Title: Laminated piezo-electric element
Inventor: KAWAMURA YUKINORI
IPC: H01L41/22
Filed: 1990-09-17
Abstract: PURPOSE:To prevent the occurrence of chipping and cracks by performing chamfering on the edge sections of slits formed perpendicularly to the laminated direction on two parallel side faces of a laminated body built by alternately piling up piezo-electric material layers and internal electrode layers. CONSTITUTION:Slits of a prescribed depth are formed by machine work at positions which are not symmetfical with respect to the central axis of a laminated body on side faces of the laminated body symmetrical with respect to the central axis at every other internal electrode layers 2. Then edge sections of the slits are chamfered with sandpaper, etc. The chamfering is performed to a section 7 of about 0.1-0.2mm from the end of each edge and the angle of the edge sections is set at about 90 deg. or more on the side faces of the laminated body. Therefore, a highly reliable piezo-electric element which can maintain a stable expanding/contracting characteristic for a long period can be obtained, because the stress concentration which tends to be produced at the edge section of the slits can be relieved remarkably.

Title: Scrambling method
Inventor: SUGANO MASAKI
IPC: H04L9/16
Filed: 1984-11-21
Abstract: PURPOSE:To improve the privacy call performance and to judge the propriety of descrambling in real time by applying scrambling to 1-frame data including a scramble representing a pattern of plural scramble series by means of the scramble series in the preceding frame. CONSTITUTION:Transmission data is transmitt ed in the unit of one frame. One frame consists of a scramble code representing the pattern of the scramble series, a scramble synchronizing signal serving as a pilot signal detecting the propriety of descrambling and a frame synchronizing signal. The said code represents a pattern of the scramble series of the next frame. One of M series patterns is selected at each frame and the M series of the pattern is superimposed in the data scramble code and the scramble synchronizing signal. Thus, the data is not easily decoded even when the correspondence between the scramble code and the pattern is known.

Title: Method for thickly applying light accumulative substance
Inventor: YAMADA MASAHIKO
IPC: B05D5/06
Filed: 1986-10-17
Abstract: PURPOSE:To enhance light accumulation effect by providing a sufficient thickness on a coating surface by one coating work, by mixing a resin having high bonding strength and surface tension with a light accumulative substance. CONSTITUTION:For example, in thickly applying a light accumulative substance 1 to a plastic plate 4, the light accumulative substance 1 is mixed with an epoxy resin 2 to prepare a light accumulative resin 3 which is, in turn, applied to the plastic plate 4. The light accumulative resin 3 is certainly and thickly applied to the plastic plate 4 through the bonding strength and surface tension of the epoxy resin 2 by one coating. Since the content of the light accumulative substance per a unit coating area becomes high, light emitting capacity is high and visual confirming effect is enhanced. When the content of the light accumulative substance is made lower, the ratio of the epoxy resin becomes larger and the surface of the light accumulative resin 3 becomes smooth and the surface gloss thereof becomes excellent.
