Title: Brazing method for al or al alloy
Inventor: YAMAGUCHI MOTOYOSHI
IPC: B23K35/363
Filed: 1988-12-23
Abstract: PURPOSE:To improve brazability and to storten the working process by applying a potassium fluoroaluminate complex on a part of a joint part and brazing these parts in a nonoxidative atmosphere where the vapor of the complex exists. CONSTITUTION:The potassium fluoroaluminate complex is applied on a part of the joint part of a member to be brazed and the other member is not coated with the potassium fluoroaluminate complex. These members are brazed in the nonoxidative atmosphere where the vapor of the complex exists. The vapor sticks in an extremely slight amt. and uniformly to the assembly and breaks the oxide film of the Al on the surface thereof, thereby accelerates the wetting of the solder. The solder flows uniformly and the uniform fillets are formed in the joint point of the assembly. Further, this vapor combines with the moisture and oxygen in the atmosphere to make the atmosphere more nonoxidative, thereby prevent the oxidation of the material surface.

Abstract: PURPOSE:To protect the clean surface of an epitaxial wafer from physical or chemical pollution and improve reliability by forming a thin oxide film at the surface of the epitaxial wafer while holding it in oxidizing atmosphere. CONSTITUTION:A silicon wafer 2 is placed on the susceptor 1 inside an epitaxial growth furnace, and after temperature rise to, for example, 1200 deg.C in hydrogen atmosphere, the surface of the silicon wafer 2 is cleaned by hydrochloric acid gas etching. Next, successively a specified epitaxial layer 3 is grown by silicon tetrachloride gas + dopant gas. Next, the furnace is powered off to lower the temperature, and at the point of time when the temperature inside the furnace becomes 400 deg.C or below, the atmosphere is once displaced from hydrogen gas to nitrogen gas, and successively oxygen gas is mixed in, whereupon an oxide film at the level of a thin natural oxide film is formed. And by the existence of the film 4, the surface of the wafer can be protected from external pollutive factors after takeout from the epitaxial growth furnace, and the clean silicon surface can be maintained as it is, so the deterioration of electric properties does not occur, and reliability can be improved.

Filed: 1991-12-09
Abstract: PURPOSE:To recycle offset preventing liquid without causing clogging in a sucking tube by depositing and separating toner and paper powder in the recovered offset preventing liquid in an oil tank provided with plural storage parts which communicate at an upper position. CONSTITUTION:The oil tank 10 is integrally constituted by allowing three storage parts 10a, 10b and 10c to successively communicate.

IPC: G01J9/02
Filed: 1988-12-20
Abstract: PURPOSE:To detect frequency difference between two light beams having different frequencies with high sensitivity by providing a half mirror, a photoelectric converter and a differential amplifier. CONSTITUTION:The light beam emitted from semiconductor lasers 1a and 1b is made to pass condensing lenses 2a and 2b to obtain the collimated beams of light, which are mixed by the half mirror 3a. After the mixed light is conducted to an optical path 4a, it is splitted by the half mirror 3b. Next, one of the splitted light beams passes through an optical path 4b and is inputted in the photoelectric converter 5a. The other of the splitted light beams passes through the optical path 4c and is reflected by the half mirror 3c, then it is inputted in the photoelectric converter 5b after passing through the optical path 4d. Therefore, the difference output of the converters 5a and 5b is obtained by inputting the output from the converters 5a and 5b in the differential amplifier 6. In order to make the output of the amplifier 6 a maximum value when the frequency difference of the light beams from the lasers 1a and 1b is 1GHz, for example, a previously set reference frequency f0 is set at 1GHz and the length difference of the optical paths Z is set at a value obtained from Z=(n+1/2)lambda0. Provided that lambda0 is the wavelength of the light with the frequency f0 and (n) is a positive integer.

Abstract: PURPOSE:To facilitate the assembly of a set of oil rings onto a piston by pushing out a side rail ring from the front end of a guide member in such a condition that spacer rings are restrained so as to prevent joint parts of a spacer ring from being superposed with each other at the inner peripheral surface of the guide member. CONSTITUTION:A push rod of a first pressing member is elevated while a pawl piece 103 is stayed at a lower end position, and a guide member 7 is elevated by the urging force of a washer. When the lower end of the guide member 7 is moved above a second spacer retainer 11P, the second spacer retainer 11P is projected inward by an urging force of a spring of a rod linked to the first spacer retainer 116, and when the guide member 7 is elevated up to a first fitting position, a side rail ring R is pushed out from the lower end of the guide member 7, and is assembled in an upper groove part GU. In this case, a second restraining means 117 inhibits joint parts of a spacer ring S from being superposed with each other due to a shock during the assembly of the side rail ring R.
