Filed: 1985-08-20
Abstract: PURPOSE:To form an SiO2 film having no defect on the surface of a metallic silicide by elevating the temperature of the silicide in an inert-gas atmosphere, changing over the inert-gas atmosphere into an oxidizing atmosphere and oxidizing the silicide when the temperature of the silicide reaches a fixed temperature, changing over the oxidizing atmosphere into the inert-gas atmosphere again and lowering the temperature of the silicide. CONSTITUTION:A wafer in which a poly Si layer 17 and a metallic silicide layer 18 are laminated on a substrate 11 is preheated, and the wafer is heated for a fixed time in an inert-gas atmosphere at a temperature lower than an oxidizing temperature and the temperature of the wafer is elevated. When the temperature of the wafer reaches the oxidizing temperature, the inert-gas atmospheres is changed over to an oxygen atmosphere, and the wafer is oxidized for a predetermined time. The oxygen atmosphere is changed over to the inert- gas atmosphere again, and the wafer is cooled slowly. Accordingly, oxidation is started after a point of time when Si in sufficient quantity diffuses in the inert-gas atmosphere, thus coating the wafer with an SiO2 film 20 having no defect.

Title: Rotary type elastic joint
Inventor: FURANTSU YOZEFU BORUFU
IPC: F16D3/50
Filed: 1983-09-30
Abstract: A rotationally elastic coupling with two half-couplings can be twisted relative to one another, these half-couplings being connected with one another so as to transmit forces by means of a sprung intermediate link and by means of a movement-converting intermediate link which converts a rotation into a translational movement or, vice versa, a translational movement into a rotation. At least one sheet metal support is provided which is in contact at a radially outward position with one of the sprung intermediate links which in turn is supported rotationally solidly and frictionally at a radially inward position with one of the two half-couplings. The sheet metal support is subjected to forces directly or by means of a coupling element of the movement converting intermediate link, in particular an eccentric or a crank, this movement converting intermediate link being rotationally and rotationally solidly connected to the other half-coupling. Using such a coupling, practically linear and soft spring characteristics can be produced for high torques over twist angle ranges of far beyond 30 DEG .

Title: Multi-size bus connection system for packet switching computer system
Inventor: NISHTALA SATYANARAYANA
IPC: G06F13/36
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To fast transfer the data by using a subsystem of masters which detects the bus width of slave devices and a controller which transfers the data at a speed suitable to the bus width. SOLUTION: The masters M1 to M3, the memories Mem1 to Mem2 and the slave devices S1 to S2 are connected to each other via a system controller SC 75. The SC 75 receives a data transfer request from a master and detects the bus width of a function unit whose address is designated. If the bus width of the master is equal to that of the function unit, the 1:1 data are transferred to the function unit from a master bus. If the bus width of the function unit is smaller than that of the master, a packet buffer is added and the 1:1 data are transferred between the master bus and the packet buffer. If the bus width of the function unit is larger than that of the master, the SC 75 transfers the 1:N data to the function unit from the master bus. Thus, the data can be transferred from every master at a higher speed.

Abstract: PROBLEM TO BE SOLVED: To prevent telephone call halfway abandonment with a caller in a situation that prevents immediate response, etc., and to surely perform telephone call by starting actual telephone call with the caller according to another operation of a portable terminal operator after notifying the caller that there is intention to answer through a prescribed operation upon receiving the call. SOLUTION: If a portable terminal operator recognizes an incoming call through a speaker 5, etc., when the operator is at a place preventing the operator from immediately performing speech communication, the portable terminal operator performs a preliminarily defined operation. A controller 1 detects the operation, stops incoming tone and responds to an incoming call. In such a case, the controller 1 connects only a voice guiding means 4 to a telephone network side. Next, the controller 1 transmits a message which is preliminarily recorded on the means 4 and indicates that there is intention to answer the incoming call to the telephone network side.  The portable terminal operator performs a prescribed operation when the operator arrives at a place where speech communication is available and the controller 1 switches the connection with the telephone network side from the means 4 to a microphone 6 and connects the speaker 5 at the same time.
