Abstract: An idling stop control system stops an idling of an engine so as to automatically stop the engine in the case where a predetermined condition on automatic stop of the engine is established and releases the automatic stop of the engine so as to restart the engine in the case where a predetermined condition on restart of the engine is established in accordance with a driving condition of the vehicle. The idling stop control system recognizes a type of an object in front of the vehicle and restarts the engine depending on the type of the object in front of the vehicle even if the engine is in the automatic stop and the restart condition of the engine is not established with respect to the driving condition.

Abstract: A continuously variable transmission having a primary pulley and a secondary pulley on which a belt wound on the primary pulley is fitted. The width of the groove on the primary pulley is adjusted by the oil pressure in the primary hydraulic chamber in the primary cylinder, the width of the groove on the secondary pulley is adjusted by the oil pressure in the secondary hydraulic chamber in the secondary cylinder. The switching operation between the speed change operation in a state in which the line pressure is supplied to the secondary hydraulic chamber and the primary pressure is supplied to the primary hydraulic chamber by the oil passage switching valve, and the speed change control in a state in which the line pressure is supplied to the primary hydraulic chamber and the primary pressure is supplied to the secondary hydraulic chamber can be performed.

Abstract: A low bulk density hollow fine powder of alkali metal compound can be produced from an aqueous solution of the compound by one step. The method for producing a low bulk density hollow fine powder of alkali metal compound according to the present invention comprises a step of contacting an aqueous solution of an alkali metal compound with a pulsating combustion gas.

Abstract: A valve timing controller for varying the rotating phase of a cam shaft which drives a valve of an internal combustion engine. A pulley is disposed on the circumference of the cam shaft at an end to be freely rotatable. In the pulley, a first hydraulic chamber and a second hydraulic chamber are made, and these hydraulic chambers are separated in the circumferential direction of the pulley by a vane located on the circumference of the cam shaft. By controlling the pressures in the first and second hydraulic chambers, the vane is set selectively in a middle position, a valve timing retardation position which is an opposite position with respect to a pulley rotating direction and a valve timing advance position which is a farther forward position with respect to the pulley rotating direction. The cam shaft rotates with the movement of the vane.

Abstract: A variable lift height valve driving device which drives a valve of an internal combustion engine, varying the lift height of the valve. An inner shaft is disposed in a hollow cam shaft to be capable of reciprocating along the axis. A primary cam which has a primary cam surface is fitted around the hollow cam shaft at a specified position, and a secondary cam which has a secondary cam surface is fitted to the primary cam. With movement of the inner shaft, the secondary cam moves such that the secondary cam surface is set in a position to be on a level with the primary cam surface or in a position to protrude outward from the primary cam surface.

Abstract: A heat recovery system is disclosed for a pulse combustion drying system in which the exhaust gas of combustion from a pulse combustor passes successively through a dryer, a product collector and a scrubber. The heat of the exhaust gas is recovered in the scrubber by spraying with water or other liquid and transferring by heat exchange the heat absorbed by the water to compressed air, and passing the heated compressed air successively through a membrane heat exchange tube on the wall of the product collector and a membrane heat exchange tube on the wall of the dryer. The air is discharged finally in an air-injection nozzle of the pulse combustor.

Abstract: A spoiler to be mounted on rear part of an automobile comprising a movable plate capable of freely opening and closing itself and which forms a part of an upper plate of a main body. A stop lamp is mounted on the movable plate. The movable plate and the stop lamp interlock a foot brake of the automobile so that the movable plate is opened and the stop lamp is lit when driver steps on the foot brake. The stop lamp comes out on the rear spoiler and emits a beam light rearward. When a driver releases the foot brake, the movable plate is closed and the stop lamp is put out.

Abstract: It is an object of the present invention to provide a pulse combustion method and a valveless pulse combustor in which the strong sound wave energy and the combustion gas generated by explosions in the combustion chamber are effectively used for drying of a substance with no waste of sound wave energy and heat of the combustion gas.A pulse combustion method according to the present invention is characterized by a step of pushing the sound wave energy and the combustion gas which flow toward the air intake back to the combustion chamber by jetting a compressed gas toward the air intake. By means of this step, the sound wave energy and the combustion gas which were generated at the time of explosion in the combustion chamber and flow toward the air intake are pushed back to the combustion chamber and further to the exhaust pipe by a stream of the compressed gas. This enables the sound wave energy and the combustion gas which have been conventionally wasted to be used for drying of a substance.

Abstract: A barking machine has a container for processing logs formed with openings each extended lengthwise of the container, a transfer guide plate disposed between the openings, multiple notches formed in the openings, lower and side cylindrical rotators each having protruding barking blades on its outer periphery which pass through the notches, and a supporting member for retaining the transfer guide plate. In such a construction, the rotors are partially inserted into the openings, respectively. The lower rotor rotates so that its barking blades move toward the side opening, and the side rotor rotates so that its blades move upwardly. With this arrangement, it is possible to prevent the logs from being blocked between the rotators or falling from therebetween, and to provide a strengthened transfer guide plate with no deformation, thereby enhancing the circulating of logs in the container and the barking operation.
