Title: Semiconductor device and manufacture thereof
Inventor: ISOBE YOSHIHIKO
IPC: H01L27/04
Filed: 1989-09-20
Abstract: PURPOSE:To prevent cracks from occurring to a passivation film of silicon nitride so as to improve a semiconductor device in reliability by a method wherein a thin film resistor is sandwiched between oxide films. CONSTITUTION:A thin film resistor 3 is formed of sublimate, and it is interposed between a first and a second oxide film. When a current is made to flow through the resistor 3 to fuse, the sublimate is fused or sublimated to penetrate easily into the first and the second oxide film but not into a silicon nitride film 7, so that the thermal effect on the silicon nitride 7 is relaxed by the first and the second oxide film. By this setup, the cracks of the silicon nitride 7 caused by melting hardly occur and a semiconductor device of this design can be improved in reliability.

Abstract: PURPOSE:To enable the removal of a multiple reflection of an ultrasonic wave by making a curvature ratio in an array direction on an internal bottom surface formed in a body case smaller than the curvature ratio of a tip face of a vibrator unit to arrange an ultrasonic absorption member on a side wall of the body case. CONSTITUTION:In an ultrasonic probe for picking up a three-dimensional data, a curvature ratio along the length of an internal bottom surface 12A is made smaller than that along the length of a tip face 18A of a vibrator unit 18 while an ultrasonic absorption member 44 is arranged on a side surrounding wall of a medium tank 38.

As a result, a multiple reflection of the ultrasonic waves can be absorbed between the tip face 18A of the vibrator unit 18 and the internal bottom surface 12A of the body case 10 to remove undesired noises accompanying picking up data effectively while allowing the formation of a clear image.

Title: Exposure construction method for aggregate in concrete paved surface
Inventor: KAWASHIMA HIROYUKI
IPC: E01C7/14
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide an exposure construction method for an aggregate, by which the progress of setting reaction of cement is delayed without much influence of a weather such as a rainy weather or the like to easily conduct a work of precutting mortar for exposing the aggregate, thereby easily obtaining the exposed surface of a uniform texture depth.

Abstract: PURPOSE:To prevent abnormal noise from generating from part of a burner unit, without spoiling the effect of an improvement in combustion characteristics, by increasing a combustion range by omitting small holes which face to burner ports for ignition among small holes provided on earth plate. CONSTITUTION:Part of assist combustion air being supplied through through- holes 17a provided in the lower part of a frame cylinder 17 as part of air from a propeller fan, flows into a gap between burner ports 10 and an annular wall 15b, passing through small holes 16 provided on the horizontal part 15a of an earth plate 15, promoting combustion reaction. At this time flames 18 formed on the burner ports 10 for ignition grow largely, colliding against the annular wall 15b of an earth plate 15. But the flames 18 flow upward without blowing out, because there are no small holes 16 on the horizontal part 15a of an earth plate 15. Accordingly abnormal noise which generates when flames flow out from the small holes 16 of an earth plate 15 can be prevented.
