A vehicle speed responsive power steering apparatus enables a pressure which acts upon a power cylinder to be variably controlled in accordance with a vehicle speed or the like, thus allowing an assisting force to be controlled in a variable manner. A control valve CV selectively connects a pump P and a tank T to left and right chambers CL, CR of a power cylinder. The control valve comprises a first and a second fluid pressure bridge circuit 10, 20. The first fluid pressure bridge circuit includes a left and a right path 12, 13, in which a first and a second pair of variable throttles 1R, 1L and 2L, 2R are disposed which are opened or closed in response to a steering operation. The left and the right chamber of the cylinder are connected to the respective paths at the junctions between the variable throttles. A pair of paths 21, 22 branch from a supply path 11 extending from the pump, and a second fluid pressure bridge circuit is defined between the paths 21, 22, in parallel relationship with the first fluid pressure bridge circuit. The second fluid pressure bridge circuit includes variable throttles 3L, 3R, 4R, 4L which are opened and closed in response to a steering operation, and a vehicle speed responsive variable throttle valve 6 which is controlled to be opened or closed in accordance with a vehicle speed.

A power steering apparatus includes a main hydraulic path, a reactive oil pressure supply path, and a hydraulic reaction mechanism. The main hydraulic path supplies an oil pressure from a pump to a flow path switching valve connected to a power cylinder. The reactive oil pressure supply path branches from a portion of the main hydraulic path. The hydraulic reaction mechanism introduces part of the oil pressure, caused to diverge by the reactive oil pressure supply path, into a hydraulic reaction chamber for generating a steering reaction through a hydraulic reaction control valve mechanism controlled in accordance with the traveling conditions of a vehicle. A restriction smaller in diameter than the main hydraulic path is arranged between a branch portion branching from the main hydraulic path and the hydraulic reaction control valve mechanism, midway along the reactive oil pressure supply path.

A laser scanning microscope is capable of separating the fluorescence signals of different fluorophores in accurate unmixing realized by eliminating positional pixels shifts between different fluorescence images obtained through irradiation of different-wavelength laser lights. The microscope includes a laser light source capable of emitting a wavelength-changeable laser light, a correction amount determination unit that determines a correction amount for correcting an optical axis shift of the laser light, an optical axis adjusting unit that adjusts an optical axis, a scanning unit that performs two-dimensional scanning, an objective lens that focuses the laser scanning light to a specimen and fluorescence emitted from the specimen, a light detector that detects the fluorescence, and a control unit that changes the wavelength of the laser light synchronously with the scanning by the scanning unit while controlling the optical axis adjusting unit on the basis of the correction amount determined by correction amount determination unit.
摘要:
There is provided a steering device which allows the telescopic position of a movable column member to be steplessly adjusted, does not require a large force to operate a control lever for clamping, and prevents the movable column member from moving toward the vehicle front when a large impact force of a secondary collision is applied. The column clamp clamps by friction using wedges, making the movable column member position steplessly adjustable. The positive column clamp having the first and second toothed members clamps in steps defined by the engagement tooth pitch, so that the engagement between the first and second toothed members may be displaced. The swing lever attached to the second toothed member slides, guided by the swing center shaft, a distance equal to the engagement displacement along the axis of the first toothed member, enabling the second toothed member to correctly engage the first toothed member.

A steering column adjustable height and inclination of steering wheel has a singularity of control lever for controlling clamping/unclamping of a telescopic mechanism and a tilting mechanism for the adjustment. An energizing direction inverting mechanism inverts direction of biasing force applied to the lever by an energizing member from clamping direction to unclamping direction halfway through operation of the lever by a driver.

The universal joint of this invention comprises a hub interposed between an upper shaft and a middle shaft, an upper pin coupling together the upper shaft and the hub, a lower pin coupling together the middle shaft and the hub, and a stopper ring fitting over the outside of the middle shaft at an end thereof on the side of the upper shaft. The hub is formed in such a manner that the outer shape thereof is a spindle shape narrowing in the fore-and-aft direction with respect to the upper pin, and a bottomed hole provided with a taper portion is formed in the axial center thereof, opening towards the rear of the upper pin. In a front end portion of the upper shaft are formed a taper portion contracting towards the front of the upper pin and a groove portion engaging with the lower pin. The upper and lower pins are disposed adjacent to one another in the central axial direction of the hub and are also at a phase angle difference of, for example, 90 degrees. This invention provides a universal joint that has a simpler structure and a reduced manufacturing cost.

To provide a plasma generator having a plasma-generating zone of an increased volume.A plasma generator 100 has a casing 10 made of a sintered ceramic produced from alumina (Al2O3) as a raw material. The casing 10 has a slit-like gas intake section 12, and a gas discharge section 20 in which a plurality of holes are disposed in a line. From the gas intake section 12 to the top of a plasma-generating zone P, the slits have a width of 1 mm. There is provided a second gas discharge section 22 including holes 24 which have a diameter of 0.5 mm and a length of 16 mm and which are arranged in a line along the longitudinal axis of the plasma-generating zone P. The plasma-generating zone P has a cross-section which is a rectangle having a side of 2 to 5 mm. Electrodes 2a, 2b are provided with hollow portions on the surfaces thereof facing each other. A power sources supplies about 9 kV, which is obtained by boosting 100 V (60 Hz) and is applied to the electrodes 2a, 2b with a current of 20 mA. When argon gas is supplied through a gas intake section 12, a plasma was generated, even when the electrodes 2a, 2b were separated at a maximum spacing of 4 cm. No electric discharge was generated between the tips of the holes 24 and a treatment object.

A CPU executes a process for building an image, which is projected on three planes such as XY, YZ, and XZ planes mutually intersecting in three-dimensional space, of a three-dimensional image obtained by stacking in a direction of an optical axis a plurality of two-dimensional confocal images, which are obtained by changing the focal position of an objective lens against a sample in the direction of the optical axis of the objective lens. Then, a target region implemented by integrating pixels, whose points projected on the three planes are included in regions respectively specified for the three planes, among pixels configuring each of the two-dimensional confocal image.
