Title: Method of soldering electronic component
Inventor: CHIBA KOICHI
IPC: H05K3/34
Filed: 1987-07-16
Abstract: PURPOSE:To enable lead terminals of an FP element or the like to be soldered on predetermined circuit terminals on a circuit board by means of irradiation of laser beam, by controlling an angular velocity of rotation of a reflection plate such that the laser beam illuminates and scanns the surface at an approximately constant linear velocity. CONSTITUTION:Lead terminals 22a of a flat-package-type electronic component 22 mounted on a circuit board are soldered on predetermined circuit terminals on the circuit board. During this soldering, a laser beam is applied to the section to be soldered with its illumination angle theta varied continuously by rotating a reflection plate 26, while the angular velocity of the rotation of the reflection plate 26 is controlled such that the laser beam scanns the surface at an approximately constant linear velocity. In this manner, the aligned lead terminals can be heated and soldered with an approximately equal amount of heat whereever the lead terminals are located in the row, in the central region or at the ends thereof.

Filed: 1986-07-30
Abstract: PURPOSE:To permit high-speed fixing with lower electric power consumption by transferring a toner image transferred onto a primary transfer medium to a secondary transfer medium having a heat source is the inside, then transferring and fixing said image to transfer paper. CONSTITUTION:The toner image on a photosensitive belt 1 is primarily transferred onto an intermediate transfer medium 2 moving in a direction (b) by a non-electrostatical method; i.e., by superposing the belt 1 and the intermediate transfer belt 2 and passing the belts between a supporting roll 11 and a press roll 12. The toner image on the primary transfer medium is then transferred onto the secondary transfer medium 14 consisting of heating roll structure having the heat source in the inside by passing said medium between the secondary transfer medium and a supporting roll 13. The toner image on the secondary transfer medium is transferred and fixed to the transfer paper by pinching the transfer paper 3 in the heated state and pressing the secondary transfer medium by a pressuring roll 16. The high-speed fixing is thereby permitted with the lower electric power consumption.

Title: Method and device for measuring concentration of soil containing volatile organic chlorine compound or water
Inventor: SATO TAKAO
IPC: G01N30/00
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To easily specify the type and contamination concentration of a contaminant by controlling temperature stepwise by a temperature-controlling means, using the difference in boiling points, separating a plurality of substances contained in a measurement target sample, sucking gas, and measuring the type and concentration of the gas. SOLUTION: A measurement target sample is loaded into closed columns 11-1n for closing, and gas being vaporized by changing the temperature of the inside stepwise is taken out of a breathing pipe Ln. Then, the sample of which column is to measured is determined, and all of unloading control valves are closed. Then, purge valves PV1 and PV2 are opened, and gas for cleaning up the inner surface of piping is allowed to flow from a pump 2 to a header HD via C1 and is unloaded from an exhaust pipe Ex, thus preventing cross contamination by a target. When the clean-up is completed, PV1 and PV2 are closed and a valve SM is opened, thus allowing gas in the column 11 to be taken by a gas type/concentration-measuring means MS via a suction pump P1 for measurement.

Title: Actuator structure
Inventor: MIHARA TAKAHISA
IPC: G11B21/02
Filed: 1984-08-28
Abstract: PURPOSE:To avoid a deformation due to temperature stress by fixing one end of the joint of the housing of a carriage holding part and a magnetic circuit for swinging an oscillating shaft and bringing the other end contact through a roll. CONSTITUTION:A housing 13 fixes an arm 2 having a magnetic head 1 disposed opposite to a circular plate 11 to an oscillating shaft 12, and a magnetic circuit 14 swings said shaft 12. One end of a joint between the shaft 12 and circuit 14 is fixed, while the other end is fixed with a screw 17 and a keep plate 16 through a roll 15. The change in the vertical direction of the housing, which is caused by the difference between materials of the housing 13 and the magnetic circuit 14 and that between coefficients of linear expansion, arises along the roll 15, whereby the temperature stress will not occur in the housing 13 by less friction. Moreover, the bottom of the housing 13 holds the fixed contact surface of the magnetic circuit 14, while the top comes contact with the magnetic circuit 14 in the longitudinal direction of the roll 15, and both the housing 13 and said circuit 14 are formed in one body; therefore the titled actuator has the rigidity and its resonance frequency drops hardly. Thus the structure that the temperature stress will not occur at the joint of both of them can be obtained.

Title: Diversity receiver
Inventor: SASA ATSUSHI
IPC: H04B7/02
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a receiver by calculating the frequency of use per fixed time, performing demodulating operation while selecting only a certain demodulation part of which the frequency of use is higher than a specified value, and stopping the demodulating operation at the other demodulating part. SOLUTION: The compared result signals of a comparator 305 are added for fixed time by a cumulative adder counter 101 so that the frequency of use per fixed time at respective demodulating parts 307 and 308 is calculated. When the demodulating part of which the frequency of use gets higher than the specified value is the demodulating part 307, such a demodulating part 307 is determined as the demodulating part to be used. Then, the inputs of received signal and operating clock to the other demodulating part 308 are cut off, its demodulating operation is stopped, and only the single demodulating part 307 is turned into the receiving state. In this case, when the demodulating part 308 under demodulating operation stop is started again, a reception-synchronizing signal is succeeded from the active demodulating part 307, so that received signal synchronism is held.  As a result, the power consumption of receiver is reduced, and the burden of power source or the like during stop or at the time of low-speed traveling is reduced.

Title: Combustion apparatus
Inventor: OKADA KIYOMI
IPC: F23C99/00
Filed: 1981-11-10
Abstract: PURPOSE:To prevent the damage of a dust removing cap by coating the projected part of a combustion gas take-out pipe to a combustion gas take-out chamber with a dust removing cap made from a refractory material, in the titled combustion apparatus for a heat source for hot water feeding, room heating and the like using a powdery solid fuel. CONSTITUTION:Combustion gas ejected through a shaft part communicating port 10 makes a heavy collision with the outside of an end wall 39a of the dusting cap 39. However, since the dust-removing cap 39 is constructed from a heat- resisting material, it is not easily damaged even when exposed to a high heat. Further, combustion gas of high temperature and high pressure finally enters within the cap 39 through a ventilating port 40 formed at a part below a peripheral wall 39b of the dust removing cap 39, and is taken out of a combustion gas take-out pipe 38. Since the ventilating port 40 is formed at the lower part of the dust removing cap 39, there is scarce possibility that burnt ashes, particularly, unburnt parts having weight reach the take-out pipe 38, and hence it is possible to take out clean and pure combustion gas.

Title: Device and method for detecting obstacle on road, systems for monitoring road condition and obstacle on road, and record medium storing program for detecting obstacle on road
Inventor: KAJIKI JUNKO
IPC: G01S13/56
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To detect an obstacle hidden by another object. SOLUTION: The obstacle-detecting device checks to see if there is an obstacle being hidden temporarily by another object according to history information for indicating the detection history of the object (S19). When it is estimated that there is an obstacle hidden by another object, the background data of a specific region including the hidden obstacle is updated, thus storing an obstacle hidden temporarily by another object also in the background data and hence more accurately detecting the obstacle using the background data.
