A work roll has a regularly and geometrically patterned uneven dulled section on the roll surface. Eavh uneven dulled section is composed of a crest and concavity and is of crater-like configuration. In order to obtain good performance in temper rolling, the crest is in a form of an annular ring extending around the edge of the concavity. According to the invention, pattern of arrangement of the uneven dulled sections is determined in relation to the diameter of the ring-shaped crests of the uneven dulled section so as to obtain optimum performance in producing good quality, exhibiting substantially high image clarify as coated by paint, enamel or so forth.

In a rear wheel steering vehicle equipped with a vehicle motion stability control system that can be selectively switched on and off, the motion stability of the vehicle is prevented from being impaired when an abnormal condition should develop to a rear wheel steering device of the vehicle. In addition to the rear wheel steering device, the vehicle is provided with an abnormal condition processing unit that turns on the vehicle motion stability control system upon detection of the abnormal condition of the rear wheel rear wheel steering device while the vehicle motion stability control system is turned off.

A rear wheel toe angle control device that ensures a stable steering performance even when the cornering powers of laterally opposing rear wheels are different from each other. When a reduction in the cornering power of one of the rear wheels owing to a drop in the tire pressure or a temporary tire is determined, a control unit changes the toe angle of the other rear wheel in a direction to increase the slip angle of thereof, and additionally changes the toe angle of the one rear wheel in a direction to decrease the slip angle of thereof. The combined cornering power of the two rear wheels is maintained at a normal level, and the steering performance of the turning vehicle remains the same. This also contributes to a stable running performance of the vehicle, and a maximization of the total available cornering power of the rear wheels.

An inner sealing portion seals a tubular port, which is provided to a receiver that receives water, at a first location of the tubular port. An outer sealing portion seals the tubular port at a second location of the tubular port spaced from the first location on an outer side of the inner sealing portion. A sealed space is formed between the inner sealing portion and the outer sealing portion. A tracer gas for performing a leak test of the outer sealing portion is enclosed in the sealed space. An amount of outwardly leaked tracer gas, which leaks from the sealed space through the outer sealing portion, is measured with a leak test device.

A bit image converter for composing a decoder for converting the value of counting clocks loaded in response to the width of bars or spaces for composing a bar code into character information of a code reader is composed of a module number calculator for calculating the magnification of the basic module from the number of the modules for composing one code unit (one character), a module number total comparator for comparing the total sum of the number of the calculated modules with a specified number n of the modules, a module number corrector for correcting, if the number of the calculated modules is less than the specified number n (n-1), it to the specified number n, and a bit image output unit. Thus, the code reader is adapted for a multilevel bar code system so composed that a result becomes correct information by correcting, if the number of modules for composing one character is less than a specified number n, it.

Disclosed is here a coordinate input apparatus in which light sources and light receiving elements opposing thereto with an input operation space therebetween are arranged in an X-axis direction and in an Y-axis direction. The light sources and said light receiving elements form a plurality of pairs and the light sources are sequentially driven to accomplish a scan operation. Coordinates corresponding to the light receiving element of which a light path is interrupted by a coordinate input scan in the input operation space are outputtted as detection signals and as coordinate input data of a position where the light path is interrupted. The apparatus includes a double-precision coordinate calculate unit for calculating, when light paths of two adjacent light receiving elements are simultaneously interrupted, coordinates of an intermediate point associated with coordinates corresponding to the two light receiving elements and a coordiante value correcting unit for achieving a parallax correction on the coordinates calculated by the double-precision calculate unit by use of a correction table.As an output from the coordinate correcting unit is converted into be coordinates corresponding to the arrangement constituted with the light sources and the light receiving elements so as to be outputted as coordinate input data.

A primary object of the present invention is to provide a remote control apparatus commonly usable to various devices, made in a smaller size and yet provided with no small area of the display portion for displaying operation status of the device. The invention provides a remote control apparatus using a touch panel, which is capable of sensing coordinates of a specified point for inputting the remote control command and also as a display of various images for inputting the operating command and of operation status of the remote controlled device. The invention also provides a remote control apparatus which puts a transmitting portion, receiving portion and image display control portion thereof in an enabled state for a predetermined period of time after the touch panel is pressed thereby to reduce power consumption.
