Title: Die structure for blow molding machine
Inventor: NAWATA MASAYOSHI
IPC: B29L22/00
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To prevent a vertical movement fault due to an interference of a rod with a guide when vertically moved or damage or breakage of a die by forming a guiding mechanism for vertically moving and guiding a die housing in a floating structure. SOLUTION: A housing 18 fixed to a screw rod 20 and a guide rod 22 is lowered in association with the rod 20, lowered without interference with the guidance of the rod 22, and an outer periphery of a die mandrel is projected outward from the housing 18. Since a guide member for guiding the rod 22 is floated and supported in a horizontal direction and is movable, a difference of a distance in association with a thermal expansion is buffered, the rod 22 is easily slid without increasing its sliding resistance from the guide member so that the mandrel and the housing 18 are smoothly separated. Thus, even if the rod 22 is tightly engaged with the guide member, the sliding resistance is not increased, but can be smoothly slid to facilitate selecting of engagement.

IPC: G01M17/007
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To enable detecting the generation of layer short or leakage, independently of the state of a battery. SOLUTION: A current flowing in a battery 3 of a vehicle and a voltage of the battery 3 are measured with a battery current measuring means 23b and a battery voltage measuring means 23d, respectively. In the state of operation of a plurality of loads connected with the battery 3, data of resistance values at the normal time between a plurality of wire harnesses 6A-6N connecting the battery and the loads and the battery 3 are stored and held in a load current data holding means 25bA. A resistance value calculating means 25A calculates the resistance value R between the battery 3 and the wire harnesses 6A-6N.  When a resistance value comparing means 25B judges that the resistance value R does not coincide with the data at the normal time between the battery 3 and the wire harnesses 6A-6N in the case of operation of the loads 17A-17N which data are held in the load resistance data holding means 25bA, it can be judged that abnormal currents flow in a plurality of the wire harnesses 6A-6N.

Title: Method of reading marking
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/00
Filed: 1987-03-17
Abstract: PURPOSE:To prevent erroneous detection of even a marking having fine defects in a picture forming apparatus by arranging a plurality of photocell detecting elements of a marking sensor for a recording paper in the direction crossing the recording paper transfer direction. CONSTITUTION:A marking sensor 17 has a plurlaity of light receiving element converters a-m arranged in the direction crossing recording paper transfer direction. On the other hand, a marking 18a recorded on a record by a recording head extends the edge E in the direction crossing the recording paper advancing direction, while it has microscopically enlarged dots x and dot lacking portions based on abnormal discharge. And when the recording paper moves in the direction of arrow, the photocell light receiving elements b, l corresponding to said portions y, y' detected by the marking sensor 17a do not generate signals. However, when at least four elements among m pieces of said elements for example detect, a detecting circuit judges it as the passage of marking edge E. Thus, even if the marking includes fine defects, high accuracy detection can be chieved without any errors.
