Abstract: PURPOSE:To improve yield of product of nitrogen gas without reducing its purity, by sending the product of nitrogen gas to a regenerated adsorption column adjusted to the same pressure as that of an adsorption column after adsorption, regenerating the adsorption column after adsorption process under reduced pressure. CONSTITUTION:A gas in the adsorption column 4a is made to flow in the bottom of the adsorption colum 4b after regeneration in vacuum. Simultaneously, at the initial stage, the valve 14 is opened, a product of nitrogen gas from the product tank 11 is fed to the top of the adsorption column 4b. When an outlet oxygen from the adsorption column 4a reaches a certain given tolerance value, the pressure of the adsorption column 4a and the adsorption column 4b is made equal through a pipe line passing through the valves 9, 12, and 13. In the operation, the valve 14 is in closed state. When the pressure of the two columns is made completely equilibrium in the operation, the valve 11 is closed, the valves 15 and 16 are opened, and the adsorption column 4a is regenerated by the vacuum pump 10. A raw material of pressurized air introduced in the adsorption column 4a is separated from oxygen which is adsorbed and removed, the raw material is made into the product of nitrogen gas, and sent to the product tank. The above- mentioned processes are repeated, consequently, the product of high-purity nitrogen gas is continuously prepared in high recovery ratio.

The grains for measurement charged into the hopper 36 are supplied onto the belt and intrude by each piece into the transporting holes of the belt 18 in the state in which the aperture at the bottom end of the hopper 36 faces the belt 18. Only the grains intruding into the transporting holes among the grains in the hopper 36 are embraced and transported upward by the movement of the belt 28 when the belt 18 is driven. These grains are supplied by each piece as the grains for measurement into the opposite spacing of the electrode rolls 16. The measurement of the moisture content of the grains by each piece is, therefore, possible. The workability of the measurement is improved in this way.

Abstract: PURPOSE:To realize the conversion of image resolution and to easily obtain a recorded picture of high quality with a low cost by giving the variable control to the modulated frequency of a light beam and also to the rotational speed of a rotary reflecting optical system. CONSTITUTION:An image resolution deciding means 100 is provided together with a picture element density conversion control means 200. The means 100 decides the image resolution of the received picture data during an incoming control procedure and at the same time the means 200 gives the variable control to the modulated frequency of a light beam as well as to the rotational speed of a rotary reflecting optical system based on the deciding result of the means 100. Therefore the image resolution of the picture data is converted in the main scanning direction by varying the modulated frequency of the light beam and also by varying the rotational speed of the rotary reflecting optical system for said variable control in the subscanning direction. Thus the rotational speed of a photosensitive drum can be fixed. Then the pictures can be recorded with high quality by the simple control without varying the process of an electrophotographic recording job.

Title: Production of silicon carbide sintered compact
Inventor: ASAYAMA MASAHIRO
IPC: C04B35/56
Filed: 1990-05-25
Abstract: PURPOSE:To sufficiently remove an impurity oxygen in SiC and improve sinterability by arranging deoxygenated members around a formed compact of SiC, temporarily sintering the compact in a vacuum, adsorbing the oxygen in the SiC on the deoxygenated members and carrying out normal sintering. CONSTITUTION:For example, a formed compact 1 of SiC and formed compacts 2 of aluminum nitride as deoxygenated members surrounding the formed compact 1 so as not to mutually contact are arranged in a sheath 3 made of carbon to carry out temporary sintering at 1650 deg.C in a vacuum. The formed compacts 2 are then removed from the interior of the sheath 3 to perform normal sintering at 2050-2150 deg.C. Thereby, silicon oxide in the SiC is released to the atmosphere by heating in the vacuum, adsorbed on the aluminum nitride and converted into aluminum oxide. Since the SiC raw material is purified to a high purity by releasing of the oxygen, sinterability is improved to enable reduction in the amount of a sintering assistant and sintering temperature. As a result, growth of grains following phase transition at high temperatures is reduced to provide the objective dense and high-strength sintered compact.

Filed: 1980-09-29
Abstract: PURPOSE:To use a normal access process as it is, by setting the number of times of access instruction and the access time in accordance with the ratio of the processing capacity. CONSTITUTION:When the processing capacity of an operator 12-B is 1/4 capacity of an operator 12-A, for example, normal access action is given to the operator 12-A through a control part 21. However, an instruction given to the operator 12-A is changed into four instructions (1-4) to the operator 12-B, and thus the access time is quadrupled for these instructions. As a result, the data to be taken into the operator 12-B is set with every four units like 1, 5, 9 and 13, and accordingly 2, 3, 4, 6, 7, 8, 10, 11, 12, 14, 15 and 16 must be taken for the residual instructions (2-4). For this purpose, the phases of the outgoing timing are shifted by an access time tau to each other for the instructions (2-4). As a result, all element data can be processed until the end of an instruction (4).
