Title: Multi-channel type digital signal reproducing device
Inventor: KAMINAGA KOZO
IPC: G11B20/12
Filed: 1986-07-11
Abstract: PURPOSE:To avoid centralization of error data and to secure the satisfactory correction of error data by having different combinations of plural tracks between at the times of recording and reproduction. CONSTITUTION:The tracking control is carried out so that rotary heads 6A and 6B scan correctly on a magnetic tape by a servo circuit related to a capstan motor 20. The phase of a reproduction control signal is shifted by a delay circuit 23 and this shift value corresponds to the value that causes a track shift between the times of recording and reproduction. Therefore a set of two tracks which are reproduced at a time like (B1, A2)(B2, A3)... are shifted by a track against the recording mode. Both tracks B1 and A2 are scanned at a time and the error data are produced at an approximately same position as shown by X. If these error data are uncorrectable, the video data on different areas are recorded on the tracks B1 and A2. Thus the error data are satisfactorily corrected by correction circuits 13A and 13B.

Title: Fluorescent lamp unit
Inventor: ITOU HIDENORI
IPC: H01J61/96
Filed: 1981-10-15
Abstract: PURPOSE:To obtain a fluorescent lamp unit that optimizes its mercury vapor pressure and suppresses the degradation of a luminous flux under a low temperature atmosphere not only by dissipating the heat generated by a bulb but also by applying the heat to the tube wall of the fluorescent lamp. CONSTITUTION:A power supply and a fluorescent lamp 1 are connected through a bulb metal cap 4. A bulb 5 acting as a resistance ballast is inserted in either of lead wires that connect the bulb metal cap 4 and the fluorescent lamp 1. A starter 6 connects the non-power supply side terminals of both filaments of the fluorescent lamp 1. In the said fluorescent lamp unit, the air heated by  the heat of the bulb 5 is not contained in a holder 2 but is diffused at an enclosure side through a connecting groove 11. As a result, the temperature rise in the holder 2 can be restrained remarkably as compared with the case where the inner part of the holder is closed tightly. Besides, the heat transferred in the enclosure 7 can warm the outer surface on the tube wall of the fluorescent lamp 1 and restrain the degradation of luminous flux caused by the tube wall temperature fall, i.e. mercury vapor pressure drop.

Title: Torque ripple suppressing method for induction motor
Inventor: KAMIGAICHI YUJI
IPC: H02P27/04
Filed: 1993-07-01
Abstract: PURPOSE:To suppress torque ripple by lowering the field below rated level when the rotational speed is zero and increasing the first output current from a vector operating section along with the frequency of total rotational field including the rotational speed thereby increasing the frequency of torque ripple generated on the motor shaft. CONSTITUTION:When the field phi2 is lowered below a rated value under a state where the rotational speed omegar goes zero, first output current i1q from a first divider 11 receiving a torque input TM increases and the slip frequency omegas of a second divider 13 receiving an output voltage -e2q from the first divider 11 and the field current phi2 (denominator input) increases. Consequently, the frequency omega0 of the total rotary field, obtained by adding the slip frequency omegas and the rotational speed omegar by an adder 5, increases and then fed to a vector operating section 2 thus increasing the frequency of torque ripple generating on the motor shaft. Consequently, the torque ripple disappears before the torque is transmitted to a load from the motor shaft through a transmission system.
