Title: Removal of isobutene
Inventor: YOSHIMURA MASAHITO
IPC: C08F4/00
Filed: 1979-12-24
Abstract: PURPOSE: To remove isobutene from an isobutene-containing mixture composed mainly of 4C hydrocarbons, by contacting the mixture with anhydrous AlCl 3  catalyst dissolved in nitroparaffin at above room temperature pref. in the presence of diethoxyethane, etc., thereby polymerizing the isobutene.  
     CONSTITUTION: An isobutene-containing mixture composed mainly of 4C hydrocarbons is brought into contact with anhydrous AlCl 3  catalyst dissolved in a nitroparaffin (e.g. nitromethane) at 25W60°C, and the polymerized isobutene is removed from the system. The reaction of n-butene is remarkably suppressed further by carrying out the contact of the mixture with said catalyst in the presence of a compound of formula R 1 -O-R 3 -O-R- 2  (R 1  and R 2  are phenyl, alkyl or alkenyl; R 3  is CH 2 , C 2 H 4 , C 3 H 6 , or C 2 H 4 OC 2 H 4 ), and the isobutene is polymerized more selectively to obtain the polymer having narrower molecular weight distribution.  
     EFFECT: The removal of isobutene can be carried out essentially without loss of n- butene.

Abstract: PURPOSE:To make mass production by forming a conductive polymer layer by an electrolytic polymn. reaction on the surface of a conductive base body, then covering the conductive polymer layer by an electrolysis with a catalyst layer which develops a catalyst function to the reduction reaction of a prescribed gas. CONSTITUTION:For example, a BPG electrode is formed by cutting out a circular column from the plate of basal plate pyrolytic graphite and adhering a lead wire 4 to the base 1a thereof, then inserting the base body into a 'Teflon(R)' tube 5 and insulating the tube with an insulating adhesive agent 7. The electrolysis is then effected by using a 3-electrode type cell with the above- mentioned electrode as a working electrode and a platinum electrode as a counter electrode and using an acetonitrile soln. as an electrolyte to form the conductive polymer layer 2. The auxiliary catalyst layer 8 is thereafter formed by effecting the electrolysis using an aq. soln. contg. silver nitrate as the electrolyte. A rhenium layer is further formed as the catalyst layer 3 by effecting the electrolysis using an aq. soln. contg. rhenium nitrate as an electrolyte. The sensor for gaseous CO2 is thereby produced.

Abstract: PURPOSE:To ensure confortable riding of a car by providing a means so that a seat belt is relaxed for a fixed time after tension is applied to it for a certain time and the restraint condition can be released by a separate manual operation. CONSTITUTION:When tension is applied to a belt by a human body for a fixed time, it is detected by a detector 11, and a base voltage is fed to a transistor 13 through a delay circuit 12, turning that on.

Title: Wire used in multiwire saw
Inventor: KAMITAKA MASUO
IPC: B24B27/06
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To improve the slurry holding force so as to shorten the slice time by forming a wire for cutting an object material while slurry is supplied in the shape of being spirally twisted. SOLUTION: A wire 8a uses a brass-plated (Zn,Cu) piano wire represented by JIS-G-SWRS82A. This one wire is worked to be spirally twisted. Working is thus performed to form a spirally recessed part on the surface. In the case of using the wire 8a to cut a silicon block with a multiwire saw, slurry is held in the recessed part of the wire surface. Accordingly, as compared with the conventional wire, the slurry holding force can be improved so as to increase the slurry supply amount per cutting unit hour. Thus, the table lowering speed can be increased so as to shorten the cutting time, so that the production efficiency can be improved and the production cost can be decreased.
