Abstract: PURPOSE:To secure such a liner that is self-lubricative, long in service life and ease of maintenance by installing multiple dents on the surface of a copper- alloyed platelike substrate, and filling up each porous solid lubricant in these dents. CONSTITUTION:In a platelike substrate 1 made of a copper alloy such as brass and aluminum bronze or the like, there are provided with multiple dents in which a porous solid lubricant 2 is filled up. Depth of each dent is 10-80% of thickness of the substrate 1, and its diameter is 5-30-mm in size, and as for the porous solid lubricant 2, it is produced after containing olefine oligomer or polyalpha-olefinic lubricating oil 60-85wt.% and solid lubricant 0-10wt.% in polyethylene of more than one million in means molecular weight. Moreover, a linear oil groove 3 is installed in a surface of the substrate 1, through which lubricating oil or grease is fed out of the outside at need. With this constitution, a liner comes to self-lubricity so that lubrication from the outside can be made unnecessary or minimal.

Title: Vehicular shock eliminator
Inventor: MATSUI TOSHIJI
IPC: B60R19/56
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To maintain high strength against a large load involving a shock by providing a bumper formed to have each of three or more shock contact surfaces positioned approximately on the same line. SOLUTION: When a vehicle equipped with a bumper collides with a collision object such as another vehicle, a shock load F due to the collision acts on shock contact surfaces 64 on top 61 of the bumper. In this case, as the shock contact surfaces 64 are formed at a plurality of positions along the same line 68, the shock load F evenly acts on each shock contact surface 64. As a result, a load comes, to evenly act on each of a plurality of joint bodies 60. Thus, the deflection curve of the bumper via a critical load becomes smooth, and buckling does not take place, thereby ensuring the freedom of a bumper cross sectional form from expansion.

IPC: H02H3/38
Filed: 1978-03-03
Abstract: PURPOSE: To eliminate malfunction in the event of no input to one side and ON/ OFF switching of input to the other side of two alternating current input signals, by feeding back the respective outputs of a pair of rectangular wave circuits to the other input sides.  
     CONSTITUTION: Since resistances 20, 21 inserted into feedback circuits 18, 19 are selected at values not influential to usual operating characteristic, normal operation is performed as far as two alternating current input signals are normal. Suppose signal of waveform V 1  is applied to input terminal 1 while no input being given to terminal 2, output waveform V 5  of rectangular wave circuit 5 is caused by the function of feedback circuit 18 to be completely in reverse phase to output waveform V 4  of a rectangular wave circuit 4, so that output V 9  of time limit circuit 9 becomes a continuous "1" signal. On the other hand, input V 10  of time limit circuit 13 becomes a continuous "0" signal, so that a stable state without input such as waveform V 3  may be obtained, thereby preventing malfunction.
