Inventor: MURATA MASAYOSHI
IPC: G01P5/22
Filed: 1985-09-30
Abstract: PURPOSE:To obtain a quick, secure, highly accurate, and energy-saving measurement instrument handling not only a regular flow but also an irregular flow by providing the 1st and 2nd photoelectric transfer elements disposed a certain distance away from a fluid in the flow direction of said fluid to be measured, which is installed in parallel with a display, and an arithmetic circuit obtaining the speed distribution of a shading particle. CONSTITUTION:A video camera 9 receives the airlight of the shading particle 2, forms and records its image, and the same video is displayed on the 2nd CRT11. A speed detection probe 12 installed close to the screen of the 2nd CRT11 converts the video of the shading particle appearing on the screen into a voltage corresponding to a change in light intensity. The output signals of the 1st and 2nd photoelectric transfers 14 and 15 are inputted to correlation meter 13. From the output signals the correlation meter 13 calculates the mutual correlation co-correlation coefficient is maximized is obtained and displayed, whereby the speed of the shading particle on the CRT is available.

Abstract: PURPOSE:To decompose and dissipate ozone by making the ozone retained in a machine by providing a guiding member which regulates the sending direction of discharged air by an air blower for cooling the inside of the machine and making the ozone leaked from a gap communicating the inside to the outside of the device retained in the machine. CONSTITUTION:A housing 40 constituting an optical system cooling fan 29 is provided with U-shaped ducts 31 and 32 at both ends of a fan, and a motor 33 is arranged in the duct 32. The air blower means for sending cooling air to a heat generating member by sucking outside air is formed of the fan 29, the U-shaped ducts 31, 32 functioning as the guiding member for the discharged air of the fan 29 in the air sending direction, and the housing 40. The air flow F4' including the ozone from the conventional ozone generating source (electrostatic chargers 3, 6 and 7) is not generated by the divided flows F2, F3 of the U-shaped ducts 31, 32, and becomes retaining flow F4 as shown in Figure. Thus, the air with high ozone concentration mechanically is retained, and the ozone is not rapidly discharged to the outside of the machine as in the conventional device, and the ozone is removed due to the natural dissipation of the ozone while it remains in the machine and the decomposition of the ozone by a temperature in the machine.

Title: Electrode structure of piezoelectric element
Inventor: MATSUOKA MIKIYA
IPC: G01L1/16
Filed: 1991-08-29
Abstract: PURPOSE:To prevent the exfoliation of a silver electrode from a piezoelectric element due to soldering. CONSTITUTION:To the upper surface of a metal plate 3 a silver electrode 4 is bonded, to the upper surface thereof a PZT element is bonded, to the upper surface thereof the other silver electrode 6 is bonded, and to the upper surface thereof lead wires 7 are fixed by soldering. The side of each of the silver electrodes 4, 6' the side connected with a PZT element 5 is formed as rhodium containing layers 9, 10. The opposite side of each of the silver electrodes 4, 6, the side not connected with the PZT element 5 is formed as pure layers 11, 12 composed of almost pure silver. Thus each of the silver electrodes 4, 6 is constituted as a two-layered structure. As the result, in the rhodium containing layers 9, 10, the diffusion rate of tin to silver is decreased. In the pure layers 11, 12 which are not connected with the PZT element 5, diffusion of tin is excellent, and soldering of the lead wires 7 is easy. In the rhodium containing layers 9, 10 connected with the PZT element 5, the diffusion of tin becomes difficult to reach the interface between the layers 9, 10 and the PZT element 5.

Title: Modification of iron slag
Inventor: HASEGAWA KAZUO
IPC: C04B20/10
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To modify iron slag so that it may not produce alkaline water by contact with rainwater by spraying iron stag with a specific water under a specific condition in air. SOLUTION: In air, iron stag is sprayed with the water of which pH is adjusted to 4.5-5.0 with sulfuric acid once every two days at a rate of 5-10dm<3> / ton of the stag, preferably over 5 months. The iron slag has preferably particle sizes of 80-20mm economically. The reason why the iron slag produces alkaline water by contact with rainwater is that quicklime distributing on the slag surface dissolves in water. Thus, the quicklime is converted to calcium sulfate by neutralization to inhibit the formation of alkaline water. Accordingly, the restriction of use of iron slag as a road material is released in the area that, the alkali gives adverse effect on the underground water.
