摘要:
A surface acoustic wave apparatus includes three longitudinally-coupled-resonator-type interdigital transducers (IDTs) having a balanced-to-unbalanced conversion function, which are provided on a piezoelectric substrate in a direction in which a surface acoustic wave (SAW) propagates. Weighting is applied to at least one of the IDTs. For example, among the electrode fingers of the IDT located on the left side, an apodization-weighted electrode finger is provided for one of the electrode fingers positioned adjacent to the central IDT.

A surface acoustic wave filter device has a balance-unbalance conversion function and substantially equal input impedance and output impedance so as to increase out-of-passband attenuation. The surface acoustic wave filter device includes an unbalanced signal terminal, first and second balanced signal terminals, and first and second surface acoustic wave filters having input and output impedances. In each filter, one of the input and output impedances is approximately four times the other impedance. Additionally, 2n−1 first surface acoustic wave filters are connected between the unbalanced signal terminal and the first balanced signal terminal, and 2n−1 second surface acoustic wave filters are connected between the unbalanced signal terminal and the second balanced signal terminal, where n is an integer of 1 or more. The second surface acoustic wave filters are 180 degrees out-of-phase with respect to the first surface acoustic wave filters.

An overlay printing technique for use with a printing device is disclosed which enables multiple overlays to be defined for each the print page. Overlay data, overlay position information and overlay scale information for each of the overlays set up by an overlay set-up unit are transferred to an overlay storage unit by overlay transferring unit. Print processing unit expands overlay data stored in the overlay storage unit according to corresponding overlay position information and overlay scale information and prints the expanded data and print data obtained by expanding general print data for each print page. One or more overlays are placed in any positions within one print page which are determined by overlay position information and overlay scale information. For multiple-frame printing, a multiple-frame processing unit translates overlay position information and overlay scale information so that each overlay fits in a corresponding frame.

An instrument to remove stones from the human body such as stones in the gall bladder or kidney. An intracavitary tube is inserted in the organ where calculus is produced having an explosive charging chamber at the tip thereof. This explosive charging chamber is formed by a lid made of rigid material like metal except a fragile part made of less rigid materials and a triggering device for igniting the explosive from outside. The intracavitary tube is inserted into the organ, and the explosive charging chamber is brought near or in contact with the calculus, and then exploded to inflict a destructive force upon the calculus to crush it into small pieces, and the crushed small pieces are then eliminated from the human body.
摘要:
A direction of a dislocation line of a threading dislocation is aligned, and an angle between the direction of the dislocation line of the threading dislocation and a [0001]-orientation c-axis is equal to or smaller than 22.5 degrees. The threading dislocation having the dislocation line along with the [0001]-orientation c-axis is perpendicular to a direction of a dislocation line of a basal plane dislocation. Accordingly, the dislocation does not provide an extended dislocation on the c-face, so that a stacking fault is not generated. Thus, when an electric device is formed in a SiC single crystal substrate having the direction of the dislocation line of the threading dislocation, which is the [0001]-orientation c-axis, a SiC semiconductor device is obtained such that device characteristics are excellent without deterioration, and a manufacturing yield ration is improved.
摘要:
A fuel injection control system for an internal combustion engine is provided which is designed to perform pilot injection of fuel into the engine through a fuel injector prior to main injection. The system monitors a combustion state parameter representing a combustion state of the fuel within a combustion chamber of the engine which has been sprayed in the event of the pilot injection. When the combustion state parameter is determined as lying out of a stable combustion range where the fuel is to burn stably, the system changes the number of pilot injections to be executed prior to the main injection and/or the quantity of the fuel to be sprayed in each pilot injection, thereby enhancing the ignitability of the fuel in the pilot injection.
