A vehicle drive apparatus for supplying oil pressure to a hydraulic servo at restart of an engine. The vehicle drive apparatus includes an accumulator that accumulates the oil pressure, an electromagnetic switching valve that retains oil pressure of the accumulator when an oil pump is stopped, a switching valve control unit that controls opening and closing of the electromagnetic switching valve, and a restart determining unit that determines whether or not to restart the vehicle drive source from a stopped state. When it is determined by the restart determining unit to restart the vehicle drive source, the switching valve control unit is started so as to supply the oil pressure accumulated in the accumulator to the hydraulic servo. As a result, engine friction engagement elements are quickly engaged to enable starting of a vehicle.

A gas current toner classifier has a material feed nozzle, a Coanda block, a classifying wedge and a classifying wedge block having the classifying wedge. The Coanda block and the classifying wedge define a classification zone, and the classifying wedge block is set up in the manner that its location is changeable so that the form of the classification zone can be changed. A method of producing toner using said classifier is also described.
摘要:
An elastic wave is applied to an object under the ground, so that an elastic wave which varies in accordance with the material and shape of the object under the ground is detected and the detected elastic wave is collated with characteristic data such as elastic wave data, or the like, of various objects registered in advance to thereby identify/discriminate the object under the ground. A vibration generating probe and a vibration receiving probe, or, alternatively, a vibration generating and receiving probe is put into the ground so as to come in contact with an object under the ground. Then, the vibration generating probe or vibration generating and receiving probe is hammered to generate an elastic wave. At least one of one longitudinal wave and two transverse waves of the elastic wave which has propagated to the object under the ground is received by the vibration receiving probe or vibration generating and receiving probe. The vibrations of the elastic wave are converted into an electrical signal by a vibration sensor, and frequency response characteristic (and/or time-response characteristic) of the elastic wave is detected by a signal processing portion or by a signal processing portion and a data processing portion. The characteristic data is compared/collated with elastic wave data of various objects under the ground collected in advance, so that an unknown object under the ground is identified/discriminated.
摘要:
An image-forming apparatus which does not unfavorably influence its surrounding environment when in use and is excellent in durability of use and safety is provided. In the image-forming apparatus, a photosensitive layer is disposed on the outer surface of a closed-loop substrate drum, while a charge device, an exposure device, a developing device, a transfer device, a fixing device, and a cleaning device are provided around the substrate drum. The substrate drum is made of a light element. The charge device is constituted by a charging X-ray generation member, which is disposed within the substrate drum and emits an X-ray through the substrate drum and photosensitive layer so as to electrolytically dissociate the air on the surface of the photosensitive layer, and an electric-field application member which guides, by means of an electric field, a gaseous ion formed by this electrolytic dissociation to the surface of the photosensitive layer. The cleaning device is constituted by an erasure X-ray generation member which ionizes the air on the photosensitive layer, in which a coloring fine particle remains, upon irradiation of an X-ray emitted from within the substrate drum through the substrate drum and the photosensitive layer, while generating a carrier within the photosensitive layer.
