Abstract: A substrate polishing apparatus is provided for preventing excessive polishing and insufficient polishing, and enabling a quantitative setting of an additional polishing time. The substrate polishing apparatus comprises a mechanism for polishing a substrate to be polished; a film thickness measuring device for measuring the thickness of a thin film deposited on the substrate; an interface for entering a target thickness for the polished thin film; a storage area for preserving past polishing results; and a processing unit for calculating a polishing time and a polishing rate. The substrate polishing apparatus builds an additional polishing database for storing data acquired from the result of additional polishing in the storage area.

Abstract: A method for reproducing a low noise signal for a solid state imaging device which can reduce not only the reset noise but the amplifier noise around frequency zero, avoiding the saturation of the voltage conversion part in a bright scene, is accomplished by controlling a reset pulse of a CCD imaging device according to the result of comparing the output signal of the CCD imaging device with a reference signal value. When the output signal of the CCD imaging device is smaller than the reference signal value, the reset pulse is not applied to the CCD imaging device. Thereat, a pixel signal is reproduced as a differential signal between two signals sampled at two points with an interval of T0, the amplifier noise around frequency zero being reduced in the pixel signals.

Abstract: A gap control device which is configured for use with a laser welding device adapted to weld objects to each other is provided. A laser guide is configured to guide a laser beam to a focusing position. A gap holder is configured to feed the objects in a feeding direction toward the focusing position and to form a predetermined gap between the objects at at least a part of the focusing position. A press is configured to press the object materials at a pressing position which is distant from the focusing position by a predetermined distance in the feeding direction.

Abstract: A punch for forming a die-cut pattern in a sheet inserted into a slit includes a punch cutter and a base having a wall portion with which the sheet comes in contact, the wall portion being constituted of a rear wall portion extending from a frontal center portion to one side of the punch and an inclined wall portion extending rearward to the other side at of the punch an angle of 45 degrees with respect to a line extending from the rear wall portion. In the slit, a first positioning member having a ruler portion extending to one side and a second positioning member having a ruler portion extending to the other side are installed so that the ruler portions are each turnable around the punch cutter positioned therebetween.

Abstract: A punch assisting apparatus usable in combination with one of a plurality of punches includes an apparatus base and a handle pivotably attached to the apparatus base, the apparatus base being provided with a punch holder integrated therein which allows the plurality of punches having different sizes to be independently positioned and fixed in accordance with their respective sizes. The punch holder is configured so as to provide both a use position and a nonuse position by changing its posture; whereby, when a punch is mounted to the punch assisting apparatus to replace the one previously mounted, the punch can always be positioned at a given position regardless of the type of punch. Since the punch assisting apparatus is provided with a punch holder combined in one piece, the punch assisting apparatus and punch holder can always be handled together, which makes managing them easier.

Abstract: In a cutting device 1 for cutting a sheet material by moving a cutting tool along a rail provided at a template, the cutting tool is configured such that a cutting blade and guide portions engaged with the rail are provided on a disc face of a rotary disc, and the rotary disc is rotatably mounted to a grasping portion. When the guide portion is engaged with the rail, the rotary disc is naturally rotated while being guided by the curved rail, and the cutting blade provided at the rotary disc is naturally oriented in the same direction as the rail.

Abstract: A merchandise display implement used while being hooked on a frame bar, including an opening portion capable of housing merchandise in a condition of rowing the same, a hanger portion to be hooked on the frame bar, and a supporting leg capable of being mounted on a plane surface is constructed. Even though a shelf or a board is not provided, the merchandise can be displayed in a plane-surface manner when only the frame bar is installed on a wall in a shop. Further, since the merchandise can also be mounted on a plane surface by a supporting leg, the merchandise can also be displayed on a board, a shelf, or the like. Furthermore, only by engaging a hook with a hook engaging hole, the merchandise can also be displayed in a condition in which a plurality of merchandise display implements is connected to each other.

Abstract: A method for producing interpolated signal values between sampled signal values in a sampled image signal produced by a checkerboard sampling pattern is accomplished by extracting a block of 2N-by-2N signal values that correspond to a block of sampling locations of the checkerboard sampling pattern, providing a set of frequency coefficients by a discrete cosine transform with the block of 2N-by-2N signal values, and providing at least a interpolated signal value that corresponds to the interpolation location by an inverse discrete cosine transform with the set of frequency coefficients. Here, a block of 2N-by-2N signal values is extracted so that sampled signal values exist in all the pixel locations of the block.
