Filed: 1988-02-25
Abstract: PURPOSE:To easily make a scan over a wide area, to find the position of a sample, and to carry out unmanned operation, etc., by adding a system which drives the sample by a motor to the scanning tunnel microscope. CONSTITUTION:A driving part 1 has an X-driving and Y-driving piezoelectric element and a Z-driving piezoelectric element for making a tunnel current constant and drives and scans a probe 2 in an extremely small area. The sample 3 is fitted to a holder 5 and inserted into a vacuum chamber 6 from the flank. The holder 5 is driven by motors 9a and 9b in an X-axial and a Y-axial direction. While a fine movement piezoelectric element is stopped, the sample 3 is moved by the X-axial and Y-axial motors 9a and 9b to search a target area. Thus, the motors 9a and 9b are used for the driving, so this movement range is wide. Consequently, the wide area is scanned, the position of the sample 3 is found, and the unmanned operation, etc., is easily performed.

Filed: 1991-03-08
Abstract: PURPOSE:To defrost a heat exchanger and remove the constituent of smell existing in a refrigerator especially in the refrigerator provided with deodorizing function. CONSTITUTION:Smell in a refrigerator 7 is sucked usually by a fan through an air suction port 9 to adsorb the smell by a catalyst coating layer 3 and/or another catalyst coating layer 4 containing zeolite while cooling is effected by a heat exchanger 6. When frost is adhered to the heat exchanger 6 and a cooling capacity is dropped, a catalyst is activated by conducting electric current through a heat generating body 2 to decompose the small, adsorbed by the catalyst coating layer 3 and the catalyst coating layer 4, and eliminate the smell thereof. At the same time, frost, adhered to the heat exchanger 6, is removed by the ascending of heated air. Water drops will never be hitted against the heat generating body 2 by a water drop protecting plate 5. After the frost, adhered to the heat exchanger 6, is removed and the adsorbing capacity of the catalyst layer 3 and/or the catalyst layer 4 is restored again, the conduction of the electric current is stopped again to adsorb the constituents of smell. The adsorption of the smell and the decomposition of the smell are repeated alternately in such a manner.

Abstract: PURPOSE:To reduce a noise, to improve the reproducibility and to enhance the velocity of operation by forming a base and a collector layer out of the (AlGaIn)As mixed crystal comprising the composition which satisfies the predetermined relation with the InP forming an emitter layer. CONSTITUTION:On an N<+> type InP substrate 11, an N-type collector layer 12 of Al0.17Ga0.30In0.53As, a P-type base layer 13 of Al0.17Ga0.30In0.53As, and an N-type emitter layer 14 are laminated in order. As an emitter electrode 16, AuGe/Au is vapor-deposited on the upper surface followed by etching with the part which is to be an emitter left. AuZn is vapor-deposited on the exposed base layer 13 to form an base electrode 17 and further a collecter electrode 18 is formed by applying In on the back side of the substrate 11 to make it an alloy. Thus a hetero junction bipolar transistor is fabricated. Because the electron affinities of InP and Al0.17Ga0.30In0.53As are equal, there is no discontinuous part of spike form produced in the boundary region between the emitter layer 14 and the base layer 13 and the ideal hetero interface can be obtained.

Abstract: PURPOSE:To produce a liq. toner narrow in grain diameter distribution and good in monodispersive property by using an unthickened graft polymer insoluble in aliphatic hydrocarbon solvent as a fixing agent. CONSTITUTION:A polymer soluble in aliphatic hydrocarbons is bound to the surface of a monodisperse polymer fine grain obtained by soap-free emulsion polymerization. A monodisperse polymer fine grain of submicron order is generally obtained by so ap-free emulsion polymerization, and the fine grain is copolymerized with a water-soluble monomer having a functional group to form a polymer having a functional group only on the grain surface. The surface is treated with a silane coupling agent having a polymerization-active double bond with the hydroxyl group on the grain surface as a base to introduce a double bond into the grain surface. The treated grain and a monomer giving a polymer soluble in the aliphatic hydrocarbons are formed into a polymer, and the grain with the polymer grafted on the surface is obtained. Consequently, a liq. toner stably dispersed in the aliphatic hydrocarbons and giving a monodisperse system having a uniform grain diameter is produced.

Title: Control valve
Inventor: OOISHI SHIZUMARO
IPC: G05D16/14
Filed: 1991-02-15
Abstract: PURPOSE:To protect high differential pressure from being applied and to enable small operating power to operate a valve member by canceling a pressure difference between the primary side and the secondary side using the first and second pressure rooms. CONSTITUTION:When a valve member 6 is closed, liquid from inlet 2 flows in a control valve partly passes through labyrinth 11 and reaches the first pressure room 8, while the other part of the liquid passes through a through hole 20 and reaches the under room 19 of the lower piston 13. Accordingly, the load applied to valve member 6 in the closed valve direction based on the pressure difference between inlet side 2 and exhaust side 4 is canceled by an upward load applied to the lower piston 13, thus being reduced to small value. When the valve member 6 is opened a little by an operating rod 12, the lower end of piston 10 is still positioned in the cylindrical section of valve seat member 5, a quantity of flow that flows in the first pressure room 8 is as little as the quantity of flow that reaches passing through labyrinth 11, and hence the flow rate of liquid flowing down between valve seating section 7 and seal surface 9 becomes slow. Accordingly, no erosion damage is applied to both the valve setting section 7 and the seal section 9.
