Title: Short time tempering method for steel
Inventor: ONOUE YASUMITSU
IPC: C21D1/18
Filed: 1981-11-16
Abstract: PURPOSE:To reduce the time for heat treatments in the state of tempering of thick steel plates to be hardened and tempered by setting the temp. of a furnace at a temp. higher than the target tempering temp., and ending the tempering when the central temp. of the steel plates attains the desired tempering temp. CONSTITUTION:Steel plates are inserted into a furnace of which the atmosphere is set at >=700 deg.C. When the central temp. of the steel plates attains a desired temp., the steel plates are removed immediately from the furnace. Then larger differences than those in the prior art are produced in the surface parts and central parts of the steel plates between the tempering stage and the time when the tempering ends; the temp. is higher in the surface parts. Therefore the allowances for the decrease in the surface hardness occured in the stage of hardening by tempering increase and eventually the hardness distributions in the thickness direction when the tempering ends flatten equal to or more than those in the prior art. Here the reason for limiting the furnace temp. lies in that the steel plates are heated in a shorter time. The higher furnace temp. is more preferable, but ordinary tempering temp. is lower than Ac1 and the purpose for said limitation is to heat the plates in the time shorter than that at said temp. The upper limit of the furnace temp. is determined by restrictions in the construction and equipment of the furnace.

Title: Manufacture of soi
Inventor: KUNIO TAKEMITSU
IPC: H01L21/20
Filed: 1984-09-04
Abstract: PURPOSE:To easily fabricate a SOI having no electrical characteristic deterioration and including an element active region containing no crystal grain boundary by setting the reflection factors to laser light of the insulating film formed on a substrate and of the insulating film of the element active region to predetermined ones. CONSTITUTION:On an SiO2 insulating film 8 of a predetermined thickness on an Si substrate 7, polycrystalline Si 9 which becomes an active element region is formed by a process such as CVD. The surface of the polycrystalline Si 9 is covered with an insulating film by thermal oxidation. Further, a gate electrode 11 of polycrystalline Si is formed, and the electrode 11 is covered with an SiO2 insulating film 12 of a predetermined thickness by thermal oxidation, whereby a SOI is fabricated. As a result, the reflection factor to laser light of the film 12 and the like becomes greater than that of the film 8 because of the difference in film thickness between the film 8 and the film 12 and the like. Thus, when the SOI is subjected to an annealing process by irradiation of +Ar laser light, the temperature of the gate region of the active element region becomes low as compared with other regions so that no crystal grains enters the gate region, thereby to prevent deterioration of the electrical characteristic. As a result, a SOI having no electrical characteristic deterioration can easily be fabricated.

Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a display tag which is hardly dislodged in spite of simple mounting, allows trial playing even if this tag is not removed and does not impair of the appearance of display contents by providing the tag with two holes for insertion of strings and two notches discretely formed across the peripheral edge of a detaining part from the respective holes. SOLUTION: The detaining part 1 has the two holes 1a formed apart a spacing between the two adjacent strings of a stringed instrument to which the tag is mounted at the end to be successively disposed with a band part 2. The detaining part has the two notches 12b discretely formed toward the peripheral edge of the detaining part 1 from the respective holes 1a. The detaining force to the strings may be adjusted by adjusting the notching width of the portions of the notches 1b connecting to the holes 1a. More particularly the friction force of the strings and the holes 1a is stronger if the notching width is made narrower. As a result, the strings are made hardly removable from the holes 1a and, in addition, the sliding and subsequent shifting of the display tag A for the stringed instrument along the longitudinal direction of the strings are prevented.

Abstract: PURPOSE:To make it easy to guide a pinball ball to the space of a variable prize-winning device by reciprocating a rotating member between a first position to cause the pinball ball to be easy to flow from a notch into a space part and a second position to cause it to be hard to flow in. CONSTITUTION:In the opening condition (first position) of a rotating member 14, a shot ball is made easy to flow from a notch 12 into a space part 13. On the other hand, in the closed condition (second condition) of the rotating member 14, the shot ball is prevented from flowing from the notch 12 into the space part 13. When the pinball ball to flow into the space part 13 wins a prize to a successive prize-winning port 18, a big prize winning processing is executed. At such a time, the rotating member 14 is rotated by a drive control means 15 and, simultaneously, reciprocated for a prescribed time between the first position and second position by a moving means 16. For such a reason, the rotating member 14 causes the pinball ball to be easy to flow from a game board into the space part 13 of a variable prize-winning device 11 by the above- mentioned rotation by the drive control means 15.

Filed: 1987-07-22
Abstract: PURPOSE:To obtain a magnetic head with which sliding with a tape is good by inclining gap-facing surfaces by + or -20-60 deg. at the time of formation of thin magnetic films and forming the thin films thereon from two directions, thereby forming the thin magnetic films having dense structure on the side faces of truck grooves. CONSTITUTION:The gap-facing surface 4 as well as the track grooves 6 and winding groove are formed on a block of a magnetic oxide material and thereafter, the thin magnetic film 10 is formed on the surface 4 by a sputtering method. The surface 4 is inclined by theta1 deg. (+20-60 deg.) with respect to a direction 8 where sputtering particles enter. The thin film having the thickness of half the prescribed film thickness is then formed on such surface. The surface 4 is thereafter inclined by theta2 deg. (-20-60 deg.) in the opposite direction and the film is formed thereon to the remaining film thickness. The dense thin film is thus formed even on the surfaces 9 perpendicular to the gap-facing surface and the taking of the thin magnetic film on the side faces 9 of the track grooves into the glass is obviated at the time of packing the glass into the track grooves. The magnetic head wit which the sliding with the tape is good is thus obtd.

IPC: H01L21/321
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To prevent excessive pressure from being applied on an insulating film disposed under a protruded electrode of a semiconductor chip and a connection pad when the protruded electrode of the semiconductor chip is bonded to the connection pad, etc., on a circuit board under pressure. SOLUTION: An insulating resin layer 15 comprising polyimide and the like is formed on an upper surface of a connection pad 12 exposed through an opening 14 in an insulating film 13 at the center of the same, and a lower protruded electrode 20 is formed on the connection pad 12 including the insulating resin layer 15 and on the insulating film 13 around the connection pad 12 through a diffusion prevention layer 16 and a bonding layer 17. An upper protruded electrode 23 is formed on the lower protruded electrode 20 at a portion corresponding to the center of the insulating resin layer 15. Since a flat plane size of the upper protruded electrode 23 is small, pressure required for bonding may be small.  Further, the pressure is dispersed owing to the lower protruded electrode 20 having a large flat plane size, and is moderated because the insulating resin layer 15 under the lower protruded electrode 20 is compressed and deformed.
