A line buffer unit stores the pixel values of image data for respective lines in synchronism with pixel clocks and a horizontal sync signal. An output counter generates a coordinate value to specify a pixel position in second image data based on the count value of predetermined clocks and the horizontal sync signal, and a data request unit converts the generated coordinate value into a pixel position in input image data on the basis of the set scale value. The pixel values of pixels required for arithmetic operations are acquired from the line buffer unit based on this pixel position, and an arithmetic unit calculates the pixel value of a pixel corresponding to the coordinate value. When the arithmetic unit is not ready to execute the arithmetic operation of the pixel value, generation of the coordinate value by the counter is stopped until the arithmetic unit is ready to execute the operation.

The present invention is to efficiently and simply prepare an optically active 7-substituted-2-aminotetralin with industrial advantage. In the process, a 7-substituted-2-tetralone or its bisulfite adduct is reduced with a microorganism to an optically active 7-substituted-2-tetralol. Then, a sulfonyl group is introduced to the hydroxy group to form an optically active 7-substituted-2-sulfonyloxytetralin. Then, with inversion of the configuration, a nitrogen substituent is introduced using a nitrogen nucleophile to form an optically active 2,7-substituted tetralin. Furthermore, if necessary, the nitrogen substituent is converted into a non-substituted amino group. Thus, an optically active 7-substituted-2-aminotetralin or its salt is prepared.

In order to obtain a plane lattice hollow concrete slab having a high workability and a high sound insulating property, and a cross arm brace used in the plane lattice hollow concrete slab, the plane lattice hollow concrete slab comprises a light weight body 5 buried in a small space 4 which is partitioned on a grid by upper reinforcing bars 3a and 3b and lower reinforcing bars 2a and 2b positioned on a grid in a slab. The light weight body is a solid-core or a hollow light weight ball body. The light weight body has a diameter which passes through a top surface of the small space and which does not pass through a side surface of the small space. The light weight body is fixed to a predetermined position by a cross arm brace which is positioned on the upper reinforcing bar. The cross arm brace comprises at least two auxiliary reinforcing bars positioned in parallel between upper reinforcing bars adjacent to each other, and a plurality of units each of which is fixed downwardly on the auxiliary reinforcing bar. Each of the units is inserted into a small space formed by upper reinforcing bars which are positioned on a grid. A light weight ball body is fixed to a predetermined position of the small space.

A wet paper web transfer belt comprises a base body, a wet paper web side layer, and a machine side layer. The wet paper web side layer is formed of a high molecular weight elastic section, and fibers and filler particles are exposed at its surface. The fibers and filler particles are exposed in the form of an island-sea structure comprising islands section where the fibers are exposed, and a sea section where the filler particles are exposed. The fibers and the filler particles, both exposed at the wet paper web side layer, hold water at different times in the papermaking process as the wet paper web moves out of the press part of the papermaking machine.
摘要:
The duplexer includes a transmit filter connected between an antenna terminal and a transmit terminal, and a splitter circuit and a receive filter connected in series between the antenna terminal and the receive terminal. The splitter circuit includes at least one phaseline connected between the antenna terminal and the receive filter and at least one resonator connected in parallel with the phaseline. According to the present invention, the length of the phaseline can be made shorter, so the entire duplexer can be made more compact in size. In addition, an inductors are preferably connected between each ends of the phaseline and the resonator. In this case, the inductance of a wire or via formed within the package can be used.

摘要:
In a photosensitive material processing apparatus of the present invention, a brush roller used in a pre-water-washing section and a developing section is formed by winding a slender band wherein bristles are woven into a knitted fabric onto the peripheral surface of a roller which is a core member. This makes it possible to arrange the bristles closely and uniformly on the whole of the peripheral surface of the roller. Therefore, the brush roller can be applied to a photopolymer plate, which uses a non-polymerizable layer as a photosensitive layer and requires strong rubbing without causing brushing unevenness.

A printing sheet can be easily peeled from a base film. A printing sheet can be easily and efficiently mounted on an appliance. It includes a base film as a base material, an adhesive applied on the surface of the base material, and a main body film adhered to the base material through the adhesive. The main body film may be peeled from the adhesive and base material. The main body film has a plurality of printing sheets, and each printing sheet of the printing sheets has a half-cut portion cutting off only the printing sheet without cutting off the base material, so that each printing sheet may be peeled from the adhesive and base material. Preferably, the base film has a greater thickness than the main body film. The half-cut portion has an end portion in a state being lifted from the base material having the adhesive.
