Filed: 1977-11-12
Abstract: PURPOSE: To restore the composite oxide catalyst containing one or more kinds of metal including Sb, Fe, Cu and Ni once deteriorated in performance to a level equal to the new one in the yield and reaction velocity on the activated surface thereof by baking thereof within a given temperature range after immersed into or sprayed by nitric acid or a solution of nitrate (e.g. NH 4 NO 3 ).  
     CONSTITUTION: The composite oxide catalyst containing Sb previously deteriorated in the performance through application to exidation of hydrocarbons, ammoxidation or oxidizing dehydrogenation by the following procedure: The catalyst is immersed into or sprayed by nitric acid or a solution of nitrate (e.g. NH 4 CO 3 ) and then, allowed to dry. Subsequently, it is baked in a non-reductive atmosphere such as air at 400 to 1,000°C for regeneration. 0.01 to 50% by weight is preferable for the nitric acid or the solution of nitrate in the immersion of the catalyst to be treated.

Filed: 1984-06-29
Abstract: PURPOSE:To manufacture easily a titled hologram disk, and to improve its performance by sticking a transparent cover through a sealing layer to the upper face of a transparent substrate to which a recording layer has been adhered, fitting it to a ring of a material whose coefficient of thermal expansion is almost the same as that of the substrate, and sealing airtightly its gap. CONSTITUTION:On the upper face of a transparent substrate 22 consisting of glass, to which a recording layer 23 has been adhered, a cover 24 consisting of the same glass as the substrate 22 is stuck through a sealing layer 25. Subsequently, this cover is fitted to a ring 26 consisting of a material whose coefficient of thermal expansion is almost the same as that of the substrate 22, and its fitting gap is sealed airtightly by an adhesive agent layer 27 which has used a solder for glass or a silicone compound adhesive agent. In this way, the outside end face of the recording layer 23 is sealed by the adhesive agent layer 27, therefore, since the recording layer 23 can be formed on the whole upper face of the disk substrate 22, the peeling processing becomes unnecessary. Also, as for the adhesive agent layer 27, that of small moisture permeability can be used, therefore, the moisture resistance is improved. In this way, the manufacturing process is simplified, and the performance can be improved.

Title: Positive electrostatically chargeable toner
Inventor: UCHIYAMA MASAKI
IPC: G03G9/08
Filed: 1983-07-26
Abstract: PURPOSE:To improve the image density of the positive-chargeable toner to be used for electrophotography and electrostatic recording and to prevent photographic fog by incorporating a resin, coloring agent and specific compd. into said toner. CONSTITUTION:A resin, coloring agent and the compd. expressed by the formula are incorporated into a toner. The compd. expressed by the formula is particularly used as a positive charge control agent. Since the control agent is colorless, said agent is particularly suitable for a color toner and moreover said agent disperses well into the resin and therefore the uniformly charged toner is obtainable. The control agent is preferably compounded within a 1-1.5wt% range of the resin. Pigments such as carbon black and phthalocyanine and various dyes are used for the coloring agent. Various resins such as polystyren resin, acrylic resin are used for the above-described resin. If R2NCH2CH2X.HCl is used as the positive charge control agent, the compd. is colorless and has a high capacity of positive charge power and therefore the positive charge toner of a desired color is obtd. without spoiling the hue intrinsic to the coloring agent and the image having no photographic fog is obtd.

Filed: 1978-11-06
Abstract: PURPOSE: To reduce flow rate loss in the case of an underlap, to prevent hydraulic lock, and thereby to smoothen the sliding displacement of a spool by providing a land end portion of a spool or a port of a valve main body with a circumferential notch.  
     CONSTITUTION: When a valve spool 220 reaches the position shown in the figure in the course of its downward sliding displacement from an upper position, a second port 212 is communicated with a valve chamber 209 through a stepped circumferential notch 222a formed at the lower end of a medium-diametered land 222 and through a throttle passage which is formed by the land 222 and the control edge of the port 212. Assisted by the fact that dimensions are set as E>C>D, this communicating condition is maintained until the spool 220 undergoes a downward sliding displacement and a small-diametered land 223 opens a third port 213 to communicate the chamber 209 with the port 213. Therefore, the oil in the chamber 209  is not subjected to sealing compression by the land 222, and the spool 220 undergoes a smoothened sliding displacement.
