Title: Resistance welding method and its device
Inventor: SAWABE MASATOYO
IPC: B23K11/24
Filed: 1981-08-28
Abstract: PURPOSE:To obtain a uniform welding result, by adjusting a welding current and a welding time, and controlling an integral value of quantity of heat generated in a weld, to a prescribed value. CONSTITUTION:An operation controller 8 detects resistance between electrode chips at every semi-cycle, and compares it with a reference value of a cycle stored in a storage device 10. In the event of a variation, it is considered to have been caused by a variation of a resistance welding section, and in accordance with the detected resistance between the electrode chips, and the reference value, a reference welding current value of the following semi-cycle stored in the storage device 10 is calibrated, it is considered to be a new control target value, and also an ignition angle moving extent for setting the detected welding current value as this target value is derived by means of operation. As a result, an ignition angle of the following semi-cycle is decided, by which welding is executed. In this way, the sum total of an effective power value of the weld, that is to say, the total heating value is made constant, and a uniform welding result is obtained.

Title: Differential-pressure measuring apparatus
Inventor: KUWAYAMA HIDEKI
IPC: G01L13/06
Filed: 1990-05-28
Abstract: PURPOSE:To facilitate miniaturization and to prevent the deformation of the central part of a central diaphragm by providing an annular plate spring whose one surface is in contact with the central diaphragm, and providing a disk- shaped plate spring corresponding to the central hole part of the annular plate spring. CONSTITUTION:When excessive pressure is applied from the side of high pressure, an annular plate spring 22 and a central diaphragm 21 are brought into close contact. The plate spring 22 is subject to the force which is applied to the plate spring 22 and a disk-shaped plate spring 23, and the spring 22 is deformed. Meanwhile, the disk-shaped plate spring 23 is also deformed. When the deformation becomes a specified value or more, a liquid separating diaphragm 12 comes into close contact with a back plate 10A, and the pressure exceeding this value is not applied. At this time, since the stress of the annular plate spring has a ring pattern, the stress is largely decreased in comparison in the same amount of change. Therefore, the diameter of the annular plate spring 22 can be made small, and the compact configuration can be achieved.

Abstract: PURPOSE:To centrifugally separate solid particles from a solid particle- containing solution, by arranging a disc body which is fixed to the connection shaft provided to the upper part of a cylindrical container and has an outer diameter larger than that of the cylindrical container. CONSTITUTION:A solution receives centrifugal force and the insoluble residue therein is accumulated and collected on the inner wall of a cylindrical container 7 and the clarified solution is made to flow out to a receiving container 13 from a discharge port 11 and subsequently sent to the next extraction process from an outlet 13a.

Title: Production of phenolic resin
Inventor: KUSHIDA TAKANORI
IPC: C08G8/04
Filed: 1981-08-28
Abstract: PURPOSE:To obtain a phenolic resin having a low residual formaldehyde content and causing no problem on health or rust formation, by adding an amino compound at the end of the reaction of formaldehyde with a phenol. CONSTITUTION:In the production of a phenolic resin by reacting formaldehyde with a phenol, an amino compound is added at the end of the reaction (a period  which is just after the reaction and during which the temperature is about 103-105 deg.C is the most suitable). As the amino compound, urea is particularly preferred. The amount of the amino compound is properly selected according to the state of the condensation reaction, and it is usually 0.5-5wt%, based on the total charge. This amino compound reacts with unreacted formaldehyde and, in consequence, markedly decreases a residual formaldehyde content. The reaction mixture is then dehydrated to obtain a phenolic resin.
