IPC: G06K9/03
Filed: 1987-08-04
Abstract: PURPOSE:To enable an operator to devote himself/herself to hand-written input by displaying the recognized result of the hand-written input at an optional timing. CONSTITUTION:When data are inputted to a tablet 1, a character segmenting part 3 reads out the input coordinates and simultaneously checks whether data are inputted to a display specifying area 10 or not. At the time of inputting data to the area 10, the segmenting part 3 commands a display control part 7 to display a hand-written input recognizing result stored in a recognition buffer 8b on a display device 9a in stead of the display of an input holograph stored in a holograph buffer 8a in a display buffer 8.

Title: Vapor deposition device by reaction
Inventor: NOCHI KIDAI
IPC: C23C14/24
Filed: 1981-12-02
Abstract: PURPOSE:To control the compsn. distributions in the thickness direction of films formed  by reaction easily in a device for allowing the vapor flow from an evaporating source to react with the gas introduced from the outside by combining a nozzle for viscous flow of the gas and a nozzle for molecular flow of the gas. CONSTITUTION:For example, gaseous O2 is injected toward a polyimide substrate 7  wound in a direction 21 from a nozzle 14 which emits viscous flow in a device for  vacuum vapor deposition, to allow the same to react with the vapor flow of iron 15  which is an object to be melted in an evaporating source 4 going toward the substrate 7. A thin magnetic film of iron oxide is thus formed on the substrate 7. Here, if a  nozzle 18 which emits molecular flow is disposed and gaseous O2 is injected therefrom, the direction of the gas is unified in one direction; therefore, the gas reacts with the  iron of the evaporating molecules that come flying only in a certain specific place.  Thus, the above-described purpose is achieved. In the nozzle 18, the gas is injected  and adiabatically expanded by a nozzle 8 in a chamber 13 which is evacuated to a  high vacuum with a pump 13. The impulse waves generated by said expansion are  removed with a skimmer 9, and the componenets having the velocity vector except in  the specific direction are evacuated with a pump 12, whereby the molecular flow  unified in one direction is obtained.

Abstract: PURPOSE:To reduce the amount of ion implanted and to perform heat treatment at low temperature for manufacturing a high-quality surface single-crystal SOI- type semiconductor substrate at low cost by a method wherein an impurity which, combining with constituent atoms of a semiconductor substrate, forms an insulator is preliminarily added to the semiconductor substrate and then an impurity having a gettering function is implanted in the semiconductor substrate by ion implantation and the semiconductor substrate is finally heat- treated. CONSTITUTION:An impurity which forms an insulating film by combining with silicon atoms is added to a silicon substrate 11. For example, about 2X10<13>cm<-3> of oxygen atoms is added to the silicon substrate 11. Nextly, an impurity which, being electrically inactive, assists the oxygen atoms in moving is implanted in the silicon substrate 11 by ion implantation. For example, about 2X10<16>cm<-2> of carbon atoms 13 are implanted in the silicon substrate 11 by ion implantation. Lastly, the silicon substrate 11 is heat-treated at 1000 deg.C or thereabout for moving the carbon atoms 12 and combining the oxygen atoms 12 with the silicon atoms. Consequently, a buried oxide film 14 and a silicon single-crystal thin film 15 are formed. An SOI-type semiconductor substrate is thus completed.

CONSTITUTION:This graphite crucible has a vertically divided structure and an almost cylindrical upper unit 1 of the crucible is placed on the bottom unit 2 of the crucible. A vertical slit 3 made on the above-mentioned upper unit 1 of the crucible can prevent the upper unit 1 of the crucible from breaking by stress concentration due to formation of SiC. After a cylindrical member 4 composed of a carbon fiber-reinforced carbon material is engaged with the outer periphery of the upper end part of the bottom unit 2 of the above-mentioned crucible, the upper unit 1 of the crucible is inserted into the cylindrical member 4. The upper end part of the cylindrical member 4 is allowed to come to a somewhat higher level than the melt level so as to prevent deformation or expansion of the upper unit 1 of the crucible when melting the raw material of a single crystal or growing a single crystal. The thickness of the cylindrical member 4 is 1/4 to 1/3 the thickness of the upper unit 1. In addition, a crucible receiving unit is formed monolithically with the bottom unit 2 of the crucible and the bottom unit 2 is placed directly on the upper end part of the crucible shaft 5.

IPC: G11B20/12
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent an unauthorized copy by the forging of copy-permissible/ impermissible information. SOLUTION: A copy permissible/impermissible judging part 108 judges whether a copy is permitted or not in the device 200 of a receiving side based on the first copy-permissible/impermissible information generated inside the device 100 of the sending side. A switch 107 is turned on or off in accordance with the judged result of the copy-permissible/impermissible judging part 108 and forms the transmission path of the information of the main body to the device 200 of the receiving side when the copy is permitted and interrupts the transmission path of the information of the main body to the device 200 of the receiving side when the copy is not permitted. Consequently, the unauthorized copy to be generated because the first copy-permissible/impermissible information are forged in between the device 100 of the sending side and the device 200 of the receiving side is effectively prevented.

Title: Pneumatic tire
Inventor: UEDA MINORU
IPC: B60C9/00
Filed: 1982-11-08
Abstract: PURPOSE:To enhance the durability of the side wall part of a tire, with comfortable ride and steering stability of a motorcycle maintained, by forming a groove-shaped part recessed toward the inside of a tire along the entire periphery of the side wall part of the tire and by imbedding, at the groove bottom, a cord-shaped reinforcing element that prevents elongation of the tire. CONSTITUTION:In an air-inflated tire 1 for a motorcycle, a groove-shaped part 5 recessed toward the inside of the tire 1 is formed at the middle part between a crown part 2 and a bead part 3. At the bottom part 6 of this groove-shaped part 5, a cord-shaped reinforcing element 7 is imbedded along the periphery of the tire 1. The reinforcing element 7 is made of steel cord or the like. With this contrivance, the section of the side wall 4 takes the form of a wave as a whole, thereby dispersing bending points during running in order to enhance the durability of the tire. In addition, owing to the reinforcing element 7, the elongation of the groove-shaped part 5 is restricted to keep the wave-shape sectional form of the tire as it is. As a result, the comfortable ride and improved steering stability can be obtained.
