Title: Ultrasonic transmitter/receiver
Inventor: YASUMATSU AKIO
IPC: G01F1/32
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive ultrasonic transmitter/receiver while enhancing the signal/noise ratio (S/N) by employing a diaphragm having surface profile of a collection of chevrons. SOLUTION: Vibration of an ultrasonic excitation signal is transmitted by a diaphragm 61 at a transmitting section into a fluid to be measured where it is subjected to phase variation due to Karman's vortex and vibrates a diaphragm 71 at a receiving section. A detector detects the phase in order to determine the number of generated Karman's vortex thus determining the flow rate of the fluid to be measured. Since the diaphragm 61, 71 has a surface profile composed of a collection of chevrons, a transmitting ultrasonic wave advances substantially in the direction of normal at each point of a triangle for transmitting the ultrasonic wave. Consequently, the reflected wave scarcely interfere with the transmitting ultrasonic wave. Furthermore, the diaphragm 61, 71 can have a flat surface as a whole and can be made thin.  Since the surface does not project from the wall face of a duct, flow of the fluid to be measured is not impeded.

Title: Soldering inspection method and device
Inventor: KANEZASHI YASUO
IPC: G01N25/72
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To improve an inspection accuracy by heating a measurement surface located near the terminal of a substrate, measuring temperature, and judging whether soldering is appropriate or not from the obtained temperature data. SOLUTION: Laser beams L being emitted from a pulse laser 13 based on a signal from a trigger device 11 heats the measurement surface of a substrate body 21 around the junction part between a lead 32 and a terminal 22 and the measurement surface of the substrate body 21 around the terminal 22. At the same time, the temperature of the substrate body 21 that is heated by a thermoviewer 14 starts to be measured. When the junction between the lead 32 and the terminal 22 is improper, heat at a temperature measurement part simply escapes to the substrate body 21, so that heat easily stays. Therefore, the maximum temperature increases as compared with a case where soldering is being made appropriately and at the same time a cooling speed is delayed.  In this manner, the maximum temperature or the cooling temperature at the temperature measurement part is measured and is compared with a predetermined threshold, thus judging whether soldering is appropriate or not.

Filed: 1979-12-18
Abstract: PURPOSE:To inexpensively produce an accurate diffraction grating with simplified process by making a mold with the transparent silicone resin injected between the diffraction grating matrixes and making a mold with the resulted diffraction grating as a matrix, by using a transparent molding material. CONSTITUTION:A molding material composed of a transparent silicone resin 3 is injected onto a diffraction grating matrix 1 formed with a diffraction grating 2 in a resin or the like by etching, whereby the mold of the diffraction grating 2 of the matrix 1 is made. Since the silicone resin 3 has excellent release characteristic, the molded resin 3 is easily stripped from the matrix 1. With this diffraction grating made of silicone resin as a matrix, the diffraction gratings are made in the same manner as mentioned above with various transparent resins. Since the silicone resin 3 withstands high temperatures, there is no deformation of the diffraction grating 2 when the resin is cast and since the molding is made many times with the same resin 3, the production cost is lowered.

Title: Throwaway wearing article and method for providing opening through film used therefor
Inventor: IGAUE TAKAMITSU
IPC: A61F13/15
Filed: 1990-06-22
Abstract: PURPOSE:To obtain a throwaway wearing article of full permeability and expansibility, good fitting properties and excellent softness by providing an expandable film with opening groups of specific opening rate each consisting of plural openings and partially existing through the film, and making the diameter of each opening less than a specific size. CONSTITUTION:A throwaway wearing article comprises at least a permeable surface sheet 6, a permeable reverse side sheet 7A, and a nonpermeable, expandable film 7B interposed between the sheets 6, 7A. Opening groups 14A, 15A of rate of opening 3 to 40% each consisting of plural openings exist at least partially through the expandable film 7B and also the diameter of each opening is less than 70mu. The opening groups 14A, 15A each consisting of such plural openings are thus provided, whereby permeability is obtained when the wearing article is worn. When each film is expanded by the intense exercise of a wearer, each opening is enlarged and permeability is increased so as to prevent generation of a rash even with much perspiration caused by the exercise. In addition, 7 each opening is limited within the hole diameter and thereby leakage of a body fluid from each opening does not easily occur even with expansion of each film during wearing, so providing excellent fitting properties.
