In a duty control solenoid valve, there are provided a guide body for shutting off a fluid passage and in which a plunger is slidably guided, plural stages of flow control ports which are provided in the guide body and are opened or closed in response to the movement of the plunger, a plurality of return springs in response to the plural stages of flow control ports whereby the excitation energy of the electromagnetic coil can be switched to plural stages or the electromagnetic coils are selectable separately, thereby varying the opening areas of the plural stages of flow control ports.

Abstract: A vehicle speed determining device determines a running speed of a vehicle, on the basis of pulses received from a vehicle speed sensor. A first determination that the running speed of the vehicle has been zeroed is made, if a next pulse has not been received from the sensor, within a predetermined first length of time after the reception of a last pulse from the sensor. A second determination that a period of the next pulse to be received next is abnormally long is made, if said next pulse has not been received within a predetermined second length of time after the reception of the last pulse. If the second determination is made, the first determination is inhibited until the next pulse has been received.

Abstract: A shift control apparatus for an automatic transmission of a motor vehicle is disclosed. The shift control apparatus includes a shift control device for automatically shifting the transmission according to a predetermined shift control pattern, on the basis of a speed of the engine and a currently required output of the engine. When a vehicle driver operates to re-accelerate the vehicle after deceleration with the transmission shifted down to the low-speed gear position, the transmission is shifted up from the lower-speed gear position to the high-speed gear position having the smaller speed reduction ratio than the lower-speed gear position, if a predetermined period of time has not elapsed after the low-speed gear position is established.

Abstract: The present invention relates to a method for producing a tobacco raw material having at least a part of its surface coated with a silical gel, which comprises adding silica sol to the tobacco raw material and subjecting the silical gel to gelation.

Abstract: A musical information digital interface processing unit is interposed between a host processor, such as a personal computer, and an electronic musical instrument for interfacing the host processor and the electronic musical instrument by converting the data format of musical information. The musical information digital interface processing unit is composed of: an input device for receiving musical information and time information linked to the musical information from the host processor; a storage device for storing the musical information and the time information received through the first input device; a first output device for sequentially sending out the musical information at a timing determined on the basis of the time information to the musical instrument and a second output device for sending out in the first data format the musical information at the timing to the host processor.

Abstract: A differential motion limiting device, for a power transmission device for four wheel drive vehicle, to regulate differential motion of a center differential device includes a wet-type multi plate clutch and an hydraulic actuator. And a switching valve is attached to an oil passage to the hydraulic actuator. In normal running condition, a switching valve is in connecting condition, and a hydraulic pressure being varied by driving conditions is applied to a hydraulic actuator. Under this condition, the clutch is slippingly engaged by certain engaging force so that torque, per certain ratio, is transmitted to the front and the rear wheels. In high speed condition, such as the maximum speed state like an overdrive, or a vehicle speed more than 100 km/h, sensors detect such state, then the switching valve is switched, and the clutch is released. As a result, lubrication oil is flowed between friction plates and separators of the clutch to release heat therefrom.

Abstract: A power transmission device for four wheel drive vehicle includes a differential motion limiting device, for limiting differential motion of a center differential device, which is made up by a wet-type frictional clutch and a hydraulic actuator. Under running condition, the frictional clutch is engaged by certain engaging force, and considering frictional coefficient of roads, the clutch is engaged with some slips so that torque distribution to front and rear wheels becomes even (50:50), then torque is distributed from the center differential device to front and rear wheels. The line pressure is applied to the hydraulic actuator through a regulator valve. In normal running condition, the regulator valve reduces the line pressure pre certain ratio, the reduced pressure is applied to the hydraulic actuator. In the case the manual valve being shifted to R range or low speed position, the regulator valve is switched to apply the line pressure directly to the hydraulic actuator.

Abstract: The present invention is directed to a method of caustic alkali treatment, wherein the knitted work extended in the lengthwise direction and shrunken in the widthwise direction due to the scouring (or degumming) and the bleaching treatment is, after being returned to the condition of the length and the width before the scouring (or degumming) and bleaching treatment, able to be subjected to the caustic alkali treatment and the washing treatment as it is in such a natural state as when it is knitted by a knitting machine, whereby the knitted work is never short of width as is the case with the prior art method of treatment.

Abstract: A double-break puffer-type compressed-gas circuit-interrupter is provided having a common piston-and-cylinder arrangement for simultaneously forcing a blast of compressed gas through suitably-disposed jet apertures into a pair of serially-established arcs, the operating arrangement being such that there occurs simultaneous operation of the piston-and-cylinder arrangement, together with opening motion of the bridging cross-bar, electrically and mechanically interconnecting the two movable contacts.An ancillary feature of the invention involves the provision of suitable arc-horns, associated with each of the break structures, so that the inherent looping of the electrical circuit through the circuit-interrupter results in electromagnetic repulsion forces, to exert an outward electromagnetic force exerted upon each of the two serially-related arcs.
