Title: Production of integrated circuit
Inventor: HIRAGA NORIAKI
IPC: H01L21/3205
Filed: 1984-04-26
Abstract: PURPOSE:To prevent a wire from being disconnected by difference in level, by depositing a quantum-beam-sensitive resist layer so as to contain an aperture of an insulation layer, depositing a first metallic layer after selectively removing the resist layer only in the region corresponding to the aperture and depositing a second metallic layer after melting and removing the resist layer. CONSTITUTION:A connecting hole 5 is formed in an insulation film 3 of an MOS semiconductor element so as to pass through the same and to reach a poly-Si layer 4 and a diffusion layer 2. The film 3 is then covered with a quantum-beam-sensitive resist 6. Quantum beams are selectively applied to develop the resist so that the resist 6 corresponding to the hole 5 is removed and the resist 6' is formed. After the ordinary development, the resist is further developed so as to remove any residual thin film of the resist on the bottom face 5a of the hole. When a first metallic layer 7 is provided thereon, the hole 5 is filled with the metal 7'. The resist 6' is melted to remove, and a second metallic layer 8 is deposited on the surface which has been flattened. According to this method,the wire is completely prevented from being disconnected by difference in level.

Title: Power steering device of integral type
Inventor: SUZUKI KATSUHIRO
IPC: F16H55/17
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To ensure a stable steering at the time of high speed forward operation by providing a projection at contact parts of both side surfaces of rack groove meshing with a sector gear tooth at the time of neutral state. SOLUTION: On both side surfaces of one of rack grooves 18a meshing with a sector gear 19 at the time of neutral state, a spherical projection 23 is formed. The adjustment is made so that the projection 23 is brought into contact with the gear 19 at the time of neutral state by an adjuster bolt. Backlash between the projection 23 of the rack groove 18a and the gear 19 becomes zero (0) since the projection 23 and the gear 19 are thus in contact with each other at the time of neutral state. Accordingly, a steering wheel does not shake and the stability of the steering is improved.

IPC: B05C17/10
Filed: 1981-06-02
Abstract: PURPOSE: To facilitate the control of the amount of an adhesive, to make the amount of the adhesive to be applied ununiform and to unnecessitate repolishing notches, by forming small-width strip-shaped notches at the lower side of a spatula for spreading the adhesive to a carpet, and attaching an adjusting plate, to control the height of the notches, to the lower side.  
     CONSTITUTION: Numerous small-width strip-shaped notches 3 are formed at the lower side of a spreading spatula made of nearly-square stainless steel sheet 2, and an adjusting plate 6 is attached to the lower side with a double-coated adhesive tape or the like. Owing to this constitution, the position of the adjusting plate 6 is controlled in a manner such that a required amount of adhesive is applied. A handle 4 is formed at the upper part of the spreading spatula 2. Accordingly, the applied amount can be easily controlled by controlling the position of the adjusting plate 6. Since the notchs are strip-shaped, the adhesive- applied width is made constant at all times. Even when the notches are worn away, the adhesive-applied amount is made constant and uniform at all times, without necessity of repolishing the notches.

Title: Exposure system
Inventor: HIRASAWA KEN
IPC: H04N1/23
Filed: 1988-04-08
Abstract: PURPOSE:To obtain an excellent image which is reduced in color shifting through easy operation by adjusting the irradiation position of one of a couple of exposure beams. CONSTITUTION:The position shift at the time of the movement of a photosensitive body 38 has a specific period, which is considered to set the gap X between the two light beams 33 and 34 projected on the photosensitive body 28 according to the variation period interval (x). This relation satisfies an expression I when (m) is an integer. Namely, the irradiation interval between the couple of light beams 33 and 44 is set to a distance which is almost an integral multiple of the periodic position shift in the moving direction of the photosensitive body 38. The interval X of one light beam to the other light beam which is to be adjusted is ideally mx in the expression I, but an excellent result is obtained actually within the range shown by the inequality. Consequently, the speed variation of the photosensitive body 38 itself is permitted and color shifting is reduced.
Patent JP-S60249904-A (JP)
Title: Decorative clasp
Inventor: JIIN BIO
IPC: A44C11/02
Filed: 1985-04-20
Abstract: A clasp with an interchangeable ornament includes a generally solid male clasp piece which is split longitudinally in a manner that it is transversely resilient, like a clip. A hollow female clasp piece has an insertion opening and an inwardly indented shoulder or lip at the insertion opening. When the male clasp piece is inserted into the female piece the shoulder of the female piece locks into a groove formed in the male clasp piece. Longitudinally extending slits in the peripheral wall of the female piece makes it transversely elastic and enables it to tightly hold an interchangeable ornamental sleeve that is fitted over the female piece. The ornamental sleeve in turn prevents the slit peripheral wall of the female piece from separating and assures that the inwardly indented shoulder remains locked in the groove of the male piece. Therefore, the male clasp part can not be a pulled out, except by squeezing the male piece to reduce its transverse cross-section to be smaller than the cross-section of the female piece.

Title: Combustion device
Inventor: NAGAOKA YUKIO
IPC: F23C6/00
Filed: 1986-04-14
Abstract: PURPOSE:To increase a variable range of combustion amount and improve a reliability in operation without having any movable part at a hot temperature part by a method wherein a rate of amount of air to be supplied to an air nozzle for shielding mixed gas flow with air and a fuel and air supplying part is varied. CONSTITUTION:In order to decrease a combustion amount, an electromagnet 33 of a changing-over means 39 is energized, a part of an amount of air to be supplied by an air supplying means 15 is sent to an air and fuel supplying means 14 through a bypass hole 31c and at the same time an air volume of 2-5 times of the former air volume is injected from an air nozzle 27, resulting in that a returning flow from the air nozzle 27 becomes an air curtain to cover the mixed gas flow and prevents the mixed gas from passing through a second communication passage 24. The mixed gas is enclosed by this returning flow and supplied only to the first communication passage 23 and then ignited only at a flame hole body 21a. That is, a flow of mixed fuel and air is controlled by the gas flow and the combustion portion of it is changed over to improve a poor operation caused by a thermal strain, a durability and a heat-resistant characteristic.
