Title: Outside air intake structure for vehicle
Inventor: SAITO MITSUHIRO
IPC: B62D25/10
Filed: 1989-02-20
Abstract: PURPOSE:To secure the rigidity of a body by connecting a front end opening of an air guide to a grille, and interpositioning an upper surface opening of the air guide between the grille and a bridge panel, and communicating the upper surface opening of the air guide with an air duct part of an engine hood through a guide seal. CONSTITUTION:A part of the outside air led from a grille 5S as a vehicle travels is directly taken into a front end opening 20a of an air guide 20. The outside air passing through the air guide 20 is led out from an upper surface opening 20b and is led to an air intake 32 of an air duct part 28 provided in an engine hood 21 through a guide seal 33, and passes therethrough, and is blown out from an air blow out port 34 toward an intercooler 4 through a blow out side guide seal 35. In this case, since the grille 5S and the air guide 20 are connected mutually and the guide seal 33 is interpositioned between the air guide 20 and the air duct part 28, the air leakage is eliminated to improve the suction efficiency, and opening a windguide port in the bridge panel 6 is not necessary.

Title: Bearing device
Inventor: KONNO DAISUKE
IPC: F16C17/04
Filed: 1992-01-30
Abstract: PURPOSE:To improve the rotational performance and reduce vibration by using gas as a thrust dynamic pressure bearing fluid, providing a void by a radial cylindrical part, a radial sleeve and a thrust plate, using a liquid as a radial dynamic pressure bearing fluid, and providing a small hole for a liquid reservoir in the radial cylindrical part. CONSTITUTION:A lubricating liquid is held between the inner peripheral surface of a radial sleeve 6 and the outer peripheral surface of a radial cylindrical part 4, and dynamic pressure is generated by gas between both end surfaces of the radial sleeve 6 and the opposite surfaces of a thrust plate 3 by the rotation of a hub 7, whereby the radial sleeve 6 is supported and rotated. The gap between the outer peripheral surface of the radial cylindrical part 4 and the inner peripheral surface of the radial sleeve 6 is very small, and a void 13 surrounded by the chamfering portion of the radial cylindrical part 4 and the radial sleeve 6 and the thrust plate 3, is large, so that a liquid is kept from entering the thrust gap. Even if the capacity is increased by the temperature rise of a liquid during rotation, a surplus liquid is absorbed by the small hole 8 of the radial cylindrical part 4. Thus, the radial bearing load capacity can be improved so as to enable stable rotation regardless of the attitude.

IPC: F28F19/06
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger made up of a resin tube which eliminate adverse effect on a liquid in a liquid storage tank, while being effective for dielectric breakdown with a simple manufacturing. SOLUTION: A conductive material layer 2 is formed being adhered onto an internal surface of a resin tube 1 to lower a resistance value of the resin tube 1, and an electric charge generated by friction is grounded outside by the conductive substance layer 2 so that the electric charge will not be retained exceeding a fixed value to prevent the formation of a pinhole as caused by a dielectric breakdown. Since the conductive substance layer 2 is formed on the internal surface of the resin tube 1, the conductive substance layer 2 is will not dissolved out into the liquid storage tank, thereby eliminating adverse effect on a liquid. Moreover, the conductive substance layer 2 is formed inside the resin tube 1 only by such a simple work as adhesion by spraying, coating or chemical plating, thereby simplifying the manufacturing while eliminating damage to the inside of the resin tube 1.

Title: Line driver
Inventor: MURAKAMI NORIO
IPC: H04B3/04
Filed: 1989-02-20
Abstract: PURPOSE:To obtain an inexpensive and miniaturized transmission part in pulse width modulation communication by using a line driver which inputs a mark and a space signal to a comparator and outputs a pulse having undershoot from an amplifier. CONSTITUTION:When a mark pulse is inputted, the pulse is inputted to the amplifier 1 and the comparator 2. The comparator 2 outputs a signal of H level by comparing the pulse with the ground level, and charges a capacitor C by operating switches SW1 and SW2. Next, when the space signal is inputted, the comparator 2 outputs the signal of L level, and discharges the capacitor C by switching the SWs 1 and 2. At this time, since the voltage of the capacitor C is inputted to the amplifier 1, the voltage at the inversion terminal of the amplifier 1 rises, and the pulse having the undershoot is outputted. The transmission part can be manufacted inexpensively and miniaturized by using such line driver in the amplification and attachment of undershoot of the pulse of the transmission part.

Title: Liquid fuel combustor
Inventor: IWASAKI NOBUHIRO
IPC: F23D11/10
Filed: 1980-03-31
Abstract: PURPOSE: To eliminate odor with a higher ignitability by heightening the concentration of a premixed gas with increase in the resistance of a blowing passage at the ignition.  
     CONSTITUTION: As soon as the preheating ends with a combustor 3 heated by a heater 3c, a blower 1 starts to work. At the same time, a solenoid 13 is energized to close a passage 11a with a valve sheet 12. In this case, the passage continues to be closed until the combustion becomes stable after the ignition and then is opened. At the ignition, the closure of the passage 11a reduces the amount of air raising the pressure in front of a partition 11, and an oil stabilizer forces out the more amount of the liquid fuel 5 to lower the rate μ of air surplus thereby improving the ignitability.

Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain a photographic base paper having bright and glossy golden printing on its back surface which is produced by ordinary gravure system by using ink obtained by including interference pigment and special water soluble binder in printing ink. SOLUTION: The effect of the interference pigment (bright golden pigment and bright metallic pigment) is based on the selective reflection of a light beam. Especially, the proper interference pigment is mica pigment (deformed mica particles) and the core part of mica particle having plate-like shape has one or more metallic oxide layers. This generates an interference effect in visible light. TiO2 and/or Fe2 O3 is especially desired in order to coat the mica particle. A desired coloring effect is attained according to the type and the thickness of coating material. The interference pigment is used by combining ordinary translucent chromatic pigment in the printing ink. The water soluble binder or water dispersion binder, for instance, polyvinyl alcohol or polyvinyl pyrrolidone is especially sutiable for the binder.
