Title: Opticak disk and apparatus for recording optical disk matrix
Inventor: UEMURA YUTAKA
IPC: G11B7/24085
Filed: 1995-03-15
Abstract: PURPOSE: To obtain an optical disk which does not accompany a decrease of C/N when recording identification data or the like by a wobble track every other sector if a count of sectors in one track is an odd number. CONSTITUTION: Physical phases of wobbles of wobble tracks 2, 3 on an optical disk are arranged to be inverted at the side of an inner periphery (n-1) and at the side of an outer periphery (n+1). A positional relation between sub beam spots 5, 6 and adjacent wobble tracks 2, 3 is always symmetric, and therefore crosstalks from adjacent right and left tracks are offset in a tracking error signal as a differential output. A noise level is accordingly lowered, and a C/N of a signal of wobble frequency components is improved, whereby data such as an identification signal or the like are never improperly detected.

Title: Manufacture of sic heater
Inventor: KITAHAMA HIROAKI
IPC: H05B3/14
Filed: 1995-02-08
Abstract: PURPOSE: To provide a safe and reliable SiC heater that can stand a long time of service by integrating a heat generating section formed out of a plurality of SiC sheets, with a non-heat generating section formed out of an odd number of alternately stacked SiC and NbB2 sheets. CONSTITUTION: An assistant and a binder are added to SiC powder, thereby forming an SiC sheet 1. On the other hand, a sheet 2 is formed, mainly composed of the boride, silicide, carbide or the like of metal such as Zr, W and Nb. Then, the odd number of the sheet 1, or five sheets 1, for example, are stacked to form a heat generating section. On the other hand, the sheet 1 and the sheet 2 such as an NbB2 sheet are alternately stacked on top of each other to form a non-heat generating section. The stacked body so made is molded under pressure and cut into a U-shaped form. This compact is sintered in N2 at a temperature approximately between 1,900 and 1,950 deg.C, thereby preparing a heater body element. Furthermore, a lead wire 5 is brazed to both ends of the element via a joint section 6, thereby providing an SiC heater body 7.

Title: Motor controller
Inventor: OKUYAMA YOSHIHIRO
IPC: H02P29/40
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To realize the stable motor control by detecting the rotational angle of a motor, estimating the motor current, based on the signal of the rotational angle and the signal of the velocity command, and providing a second feedback loop to feedback to the motor applied voltage, based thereon to estimate the motor current without using a current sensor. SOLUTION: The angular velocity (ω) of a motor is converted into the rotational angle θ by an integration element 18 and detected. The detected value is fed to a motor current estimation part 20 and a differential element 19, and again converted into the angular velocity (ω). A velocity-torque command conversion part 21 estimates the torque (τ) based on the angular velocity ω, and the motor current estimation part 20 estimates the current (i) based on the torque τand the rotational angle θ. The current (i) is again converted into the voltage (v) by a proportional element 17, and feedback is made so as to be subtracted from the output of the proportional element 12. The stable motor control can be realized by making feedback to the motor applied voltage, based on the estimated motor current.

Filed: 1981-04-13
Abstract: PURPOSE:To always flow the prescribed current to a load which is connected to a collector even if hFE is varied in the manufacture by employing a diffused resistor having a correlation with the hFE. CONSTITUTION:A P type base 8a and a strip resistance layer 8b are simultaneously formed in an N type Si 7, and an N<+> type layer 9b and an N<+> type collector connection layer 9c are simultaneously formed except both ends of an N<+> type emitter 9a and a strip P type resistance layer 8b. A hole 11 is opened at the surface insulating film, and electrodes are attached thereto. Since the layers 8a-8b, 9a-9b are simultaneously diffused, a simply increasing correlation is produced between the hFE of a transistor 1 and the diffused resistors 2, 3. Accordingly, R/hFE does not vary, and the collector current IC is constant irrespective of the value of the hFE.
