CONSTITUTION:A front cover 1 of an engine has a front wall part 11 and a peripheral wall part 12, and a power transmitting mechanism ...

PURPOSE:To provide the welding method for skin materials in which molten resin is not leaked out onto the surface sides of skins at the time of welding and flashes are not formed thereon. CONSTITUTION:The ends of two resin skin materials 12 and 14 are overlapped with the surface sides of respective skin materials being brought into contact with, and said overlapped section is clamped by high frequ...

PURPOSE:To prevent generation of noise and invasion of rainy water, to reduce the number of components and to decrease the number of operating steps. CONSTITUTION:A U-shaped cutout 6 opened above a valve mounting plate 2 is formed. After a valve 3 is mounted, a gap above the valve 3 is closed by a shielding plate 7 having a circular-arc-shaped lower edge 7b coincident with an upper part of the val...

PURPOSE:To reduce a noise level of an entire outdoor unit by suppressing interference sound and peeling sound generated at a grill as much as possible. CONSTITUTION:A sectional shape of a wing 3 held by a support rail 2 in an axial direction of an impeller is formed in a wing shape to have a pitch-chord ratio of 0.9-4 (0.1<=T/L<=4), 30-70% of position C/L of a maximum camber from a front edge (0.3...

PURPOSE:To count and control the number of dispersions with high precision with regard to a method for counting a dispersion object wherein microdispersion objects are counted when dispersed. CONSTITUTION:A plurality of microparticles 21 are charged each with a predetermined polarity and sprayed from the spray opening 22a of a nozzle 22. Then, a current value developed by spray of charged micropar...

In the production of foamed plastic articles using a screw extruder, it is known to introduce a gaseous foaming agent into the plastic while the latter is passing through the extruder. It has been found that a foamed thermoplastic with pores or cells of uniform size and distribution can be produced by passing a gaseous foaming agent, e.g. nitrogen gas through a central passage (8) extending substa...

A plurality of voltage converting stages are composed in parallel to be divided when operating so that the unnecesary consumption o...

Neurological testing apparatus by which the sense receptor's of a person can be tested. The apparatus is of a configuration to be held in the hand and includes a body having a front surface opposed to a rear surface to provide ample space for supporting a plurality of spaced apart covered substances thereon. The substances are each different from the other and each substance test one of a person's...

The invention relates to lids of easy-opening cans for perishable foodstuffs, and a method of obtaining them. These lids are composed of a metal foil and a plastics film, the metal foil having a mechanical non-traversing pre-incision corresponding to a tearing line and the thermo-shrinkable plastics film having a continuous depression situated opposite the mechanical pre-incision. The pre-incision...

A process for the selective surface dealumination of organic-containing zeolites by contacting the zeolite with dicarboxylic acid, such as oxalic acid. The treatment results in a reduction in surface acidity without a significant reduction in overall activity. The organic may be a directing agent used in the zeolite synthesis or introduced into the pores of the zeolite after thermal treatment.

Thickening systems for water-based building material mixes, composed of 0.01 to 2% by weight of a water-soluble cellulose ether, 0.01 to 2% by weight of polyvinyl alcohol and 0.005 to 1% by weight of boric acid or salts thereof, the respective percentages being based on the dry substance content of the building material mix.
