    Abstract: A transversal SAW filter capable of reducing the effect of diffraction to achieve desired transmission characteristics without increasing the size of the surface wave substrate includes first and second IDTs arranged on a surface wave substrate so as to be spaced from each other by a predetermined distance. The first IDT has a plurality of impulses and the impulse in the 2n-th (n is a natural number) position counted from an impulse located at a maximum cross length in the 0-th position toward the second IDT has a magnitude which is equal to a magnitude of the (2n-1)-th impulse multiplied by -1.0.

    Abstract: Disclosed is a method for producing methacrolein, which comprises subjecting isobutylene and/or tert-butanol to gas phase catalytic oxidation with a molecular oxygen-containing gas in the presence of an oxide catalyst composition represented by the formula Mo.sub.12 Bi.sub.a Ce.sub.b K.sub.c A.sub.e B.sub.f O.sub.g, wherein A is Co solely, or a mixture of Co and Mg wherein the atomic ratio of Mg to Co is not more than 0.7, B is Rb, Cs or a mixture thereof, and a, b, c, d, e, f and g are, respectively, the specific atomic ratios of Bi, Ce, K, Fe, A, B and O, relative to 12 atoms of Mo. By the method of the present invention, it is possible to stably produce methacrolein in high yield, using an oxide catalyst composition which has a relatively simple structural composition and therefore can be easily prepared, and which has not only a prolonged catalyst life due to excellent thermal stability and reduction resistance, but also excellent selectivity for methacrolein, wherein the catalyst composition contains Bi, Ce, K and Fe in specific amounts and in a specific relative amount ratio, and does not contain such elements as cause environmental pollution and toxicity problems, and also does not require the use, as raw materials for the preparation thereof, compounds having low solubility in water, such as compounds of W, Sb and Nb, which exhibit desired catalytic performances but are disadvantageous because of difficulties in obtaining uniform catalyst compositions.

    Abstract: An exposure mask having an excellent alignment accuracy between patterns, which is prepared by first forming on a light transmissive substrate a light shielding film or a semi-transparent film pattern (first pattern) somewhat larger than a desired dimension, forming thereon a semi-transparent film or a light transmissive film pattern (second pattern) so as to include all patterns of the desired dimensions made up of a light shielding part, a semi-transparent part and a light transmissive part, and then removing a projected part of the first pattern with use of the second pattern as a mask.The semi-transparent film is formed of at least two layers each of which contains a common element, thus the semi-transparent film can be made with use of the same apparatus and when patterning, etching process can be carried out with use of the same etchant.Further, since in a mask including the semi-transparent pattern, at least that area of a non-pattern zone where light reaches a wafer through the transfer, acts to shield the exposure light, too narrowed pattern or insufficient focal depth can be prevented.

    Abstract: A photoresist pattern is formed on a quartz substrate. The quartz substrate is dipped into a silicon oxide supersaturated solution of hydrofluoric acid, and a silicon oxide is precipitated out of the supersaturated solution, thereby forming an SiO.sub.2 film on that exposed surface of the quartz substrate which is not covered with the photoresist pattern. After that, the photoresist pattern is ashed by oxygen plasma, and the ashed pattern is removed. The SiO.sub.2 film remaining on the quartz substrate serves as a phase shifter.

    Abstract: The invention is directed to a hydraulic braking system having a master cylinder (10) in which a first piston and a second piston are slidably disposed to define a first pressure chamber (11) and a second pressure chamber (12). A valve device (24) is provided between the first pressure chamber and a reservoir (20). A first pressure control device (30, 31) is provided between the first pressure chamber and wheel cylinders (38, 39), and a second pressure control device (32, 33) is provided between the second pressure chamber and wheel cylinders (40, 41). A pump (27) is provided in a passage connecting the reservoir and the first pressure control device, and driven to supply a brake pressure from the former to the latter. When the valve device is actuated to block the communication between the first pressure chamber and the reservoir, and the pump is driven, the pressure in the first pressure chamber will be increased to move the second piston, so that the pressure in the second pressure chamber will be increased. Accordingly, the pressure in each wheel cylinder may be controlled by the first or second pressure control device without depressing the brake pedal.

    Abstract: An apparatus is provided for producing a dough roll by rolling up a dough piece. The apparatus has a moving means that includes a holding roller and an endless belt supply device, and a rolling up mechanism having upper and lower endless belt devices. The belt of the upper endless belt device moves rearwardly, and the belt of the lower endless belt device moves forwardly at a speed higher than that of the upper endless belt device. When a dough piece is fed to the apparatus the leading end begins to be rolled at the upstream ends of the upper and lower endless belt devices while its trailing end stays between the belt of the endless belt supply device and the holding roller. Therefore, the leading end moves at a speed which equals the difference between the speeds of the upper and lower endless belt devices while the trailing end moves at the same moving speed as that of the belt of the endless belt supply device. By controlling the relation of the speeds of these endless belt devices, the dough piece is stretched to have a desired length in the feeding direction. When the dough piece is rolled, a dough roll having a desired number of layers can be produced.
