 is also rotated as shown in Figures (b) and (c). Then, when the cam 57 is rotated in the direction of A, an arm 83 and an arm 87 are moved toward the mode cam, and a supply side slider 45 is moved along a groove 49 as shown in Figures (b) and (c). After a bottom part 200 of the slider 45 is brought into contact with a head part 202 of the arm 73, the arm 73 is moved until the state of Figure (d) becomes effective. Thus, the occurrence of the spring resiliency in the direction of interrupting the housing operation is suppressed, and the housing operation is smoothly performed.

Title: Oscillation circuit
Inventor: WATANABE FUMIHIRO
IPC: H03K5/13
Filed: 1986-10-31
Abstract: PURPOSE:To improve an output secondary distortion caused by the load capacity of an output part by securing difference between the forward charging time and the reverse charging direction of a capacitor that prescribes an oscillation frequency. CONSTITUTION:Transistors (TR) Q6 and Q7 are driven by the same voltage supplied from a constant voltage source 8. Then the current I1 flowing through the TR Q6 and the current I2 flowing through the TR Q7 have different levels as constant current in response to the ratio between resistances R3 and R4 owing to these two resistance having different resistance values. Thus the duty ratio of the oscillation output having 50% deviation due to the load capacity CL is corrected by 50% in terms of the center level of the oscillation amplitude. Thus, it is possible to reduce an output secondary distortion caused by the capacity CL.

Title: Temperature controller for fixing device
Inventor: AIKAWA YUKIHIRO
IPC: G03G15/20
Filed: 1993-10-19
Abstract: PURPOSE:To prevent faulty fixing from occurring in the initial stage of processing where it is assumed that the temperature of a pressure roller does not get so high by correcting control temperature to be high in the initial stage of processing. CONSTITUTION:Energizing heater for heating the fixing device for a copying machine is on/off controlled by a control part. When the energizing of the heater is started in accordance with the start of copying and 1st off-temperature T2 is attained, warmup control for stopping energizing is performed. After the warmup control, it is shifted to ordinary control in which specified control temperature Tc is an aim. In the initial stage of processing for the ordinary control, the control temperature Tc is corrected to be higher by an initial correction amount D1 (n) so as to prevent the faulty fixing from occurring. The initial correction amount is made lower and lower as the temperature of the pressure roller becomes higher.
