Inventor: SAKATA HIROMI
IPC: E04C2/40
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To prevent a warf or a deformation even when this composite board is used for a wall face and make a large-sized artificial marble board usable by forming a recessed part and a projecting part in a plate respectively in mutually opposite sides of a marble thin plate when the plate is stuck to the rear face of the artificial marble thin plate with an adhesive. SOLUTION: This composite board 1 is constituted of an artificial marble thin plate 2, a plate 3 made of a woody plate such as a particle board or the like, and an adhesive 4 such as a solvent type acrylic adhesive, an emulsion type acrylic adhesive, etc., combining these plates. When the plate 3 is stuck to the rear face of the artificial marble thin plate 2, the plate 3 and the marble thin plate 2 are mutually stuck together so as to shift each other to form a projecting part 31 and a recessed part 32. In this case, when the width of the projecting part 31 is α, and the width of the recessed part 32 is β, these are formed as α>β, and the front end of the projecting part 31 is butted against the front end of the recessed part 31 to fix the composite boards 1 one after another.  In this way, a gap having a width of α-β is formed between adjacent artificial marble thin plates 2, and the gaps are used as joints.

Title: Method and device for image processing
Inventor: TATSUMI SETSUJI
IPC: H04N9/79
Filed: 1986-09-02
Abstract: PURPOSE:To suitably execute gradation correction by using an input video signal whose variation in level is made small by means of input signal level variation buffering processing, and setting a highlight point and a shadow point. CONSTITUTION:In case the video signals inputted to sharpness circuits 12R, 12G, and 12B from A/D conversion circuits 10R, 10G and 10B are emphasized in contour, the contour emphasis of these video signals is eliminated in the sharpness circuits 12R, 12G and 12B. Also, since the drastic variation in level of a part of an input video signal is converted to a mild variation, noise included in input video signals 56R, 56G and 56B is eliminated. Therefore, a highlight point and a shadow point obtained from a cumulative histogram can be accurate ones of the input video signals. In such a way, a suitable gradation correction can be executed.

Title: Minimum light receiving level stabilizing method for light receiving circuit
Inventor: FUKUGAHARA TSUTOMU
IPC: H04B10/572
Filed: 1989-08-09
Abstract: PURPOSE:To make the required gain constant in an electric circuit by superimposing noise of variable quantity on an electric signal, and adjusting the noise level so as to deteriorate a light reception level versus error rate characteristic of a light receiving circuit within the permissible range. CONSTITUTION:When a dark current of a photoelectric element 1 is smaller than a required value, the noise with relevant quantity is inputted so as to be superimposed onto an electric signal. Thus, when the dark current of the photoelectric element 1 is smaller than the design value and minimum light reception level is lower than the design value, the noise generated in a noise generating circuit 4 is increased to deteriorate the light reception level versus error rate characteristic of a light receiving circuit within the permissible range. Thus, the minimum photodetection level is increased up to the design value. Thus, the minimum light reception level is always increased up to the permissible maximum level. Thus, the gain required for the electric circuit always can do with minimum.

Title: Resin mold type power electronic device
Inventor: YOSHIMURA MASAYOSHI
IPC: H01L23/28
Filed: 1985-09-20
Abstract: PURPOSE:To prevent the lowering of damp-proofing due to a mounting to a substrate by forming the shape of a molding section to a chevron on viewing from a plane and obviating an extension to the upper section of a line tying the center line of a pair of fitting holes shaped to a header of the upper edge of a central section. CONSTITUTION:A molding section 19 has predetermined thickness, and covers a semiconductor element 13, wires 16 and the inner end sections of leads 17. The plane of the molding section 19 takes a Conidae-shaped chevron, a top section thereof extends between a pair of fitting holes 12, and skirt sections thereof stretch along sections in the vicinity of the fitting holes 12. Since the deformation of a header section is reduced with a separation from the fitting holes 12 even when a mounting substrate, etc. are warped when a power semiconductor device is clamped and fixed to the mounting substrate, etc. by utilizing the fitting holes 12, the positions of corner edges are separated from the fitting holes 12, thus hardly deforming the header section in the lower sections of the corner edges. Accordingly, a joining section on a boundary between the header section and the molding section 19 is not peeled, thus preventing the lowering of damp-proofing and reliability.

Filed: 1985-09-20
Abstract: PURPOSE:To enable the floating quantity of the package substrate to arbitrarily modify according to the thickness of the mounting substrate by just exchanging the spacers for spacers different in the size of their protruded parts by a method wherein the spacers provided with the protruded parts on their peripheries are fitted between the lead pins. CONSTITUTION:Spacers 10 are fitted between lead pins 4, yet the spacers 10 each have spherical protruded parts 10a at the prescribed intervals on the bar- shaped member with a diameter of 1mm or thereabouts. When the spherical protruded arts 10a are abutted on the surface of a mounting substrate 11, the insertion of each lead pin 4 is stopped and a package substrate 3 is turned into a state of flotation over the mounting substrate 11 as much as the width length of the spherical protruded parts 10a of the spacers 10. In case the floating quantity of the package substrate 3 is wanted to modify, the desired floating quantity can be obtained by fitting spacers having the spherical protruded parts 10a made their width thicknesses differ mutually between the lead pins 4. By this way, the floating quantity of the package substrate 3 can be easily changed by just exchanging for spacers different in the width thickness of the spherical protruded parts 10a.

Title: Feedback type evaporator
Inventor: FUKUSHIMA SACHIO
IPC: F02M3/12
Filed: 1989-08-11
Abstract: PURPOSE:To prevent the occurrence of back bleed and prevent the interruption of a slow mixed air correcting air in normal engine operating state other than back bleed generating area by interrupting the slow mixed air correcting air in the back bleed generating area during the engine operating state. CONSTITUTION:When engine intake negative pressure and engine rotating speed of a specified area are detected during engine operation, an interruption signal is generated, and on the basis of this signal, an interruption control valve mechanism 22 forcedly interrupts a slow mixed air correcting passage 19. Hence, the transmission of the pressure fluctuation caused by the change of air bleed opening area into a slow fuel system passage 14 is prevented by the drive of a mixing ratio correction control valve 5. Thus, the negative pressure P2 in the slow fuel system passage 14 is regularly made larger than the negative pressure degree of the negative pressure P1 in a main fuel system passage 2, and the difference between the both is increased, whereby the negative pressure P1 is prevented from being larger than the negative pressure P2.
