Filed: 1986-11-27
Abstract: PURPOSE:To improve the transmission efficiency of ultrasonic waves by forming an outer surface, to which at least ultrasonic vibrations are applied directly, under a satin state. CONSTITUTION:A tabular upper surface plate 18 is moved in the direction of the arrow 19 under the state in which a chip 1 is held and pressed at pressure such as 1-7kgf by a platform-shaped lower surface plate 17 and the upper surface plate 18 consisting of Si3N4, SiC, ZrO2, etc. Abrasives 20 in which powdered diamond abrasive grains are mxied in a pasty state are positioned previously onto the lower surface plate 17 at that time. The grain size of diamond abrasive grains is approximately decuple as large as desired roughness. Consequently, the chip 1 is rolled through abrasives 20 on the lower surface plate 17. Accordingly, an outer circumferential surface 16 is polished into a satin state by abrasives 20. The outer Circumferential surface 16 of a section to be held 3 is brought to the satin state in the chip 1, thus improving the transmission efficiency of ultrasonic waves through a bonding-arm 2.

Title: Speaker edge
Inventor: KOURA TETSUJI
IPC: H04R7/20
Filed: 1991-10-28
Abstract: PURPOSE:To improve the acoustic characteristic by dividing a circular part in the circular direction and alternately changing the width or material. CONSTITUTION:The intensity of the circular part divided in the circular direction of the edge is alternately changed, and a part with low edge intensity in the ample amplitude is changed in the amplitude direction. On the other hand, a part with high edge intensity functions as a base material, which is pinched between parts with low intensity, and it is less necessary to shift in the circular direction to enable ample displacement in the amplitude direction, resulting in providing the superior linearity in power/displacement characteristic. Thus, the edge for speaker with less distortion on acoustic characteristic can be realized.

Abstract: PURPOSE:To reduce the diffusion component of excess charge collected in a memory region, and improve the resistance to soft error of a memory device, by arranging an inversely biased P-N junction region below a information storage region storing information. CONSTITUTION:In the lower part of a source region 9, a drain region 10 and a capacitance electrode 11 on a P-type substrate 1, an N-type impurity region 2 of high concentration is formed.

Via polycrystalline silicon 5, a positive bias voltage is applied to the above diffusion layer 2, in order to form a depletion layer in the vicinity of the diffusion layer. Thus the P-N junction is inversely biased. Thereby the diffusion component of excess charge collected in the memory region is remarkably reduced, so that the resistance to soft error is improved.
