Title: Removing method of scale
Inventor: NAKAYAMA HARUO
IPC: F28G9/00
Filed: 1979-07-14
Abstract: PURPOSE: To maintain the dissolving power of the acid liquid added with a corrosion inhibitor and remove scale efficiently by filtering said acid liquid with a filter having been precoated with a powdered cation exchange resin, in removing scale by said acid liquid.  
     CONSTITUTION: In a method of removing scale of a boiler 1 or the like by the acid liquid added with a corrosion inhibitor, water is filled in the boiler, after which the water is circulated by a circulating pump 3 while being heated and is injected with an acid and a corrosion inhibitor etc. from a chemical feed tank 4 by a chemical feed pump 5, whereby it is made into the acid solution of a fixed concentration. This acid liquid is then passed and circulated through a filter 2 having been precoated with a powder ion exchange resin, whereby the pickling of the boiler 1 is accomplished. The above-mentioned precoating is accomplished by mixing the exchange resin and a fibrous filter aid to prevent the occurrence of cracking. In addition, a high-polymer electrolyte is added to the powdered cation exchange resin to give gaps to the precoating layer, thereby reducing air permeating resistance. Thus, even if the acid liquid of a low concentration used, its dissolving power is maintained by regenerating the acid liquid and the scale is removed with good efficiency.

Abstract: PURPOSE:To provide a door impact bar with high strength and toughness as a whole and cost reduction in manufacturing, by having a part which is symmetrical to the central axis of a pipe including a bending deformation neutral axis which is not quenched, and a bending abdomen part and a bending back part which is quenched. CONSTITUTION:A door impact bar is obtained by heating only a 60-90 deg. area in a circumferential direction and a 60-90 deg. area of its symmetrical position of a steel pipe 3 by means of high frequency heating, laser or the like, and by quenching the other areas at a prescribed temperature by means of water cooling or air cooling. The steel pipe 3 obtained is installed in a door so that the high-strength area 4 which is quenched may be disposed on an outer plate 1 side and an inner plate 2 side of the door, and the high-roughness area 5 which is not quenched may be disposed on the upper and lower sides in a perpendicular direction. As a result, effective strength distribution for static load is formed, and an impact bending load is applied, so it is possible to prevent the area of a neutral axis from being broken completely without any breakdown even if bending abdomen side or bending back side is broken.

Title: Communication equipment
Inventor: ADORIANUSU PETERU MARUCHIN MAR
IPC: G06F13/00
Filed: 1988-04-13
Abstract: A computer system comprises a number of stations which are interconnected by means of a clock bus wire (20) and a data bus wire (22) which both form a wired logic function of the signals generated thereon by the stations (32, 34). During the clock pulses, the signal on the data bus wire is stationary; it may change between the clock pulses. Start and stop conditions are formed by a signal combination between clock bus wire and data bus wire (60 and 62, respectively) which is not permissible in a data stream. If there is more than one master station so that a composite clock signal occurs on the clock bus wire, the clocks of the relevant master stations are each time resynchronized to the actual transitions in the composite clock signal.

Abstract: PURPOSE:To limit a location of a sample at the time of process completion by setting the number of scanning times to an odd number, of a sample passing through a process chamber provided in an intermediate part between two air lock chambers between which the sample reciprocates for ion irradiation, so as to complete the process. CONSTITUTION:The number of scanning times of a sample 2 passing through a sample chamber 8 is surely set to an odd number to complete a process. Accordingly, in the case where scanning is started at an air lock chamber 12, a location of the sample 2 at the time of process completion is limited in an air lock chamber 10 on the opposite side to that at the starting time. Consequently, searching in which of the air lock chambers the sample is located is not required when operation is shifted to a next stage so that device constitution can be simplified. Different types of work can be performed simultaneously in both the air lock chambers 10, 12 so that throughput of the device can be enhanced.
