Patent JP-H08172337-A (JP)
Title: Surface acoustic wave filter
Inventor: WATANABE TORU
IPC: H03H9/64
Filed: 1994-12-20
Abstract: PURPOSE: To reduce the influence of a diffraction loss and to secure required transmission characteristics without increasing the size of a surface acoustic wave substrate by setting up a 2n-th impulse to a value obtained by multiplying the value of a (2n-1)th impulse by a specific value. CONSTITUTION: A 1st inter-digital transducer(IDT) 24 and a 2nd IDT 25 are arranged on a surface acoustic wave substrate with a prescribed distance. When impulse 26 corresponding to maximum cross width is set up as 0 order impulse in a pulse string from the IDT 24, a 2nd impulse out of impulse elements 27 to 34 arranged from the impulse 26 to the side of the 2nd IDT 25 is set up to a value obtained by multiplying the value of the (2n-1)th impulse by (-1.0). Thereby one-end of the impulse elements 17 to 34, i.e., the upper end in the figure, is aligned to the upper end of the impulse 26. When the IDT 25 is set up as an input side IDT, a diffraction loss at the time of propagating a surface acoustic wave excited by the IDT 25 to the IDT 24 can be reduced and a transmission characteristic itself is not sharply reduced.

Title: Regeneration of eustoma plant and proliferation of seedlings thereof
Inventor: SHIMIZU JUNICHI
IPC: A01H4/00
Filed: 1988-12-19
Abstract: PURPOSE:To accomplish sure regeneration of the title plant in a short time in high efficiency by a method wherein callus is induced from the tissue pieces of a Eustoma plant, and the callus is then put to culture to differentiate indefinite buds followed by culture of the buds to form seedlings. CONSTITUTION:Seeds of a Eustoma plant (e.g. Eustoma grandiflorum) are sterilized and put to culture in a solid medium into seed seedlings. The tissue pieces prepared by finely chopping the stem/leaf parts of said seedlings are put to culture in a solid medium to induce callus. Thence, the callus is transplanted to a second solid medium to make a culture to effect differentiation of indefinite buds, which are then taken out using e.g. a forceps and transplanted to a third medium to make a culture individually to effect root generation, thus regenerating the objective seedlings. Furthermore, the seedlings can be proliferated by assimilation.

Title: Waste-heat recovery water-tube boiler
Inventor: NAKAMURA SUNAO
IPC: F23D14/16
Filed: 1994-12-21
Abstract: PURPOSE: To lower the temperature of the flame so as to reduce NOX from the combustion by combining surface combustion using a metallic fiber-sintered mat with heating of premixed fuel gas using an exhaust-gas heat exchanger. CONSTITUTION: As regards a heat exchanger 3 metal fiber-sintered mat 3d is partitioned off by a partition 3c into a first region 3a for premixed fuel gas to flow through and a second region 3b for the exhaust gas from combustion to flow through. Integrally on the downstream side of the first region 3a a burner part 2 is formed with the surface part of the first region 3a as a combustion area 2a. The exhaust gas, after passage through the second region 3b, is partly incorporated with a flow of premixed fuel gas by the action of a blower 9 and carried though the first region 3a of the heat exchanger part. In the first region 3a, with heat energy transferred from the metallic fiber formed in a fiber mat, the premixed fuel gas is heated to a high temperature and then burns at the combustion area 2a, which is the downstream surface part of the first region 3a.  The fuel fed for this combustion is limited to an amount necessary for making the surface of the metallic fiber-sintered mat red-hot and for the evolution of adequate radiant heat. Therefore, the temperature of the flame can be made low and NOX in the exhaust gas can be reduced.

Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To reduce the layout area of a building block type semiconductor integrated circuit by reducing the areas of functional blocks and wiring channels at the time of designing the layout of the circuit. SOLUTION: When three kinds of contact cells respectively having square, rectangular, and crisscross contact margins are used around a contact hole in a method for designing layout of semiconductor integrated circuit, larger costs are successively added in the order of the contact cells having the horizontal rectangular shape, crisscross shape, square shape, and vertical rectangular shape, namely, in the order of the heights of the cells in step 4000. In the next step 4001, the contact cell having the horizontal rectangular shape and the lowest cost is selected and whether or not the selected contact cell meets a design rule is checked. When it is discriminated that the selected cell does not meet the design rule in step 4003, the process returns to the step 4001 to select another contact cell having the next lowest cost. After the selection, the process proceeds to the step 4003.  In such a way, the steps 4001 and 4003 are repeatedly performed until a suitable contact cell is selected.
