摘要:
A portable power working machine has an L-shaped top handle having a top grip portion that is attached to the front portion of the top of a main housing and extends longitudinally above and parallel to the top of the main housing and a rear coupling portion that is attached to the rear portion of the main housing. A side handle has a front grip portion that is connected directly to the front end of the top grip portion of the top handle and a diagonal grip portion that extends diagonally straight as viewed in side elevation from the front grip portion toward the lower end of the rear coupling portion of the top handle. The lower end of the diagonal grip portion of the side handle is connected directly to the rear coupling portion of the top handle.

A power transmission device is disclosed which is capable of easily, swiftly and appropriately altering the distance between the axes of a pair of transmission wheels such as pulleys, enabling an endless belt to be kept under constant and appropriate tension without necessitating a tension roller. This power transmission device comprises an endless belt wound around a pair of transmission wheels; and a cam-type adjusting mechanism which is interposed between a driving side supporting member and a driven side supporting member and configured to adjust a distance between the axes of the wheels. This cam-type adjusting mechanism comprises a supporting shaft secured to either the driving side supporting member or the driven side supporting member and disposed parallel to the rotational axes of the wheels; and a cam rotatably secured via a manipulating boss member to the supporting shaft.

A portable power working machine has an L-shaped top handle having a top grip portion that extends longitudinally above and parallel to the top of a main housing and a rear coupling portion that extends along the rear portion of the main housing. A side handle has a front grip portion that is joined to and extends horizontally and laterally from the front end of the top grip portion of the top handle and a diagonal grip portion which curves out and down from the front grip portion and extends diagonally straight as viewed in side elevation from the front grip portion toward the lower end of the rear coupling portion of the top handle. A starting footstool contiguous to a lower end of the diagonal grip portion extends horizontally to the vicinity of and is joined to the lower end portion of the rear coupling portion of the top handle.

An air cleaner provided with a bellows-like air cleaning filter includes an air permeable and pliable strip-like mesh element (3), a plurality of rectangular plastic frames (4) arrayed side by side with a predetermined pitch on one or both surfaces and along the full length of the mesh element (3), the plastic frames (4) being injection-molded and provided at both end portions in the width-wise direction with angled protrusions (5) having an approximately triangular cross-section and hinge portions (7) formed by thinning or linearly grooving a joint portion of the frames (4) between neighboring plastic frames (4). The bellows-like air cleaning filter is employed by transforming it into a cylindrical shape and fitting end caps (9) thereto.

摘要:
The present invention relates to a process for producing compost, characterized in that when the compost is produced by inoculating aerobic composting seed bacteria to an organic waste material, the process comprises: supplying oxygen while the waste material is stirred, and supplying water so that the water content of the waste material is 60±5%, and to a process for producing compost, characterized in that when the compost is produced by inoculating aerobic composting seed bacteria to an organic waste material, the process comprises, after begining of the fermentation, adding sugars to the waste material in a divisional manner before a main fermentation is transferred to the amine/ammonium metabolic system. Further, according to the present invention, an apparatus for producing compost is provided. The apparatus comprises: a fermentation vessel having an oxygen supplying means, a water distributing means, and a stirring means; and a control means for detecting or determining the moisture content of an organic waste material contained in the fermentation vessel to control, on the basis of the detected or determined result, the amount of water to be distributed by the water distributing means. According to the present invention, when organic waste materials disposed from food processing factories and the like is processed to produce compost of high quality, formation of ammonium and amines mainly causing unpleasant odors or generation of lower fatty acid which is a factor for a growth inhibition of plants can be suppressed, and the compost can be produced in stable, and within a short period of time.
摘要:
A two-stroke internal combustion engine having a crankcase provided with a crank chamber, a suction port which opens to the crank chamber, a scavenging passage opening into the crank chamber, and a crankshaft is provided with a flow control surface formed on an inner peripheral wall portion of the crank chamber which is capable of retarding the flow rate of unatomized raw fuel and which extends from the vicinity of the suction port to the vicinity of the scavenging passage. The flow control surface is comprised of a large number of intersecting unit ribs.

An internal combustion engine which comprises an engine body, and an air-intake side protective cover disposed at an air-intake side of the engine body, wherein the air-intake side protective cover is provided on the outer surface thereof with recessed grooves. The internal combustion engine may further comprise an exhaust side protective cover which is disposed in opposite to the air-intake side protective cover with the engine body being interposed therebetween and the recessed grooves are made to have substantially the same width and interval as those of a suitable number of heat radiating slit-like through-holes formed parallel with each other in the exhaust side protective cover.

A centrifugal clutch has a clutch boss including a hub fixed to a drive shaft, several guides that extend radially from the hub, and clutch shoe retaining flanges that extend radially outward from each of the guides. The centrifugal clutch also has a clutch drum disposed coaxially with the clutch boss and is rotatable about the driving shaft independently from the clutch boss. Clutch shoes are slidably fitted to the guides in a radial direction of the clutch boss, and a spring biases each clutch shoe radially inward. Resilient snaps hold each of the clutch shoes with respect to the clutch boss so that each of the clutch shoes is biased toward each of the flanges in an axial direction of the drive shaft.

Disclosed is a two-cycle internal combustion engine including a protruding edge portion formed in a section of a lower side surface of an intake port which is adjacent to a pre-compression chamber of a cylinder. This protruding edge portion serves to deflect air-fuel mixture introduced into the pre-compression chamber through the intake port so as to direct it to a bearing portion provided between a piston and a connecting rod. Further, a cut-in groove is formed in the protruding edge section and is adapted to allow any liquid remaining in the intake port to flow into the pre-comparison chamber.
