Title: Production of ferroelectric wafer
Inventor: ITO KUNIHIRO
IPC: C23F1/00
Filed: 1994-06-30
Abstract: PURPOSE:To etch the wafer having small warpage in a high yield through preventing the cracks in the wafer from being generated by adjusting the difference in temp. between the wafer and the etching solution to a value within a specified range at the time of carrying the wafer into and out of an etching solution. CONSTITUTION:In this production, a ferroelectric wafer such as 36 deg. Y-cut lithium tantalate or 64 deg. Y-cut lithium niobate single crystal wafer, etc., is subjected to etching treatment with a heated etching solution such as hydrofluoric acid/ hydrochloric acid mixture, etc., while preventing the warpage of the wafer from being generated. At this time, tanks stepwise heated or cooled to intermediate temp. are disposed in front and in the rear of the etching tank. The wafer to be subjected to etching treatment is carried into and out of the etching tank through these front and rear tanks and thereby the difference in temp. between the wafer and the etching solution at the time of carrying the wafer into and out of the etching tank is adjusted to <=35 deg.C. Thus, the warpage of the wafer becomes smaller and also the generation of cracks in the wafer due to the etching treatment is remarkably reduced.

Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To achieve a shortening of preheating time, a restriction of the generation of tar and the checking of clogging attributed to the generation of the tar at a vaporization part of a liquid fuel combustion apparatus. SOLUTION: An excitation coil 19 is wound on the outer circumference of an outer tube 15 provided with a nozzle part 20 at one end thereof and a fuel supply port 21 at the other end thereof, a porous body 16 and a shaft body 17 are arranged in the outer tube 15 below the center part of the porous body 16 so that the quantity of received heat below the porous body 16 is made larger than the quantity of the received heat above the porous body 16. Self heat generation by an induction current in the outer tube 15, the porous body 16 and the shaft body 17 allows increase in a temperature rasing speed of the vaporization part 14. The porous body 16 is heated to the diametrical inner circumference side by heat transferred from the shaft body 17 to promote the vaporization of a fuel with a better temperature distribution thereby restricting the generation of tar.  The quantity of received heat below the porous body 16 is made larger than that of the received heat to raise the temperature of a lower part of the porous body 16. The vaporization is promoted also below the vaporization part 14 thereby restricting clogging caused by the tar.

Filed: 1979-11-16
Abstract: PURPOSE: To reduce moisture of materials, by releasing heated and compressed materials from the compression state and ejecting contained moisture as vapour by providing two taper parts in the screw body and providing the transfer part and the air suction hole for it.  
     CONSTITUTION: Materials such as sewarage sludge supplied from supply hole 3 are compressed between filtering screen 6 of casing 1 and the first taper part 31 of screw body 25. During this time, they are heated by heating means 13 and 36 to lower viscosity of the liquid, and they are dehydrated efficiently. Caked and heated  materials get out of shape in the position of air suction hole 9 where screw body 25 is small-diameter, and moisture in materials becomes vapour and is sucked into suction hole 9. Materials made into flakes by promoting dehydration are compressed between the second taper part 32 and cylindrical casing 2 by screw blade 26 and are ejected from ejection hole 14. As a result, the contained moisture rate of the cake is reduced and is unified.

Abstract: PROBLEM TO BE SOLVED: To obtain a flowmeter which reduces a thermal ciphon effect by arranging a slender member along a flow passage inside a sensing conduit separatedly from a first sensing member and a second sensing member so as to marrow a fluid flow space inside the sensing conduit. SOLUTION: A wire 34 is set at a length which does not come into contact with a thermosensitive region when it is inserted into a prescribed position inside a sensing conduit 32. A mass flowmeter 30 is operated when an upstream- side coil 44 and a downstream-side coil 46 are connected to a bridge circuit. When a gas flows, the upstream-side coil 44 is cooled by the flow of the gas, heat is carried by the gas, the downstream-side coil 46 is heated by the heat carried by the gas, and a temperature difference is generated. The temperature difference between the up-stream-side coil 44 and the downstream-side coil 46 is measured by the number of gas molecules, i.e., by the mass of the gas flowing through the sensing conduit 32. The wire 34 which is arranged on the upstream side 38 and the inside 36 of the sensing conduit 32 outside the thermosensitive region 42 reduces a fhuid region inside the upstream part 38, and a thermal ciphon effect can be reduced to a minimum.

Title: Color arranging method
Inventor: NAKAJIMA NORIHIRO
IPC: G06T11/00
Filed: 1987-06-18
Abstract: PURPOSE:To avoid misrecognition by using an information reading means, a statistic analyzing means, a dictionary data reading means, a color arrangement deciding means, and a display information generating means to constitute an internal processing means of an information processor. CONSTITUTION:An information reading means 5 extracts the numerical data information and the attribute data on the numerical data out of the information storing devices 1 and 2. A dictionary data reading means 7 extracts the dictionary data corresponding to the attribute data. Then a color arrangement deciding means 8 defines the maximum and minimum values of the numerical data and the mean value information as the feature values related to the distribution state of numerical values. Then the means 8 decides the color arrangements corresponding to those feature values as well as the color change between the color arrangements as the color arrangement information on a specific state among those dictionary data referred to by the attribute data and also decides the color information when a certain stage changes to the next stage of different distribution density from one stage. A display information generating means 9 adds the color arrangement information to the display data based on the decided color arrangement information and displays them on a display device 4. Thus the misrecognition can be avoided for color arrangement.

IPC: H05K13/02
Filed: 1980-10-27
Abstract: PURPOSE:To align elements separately showing their face and rear with high efficiency by a method wherein a ferromagnetic metal is incorporated into only one of the metal electrodes provided in the main face and rear surfaces of the element so  as to distiguish the rear surface from the face one by bringing a magnetic close to  the metal electrode from above. CONSTITUTION:An Al electrode 3 is formed through a window provided in an oxidized film 5 on the P layer side 1a (regarded as the rear) of an Si substrate 1 with, for instance, a P-N junction formed in it. An metal electrode 4 consisting of three layers, namely, a Cr layer 4a, an Ni layer 4b and an Ag layer 4c is provided on an N layer side (the face). When elements thus having electrodes separately showing their face and rear are horizontally placed on a stand, an electromagnet is brought close to the element from above to attract elements supplied with magnetic electrodes 4 on the rear surfaces. Those which have not been attracted by the electromagnet are collectively turned inside out. After this, elements attracted by the electromagnet are sent back to the stand by reducing excitation current to 0, so that work of aligning elements separately showing their face and rear can be made with high efficiency.
