Abstract: PURPOSE:To enable recognition of a three-dimensional position even of a dynamic object by recognizing three-dimensionally the position of the object to be measured by utilizing a reflected light from the object. CONSTITUTION:Each of a plurality of light-emitting points of a light source 11 is driven to be lighted by a pulse in time division at each prescribed rotational angle of the respective optical axes of a light-projecting lens 12 and a light- receiving lens 17, and a light beam emitted from the light source 11 is scanned one-dimensionally in the direction of the axis Y. Besides, an eccentric cam 24 rotates synchronously with this lighting drive by the pulse, so as to rotate each optical axis, and thereby the light beam is scanned two-dimensionally in the direction of the axis X. Scanning angles thetax and thetay to the axes X and Y of the light beam applied onto an object to be measured can be known from the position of emission of each light-emitting point and an output pulse signal of a rotary encoder.

Title: Power supplying apparatus
Inventor: YAMAZAKI HIROYOSHI
IPC: H01F38/14
Filed: 1988-11-01
Abstract: PURPOSE:To enable safe transfer of energy by transferring with a secondary coil the energy of high-frequency electric power generated from an inverter etc., and placing an insulating material between a primary coil and the secondary coil. CONSTITUTION:A secondary coil 40 to supply electric power to a load is installed opposite to a primary coil 22. The primary coil 22 is joined to the secondary coil 40 by electromagnetic coupling through an insulating material 50 of a non-magnetic material. When an inverter B is operated and a high-frequency electromagnetic field is generated around the primary coil 22, this high-frequency electromagnetic field is transferred to the secondary coil 40 through the insulating material 50. Thereby high-frequency voltage is induced in the secondary coil 40 and heats the load 36 such as a cooking pan, Energy can thus be converted into heat energy and transferred from the primary coil 22 to the load. The electric power is thus supplied to the load by using the high-frequency voltage induced from the primary coil 22, driven by the inverter B and generating the high-frequency voltage, and generated in the secondary coil 40; therefore, the energy can be transferred safely. The secondary coil 40 has a degree of freedom of design to generate required voltage, therefore, is available for various loads.

Filed: 1994-11-10
Abstract: PURPOSE: To detect the degradation of road environment without using an exclusive sensor or judge the failure of a distance sensor without needing two distance sensors so as to secure the reliability of control while reducing cost. CONSTITUTION: A travel control device for an automobile is provided with a laser radar for detecting inter-vehicle distance between an own vehicle and a preceding vehicle and performs auto-cruise according to the inter-vehicle distance detected by the laser radar. The output power of the laser radar is measured, and outside air temperature is estimated on the basis of the temperature characteristic of output power. When the outside air temperature is in an area of not lower than the temperature where the output power of an optical distance sensor is lowered to the specified value or less, or in an area of the road surface freezing temperature or lower, the road environment is judged to be bad, and auto-cruise is stopped.  Reflecting bodies are disposed being spaced by the specified distance in front of the laser radar, and laser beams are emitted to the reflecting bodies from the laser radar to measure the distance and reflecting quantities between both reflecting bodies. When at least either one of the measured distance and reflecting quantity is out of an allowable range, the failure of the laser radar is judged, and auto-cruise is stopped.

Abstract: PURPOSE:To reduce a shearing stress to be applied to a solder joint and to increase its life by providing a standoff ensuring metal foil opposing to the lower surface of a surface mounting component between lands, and providing a component lifting solder on the foil. CONSTITUTION:A standoff ensuring metal foil 21 opposed to the lower surface of a surface mounting component 15 is provided between lands 13, solder paste coating the foil 21 reflows simultaneously at the time of reflow soldering on the lands 13, and the melted solder on the foil 21 lifts a body package of the component 15 having insufficient wettability while holding a predetermined shape by surface tension as component lifting solder 22, and hence a large standoff value H is obtained between the land 13 and the conductive part 16 of the component 15. When the core board is exposed to an operating temperature or an environmental temperature to be repeatedly raised or lowered, a shearing stress functions at the core 11 having large linear expansion coefficient and the component 15 having small linear expansion coefficient, but this stress is dispersively absorbed by the joint 14 having a sufficient thickness based on the large value H.

Filed: 1988-11-04
Abstract: PURPOSE:To obtain the drum head with hitting strength and to generate a light sound with clear higher tones by using a sheet of para-orientation type aramid which has >=25kg/mm<2> tensile strength and a >=600kg/mm<2> tension elastic modules. CONSTITUTION:This drum head is made of the sheet of para-orientation type aramid which has >=25kg/mm<2> tensile strength and a >=600kg/mm<2> tension elastic modulus. The para-orientation type aramid consists substantially of units selected in a group of constituent units shown by formulas I. In the formulas, Ar1-Ar3 are bivalent aromatic groups and substantially equivalent mol. The para-orientation means that bonds which developing molecule chains are positioned coaxially or in parallel in the opposite direction of aromatic nuclears. Consequently, the lightweight film with high strength and a high elastic modulus is used, so the drum head is resistive to hitting and generates a light sound with clear higher tones.

Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To nondestructively measure track meandering of a recorded track on a recorded magnetic tape. SOLUTION: The recorded magnetic tape recorded with tracks inclined in a prescribed direction by an ordinary magnetic recording and reproducing device of a helical scan system is helically wound around a rotary drum 30 to rotated integrally with rotary heads 34 in the measuring magnetic recording and reproducing device 10B where almost no track meandering takes place, and is traveled. Under this state, the rotary heads 34 are stepwise shifted in the longitudinal direction on the magnetic tape 2A.

Afterward, a digital data based on the FM envelope value is arithmetically processed in a personal computer 50, and hence track meandering on a track recorded on the magnetic tape 2A is nondestructively measured.

IPC: G06T7/00
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To prevent mismatching under the influence of a background, halation, etc., and recognize only an object which should be recognized. SOLUTION: The variance value S1 of extracted image data II is calculated and it is decided whether or not the variance value SI is larger than a variance threshold Ts (116 and 118). When SI<=Ts, the extracted image data are image data having small variation in the light and shade of a background part, etc., so subsequent processing is not performed. When SI>Ts, a normalization correction coefficient R is calculated and when R>TR, the extracted image is highly correlated with a template, so it is judged that the image matches, thereby storing the normalization correlation coefficient R and the center coordinates (Xc, Yc) of the template.
