Title: Production of regenerated aggregate from cement concrete lump
Inventor: HYODO KAZUYA
IPC: C04B20/00
Filed: 1995-07-11
Abstract: PURPOSE: To improve quality and yield and to suppress the formation of fine powder having no applications by heating and crushing or crushing and heating the cement concrete lumps produced after disassembly of buildings, then subjecting the aggregate itself to lapping and grinding. CONSTITUTION: The cement concrete lumps produced at the time of disassembling the cement concrete structures are crushed by a crushing machine to the max. size of the aggregate included therein or below (a grain size of about 80 to 20mm) and are then heated to 100 to 600 deg.C by a heater or after the concrete lumps described above are heated to 100 to 600 deg.C, the concrete lumps are crushed to the max. size of the aggregate included therein, and thereafter, the cement mortar components sticking to the surfaces of the coarse aggregate are removed by the grinding effect generated when the aggregate itself is lapped against each other by vibration and rotation of a mill. The aggregate particles of a grain size above 5mm are then removed by classification, by which the regenerated coarse aggregate is obtd.  The aggregate particles below a grain size 5mm are processed by a paste removing device and classifying machine, by which the fine powder below 0.15mm is removed and the regenerated fine aggregate of 5 to 0.15mm is obtd.

Title: Laminated high voltage semiconductor rectifying element
Inventor: IDE TETSUO
IPC: H01L25/07
Filed: 1985-08-09
Abstract: PURPOSE:To avoid degradation of rectification characteristics caused by the temperature rise even if a large current is rectified by a method wherein diode chips are laminated while holding other diode chips, which have smaller forward voltage drops than ones in the large current range, between them. CONSTITUTION:A diode chip 1 is made from an N-type silicon substrate with a specific resistivity of 25-30OMEGAcm like a conventional one and the thickness of its N-type layer is 120-140mum. On the other hand, a diode chip 11 which is held between such diode chips 1 is made from an N-type silicon substrate with a specific resistivity lower than that of the diode 1, for instance 5-15OMEGAcm and the thickness of its N-type layer is as thin as 60mum to reduce a forward voltage drop is a large current range. Therefore, the heat generated in the diode chip 11 when a large current is rectified is small and radiation of the heat generated in the other diode chip 1 is eased. With this constitution, a laminated high voltage semiconductor rectifying element which facilitates high voltage rectification of a large current with high frequency driving can be obtained with a low cost.

Abstract: PURPOSE:To obtain a self-traveling carriage which enables reduction in size and simplification by providing a pair of guide arms for profile traveling, a pair of driving wheels, an electromagnet and a device for moving a welding torch. CONSTITUTION:When a guide arm 25 in a front part is made shorter than a guide arm 25' in a rear part, the advacing direction of a carriage 20 approaches to a vertical plate 12 and when the arm 25 abuts against the plate 12, the carriage 20 is stopped and advances along the plate 12. When the carriage arrives at a crossing part B, the carriage is detected by a sensor 26 which energizes an electromagnet 24. The electromagnet 24 which is kept lifted is then attracted to a bottom plate 10. A driving wheel 22 on the non-weld line side is changed over to an electromagnetic clutch for backward rotation, by which the wheel is rotated backward. The arms 25, 25' are unlocked so that the arms can rotate freely and therefore the carriage 20 begins to spin. The carriage 20 assumes the same attitude for the plate 11 as the attitude for the previous plate 12 when the carriage spins 90 deg.. The arms 25, 25' are locked again and the electromagnet is de-inergized. The wheel 22 is changed over by the electromagnetic clutch for rectilinear movement so as to rotate forward again. The carriage starts advancing along the plate 11.

Title: Flow sensor element
Inventor: YAMAGUCHI TAKAYUKI
IPC: G01F1/692
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To accurately and easily take a measurement in a low flow-rate range. SOLUTION: In the flow sensor element equipped with at least one substrate 1 and a thin-film heating element 3 formed on the substrate 1 while thermally insulated from the substrate 1 and extended at right angles to the flow direction of fluid, the width (a) of the heating element 3 in the flow direction of the fluid is so set that there is no effect of the conduction of heat in the heating element 3 due to the flow of the fluid. Consequently, when the heating body 3 is heated, the conduction of the heat in the heating element 3 is suppressed to make it easy to conduct the heat of the heating element 3 to the fluid. Consequently, the disorder of the linearity of the relation between the flow velocity of the fluid and output variation corresponding to the temperature variation of the heating element is improved to accurately and easily take a measurement in the low flow rate range.

Title: Method for grinding wafer
Inventor: TAKAHASHI KAZUHIRO
IPC: H01L21/304
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To manufacture an extremely thin IC chip with a high yield, by grinding the rear surface of a wafer while adhesive sheets are stuck to the front surface of the water after the adhesive layers of the sheets are cured by irradiating the adhesive layers with energy rays. SOLUTION: An adhesive sheet cured by energy ray is stuck to the surface of a wafer on which a circuit is formed. Then, another adhesive sheet cured by energy ray is stuck to the surface of the circuit on the wafer. Each cured sheet by enngy ray is composed of a base film and an adhesive layer cured by energy ray formed on the base film. Then, the adhesive layers are irradiated with energy rays so as to cure the adhesive layers while the layers buffer the recessing and projecting sections of the circuit. When the rear surface of the wafer is ground in such a state, the wafer can be ground to a uniform thickness without receiving any influence from the recessing and projecting sections on the surface of the wafer, because the recessing and projecting sections are buffered by the deformation of the adhesive layers.
