Title: Rail condition monitor for traveling machine
Inventor: MOTOYAMA KAZUHIKO
IPC: G05D1/02
Filed: 1992-07-21
Abstract: PURPOSE:To carry out accurate judgment of the rail condition immediately while a machine is traveling by causing a computer to make judgment of the rail condition based on the gravimetry value at a detected position of the traveling vehicle, which position is detected by means of using a position detecting cable and an antenna. CONSTITUTION:A traveling machine detects the rail condition while the machine is traveling by means of a load cell 7 taking the strain of the reaction generated on a spring 8. In other words, the load fluctuation quantity found by the load cell 7 responding to the difference of level between the right and left rails and the vertical waviness of the rails in the traveling direction are successively measured as strains. The strains are converted into load through a transducer 9. The position of the traveling machine is detected by a cable 3 and an antenna 4. Signals from a computer 11 on the ground and judgment result indicating signals transmitted from a computer 10 provided on the traveling machine are received by an operation station 12 where judgment result containing position signals, or in other words, judgment result of each position are produced. Thus judgment of the rail condition is carried out successively.

Title: Print head for ink jet printer
Inventor: IINUMA TOSHIKATSU
IPC: B41J2/055
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To eliminate nonuniformity in the discharge characteristic of ink from each nozzle by a method wherein a sheet-like top plate provided with a supply port formed by arranging a plurality of holes of a prescribed size in the shape of a grid is so provided on a piezoelectric element as to cover a plurality of short and long grooves and an ink pool is provided on the supply port. SOLUTION: A top plate 2 is a sheet-like nickel plate formed by an electric casting method and has a supply port 201 formed by arranging square holes in the shape of a grid. When a voltage is impressed, piezoelectric element deformed parts 111 and 112 contract simultaneously and ink being present in a long groove 102 is discharged from a nozzle 401. When the impression voltage is canceled, the long groove 102 is restored to the original capacity and put under a negative pressure and, therefore, the ink is supplied into the long groove 102 from the supply port 201. Since the supply port 201 is formed by arranging the square holes of which one side is 10 μm long, the total area of the supply port 201 relating to the long grooves 102 in a plurality is invariant.  Accordingly, an operation of refilling the long grooves 102 with the ink becomes uniform and the discharge characteristic of the ink is made free of nonuniformity.

Title: Punching device
Inventor: SAITOU KATSUHIKO
IPC: B21D28/34
Filed: 1984-10-12
Abstract: PURPOSE:To obtain a punching device at a low cost by discontinuing the use of a collar which is used for preventing a punch from falling out. CONSTITUTION:When a plate material 10 is placed on a die 8, and an upper die substrate 1 is made to descend, a lower face 5b of a holding plate 5 fixes the plate material 10 onto the die 8, a pressure plate 6 pushes an upper end face of a punch 7 and the punch 7 descends. A pressure receiving surface 7c of the punch 7 depresses a bearing surface 3c of a punch supporting plate 3 against a spring 4 and punches the plate material 10. When the upper die substrate 1 ascends, the spring 4 pushes up the punch supporting plate 3, and simultaneously, and the punch 7 is also pushed up the bearing surface 3c of the punch supporting plate 3 and the punch 7 is drawn out of the plate material 10. A force of the time when the punch 7 is drawn out of the plate material 10 is mainly applied to the bearing surface 3c and the pressure receiving surface 7c, therefore, it does not occur that the punch 7 falls out downward. In this way, a collar formed in a conventional punch becomes unnecessary, the more the punch 7 is, the less expensive it becomes.

Title: Ink jet recording head
Inventor: HIROZAWA TOSHIAKI
IPC: B41J2/055
Filed: 1983-11-17
Abstract: PURPOSE:To prevent an ink-supplying tube from slipping off and air bubbles from penetrating in through a joint part, by a construction wherein a nozzle is formed as one body with an ink passage, a part thereof is bent, and the rear end of the nozzle is located in an ink contained in a liquid ink chamber. CONSTITUTION:An ink is supplied from an ink tank into a holder 13 in a recording head through the ink-supplying tube 8a, and the level of the ink 18 is maintained below the upper end of the nozzle 14. Air bubbles move up to the free surface of the ink 18 in the holder 13, and are removed. Since there is no place in the nozzle 14 where the air bubbles are caught or accumulated, the bubbles can be securely removed by suction.
