摘要:
In a lever type hoist an operation handle (18) is provided between a stopper (17) provided at the axial end portion of a driving shaft (5) and a driving member (8) screwed on the driving shaft (5) so as to be movable in the axial direction but non-rotatable relatively to the driving shaft (5). A spring (19) for energizing the operation handle (18) toward the driving member (8) is provided to bring inclined surface (31a) of the engaging projection (31) provided on the operation handle (18) into elastic contact with an engaging stepped portion (37) of the driving member (8) during the time when the mechanical brake (13) is being operated, whereby the driving member (8) can be prevented from being reversely rotated while being accompanied by a returning operation of the operation lever (16) by the engaging resistance of a feed click (14) during the time when a hoist and traction operation is being conducted under the no-load condition.

In a hoist and traction machine including a free rotation control apparatus, a free-rotation spring 19, for urging an operating handle 18 toward a driving member 8 and also urging the driving member 8 in the brake releasing direction, is interposed between the driving member 8 and a stopper 17 provided on a driving shaft 5. When the operating handle 18 is pulled out, the driving member 8 is rotated to move away from a driven member 7 by a torsional urging force of the spring 19 and thereby a braking ratchet wheel 11 and braking plates 9, 10 is released. Engagement lugs 31 are then brought into resilient contact with free rotation surfaces 35 via an axial urging force of the spring 19 to maintain controlled free-rotation.

A camera module includes a lens held in a cylindrical holder and an image sensor disposed at a predetermined distance from the lens. The image sensor is disposed on a substrate. The holder integrally has a protrusion that protrudes toward the image sensor and an outer peripheral portion provided outside the protrusion, the lower end of the outer peripheral portion being lower than the lower end of the protrusion. The lower end surface of the protrusion is fixed to the upper surface of the image sensor with an adhesive, and the lower end surface of the outer peripheral portion is fixed to the upper surface of the substrate with an adhesive.

Disclosed is a fuel tank arrangement structure for a vehicle, which is designed to position a fuel tank 30 under a floor panel 4 forming a floor of a passenger compartment of the vehicle. In the fuel tank arrangement structure, at least a laterally inward portion of the floor panel 4 is formed as a convex floor portion 7 protruding upward from a general surface 8 of the floor panel 4, and at least a laterally inward portion of the fuel tank 30 is formed as a convex fuel-tank portion 30a protruding upward. The convex fuel-tank portion 30a is positioned within a space defined by the convex floor portion 7 while positioning the remaining portion of the fuel tank 30 at a height position lower than the general surface 8 of the floor panel 4, and a seat 9 (10) is positioned inside the passenger compartment and above the convex floor portion 7.

When a sending station intends to transmit data to a target station to which the sending station cannot establish a direct link, the sending station searches for a station, i.e., a relay station which can communicate with the target station by retrieving a communication possible/impossible node list.

A material to be treated containing solid particles in a liquid is stirred together with milling media, and irradiated with ultrasonic waves during stirring to finely mill the solid particles to nanometer size and disperse the solid particles in the liquid. The ultrasonic waves create cavitation in the liquid and upon decay of the cavitation, shock waves are produced that cause the solid particles to vigorously collide with one another and with the milling media and these collisions, together with the shearing forces created by collision of the milling media, can produce on a commercial scale nano particles having an average particle size of at most 100 nm.
摘要:
A mine detector is provided for detecting buried land mines safely and promptly. A sensor head (12) is connected to a detector body (1) through hinges (11-1 to 11-4) and arms (12-1 to 12-3). The sensor head (12) includes a transmitting and receiving means for emitting electromagnetic impulses to the ground within a range of detection of land mines. When the transmitting and receiving means receives electromagnetic waves reflected from a land mine, information on the three-dimensional structure of the land mine buried under the ground is generated on the basis of the time of arrival of the reflected wave, the level of the reflected wave and the x and y coordinates of the transmitting and receiving means, and the information is displayed on a display (1). The detector is also applicable to the inspection of steel rods and bars for concrete reinforcement.

A dispersing and grinding apparatus comprises a vessel having an inlet for receiving a material to be processed and an outlet for discharging the processed material. A rotor is rotatably disposed within the vessel and positioned relative to the inner wall of the vessel to define therebetween a narrow, annular flow path for the passage therethrough of a mixture of the material and a grinding medium. The rotor has a plurality of axially extending grooves on the periphery thereof for guiding the mixture in the circumferential direction as the rotor rotates. The rotor is separated into a plurality of processing zones in the axial direction thereof, and the grooves in each processing zone are phase shifted in the circumferential direction with respect to the grooves in adjacent processing zones. When the mixture transfers from one processing zone to an adjacent processing zone, the velocity difference of the mixture is adjusted so that the mixture advances, as a whole, at approximately equal velocity through the narrow, annular flow path whereby the material is uniformly ground and dispersed.

An image generation system that generates an image includes: a movement control section that moves a player's moving object in a virtual three-dimensional space based on input information; and an image generation section that generates an image of the virtual three-dimensional space viewed from a given viewpoint. The movement control section performs a follow-up control process that causes the player's moving object to follow a target moving object based on previous movement information about the target moving object.
