IPC: B21B37/00
Filed: 1983-12-27
Abstract: PURPOSE:To improve the accuracy and yield of a rolling material by adjusting the angle of the taper surface of a work roll having a shape tapered toward its end. CONSTITUTION:The outer peripheral surface of a sleeve end-part is formed into a shape tapered toward the side of a roll chock 12, and a ring spacer 20 is fitted freely movably in the axial direction in between an inner peripheral taper surface and a stepped part 19 of roll axis. A space surrounded by the sleeve end- part 18, the stepped part 19, and a seal ring 26 is formed into the 1st oil chamber 29 and the 2nd oil chamber 30 in an oil sealed state. The spacer 20 is moved to be in a loose fitting state when a pressurized oil is fed to the chamber 29, and the spacer 20 is moved to be in an engaging state when the oil is fed to the chamber 30. By setting the spacer 20 to a prescribed state, the angle theta of the taper surface of sleeve end-part 18 is changed to change a roll profile. In this way, the crown of the end part of a rolling material is controlled to an optimum state, and the accuracy and yield of the material are improved.

Title: Heater driving circuit
Inventor: ONO KAZUSHIGE
IPC: F01N3/02
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a heater driving circuit capable of properly controlling a current by using an FET on the high pressure side of a heater. SOLUTION: A constant voltage output part 10 F generates constant potential for a potential reference point terminal TE connected between a source of an FET and a heater. A control part 10 H impresses potential generated at the constant voltage output part 10 F on gates of FET 1 to FET 4. Therefore, also when the FET 1 to FET 4 are turned ON and potential on the side of the source becomes almost equal to potential of a power source, the FET can be properly controlled because potential higher than potential on the side of the source (potential of a potential reference point) is generated by the constant voltage output part 10 F.

Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To awaken a person silently even when a pointed article is searched while preventing a switch from being missed by providing a switch which can be pushed only with a pointed article and a temporary stop switch. SOLUTION: A switch A2 is a momentary push button switch for interrupting a bell momentarily. A switch B3 is an alternating push button switch, secured in a clock, which can not be pushed with a finger but can be pushed by means of a pointed article 5, e.g. a pencil, to interrupt the bell. The switch A2 is located at such position as it is not pushed easily even when the clock is tilted and has such resiliency as the finger is sprung back when a person sleeps while pushing the switch A2 with a hand. Since a person must wake up and leave the bed in order to search a pointed article 5 for pushing the switch B3, the person can wake up surely. When a person searches a pointed article 5 while pushing the switch A2, the person can wake up silently and comfortably.

Title: Semiconductor laser device
Inventor: KONNO NOBUAKI
IPC: H01S5/00
Filed: 1986-10-22
Abstract: PURPOSE:To lessen leakage current from booth clad layers holding an active layer between them as soon as possible by a method wherein a high-resistance semiconductor layer is formed on a high-resistance substrate and after a striped ridge part is formed thereon, a double hetero structure including the active layer is grown in such a way as to leave the form of the ridge. CONSTITUTION:A high-resistance AlGaAs layer 12 is formed on a high- resistance GaAs substrate 11 and a ridge part is formed on this high-resistance AlGaAs layer by etching, for example. As the layer thickness of an optical guide layer 13 is thin, the current path in this part is narrow and the leakage current is reduced. As the specific resistivity of an N-type AlGaAs layer grown on the slant face of the ridge part becomes higher by about one digit compared with that of an N-type AlGaAs layer grown on the flat part, the resistance of a clad layer 15 is increased here and the leakage current is similarly reduced. Moreover, as a high-resistance AlGaAs layer is used as the clad layer 12, no current flows to this part. As a result, a TJS laser of extremely low leakage current can be realized.

Filed: 1984-11-29
Abstract: PURPOSE:To produce the hybrid IC of high quality from which the failure of outer lead adhesion is eliminated, by a method wherein organic residues on a resistor pattern and a titanium protection mask are removed by previous treatment with ultraviolet rays, and titanium metal is removed by treatment with sulfuric acid at required temperature. CONSTITUTION:A tantalic acid thin film 2 is formed on an insulation substrate 1, and a positive photo resist 3 is applied over the surface, exposed, and developed into a desired photo resist pattern. Next, the substrate 1 is anodically oxidized in a solution of citric acid, thus forming an etching stop layer 4. The desired resistor pattern and the titanium protection mask pattern are formed by depositing a titanium metallic thin film 6 on the substrate. Then, the organic residues on surfaces are decomposed away by irradiation with ultraviolet rays 7. This manner enables the titanium protection mask with titanium oxide 8 produced on the surface after heat treatment to be removed in sulfuric acid at required temperature. An anode oxide film 9 is formed, and a dichromium alloy 10, palladium 11, and an Au layer 12 are deposited over the whole substrate; then, a circuit network including the capacitor and the resistor is obtained by photo resist and etching treatments.
