Title: Press treating device of long size work
Inventor: TASHIRO YASUHIRO
IPC: B21K1/12
Filed: 1989-03-30
Abstract: PURPOSE:To regulate the inside peripheral part of the middle hole of a boss part into a prescribed shape simultaneously with a press treating by accumulating an energy in an energizing member when die is clamped and mold-releasing a punch from the middle hole of the boss part with the accumulated energy when a movable part is kept away from a fixed die. CONSTITUTION:By lowering the movable part 3, a punching die 4 is inserted into the middle hole W3 of the boss part and inside burrs W4 which are left in the middle hole W3 are removed and the shape of the inside peripheral part of the middle hole W3 of the boss part is regulated. In that case, an elastomeric part 5 is compressed and deformed between a seat board 33 and a cover board 31 and the energy for mold release is accumulated in the elastomeric part 5. When the movable part 3 is lifted, a movable die 22 and the punch 4 are lifted, the cover board 31 also is lifted and the elastomeric part 5 is elongated in the axial direction and is restored to the original state. In that case, the punching die 4 is drawn out from the middle hole W3 of the boss part and the boss part of the blanc material W is mold-released from the punching die 4 while bringing the die face 201 of the movable die 20 into contact with the other end face 21 of the boss part of the raw material W.

Title: Thermal treatment of semiconductor wafer
Inventor: HASHIMOTO TSUYOSHI
IPC: H01L21/00
Filed: 1981-05-27
Abstract: PURPOSE:To apply inert gas treatment or impurity diffusion in wet condition to semiconductor wafers by performing oxygen-hydrogen combustion in a different area of the inside of a diffusion oven core tube from the area where semiconductor wafers exist. CONSTITUTION:Oxygen-hydrogen combustion is performed in a different area 22 of the inside of a diffusion oven core tube from the area 10 where semiconductor wafers exist. Only steam generated in the area 22 is introduced into the semiconductor wafers existing area 10 via a penetration hole 23 of a section board 21. At this time, inert gas or impurity gas 26 for diffusion is supplied directly into the semiconductor wafers existing area 10 and is mixed with the steam above mentioned and the semiconductor wafers are treated by heat. With this constitution, pure steam which contains almost no oxygen is generated and this steam is introduced into the semiconductor wafers existing area. Accordingly, the steam is mixed with inert gas or impurity gas for diffusion which are supplied directly to the above area, so that wett-annealing and diffusion can be performed.

Title: Testing of integrated circuit
Inventor: WATANABE FUKUYOSHI
IPC: H01L21/822
Filed: 1982-05-12
Abstract: PURPOSE:To simplify the switching between the test state and the normal state along with a reduced number of terminals by enabling the changeover of the test position to the normal position and vice versas utilizing an external lead terminal for the oscillation of ICs. CONSTITUTION:In the normal state, an internal signal R invariably turns to the level 'H' once during one cycle of an internal signal CP, resetting shift registers 12 and 13 and the internal test signal is left at the level 'L', where the test mode won't be turned on. Even if a clock is supplied from any outside source other than a quartz oscillation circuit, a change takes place on the XOUT side by a clock from the XIN side and the test mode won't be turned on. Thus, the normal state is maintained. On the other hand, when a testing is perfrmed, the terminal XIN is fixed at the level 'L', turning the reset signal R to the level 'L'. Then, a clock signal is fed forcibly from the terminal XOUT to turn the internal test signal QA to the level 'H' with a signal detection circuit comprising the shift registers 12 and 13. Thus, the test mode is turned ON.

Title: Character recognizing device
IPC: G06K9/20
Filed: 1992-04-01
Abstract: PURPOSE:To improve the precision of character recognition by determining the recognition order of a character area after expanding an index area so that the index area and a main text part adjoin to each other. CONSTITUTION:An index/main text classification part 7 detects the character sizes of respective character areas and their numbers of lines, investigates whether or not the number of lines is >=3 and the character size is equal to a made character size, and sets information as the index area when the number of lines is <3. The area detected as the index area is expanded by an index area expansion part 8 in the character string direction of the index area to an extent where it does not overlap with any other area, thereby expanding the index area. Thus, index sentences and main text sentences are classified and the index area is expanded so that the area of the index sentences is always adjacent and the index does not overlap with any other area; and then the adjacency relation between the index area and main text area is checked and the order of character recognition is determined according to the adjacency relation.

Title: Veneer with grain pattern and manufacture thereof
Inventor: MURAKAMI HIROAKI
IPC: B27D5/00
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To manufacture a veneer with a grain pattern having a profundity and a taste which closely resemble those of a natural precious wood by delicately gradating a color tone in the transitive part of a veneer texture from a pale-colored wood to a deep-colored wood. SOLUTION: A colored adhesive is applied to the first surface to a material veneer using a double spreader, then a colorless adhesive is applied to the second surface and a laminated block obtained by alternately superposing pieces of the material veneer over each other and bonding them in a laminated fashion, is cut in a direction crossing the laminated face at an arbitrarily selected angle to obtain the veneer with a desired grain pattern. Thus a coloring agent contained in the colored adhesive applied to the first surface of the material veneer showing the pale color 7, penetrates from the first surfaced side of the veneer, and a color tone gradation 9 appears on the first surface of the veneer.  On the other hand, the colorless adhesive is applied to the second surface of the veneer and therefore, the penetration of the coloring agent contained in the adhesive from the lower side is inhibited. Consequently, no gradation is generation on the second surface of the veneer and the veneer with a grain pattern 8 closely resembling a natural precious wood is obtained.
