Title: Compatible optical reproducing device
Inventor: HARADA KENTARO
IPC: G11B7/08
Filed: 1987-09-18
Abstract: PURPOSE:To prevent an optical pickup from being brought into contact with a rotational driving mechanism by providing a means which returns the optical pickup to the uninclined state at the time of switching from reproducing of a large-diameter disk to that of a small-diameter disk. CONSTITUTION:If the light-irradiated part of the disk is inclined when the video disk is reproduced, a tilt servo mechanism is operated to incline an optical pickup 13. When the disk is switched to a compact disk to reproduce this disk, a tilt cam 26 is turned and a leading part 25 of a tilt chassis 22 is relatively moved to the center of this turning and the tilt chassis 22 is approximated to the horizontal state. At this time, a switch cam 27 is rotated and a leaf switch 28 is abutted with the peripheral part of a projection, and it is detected that the tilt chassis 22 is returned to the horizontal state, and the optical pickup 13 is moved in the peripheral direction of the disk in this state and is prevented from being brought into contact with a spindle motor or the like.

Title: Manufacture of light source bulb
Inventor: NAKAMURA KOICHI
IPC: H01J61/35
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To dry a paint for a shading film in a short time without foaming the liquid constituent in the paint in relation to the manufacturing method of a light source bulb, composed by forming the shading film on the circumferential surface of a cylindrical glass tube. SOLUTION: In this manufacturing method of a light source bulb, drying of a paint P for a shading film applied to the circumferential surface 18a of a shroud tube 18 is carried out in two processes: a preliminary drying process (b) and a main drying process (c). In the preliminary drying process, the paint P is heated to 220 deg.C at a gentle temperature rate of increase, so that the liquid constituent in the paint P is evaporated. Thereby, the foaming of the liquid constituent in the paint P is prevented in advance, even if the paint P is heated at a somewhat steep temperature rise rate in the successive main drying process. In the main drying process, the paint P is heated and baked at a temperature increase rate which is steeper than that in the preliminary drying process.  Thereby, the heating period as a whole is significantly reduced, as compared with the case of the conventional case where the paint P is continuously heated at a gentler temperature increase rate to an extent which does not cause foaming so as to complete the baking thereof.

Title: Engine control method of hybrid type electric vehicle
Inventor: KAWASHIMA YOSHIHIRO
IPC: B60L50/14
Filed: 1994-09-28
Abstract: PURPOSE: To prevent erroneous operation of an electronic control unit ECU which arises from a voltage drop in an auxiliary battery due to the starter operation when an engine is restarted in a hybrid type electric vehicle. CONSTITUTION: When an engine is started (S106), an engine start flag FEG is 1 (S107). When the engine stops due to any cause, a step S106 where a starter relay is turned on is avoided (S104) because the engine start flag F is 1, and a starter is not operated. When an IG contact of an ignition switch is turned off (S103) from this condition, the engine returns to the initial condition. Here, when the IG contact is turned on again, the engine start flag FEC becomes zero to make a condition in which the engine can be restarted.

Filed: 1990-09-05
Abstract: PURPOSE:To obtain the optical coupler which has small coupling loss and excellent reproducibility by making a split sleeve larger in rigidity on the fixed- ferrule side than on the ferrule side. CONSTITUTION:The fixed ferrule 4a which is fixed to the photosemicondcutor devide 1a and the movable ferrule 10a of an optical fiber with a connector are held coaxially by the split sleeve 5a and then the image formation point 3 of a light beam which is projected from the photosemiconductor 1a through the fixed ferrule 4a is aligned with the position of the core of the optical fiber 9a. In this optical coupling device, the part 16 of the split sleeve 5a on the side of the fixed ferrule 4a is made higher in rigidity than the part 17 on the side of the ferrule 10a. Consequently, unnecessary motion which may cause decentering can be suppressed without spoiling the elasticity of the split sleeve. Consequently, the optical coupler which has small coupling loss and excellent reproducibility is obtained.

Title: Driving circuit of semiconductor light emitting element
Inventor: TAKAHASHI HIDEO
IPC: H01L33/00
Filed: 1986-09-30
Abstract: PURPOSE:To limit an operation region of a transistor and speed up the ON-OFF operation of a semiconductor light emitting element by connecting a series connection between a Schottky barrier diode and a transistor with the semiconductor light emitting element in parallel. CONSTITUTION:A laser diode 1 is connected between a constant current source 18 connected to a current source terminal 4 and earth and then, a plurality of Schottky barrier diodes 2 are connected in parallel between a collector of a transistor 3 to which an emitter is earthed and the constant current source 18. Subsequently, an electric current always flows from the constant current source 18 to the laser side diodes 1, the Schottky barrier diodes 2, and the transistor side 3 separately and changes a base current of the transistor 3. As a result, such a variation of its base current permits electric currents flowing in the Schottky barrier diode 2 and the transistor side 3 as well as the laser diode side 1 to show a fluctuation and perform the On-OFF operation of a light output in the laser diode 1. The drive is so performed at a limited part of an active region of the transistor 3 that the laser diode can be driven at high speed.

Title: Copy magnification fine-adjustment method in digital copying machine
Inventor: SAKURAI TETSUO
IPC: H04N1/04
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To fine-adjust the copy magnification with high accuracy by changing the number of revolutions of a polygon mirror and a write clock interlokingly, so as to fine-adjust only the copying magnification of an original in the subscanning direction. SOLUTION: Since a scanning time per one mirror surface is changed by changing the number of revolutions of a polygon mirror, corresponding to a magnification in the fine-adjustment of the copy magnification to fine-adjust the copy magnification in the subscanning direction, the magnification in the main scanning direction is changed by the same. Then a write drive control means 6 changes the number of revolutions of the polygon motor and a write clock interlockingly. When the resolution is deficient with a single oscillator (PLL) of a write clock generating means, high resolution is obtained through a 2-stage connection of the PLLs in series, and since the number of revolutions is high and the frequency is high, the copy magnification in the main and subscanning directions is fine-adjusted with high accuracy and high resolution in a stable state.
