Title: Shadow mask type color picture tube
Inventor: HIRAI RYOJI
IPC: H01J31/20
Filed: 1987-12-02
Abstract: PURPOSE:To make a face plate looks like flat, to improve the doming phenome non, and to increase the strength of a glass envelope, by forming the curvature of the long side periphery larger 10% or more than the curvature of the short side periphery. CONSTITUTION:The curvature of the long side periphery is formed larger 10% or more than the curvature of the short side periphery. Since the curvature of the long side periphery 17 is larger than that of the short side periphery 16 in such a way, a flat face plate panel is obtained without giving a large variation of the average curvature radius in the diagonal direction, by setting the curvature along the long side periphery 17 and the short axis 14 large, even though the curvature of the short side periphery 18 which contributes mostly to give a flat looking to the viewers is made small. Moreover, since the average curvature radius in the diagonal direction can be suppressed small, the deterioration of strength of a glass envelope 4 can be prevented.

Title: Alcohol engine
Inventor: HIKINO SEIJI
IPC: F02B23/10
Filed: 1988-11-30
Abstract: PURPOSE:To stabilize combustion and prolong the life of a spark plug by forming, in a combustion chamber, a peripheral wall face nearly orthogonal to the direction of combustion injection along the circumferential direction. CONSTITUTION:A top clearance of 2-5mm is taken when a piston 13 is at its top dead point, and a lip 20 is formed at the edge of the opening of a combustion chamber 15. In addition, a peripheral wall face 22 nearly orthogonal to the direction of fuel spray injected from an injector 16 is formed in the combustion chamber 15 along its circumferential direction. This arrangement enlarges the value of the top clearance and weakens squish to prevent an excessive mixing of alcohol fuel spray and air, which improves ignitability or ignitionability and prolongs the life of a spark plug 17. Furthermore, since the fuel injected from the injector 16 collides nearly at right angle to the peripheral wall face of the combustion chamber 15, the gasification of fuel is facilitated to stabilized combustion.

CONSTITUTION:A membranous electric heating body 2 is formed by printed- wiring on a base 1, a copying paper on which a toner is attached is inserted between a heater A and a roller B, and the toner is fused and fixed on the copying paper by the heat of the heater A. And the width w of the heating body 2 is limited in the scope 0.5 to 10mm. The side edge of the heating body 2 of the printed wiring has minute unevenness making the electric resistance uneven locally, and the electric resistance is increased as the width of the heating body 2 is made smaller. And at the recess where the width is less than 0.5mm, the temperature is increased abnormally. And when the width in made larger than 10mm, it is of no use to the heating since the effective length is the contact length W. Consequently, a local overheating is eliminated and the waste of power is excluded.

Abstract: PROBLEM TO BE SOLVED: To provide a laser printer which can easily perform highly precise printing at a high speed by making the spot diameter of the laser beam emitted from the printer variable while the light density of the laser beam spot is maintained at a prescribed value. SOLUTION: The laser beam 115 emitted from a semiconductor laser 114 is made incident to the polygon mirror 120 of a light deflector through a collimating lens 116, etc., and the mirror 120 reflects and deflects the beam 115 as the mirror 120 rotates. Then the laser beam is converged on a surface to be scanned coated with a photosensitive material 122 through a scanning lens system 121 and the surface is repeatedly scanned at the same speed. The current used for driving the laser 114 is divided into parts for a central stripe 128 and for both side stripes 129 and the intensity of the laser light is modulated with a signal from a control section.  When the three stripes of the semiconductor laser device 114 are oscillated at the same light intensity, the spot diameter of the laser beam 115 becomes about three times as large as that obtained when the central stripe is oscillated strongly and both side stripes are oscillated weakly.

Title: Wiring method of copper or copper alloy and structure thereof
Inventor: NUMATA ATSUSHI
IPC: H01L21/28
Filed: 1989-11-27
Abstract: PURPOSE:To improve the oxidation resistance of copper, and to form a copper wiring having high reliability by inactivating chemically active copper, extremely increasing crystal grain size as large as or larger than the wiring width of the copper wiring. CONSTITUTION:A copper film 1 is applied onto a substrate 3, crystal grain size is increased extremely, and the crystal grain size is made larger than the wiring width of a copper wiring. Consequently, crystal grain size is grown and a diffusion rate into the copper film 1 of oxygen is decreased in the active copper film 1, thus improving oxidation resistance. Since the copper film 1 is inactivated, a copper surface is not oxidized under the temperature at the time of applying, even if other metal or alloy is applied for the purpose of enhancing oxidation resistance subsequently. Likewise, stable copper nitride and copper fluoride can be formed because no copper oxide is formed on the copper surface even when nitriding treatment and fluorination treatment are executed. Accordingly, the reliability of the wiring can be improved.

Abstract: PURPOSE: To attain improvement in efficiency with a simple method by providing element to be operated by a feed mechanism for relaxing a thread from a shuttle for each cycle of the feed mechanism. CONSTITUTION: A feed dog 17 is provided with the element for relaxing the thread from the shuttle for each cycle of the feed mechanism, this element is composed of a U-shaped elastic steel wire 21, and the arm is bent at the rear end part thereof shown by 22 and housed in one part of the dog 17. Each arm of this U-shaped member passes through a hole in a supporting part 23, which can be slid at the vertical portion of the dog 17, and when moving the dog 17 upward for holding cloth to be sewn, each supporting part 23 deforms the steel wire 21 downward in contact with a needle plate 18 so that a tension can be exerted on a thread 8. When moving the dog 17 downward by the feed mechanism, the steel wire 21 is returned to the initial position and no tension is exerted on the lower thread 8 any more.  Therefore, the thread 8 is relaxed and the pulling of a lower thread into an object to be sewn is promoted by a pulling effect exerted by an upper thread 14 regardless of a sewing speed. The length of the thread to b relaxed for each cycle is a function of horizontal distance, where the dog 17 crosses, while the steel wire 21 is operated upon the thread 8. Therefore, increased relaxing is realized as a function of length of the selected stitch.

IPC: H01B5/14
Filed: 1986-12-19
Abstract: PURPOSE:To suppress cracks at an electrode part and to make it possible to suppress the increase in weight of the electrode part to a large extent, by constituting an electrode layer with an LB film, which consists of a charge-transfer complex, which is the combination of a charge donor and a charge acceptor. CONSTITUTION:When a molecule which has a hydrophobic group with appropriate strength at one end of a large hydrophobic group such as a long hydrocarbon chain is placed at the surface of water, the molecule takes an orientation so that the hydrophilic group is contacted with the water and the hydrophobic group is projected into the air. When the adhesion of this material to the water is stronger than the cohesion force between the molecules of the material and the area of the water surface is sufficiently wide, all the molecules are attached to the water surface and a single-molecule film is formed. Therefore, when the hydrophobic substrate (piezoelectric film) is vertically immersed in the water, on the surface of which the single-molecule film is formed, the hydrophobic group of the single-molecule film is attached to the surface of the substrate to form the first layer. When the substrate is lifted, the hydrophilic group of the single-molecule film is bonded to the hydrophilic group of the first layer to form the second layer.
