摘要： A transversally coupled double-mode SAW filter using a surface acoustic wave has two SAW resonators which have curtain-like electrodes and a pair of reflectors on both side thereof, respectively, and which are disposed in parallel on a piezoelectric flat plate in the propagation direction of the surface acoustic wave. The curtain-like electrodes of the SAW resonators have a first bus bar of electrically positive electrode which extends in the propagation direction of SAW and second and third bus bars of electrically negative electrode which extend in parallel on both sides of the first bus bar. The first bus bar has multiple electrode fingers of electrically positive electrode which face the second and third bus bars on both sides thereof and which extend in a direction perpendicular to the propagation direction of SAW so as to suitably have a space of &lgr;/2, &lgr; being the wavelength of the surface acoustic wave, and a width of &lgr;/4. The second and third bus bars have multiple electrode fingers of electrically negative electrode which correspond to the electrode fingers of electrically positive electrode, face the first bus bar and extend in a direction perpendicular to the propagation direction of SAW so as to similarly have a space of &lgr;/2 and a width of &lgr;/4. Thereby, the curtain-like electrodes are constituted to invert the direction of driving field by 180° with the first bus bar therebetween, and to enable making the passband width sharply broader than before by use of the frequency difference between excited primary symmetric mode and primary anti-symmetric mode.

摘要： A multilayer circuit board for holding a flip chip thereon includes laminated first to fourth substrates. A first pattern integrated portion having a locally high pattern density is provided on the second substrate. Further, on the fourth substrate which is disposed on an opposite side of the second substrate with respect to a center in a laminated direction of the circuit board, a second pattern integrated portion having a locally high pattern density is disposed to correspond to the first pattern integrated portion. Accordingly, a local warp can be prevented from being produced on the mounting surface of the multilayer circuit board when the circuit board is manufactured by baking.

摘要： Herein disclosed is a semiconductor memory device, in which peripheral circuits are arranged in a cross area of a semiconductor chip composed of the longitudinal center portions and the transverse center portions, and in which memory arrays are arranged in the four regions which are divided by the cross area. Thanks to this structure in which the peripheral circuits are arranged at the center portion of the chip, the longest signal transmission paths can be shortened to about one half of the chip size to speed up the DRAM which is intended to have a large storage capacity.

摘要： As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the "Lead-On-Chip" or "Chip-On-Lead" structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

摘要： Herein disclosed is a semiconductor memory device, in which peripheral circuits are arranged in a cross area of a semiconductor chip composed of the longitudinal center portions and the transverse center portions, and in which memory arrays are arranged in the four regions which are divided by the cross area. Thanks to this structure in which the peripheral circuits are arranged at the center portion of the chip, the longest signal transmission paths can be shortened to about one half of the chip size to speed up the DRAM which is intended to have a large storage capacity.

摘要： Coil springs 96 and 97 are incorporated in a driving-side transmission mechanism 61 so as to absorb backlashes between a rack 55 and a drive gear 59a. Since the respective backlashes between the drive gear 59a and the rack 55 are absorbed by way of the coil springs 96 and 97, merely phase matching at the sole driving-side transmission mechanism 61 is required as phase matching work of toothed portions of gears during assembly, thereby simplifying the assembling task and shortening assembly time. Additionally, since a coil spring is not included in the rack 55, the rack can be designed to be small-sized in its width direction, thereby minimizing the moment of a force about the meshed engagement point, acting on an optical head carriage 53, and reducing transfer loss in the head.

摘要： A masking paper is wound in a roll form and includes a relatively thin synthetic resin film folded in a plurality of parallel pleats and a relatively thick tape disposed along a longitudinal margin of the film and having a pressure sensitive adhesive layer formed on the opposite sides thereof. An apparatus for applying and dispensing the masking paper includes a housing accommodating the masking paper in a roll form, a group of rolls for taking the masking paper out of the housing and a cutter blade for cutting the masking paper. The cutter blade is reciprocated back and forth across the masking paper, and is retracted from the masking paper during its movement from a starting position.

摘要： A portable, cordless battery-powered tool with a relatively small overall length is provided. A handle section forms the rearmost part of the tool. An electric motor is located below a spindle and forwardly of the handle section. The motor has a rotatable shaft located in parallel with the spindle. The handle section is provided with a switch trigger which is substantially aligned with the central axis of the spindle at its top.
