Title: Apparatus for controlling irradiation direction of lighting tool
Inventor: IZAWA MAKOTO
IPC: B60Q1/115
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To accurately and speedily determine an initial position of a stepping motor in an irradiation control device for a lighting tool using the stepping motor. SOLUTION: In an irradiation direction control device 1, a driver 4 for directing an irradiation direction of a lighting tool 5 toward a desired direction comprises a stepping motor 6 and a drive mechanism 7 driven by the motor 6. A rotating angle range of the stepping motor 6 depends upon a movable range of the drive mechanism 7. When an instructing device 2 sends, to a controller 3, a command signal for determining an initial position of the driver 4 after the operation of the control device 1, the controller 3 sends, to the stepping motor 6, a control signal inclusive of an angular command beyond the rotating angle range corresponding to the movable range of the drive mechanism 7 and a speed command for rotating the stepping motor 6 at a first rotating speed N1 at that time.  Thereafter, the controller 3 sends, to the stepping motor 6, a control signal for rotating the stepping motor 6 by the predetermined number of steps at a second rotating speed N2 (lower than the first rotating speed N1), thereby reducing a vibration width generated when the drive mechanism 7 reaches a limit position within the movable range.

Title: Pickup driving device
Inventor: TAKAHASHI HIROYUKI
IPC: G11B21/10
Filed: 1989-05-29
Abstract: PURPOSE:To improve the quick-responsiveness or lead-in force of a tracking servo and to prevent off-track by setting the gain of a tracking servo loop based on the moving speed of a carriage. CONSTITUTION:By setting a reference voltage Vref slightly lower an activating voltage with which a carriage motor 7 starts normal operation, a comparator 10 generates a trigger signal (c) almost just before the operation timing of the carriage motor 7. Almost during the operation of the carriage motor 7, namely, during the move of the carriage, by a monostable multi-output (d) to be generated in correspondence to this trigger signal, the gain of an equalizer amplifier 3a rises up to a value, which is set in advance, by a gain control circuit 12. Thus, while the carriage is moved, the sensitivity of the tracking servo loop is enlarged and the quick-responsiveness or lead-in ability to disturbance is improved. Then, the jump of a track is prevented.

Title: Pressure measuring diaphragm
Inventor: TAMAI MITSURU
IPC: G01L7/08
Filed: 1978-11-02
Abstract: PURPOSE: To increase both the linearity and the restoring properties between the actual pressure and the measurement result by forming the Z-shaped thin-depth area between the support part at the circumference and the center pressure measurement part via the concentric circular channels of different diameters.  
     CONSTITUTION: Circular channel 21 enclosing pressure measurement part 19 is provided on surface 20 at one side and at the border between support part 17 at the circumference of disk-shaped pressure measuring diaphragm 16 and the center pressure measurement part 19. At the same time, another circular channel 23 concentric to channel 21 with a little smaller outer diameter than the inner diameter of channel 21 is provided on the other surface 22. As a result, the Z-shaped thin- depth part 24 is formed between part 17 and part 19 via channels 21 and 23. Part 24 absorbs the tension and the curve toward the center of part 17 caused by the bending of part 19 when the pressure is applied, which results in virtually no malformation of part 17 and a small amount of the energy consumption. Thus the linearity and the restoring properties can be increased between the actual pressure and the measurement result.

Title: Boom controller of boom type working vehicle
Inventor: SASAKI HIDEYUKI
IPC: B66C23/88
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To eliminate troublesome boom operation without any special detecting means by stopping the boom operation with the first critical value as a reference when the boom is in the range of the turning angle of the forward performance region and not turned, or with the second critical value as a reference when the boom is not in the range of the turning angle and is turned. SOLUTION: When a boom is not located in the range of the turning angle of the forward performance region, or when the boom is turned, the elevation stop angle of the lowering operation of an expandable boom is calculated from the real load to be calculated with the critical working radius in the all-round performance region. When the turning of the boom is stopped, the elevation stop angle of the lowering operation of the expandable boom is calculated from the critical working radius in the forward performance region and the real load. The differential angle between the detected elevation angle and the calculated elevation stop angle is calculated to obtain the pressure reduction command value.  The expansion speed of an elevation cylinder is reduced according to the reduction command value, and the expandable boom is smoothly stopped when the expandable boom reaches the critical position in the forward performance region or in the all-round performance region.
