Patent EP-0561341-A2 (EP)
Inventor: CULP GORDON WALTER
IPC: H01L41/083
Filed: 1993-03-16
Abstract: The continuous bipolar mechanical output of a nonrectifying transducer is synthesized when the electrical segments 2 of a rectifying transducer are alternately switched into and out of a resonant loop in synchronism with polarity changes of the alternating drive signal. The known extraordinary transduction efficacy of a diverse class of rectifying transducer materials is thereby advantageously applied, while the known high electrical efficiency of resonance is also applied. Continuous bipolar transduction provides essential ingredients for the synthesis of nonsinusoidal mechanical output waveforms that afford extraordinary mechanical efficiency in a growing class of mechanical actuators, such as forcers, positioners and rubless walkers. Electrical resonance, in combination with nonsinusoidal mechanical waveforms, therefore provide a segmented rectifying transducer drive system of extraordinary efficacy.

Abstract: A method of testing an electronic apparatus (1) which eliminates a control signal line for setting an integrated circuit (IC1, IC2, IC3) to a test mode and a test mode select terminal of an external terminal section and wherein fetching of test data and transfer of the thus fetched test data are performed in an integrated operation. In each of the integrated circuits, a boundary scan control circuit (8) discriminates a category code (C i ) at the beginning of data inputted from a serial input terminal (SI) to control a pair of switching circuits (SW1, SW2). When the category code represents a test mode, predetermined terminals (b) of the switching circuits (SW1, SW2) are selected so that input data are sent out to boundary scan cells (BC1 to BC8). Fetching of parallel data from parallel input terminals (PI1 to PI4) and transfer to the boundary scan cells (BC5 to BC8) are performed at one time.

Abstract: A method is disclosed for removing oxide from the surface of a semiconductor body having a thick oxide and an adjoining nitride-covered thin oxide, without subjecting the surface to significant over-etching and thus avoiding degredation of the surface of the semiconductor body. The thick oxide is first etched for a period of time so that a portion of the thick oxide remains, and has a thickness comparable to that of the thin oxide. The nitride covering the thin oxide is next removed without appreciably etching either the remaining portion of the thick oxide or the thin oxide. Finally, the thin oxide and the remaining portion of the thick oxide are removed, without appreciably over-etching the surface of the semiconductor body.

Abstract: In a thermal print head (10), a partial glazed layer (13) has a width of 0. 1 to 0. 4 mm and a height of 15 to 25 µm. With the partial glazed layer (13) of this size, since the amount of accumulated heat is reduced, no trailing phenomenon would arise so as to improve the printing quality. It is also advantageous that no defective product will be manufactured because the glazed layer (13) is not too small, with less energy consumption. As a result, a high-quality printing operation can be maintained even during such high-speed printing as not exceeding 1 ms per one line.
