Abstract: PURPOSE: To obtain a catalyst having superior initial activity, having strength and permitting abrasive cleaning by granulating specific raw material compounds, and firing these under specific conditions, then impregnating the same with nickel salt followed by calcining.  
     CONSTITUTION: Raw materials of total 100pts.wt. consisting of 19W30pts. wt. clay of ≤2wt% of iron oxide content, 65W80pts. wt. chamotte of ≤1.5wt% of iron oxide content, and 1W5 pts.wt. nickel oxide prepd. from nickel carbonate as a starting material are first mixed uniformly and disintegrated, fter which they are granulated to spherical shapes. Thence, the granules are fired at 1,200W 1,350°C so as to contain 0.05W2mol the residual NiO based on 1mol of the formed NiO.Al 2 O 3 , after which they are impregnated with a nickel salt soln., so that 2.2W5.5wt% basing on the carrier NiO is deposited. Thereafter these are calcined at 600W650°C. The resultant catalyst for modification of hydrocarbon by steam is highly strong, permits restoration of activity through abrasive cleaning and has superior low temp. activity.

IPC: B01D71/82
Filed: 1992-06-12
Abstract: PURPOSE:To provide the novel ether bond-introduced amphiphilic amine useful for stabilizing water-soluble polyanion or ion complex thin films produced on gas-water interfaces. CONSTITUTION:The amphiphilic amine of formula I (R1 is >=10C alkyl, fluorocarbon; R2, R3 are H, methyl;,4nFis 1-6) for forming thin films, e.g. a compound of formula II.

Filed: 1980-12-18
Abstract: PURPOSE:To miniaturize a current control element and thereby to reduce the cost therefore by improving the anode starting voltage starting characteristic and by reducing the load voltage of the control element immediately after the device is lighted up. CONSTITUTION:Before a laser tube 4 is lighted up, the output V0 of anode voltage dividing resistors 18 and 19 is equivalent to the output of a DC supply source 1. A switch 21 being closed, the output is amplified 14 through comparison with te reference voltage VS2 set 13 at a level higher than V0 and thereby a motor cylinder 16 is driven 15. Then, the bellows of a gas reservoir 17 is compressed and thereby the gas pressure of the laser tube 4 is raised. When the swtich 21 is opened simultaneously with the lighting-up of the tube 4, the anode current flows to a resistor 3, the output voltage Vm1 is turned into Vm2 through DC amplificaton 10 and amplifed 14 through comparison with the output V0 of the anode voltage dividing resistors 18 and 19 and thereby the belows is expanded to adjust the gas pressure. Therefore, the anode voltage is kept at a prescribed value with the improved anode voltage starting characteristic of the laser tube and the load voltage of the current control element 2 is kept below the  prescribed value in the course from just after the lighting-up to the stationary state. Accordingly, the breakdown voltage of the current control element can be selected to be low, thereby  the miniaturization and reduction of cost of the device are enables and also stable laser oscillation is obtained.

Abstract: PURPOSE:To place an original closely to image formation systems of a reader which reads picture information through the image formation systems, by irradiating the original with light through an optical path changing element group arranged among the image formation systems. CONSTITUTION:Mirror elements 51-53 are arranged among respective image formation systems 21-23 in one body, and those mirror elements 51-53 are so set that original irradiating light which is nearly in parallel to an original surface 4 is reflected by the mirrors at right angles to the original surface 4 to illuminate the original surface 4.

Title: Integrated circuit having oscillator, frequency of which can be varied apart from supply voltage
Inventor: JIYAN NIKORAI
IPC: H03K3/023
Filed: 1990-07-07
Abstract: PURPOSE: To make the oscillation frequency independent of a supply voltage by making the difference between high and low thresholds of a threshold comparator, which starts charging/discharging of a capacitor, proportional to the charging/discharging current of the capacitor. CONSTITUTION: A threshold comparator COMP1 has a function which stops charging or a capacitor C to start discharging at the time of arrival of its terminal voltage at a high threshold Vh, and a threshold comparator COMP2 stops discharging of the capacitor C to restart charging at the time of arrival of its terminal voltage at a low threshold Vb. A logic circuit CL outputs control signals or switches Kc and Kd, and its output S is the output of the oscillator also. Since comparators COMP1 and COMP2 are so constituted that the difference between thresholds Vh and Vb is proportional to a current I of a unit current source, the charging period and the discharging period are independent of a supply voltage Vcc. Thus, the oscillation frequency of the oscillator is fixed and is independent of the current variance due to the variance of the supply voltage.
