Title: Control method for floppy disk device
Inventor: KOYAMA TAKUO
IPC: G11B19/10
Filed: 1991-05-02
Abstract: PURPOSE:To provide a control method for a floppy disk device in which the damage of a floppy disk is completely restrained, whose life is prolonged and which is made reliable. CONSTITUTION:When the power source for the floppy disk device is turned on, a reset signal (h) for inhibiting the rotation of a motor for driving the floppy disk device is supplied from a computer side to the reset priority RS flip-flop provided with clean input of the floppy disk device. Since the motor for driving the floppy disk device does not start to rotate only by turning on the power source for the floppy disk device, rotation is not continued in a state where the information writing and reading head of the floppy disk device is positioned on the same track, and the life of the floppy disk is prolonged.

Title: Viterbi decoder
Inventor: HAMADA TOSHIMASA
IPC: H03M13/23
Filed: 1990-05-18
Abstract: PURPOSE:To simplify circuit constitution and to accelerate an arithmetic operation by making the data output line of a memory correspondent to a new pathmetric and path selection information representing the output line of an arithmetic unit and storing the result of the arithmetic operation to an address corresponding to an input signal. CONSTITUTION:When a branch metric 8A, a control signal 9 and a preceding pathmetric 10 in a viterbi decoder are decided, since the state of an address input line 19 of read-only memory 18 of the arithmetic unit 2A is decided, the result of arithmetic operation stored in advance is outputted as it is to a data output line 20 as the content of a relevant address. Thus, a new pathmetric 11 and path selection information 12 are obtained without implementing the arithmetic operation at every signal input. Since it is not required to make arithmetic operation at every signal input, the time for the arithmetic operation is omitted and high speed processing is attained and wiring interconnecting arithmetic circuits is not required and the circuit is suitably simplified.

Then, the taking-out device M is moved into the press, and after receiving the tire T and discharging it to the exterior of the press, the raw tire GT is gripped by the feeding-in device N for the raw tire, and is brought into the press. Thereafter, the tread segment K2 is opened so that the inside envelope thereof attains a diameter larger than the outside diameter of the raw tire, the feeding-in device N is moved upward, and a bead part of the raw tire is seated on a bead ring of the upper metallic mold.

Title: Inner lead top end structure of lead frame and forming thereof
Inventor: ARAGAKI TAKESHI
IPC: H01L21/60
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To improve energy efficiency for bonding a thin metal wire to the top end of the inner lead of a lead frame having wiring terminals for electronic devices having resin-molded chips by cutting the top end of the inner lead to form an inclined face. SOLUTION: A wiring pattern of a lead frame is formed by the etching and press cutting steps. The inner lead 3 connected to a chip mount is formed by etching and press cutting steps and cut off from the chip mount by a press cutting step. As the result, a bur extending vertically down appears at the top end of the inner lead 3. The bur is pressed until plastically deformed to form an inclined face 10, as the bar is pressed to the taper face. Thus the inclined face 10 is formed at the top end of the inner lead 3.

Title: Diaphragm pump
Inventor: HARA MASUMI
IPC: F04B43/067
Filed: 1983-07-14
Abstract: PURPOSE:To control a negative pressure produced in a cylinder, by installing an on-off valve in a communicating hole through which a working oil chamber is communicated with a tank. CONSTITUTION:During lowering stroke motion of a piston 4 right after working oil in a working oil chamber 8 is discharged during raising stroke motion of the piston 4, the interior of the working oil chamber 8 is brought into a negative pressure resulting from volume expansion at the interior of a cylinder 3. A difference in a pressure between the interior of the working oil chamber and the interior of a tank 2 which is held at an approximately atmospheric pressure causes opening of an on-off valve 40 against the resilient force of a spring 38, and working oil in the tank 2 is supplied in the cylinder 3 through a communicating hole 33, resulting in prevention of the generation of a negative pressure. This prevents corrosion of the inner surface of a cylinder and eliminates a wasteful power consequent on negative pressure operation.

Title: Varifocal lens
Inventor: UENO AKIRA
IPC: G02B7/08
Filed: 1990-05-18
Abstract: PURPOSE:To drive the lens having preference to speed when switching a focal distance or having preference to accuracy in the case of focusing by automatically changing and setting a voltage to be supplied from a driving voltage supplying means to a motor driving means based on an operational mode select signal from a selection control means. CONSTITUTION:More than one movable lens group, namely, a front group frame 10 and a rear group frame 20 are displaced by a lead screw driving system equipped with a pair of deceleration gear trains. Then, two kinds of focal distances are realized at least, and the switching operation of the focal distances and the focaling operations in the respective focal distances are executed by the common motor driving means. In this case, when switching the focal distance, the speed of driving a movable lens group is accelerated by increasing the voltage to be fed to the motor driving means and in the case of focusing in each focal distance, the speed for driving the movable lens group is decelerated by decreasing the voltage to be fed to the motor driving means. Thus, when switching the focal distance, control having preference to the speed is enabled and in the case of focusing in each focal distance, control having preference to the accuracy is enabled.

Title: Belt drive type continuously variable transmission
Inventor: JITSUMATSU HIROAKI
IPC: F16H61/00
Filed: 1988-05-26
Abstract: PURPOSE:To make it possible to make a hydraulic pump small in capacity by making the coefficient of friction great in the range of a low change gear ratio, and small in the range of a high change gear ratio wherein the coefficient of friction represents that of an endless belt at the holding surfaces of at least one of a primary or a secondary pulley. CONSTITUTION:The coefficient of friction of an endless belt at the holding surfaces 44a and 44b of at least one of a primary pulley 32 or a secondary pulley 34, r example, the secondary pulley 34 is made great in a coefficient of friction in the range of a low change gear ratio, great belt holding force can thereby be secured even if hydraulic pressure is low. This permits hydraulic pressure for pressing at the time of a low change gear ratio to be set low so that a hydraulic pump of a small capacity can thereby be used. In addition, the coefficient of friction at the belt holding surfaces 44a and 44b is made small in the range of a high change gear ratio, an oil film will never therefore be broken at the belt holding surfaces 44a and 44b even if hydraulic pressure for pressing is set high in this range. Which situation prevents the occurrence of nonconformity such as solid contact between a belt and the pulleys and the like, thereby improving durability. Hydraulic pressure for pressing can also be set high in the range of a high change gear ratio so that the change gear ratio is improved in stability.
