Title: Printer
Inventor: SATO TSUTOMU
IPC: B41J29/50
Filed: 1985-06-27
Abstract: PURPOSE:To eliminate complicated manipulation and to prevent erroneous operation, by providing a movable guide plate which is adapted to abut against one side edge of a paper sheet to detect the position of the guide plate itself so that the condition of the right and left margins to be set may be automatically obtained. CONSTITUTION:In order to automatically supply a sheet of paper from an automatic paper feeder 2, a feed-out roller 25 is rotated in the direction indicated by the arrow, and therefore, the topmost one of paper sheets 5 held in a paper holder section 21 is fed into a printing section. At this time the paper sheet 5 is regulated widthwise by means of a body frame 3A and a movable guide plate 23. Then the paper 5 fed into the printing section is held between a platen 11 and pinch rollers 13A, 13B, and is transferred to a predetermined position where printing is started. Then a predetermined pattern of printing is made while the paper sheet 5 is fed line by line, and thereafter,the thus printed paper sheet 5 is shifted into a stocker 27, being guided by discharge rollers 28A, 28B to be stored in the stocker 27. With this arrangement it is possible to facilitate the manipulation of the printer and to prevent erroneous operation.

Title: Bolt, nut and connector
Inventor: SAKON TOSHIO
IPC: F16B35/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To reduce stress relax amount after fastening so as to prevent loosening by generating unidirectional setting texture in the axial direction of the main stem part, and generating equi-axed polycrystalline texture in a screw part integrated with the main stem part. SOLUTION: A bolt 11 is formed by the main stem part 12 which has unidirectional setting texture and the setting direction of which agrees with the axial direction of the bolt 11, and a screw part 13 integrally formed on both ends of the main stem part 12, which have equi-axed polycrystalline texture. In manufacturing such bolt 11, first, raw material formed by the part scheduled to form the main stem part 12 and the part scheduled to form the screw part 13 is manufactured by unidirectional casting, then only the part scheduled to form the screw part 13 is subjected to plastic deformation by forging, and the whole is heat-treated. Thus, only the part scheduled to form the screw part 13 is recrystallized to become equi-axed polycrystalline texture. After that, it is machined into a bolt shape.  Accordingly, the creep strength of the bolt material can be heightened and the Young's modulus can be made smaller so that the stress relaxation is hard to occur.

Title: Valve seat of internal combustion engine
Inventor: SUZUKI KEITARO
IPC: F01L3/02
Filed: 1993-05-21
Abstract: PURPOSE:To improve initial matching property between a valve seat and a valve so as to reduce initial abrasion amount of a seat surface, so as to improve durability of the valve seat by forming a chrome film on the seat surface while manufacturing the valve seat with alloy, in the valve seats facing the intake/ exhaust valves of an internal combustion engine. CONSTITUTION:In an internal combustion engine, an intake/exhaust passage 2 communicated with a combustion chamber 1 is opened and closed by a valve 3. A valve seat 4 is arranged in the position of a part which is closed by the valve 3 in the intake/exhaust passage 2. A seat surface 4a is arranged in the position where the valve seat 4 and the valve 3 are slide and fit with each other. In this case, a chrome film is formed on the seat surface 4a while manufacturing the valve seat 4 with alloy. The chrome film of the seat surface 4a is beaten by the valve 3 and deformed plastically so as to generate surface contact condition. The chrome film is exposed to a high temperature, the surface thereof becomes chromium oxide so as to generate self lubricating action. It is thus possible to improve durability of the valve seat since initial matching property between the valve seat 4 and the valve 3 is improved and the initial abrasion amount of the seat surface 4a is reduced.

Title: Operating system of unmanned traveling car
Inventor: ABE EIJI
IPC: G05D1/02
Filed: 1980-10-08
Abstract: PURPOSE:To facilitate the traveling of an unmanned car at the area where the traveling is difficult for the car by only a marker system and at the same time to transmit a command to the car from a point on the ground, by adding an induction line to the operating system using a marker system and also applying the traveling by electromagnetic induction. CONSTITUTION:A car 1 travels by a marker system until it reaches a branching area, and only a mark sensor 4 works to detect the entering angle to the 1st mark M1 and the shift from the center of the mark. Thus a correction is given to the  locus. When the car 1 reaches a zone Z of the induction line G stretched at the  branching area, the sensor 4 is switched to induction line sensors 5l and 5r by reduction of the induced voltage due to a cross point 6. Thus the traveling is carried  out for the car along the induction line. Furthermore, a traveling command (turn- right command) is given from a ground controller 10 by the FSK system to actuate  only the sensor 5r of the right side. Thus the car turns right, and the sensor 4  works again when the car reaches a cross point 7. And the car travels toward the 3rd mark M3.
