Title: Preparation of 1'-methyl-2'-(3-pyridyl)-2'-pyrroline
Inventor: KISAKI TAKUROU
IPC: A24B15/38
Filed: 1978-10-25
Abstract: PURPOSE: To prepare the title compound useful as an intermediate of a nictotine derivative, in high efficiency, by extracting an alkaline aqueous solution of pseudoxyniotine with a non-aqueous organic solvent, removing the solvent from the extract, and refluxing the residue with benzene.  
     CONSTITUTION: 1'-( 3-Pyridyl )-4'-methylaminobutan-1'-one ( Pseudoxynicotine ) hydrochloride is dissolved in water, and adjusted its pH to pref. ≥12 by adding an alkali. The solution is extracted with a non-aqueous organic solvent such as chloroform, and dehydrated by adding a dehydrating agent to the solvent phase, and the organic solvent is removed under reduced pressure. The residue is dissolved in benzene, and refluxed under atmospheric pressure to remove the water completely from the residue. Benzene is distilled off under atmospheric pressure to obtain the objective N-methylmyosmine.  
     EFFECT: Free from resin formation by distillation.  
     USE: Medicine, pesticide, an agent for improving taste and flavor of tobacco., etc.

Title: Medical rubber stopper
Inventor: SUDOU MORIHIRO
IPC: A61J1/05
Filed: 1995-05-29
Abstract: PURPOSE: To prevent a rubber stopper from falling into a container even if an urgent mixing operation is performed by forming the lower side of the top surface corresponding to the needle sticking part of the upper side of the top surface as a flat part with a diameter at least larger than that of the pincushion part, and providing a leg part outside of the flat part. CONSTITUTION: A flat part having an area larger than that of a needle sticking part of the top surface is formed on the chemical contact side of the lower surface of a rubber stopper. A leg part is provided outside of the flat part. The other part is formed similarly to an ordinary rubber stopper, and there is no special limitation. A material for the rubber stopper is not specially limited, and for example, isobutylene-isoprene copolymer rubber, and chlorinated rubber thereof are used. Thereby, even if a needle point is pressed right to the outside of the needle sticking part of the top surface and stuck straight, and even if the needle point is pressed to the position a little to the outer periphery from the center of the sticking part and stuck slantingly toward the outer periphery, this arrangement prevents the rubber stopper from falling into the container.

Title: Searching method for grounding point
Inventor: SHIMADA RYUICHI
IPC: G01R31/02
Filed: 1985-06-14
Abstract: PURPOSE:To search for a grounding point on an electric power line easily and accurately by allowing a detector to detect magnetic flux produced from the electric power line with a grounding current which flows from an AC power source to the grounding point and transducing it into a sound. CONSTITUTION:If a grounding point 6 is grounded, the grounding current 8 flows through the electric power line 4 from the AC power source 2 to the grounding point 6 to produce intense magnetic flux 10 at its periphery. This magnetic flux 10 is detected by the detector 12 and transduced into the sound by a portable amplifier 14 with headphones which is connected to the detector. An inspector wear an amplifier 14 moves the detector 12 along the electric line 4 while hearing the AC sound from the headphones. At this time, when the detector 12 is put close to the electric power line 4 where the current 8 flows, the AC sound of the power source 2 is heard strongly. When the detector 6 moves beyond the grounding point 6, on the other hand, no current flows there, so almost no AC sound is heard. Thus, the grounding point on the electric power line 4 is searched for easily, speedily, and accurately.

Title: Infrared sensor and manufacture thereof
Inventor: MORI TAKETOSHI
IPC: H01L37/00
Filed: 1992-05-22
Abstract: PURPOSE:To make a contact hole in an electrode pad without destroying a cross-linked part. CONSTITUTION:A chromium(Cr) film 16 and a copper(Cu) film 17 are deposited sequentially on an electrode wiring layer 15 to form electrode pads 30a, 30b and then a silicon oxynitride film 18 is formed thereon. A contact hole 19 is then made through the silicon oxynitride film 18. A silicon substrate 11 is then anisotropically etched with aqueous solution of hydrazine from the rear surface through an opening 20 in the silicon oxynitride film 13 thus forming a crosslinked part. Since an etching resistant copper film 17 is formed on the top layer of the electrode pads 30a, 30b, the electrode pads 30a, 30b are not dissolved into the etching liquid at the time of anisotropic etching. Furthermore, a previously formed contact hole 19 protects the crosslinked part against breakage.
