A device for narrowing the breadth of a sheet spring material in an apparatus for manufacturing a taper leaf spring by which the sheet spring is previously subjected to breadth narrowing operation with edge rollers before taper rolling.A shape for narrowing the breadth of a sheet spring material is calculated so that a product after rolling may be within the tolerance. Then, a shape of template thus obtained is detected by a pair of detecting rollers to regulate the interval between the work rollers automatically before taper rolling.

In an apparatus for manufacturing a taper leaf spring, by which after performing rolling on the edges of a sheet spring material in the direction of its breadth, rolling for tapering the sheet in the direction of its thickness is carried out, an edge roll assembly is employed for the sake of rolling in the breadth direction. In the edge roll assembly, constraining flanges for regulating the sheet thickness are provided on both ends of the main body of the edge roll so that expansion of both sides of a sheet spring material in the sheet thickness direction due to the effect of rolling in the sheet breadth direction is suppressed by the flanges and the thickness of a sheet spring material is kept uniform as a whole prior to performing rolling in the sheet thickness direction.

A process of manufacturing a taper leaf spring by which rollers for measuring the length and the thickness are respectively disposed on the take-out side of a material plate for a taper leaf spring relative to a pair of rolling rollers, and also rollers for measuring the breadth are disposed on the same take-out side; rolling for regulating the breadth is beforehand performed by a pair of edge rollers on the take-in side of the material plate relative to the pair of rolling rollers; the distance of the interval between both rolling rollers is adjusted by comparing signals coming from the rollers for measuring the length and the thickness with the standard signals based on the predetermined specifications of the length and the thickness; the regulation of the breadth by means of the pair of edge rollers is controlled by comparing the signal from the breadth measuring rollers with the standard signal based on the predetermined specification; so that the material plate is rolled to a taper as desired.

LEDs (7) are arranged on at least opposite two corners of a bottom surface of a box body (11) of a tray shape whose bottom surface is quadrilateral, whose upper side is open, on an inner surface of which a light reflection member (11b) is provided, and whose side walls (11c) are inclined outward, so as to irradiate inside of the box body, wherein a plurality of LEDs (71) are arranged so that a region irradiated by each of the LEDs (71) rotates sequentially in a specific direction (same direction). As a result, there can be obtained a surface light source having high brightness and uniformity in an arbitrary size whether the light source is small or large while using semiconductor light emitting devices (LEDs), and an electrically illuminated signboard using the surface light source, which is thin and capable of uniform display and which operates with low electricity consumption.

A belt device includes a belt as an endless belt that has a scale with a large number of scale marks formed along the whole circumference of the belt. A sensor reads the scale to obtain scale information. A control device provides control to correct a belt speed, based on scale information read. A scale-mark degradation determining unit determines whether the scale mark is degraded. A belt drive controller continuously provides control to correct the belt speed for a degraded portion until the scale-mark degradation determining unit determines that there is no degradation.

In an image reading device having a sheet-through mechanism, a controller controls a stepping motor to decelerate an image reading system when the image reading system is moved to a reference white plate reading position, and controls a stepping motor drive electric current to decrease when the image reading system reads a reference white plate. When the image reading system finishes reading the reference white plate, the controller controls the stepping motor drive electric current to increase so as to rapidly decelerate the image reading system. The controller further controls the stepping motor such that a moving speed of the image reading system to an original document reading position is lower than a moving speed of the image reading system to the reference white plate reading position.

The present invention provides an architectural material obtained by forming a decorative layer containing calcium carbonate as a binder component on the surface of a base material, and laminating a ventilating protective sheet having a peeling strength of 200 to 4000 mN on the surface of the decorative layer without interposing an adhesive layer separately, and a process for producing the architectural material. The architectural material has excellent soiling resistance or abrasion resistance, and is highly practical.

An image forming apparatus has an image scanner, a sensor for determining that the image sensor has scanned the front edge of a document, and a controller using main scanning line synchronizing signals and an output signal of the sensor as reference signals. In response to the reference signals, the controller causes at least a writing unit to start writing each image data of particular color and causes a transfer medium driving circuit to start driving a transfer medium. The apparatus allows image components of different colors to be transferred to the transfer medium one above the other in accurate registration.

A device for regenerating a sheet-like recoding medium which feeds a printed sheet-like recording medium. A regenerating treatment unit eliminates a image formed on the recording medium. The recording medium is then discriminated and separated based on whether the regenerated recording medium is reusable or not and whether the regenerated recording medium is to be treated again by the regenerating treatment unit, and a storing unit stores the separated reusable recording medium. Further, a control section controls the regenerating treatment unit to treat the regenerated recording medium again when the regenerated recording medium is judged to be treated again by the regenerating treatment unit.
