Title: Laser diode drive circuit
Inventor: NAGANO KATSUMI
IPC: H01S5/0683
Filed: 1986-09-19
Abstract: PURPOSE:To realize a high-speed circuit of a relatively simple construction capable of keeping an optical output at a prescribed value with high stability by a method wherein a current amplifier, etc., are provided whose output current, proportional to the difference between a reference current and photovoltaic current, is supplied to a driven laser diode as a forward current. CONSTITUTION:A driving circuit of this design is provided with a photoelectric conversion means PD capable of generating a photovoltaic current Is proportional to an optical output Po of a driven laser diode LD; a reference current source 3 wherein a prescribed reference current Iref is set; and a current amplifier 2, which is supplied with the reference current Iref outputted by the reference current source 3 and with the photovoltaic current Is generated by the photoelectric conversion means PD and supplies an output current Io, proportional to the difference between the reference current Iref and photovoltaic current Is, to the driven laser diode LD as its forward current If. This design keeps the driven laser diode optical output at a constant level. The optical output controlling feedback Ioop is relatively simple in structure, which reduces delay of response. A high-speed behavior is obtained, and the manufacturing cost is reduced.

Title: Stern pipe of small size ship
Inventor: HARADA KAZUHIRO
IPC: B63H23/36
Filed: 1982-12-14
Abstract: PURPOSE:To effectively utilize the inboard space by supporting a propeller shaft within a stern pipe through an elastic member. CONSTITUTION:Since an engine 6 is supported by a rubber mount 21, its vibrations are not conveyed to a hull 2, and a propeller shaft 1 directly connected to the engine 6 is vibrated in resonance with the engine 6. Since the propeller shaft 1 is held by a bearing 7, vibrations are absorbed by an elastic member 8, thereby bias abrasion can be prevented from occurring. In addition, a stuffing box 4 is connected to a stern pipe 3 with a flexible pipe 5, thereby reliable seal can be attained even though the propeller shaft 1 is vibrated. Accordingly, a size X can be set small and the inboard space can be effectively utilized.

Title: Ophthalmic apparatus
Inventor: TAKAI MOTOYA
IPC: A61B3/10
Filed: 1992-07-28
Abstract: PURPOSE:To efficiently measure ophthalmic refractivity without using a sighting device, by a method wherein a measuring light source located within an apparatus main body is used also for sighting. CONSTITUTION:When ophthalmic refractivity is measured, an external target 28 is separated from an eye E to be examined, by a definite distance, and is presented to the eye E through a light-splitting member 22. The adjustment of the distance between the external target 28 and an apparatus main body 11, at this presentation, is done by turning on a light source 12 for measuring and by projecting the image of the emmetropic fundus onto an eyeground Er, by means of an adjusting switch 31. The external target 28 or the apparatus main body 11 is moved or turned in all directions, vetical and horizontal, in order that the image of the emmetropic fundus is matched to the fixation point of the external target 28, at the face of the eyeground Er, i.e., a visual axis A is matched to an optical axis for measurement. In this way, it is made unnecessary for an examining person to remove and mount a sighting device each time a target position for fixation is adjusted, and thus the examining person can be saved the trouble of moving the sighting device.

Title: Vibration and noise reducing device of arm type sewing machine
Inventor: OTA EIICHI
IPC: D05B69/32
Filed: 1992-07-27
Abstract: PURPOSE:To effectively reduce noise and vibration of an arm type sewing machine resulting from resonance of the frame without furnishing any special member. CONSTITUTION:When an arm type electronically controlled lock stitch sewing machine 1 is in operation, the frame 5 in channel form vibrates in the direction that, in particular, the arm part 4 and bed part 2 go apart and approach relatively, resulting from the drive of a thread in the needle rod vertical motion mechanism of the arm part 4, the cloth feeding mechanism of the bed part 2, etc. If the vibratory frequency of the sewing machine becomes equal to the natural frequency of the frame 5 when the sewing speed is changed from the low to high, the frame 5 vibration increases due to the resonance phenomenon and the noises also are increased, when however a solenoid 24 installed on the arm part 4 for driving a pressure bar works as a dynamic damper having a natural frequency approx. the same as that of the frame 5. which should suppress its resonance and reduce the noise and vibration of the same.
