Title: Recording and/or reproducing device
Inventor: TANAKA MASATERU
IPC: G11B15/665
Filed: 1991-04-13
Abstract: PURPOSE:To reduce the wear and to prevent a load applied to a ring rotation from increasing by securely contacting a ring positioning leaf spring with the rotating body pressed by the spring when a recording tape is guided to a tape running path by a loading ring. CONSTITUTION:When a loading ring 6 is rotated to pull out a recording tape 104 housed in a tape cassette 101 and to guide the tape to the tape running path, the end part of a positioning leaf spring securely comes contact with a rotating body 24. At this time, since the rotating body 24 runs onto a flat spring 26 while rotating, the frictional force between the rotating body 24 and the flat spring 26 is small. Then the ring 6 is pressed and supported by the flange part on the lower part of a ring guide body 21 whose movement in an axial direction is restricted by the elastic force of the leaf spring 26. Thus, occurrence of the wear of the leaf spring and rotating body can be suppressed and the load the ring rotation can be prevented from increasing.

Title: Sensorless-brushless dc motor driving circuit
Inventor: SEKI KUNIO
IPC: H02P6/18
Filed: 1991-04-12
Abstract: PURPOSE:To minimize a back motion to be generated at the time of starting by transiting a synchronous operation frequency from a frequency higher than a self-starting frequency of a sensorless-.brushless DC motor to a lower frequency when the motor is started. CONSTITUTION:When a motor is started, an oscillation frequency, i.e., an exciting frequency of a VCO 7 is transited to a lower value. As the frequency is lowered, a torque tending to drive the motor is increased. If the torque is increased to a predetermined value or more due to a decrease in the exciting frequency, the motor starts rotating. That is, when the oscillating frequency of the VCO 7 is lowered to a certain frequency (<fs), the motor is self-started (point B). Thus, the motor is always started at a limit frequency (fs) capable of generating necessary minimum limit torque to self-start. Thus, a back motion to be generated at the time of starting the motor can be minimized.

Title: Method for rolling taper plate
Inventor: YOSHII MAKOTO
IPC: B21B37/00
Filed: 1995-05-02
Abstract: PURPOSE: To stably manufacture a taper plate good in dimensional accuracy by preliminarily setting sheet crown in the longitudinal direction of a material to be rolled to the bending force which is coincident with the target sheet crown and dynamically controlling the bending force of a mill during rolling according to the bending force. CONSTITUTION: Since rolling load is increased on the tip side of the plate where rolling reduction becomes larger in a taper imparting pass, sheet crown is increased in the case of comparing to the rear end side. Thus, by making the bending force max. on the tip side of the plate and the bending force min. on the rear end side, sheet crown is calculated. The calculated sheet crowns Crn T, Crn B at the tip and rear end in the final pass are compared with the target sheet crown Crn * and, when difference falls within the allowable value α, rolling is executed according to these pass schedule and bending force.  When the difference departs from the allowable value, Crn T-Crn *<0 and Crn B-Crn *>0, the bending force is changed, the optimum bending force is determined by convergent calculation so that the final sheet crowns Crn T/Crn B fall within the allowable value and rolling is executed.

IPC: G02B6/00
Filed: 1993-05-11
Abstract: PURPOSE:To obtain a liquid crystal display device high in visibility both at the time of turning on and off of an illumination device by providing the illumination device with light transmissivity and illuminating function in a single direction. CONSTITUTION:The illumination device 1 is arranged on the back side of a liquid crystal panel 2 and a reflector 3 is arranged on the back side of the panel 2. The illumination device 1 is provided with such function as projecting a light beam on the reflector 3 side and transmitting the light beam reflected on the reflector 3 almost without being dispersed. That means, when there is sufficient external light, the illumination device 1 is used in off-state, and in such a case, the illumination device 1 works as a simple transparent plate without deteriorating visibility nor affecting display quality. When the illumination device 1 is used in on-state at a dark place with insufficient external light, the panel 2 is illuminated with indirect light by the reflector 3 by the illumination device 1 and the light reflected on the reflector 3 is transmitted as it is because the illumination device 1 functions as the simple transparent plate in the same way as it is turned off. Therefore, the high visibility is held.

Title: Magnetic head holding device
Inventor: OKAMURA KAZUHIKO
IPC: G11B17/32
Filed: 1986-05-13
Abstract: PURPOSE:To reduce the contacting force of a magnetic head and to prolong the service life of the head by fixing end parts of leaf springs to a carrier one over the other and energizing a head arm and a head base by a head pressure spring in mutually approaching directions. CONSTITUTION:The head arm 5 and head base 7 are energized by the head pressure spring 15 in the mutually approaching directions, so when a magnetic disk 1 is curved, the head arm 5 and head base 7 inflect the leaf springs 8 and 9 and are displaced while maintaining the parallel state. At this time, the leaf springs 8 and 9 are superposed and the center 17 of magnetic heads 4 and 6 moves about a part 16 clamped by the carrier 2 and a spring support plate 10 as a fulcrum. Thus, the head arm 5 and head base 7 are displaced according to the curvature of the magnetic disk 1, so the magnetic heads 4 and 6 are brought into contact with the surfaces of the magnetic disk 1 perpen dicularly. Thus, the pressure of a head pressure spring 15 is reduced to reduce a shock at the time of head loading, thereby prolonging the service life of the magnetic heads 4 and 6.
