Title: Production of fluorosulfonic acid
Inventor: NAGAO TAMOTSU
IPC: C01B17/46
Filed: 1979-03-22
Abstract: PURPOSE: To obtain fluorosulfonic acid safely and economically by allowing sulfuric anhydride to be absorbed in fluorosulfonic acid; blowing gaseous hydrofluoric anhydride in amts. about equimolar with the sulfuric anhydride; and reacting them.  
     CONSTITUTION: Liquid or gaseous sulfuric anhydride is allowed to be dissolution- absorbed in liquid fluorosulfonic acid kept at about 20W40°C. Gaseous hydrofluoric anhydride is then slowly blown into the fluorosulfonic acid with the sulfuric anhydride absorbed in a SO 3  to HF molar ratio of about 1, e.g., 0.9W1.1, and it is reacted with the sulfuric anhydride to form fluorosulfonic acid. This reaction can be performed continuously. Fluorosulfonic acid and sulfuric anhydride are fed quantitatively and continously to an absorption vessel equipped with a cooler, and the fluorosulfonic acid with the sulfuric anhydride absorbed is allowed to overflow into a reaction vessel, where gaseous hydrofluoric anhydride corresponding to the sulfuric anhydride is blown quantitatively and continuously and reacted with the sulfuric anhydride to form fluorosulfonic acid.

Title: Unit for extrusion molding of tubular member
Inventor: HORIUCHI NOBUO
IPC: B29C48/09
Filed: 1986-02-20
Abstract: PURPOSE:To enable preparation of a tubular member having longitudinally uniform size as well as having small diameter, by providing a scaling up path part and a scaling down path part near the tip end part of a resin flow path. CONSTITUTION:Near the tip end part of a resin flow path 13 there are provided a scaling up flow path part 18 whose inner and outer diameters become gradually larger toward the outlet, and a scaling down flow path part 19 whose inner and outer diameters become gradually smaller, and an outlet flow path part 20 is provided following them. In the course where a resin passes through the scaling up flow path part 18, its pressure is lowered. Then in the course passing through the scaling down flow path part 19 the pressure rises; as the outlet is near, the degree of rise is restrained and it is extruded from the outlet. As the result, it is possible to mold by extrusion of the tubular member of stabilized size because of reduced amount of the resin spread to radial direction at the time of extrusion from the outlet, and the resin deposit under bonding to the edge faces of a die 11 and a nipple 12, and because the outlet of a gas supply hole 14 is not closed. As the diameter of the outlet flow path part can be freely set, the molding of the tubular member of small diameter is also possible.

Filed: 1981-03-10
Abstract: PURPOSE:To always ensure the accurate control of the toner density with high sensitivity and with a compact and simple constitution, by detecting the toner density of the developer and then controlling the toner supply device in accordance with the toner density. CONSTITUTION:A developer 1 applied to a latent image on the surface of a photoreceptor 20, and the developer which is not applied to the drum 20 is circulated again through the sensor part 30 of a toner density detector/controller. The both-end voltage VC of a capacitor C35 of the part 30 is usually set equal to the power supply voltage VP and then lowered when the signal is delivered from a sampling pulse producer 43 of a detecting circuit 40 to carry out the detection of the toner density. The reduction rate of the voltage VC differs in accordance with the resistance value of the developer 1 that flows on the surfaces of detecting electrodes 33 and 34 of the part 30. The change of the discharging time of the capacitor C35 is given to a comparator 47 via a comparator 45, a gate 46 and a time counter 44. Then a motor 50 is driven when the change of the discharging time of the C35 is shorter than the set time. Thus the toner is supplied to the developer 1.
