Abstract:
An arrangement and structure for an oil pan system to permit mounting a vertical in-line engine in a vehicle in a horizontal or nearly horizontal attitude includes a cylinder block of the engine having an opening on the side wall thereof, a cover attached to the cylinder block where an ordinary oil pan is usually mounted, an adapter plate fastened to the lower side wall of the cylinder block and bottom of the cover, and an oil pan attached to the lower surface of the adapter plate. The adapter plate allows the oil pan to extend and always remain below the cylinder block, so that the return paths from the lubricated portions of the engine to the oil pan are shortened.
Abstract:
A lead-containing copper-based alloy is immersed into a weak acidic or neutral etching solution having a buffer effect which is formed by adding an organic acid into a complexing agent having a high ability to form a complexing ion with lead, and lead particles present on the surface of the lead-containing copper-based alloy are then removed. The complexing agent is one of an organic ammonium salt such as ammonium acetate, or ammonium citrate, or may be an organic sodium salt such as sodium acetate, sodium tartrate, and sodium citrate. Preferably, an immersion temperature of the alloy to the etching solution falls within a range of from 10 to 50° C. The etching solution is agitated with oxygen or a gas containing oxygen blown thereinto during the immersion of the alloy into the etching solution. An extremely low voltage of −0.3 to +0.2 V vs. NHE is applied from outside to the lead-containing copper-based alloy as an anode.
Abstract:
In a quick connector for piping 10 for detachably connecting a male member 12 to a female member 11, an O-ring 15 is interposed between the female member 11 and the male member 12 so as to form a seal therebetween, and the O-ring 15 is subjected to a low-friction treatment so that the O-ring can be moved in a direction of an axis of the quick connector 10 by a pressure of an employed fluid.
Abstract:
Disclosed is a method for the automatic, nondestructive, measurement of the eccentricity of a core wire in a coating composition coated upon an electrode, the measurement being formed by at least two sets of optical means, each including a light source and a line sensor. One of the optical sensors is positioned to measure the diameter of a coated portion of the core wire while at least one of the remaining sensors is positioned to measure the diameter of an uncoated portion. The positions and diameters of both portions are compared to find the eccentricity of the core wire. Where three sensors are used to measure the position and thickness of the exposed wire portion, the eccentricity of a misaligned or bent rod can be determined.
Abstract:
A surface flaw detector includes a light source capable of generating a laser beam, a material conveyance means provided for conveying a material to be examined in the direction transverse to the axis of the material and designed to let the material rotate on its axis at a fixed position or along the direction of conveyance, means for scanning the laser beam on the surface and in the axial direction of the material which is rotating on its own axis, optical means adapted to transmit the light reflected from the surface of the material to form a stationary optic image of the scanning means, light receiving means provided at the image forming position, and processing means adapted to discriminate the flaw signal upon receiving the output from the light receiving means.
Abstract:
An instrument panel comprises an elongated sheet member formed through the longitudinal length thereof with a plurality of depressions. The depressions provide for a weakening of resistance to deformation of the sheet member so that if the sheet member is struck by the passenger's head in a collision, it is permanently and plastically deformed and thus saves the passenger from injury.
Abstract:
Ferroelectric metal oxide crystalline particles are produced by first producing nanoparticles of a ferroelectric metal oxide and dispersing the nanoparticles in a gas phase. Then, the nanoparticles are processed by heat treatment with the nanoparticles being maintained in the gas phase in a dispersed state. The nanoparticles may be produced by using a laser ablation method. The ferroelectric metal oxide may have a perovskite crystal structure.
Abstract:
A fuel supply system for an internal combustion engine including a fuel tank having a resin liner. The fuel tank is constructed so as to withstand refueling of compressed gaseous fuel. Fuel filled in the fuel tank is supplied to the engine through a fuel supply passage. When the pressure within the fuel tank drops below a predetermined value, the supply of fuel to the engine is inhibited.
Abstract:
A sheet feeding apparatus with a sheet containing tray adapted to support a plurality of sheets and being shiftable between a sheet supplying position and a waiting position, a sheet supply roller for feeding out the sheet supported by the sheet containing tray at the sheet supplying position, a driving force transmitting device connected to the sheet supply roller and adapted to transmit a driving force from a drive source, and a holding device connected to the driving force transmitting device so that the sheet containing tray is shifted to the sheet supplying position by the driving force transmitted to the sheet supply roller and capable of holding the sheet containing tray at the sheet supplying position while the plurality of sheets are being supplied by the sheet supply roller.
