Title: Magnetic disc assembly
Inventor: SANADA YOTARO
IPC: G11B23/00
Filed: 1994-02-22
Abstract: PURPOSE:To easily exchange a defective magnetic disc medium by tightening and securing a clamp ring to a cap through shrink fitting after fixing the cap to a spindle hub. CONSTITUTION:A cylindrical cap 5 having the same outer diameter as that of a spindle hub 3 is clamped and secured to an upper part of the spindle hub 3 by a plurality of screws 6 in a state where a predetermined number of magnetic disc media 1 and spacer rings 2 are alternately layered in the spindle hub 3. Then, a clamp ring 4 is heated and inserted into the cap 5. Finally, the clamp ring 4 is cooled to be held in touch with the cap 5 securely. The magnetic media 1 and spacer rings 2 are fixed to the spindle hub 3 by the clamping force. If the magnetic disc medium 1 is defective, the defective medium 1 can be exchanged by detaching the screws 6 and then detaching the cap 5 and clamp ring 4.

Title: Optical information recording and reproducing device
Inventor: ROKUTAN TAKAO
IPC: G11B7/09
Filed: 1988-02-05
Abstract: PURPOSE:To prevent off-track from being detected erroneously due to a flaw on a recording medium by moving an objective lens and a mirror integrally and detecting a lens position from the output difference of a bi-sected optical sensor for the reflected light of the mirror. CONSTITUTION:The objective lens 9 for beam convergence and the mirror 10 are provided on a holder 11, and the beam light of a light emitting element 12 is reflected on the mirror 10, and made incident on the bi-sected optical sensor 13. When the mirror 10 is moved horizontally, the beam light shifts on the sensor 13, and the output difference is generated between sensor constitution parts 13a and 13b. Therefore, it is possible to detect the position of the mirror 10 by taking the difference, and also to detect the position of the lens 9 operated integrally with the mirror. Thus, by performing the position detection of the lens, not by the reflected light of a track, the erroneous detection of the off-track due to dust or the flaw on the track can be prevented from being generated, and the detection is performed with high reliability.

Title: Constant voltage generating circuit
Inventor: NISHITOBA SHIGEO
IPC: G05F1/00
Filed: 1990-02-01
Abstract: PURPOSE:To improve the accuracy of an output voltage by changing the resistance values of the first and second resisting means for dividing the output voltage. CONSTITUTION:Resistors R201, R202 and R203 are used for correcting a relative ratio between feedback resistors R5 and R6, and diodes D201, D202 and D203 are used for Zener zap trimming. In such a case, since the output voltage is determined according to the relative ratio between the feedback resistors R5 and R6, the value of the output voltage is measured and trimming is exerted upon the diodes D201, D202 and D203 so that the relative ratio between the feedback resistors R5 and R6 can be set at a prescribed value. Thus, correction by the Zener zap trimming of a band gap regulator at a reference voltage source 1 can be made very small and the reference voltage can be suppressed within rated dispersion.

Title: Heating cooking apparatus
Inventor: IKEDA NOBUO
IPC: H05B11/00
Filed: 1988-02-04
Abstract: PURPOSE:To prevent rush current effectively by utilizing non-service time of a resistance heat-emitting member, and connecting in series with a high voltage transformer when a high frequency oscillator is started. CONSTITUTION:When food is placed in a chamber 11 and a door 13 is shut, switches 9, 11 are actuated to cause a control circuit, out of illustration, to turn on a relay 5. A computer in this control circuit closes a relay 7 to the NC side, and current flows to a high voltage transformer via a heater 2 so as to suppress the rush component. After the computer has counted a certain member of power supply frequency, a relay 6 is turned on. This causes shortcircuiting of the heater 2, and normal voltage is impressed on the high voltage transformer. In heater mode, relays 4, 6, 8 are tuned on, while the relay 7 is closed to the NO side. Without addition of a relay to be specially devoted for the purpose, a circuit with high safety is obtained only by the use of 2-contact type relay.

Title: Angular velocity sensor using tuning fork crystal vibrator
Inventor: NAKAMARU KUNIHARU
IPC: G01C19/5607
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To improve detecting sensitivity by flattening a center of a lower end face of a tuning fork groove, thereby suppressing a sensor output (normal output) in the case of no rotation. SOLUTION: A tuning fork type crystal sensor of an angular velocity sensor is formed, for example, by providing driving electrodes 7a, 7b, 8a, 8b for exciting a tuning fork vibration and sensor electrodes 9a, 9b, 10a, 10b for detecting charge generated by Coriolis force at a tuning fork-like crystal 6 formed by rotting a Z-cut plate having a main surface crossing perpendicularly to the Z-axis of a crystal axis at about 0 to 5 degrees at the X-axis as a rotating axis, and forming a lower end face of a tuning fork groove 3 in a flat surface by a diamond wheel. With this constitution, even when T/W and W/T in which values of widths T and thicknesses T of arms 4, 5 are approached are 0.6 or more, vertical vibration in vibrating the tuning fork is prevented to suppress normal output, thereby improving a detecting accuracy of the crystal sensor.  Even when only the center of the lower end face of the groove is flattened, similar effect can be expected.

Title: High luminance part compressing method for object image
Inventor: OZEKI TORU
IPC: G06T5/00
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To generate an image applying a natural impression without any sense of incompatibility when the compressing processing of a super high luminance part in an object image is performed. SOLUTION: A highlight area is set in a prescribed size with a regular reflection position P0 as a center on the object at the position to regularly reflected irradiation light toward the direction of a line of sight. Edge lightness is found as the lightness of edge parts P1, and P2 in the highlight area. When the edge lightness is higher than an upper limit lightness value, the color of the object is controlled. At this time, color control width is determined so that the lightness in the highlight area can be equal with the upper limit lightness value and the lightness outside the highlight area can be lower than the upper limit lightness value.  When the saturation of the highlight edge parts P1 and P2 is low, the said color control width is corrected and reduced and the sense of incompatibility is prevented from being generated by the excessive state of saturation with color control.
