Title: Production of fluid catalyst carried on alumina base material
Inventor: SHIRAGAMI KEN
IPC: B01J23/84
Filed: 1987-11-16
Abstract: PURPOSE:To improve the wear resistance of a fluid catalyst by spray-drying a slurry contg. a metal component and alumina as a carrier component wherein said slurry is pulverized by a wet process to >=0.35mum mean particle size, then calcining the spray-dried particles. CONSTITUTION:A slurry contg. alumina as carrier component and a metal component is pulverized until >=0.35mum mean particle size is attained, by a wet process. A fluid catalyst formed on alumina base carrier is produced by spray-drying the pulverized slurry and calcining. Preferred alumina for the carrier component is gamma-alumina, and preferred metal element in the metal component is Fe group metal in combination with Mn, or Fe group metal in combination with Mn and Pt group metal. Said metal component is carried by the alumina carrier usually in the formed of oxide. Although the method for pulverization is not critical, deterioration of wear resistance may occur when the mean particle size of pulverized particles exceeds 0.35mum.

IPC: H04L23/00
Filed: 1985-12-20
Abstract: PURPOSE:To reduce the data volume of document information and to shorten the data transmission time by expressing the continuity of one-character spaces or the same characters or symbols with a code indicating the continuity of them and a code indicating the number of continuance of them. CONSTITUTION:The format (omitted in the figure) encoded with only format control functions defined by 'Japanese telex equipment recommending communication system' and the format encoded by this inverted method as shown in the figure are compared with each other. When spaces corresponding to 5 characters are continuous from the start character position of a line like a line l3 and l16, they are expressed with 'ESP', 'SP, and '5' in the invented method and the data volume is reduced by a data volume (normally two bytes) corresponding to two-character code data in comparison with the conventional method though 5 'SP's are continuous in the conventional method. When 10 one-character spaces are continuous from the start character position of a line like lines l6, 7,...15 and lines l17, l18..., the data quantity is reduced by a data quantity (normally, 7 bytes) corresponding to 7-character code data.

Title: Reflection type projector
Inventor: KITAI KENICHI
IPC: G02F1/136
Filed: 1989-11-07
Abstract: PURPOSE:To form the projector to a smaller size and lighter weight and to obtain a projected image which is higher in grade and is uniform by providing a plate member which is adhered or press-welded to the rear surface of an active matrix substrate and has the thermal conductivity higher than the thermal conductivity of the active matrix and a mechanism for cooling the plate member by the forced air flow of the machine body. CONSTITUTION:The plate member 5 having the thermal conductivity higher than the thermal conductivity of the semiconductor substrate 3 is press-welded to an LCD 1 having the semiconductor substrate 3 as one substrate. The plate member 5 is formed by forming a heat sink on the side face of a thick film plate consisting of beryllia (BeO), silicon carbide (SiC), copper (Cu), molybdenum (Mo), etc., then thinly cutting the part to be press-welded with the LCD 1 by a milling machine, etc. The forced air flow 8 from an axial fan 7 deprives the plate member 5, which is formed thin in order to reduce the thermal resistance of the conduction part, of heat and thereafter the air flow absorbs the further larger heat quantity by the large area and velocity of flow in the heat sink part. The small-sized and lightweight reflection type projector having the high luminance and grade is formed in this way.

The absorbing strength of aluminum carboxylate per one reflection by an infrared spectroscopic method at the interface between the plastic film and the aluminum oxide thin film is not less than 5×10<-5> . The absorbing strength lower than 5×10<-5> makes the gas barrier performance insufficient.
