Title: Bellows forming method
Inventor: OOKA YUJI
IPC: B21D26/033
Filed: 1985-04-22
Abstract: PURPOSE:To unify the thickness after forming by forming a material in cylindrical seamless body and by forming the part to form the crest and root thicker than the part to form others. CONSTITUTION:A seamless tube is made by forming a material 1 in cylindrical shape with varying the plate thickness so that the part A in thickness t1 and length l1 and part B in thickness t2 and length l2 come alternately. Namely it is formed so as to make the plate thickness t1>t2. The bellows is made by forming this seamless tube so that the thicker part A becomes the crest and root. Namely the forming metal dies 2, 3 for crest and root are arranged alternately at the outer side of the thicker part A, a high internal pressure is applied and the bellows is made by forming with said pressure. The thickness reduction of the crest and root parts reducing most the thickness at forming time is thus eliminated and the bellows having a fixed thickness is uniformly obtd.

IPC: H01L21/265
Filed: 1983-05-17
Abstract: PURPOSE:To perform an effective annealing treatment by a method wherein an infrared lamp is employed and a specified heating schedule is adopted. CONSTITUTION:An ion implanted semiconductor substrate is retained in the atmosphere of an inert gas such as nitrogen gas. Preheating is carried out at a temperature of approximately 400-600 deg.C for a period of 10-30min by lighting up an infrared lamp for preheating. Both the sides of the semiconductor are instantaneously heated at a high temperature of approximately 700-1,000 deg.C for a period of 5-60sec at a high heating rate of 50 deg.C/sec or more by lighting up the infrared lamp for high-speed and high-temperature heating. Thereupon, while the cooling rate is controlled at a level of 50 deg.C/sec or more, the semiconductor is quickly cooled down to approximately 400-600 deg.C. The electrical activation of the impurity in the ion-implanted layer occurs at a value extremely approximate to the LSS theory regardless of the amount of the implanted ions, which fact is favorable in terms of characteristics.

Title: Working force measuring method and apparatus thereof
Inventor: FUJISAWA MASAYASU
IPC: G01L5/00
Filed: 1982-05-26
Abstract: PURPOSE:To measure a working force by detecting voltage of current flowing between an electrolytic liquid and a conductor during grinding. CONSTITUTION:When an electrolytic liquid (B) contacts metal A as illustrated, ions in the electrolytic liquid B shifts to the metal A depending on the difference between chemical potentials A1 and B1. When the surface of the metal A is ground with a grinding wheel, the voltage of current flowing between the metal A and the electrolytic liquid B changes depending on the condition of the surface of the metal A contacting the electrolytic liquid B. The condition of the surface of the metal A changes corresponding to the level of a working force applied thereon. Thus, the working force can be measured by detecting the voltage of current flowing between the metal A and the electrolytic liquid B.
