Abstract: A vehicular backing operation assist apparatus is coupled with a movement direction demand unit for demanding a forward or backward movement of the vehicle and a change detection unit for detecting a change of a state of the vehicle taking place in association with a start-up of the vehicle. A reverse departure, which is a backing operation for exiting a parking state, is determined to be performed if a transit period from when the change of the state is detected to when the backward movement is demanded, is within a predetermined period. A reverse parking, which is a backing operation for entering a parking state, is performed, if the transit period is greater than or equal to the predetermined period. An assist control unit then provides an assist item for a backing operation relative to either the reverse departure or the reverse parking, which is determined to be performed.

Abstract: A dry shaver has an elongated shaving head with a lengthwise axis. The shaving head carries semi-cylindrical first and second outer cutters disposed on its opposite width ends, and a semi-cylindrical finishing cutter and a slit cutter interposed between the first and second outer cutters. The finishing cutter has a finishing foil which is deeply curved than a foil of the first and second outer cutters into an arcuate contour having a width less than that of the first and second outer cutters. The finishing foil disposed behind the first outer cutter comes into contact with a user's skin to make closer shaving than the first and second cutters. A skin guard project between the first outer cutter and the finishing cutter to protect the skin from being pressed excessively to a side of the finishing foil when moving the shaving head across a user' skin with the first outer cutter leading in a moving direction, thereby reducing skin irritation.

Abstract: A shaving foil for a dry shaver has a plurality of perforation arranged in an array. The shaving foil is formed in its skin contact surface with a plurality of recesses which define a thin section of reduced thickness at the recesses, while leaving thick sections at the remainder of the foil. Each perforation is configured to have its circumference defined partly by the thin section and partly by the thick section. Both of the thin and thick sections can come into contact with a user's skin for smoothly guiding hairs into the perforations to make close shaving without irritating the skin, while the shaving foil is moved across the skin. Especially, the thin sections act to cut the hairs shorter than the thick section, as wall as to raise flattened hairs into the perforations for successfully cutting the flattened hairs.

Abstract: An axle driving apparatus in which a hydraulic pump and a hydraulic motor which constitute a hydrostatic transmission are disposed on a center section. In a horizontal portion of the center section are provided a pair of linear oil passages in parallel to each other. A pair of arcuate ports are provided on a pump mounting surface formed on the horizontal portion of the center section. The pair of arcuate ports are substantially perpendicular with respect to the direction in which the oil passages extend. The axis of slanting movement of a movable swash plate of the hydraulic pump extends laterally of the vehicle body on which the axle driving apparatus is provided. The rotating direction of an arm provided on a control shaft for slantingly operating the movable swash plate is coincident with the operating direction of a control rod connected with a speed changing member. Thus, the link mechanism for connecting the speed changing member and the control arm for the movable swash plate is simplified.

Abstract: A reciprocatory dry shaver has a shaving head carrying an outer cutter, and an inner cutter. An actuator is mounted in the shaving head for driving the inner cutter. The actuator includes an oscillator which carries a joint for driving connection to the inner cutter. Resilient coupling links are provided to support the oscillator to the shaving head in order to allow the oscillator to reciprocate relative to the shaving head. The resilient coupling link has its upper end coupled to the oscillator and has its lower end which is farther away from the inner cutter than the oscillator and is anchored to the shaving head. Thus, the oscillator is supported as being floated or lifted with respect to the shaving head, thereby being allowed to travel along a path which is somewhat arcuate in coincidence with the arc of the outer cutter.

Abstract: If the detected distance from a vehicle to a detected obstacle is equal to or greater than a preset distance, then a vehicle periphery monitoring system performs an image processing process on a captured image of the periphery of the vehicle to acquire the height of the vehicle. If the acquired height of the obstacle is less than a preset height, then the obstacle is displayed as a safe obstacle. If the acquired height of the obstacle is equal to or greater than the preset height, then the obstacle is displayed as a dangerous obstacle. The vehicle periphery monitoring system is able to indicate to the vehicle driver whether the detected obstacle is dangerous or safe. The vehicle periphery monitoring system is not required to perform the image processing process on the entire area of the captured image, and does not require a CPU having a high processing capability.
