Title: Method and apparatus for continuous carburization
Inventor: MUKAI HIROYA
IPC: C21D9/56
Filed: 1986-07-10
Abstract: PURPOSE:To form a carburized layer on the surface of steel products with the thermal energy consumption and cost lower than heretofore by constituting a continuous carburization device for steel products of a 1st heating chamber for carburization, cooling chamber, 2nd heating chamber, hardening oil tank, and 3rd heating chamber for tempering. CONSTITUTION:A long-sized steel sheet or the like enters the 1st heating chamber 2 through a purging chamber 1 of gaseous N2 atmosphere as an inert gas and is heated to 850-950 deg.C in the chamber contg. gaseous CO or hydrocarbon at the atmosphere gas, by which the steel surface is carburized at the time of subjecting the surface of said steel sheet continuously to the carburization treatment. The steel sheet enters the cooling chamber 4 past a purging chamber 3 of the N2 atmosphere and is cooled down to the Ar1 transformation point in the gaseous N2 atmosphere. Such steel sheet enters again the 2nd heating chamber 6 through a purging chamber 5 and is reheated to 800-900 deg.C at the Ac3 or Acm point in the non- decarburizable atmosphere gas without oxidation. The heated steel sheet is immersed into the hardening oil tank 7 and is hardened by quick cooling down to the martensite transformation end temp. or below; thereafter, the steel sheet is subjected to the tempering treatment at the temp. below the Ac1 transformation point in the 3rd heating chamber 8. The carburization treatment of the steel sheet is executed with the heat energy lower than in the conventional method.

Filed: 1978-12-26
Abstract: PURPOSE: To make the size of bump electrode uniform inside a wafer by forming a bump electrode by the jet metal plating method prior to constitution of a rear surface electrode.  
     CONSTITUTION: A p-layer is built by laminating oxidized film 2 on wafer 1 composed of n - -layer on which n + -layer is piled as usual. Next, Au evaporated film 3 is formed only on the front surface and wafer 1 is mounted on support 13 with the front surface turned upside down. Then Ag sheet 20 is placed right on the rear surface of wafer, employing Ag metal plating liquid as positive potential and jet metal plating is carried out with the Ag sheet as negative potential. As a result, bump electrode 4 of the same size is constituted on the Au film 3, but no Ag metal-plated film is formed on the rear or side surface. In this way, the height of bump electrode can be made uniform within a wafer.

A disc 1 is tilted round vertical shaft by the same motor 9 also followed by irradiation with ions. Accordingly a source and drain are formed in the state of spreading with depth proceeding in a wafer, and the symmetry to the left and right is secured. Then the disc 1 fitted with wafer 2 is tilted by a motor 5 a certain angle round the horizontal axis to be put in the condition with channeling preventive angle, followed by irradiation with ions. If thereafter tilting is made by the motor 5 and ion implantation is performed, the ions are implanted as spreading with depth proceeding. This ensures symmetricity even in the vertical direction.

Title: Method and device for measuring stress in body
Inventor: ABE TETSUHARU
IPC: G01L1/00
Filed: 1984-08-03
Abstract: PURPOSE:To measure the internal stress distribution in a body to be measured which has a uniform shape and stress distribution in one direction at a high speed without destruction by measuring the optical path difference of light transmitted through the object body due to opto-elastic effect while rotating the object body. CONSTITUTION:The body 4 to be measured is fixed on a sample turntable 5, whose angle of rotation is set to some angle. In this state, laser light from a laser 1 which is polarized linearly by a polarizer 3 is allowed to strike the body 4 to be measured. This incident light is split into two components having mutually orthogonal planes of polarization by birefringence originating from the stress distribution in the body and they travel at different propagation speeds, so light passed through the body has an optical path difference and becomes an elliptic polarized wave. Further, the object body 4 has a uniform and stress in a direction Z and the light beam having this optical path difference is passed through a quarter-wavelength plate 7 to become linear polarized light. For the purpose, the optical axis of an analyzer 8 is rotated to read data on a vidicon 9 in an image memory 10 and the optical path difference is calculated by using a computer 11. Thus, a measurement is taken easily and precisely without destruction.
