Title: Preparation of 3-chloropropylamine salt
Inventor: YAMAGIWA SHIYUUICHI
IPC: B01J23/40
Filed: 1981-06-08
Abstract: PURPOSE: To prepare the titled compound useful as a synthetic intermediate of pharmeceuticals, etc., relatively easily, at a low cost, in high efficiency, by hydrogenating 3-chloropropionitrile in a solvent in the presence of sulfuric acid or hydrochloric acid and a platinum-group catalyst.  
     CONSTITUTION: The objective compound can be prepared by hydrogenating 3- chloropropionitrile in the presence of an acid selected from sulfuric acid and hydrochloric acid, a platinum-group catalyst (e.g. platinum oxide, supported palladium, etc.) and a solvent (e.g. anhydrous lower alcohol) under the hydrogen pressure of 0W50kg/cm 2 G at 0W25°C. 3-Chloropropionitrile is liable to be dehalogenated by the catalytic hydrogenation, and produces a large amount of propionitrile as a byproduct. However, the production of propylamine salt by the dehalogenation reaction can be suppressed in the presence of a specific acid selected from sulfuric acid and hydrochloric acid, a specific catalyst, and a specific solvent. The amount of the acid is ≥1mol, usually 1W2mol per 1mol of the raw material.

Title: Contact structure of mirror switch
Inventor: KAWASE TOSHIHIRO
IPC: B60R1/06
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To eliminate poor contacting condition in a mirror switch having a conter-contact without changing the shape of a die by introducing such a configuration that burr of a stationary contact touches a movable contact. SOLUTION: A stationary contact 15a is composed of a pair of stationary electrodes 17a and 18a and manufactured through insert molding. In insert molding, burrs 20a formed on the stationary electrodes 17a and 18a are oriented as directed to a rubber electrode 22a, so that no film of resin 24 is formed on the surfaces of the stationary electrodes 17a and 18a. Accordingly when a mirror angle adjusting button is pushed, the rubber electrode 22a touches the tip of the burr 20a certainly. Further there is no need to prepare a die for insert molding equipped with a projection for preventing formation of a film of resin 24, but a conventional die for insert molding may be used which eliminates necessity for alteration of the design.

Filed: 1988-04-13
Abstract: PURPOSE:To enable a low temperature heat treatment, prevent the deterioration of Schottky characteristics and an active layer, and obtain high performance, by forming a first semiconductor part and a second semiconductor part constituting an electric feeding part, by selective epitaxial growth. CONSTITUTION:An N-type active layer 2 is formed on a semiinsulating substrate crystal 1. After a tungsten silicide layer is formed, a gate electrode 5 is formed, by work process like dry etching. In this case, the heat-resisting temperature of a Schottky junction may be 600 deg.C. After SiO2 is stuck, this SiO2 is etched, thereby forming a side wall pattern 6 on the side wall of a gate electrode 5. An N<+> type GaAs layer 27 doped with Si is constituted as an epitaxial growth layer formed by MOCVD. In this manner, the layer 27 can be selectively formed on the gate electrode 5 and the part of an SiO2 pattern 6, without growing GaAs. The side wall pattern 6 of SiO2 is eliminated, and an N-type GaAs layer 17 doped with Si is again formed by MOCVD method.

IPC: C23C2/38
Filed: 1995-04-14
Abstract: PURPOSE: To eliminate the need for the conventional softening stage, such as bright annealing type, and flux treating stage by immersing a hard copper wire into a hot dip tin-copper alloy coating bath, thereby softening the hard copper wire. CONSTITUTION: The bare hard copper wire 2 is drawn out of a drum 1 and is introduced into a first vessel 3 in which the molten tin-copper alloy is put. The melting temp. of the tin is 23 deg.C. The melting temp. of the tin-copper alloy varies with the content of copper and 380 deg.C at 5% content of the copper and 500 deg.C at 15%. The temp. of the molten tin-copper alloy is preferably set at 300 to 600 deg.C. An oxidation reduction reaction occurs instantaneously because of the high temp. and oxygen-free state and an alloy layer is formed if the temp. is set at >=300 deg.C. The need for a flux treatment is eliminated. The bare hard copper wire 2 is softened and is immersed into a tin plating bath 8, by which the copper wire is plated with the tin.  The copper wire 2a subjected to the tin-copper alloy plating is subjected to the tin plating and, therefore, the copper wire 2b formed with the thick tin plating is obtd. The copper wire 2b is taken up on a drum 11. The change with lapse of time by a flux does not arise any more.
