Title: Prime arranging fillet cap construction method
Inventor: TAGUCHI YOSHIMITSU
IPC: F16L55/10
Filed: 1994-06-27
Abstract: PURPOSE:To prevent take fire to gas in a gas flow pipe at welding time without executing a nitrogen gas injecting process, by performing welding a fillet cap against a cut end part of the gas flow pipe in a condition that inside the gas flow pipe is exhausted further to seal an outflow of gas in the gas flow pipe by a heat resistant seal member. CONSTITUTION:In the case of fixedly welding a fillet cap 4 in the cut end part periphery of a steel pipe-made main pipe 1, a diffusion pipe 2 is connected to the main pipe 1, to insert a rubber ball 3 (3a, 3b) into the main pipe 1 from this diffusion pipe 2. In a condition that each rubber ball 3 is inflated to temporarily close the main pipe 1, a heat resistant seal member 11 is interposed between itself and a cut end face 1d, to fit a fillet cap 4 to the cut end part periphery. Next by using screw bars 8... and nuts 9... equally arranged in a circumferential direction relating to a fixe band 7 fixed to the cut end part periphery, the cap 4 is uniformly pressed to the cut end face 1d by a pressing plate 10. Thereafter, the temporarily closed condition by the rubber ball 3 is released to exhaust air in the pipe, and the cap 4 is welded to the main pipe 1.

Title: Rotary head device
Inventor: TAKEBAYASHI TAKASHI
IPC: G11B5/53
Filed: 1989-06-06
Abstract: PURPOSE:To remarkably simplify assembling work leaving a magnetic head at a conventional position by directly sticking and fixing the magnetic head on one side at a rotary drum, and adjusting the position of the magnetic head on the other side with a conventional method setting the above magnetic head as reference. CONSTITUTION:The magnetic head 15a on one side out of a pair of magnetic heads 15a and 15b is directly stuck and fixed at the sticking part 24 of the rotary drum 17. Also, the magnetic head 15b on the other side is comprised so as to fix its head base 12 at the rotary drum 17 with a screw as in a conventional device, and at this time, the positioning adjustment in the circumferential, radial, and height directions of the rotary drum 17 of the magnetic head 15b are performed by using conventional jig tool and adjusting screw setting the position of the magnetic head 15a as reference. Therefore no adjusting process in the circumferential, radial, and axial directions using the conventional jig tool and adjusting screw is required for the magnetic head 15a on one side. Also, since the conventional jig tool and adjusting screw can be used as it is when the position adjustment of the magnetic head 15b on the other side is performed, no additional facility is required.

Title: Manufacture of semiconductor integrated circuit device
Inventor: TANEOKA TADAYUKI
IPC: H01L29/732
Filed: 1987-06-12
Abstract: PURPOSE:To form very narrow grooves with good reproducibility, by forming edges on both sides of the groove by only a selective etching method in which an impurity concentration difference is used. CONSTITUTION:After an insulation film 10 is removed by etching, an alkaline etching solution of hydrazine, for example, is used to perform selective etching of a polycrystalline silicon film 9 and to form a groove 12. A ratio of etching rates, that is, a selection ratio, between polycrystal silicon doped with boron and that undoped with boron is made very large, for example, in degree of 500. Accordingly both edges of the groove 12 can be hence formed exactly at a boundary position between the part doped with boron and that undoped with boron. Namely the groove 12 can be formed by only a selective etching method in which an impurity concentration difference is used. Very narrow grooves can be hence formed with good reproducibility.

Title: Direct drawing type planographic printing base plate
Inventor: KATO EIICHI
IPC: B41N1/14
Filed: 1990-06-06
Abstract: PURPOSE:To enhance the adhesiveness of an image part to oily ink, to hold the hydrophilicity of a non-image part and to obtain high printing durability by preventing the generation of oil contamination by adding a specific resin and, if necessary, a crosslinking agent to the binder of an image receiving layer. CONSTITUTION:The binder of the image receiving layer provided to a support contains a resin [A] having at least one kind of a formyl group or a functional group represented by formula (I) and a thermosetting and/or photo-setting resin [B] and further contains a crosslinking agent if necessary. When the image receiving layer is treated with a treatment solution containing a hydrophilic compound having nucleophilic reactivity, a hydrophylic substance having nucleophilic reactivity is added to and reacted with the terminal of the formyl group of the resin [A] or the terminal of the formyl group formed from the functional group represented by the formula (I) by acid decomposition and, therefore, the image receiving layer can develop hydrophylicity and becomes insoluble or hardly soluble to water while holding hydrophilicity because a crosslinked structure is present in the binder resin. By this method, a copy image faithful to the original picture can be reproduced and, since the hydrophilicity of a non-image part is well, no background staining is generated.
