Title: Specimen recovering device
Inventor: NISHI SATOMI
IPC: H01L21/66
Filed: 1990-11-15
Abstract: PURPOSE:To remove impurities in a short time by bringing a suction nozzle into contact with a plate to be tested at the lowest point of the plate and recovering reaction solution. CONSTITUTION:A semiconductor substrate 11 is mounted on a stage 1, nitrogen gas is supplied from a bubbling nozzle 4a to a dilute hydrofluoric acid reservoir 4, and dilute hydrofluoric acid vapor is generated. Then a rocking rotation driving mechanism 8 is actuated to have the stage 1 rotated and rocked in a direction of an arrow. At the same time pure water and dilute hydrofluoric acid vapor is dripped on the substrate 11 by a pure water dripping nozzle 5 and a vapor nozzle 3, and the stage 1 is rocked and rotated for a predetermined time. Then after reaction between impurities on the substrate 11 and the dilute hydrofluoric acid is completed, the mechanism 8 is stopped. A suction nozzle 2 is moved from a B point to an A point and lowered to have reaction solution sucked. Then the nozzle 2 is moved from the A point to the B point, where suction pressure is released so that sucked reaction solution is dripped onto a recovering vessel 10. The reaction solution thus recovered is subjected to analysis of impurities in a subsequent process.

IPC: H05K1/02
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent the deviation of the printing position of cream solder by aligning each opening of a mask for printing cream solder with each unused land on a printed board one to one when each positioning guide member is inserted into each positioning hole. SOLUTION: The positional relation between each positioning guide member 14 and each positioning hole 22 is preset so that each opening 12 of the main body 11 of a metal mask 10 for printing cream solder may be aligned with each land 21 on a printed board 20 one to one. When electronic parts are mounted in a space between mounted parts for repairing, etc., the mask 10 is positioned by utilizing the positioning holes 22 provided around the lands in the space. Therefore, cream solder can be printed on the printed board 20 without positional deviation by means of a squeegee when the mask 10 is positioned by inserting the guide members 14 into the holes 22, because each opening 12 of the main body 11 is aligned with each land 21.

Title: Uneven code plate
Inventor: OTA HIROYUKI
IPC: H03M1/24
Filed: 1987-12-07
Abstract: PURPOSE:To eliminate the fear of utterly incoherent key input designation even when an operation is stopped in the intermediate position of each stage by setting the number of the times of the switching of each converting switch approximately equalized when bit movement is completed. CONSTITUTION:The four-bit constitution of an uneven pattern 13 of an uneven code plate 1 is not the arrangement conforming to a regular permutation from 0 to F(16), but the arrangement obtained by changing the permutation from 0 to F(16). That is, when the uneven pattern 13 moves the uneven code plate 1 in stages, only one switch out of four converting switches K1-K4 is switched to ON and OFF at every phased movement, and when the uneven code plate 1 completes the all operations of 16 stages, the uneven pattern 13 sets a sequence arrangement so that the number of the times of switching of the four converting switches K1-K4 may become approximately equalized. Thus, when the operation is stopped at the intermediate position of each stage color, the fear to designate the code of the unnatural stage can be solved.

Abstract: PURPOSE:To prevent overlap of an output clock signal by using an output signal outputted to a remotest load circuit among lots of load circuits connecting to a buffer circuit as a feedback signal so as to feedback it to a clock signal generating circuit. CONSTITUTION:NAND circuits 2c, 2d receive output clock signals CLK1, CLK2 received to remotest load circuits 4a, 5a among load circuits 4, 5 connecting respectively to buffer circuits 3a, 3b as feedback signals. Thus, even when a delay of the output clock signal CLK2 inputted to the load circuit 5a at the remotest position from the buffer circuit 3b is larger, after the CLK 2 inputted to the load circuit 5a transits to an L level, the CLK 1 of the buffer circuit 3a goes to an H level. Thus, output signals SG1, SG2 of the buffer circuits 3a, 3b are not overlapped. As a result, malfunction of the load circuits 4, 5 is prevented in advance.
