Title: Floppy disk device
Inventor: INAGUCHI TETSUYA
IPC: G11B21/02
Filed: 1994-03-10
Abstract: PURPOSE:To make a floppy disk device smaller and thinner without deteriorating the rigidity of a carriage pin holding part and to improve the workability by forming the pin holding part of a metallic material and force-feeding the pin into a narrow groove-shaped receiving part provided on this pin holding part. CONSTITUTION:The rigidity required for the floppy disk device is sufficiently maintained since the carriage pin holding part 15 is made of metal even though it is made smaller and thinner. Then, the degree of freedom for arranging the carriage pin holding part 15 in the floppy disk device is increased, e.g. the holding part 15 can be arranged at the side surface of a recording medium M, thereby the whole floppy disk device is made smaller and thinner. Also, the pin 18 is fixed by force-feeding the metallic carriage pin holding part 15 into the receiving part, therefore, it is surely fixed to the carriage pin holding part by only the force-feeding work of the pin 18. Thus, complicated works such as the adhering work after the force feeding, the pin handling work in the integrated molding of the pin by a die, and the like, as in the conventional manner, are made unnecessary.

Title: Manufacture of stator for step motor of timepiece
Inventor: OOTAWA SHIYUUJI
IPC: H02K37/16
Filed: 1981-03-19
Abstract: PURPOSE:To lower the saturated magnetic flux of the minimum sectional area part of a stator for a step motor of a timepiece and to realize lower power consumption at the step motor by machining the part to which the rotor of the stator is inserted in a circular hole after magnetically annealing the portion in the noncircular hole state and imparting a machining strain to the part. CONSTITUTION:The part of a stator 1 at which a rotor is inserted is magnetically annealed in the concircular hole state. Then, a circular hole machining pin 4 and stator guide pines 5, 6 are stood on a jig stand 2, and the stator 1 thus magnetically annealed is placed with the pin as a guide. When a pressing pin 3 is moved, the stator 1 is flared by the shape of the pin 4 and becomes a circular shape. At this time the plastically deformed part of the stator 1 has a small sectional area, a machining strain remains at the part, and the saturated magnetic flux density is extremely reduced.

Title: Folding electronic equipment
Inventor: KUBO TOMOKO
IPC: H01H9/02
Filed: 1992-01-30
Abstract: PURPOSE:To prevent the occurrence of malfunctions of a folding electronic equipment by stopping the function of an input means when a folding state is cancelled. CONSTITUTION:The side face of a stage part 57 of a 1st carrying member 44 is provided with a hook 58, and the side end face of a 2nd carrying member 46 is provided with a projection 56. When a folding state is cancelled between both members 44 and 46, the projection 56 does not push the hook 58 any more and therefore the hook 58 protrudes forward. Under such conditions, the button provided at the outside of the member 46 becomes disabled or stops its function by the function of an electronic circuit which works with the forward movement of the hook 58. Therefore the operation corresponding to each outside button is never carried out even if a user touches the button by mistake. Thus a folding electronic equipment has no malfunction.

Abstract: PROBLEM TO BE SOLVED: To easily change a transmitting torque value by enabling the driving side friction member of a driving side rotor and the driven side friction member of a driven side rotor to be pressure connected to each other, and enabling the pressure connection territories of the mutual friction members to be changed. SOLUTION: A driven side rotor 41 is provided with a driven side friction plate 43 as a driven side friction member therein. A driving side rotor 40 is fitted with a driving side friction plate 45 as a disc-like driving side friction member movably in the axial direction on the cylindrical part 40c.

Under the condition of pressure connecting the large diameter friction face 45c to the driven side friction plate 43, friction force becomes large, and under the condition of pressure connecting the small diameter friction face 45d to it, friction force becomes small.  Hereby, the torque value transmitted to the driven side rotor 41 can be changed.

Abstract: PURPOSE:To improve the accuracy and the stability of tracking control by using the difference of the multiplication value of the output of respective two pieces of detectors being in one side and the other side of a track center line as an error signal in a quadripartite photodetector. CONSTITUTION:The quadripartite photodetector 7 is divided into four pieces of photodetectors 7a-7d by dividing lines 7Y, 7X intersecting orthogonally with each other. The outputs of the detectors 7a, 7d and 7b, 7c are multiplied with respective AC components by multipliers 8A, 8B respectively. The output of the multipliers 8A, 8B are applied to a differential amplifier 9 and a difference signal E1 is taken out as a tracking error signal. By the system, a signal component in a land part containing no information of a track deviation and being affected largely by the inclination of a disk is not contained in the error signal E1 and further the error signal in pit part is detected remarkably.

Title: Data recording and reproducing device
Inventor: YOSHIMOTO KAZUO
IPC: G11B20/10
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To efficiently record and reproduce an input/output data at a variable data rate and to simply control recording and reproducing operation in this case. SOLUTION: The recording rate of a recording and reproducing part 7 is higher than an input data rate. Input data is once written in a memory 5, and the data read out of the memory 5 is recorded on a tape by the recording and reproducing part. The inflow of data to the memory 5 is started, and when the data amt. stored therein is increased to reach an upper threshold High, a recording commencement trigger is given to the recording and reproducing part. The actual recording is commenced to be delayed by a prescribed time from this trigger, and the data in the memory is decreased. Then, at the time of reaching a lower threshold Low, a stop command is given to stop recording operation. When the data amt. in the memory is increased again to reach the upper threshold High, the recording commencement trigger is generated to commence the actual recording.  This recording and stopping operation is repeated until the data in the memory becomes vacant.

Filed: 1985-03-04
Abstract: PURPOSE:To improve mounting efficiency in a module and the mounting efficiency of a printed wiring board by forming a connecting terminal leading out signals even to a section different from a signal leading-out terminal section. CONSTITUTION:Connecting terminals 14, 16 are fitted to sections, to which signal leading-out terminals 3 are mounted, in a ceramic module, and both ceramic modules are connected by conductors such as flat cables on surfaces except surfaces, to which the signal leading-out terminals 3 are fitted, in two ceramic modules. Consequently, electronic parts, which cannot be loaded due to the shortage of the number of the signal leading-out terminals, are incorporated, thus obtaining the ceramic module having high mounting density. The ceramic module and another ceramic module need not be signal-connected on the printed wiring board side to which the ceramic modules are set up. Accordingly, the mounting efficiency of the printed wiring board side can be enhanced.
