Title: Preparation of imidazole compound
Inventor: MATSUI KIYOHIDE
IPC: C07D233/58
Filed: 1981-02-17
Abstract: PURPOSE: To prepare the titled compound having wide application range in pharmaceuticals and pesticides, etc., simply by reacting an easily available carboxylic acid amide with an alkoxyethylamine derivative which can be prepared easily by the reaction of a chloroacetal derivative with ammonia.  
     CONSTITUTION: The imidazole compound of formula III (R 1  is H, alkyl or  phenyl)(e.g. imidazole) can be prepared by reacting (A) 1 equivalent of the alkoxyethylamine derivative of formulaI(R is alkyl or two Rs together form alkylene)(e.g. 2,2-diethoxy-ethylamine) with (B) 2.5W6 equivalent of the carboxylic acid amide derivative of formula II (e.g. formamide), while removing the by- products from the reaction system. Since no solvent is used in the reaction, the objective compound can be separated by direct distillation.  
     EFFECT: The post-treatment is also extremely simple.

Title: Granular powder unloading and feeding apparatus
Inventor: SUWA HIDEYUKI
IPC: B65G17/12
Filed: 1984-02-09
Abstract: PURPOSE:To reduce power consumption and to attain large unloading and feeding capacity by disposing a rotor with baldes in such a manner as to face a take-in port on casing side below a conveyer casing in an apparatus for unloading and feeding granular powder from a hold. CONSTITUTION:A conveyer 22 and a rotor 32 are rotated to lower the lower end of the conveyer onto granular powder 14 in a hold. Thus, the granular powder 14 is forced to flow in a take-in port 40 by its gravity and accelerated by blades 34 of the rotor 32 to be fed into the case of the conveyer 22 by centrifugal force. At this time, the taken-in granular powder 14 is accelerated to be substantially equal to the peripheral speed of the forward end of the blade 34. Therefore, the rotational frequency of the blade 34 is suitably set to accomplish proper transport. This arrangement can reduce an apparatus to a compact size, reduce power consumption and enlarge unloading and feeding capacity.

Abstract: PURPOSE:To eliminate the need for a high-output howler tone generator provided to a subscriber circuit, by amplifying a howler tone, sent from a signal tone trunk via an electronic switch, at the subscriber circuit and sending the amplified tone to a telephone set. CONSTITUTION:A signal tone trunk TNT equipped with a low-output howler tone oscillator HW' is connected to a subscriber circuit LC' via an electronic switch TDSW.

CONSTITUTION:A long fiber of polyethylene terephthalate having a thickness of 5 to 25 denier is prepd. In bonding the long fiber with an adhesive component to prepare a nonwoven fabric, the long fiber is oriented so as to form such an orthogonally oriented structure that the sum of cross-sectional areas occupied by fibers having a length to width diameter ratio of 80 to 120% in each cross section in the longitudinal direction and the width direction of the nonwoven fabric is not less than 50% based on the sum of cross-sectional areas of the whole fiber, and the weight per unit area is brought to 20 to 200 g/m<2>. The nonwoven fabric of a long fiber of polyethylene terephthalate is used as a reinforcement for foam molding of urethane. The reinforcement causes no uncomfortable frictional sound because the foamed polyurethane resin does not substantially leak to the opposite side of the nonwoven fabric Further, it has excellent tensile strength and other properties.
