Title: Thermal printer
Inventor: HATTORI SHIGENORI
IPC: B41J33/38
Filed: 1986-11-11
Abstract: PURPOSE:To perform clear printing and prolong the useful lives of component parts, by taking up a printing ribbon by an amount equal to the amount by which the ribbon is paid out concurrently with a movement of a carriage, while constantly applying an appropriate tension to the ribbon even when the ribbon thus paid out is extended or contracted. CONSTITUTION:Concurrently with a movement of a carriage 3, a rotary shaft 15 is moved rightward in a body with the carriage 3. A pinion 19 is engaged with a toothed belt 17, is rotated clockwise, and a friction roller 20 fitted to the rotary shaft 18 is also rotated in the same direction. A take-up spool 24 pressed against the friction roller 20 is rotated counterclockwise to take up a used part of a printing ribbon 29. Since the diameter of the friction roller 20 is set to be slightly greater than that of the pitch circle of the pinion 19, the rotational moving quantity at a peripheral surface of the friction roller 20 is slightly greater than the moving quantity of the carriage 3, resulting in a tension on the ribbon 29. The difference between the take-up quantity and the moving quantity is substantially constant, irrespective of the roll diameter of the ribbon 29 taken up on the take-up spool 24, so that a stable operation can be achieved for a long time.

Title: On-vehicle obstacle detecting device
Inventor: YAMAZAKI SHIGERU
IPC: G01S17/93
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide an on-vehicle obstacle detecting device capable of avoiding inclusion of light or radio waves or the like outputted from other vehicles for accurately detecting an obstacle. SOLUTION: A time slot is generated by a time slot generating part 11 using a reference time from a reference time generating part 18. An optional slot inside the time slot is set by a slot setting part 12 as a slot of one's vehicle. A slot determining part 13 determines whether or not a slot number of another vehicle received by a radio transmission/receiver part 17 competes with a slot number of one's vehicle. When it is determined that the slot number of one's vehicle does not compete with the slot number of another vehicle, the slot of one's vehicle is decided as an occupation slot by an occupation slot deciding part 14. When the slot number inside the time slot matches with the occupation slot of one's vehicle, an obstacle detecting operation is performed just for an occupation slot time by an obstacle detecting part 16 controlled by a controller 15.

Abstract: PURPOSE:To obtain the polarizing sheet having excellent moisture permeability, wear resistance and surface strength by providing polyvinyl alcohol (PVA) polymer layers via adhesive agent layers between the polarizing blank film and crosslinkable resin cured matter layers. CONSTITUTION:The adhesive agent layers 2, 2 are provided on both surfaces of the polarizing blank film 1 and the PVA polymer layers 3, 3 and the crosslinkable resin cured matter layers 4, 4 are laminated thereon. Since this PVA polymer layer 3 consists of a resin contg. a hydroxyl group, the layer reacts also with the crosslinking agent at the time of forming of the crosslinkable resin cured matter 4 and the secure adhesion is attained even if an anchor layer is not provided between these layers. While the brittleness of the crosslinkable resin cured matter layer 4 is covered by the PVA polymer layer 3, the moisture permeability of the PVA polymer layer 3 is covered by the crosslinkable resin cured matter layer 4. The advantages of both of these layers are thus effectively utilized.
