Abstract: PURPOSE: To provide a bidirectional running device for use with an intra-pipe running pig capable of bidirectionally running certainly and safely within a pipe having a mitre bend. CONSTITUTION: The peripheries of pig blades 2, 2' contact with the inner wall of a pipe P in such a condition as warped slightly greater than the inside diameter of the pipe. Seal discs 3 formed from compressive material are installed pinchedly between a pair of pig plates 2, 2 and another pair of pig plates 2', 2'. The pig plates 2, 2' are coupled with the seal discs 3 by respective coupling rods 4 in such a way as movable slightly in the axial direction, and the spacing is made variable by two flanges 1m. The pig plates 2, 2' are deformable so that they can be reversed in the pipe axial direction, and thus the reverse can be conducted smoothly.

Abstract: PURPOSE:To inform the user of the lack of the printing sheets when a printing request is issued in case of lack of printing sheets. CONSTITUTION:When the user inputs the number of supplied printing sheets to a printer 11, number-of-supply printing sheets input means 1 informs printing sheet used amount file managing means 2 of the number of the supplied print sheets.

When the user outputs a printing request, printing required number confirming means 3 obtains the number of required printing sheets and informs the printability judging means 4 of the number. The means 4 compares the number of the remaining sheets obtained from the file 6 through the means 2 with the number of the required sheets, and informs the user of the lack of the printing sheets through error informing means 5 if the number of the remaining sheets is less than the number of the required sheets.

Title: Inclined oil content bearing and manufacture thereof
Inventor: KIKUCHI ISAMU
IPC: F16C33/10
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To properly prevent oozing out of oil in a bearing due to pump action in case of high speed rotation so as to prevent oil leakage by controlling the distribution of oil content between each part of the bearing. SOLUTION: Average oil hole diameter between each part of a bearing is made smaller than that on an outside diameter side to obtain a bearing body having low oil content on an inside diameter side and high oil content on an outside diameter side, and remaining oil is moved and supplied onto the inside diameter side by capillary phenomenon when impregnated oil is consumed due to the use for many hours to continue proper oil supply. Moreover, proper supply conditions can be formed in the same way by making average oil content on the inside diameter side of the bearing smaller than average oil content on the outside diameter side.  Furthermore, favorable oil supply conditions can be formed and maintained by making a compression rate in the direction of thickness on the inside diameter side larger than that on the outside diameter side and applying oil containing treatment in a sizing process after pressure powders are formed. Changes of oil content can be adequately adopted even in the peripheral direction or the direction of length of the bearing.
