Title: Traveling cutter
Inventor: KIHIRA TOSHIO
IPC: B23D25/04
Filed: 1984-05-14
Abstract: PURPOSE:To improve efficiency by forming a traveling-speed synchronization mechanism from a storke leading-out means which drives by leading-out a part of the first stroke of a cutting blade, thus reducing the dimension of the mechanism and permitting the cut of the high-speed traveling material. CONSTITUTION:When a material which travels penetrating through chucks 33,33' a dolly 16 is driven to increase its speed in synchronization with the traveling speed of the material, and then a traveling-speed synchronization signal is generated to drive the hydraulic cylinder 32 of a material cutting mechanism 18, and a cutting blade 30 lowers, and aprt of the first lowering stroke is introduced into a speed synchronization mechanism 20 by a stroke leading means 34, and the chucks 33, 33' catch the material. At the same time, a clutch 24 is cut-off, and the dolly 16 travels in synchronization with the material, pulled by the material, and the relative speed difference between the material cutting mechanism 18 and the material becomes zero, and the material is cut with the continuous lowering stroke of a blade 32. Thus, the dimension of the cutter can be reduced, since the speed synchronization mechanism does not necessitate a chuck driving means.

Title: Dot code
Inventor: NISHIO TAKETERU
IPC: G06K19/00
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To correctly read dots in a small printing area by arranging the dots at a pitch being about two times as long as their diameter between respective columns and also shifting dots to a column direction from the arrangement positions of dots in a 1st column by almost the diameter of a dot in a 2nd column to arrange them. SOLUTION: A printing part performing printing on a card defines the value of the best resolution pitch as, e.g. P0. Then, in a pixel (dot), its diameter becomes a value being equal to or slightly larger than the value P0. Even though the dot is not a perfect circle but regarded as a circle. Then, the diameter of the dot is defined as equal to the value P0 of the best resolution pitch. When the printing part prints a two-dimensional code on a card, it defines a length being about two times as long as the dot diameter as a printing pitch P in both horizontal and vertical scanning directions. However, when dots are observed in the direction of each column, a dot adjacent to the left or right side is shifted in the column direction for the value P0 of the best resolution pitch.

Title: Data communicating system and communication terminal used for the data communication system
Inventor: SHIICHI KAZUHIRO
IPC: H04W48/16
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To realize a communication service with high convenience by selecting a base station onto which registered terminals are not comparatively concentrated in the case of initial registration of the terminals and on the occurrence of hand-over. SOLUTION: In the data communication system consisting of base stations and mobile terminals, each base station transmits base station information including number of registered terminals. A base station information reception processing section 51 of a mobile terminal receives the base station information from each base station and a connection destination selection section 52 selects a base station to which a comparatively smaller number of terminals is registered as a connection destination on the basis of the number of registered terminals included in the base station information. A channel selection section 53 selects a communication channel for the selected base station.  Thus, it is avoided that the mobile station selects a base station whose data transfer efficiency is considerably reduced due to the concentration of the registered terminals onto the base station and then a communication service with high convenience can be realized.

Abstract: PURPOSE:To efficiently build up an AI system while decreasing the burden of software by utilizing the phenomenon that recorded information disappears within the prescribed time to make evaluation of the recorded information on a hardware side. CONSTITUTION:A recording film formed by adding 1-10% (atm.%) additive elements B, Ni, Ru and in systems of Na and K to an Sb-Se system which is one of chalcogenide systems of a phase changing material is provided as the recording film to store the association of the information to each other. The relaxation time of the phase changing type recording film consisting of only the Sb-Se system from the amorphous state to the crystalline state is about 10 years at 40-60 deg.C which is the service environment conditions, but if the elements such as Na of small ionization energy as well as B, Ni and Ru are added to this system, the information disappears of itself in about one day. The important information, i.e., the frequently used information is returned to the amorphous state by projecting the laser of high power to the film to rapidly heat and cool the film, by which said information is made to remain without being annihilated. The AI (artificial intelligence) system is thereby efficiently built up.
