Title: Top seal packing remover for spear valve
Inventor: SUZUKI TOSHIO
IPC: B67D1/04
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To automatically remove a top seal packing fitted into a groove formed on a flange of a valve body without manpower. SOLUTION: The top seal packing remover 15 comprises a pull-out part 19 for pulling out a top seal packing 51 from a valve body 50 and a cutter 21 for cutting the packing 51 pulled out by the pull-out part 19. The top seal packing 51 is pulled out of the valve body 50 by the pull-out part 19, and the cutter 21 cuts the pulled-out packing 51. Thus even when the packing 51 is fitted into a groove 50c formed on the valve body 50, it can be automatically removed from the valve body 50 without manpower.

Title: Compact jet propulsion boat
Inventor: MATSUMOTO CHIHIRO
IPC: B63B35/73
Filed: 1992-10-24
Abstract: PURPOSE:To improve the operational property by connecting one side throttle lever provided to one side handle lever to an engine to drive and rotate a pump unit provided to the other side, while combining the other side throttle lever provided to the other side handle lever and a pump unit provided to the one side, to the engine. CONSTITUTION:When a boat is started by turning to the right, a throttle lever 1f1 provided to the starboard side is rotated to a handle grip 1d2 side, and the throttle valve of an engine 21 at the port side is opened, so as to increase the output of the engine 21 at the port side As a result, the rotation of an impeller 3c1 at the port side is increased, and a jet is exhausted strongly to the rear side from a steering nozzle 3d1 at the port side. On the other hand, since almost no jet is exhausted from the steering nozzle 3d1 at the starboard side, the boat body is turned to the right by the difference of both jets. Consequently, since the water in a water suction duct 3b1 at the port side is not bent at the part of the steering nozzle 3d1 but exhausted to the rear side, an exhaust port loss as in the conventional boat is reduced.

Title: Current detector
Inventor: ABE HIROSHI
IPC: G01R15/20
Filed: 1989-11-30
Abstract: PURPOSE:To obtain a detector having both of the high sensitivity characteristic within a small current range requiring resolving power and a wide current detection range for a large current range by constituting a core by inserting other ferromagnetic material different in saturated magnetic flux density in the central part of a ferromagnetic core in series. CONSTITUTION:A through-type electric wire 5 allowing a current to be measured to flow is allowed to pierce through a ferromagnetic core 3. The magnetic flux generated by the current of the electric wire 5 is converged by the core 3 to generate magnetic flux in the space of the magnetic gap 1 of the core 3 and the intensity of the magnetic flux is measured by a magnetism-sensitive element 2. A thin plate-shaped ferromagnetic material B4 low in saturated magnetic flux density is inserted in the central part of the core 3 formed of a ferromagnetic material A high in saturated magnetic flux density and a core is constituted by the series connection of two or more kinds of magnetic materials. A current detector using the core thus constituted has two-step sensitivities across a point where the part of the ferromagnetic material B4 is saturated. That is, a detection current range can be extended by keeping conventional sensitivity within a small current range requiring resolving power and lowering sensitivity within a large current range.

Title: Ink jet recorder
Inventor: NAKAMURA TAKUMA
IPC: B41J13/02
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To enhance image quality by making variable the nip position of a sheet at the section for discharging a printed sheet thereby preventing the sheet from touching an ink jet head due to cockling or bending. SOLUTION: In general, cockling is increased as the quantity of ink increases and the thickness of a sheet is decreased and a flexible sheet, e.g. a board, is susceptible to bending. A control section acquires sheet type designating information, identifies the image type, converts the information into a nip position using a nip position table, converts the difference from current nip position into the driving amount of a stepping motor 17 and rotary drives the stepping motor 17. Consequently, a movable lever 16 is displaced vertically to cause displacement of a roller 11 and a spur 12 such that a sheet is nipped at a specified nip position A. According to the arrangement, the sheet is prevented from touching a recording head due to cockling or bending and deterioration of image can be suppressed.
