Title: Stabilization of oscillation frequency interval of plural laser apparatus
Inventor: SHIBUYA MAKOTO
IPC: H04B10/572
Filed: 1988-01-26
Abstract: PURPOSE:To stabilize the interval between oscillating frequencies of a plurality of laser apparatuses, by dividing the output light of each laser apparatus into two parts, synthesizing one of the divided lights, inputting the light into one optical resonator, dividing the light again, synthesizing the light with the other divided laser light, and stabilizing the oscillating frequency of each laser device into one resonant frequency of the optical resonator. CONSTITUTION:Each of the output lights of laser apparatus 1-3 is divided into two parts in fiber couplers 4-6. One divided light is synthesized in an optical synthesizer 7. The light passes through an optical resonator 8 and an optical frequency shifter 9. Then the frequency of the light is converted. The transmitted light is divided into three in an optical frequency divider 10. The lights are synthesized with the other divided laser lights in optical fiber couplers 11-13. The lights are made to pass through band pass filters 17-19 of 90-110MHz through optical detectors 14-16. The beat components are taken out and detected in detectors 20-22. Since the outputs are proportional to the intensities of the transmitting light in the resonator 8, the maximum value is controlled with said signal as a control signal. The oscillating frequency of the laser apparatus 1 can be stabilized into the central frequency of the resonant peak of the resonator 8. The frequencies of the apparatuses 2 and 3 can be stabilized at the central frequencies of the other resonant peaks.

Abstract: PURPOSE:To make a movable block small-sized and light-weight, and reduce generation of particles as far as possible, by applying a constitution wherein the movable block is provided with no adjusting mechanism for the vertical direction, and a guide member for the movable block is instead moved up and down. CONSTITUTION:Link members 26 constitute a link mechanism corresponding to the respective guide members 22 at three positions, namely both end parts and a center part of a guide member 22, in a manner of the so-called three-point supporting. Further the link members are arranged on a horizontal substrate 24 so as to freely rotate, and, via common driving links 27 connected to the lower end parts, are connected to an actuator 28 arranged in a load station so as to be driven. By driving the actuator 28, each link member 26 is vibrated at the same time via the link 27, and the guide members 22 move up and down along the vertical direction Z for the fixed frames 23 and 24 of the load station, while the guide members 22 keep a horizontal state. Consequently, as for a boat supporting arm 20, its position adjustment in the vertical direction is also performed via the guide members 22.

Title: Lens drive device
Inventor: KOBAYASHI KOICHI
IPC: G02B7/09
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To shorten the focusing time in a lens drive device where a stepping motor is employed as a drive source and which has many lens setting steps. SOLUTION: The rotation of the stepping motor 3 is transmitted to a lens drive means 2 through a coupling means 4 and a photographing lens is driven to a focusing position. At the time of starting the motor 3, a start control means 7a drives the motor with pulses in a self-start region and then an acceleration control means 7b increases the pulse frequency from the self-start region to a through-region. After reaching the through-region, a constant-speed control means 7c drives the motor in terms of constant speed. When the lens reaches the vicinity of a target focusing position, a deceleration control means 7d decelerates the pulse frequency from the through-region to the self-start region and a stop control means 7e stops the motor at the time of attaining the target focusing position.  At the time of starting and at the time of stooping, the motor is driven in the self-drive region but the drive of the lens is mostly performed in the through-region, so that the time required for focusing is shortened.

Abstract: PURPOSE:To suppress a washing water from splashing after having run against a human body by spouting a main stream for washing, which is directed to the local part concerned from the termination of a washing water flowpath. and an aux. stream which makes covering at least in the form of an arc of circle on the streamline of the main stream from the termination of the washing water flowpath, CONSTITUTION:The first flowpath 5b has a spout hole 5b-1 which is opened in the center of a spout head 5a, wherein the angle of the axis of the spout hole 5b-1 to a horizontal plane is made between 60-70deg. The second flowpath 5C is equipped with a greater flowpath area than the first 5b and has a slit 5C-1 in the form of an arc of circle positioned above the spout hole 5b-1. A stream of a washing water (main stream) from the spout hole 5b-1 becomes a small diameter line and draws a streamline directed straight to the local part concerned P. while another stream of washing water (aux. stream) discharged from the slit 5C-1 draws a streamline curving downward being influenced by the gravitation force because of bearing a weak energy and being a discharge water in the form of water film having a circular arc section. The main stream runs against the local part P to make splash, and the aux. stream becomes a screen to prevent splashing.

IPC: G03B27/40
Filed: 1988-01-28
Abstract: PURPOSE:To securely arrange a lens on an optical axis of printing by stopping driving a turret before an opening and the lens reach the optical axis, and then rotating the turret by its inertial and pressing a projection against the outer periphery of the turret. CONSTITUTION:In printing operation, a solenoid 78 is excited to extract a projection part 72A from a recessed part 74A, and a motor 41 is driven to rotate the turret 38 clockwise, so that lenses 24A-24F are selected and arranged on the optical axis P. Namely, when the turret 38 is rotated and a stop pin 64A corresponding to the selected lens is detected by a stop sensor 68, the driving of the motor 41 is stopped a specific time later and the turret 38 rotates by its inertial force. In this state, when the stop pin 64 is detected by the stop sensor 68, the excitation of the solenoid 78 is eliminated and an arm 72 enters the recessed part 74B with the energizing force of a leaf spring 76, so that the turret 38 stops rotating immediately. Consequently, the selected lens among the lenses 24A-24F is accurately arranged on the optical axis.
