Title: Sheet double feed detecting device
Inventor: TAKEU YASUHIRO
IPC: B65H7/12
Filed: 1988-05-24
Abstract: PURPOSE:To perform accurate detection, by a method wherein a difference between outputs from a reflection type sensor mounted in a position on a sheet conveyance passage through which a plurality of sheets are conveyed in succession is detected, and when the difference exceeds a given value, it is decided that a double feed occurs. CONSTITUTION:Sheets from a cassette 13A of a feed part 10 are fed continuously and one by one by means of a feed roller 13B. The sheet delivered to a sheet conveyance passage 14 by means of a conveyance roller 15 of a sheet conveying part 11 is moved on a running member 19 having a low reflection factor and conveyed to a roller part 16. A reflection type photo sensor part 18 is disposed above the running member 19, the sheet is irradiated with light, a reflection light from the sheet is detected, and a detecting result is inputted to a detection processing part 12. The running timing of the sheet is detected by a sensor 17 located on the downstream side of the roller part 16 to input it to a detection processing part. When a difference between the levels of reflection lights from an N-th sheet and (N+1)-th sheet exceeds a preset value, it is decided that a double feed occurs to the N-th sheet or the (N+1)-th sheet. This constitution prevents the occurrence of a malfunction due to lowering of the sensitivity of an optical system, and causes accurate detection of a double feed.

Title: Welding method for steel coating high melting point metal
Inventor: MATSUMOTO KEIICHI
IPC: B23K9/23
Filed: 1986-05-30
Abstract: PURPOSE:To prevent the deformation of a high melting point metal the deterioration in corrosion resistance and the crack by widening the gap of the welding groove of the title material, welding a high melting point steel at the beginning and welding the steel part with cooling the weld zone of high melting point with a coolant thereafter. CONSTITUTION:The distance T of the groove 3 in welding of the title steel 1 is made wider than usual. The welding of a high melting point metal 2 is first performed with the ordinary method and then the insertion plate 5 executing the beveling for welding having the same material as that of the steel is inputted. After installation of the insertion plate the welding of the 1st layer 7 of the steel is performed with flowing or blowing a coolant 8 to the inner side of the high melting point metal 2. The welding of the 2nd layer and on is performed in order thereafter. As a result there is no melting on the welding peripheral part of the high melting point steel nor heat deformation even in case of the thickness of this metal being thin. There is no immersion of an iron, carbon, etc. into the high melting point metal side while under welding of the steel, nor spoiling the corrosion resistance and mechanical property.

Title: Oil leakage preventing apparatus for bearing
Inventor: OONISHI AKIRA
IPC: F16C33/74
Filed: 1981-08-14
Abstract: PURPOSE:To minimize the reduction of lubricating oil and to prevent environmental pollution, by providing a pre-filter and a clean air intake section between an exhaust pipe and an oil recovering means. CONSTITUTION:A pre-filtering section 18 and a clean air intake section 19 are provided between an exhaust pipe 11 and an oil recovering means 15 so as to supply clean air 20 into the exhaust pipe 11 and to thereby make up for the difference between the amount of air drawn out from an outlet section 13 and the amount of air supplied from an intake pipe 9 plus the amount of oil mist 7 produced in an oil tank 5. Resultantly, the amount of air drawn out from the section 13 can be made substantially equal to that of air forced into the section 13. By employing such an arrangement, oil mist 7 produced in the tank 5 is not forcedly drawn into the exhaust pipe 11, so that reduction in the amount of lubricating oil 6 in the oil tank 5 can be minimized. Further, since oil and air in the oil mist 7 are processed more efficiently in a separated manner as compared with the conventional arrangements, the amount of oil contained in air 20a exhausted to the outside of the apparatus can be reduced, so that environmental pollution by oil can be minimized.

Title: Instrumented nozzle
Inventor: HAYASHI MAKOTO
IPC: B23K9/00
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent a fretting fatigue failure by providing a difference in level on the mounting welding part of a nozzle so as to have a diameter larger than the nozzle tip, and connecting this diameter increased part of the nozzle to a stub provided on a piping by welding. SOLUTION: A nozzle 13 has a difference in level to increase the diameter on the base side. The inside diameter of a stub 12 is increased according to tit, and the nozzle 13 is inserted thereto and connected in a mounting welding part 15'. When the upper end of the stub 12 is conformed to the corner part of the difference in level part of the nozzle 13 followed by welding, fretting fatigue is not caused since the outer surface of the nozzle 13 does not contact the inner surface of the stub 12 or the welding metal. Only the stress collection resulted from the reverse corrugated form of the welding part 15' can be considered. Thus, the failure by fretting fatigue resulted from the flowing vibration of the nozzle 13 can be prevented.
