A heat-resistant hose for transport of high temperature fluid, wherein the inner surface of the hose in contact with said fluid comprises a material containing blended rubber of fluorinated rubber (FKM) and acrylic rubber (ACM). In particular, a heat-resistant hose for transport of fluid containing high temperature oil which comprises an inner tubular body composed of one or more layers at least the most inner layer of which consists of blended rubber of FKM and ACM, fiber reinforcements wound around the outer surface of said inner tubular body the thread extracting force of which the fiber reinforcements is not less than 1N/mm, and an outer tubular body composed of one or more layers bonded on the surface of said fiber reinforcements, said most inner layer preferably containing carbon black having the value (A.times.B) of not more than 3500 obtained by multiplying the value A of nitrogen adsorption specific surface area (m.sup.2 /g) by the value B (PHR) of part by weight of amounts of carbon black used is added to the blended rubber.

An air flow rate measuring apparatus includes a casing having opposite open ends, a flow rectifier mounted within the casing at an upstream-side portion thereof with respect to a direction of flow of fluid to be measured, and at least one fluid pressure detector which is mounted within the casing, and is disposed downstream of the flow rectifier, the fluid pressure detector including at least one differential pressure detector member. The differential pressure detector member includes a pair of tubular members of an identical configuration, and each of the tubular members has a flattened shape having opposed narrow side walls and opposed wide side walls, and at least one pressure-measuring port is formed through one of the opposed narrow side walls. The differential pressure detector member further includes a pair of plug members mounted on and closing opposite open ends of each of the tubular members, respectively, one of the pair of plug members having a pressure outlet port. The at least one pressure-measuring port in one of the pair of tubular members is directed toward an upstream side with respect to a direction of flow of fluid to be measured, thereby forming a total pressure-measuring port, while the at least one pressure-measuring port in the other tubular member is directed toward a downstream side, thereby forming a static pressure-measuring port.

An electrophotographic toner composition comprising (A) toner particles with an average particle diameter of 9 .mu.m or less comprising at least a binder resin and a colorant, and (B) an additive, wherein the additive is a fine metal oxide powder surface coated with at least one agent for imparting hydrophobic property selected from the group consisting of the following formulae (1), (2) and (3):R.sub.1 Si(X).sub.3R.sub.1 R.sub.2 Si(X).sub.2R.sub.1 R.sub.2 R.sub.3 Si(X).sub.1wherein R.sub.1 represents a substituted or unsubstituted alkyl group having a molecular weight of 113 or more, R.sub.2 and R.sub.3 each represents hydrogen, an alkyl group or an allyl group, and X represents chlorine, an alkoxy group or an acetoxy group. The toner composition causes no impaction to a carrier and no adhesion of the toner particles to a photoreceptor, and can form stable, sufficient images for a long time.

Several embodiments of remote control operators for adjusting the trim of a pair of marine propulsion devices. Each control system is designed so as to permit selective trim adjustment of either of the propulsion devices independently of the other and regardless of its trim adjusted position or for permitting simultaneous adjustment of both of said propulsion devices. A number of different types of circuits are illustrated for accomplishing this result and the adjusted propulsion devices may comprise either an outboard motor, the outboard drive of an inboard/outboard drive or the screws of a twin screw inboard drive.

A transformer with a toroidal magnetic core. The toroidal magnetic core is housed in an insulating case. The insulating case has a top and bottom annular winding frames. These frames provide radial winding conductor grooves. The top annular winding frame provides a plurality of grooves for guiding an inter-connecting conductor therein each of which is formed between two adjacent winding conductor grooves. The inter-connecting conductor is guided through said guiding groove to connect between the adjacent two unit coils.

A fluid pressure sensor apparatus includes one or a plurality of fluid pressure sensor elements. Each fluid pressure sensor element comprises a flat hollow structure which extends transverse to the direction of flow of a fluid. An upstream chamber is open through dynamic pressure measuring holes which extend in the direction of the flow, and a downstream chamber is open through static pressure measuring holes which extend transverse to the flow direction. The upstream chamber acts to average the dynamic pressure and the downstream chamber measures static pressure. An auxiliary ridge-like member is located downstream of the static pressure measuring holes.

A fuel scavenger for a two-cylinder, two-cycle horizontal upper and under type internal combustion engine. The engine has a crankcase with a revolving crankshaft which is turned by the reciprocating movement of a piston in each of the cylinders. A carburetor supplies air/fuel mixture to the crankcase via respective intake passages and reed valves. A fuel catcher is located in each crankcase, substantially shielded from the scouring action of air/fuel mixture impelled by the crankshaft, and the fuel catcher of each cylinder is connected to the intake passage of the other cylinder via a respective check valve.
