Title: Preparation of 2,3-dichloropropionitrile
Inventor: MIYAHARA SHIYOUICHIROU
IPC: C07C67/00
Filed: 1981-02-18
Abstract: PURPOSE: To obtain the titled compound which is a useful industrial intermediate safely, by chlorinating acrylonitrile by blowing chlorine while dropping the acrylonitrile to an inert solvent in which chlorine is dissolved to a state near the saturation.  
     CONSTITUTION: Acrylonitrile is chlorinated with chlorine while blowing the chlorine and dropping the acrylonitrile to an inert solvent, e.g. carbon tetrachloride or trichloroethane, in which the chlorine is dissolved to a state near the saturation simultaneously to give 2,3-dichloropropionitrile. Usually, a catalyst and the acrylonitrile are charged into a reactor, and the chlorine gas is blown thereinto to initiate the reaction and cause intermittent exothermic phenomenon with a periodic induction period. However, the continual blowing of the chlorine gas into the continual saturation state of the reaction system provides the reduction of the amount of oxygen in the system or below which is considered as a cause of a rapid reaction to a given amount or below. The control of the reaction is easily carried out, and the stable mild reaction conditions can be kept with a small amount of by-products.

Filed: 1986-02-05
Abstract: PURPOSE:To eliminate the modal distribution noise by coupling two sets of semiconductor lasers optically and providing a saturable absorbing body onto an optical path between them so as to avoid the selection of the semiconductor lasers by their emitting wavelengths. CONSTITUTION:The titled device consists of the semiconductor laser 2, the saturable absorbing body 3 and the semiconductor laser 4. In applying direct modulation to the semiconductor laser 2 by a drive current 6 being the superimposition of a digital electric signal on a DC current, its optical output 5b is changed, e.g., as shown in figure and the power of an optical output is constant at each pulse. It is known that the spectrum of the laser optical output 5b at each pulse is changed at each time at random. Since the random optical power between spectrums eliminates the variation, the modal distribution noise is suppressed.

Filed: 1982-02-16
Abstract: PURPOSE:To make a piece of paper feedable one after another with accuracy regardless of variation in the density of copying paper, by setting the position of a rotary fulcrum for an inward movable tray at the almost central part of the copying paper and while sandwiching this rotary fulcrum, installing a weight in a tray position opposite to the setting position of a feed roller. CONSTITUTION:A pin 3 is projectingly inserted through in both outer surfaces of an inward movable tray 2 where a pile of copying paper 1 is held in, and the inward movable tray 2 is rockably pivoted in an outer tray 4 via the pin 3. At this time, the pin 3 is to be set in a position where distance 11 and distance 12 reaching both ends of the copying paper from the center of the pin 3 come equaled. On the other hand, a weight 5 is installed in the rear end of the inward movable tray 2 and thereby pressure P of the copying paper 1 to be imposed on a feed roller 6 disposed near the front end of the inward movable tray 2 is almost uniformly kept up by means of each moment of the weight 5 and the tray 2 with respect to the pin 3. According to this method, even when the density of the copying paper 1 alters, pressure of the feed roller 6 to be imposed on the copying paper remains unchanged, so that the copying paper can be accurately fed piece by piece in regular sequence.

Abstract: PURPOSE:To improve heat collecting efficiency of a heat-pipe type vacuum tube system solar heat collector, by connecting a metal end plug, which is mounted on the end part of a vacuum glass tube, and a heat exchanger as a unitary body, and providing said heat exchanger in the vacuum glass tube. CONSTITUTION:An end plug 8 made of metal, which is mounted on the end of a vacuum glass tube 1, and a heat exchanger 4' are connected as a unitary body, and the heat exchanger 4' is sealed in the vacuum glass tube. Therefore the quantity of heat, which is conducted to atmosphere through the glass tube from the heat exchanger is minute. Since members, which are contacted with the atmosphere and radiate heat, are only the end plug 8 and a connecting pipe 7, both members are covered by a heat insulating material, and shielded. Then, even though the pipe 7 and a heat insulating cover 5 are made compact and heat collecting efficiency is improved, the amount of heat radiation can be suppressed to a lower value.

Title: Airflow direction changing device for air conditioner
Inventor: NARIAI SHIGERU
IPC: F24F13/08
Filed: 1984-02-09
Abstract: PURPOSE:To permit to change the direction of airflow so that warm-air is blown off downwardly upon room heating and cool air is blown off upwardly upon room cooling respectively by a method wherein a resistance plate is moved by utilizing the strain of a shape memory alloy upon room cooling and room heating, which is caused by the property of deformation of the two-directional shape memory alloy. CONSTITUTION:A SMA (shape memory alloy) spring 4 is elongated by delta due to the property of deformation thereof upon heating operation and the resistance plate 2 moves forward. The stream of air above a slide shaft is the stream d1, flowing along the inner surface of a duct grille 1, and the stream d2, flowing along the slide shaft. In the stream below the slide shaft, the stream d3, flowing along the slide shaft, is generated but the stream d4, flowing along the inner surface of the duct grille 1, is intercepted by the resistance plate 2 and the pressure thereof is reduced. Further, the stream d1 flows downwardly from an outlet port, therefore, ventilating airflow D0 is blown off downwardly. The SMA spring 4 contracts by delta due to the property of deformation thereof upon cooling operation. According to the contraction of the spring 4, the streams are different from the same upon heating operation and they become symmetrical below and above the slide shaft 5 such as the streams e1-e4 and, therefore, the pressure of the streams are equal in the upper and lower streams and the ventilating direction E0 becomes the blow-off of horizontal direction.
