Abstract: PURPOSE:To soften even a heat resistant plastic film to the extent enough for shaping and consequently make the formation of precision embossing possible by a method wherein both rolls are made of metal so as to heat the plastic film up to elevated temperature. CONSTITUTION:A pair of metal rolls having plates, which are in positive plate to negative plate with respect to embossed pattern or in opposing which their depressing and raising relationships are opposite to each other and which correspond to each other in the relationship engaging with each other, are used by synchronously combining the embossed patterns with each other. Plastic film 1 is roll-pressed between both the rolls, which are brought under heated state, so as to emboss the film 1. As the metal rolls 2 and 3, chromium-plated copper rolls are preferably used from the view point of high durability. The heating temperatures of the rolls depend on the plastic film used. In general, the temperature of the positive plate roll lies within the range of 100-200 deg.C, while that of the negative plate roll lines within the range of 80-180 deg.C. As the heat resistant plastic film, polyethylene terephthalate or the like is exampled.

Title: Radio communication system
Inventor: OZAWA KAZUYOSHI
IPC: H04L1/00
Filed: 1993-01-29
Abstract: PURPOSE:To provide a radio communication system for properly transmitting a target bit sequence even at the time of retransmission even when a partial carrier frequency disables communication by the influence of frequency selection fading or the like. CONSTITUTION:A transmission source radio terminal receiving a retransmission request packet from a destination radio terminal generates a retransmission packet by judging the bit sequence to be retransmitted from retransmission request carrier information in the same packet and sends it to a reception radio terminal by using the communication enable carrier frequency judged from normal reception carrier information. At such a time, when there is one bit sequence to be retransmitted, the transmission source radio terminal parallelly sends the retransmission packets by using all the communication enable carrier frequencies. When there are two bit sequence to be retransmitted and there is one communication enable carrier frequency, these bit sequences are sent while being divided twice by using one communication enable carrier frequency.

Title: Butt welding method using backing strip for part where bending effect acts
Inventor: UCHIDA MASAKATSU
IPC: B23K9/035
Filed: 1981-02-04
Abstract: PURPOSE:To prevent generation of cracking in a weld zone by applying a backing strip having a groove of a specific shape along the butt part of a pair of base metals and welding these. CONSTITUTION:A backing strip (d) is applied along the butt part (c) of a pair of base metals (a), (b), and these are welded from the front side. The strip (d) consists of the same kind of metal as that of the metals (a), (b), and has a groove (e) suited for a groove shape along its longitudinal direction. Both side edges(l) (m) of the groove (e) are positioned on the rear surfaces (f), (g) of the base metals (a), (b) by leaving a distance (p) cnsisting of a root leading end (j). If these are welded with weld metal (j), the lower part at the leading end (j) of the root part is a space and therefore the molten metal is easy to penetrate there and penetrates into the backing strip (d) of the same metal as the base metals (a), (b). Since both side edges(l), (m) of the groove (e) of the backing strip (d) contact tightly with the rear surfaces of the base metals (a), (f) by leaving certain distance (p) from the leading end (j) of the root, s dpsvr (o) is created after welding. When a bending deformation occurs by the action of bending effect, the leading ends of the slits on the tight adhesion surfaces of the strip (d) and the metals (a),(b) spread, thereby relieving stresses.

Abstract: PURPOSE:To improve the processing efficiency by comparing contents of already displayed data and those of display data after change with each other and displaying only a changed part again. CONSTITUTION:When display of display data is requested by a display request 1, display data is expanded in a post-change display data storage memory 4. Contents of this memory 4 and those of an already displayed data saving memory 5 are compared with each other by a comparing means 2, and the changed part of display contents is expanded in a display memory 6 and is displayed by a redisplay means 3. Thus, the processing time required for display is shortened because it is sufficient if only the changed part is displayed again and is confirmed at the time of partially changing the display screen.
