Title: Surface acoustic wave resonator
Inventor: MAEDA SHIGENORI
IPC: H03H9/25
Filed: 1990-05-21
Abstract: PURPOSE:To obtain a surface acoustic wave resonator with an excellent reso nance characteristic by providing some relation between which of comb-shaped electrodes and width of reflecting electrodes, respectively. CONSTITUTION:In the case where a pitch P between comb-shaped electrodes 12a1, 12b1 and electrodes of reflecting electrodes 13, 14, respectively is set to 1/2 of wavelength lambda of the surface acoustic wave resonator, and also, width of the respective electrodes of the electrodeless 12a1, 12b1, and width of the respective electrodes of the electrodes 13, 14 are denoted as WT and WG, respec tively, the equation 0.54<WT/P WG/p<0.62 is satisfied. That is, by making width Wt of excitation electrodes 12a1, 12b1 and width WG of the reflecting electrodes 13, 14 within a range for satisfying 0.54<WT/P WG/P<0.62, the figure of merit M becomes larger. In such a way, the surface acoustic wave resonator comes to generate easily an oscillation, and also, since a resonance resistance R can be lowered, the surface acoustic wave resonator with excellent characteristic can be obtained.

Title: Quality testing method and quality managing method for concrete
Inventor: YONEZAWA TOSHIO
IPC: G01N11/06
Filed: 1988-05-26
Abstract: PURPOSE:To easily manage the quality of high strength concrete by measuring the settlement of concrete in a reservoir part, or the moving amount of concrete in a flow part, and the drift velocity of concrete. CONSTITUTION:At the time of executing a quality test of concrete, a vertical part 10 is filled with concrete of a prescribed quantity in a state that an opening 16 has been closed by a partition plate 14, and subsequently, by drawing up the partition plate 14, concrete is allowed to flow to a horizontal part 12 from the opening 16. In this case, a time point when a deformation of concrete is started is a time point when the partition plate 16 has been drawn up, and a time point when the deformation of concrete is ended is a time point when the movement of concrete in the horizontal part 12 has stopped, and both of them can be discriminated clearly. In this state, by measuring a moving amount of concrete in the horizontal part 12 at the time point when the deformation of concrete has been ended, a yield value is derived. Also, by dividing the moving amount by the time extending from the time point when the partition plate 14 has been drawn up to the time point when the movement of concrete has stopped, and measuring a drift velocity of concrete, viscosity is derived.

Title: Semiicontinuous manufacture of high purity silicon
Inventor: YOOZEFU DEIITORU
IPC: C01B33/02
Filed: 1980-09-19
Abstract: Pure silicon is obtained in a cyclic process by reducing quartz sand with aluminum; the finely divided quartz is dissolved in an aluminum sulphide slag and is reduced by molten aluminum. The molten aluminum also serves as a solvent for the elemental silicon which crystallizes out and precipitates as the temperature falls. Aluminum oxide formed during the reduction is extracted from the slag and passed on for melt electrolysis in order to recover the aluminum.

Filed: 1981-08-21
Abstract: PURPOSE:To obtain an orienting film material which can provide an orientation controlling film only at an optional and prescribed place with good heat resistance and without contaminating a sealed part, by using a substance contg. a silane modified silanol oligomer contg. a long-chain alkyl group. CONSTITUTION:A silanol oligomer is called generally as a spin-on-glass (SOG), and a coating film is formed from a solution and then this is calcined with high temp. to prepare a silicon oxide film and therefore it has essentially high heat resistance. A long-chain alkyl (CnH2n+1: here n=8-20) is introduced to a side chain in order to give water repellency. By such a way, the long-chain alkyl group is bonded with silanol skeleton and stabilized, and therefore even if it is subjected to a high temp. treatment, this bonding is not cut and holds water repellency and is made to an orientation controlling film having high heat resistance.

Abstract: PURPOSE: To make an adsorbent bed smaller in size and longer in life by supplying dried air to the adsorbent bed in order to desorb one component from the adsorbent bed and ventilating the air and the desorbed one component when aircraft reaches a height at which the dry ambient air is available. CONSTITUTION: An air entrance port 13 is connected to a compressed air source, a vent 14 to the atmosphere and a feed line 22 to an equipment in an aircraft. The air from a feed source containing water vapor is subjected to adsorption of the water vapor in the adsorbent bed 10 by manipulating a rotary valve 16 before or during a takeoff and a ball 18 is moved to an open position by the dry air to send the dry air by the feed line 22 to an apparatus. When the aircraft obtains the height, the rotary valve 16 is manipulated to a second position and the dry compressed air passes a bypass 15 from the air entrance port 13 and emerges directly to the feed line 22. Some air enters an outlet 12 and acts to press the ball 18 to a seat 19 to close the outlet 12.  The air passes a passage 20 and an orifice 21 and reduces the pressure, thereby desorbing the material deposited in the adsorbent bed 10. The air is then discharged outside the aircraft from the vent 14.
