Abstract: PURPOSE:To stabilize the electrical characteristics at the boundary between an electrode and an insulating film by a method wherein a film of oxide of metal whose nitride is a conductor is used as the insulating film and the insulating film is nitrided to form the electrode composed of a metal nitride film. CONSTITUTION:A film 1 of oxide (for instance TiO2 or Ta2O5) of metal (for instance Ti or Ta) whose nitride is conductor is formed on a silicon substrate 4. The oxide film 1 is nitrided to form a film 2 of conductive metal nitride such as TiN or TaN and the nitride film 2 is used as an electrode. As the electrode 2 is formed by nitriding the insulating film 1, the electrical characteristics at the boundary between the insulating film 1 and the electrode 2 formed on the insulating film 1 can be stabilized.

Abstract: PURPOSE:To facilitate the adjustment of an offsetting quantity by individually detecting the offsetting of a speed detecting circuit and a command circuit, adjusting it individually and detecting the offsetting at the time of the input of an adjusting signal. CONSTITUTION:A first detector 7 keeps the value of a speed command R at the time of inputting an adjusting signal ADJ and sends an offset signal OR. A first adjuster 8 subtracts the signal OR from the command R, a second detector 9 keeps the value of a speed signal V at the time of inputting the signal ADJ and sends an offset signal Ov. A second adjuster 10 subtracts the signal Ov from the signal V. When the signal ADJ is inputted when a handle operation quantity H is zero and an antenna 1 is stopped, OR=Ro, Oo=Vo, Ro=0o Rc= R-OR=0 is obtained and at the time of a speed true value VT detected by an antenna, V=VT+Vc, Vc=V-Ov=VT is obtained. At the time of an output deviation E=Rc-Vc=Vc of an error computing element 5 and Vc=0, a motor is stopped by Eo=0. A person may input the signal ADJ only.

Title: Laser scanner
Inventor: SATO SHUICHI
IPC: G06K7/10
Filed: 1994-06-28
Abstract: PURPOSE:To vary the scanning angle of laser light corresponding to a distance to a reading object such as a bar code in the case of scanning that reading object with the laser light. CONSTITUTION:When a trigger switch 3 is manipulated and the laser light emitted from a laser light emitting part 4 is reflected back to the bar code, a reflected laser light photodetecting part 7 detects the received light intensity of that reflected light. Based on this received light intensity, a CPU 1 retrieves a correspondence table 10, reads out the manipulating angle corresponding to the received light intensity and sets it in a scanning angle setting amplifier 5. Thus, the shaking angle of a scan mirror provided inside a laser light scanning part 6 is controlled.

Abstract: PURPOSE:To enhance the machining accuracy of an infinitesimal pattern by employing an exposure mask having a pattern increased in width than the width of a mask pattern of the part corresponding to the recess (projection) of the surface of a substrate. CONSTITUTION:A resist is coated on a substrate having a recess or projection, the surface is flattened, is then exposed, an exposure mask 100 formed thinly (or thickly) as compared with the other part on the mask pattern 10 of the part 8 corresponding to the recess (or projection) of the substrate in case of the exposure. In this manner, since the insufficient exposure of excessive exposure caused by the difference of the thickness of the resist film corresponding to the unevenness of the substrate can be corrected thereby, an infinitesimal wiring pattern can be accurately formed.

Title: Speed change operating device for traveling transmission device
Inventor: SHIGEMATSU KENJI
IPC: B60W10/10
Filed: 1993-07-07
Abstract: PURPOSE:To surely stop traveling in a neutral N position, even when a reverse driving force works on a traveling shaft side on a slanting road or a slanting ground, by interlock a gear shift lever and a traveling clutch so that the traveling clutch is cut off on the basis of neutral N position operation of the gear shift lever. CONSTITUTION:When a gear shift lever is operated so as to be set in a neutral N position, speed change transmission of a continuously variable speed change belt transmission system B is with transmission of an epicyclic gear transmission system A, and transmission of an output traveling shaft 7 is stopped. Synchronously, a traveling clutch 40 is disconnected. In other words, when a vehicle is on a downward path or when an engine brake is operated, the revolution of an epicyclic gear 20 to a carrier 14 is restricted and internal braking is carried out because a speed change gear 22 and the carrier 14 are reversely driven from the traveling shaft 7 side. Especially, when the traveling clutch 40 for an input pulley 17 by a belt 39 from an engine E is disconnected and an input shaft 1 is not operated, a sun gear 3 side is not reversely driven from the carrier 14, as the continuously variable transmission belt 13 is not rotated.

Abstract: PURPOSE:To obtain an extremely fine Al pattern by a method wherein comprises applying an Al layer on a semiconductor substrate, covering said layer with a mask mutually complementing a specified electrode pattern, converting the Al surface exposed to an Al2O3 film, and dry etching the Al layer with said film as mask. CONSTITUTION:An Al layer 2 is applied on a semiconductor substrate 1 to make an electrode pattern afterward and provided thereon with a mask 3 mutually complementing a desired electrode pattern. An electrolyte liquid of ammonium boronate or the like is used to convert to an Al2O3 film 4 only the surface layer section of the layer 2 exposed into an opening of the mask 3 by positive oxidation. Then, the mask 3 is removed. Subsquently, with the film 4 as mask, a plasmaetching is made to remove the layer 2 not covered with the film 4 leaving a desired Al wiring 2' only under the film 4. Thereafter, while protection is provided between the wiring  2' with a resist layer 5, fluoric acid is used to remove the film 4 as unnecessary. In this manner, it is possible to obtain an Al pattern with a high reproducibility at a thickness of 2-3mum or less.

Title: Starter built-in type high pressure sodium lamp
Inventor: GION HIROSHI
IPC: H01J61/54
Filed: 1984-08-10
Abstract: PURPOSE:To quickly stop the operation of a starter when the rare gas for start flows inside an outer tube from a luminous tube, by generating glow discharge between a heat response switch and the induction section of a conductive body that is set to the potential reverse to the said switch and keeping the heat response switch to an open path state by using the heat. CONSTITUTION:A second heat response switch 10 made of a bimetal switch is connected to a starter 7 in series and mounted at a near place where conductive wires 3 and 4 are led out from stem glass 2. When the rare gas for start flows from a luminous tube 1 to the inside of an outer bulb 5, glow discharge is generated by the flowing rare gas between a second heat response switch 10 and a conductive wire 4 that is set to the reverse potential at lamp start. The second heat response switch 10 is opened by the heat due to this discharge and is kept in the open status. Consequently, voltage is not applied to the starter. As a result, subsequently the starter 7 is prevented from repeating the operation and the pulse voltage can be prevented from continuing being generated.

Title: Timer circuit
Inventor: AOYAMA AKIO
IPC: G06F1/14
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To detect phases with plural captures in plural timers by providing a first control means which simultaneously starts counting at least more than two counters in the plural timers. SOLUTION: The input waveforms of a clock a5 and a clock b15 are set to be equal. That a selector 32 selects STRa4 is set in SSR 31 and therefore the counter b12 refers to STRa4 as an operation content. The counter a2 and the counter b12 simultaneously start operations by setting STRa4 so that the operation is permitted. Thus, the phases of the pulses inputted to A16 and B6 are obtained by calculating a difference between the value of the counter n2, which the capture a3 takes in with the rise of the pulse inputted from A6 that desires to obtain the phase, and the value of the counter b12, which the capture b31 takes in with the rise of the pulse inputted from reference B16 for obtaining the phase.
