Title: Optical homing device
Inventor: KATOU SHIROU
IPC: G01S17/66
Filed: 1981-07-20
Abstract: PURPOSE:To elevate and simplify a tracking performance, by constituting an optical homing device of an optical system having spherical aberration, a two- dimensional image sensor and a picture signal processor, and positively utilizing the spherical aberration. CONSTITUTION:This device is constituted of an optical system 1 having different focal distances on the concentric circle from space areas S1-S3, a two-dimensional CCD sensor 2 and a picture signal processor 3. In this optical system, the focal distances are varied as f1-f3 in accordance with a distance variation from the center, and the sensor 2 is placed in a position of f3. Accordingly, when an object is in infinity, the object and the background are at an equal distance, and an area of S3 condenses. When the object approaches, the condensing part is varied as S2 S1. On the other hand, the background is condensed by the S3 part, therefore, when the object has approached, the spherical aberration has an effect of one kind of space frequency adaptive filter. Therefore, the tracking property can be elevated by utilizing the spherical aberration and equalizing a performance variation of a detector due to a variation of a distance reaching the object.

Title: No-contact ignition device for internal-combustion engine
Inventor: CHIGUSA YUUJI
IPC: F02P5/155
Filed: 1983-06-22
Abstract: PURPOSE:To delay the angle of ignition timing by a simple structure at the time of overrunning by providing a sensor coil to generate AC output signals at fixed intervals in the turn of negative and positive. CONSTITUTION:A sensor coil 9 generates one-cycle signals of different polarities in the turn of negative and positive. When a control condenser 11 is charged into an illustrated polarity by the first negative half-wave of this sensor signal, a negative bias is given to an A-point. When the number of revolutions comes to an overrunning value, the electric potential at the A-point is rapidly reduced. Consequently, the amount of delay angle is increased as the number of revolutions is increased. This construction permits to delay the angle of ignition timing by a simple structure at the time of overrunning.

Title: Limit switch
Inventor: KISHIDA MASARU
IPC: H01H21/28
Filed: 1989-05-02
Abstract: PURPOSE:To thin a limit switch so as to reduce the space required for its attachment and enable the use of plural switches being connected together by forming a control lever using a pair of front and rear lever pieces both arranged within the thickness of a switch case. CONSTITUTION:A control lever 9 comprises a pair of front and rear lever pieces 9A, 9B connected to respective ends of a rotary shaft 8 within the thickness of a switch case 1, and a roller 10 is positioned at roughly the center of the thickness of the case 1 and is axially supported between the end portions of the lever pieces 9A, 9B. The size of the whole switch in the direction of its thickness is thereby reduced and it is made easier to reduce the space required for attachment of the lever. Because the control lever 9 does not stick out of that outer face of the switch case 1 which is along the direction of thickness, such a service condition is also possible that plural switches are attached while being connected to each other. Thus the space required for attachment of the lever is reduced and a limit switch capable of being attached in such a way that a plurality of it are connected together is thus obtained.

Title: Semiconductor laser stimulating solid-state laser
Inventor: OKAZAKI YOJI
IPC: H01S3/094
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor laser stimulating solid-state laser which is capable of preventing its oscillation laser beam from being deformed in cross section by a method wherein an Nd:YVO4 crystal used as the solid-state laser is prescribed in Nd content. SOLUTION: A semiconductor laser stimulating solid-state laser is of c-axis absorption and c-axis oscillation type, where a laser crystal such as an Nd:YVO4 crystal of small thermal conductivity coefficient is used, a thermal lens effect is generated when an exciting power is increased, and an oscillation laser beam is deformed in cross section. Then, when Nd added to an Nd:YVO4 crystal is reduced to 0.7 at.% in content, the absorption coefficient of the laser crystal is reduced to below 28 cm-1, so that a thermal lens effect is restrained, and a laser beam emitted from the solidstate laser crystal is prevented from being deformed in cross section.  A thermal lens effect can be more restrained with a reduction of an Nd content in an Nd:YVO4 crystal, but when a Nd content is smaller than 0.4 at.%, a single vertical mode is deteriorated, so that an Nd content is set larger than 0.4 at.%. Therefore, an Nd content is set more than 0.4 but below 0.7 at.%.
