Title: Structure of drip pan for safety valve
Inventor: ORIMOTO KAZUHIDE
IPC: F16L51/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent jetted fluid from overflowing from a tray type pan when a safety valve is operated for jetting steam by fixing a pipe to the bottom face of the tray type pan with the pipe vertical end part protruded above a cylindrical seal ring height. SOLUTION: When a safety valve is not operated, an expansion difference between a safety valve side pipe 3 and an exhaust pipe 1 can be absorbed because mutual fixing is not accomplished between a tray type pan 2 and a seal ring 4 and between the seal ring 4 and the exhaust pipe 1. On the other hand, when the safety valve is operated and steam is blown out, a pressure from the upper end part of the seal ring 4 is larger than an atmospheric pressure P working on the outside of the exhaust pipe 1, so that a force pressing the seal ring 4 downward relatively works, and consequently, the jetted fluid is prevented from jetting out from between the lower end of the seal ring 4 and the bottom face of the tray type pan 2.

Title: Tape tension detection mechanism
Inventor: MORI KUNITAKA
IPC: G11B15/43
Filed: 1990-04-18
Abstract: PURPOSE:To reduce the influence given to the tape transport while detecting the effective tape tension and to ensure the stable tape transport by forming the air flow guide grooves on a tape contact surface in parallel to the tape running direction. CONSTITUTION:A tank 5 is provided at a part adjacent to an internal air port 3 of a drum 1. A pressure sensor 7 is connected to the lower side of the tank 5, and the air of the fixed pressure is supplied into an air inflow port 8 and then to the tank 5 via a small hole 6. The air is blown to a tape 10 wound round the drum 1 through the port 3. In this case, an air turbulence is divided by the air flow guide grooves 4 even if the air flow becomes a turbulent flow due to an increased tape speed. Thus the air flows in the fixed direction as a whole. As a result, the approximately equal force is applied to the entire width of the tape 10 and in the approximately same direction. Then the tape 10 can run stably with no twist nor vertical movement at all.

Filed: 1987-04-24
Abstract: PURPOSE:To pack an object to be packed having a large longitudinal width, by constituting a film end fixing apparatus so that a stretched film is fixed at several kinds of strengths on the end part side thereof and making it possible to pull out the film when the object to be packed is pushed up against the film and making it impossible to pull out the film when the film is folded in. CONSTITUTION:One of the motors is operated to grasp the end part of a film 7 between upper and lower stopper members 18, 18A by force possible to pull out the film and, next, a receiving table 5 is raised by a lift to push up the film 7 from below to stretch the same. In this case, the film 7 is pulled out from the gap between the upper and lower stopper members 18, 18A to hold proper pressure. Next, the other motor is also operated to grasp the end part of the film 7 between the upper and lower stopper members 18, 18A in a state impossible to pull out the film 7 and, in this state, the operation turning in the edge parts of the film 7 from three sides is performed. In this case, since the end part of the film 7 is fixed in the state impossible to pull out the film at the time of the operation, good packing can be performed in such a state that the film 7 generates no slackening.

Title: Controller for dot printer
Inventor: ISHII SHOZO
IPC: B41J2/515
Filed: 1989-04-21
Abstract: PURPOSE:To select image data by a small hardware at a high speed by providing a converter for converting an address for designating a printer and an address for designating a hammer into dot address of raster scan type image data received from a host system. CONSTITUTION:If hammer group is moved from right to left, when a right end print starting position is detected, an initial value 80 is loaded in a horizontal address counter 9. Thereafter, one is counted down at each detection of a printing position. When a counted value becomes '0', printing of 3 rasters is ended, and a hammer address counter 8 counts up one by one from '0' to M3 at each printing position. The outputs of the counters 8 and 9 are input to the addresses of an address conversion memory 10. The memory 10 is a read only nonvolatile memory, and converts the address of the position of the hammer group into dot address in the image data of each raster. Thus, a desired image data is selected with a small hardware at a high speed.
