Patent JP-H09233618-A (JP)
Title: Panel made of resin
Inventor: UEDA SATOSHI
IPC: H02B1/30
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a boss by providing a slit in a boss portion for self-tapping purpose from an opening at the tip. SOLUTION: A slit 9 with a length of S1 is provided from a tip opening portion of a hole 5a formed in a boss portion 5. Width d of a slit 9 is adjusted by the size of a boss portion 5. Now, in order to make self-tapping screws common which are used for boss portions 5 and 6 for forming self-tapping portions A and B, if L1=L2=L is provided for the self-tapping screws 17 and 18, the actual tightening length for the self-tapping screw 17 is longer than that of the selftapping screw 18 (m2-m1). This longer portion is able to increase the tightening torque, and also the amount of compressed air in the hole 5a of the boss portion 5 increases. Therefore, for example, if the length S1 of the slit 9 is set to S1=m2-m1, the torque can be reduced and the amount of compressed air in the hole of the boss portion 5 can be made the same as that of the boss portion 6.

Title: Rubber for washing mold
IPC: B29C33/72
Filed: 1992-03-23
Abstract: PURPOSE:To exhibit excellent washing effect and suppress the generation of harmful gas from a rubber compsn. CONSTITUTION:A rubber compsn. for washing a mold is constituted by adding 20 pts.wt. of process oil, 1 pts.wt. of stearic acid, 10 pts.wt. of dicumyl peroxide, 50 pts.wt. of a silica gel, 10 pts.wt. of MDA and 5-60 pts.wt. of phenyldiethanolamine being aromatic amine.

IPC: G01N27/76
Filed: 1979-05-25
Abstract: PURPOSE: To facilitate the detection for the oxygen quantity based on the magnetization or the change of the weight and then realize the repetitive application, by using the substance which is obtained by giving the replacement to La in LaFeO 2  with 5W25atom% Na and solid solution for the sensor.  
     CONSTITUTION: The substance which is obtained by giving the replacement to La in LaFeO 2  with 5W25atom% Na and solid solution is used for the oxygen sensor. The magnetization of the solid solution is measured in the air, and then the pressure is reduced. Thus the magnetization lowers suddenly to be then fixed. This trend increases as the replacement amount increases within the range of the replacement amount of Na, i.e., up to 0.25 of the value of x in La 1-x Na x FeO 2 . In the result of this test, σ g (0) shows the magnetization in the air, and σ g (t) shows the magnetization after lapse of a certain time (t) under the reduced pressure each. Also the oxygen quantity can be known in the atmosphere from the weight change, and the repetitive application is possible since the weight change is reversible.
