Title: Pasting apparatus of semiconductor substrates
Inventor: KAWASHIMA HIDEAKI
IPC: H01L21/02
Filed: 1992-01-10
Abstract: PURPOSE:To eliminate that moisture, dust particles and the like adhere between two semiconductor substrates and to prevent air bubbles from being produced between them by a method wherein, in an apparatus used to manufacture a multilayer device which has pasted the two semiconductor substrates, a container which houses the apparatus is installed and the inside of the container is kept in a vacuum state. CONSTITUTION:Semiconductor substrates 1, 2 are aligned; after that, pasting members 11, 12 are moved and brought close by drive means 21, 22. When centers of the semiconductor substrates 1, 2 come into contact with each other, the movement of the pasting members 11, 12 is stopped. The pasting members 11, 12 are heated by means of heaters 19, 20. When they reach a prescribed temperature, they are restored and deformed in such a way that pasting faces 13, 14 become flat faces, and they are brought into close contact. Such operations are performed inside a chamber 3 which is always in a vacuum state by using a vacuum pump 4. Consequently, it is possible to prevent that air bubbles are produced between the semiconductor substrates 1, 2 and that moisture and dust particles adhere, and the semiconductor substrates can be pasted with extremely good close adhesion.

Title: Calculation of h-factor of continuous digester
Inventor: NISHIMURA ATSUSHI
IPC: D21C7/12
Filed: 1990-01-31
Abstract: PURPOSE:To carry out an efficient operation by dividing a digester into plural stages from the top part to the bottom part and considering the difference of the reaction rate constant depending on weighting of H-factor to the respective reaction phases and on the difference in the activation energy based on the quality of a material. CONSTITUTION:A continuous digester is divided vertically into plural stages, (ST0, ST1,..., STn) from the top part to the bottom part and the boundary between penetration stage and digestion stage is estimated. For the respective stages, an H-factor is calculated while varying the value of activation energy making the standard value thereof the mean value and an estimated kappa-number is calculated so that a kappa-number dispersion correlation may be obtained. A point showing the highest value in the dispersion correlation is used as a parameter for H-factor calculation and the activation energy based on the quality of the pulp is calculated thereby.

Title: Manufacture of ferromagnetic metal powder
Inventor: TAGAWA KIMITERU
IPC: H01F1/06
Filed: 1991-02-15
Abstract: PURPOSE:To obtain ferromagnetic metal powder for magnetic recording use which has high saturation magnetization and oxidation stability. CONSTITUTION:In addition to Si, Al, etc., which have been conventionally used as preventing components of sintering, transition metal elements like Cr, Mn, etc., are precipitated by using alkali carbonate, and stuck on the surface of oxy hydroxide or oxide whose main component is iron. By this method, a lot of metal elements can be uniformly precipitated and stuck. In a process wherein ferromagnetic metal powder is formed by using the above material, the purpose can be attained by the effect of interaction (formation of alloy, ferrite, etc., on the surface) between iron as the main component and the metal elements which are precipitated and stuck.

Filed: 1986-02-05
Abstract: PURPOSE:To allow one communication controller to execute data transmission in addition to calling or incoming even when transmission procedures are changed depending on, e.g., outgoing/incoming or data transmission by providing plural control tables. CONSTITUTION:When the connection of line exchange is designated by a main interface at the initial setting from a central processing unit 3, a microprogram 12 of a communication controller 1 selects an outgoing/incoming control table 11 as a control table. When an outgoing or an incoming command is received from the central processing unit 3, the operation according to the control table is performed. When the outgoing or incoming is finished normally, the communicable state is reached and in this case, the microprogram 12 selects a transmission control table 10 as the control table. When the reception or transmission command is received from the central processing unit 3, data is sent according to the control table. When a command disconnecting the connection with a line exchange network is received from the central processing unit 3, the restoration is operated and outgoing/incoming control table 11 is selected as the control table.

Title: Driving method for solid-state image pickup element
Inventor: YONEDA MASATO
IPC: H04N5/335
Filed: 1982-02-15
Abstract: PURPOSE:To control signal charge lower than a line capacity without providing excess charge production unit by applying read-out pulse application period pulse to a photoelectric film which is coupled to a diode when the charge is read out from a charge storage diode to a transfer line. CONSTITUTION:A signal charge 19 produced at a photoelectric film 17 at the time t0 is stored in a diode 16, read out at the time t1, pulses are applied to transfer gates 15, 14, a voltage well is decreased, and the charge 10 is stored. A pulse is applied to an electrode 18 on a photoelectric film 17 during t2 before the read pulse is removed to raise the voltage of the n<+> layer 16, thereby returning the excess charge 20 to the diode side. At this time the maximum transfer charge 21 remains under the transfer gate 14, and the charge which is limited to a value lower than the maximum transfer charge amount is read out for the t3. According to this method, excessive charge is swept out, the formation of the drain is made unnecessary, the manufacturing steps are simplified, the transfer line width can be expanded, thereby increasing the signal charge.

Title: Welding method for metal plate
Inventor: NISHIKATA MASAHARU
IPC: B23K20/10
Filed: 1986-02-04
Abstract: PURPOSE:To eliminate the dislocation of the relative position of a welding member each other by welding both metal plates after locating the 2nd metal plate in the external shape size almost equivalent to the hollow part having plural foot parts on the outer peripheral part to the inside of the hollow part formed on the 1st metal plate. CONSTITUTION:A hollow part 12 is formed on the welding place of the 1st metal plate 5 and the external shape size of the 2nd metal plate 6 is taken in the size nearly equivalent to the hollow part 12 and plural foot parts 11 are formed on the outer periphery. An ultrasonic vibration is given after impressing a pressure by abutting a tool 4 on the upper face of the 2nd metal plate 6 by locating the 2nd metal plate 6 inside the hollow part 12 of the 1st metal plate 5 on the above of an anvil 9. In this way a friction heat is generated on the abutting face of both metal plates 6 and 5 and both metal plates 5 and 6 are subjected to a solid phase junction by the atomic combination or the diffused junction among stoms. In this case the dislocation of the relative position can be restrained since the position of the foot part 11 is regulated inside the hollow part 12.

Title: Heating cooker
Inventor: WATANABE KENJI
IPC: H05B3/20
Filed: 1987-02-03
Abstract: PURPOSE:To improve a thermal efficiency, eliminate a disturbance of heating in a heated item and prevent an inside part of a heating chamber from being stained by a method wherein an upper surface of an inner wall of the heating chamber is formed with a first coating film of non-metallic material having a high heat-resistant and high radiation rate, and a right and left side and a bottom surface of an opening of an inner wall are formed with a second coating film having a high radiation rate without any adhesion. CONSTITUTION:As a heating operation is promoted and an upper surface heater 13 is heated, an upper wall 12a of the inner wall of a heating chamber 12 shows a hot temperature. However, since a first coating film 27 of non-metallic substance having a high heat-resistance and a high radiation rate is formed on the upper surface 12a of the heating chamber 12, a thermal dispersion is superior and a heating efficiency is high. In addition, since the upper surface 12a of the heating chamber 12 is kept at a high temperature, a stain such as oil splashed from a heated item 18 such as a food can be burnt out spontaneously during heating operation. Since both side surfaces 12b and 12c of the heating chamber 12 are formed with a second coating film 28 having no adhesion and having a high radiation rate including a compound of fluorine, the stain may not be adhered well and the stain may be removed off with a light wiping-off operation.
