Abstract: PURPOSE:To prevent the short-circuit of metal lines and thin the device by bonding one of the common leads on a plane whereupon a circuit is to be formed through an insulating member and electrically connecting the common lead with a semiconductor element by the metal line. CONSTITUTION:Shared leads 3a extend the vicinity of the edges of a semiconductor element 1 in parallel to the long side of the element. The leads 3a are bonded on the circuit forming plane 1a of the semiconductor element 1 through an insulating member 2 and signal leads 3b are arranged on the external side of the semiconductor element 1. Bonding pads 1Bp are provided along the outer edges of the common leads 3 on the circuit forming plane 1a of the semiconductor element 1. The bonding pad 1Bp, the common lead 3a and the signal lead 3b are electrically connected by a metal line 4. The two circuit forming planes 1a of the semiconductor elements 1 are laminated by facing each other and the leads 3 are bonded. Since the wire bonding of the signal lead 3b and the semiconductor element over the common lead 3a is not necessitated, short-circuit of the top and bottom metal lines 4 is prevented.

Title: Production of photomask
Inventor: KOIZUMI YASUHIRO
IPC: G03F1/40
Filed: 1987-01-26
Abstract: PURPOSE:To obtain a satisfactory photomask at a high yield by forming a thin carbon film by vapor deposition on a photomask substrate prior to formation of a chromium oxide film on said substrate. CONSTITUTION:Carbon receives the influence of heat and is easily diffused into the glass substrate 1 to have the high adhesiveness to the substrate when the thin carbon film 2 is formed by a vapor deposition method on the substrate 1. Vacuum deposition of high-purity chromium is executed under oxygen partial pressure to form the thin chromium oxide film 3 on the film 2 and the photomask film 4 is deposited on the film 3. A pattern is drawn thereon by electron beam scanning and is subjected to a development process. Since the film 2 has electrical conductivity, the charge of the thin film 3 formed thereon escapes to the side of the thin film 2 even if the pattern consisting of said thin film is electrified. The inter-pattern electrostatic breakdown by the concentration of the charge is thus prevented. The photomask having the high dimensional accuracy of the pattern is thereby formed at the high yield.

That is, a delay circuit 9 from which one output is taken out as the comb line filter output (c) by adding the input (a) in the adding resistance 4 and the other is taken out as the delay output (b) is obtained.

IPC: F01L1/34
Filed: 1992-01-29
Abstract: PURPOSE:To reduce torque fluctuation of a cam shaft in the variable valve device in an internal combustion engine so as to easily disassemble and assemble two parts discriminated from view of their functions. CONSTITUTION:A variable valve timing device(VVT) 1 comprises a phase conversion part 9 for converting rotational phase of a cam shaft 5 and a hydraulic driving part 10 for driving the phase conversion part 9. The phase conversion part 9 is provided rotatably in one body together with the cam shaft 5, and the casing 22 of the driving part 10 is provided on-rotatably on a cylinder head 3. The ring gear 13 of the phase conversion part 9 is connected to the operating rod 24 of the driving part 10 in such a way that a bearing 26 is fit in the sleeve 20 of the ring gear 13 to be prevented from slipping off by a cisclip 37. It is thus possible to reduce an inertia load applied on the cam shaft 5 at the time of rotation by only an amount due to the driving part 10. The cisclip 37 is operated from the outer circumferential side of the sleeve 20, and thereby, the sleeve 20 is disconnected and/or connected from/to the bearing 26.

Title: Vertical shaft type volute pump
Inventor: KOUDA MASAE
IPC: F04D13/00
Filed: 1981-02-04
Abstract: PURPOSE:To prevent occurrence of vibration and noises by a pump and to reduce the entire size of the pump, by connecting a suction pipe to a peripheral wall of a hollow cylindrical member, and connecting a discharge pipe to a volute chamber formed at the lower end portion of the hollow cylindrical member and incorporating therein an impeller. CONSTITUTION:Water supplied from a suction pipe 2 at an upper portion of a hollow cylindrical member 1 is drawn into an impeller 5 which is turned by a main shaft 8, converted into pressure energy in a volute chamber 4, and then carried above the floor via a discharge pipe 9. Since, with such an arrangement, water flows into the impeller 5 directly from the above in the manner of reducing the resistance of water flow, water is introduced into and discharged from the pump smoothly, so that production of noises and vibration by the pump can be prevented. Further, the entire size of the pump can be reduced by decreasing the distance between the suction pipe and a water drawing portion.

Title: Manufacture of sealed contact material
Inventor: YAMAMOTO KIYOSHI
IPC: C23C14/34
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a sealed contact material with prolonged contact life. SOLUTION: This manufacturing method is for manufacturing a sealed contact material having at least one coating layer on the surface of a contact substrate. The coating layer comprises at least one matrix element selected from Mo, Zr, Nb, Hf, Ta, and W and containing 0.5-50 atomic % of at least one addition element selected from Zn, Cd, Hg, Al, Ga, In, Tl, Ge, Sn, Pb, As, Sb, and Bi and is formed by sputtering method while controlling the temperature of the contact substrate at 190 deg.C or lower. Since the coating layer is formed on the contact substrate controlled to be at low temperature, no low melting point element-concentrated part and no part having improper composition ratio which inhibit opening and closing operation are formed in the coating layer.  Moreover, since the coating layer is formed by sputtering method, the coating layer is closely and firmly attached to the contact substrate. Consequently, opening and closing operation failure hardly occurs and a sealed contact material with a long contact life can be obtained.

Title: Manufacture of resonator of semiconductor laser
Inventor: UCHIDA MAMORU
IPC: H01S5/042
Filed: 1987-01-23
Abstract: PURPOSE:To upgrade an annealing effect of crystal damages done in a dry etching process, by etching a compound semiconductor crystal of double hetero structure under a high vacuum so as to form an etched mirror and in succession forming a dielectric film by coating and then annealing this film. CONSTITUTION:An electrode 105 is formed selectively on a laser wafer by means of an E gun, milling and the like. Next, while this electrode 105 is covered, an etching mask 106 is formed and edge formation is performed by reactive ion beam etching or the like. While a high vacuum is maintained in succession, a stable dielectric film 107 is formed on the etching edge by an E gun evaporator. Since the E gun is strong in directivity, it is excellent in controllability for film thickness and has an advantage that thin films on a front and a rear of a substrate can be formed independently. Next, the mask and the dielectric film on the electrode 105 are removed by reactive ion etching or the like. Thereafter, annealing is performed under an atmosphere of nitrogen and finally an electrode 108 is formed on the rear of the crystal.

Abstract: PURPOSE:To decrease the number of components and to detect the position of an objective without decreasing the quantity of incident luminous flux by processing a cut part formed in a turntable into a mirror surface and reflecting the marginal part of the incident luminous flux, and detecting the position of an objective from the output of a photodetector which photodetects the reflected light. CONSTITUTION:The turntable 31 which holds the objective 17 is provided with the cut part on its incidence side for the luminous flux incident on the objective 17 and the cut part is made into the mirror surface to form a mirror part 32. The marginal part of the luminous flux 16 incident on the objective 17 is reflected by the mirror part 32 and incident on a two-division photodetector 33 for objective position detection which has two photodetection surfaces 33a and 33b. Thus, the luminous flux which is eclipsed because of the effective incidence diameter of the objective, so the quantity of light incident on the objective is not reduced, no additional component is required, and the position of the objective is detected by the simple constitution.
