Title: Method and apparatus for separating oil from water by coarsening
Inventor: SAKAI UTAROU
IPC: B01D17/04
Filed: 1980-07-31
Abstract: PURPOSE: To promote the coarsening of oil as well as pevent the clogging of pathways by alternately passing an oil-containing water through the surface and back pathways of a coarsening element provided with an oil-resistant and repellent layer and a water-permeating and absorbing layer.  
     CONSTITUTION: A coarsening device 7 for oil consists of a coarsening device 8 having porous elements 17 and 18 whose surfaces are provided with an oil-resistant and repellent layer and a water-permeating and absorbing layer, having a water- insoluble and absorbing gel layer mainly. The oil-containing water is flowed in the direction of A→B or B→A by switching a switch valve 9 and then passed through porous elements 17 and 18, during which oils are made into coarse oil droplets. At this time, the clogging of pathways with coarse oil droplets can be prevented because pathways for oil-containing water are altered toward the surface or the back side of the porous elements 17 and 18.

Title: Method for joining metallic members
Inventor: NOMURA SEIJI
IPC: B23K11/34
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To execute a good joining by joining with the heat generation and the heating according to the electric conduction between a first metallic member and a second metallic member under the surface contacting state so that the contacting surface beforehand becomes a specific value. SOLUTION: The electric conduction and the pressurization are beforehand executed under the surface contacting state between the first joining surface part 3a of a valve seat 3 and the second joining surface part 2a of a cylinder head main body 2. In such a case, the surface contact is indicated to be 400-200 mm<2> contacting area. Then, a material of the valve seat 3 is made of a sintered material, in which Fe base powder raw material obtd. by dispersing Cu as an element having high electric conductivity is sintered so as to be joined without fusing/infiltrating Cu base material into the pores in the inner part thereof. Therefore, even if the pores exist, the resistance value of the valve seat 3 can be restrained to be low with the Cu beforehand dispersed as the same degree as the material obtd. by fusing/infiltrating the Cu base material.  In this result, the heat generation in the inner part at the time of applying the power is restrained and the joining can be executed in good condition.

Abstract: PURPOSE:To eliminate the need for an exclusive switch for storage release, by constituting so that photometric information stored in advance is released in response to switching of a photographing mode. CONSTITUTION:Mean photometric voltage V1 of an analog value corresponding to luminance of an object to be photographed, from a mean photometric circuit, or spot photometric voltage V2 of an analog value corresponding to luminance of an object to be photographed from a spot photometric circuit is supplied to an information processing circuit 21. Subsequently, in the processing circuit 21, each photometric voltage is digitally converted, and after that, is stored as photometric information in a memory in a CPU24. Subsequently, when the photographing mode is switched, it is detected by the CPU24, and the photometric information stored already is cleared. In this way, the photometric information stored already is released by only switching the photographing mode, therefore, an exclusive storage releasing switch can be eliminated.

Title: Ultrasonic-wave flaw detecting method
Inventor: IWAMOTO KEIICHI
IPC: G01N29/04
Filed: 1990-04-24
Abstract: PURPOSE:To make it possible to detect a crack which is formed on the inner surface of a furnace wall pipe at the outside of a furnace from the inner side of the furnace by vertically sending an ultrasonic wave from the outer surface of the pipe at the opposite side of a part to be inspected from an ultrasonic wave probe, and detecting the flaw of the crack based on the attenuating amount of the ultrasonic wave. CONSTITUTION:A furnace wall pipe 2 is filled with, e.g. water 5, as a medium for transmitting an ultrasonic wave. A crack which is formed on the inner wall surface of the pipe at the outside of a furnace is detected. For this purpose, a vertical ultrasonic-wave probe 6 is brought into contact with the opposite side of a part to be inspected, i.e. the outer surface of the pipe on the inner side of the furnace. When the ultrasonic wave is inputted from the probe 6, the ultrasonic wave is propagated from the inner side of the furnace wall pipe 2 with respect to the furnace to the pipe wall on the outside of the furnace through the water 5 filled in the furnace wall pipe 2. Thus the ultrasonic wave reaches the part to be inspected. Then the ultrasonic wave which has reached the part to be inspected is reflected from the part to be inspected, propagated through the part in the reverse direction and returned to the probe 6. The crack is detected based on the attenuated amount of the returned ultrasonic wave.
