Inventor: NAGAMACHI SHUNJI
IPC: E01D22/00
Filed: 1989-06-30
Abstract: PURPOSE:To facilitate the repair and reduce the cost by providing a flange- shaped mounting part in the end part of a pipe-shaped unit with an outside diameter equal to the outside diameter of an existing pipe and interposing this mounting part in an existing inferior pipe removal part while fixing the mounting part to a bridge bed part. CONSTITUTION:A repair pipe 6, having an outside diameter equal to the outside diameter of an existing pipe 2, is provided, and a connection box unit 7, having holes for anchor bolts, if formed in one end of the repair pipe. Next, after an inferior pipe of predetermined section is cut and removed from a bridge bed part 1, the pipe 6 is placed in a condition butt-connected to the existing pipe 2, and the box unit 7 is fixed to the bridge bed 1 by the anchor bolts 13. Then the pipes 2 and 6 are connected by a pipe joint 4. While in the case of cables already housed in the pipe 2, it is constituted of a pair of right and left half-split pipes. In this way, without inserting a connection pipe part into the existing pipe as in the past, the internal contour volume can be ensured, while the necessity for high accurate and individual design is obviated, further the cost can be reduced.

Title: Combine harvester
Inventor: DOI YOSHINORI
IPC: A01D67/00
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a combine harvester preventing a controller for leveling an underframe from malfunctioning in automatically controlling its traveling direction. SOLUTION: When the output of correcting the traveling direction of a combine harvester is being conducted, the combine harvester of this invention stops the output of controlling inclination in the right and left directions for a preferred period of time determined by the degree of control in the right and left directions without outputting the control of inclination in the right and left directions by a controller for leveling the chassis according to the detected output value itself even when the controller detects the inclination of the chassis through an inclinometer (a sensor), etc. Thus it is possible to prevent the combine harvester from performing the control of inclination in the right and left directions based on the error signals due to the sway of the underframae by the control of inclination in the right and left traveling directions.

Abstract: PURPOSE:To prevent a flame failure due to excessive primary air by providing a gas expansion room connected with a gas passage on the side of downstream of a gas flow rate controller to make up for shortage of gas flow when the gas flow is abruptly throttled. CONSTITUTION:A gas expansion room 9 comprises a diaphragm 91 whose central section is reinforced by reinforcement plates 92, 93, a cover 94, a spring 95 etc., wherein the diaphragm 91 is fixed to a recess 96 formed on a device body 1 together with a cover 94. The figure shows the diaphragm 91 when the gas pressure is lower than a set value of the spring 95 and when the gas pressure rises, the diaphragm 91 is pushed to the right as shown by a chain line and at a maximum thermal power the spring takes a most contracted shape. When the gas rate is abruptly throttled and the gas pressure in the passage 13 becomes lower than the recoiling force of the spring 95, the diaphragm 91 is pushed to the left by the action of the spring. Forcing thereby the gas to the passage 13 through a branch 97, thereby shortage of gas rate due to abrupt throttling can be compensated.
