Large vibrations can be prevented from being generated during engine rotation. A control apparatus for driving a vehicle has an engine stop permission output control processing module which: reads engine rotational speed; determines whether the engine rotational speed takes a value within a predetermined stop disable range; does not output an engine stop permission when the engine rotational speed takes a value within the stop disable range; and outputs an engine stop permission when the engine rotational speed takes a value except the value within the stop disable range, and an engine stop control processing module which stops an engine when the engine stop permission is outputted. In this case, when the engine rotational speed takes the value except the value within the stop disable range, the engine stop permission is outputted to stop the engine.

In a work vehicle, an engine compartment is disposed forwards of a cab. An exhaust gas treatment device is disposed over an engine in the engine compartment. A radiator is disposed forwards of the exhaust gas treatment device (33) in the engine compartment. A blower is configured to generate an airflow passing through the radiator from back to front of the radiator. The exhaust gas treatment device is slanted with respect to a vehicle width direction for increasing a distance between the exhaust gas treatment device and the radiator towards a first lateral face portion. Further, the first lateral face portion includes air inlets facing a space between the exhaust gas treatment device and the radiator.

A chinrest pad system designed to hold a standard chinrest used with a string instrument that minimizes dampening of vibration and prevents damage caused by the metal components touching the edges of the instrument. The system includes pads located under the support surface of the chinrest member and on top of the lower lip plate used on the lower clamping member. The pads are specifically designed to partially engage the instrument's upper and lower edges and match the curvature of instrument surface immediately adjacent to the edge. Each pad also includes a rear extending lip that bends slightly around the upper or lower edge and extends rearward to prevent the metal rods used with the turnbuckles from contacting the rear surface. During assembly, the pads are positioned over the upper and lower edges so that the compression forces exerted by the support surface and the lower lip plate are centrally located over the sidewall transverse axis, thereby minimizing dampening of vibration.

A half thrust bearing having a semicircular ring shape for receiving an axial force of a crankshaft of an internal combustion engine is provided. The half thrust bearing includes thrust reliefs formed adjacently to end surfaces on both sides in a circumferential direction on a slide surface side which receives the axial force so that wall thicknesses become thinner toward the end surfaces. The thrust relief on a rear side in a rotational direction of the crankshaft or both thrust reliefs are formed so that a length of the thrust relief in an inner end portion in a radial direction of the half thrust bearing is longer than a length of the thrust relief in an outer end portion in the radial direction of the half thrust bearing.

The invention relates to the technical field of forklift batteries, and discloses an anti-shock and anti-falling forklift battery. The forklift battery comprises a protective box, wherein the bottom wall of an inner cavity of the protective box is fixedly equipped with two supporting legs. The anti-shock and anti-falling forklift battery is provided with pulling springs and sliding blocks, the battery will press a second U-shaped block and limit blocks when there is a shock so as to enable the second U-shaped block to drive supporting rods to press the sliding blocks downward, and then the sliding blocks move towards the left and right, so that the pulling springs are driven to stretch, the pulling springs can play a role of shock absorption, the battery is prevented from being contacted with the bottom wall of the inner cavity of the protective box to result in great shock and collision. The downward movement of the limit blocks will press fixing blocks to move downward, and the pulling springs will also be pressed to move downward, thereby being capable of playing a good anti-collision and shock absorption effect on the battery, preventing the bottom of the battery from resultingin collision and shock with the bottom wall of the protective box, playing a good role of shock absorption and shock resistance, and enabling the service life of the battery to be longer.

The invention provides a vibration generating device of which the entire configuration may have a small size in a thickness direction, which can obtain a large vibration, and which can give vibrations with a plurality of large frequencies. The vibration generating device includes a coil (5) wound around an outer peripheral surface of a core (4), a vibrator (3) vibrating due to a magnetic field generated by the coil (5), a magnetic field forming unit having a pair of magnets (7) oppositely disposed at both surfaces of the vibrator (3) so that the same polarities face each other or one magnet (7) disposed at one side surface of the vibrator (3), and an elastic support member (8) for supporting the vibrator (3) so that the vibrator (3) is capable of freely vibrating, wherein a vibrating direction of the vibrator (3) is set to be parallel to a fixed surface of the device, by means of a magnetic flux generated by the magnetic field forming unit (6).

In an electronic apparatus having a touch panel, four fixing cushions are fixed at four corners of a rear surface of the touch panel. The fixing cushions are further fixed to a fixing frame to support the touch panel against to the fixing frame. Pair of vibrating elements are fixed to the rear surface of the touch panel along edges, which are parallel to each other, of the touch panel. The vibrating elements elastically bend the touch panel to cause flexural vibration to the touch panel. The fixing cushions have softness to allow the touch panel to vibrate and hardness to serve as fulcrums of the flexural vibration of the touch panel.

A clearance which is not filled with a vibration-proof member is provided between an inner cylinder and an outer cylinder. A stopper member which is made of an elastic member is disposed in this clearance. When the amount of relative displacement, in the diametrical direction, of the inner and outer cylinders has exceeded a predetermined value, the stopper member is elastically deformed. A clearance in the axial direction is secured between the stopper member and that portion of the vibration-proof member which connects the inner cylinder and the outer cylinder. In this manner, a function of switching the spring constant can also be obtained in a solid type of mount without a perforation in the vibration-proof member which is made of an elastic member to connect the inner cylinder and the outer cylinder.
