Abstract: In a process of casting a rocker arm as one piece from high chrome cast iron, a Ca-Si base addition agent is added to the molten metal in an amount of 0.3 to 0.6% by weight. The agent is effective as a globulizer to round high-hardness carbide precipitates directing toward the casting surface.

Also, a method for producing such antistatic polyester film is described.

Abstract: An audio apparatus incorporating a CD player or a cassette tape deck and a radio receiver as integral audio components, includes a photosensor; a means for detecting an operating state of each audio source; and a drive mode switching means for automatically changing the photosensor to a continuous active mode or to an intermittent active mode according to a detection output of the source detecting means. When the CD or cassette tape is inserted, the active source is automatically switched to the corresponding CD player or cassette tape deck. Further, the photosensor is placed in the continuous active mode to eliminate noise generation when a source other than the CD or cassette tape is in operation. It is switched to the intermittent active mode to reduce power consumption when none of the sources is in operation.

Abstract: The front structure comprises a cowl top panel located on the engine compartment side connected to a dash upper panel located on the vehicle cabin side to form a closed box in cross section. A portion of the vertical front wall of the cowl top panel is provided for installation of a motor unit of windshield wiper. This portion is located at a position which does not laterally overlap either vehicle strut housing. The horizontal base of the dash upper panel at the installation portion is at the lowest height of the cowl. A drain hole is provided near this lowest position.

Abstract: A high strength high chromium cast iron contains fine particle precipitated hard carbide. The precipitated hard carbide has an average particle size of 20 .mu.m or less and hardness of Hv 500 or more in martensite base matrix, and has area ratio in a range of 30% or more and 45% or less. The precipitated hard carbide has spheroidal ratio (surface area of sphere circumscribing the precipitated hard carbide versus actual surface area of precipitated hard carbide) of 40% or more.

Abstract: A polyester film having on at least one surface thereof a primer layer comprising a crosslinked product of a polyurethane having at least one functional group selected from a carboxyl group, a sulfo group, a hemisulfate group, and salts of these groups and a polyepoxy compound. The polyester film having a primer layer can be produced by coating an aqueous primer coating composition comprising a polyurethane having at least one of a carboxylic acid salt group, a sulfonic acid salt group and a hemisulfate salt group on at least one surface of a polyester film before its crystallization and orientation are completed, and thereafter completing the crystallization and orientation by subjecting the coated film to drying, stretching and heat-treatment, and is useful as a base film for magnetic recording media.

Abstract: A roll-over valve includes a valve body wherein a raised seat portion which a position sensitive ball rests on is disposed below an inlet opening via which fuel vapors enter into the valve body chamber. A ball follower has a top member disposed below the inlet opening and adapted to close the inlet upon being moved toward the inlet by the ball.

Abstract: An inside arrangement to be fixed to an interior bottom of a fuel tank for surrounding a fuel outlet comprises a main reservoir of metal and a complementary reservoir of synthetic resin. The main reservoir is shaped like a rectangular box to form a reservoir chamber therein, and formed with a mounting hole. The complementary reservoir has an antechamber formed therein, and a tubular portion projecting outwardly from one side wall and having stopper projections. The complementary reservoir is fixed to the main reservoir simply by inserting the tubular portion into the mounting hole of the main reservoir.

Abstract: Multi-layered hollow coil and apparatus and method of manufacturing thereof disclosed which includes a first regularly wound first portion of a coil due to a wire from a wire source by rotation of a coil metrix on a rotatable axle and subsequently spirally wound second portion due to a wire accumulated on a winding roller by reverse rotation of the coil matrix which is disposed between two flanges. In the first wound portion of multi-layers, layers in odd numbers are wound N times and other layers in even numbers are wound N-1 times, and the layers excepted a first layers are wound between crests of windings of the lower layer. The first wound portion is pressed between the flanges by a movable flange thereof and electrically melt.

Abstract: An in-tank fuel feed pump supporting device comprises a plurality of stays and a single pump vibration damping elastic member. Each stay is formed with an oblong elastic member holding recess and the damping elastic member is formed with a plurality of tabs or a flange so as to be fitted to the oblong holding recesses of the stay. The elastic member is so disposed between a fuel feed pump and the stays as to cover the fuel feed pump and be deformed substantially in only shear mode when the fuel pump vibrates in the axial direction thereof. Therefore, it is possible to effectively damp the fuel pump vibration energy, prevent fuel pump noise from being transmitted to the outside of the fuel tank and reduce the manufacturing cost, simultaneously.

Abstract: This invention provides an improvement of an apparatus and method of coiling an insulating electric wire in an insulating tube which is supported within a U shaped groove of a supporting frame provided on a stand. The wire is fed into the tube from a wire supporting roll by a wire lead mechanism having a driving friction roll and a vibratory friction roll controlled by a spring.

Abstract: An improved support comprising (A) a base plate and (B) an adhesive layer formed on the surface of the base plate is provided for making a printing plate from a liquid photosensitive resin. The improvement resides in the inclusion of a tertiary phosphite or tertiary phosphine in the adhesive layer. The improved adhesive layer acts to give reliefs of a good shoulder shape, and this action can be retained over long periods of time.In an alternative embodiment, an activating layer (C) containing a tertiary phosphite or tertiary phosphine is formed on the adhesive layer.

Abstract: A support convenient for preparing a printing plate in situ using a liquid photosensitive resin of an unsaturated polyurethane resin is disclosed. This support consists of a base plate and coated thereon a layer of a composition consisting of a mercapto-containing ester obtained by polycondensing a thiocarboxylic acid or thioalcohol with a polyglycol or polycarboxylic acid or an aromatic tertiary amine and a polymer binder. The support of this invention, which has a broadened base of a sectionally trapezoidal configuration, provides a relief image that is firmly adhered to the support.
