Title: Dry etching
Inventor: SATO JUNICHI
IPC: H01L21/3065
Filed: 1991-03-19
Abstract: PURPOSE:To prevent deterioration an anisotropic shape at the time of overetching of a silicon group material layer and an Al group material layer and offer de-fluorocarbon measures and de-BCl3 measures. CONSTITUTION:When etching of an polyside film 5 is performed by using Si2S2F4 (tetrafluorocyclodisilathiane), a gate electrode 5a having an anisotropic shape is formed while a sidewall protective film 7 consisting of S, Si is formed on a pattern sidewall part. At the time of overetching, a silicon group radical dissociated and generated from Si2S2F4 catches surplus F* so that anisotropy is not reduced. Further, S2F2 may be used up to just etching while using Si2S2F4 only at the time overetching. When Si2S2Cl4 (tetrachlorocyclodisilathiane) is used for etching of an Al group material layer, the same effect can be obtained.

Abstract: PURPOSE:To prevent generation of a crack or breaking due to thermal influence or mechanical shock, by a method wherein a metallic cylindrical body and a ceramic lining layer coating its circumferential surface are joined to each other through a intermediate layer comprised of a viscoelastic body. CONSTITUTION:An intermediate layer 20 comprised of a viscoelastic body is formed on a interface between a metallic cylindrical body 10 and ceramic lining layer 30. When this composite member is made, for example, into a rolling belly part, shrink fit of a roll shaft 50 is performed within its hollow hole and fitted to the same through welding, the composite member can be made into a roll to be used for a copper foil manufacturing line. For example, natural rubber, synthetic rubber and synthetic resin are mentioned as the viscoelastic body forming the intermediate layer 20. The intermediate layer 20 absorbs and mitigates thermal stress generated due to a difference between a thermal expansion quantity of the metallic cylindrical body 10 and that of the ceramic lining layer 30. A thickness of the layer is made at least 0.1mm to reveal its function sufficiently. With the above-mentioned constitution, effects such as extension of the life and mitigation in maintenance can be obtained.

Filed: 1981-05-30
Abstract: PURPOSE:To improve the efficiency of data transfer by discriminating interlock transfer or split one with a requesting device according to the response of the opposite device at the time of requesting input in input transfer. CONSTITUTION:Response status signals BSSTSA-00, and BSSTSB-00 from the opposite device that has received a request for data transfer are decoded by a decoder 13, and in the case of split transfer, a signal BSSACK+10 goes to a logic value 1.

The signal BSSACK+10 is inputted to an NAND gate 20, after reversed, goes to MYBSYR-00 through an AND gate 14 and resets an FF9. Therefore, the signal MYBUSY+00 annihilates and bus occupation display signal BSBUSY-00, returns to a logic value 0, which releases occupation of the bus. On the other hand, the signal BSIACK+00 is inputted to an FF22, and sets a signal INTLOK+00, and the signal BSBUSY-00 holds the logic 1 which continues to occupy th bus.

Title: Connection of hybrid integrated circuit

IPC: H05K3/34
Filed: 1989-03-31
Abstract: PURPOSE:To improve heat conductivity and to suppress a coefficient of thermal expansion so as to prevent peeling of a substrate and of a conductor circuit pattern by, after soldering and connecting a lead frame on the substrate, using a resin including a great amount of aluminum oxide as a resin for fixation. CONSTITUTION:Into a ceramic substrate 1 and into a mounting land 2 composed of a thick film material such as a silver palladium provided on the surface thereof, a lead frame 3 that is composed of a phosphor bronze and so on is inserted in such a way it is sandwiched between them, for the mounting with an outer circuit, and is connected by a eutectic crystal solder 4. A resin for fixation 5 of an epoxy resin including aluminium oxide or of a polyimide resin is applied so as to cover the region by which the entire part for solder-mounting is coated. For the aluminium oxide to be added to the resin, as the value of high ratio is effective in order to suppress heat conductivity and thermal expansion, a weight ratio of 50% to 80% is desired. Since the thermal diffusion effect due to high heat conductivity and the generation of distortion due to low coefficient of thermal expansion rarely occur during the increase of temperature in soldering on the outer substrate, whereby damage to the lead frame connection part is eliminated.

IPC: H02P8/28
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To protect overheating by stopping power feed when the period interval of a drive pulse reaches fixed time or longer when a stepping motor is driven. SOLUTION: A drive pulse circuit 4 does not generate output when a stepping motor drive circuit 3 receives a pulse from a control circuit 1, starts supplying a drive pulse to a stepping motor 6, at the same time a drive pulse is received, and a period interval is a pulse within time determined by a time constant that a drive pulse-monitoring circuit 4 has. Then, when the period interval of the drive pulse reaches a time constant or longer, or when the drive pulse stops while a power feed circuit 5 is closed, output is automatically generated as soon as the period interval of the drive pulse exceeds the time constant for controlling the power feed circuit 5, a circuit is opened to stop the supply of power from the stepping motor drive circuit 3 to the stepping motor 6, thus preventing the stepping motor from overheating.

Title: Synchronizing signal generator for disk
Inventor: TAMARU NAOYUKI
IPC: G11B20/14
Filed: 1988-04-04
Abstract: PURPOSE:To increase the margin of access to a disk and to improve the reliability of synchronization control by interpolating a delay pulse output signal in the presence of dropout so as to obtain a synchronizing signal. CONSTITUTION:After a recovery signal of a synchronizing signal by a read recovery signal is converted into a pulsizing signal, the result is retarded by a delay means for a prescribed time only and supplied to a dropout detection means. When the dropout detection means discriminates a dropout based on a pulsizing signal, an interpolation means compensates the delayed pulse output signal by using an interpolation supply signal to output the synchronizing signal for desired disk control. Thus, even in the presence of a dropout, the synchronizing signal for controlling the desired disk is obtained and the operation of the circuit utilizing the synchronizing signal is ensured.
