Title: Diffusion brazing method for al or al alloy
Inventor: OOMAE TAKASHI
IPC: B23K35/30
Filed: 1981-05-08
Abstract: PURPOSE:To join Al or Al alloy by diffusion-brazing by using a foil of a material  which causes eutectic reaction with Al as an insert material, and heating the entire  part of a joint to the eutectic point or above. CONSTITUTION:The above-described insert material (e.g.; Cu, Ag, etc.) 3 is sandwiched  between joining materials 1 and 2 of Al or Al alloy, and the entire part of the joint is  heated in a vacuum atmosphere (or an inert gaseous atmosphere or the atmospheric  air). As a result, the atoms of the materials 1, 2 and the atoms of the material 3 are  diffused mutually and an eutectic compsn. alloy is formed at the joining interface.  This eutectic compsn. alloy has a lower m.p. than that of the materials 1, 2, and therefore if the entire part of the joint is heated to the eutectic point or above, for example, to around 600 deg.C, the eutectic compsn. alloy melts. As a result, the quantity of the  atoms of the material 3 in the molten layer is decreased by the diffusion of the atoms  of the material 3 from the molten layer to the joining materials and since the concn. of the atoms is maintained at the concn. of the liquidus line at that temp., the solid- liquid interface is moved in the direction of the molten layer, by which isothermal  solidification is caused, and this completes the joining. Here, 4 in the figure denotes a  vacuum chamber, 6 a shielding plate and 7 a heater respectively.

Title: Device controller
Inventor: YAMANAKA MINORU
IPC: F02B77/08
Filed: 1978-06-07
Abstract: PURPOSE:To accurately set the on-off setting point of a device controller of the device such as a negative pressure control valve, negative pressure switch or the like in an exhaust gas purifying system by providing relatively large hysteresis of the on-off operation. CONSTITUTION:When this device controller is applied for a negative pressure switch 20, signal negative pressure generated at a suction passage 10 is supplied through a check valve means 40 to a signal chamber 21 of the switch 20. When the negative pressure is enhanced to reach first predetermined value P1, the switch 20 operates to cause its contacts to become on. When the negative pressure is decreased then, the means 40 is closed since the valve plate 46 is urged to a sheet 47 by a spring 45 to thereby retain the negative pressure in the chamber 21 at first predetermined value P1. When the negative pressure reaches second predetermined value P2, the valve 63 of control valve means 50 is opened to cause the atmospheric air to be introduce through a port 53 into the chamber 21 to thus allow the switch 20 to be closed. Reference character H in Figure represents the magnitude of the hysteresis.

IPC: G01C3/06
Filed: 1983-04-18
Abstract: PURPOSE:To measure exactly a distance by providing a diffraction structure body in an optical system for projecting luminous flux for measuring distance, projecting plural diffracted lights generated by the structure body toward an object to be photographed, and photodetecting its reflected diffracted light by a photoelectric converter. CONSTITUTION:A light emitting source 3 rotates within some angle against a projecting lens 4, and a projecting luminous flux spot is scanned to a long distance side from a short distance side on the surface (ob) of an object to be photographed. The projecting luminous flux is diffracted by a diffraction grating 5, and a zero-order diffracted light 8 and + or - primary diffracted lights 10, 9 are generated. By changing an uneven quantity of the diffraction grating, it is also possible to make the intensity of three spots nearly equal, and when only the center part is mainly measured as to its distance, it is also possible to constitute so that there is a peak in the center spot, by weakening the + or - primary diffracted lights. The distance measuring range is expanded by a portion expanded horizontally of a distance measuring luminous flux 14, and the distance measuring luminous flux 14 can scan enough on the object to be photographed. In this way, a distance to the object to be photographed can be derived exactly.
