A rope substitution belt which has a higher strength than a rope having the same mass, has a substantially circular section, and is equipped with belt portions for sewing on both sides. The belt is a narrow width woven fabric (10) including warps (6) and wefts (7) of synthetic fiber filaments. The belt includes a main body portion (2), a belt portion (4) and a connecting portion (3) for connecting the main body portion (2) to the belt portion (4), that are disposed in a longitudinal direction. The main body portion (2) has a structure with wadding yarns (5) which are woven into a hollow woven structure. The warp density coefficient in the hollow woven structure portion (22) is set to be not greater than 0.700. The belt portion (4) has a structure with a part, or the whole, of the wadding yarns (5) which are so arranged as to cross the wefts with the warps (6) of the hollow woven structure of the main body portion (2). The belt portion (4) has a width W which is at least 2.0 times the width W of the main body portion (2). The connecting portion (3) is constituted such that while the width is gradually changed, it step-wise shifts over a plurality of stages to the woven structure of the main body portion (2) or the belt portion (4).
摘要:
In an electrophotographic system, an electrostatic latent image as formed on a photoreceptor is developed with a developing agent to form a toner image thereon, a transfer paper is laid over the toner image and pressure is applied to the photoreceptor and the transfer paper so as to transfer or simultaneously transfer and fix the toner image onto the transfer paper. The photoreceptor is one having a surface protecting layer and a light-sensitive layer made of a hydrogenated and/or fluorinated amorphous silicon. The light-sensitive layer and the surface protecting layer of the photoreceptor are uniformly heated to a constant temperature. A charging device or a discharging brush or blade is used as a device of discharging the charges of the photoreceptor after the transference.

A single-crystal substrate is prepared which has the (100) crystal plane with a step line formed therein by cleaving an MgO single crystal. By evaporating metal onto the cleavage plane, with a mask wire of platinum disposed at a distance from the cleavage plane and extended in a direction across the step line, a pair of metal thin film electrodes separated by a gap are epitaxially grown. By this, a step line corresponding to the cleavage-plane step line is formed in the surface of each of the metal thin film electrodes. Metal is further evaporated onto the metal thin film electrodes at a low rate, by which nano-size thin wires extending along the step lines are grown so that they approach each other and are finally connected to each other.
摘要:
An apparatus for calculating vehicle-wheel revolution estimated values detects parameters such as the number of vehicle-wheel revolutions and vehicle-wheel revolution speeds, detects differences between the previous estimated values and the detected parameters or other parameters such as vehicle-wheel revolution speeds and accelerations calculated from the detected parameters, stores the differences at a predetermined rate, determines variations, and updates the estimated values based on the determined variations. Since the variations are determined so that the increase rate of the variations decreases as the accumulated values of the differences increase, lag time is minimized and at the same time noise is eliminated, thus precisely estimating the revolution values of the vehicle wheels. Antiskid control, traction control, and other controls can be effectively executed by using the estimated values even when the vehicle wheels move vertically on rough road surfaces or even when the vehicle wheels are eccentric. Consequently, the braking distance can be reduced, and the braking effects and the durability of control units are enhanced.

In an internal combustion engine, inside an engine exhaust passage, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged. The carrier (50) of the exhaust purification catalyst (13) is formed from a crystallized composite oxide of aluminum and an alkali earth metal. On this carrier (50), precious metal catalysts (51, 52) are carried. The concentration of hydrocarbons which flow into the exhaust purification catalyst (13) is made to vibrate by within a predetermined range of amplitude of a 200 ppm or more and within a predetermined range of period of 5 second or less, whereby the NOx which is contained in exhaust gas is reduced at the exhaust purification catalyst (13).

Disclosed is an exhaust gas purifying catalyst in which grain growth of a noble metal particle supported on a support is suppressed. Also disclosed is a production process for producing an exhaust gas purifying catalyst. The exhaust gas purifying catalyst comprises a crystalline metal oxide support and a noble metal particle supported on the support, wherein the noble metal particle is epitaxially grown on the support, and wherein the noble metal particle is dispersed and supported on the outer and inner surfaces of the support. The process for producing an exhaust gas purifying catalyst comprises masking, in a solution, at least a part of the surface of a crystalline metal oxide support by a masking agent, introducing the support into a noble metal-containing solution containing a noble metal, and drying and firing the support and the noble metal-containing solution to support the noble metal on the support.
