Title: Surface acoustic wave element and its manufacture
Inventor: YOKOTA HIDEAKI
IPC: H03H3/08
Filed: 1993-03-19
Abstract: PURPOSE:To obtain the surface acoustic wave element which is fast in the propagation velocity of a surface acoustic wave and high in its propagation speed and has excellent characteristics by forming a carbon film containing diamond of less than specific size as a surface wave propagation film. CONSTITUTION:The surface acoustic wave element 11 has the surface surface propagation film 14 and a piezoelectric film 15 on a substrate 12 in this order and also has an electrode 16 for applying an electric field to the piezoelectric film 15; and the surface wave propagation film 14 is the carbon film containing diamond of <=100nm mean crystal grain size. The film which is small in crystal grain size like this behaviors as a medium which is isotropic to a surface acoustic wave with short wavelength, so the phase of the surface acoustic wave is hardly disordered and excellent element characteristics are obtained. Further, the surface acoustic wave is not scattered by crystal grain borders since the extremely small crystal grain size, so the propagation loss becomes small. The effect can not be obtained when the mean crystal grain size of the diamond exceeds the range. The lower limit of the mean crystal grain size of the diamond is not specially determined, but the sound velocity tends to decreases remarkably when the mean crystal grain size is <=5nm.

Title: Analyzed for fiberlike particle in liquid
Inventor: YOSHIYAMA SHUSUKE
IPC: G01N15/14
Filed: 1991-03-26
Abstract: PURPOSE:To measure the length and diameter of a particle by passing fibrelike particles dispersed in a liquid through a minute pipe whose inlet and outlet are different in diameter, making the axes of the particles parallel with the main axis of the pipe, and detecting the scattering light of a particle. CONSTITUTION:Liquid where fiberlike particles 1 drift enters through an inlet 2 and gets out through an outlet 3 by a method in which pressure is added from the side of the inlet 2 or suction is conducted from the side of the outlet 3. As the diameter of the inlet 2 of this pipe is larger than that of the outlet 3, a pipe axis and that of a particle 1 become parallel with each other according as a particle 1 heads for the outlet 3 from the inlet 2. When the particles 1 is irradiated with light 4 whose the thickness of light passage is thin, a light scattering phenomenon is generated by a particle 1'' during a time that is from irradiation start at the tip of the particle 1'' to moving to the end. This scattering light is detected by means of a detector 5. The length of a particle 1 is calculated from a time detecting the scattering light and the movement speed of the particle 1. The diameter of a particle 1 is sought from the intensity of scattering on the basis of the theory of light scattering. As the thickness of the light 4 has relationship with resolving power, the thinner it is, the better it is.

Title: Circumferential welding device for pipe and pipe plate by laser
Inventor: YOSHIDA YASUYUKI
IPC: B23K26/21
Filed: 1986-04-15
Abstract: PURPOSE:To control profiling of a weld line with high accuracy and to permit high-quality welding with high efficiency by calculating and detecting the deviation of a welding head from the weld line from either of the inside circumference of a sensor position and the inside circumference of a pipe and feeding a correction signal to a driving device. CONSTITUTION:The output signals of two sensors 111, 112 on an x-axis are 111=0, 112=1 when the circumference of the sensor position and the inside circumference 9 of the pipe deviate. The result of the calculation 111-112<0 is then outputted and the welding head moves to the position 111-112=0 with the x-axis as a forward direction. The output signals of the two sensors 113, 114 on the y-axis are 113=1, 114=0 in said position and the result of the calculation 113-114>0 is outputted. The welding head moves on the y-axis to the position 113-114=0. The result of the calculation 111-112<0 is outputted in this position and the welding head moves on the x-axis to the position 111-112=0. The deviation between the circumference 10 of the sensor position and the inside circumference 9 of the pipe is thereby kept within an error range of the sensor 11. The positioning control is thus ended.

Title: Diaphragm type air pump unit
Inventor: SHIBATA NORINOBU
IPC: F04B45/04
Filed: 1978-07-17
Abstract: PURPOSE:To displace the first and the second diaphragm means vertically by the pressure difference between fluids introduced into the first and the second chamber by switch valves and the like for obtaining automatic pumping work only by giving fluid pressures. CONSTITUTION:When a rod 27 is displaced upwards, a valve means 22 is pushed anticlockwise by a shoulder part 29, and a valve part 26 is separated from a seat 25 to be seated on a seat 24. Consequently, the first signal chamber 20 and a signal pressure chamber 61 of a switching unit 50 are connected to the source of the open air. A negative pressure is introduced into the second signal chamber 21 of an air- pump unit 10 through ports 55 and 56. By the pressure difference between fluids in two chambers 20 and 21, the first and the second diaphragm parts 19 and 36 are displaced downward. Thus, the capacity of the second pump chamber 35 is reduced, and that of the first pump chamber 34 is increased for sucking in air. Subsequently, compression work is given by the downward displacement of the rod 27 for making smooth pumping work automatically.

Abstract: PROBLEM TO BE SOLVED: To make an outer edge more flexible and elastic and more operative than other portions and to make it possible to clean or wash fine parts, etc., over a wide range by rolling a conical fiber part disposed at a stem end and forming its outer edge as an extremely thin sheet. SOLUTION: The swab 1 is provided with the fiber part 3 at the end of the stem 2. The fiber part 3 is provided by winding a fiber body consisting of cotton fibers, chemical fibers or their mixed fibers, etc., around the end of the stem 2. The fiber part 3 is formed to a conical shape and is then rolled to a flat shape. Its outer edge 3a is formed as the extremely thin sheet and is formed like an arrowhead flattened over the entire part of the fiber part 3. The swab can, therefore, be intruded into the fine parts of a precision machine, etc. The outer edge 3a is formed as the extremely thin sheet and since its tip is formed to an acute angle, the outer edge 3a can be easily intruded into particularly narrow grooves and fine holes to adhere and remove the stains, such as dust, dirt, oil and water with the fiber part 3.  The cleaning of the fine parts by impregnating the swab with a cleaning liquid, such as methanol, is possible as well.
