Title: Water quality measuring device
Inventor: URUSHIBARA SHOTARO
IPC: G01N33/18
Filed: 1989-06-15
Abstract: PURPOSE:To effectively prevent the adhesion of a contaminant to a measuring device and to remove string-like dirt by engaging the lower end of the blade of a detection part with the step part of a wave preventing pipe. CONSTITUTION:The detection part 1 of a measuring device consists of a side surface detection type DO electrode 11, a body part 12 and a blade part consisting of three blades 13. The inner diameter of a wave preventing pipe 2 is formed into a stepwise state so that the lower parts of the blades 13 are engaged with a step part 25. Therefore, the detection part 1 is accurately set at a predetermined position only by allowing the measuring device to fall in the wave preventing pipe and, when the detection part 1 is moved upwardly from the set position, gaps are formed between the wave preventing pipe 2 and the blades 13. Since the lower ends of the blades 13 are inclined so as to be capable of guiding dirt in the outer end direction thereof, the dirt hooked with the blades 13 are gathered to the outer end parts of the lower ends of the blades 13 and easily flows out of the gaps formed by the upward movement of the detection part 1. Since the interval between the DO electrode 11 and the wave preventing pipe 2 is narrowed, washing effect due to air bubbles can be enhanced.

Title: Method of cleaning silicon wafer
Inventor: IWAMOTO YOSHIO
IPC: H01L21/304
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To provide a method of cleaning a silicon wafer in which small foreign matters which cause a device defect are prevented from being enlarged in such a manner that a silicon wafer is polished and roughly cleaned and acid cleaning is performed before chemical vapor deposition. SOLUTION: A silicon wafer 1 is roughly cleaned mainly with a cleaning solution (APM solution) obtained by diluting ammonia hydrogen peroxide with ultrapure water and is polished and silicon dusts and the like are removed. After that, acid cleaning is performed and large pieces of salt are formed by ammonia having excellent hygroscopicity in the APM solution to saturate alkali substances, thus preventing growth of small foreign matters 3 remained on the silicon wafer 1 even after the cleaning with the APM solution. Also, a film 5 is masked to prevent occurrence of projections. Thus, the growth of the small foreign matters 7 causing occurrence of a device defect is prevented during a CVD (chemical vapor deposition) process.

Title: Oil supplier for automatic tool replacing device
Inventor: HOSOI TOSHIAKI
IPC: B23Q11/10
Filed: 1985-07-11
Abstract: PURPOSE:To perform tool replacement quickly by furnishing a nozzle at the tip of a drover, making a cooling oil path in the nozzle in such a dimension that the cooling oil does not drop due to capillary phenomena, and thereby preventing spattering of the cooling oil of tool replacement. CONSTITUTION:A drover 2 is sunk so that a detent part 22 is located in the major dia. portion 93, and balls 8 retract outwards to release retaining force of a pull stud 4, and then a tool holder 3 is sunk for removal. In this condition, the cooling oil path 6 in nozzle 5 has residual oil, but the section area of the path 6 has such a dimension as capable of holding the cooling oil with capillary phenomena, so that the cooling oil will not drop even after the tool holder 3 is removed, to ensure that inside a spindle 1 is free of contamination. Even though the cooling oil has eventually dropped off from the tip of the nozzle 6, this construction with extension till the inner bottom of the spindle 1 ensures that the oil drops to outside of the spindle 1. Thus the inside will never be contaminated.

Title: Morse code receiver
Inventor: MISE MASAKAZU
IPC: H04L15/24
Filed: 1978-12-09
Abstract: PURPOSE:To realize an automatic reception circuit for Morse codes which can absorb the difference of the keying actions of the operator by checking the length of the Morse codes. CONSTITUTION:The circuit makes use of the 3:1 ratio between the long and short codes. With reception of code.--., length of the 1st short spot is shown in the value obtained through calculation by counter R1 to be compared with latest short spot count value R3 at comparators MC1 and MC2. The comparator gives the decision between the long the short spots via the duration ratio between the short and long spots. Then with detection of sigmal 0 among the codes, the short spot value of counter R1 is supplied to counter R2. And with reception of the next long spot, a comparison is given at comparator MC3 for the value between counters R1 and R2 for the decision of the long spot. The combinations between the short and long codes thus obtained are decoded to be delivered through the ROM in the form of the character code. In this instant, counter R4 counts the length of code 0 to detect the distance between the characters in comparison with the value of counter R3.

Then, during rotating the rollers 31, 31 at 360 deg., the force reciprocatively swung from right to left in vertical plane containing the axial center is acted to the tube body 8. On the other hand, during rotating the upper rollers 33, 34, which the axial direction is crossed at the right angle to the lower step rollers, the tube body 8 is reciprocatively swung from right to left as the same way as the lower step rollers. Therefore, the swinging forces with the rollers at the upper and lower steps are composed and the gap between the mold hole 11 and the pipe body 8 is uniformized, to obtain the tube body 8 without any uneven thickness.

IPC: A61B17/06
Filed: 1987-06-22
Abstract: PURPOSE:To prevent the breakage of a welded part or bending at an acute angle due to a crack, by softening the periphery of the welded part of a pipe and a needle both of which are made of stainless steel to bring the same to a state near to the hardness of the welded part. CONSTITUTION:A needle main body 1 and a pipe 2, both of which are made of 18-8 stainless steel having no quench hardenability such as SUS 302 or SUS 304, are welded at a welded part 3 by laser beam to constitute an eyeless suture needle. A burner 8 such as a propane gas burner is used and the periphery of the welded part 3 of the suture needle and the almost whole of the pipe 2 are heated to about 1,000 deg.C by the flame of the burner 8 and softened. As a result, the periphery of the welded part 3 and the whole of the pipe 2 can be constituted softly so as to have hardness of about 200-280. By this method, it can be perfectly prevented that a crack is generated in the welded part of the suture needle to generate breakage or bending at an acute angle, even when bending stress is applied to the suture needle at the time of use. Further, caulking for mounting a suture is made easy.

And No.3 and No.4 spokes, and No.3 and No.4 holding rings 33 and 34 are replaced in a similar manner. Subsequently, both the lifting frame 3 and the spoke suspen sion 44 are restored to the original position, then the holding rings 31 and 34 are relatively rotated again by the specified angle. This configuration enables works involved to be accomplished by one single process.
