Title: Manufacture of field-effect type semiconductor device
Inventor: SAMOTO NORIHIKO
IPC: H01L21/338
Filed: 1988-10-14
Abstract: PURPOSE:To reduce a source-gate capacity even when a gate electrode is situated close to a source electrode by a method wherein the gate electrode whose cross section is L-shaped is formed. CONSTITUTION:A source electrode 2 and a drain electrode 3 are formed on a semiconductor substrate 1; then, the substrate 1 is coated with a first resist 4; this resist is coated with a second resist 5 whose sensitivity is lower than that of the first resist 4; in addition, this resist is coated with a third resist 6 whose sensitivity is higher than that of the resists 4, 5; a pre-baking operation is executed. Then, the following are executed: an exposure operation 7 of a pattern corresponding to a gate length; an exposure operation 8 of a pattern corresponding to a size expanding a gate electrode to be L-shaped in such a way that the exposure operation 7 is included at an end part on the side of the source electrode 2. Then, a developing operation is executed; openings 9a, 9b, 9c are formed. During this process, the opening 9c becomes smaller than the opening 9a. Then, the exposed substrate is etched; a recessed opening 10 is formed; gate metals 11a, 11b are evaporated. Then, the resists 4, 5, 6 and the unnecessary metal 11a are removed; thereby, an asymmetrically recessed L-shaped electrode 11b is formed.

Title: Photo secondary cell
Inventor: KANBARA TERUHISA
IPC: H01M4/58
Filed: 1985-11-15
Abstract: PURPOSE:To increase the quantum efficiency of photo charging by employing a material mainly composed of ZrS2-x (0<x<0.5) as the positive electrode material of a cell. CONSTITUTION:A negative electrode mainly composed of metal copper, a Cu<+> ion conductive solid electrolyte and a positive electrode mainly composed of ZrS2-x (0<x<0.5) are laminated sequentially to enable charging by irradiating the positive electrode by means of the light. ZrS2 has a considerable energy gap between a valence electron band and a conductive band thereby the electronic conductivity is very low, thus generating a cause for lowering the quantum efficiency in the case of performing photo charging. Consequently, S is removed by predetermined quantity from the equivalent composition or ZrS2 to provide a local between the valence electron band and the conductive band to increase the electronic conductivity, thus improving the quantum efficiency of photo charging. Since S is rendered insufficient to the equivalent ratio, its isolation is almost eliminated.

Title: Catalyst for purifying exhaust gas
Inventor: OGAWA OSAMU
IPC: B01D53/81
Filed: 1994-10-21
Abstract: PURPOSE: To prevent the deterioration in NOx purification performance after Cong term duration by preventing the sulfur poisoning of a NOx absorbent while keeping initial NOx purifying rate. CONSTITUTION: This catalyst is made by carrying the NOx absorbent, selected from a Ti-Zr conjugate oxide, an alkali metal, an alkaline earth metal, a rare earth element, and a catalyst noble metal on an alumina carrier. The acidity of the alumina carrier itself is increased by carrying the Ti-Zr conjugate oxide and since it is considered that the adsorption of SOx to alumina is decreased with the increase of the acidity of the alumina carrier because of the acidity of SOx, the sulfur poisoning of the NOx absorbent due to the absorption of SOx is prevented.

Title: Thermal head
Inventor: MOTO YOICHI
IPC: B41J2/335
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent an adhesive from having uneven thickness by making the through hole of a heat plate in stripe shape elongating substantially in parallel with a heating element array except the region immediately under the heating element array while extending the oppo ntially in parallel with an heating element array 2 except the region immediately under the heating element array while extending the opposite end parts thereof to the outside region P of the heating element array. Consequently, the heat transmission rate from a head substrate 1 to the heat plate is substantially uniform mover the fixing region of the heating element array 2 and the surface temperature of the head substrate 1 does not fluctuate significantly even if a thermal head i.s operated repeatedly for a long time.  Since the head substrate 1 is bonded to the heat plate through an adhesive in the through hole 3a, the lower surface of the head substrate 1 can abut directly on the upper surface of the heat plate on the opposite sides of the heating element array 2 and a constant distance can be kept between the head substrate 1 and the heat site end parts to the outside region of the heating element array. SOLUTION: The through hole 3a of a heat plate is made in stripe shape elongating substa plate.

IPC: B29B7/66
Filed: 1989-10-03
Abstract: PURPOSE:To enable raking of rubber edges to parts near the centers of making rolls safely and easily by arranging two rubber-raking dishes in one-side end parts of the making rolls through mutually offsetting the dishes in the circumferential and axial directions of the making rolls, by biasing the dishes to the surfaces of the making rolls and by rotating them with a motor. CONSTITUTION:Against rubber edges 15, 16 cut from rubber sheets 9, 10 and stuck on the surfaces of making rolls 1, 3, two rubber-raking dishes 17-20 biased to the making rolls 1, 3 by elastic means are rotated on the basis of the action of rotation-driving means. Therefore, the rubber edges 15, 16 stuck especially to parts near the axial ends of the making rolls 1, 3 can be raked to parts near the centers of the making rolls 1, 3 smoothly enough and always surely. As a result, all rubber edges 15, 16 are suitably resupplied between stock guides 5, 6. Thus, all inconvenience caused by forming a bus-line for resupplying the rubber edges 15, 16 between the stock guides 5, 6 can be removed naturally and it is also possible to guarantee always sure raking of rubber edges.

Filed: 1995-10-04
Abstract: PURPOSE: To make it easy for a user to see relations between functions and pointers and to improve operability by a construction wherein small pointers indicating the functions are provided in proximity to external operating members related to the functions, apart from the central position. CONSTITUTION: In the case when a second stem 23 is set at an ordinary position, a chronographic mode is brought about and measurement is started and stopped every time when a switch 24 is pushed. After the start, a 1/5 CG hand 21 and a minute CG hand 31 are operated at intervals of 1/5 second and one minute respectively. When the stem 23 is set at the first-stage position, a timer mode is brought about, and when a switch 25 is pushed at the time of setting, the CG hand 21 indicating the set time is operated by one minute. Start and stop are executed by a switch 24. Every time when a switch 26 is pushed in the state wherein the stem 23 is set at the first-stage position, an AL minute hand 38 and an AL hour hand 39 are operated in minutes to set an alarm time. When the switch 26 is pushed continuously, the hands run continuously and the time can be thereby set in a short time. Since pointers indicating functions are disposed in proximity to switches for operating the functions, in this way, it is easy for a user to see relations between them.

Title: Tunnel support selection method
Inventor: SHINOHARA SHIGERU
IPC: E21D11/40
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To select appropriate supports immediately for a wall just after excavation by selecting supports to be installed at the excavated wall from among multiple kinds of supports on the basis of vibration occurring from the excavation of a tunnel excavator. SOLUTION: The coefficient of variation is computed from the vibration of an excavator with an accelerometer 5, an A/D converter 7 and a waveform processing section 8 while excavating a rock mass with a cutter head 1 and advancing the tunnel excavator. When the coefficient of variation is large, on the assumption that the rock mass has many cracks, strong supports are selected and the selected supports are installed on the excavated wall. When the coefficient of variation is small, on the assumption that the rock mass has a few cracks, no support or ring supports 21 are selected and the selected supports 21 are installed at the excavated wall except when no supports are used. Therefore, appropriate supports can be selected quickly without confirming the wall after excavation visually.
