Abstract: PURPOSE:To improve mechanical property and stress distribution against fatigue through eliminating stress concentration in the vicinity of a under head portion by forming a straight pipe portion having an enlarged diameter in the vicinity of the under head portion of a connecting head portion, a tapered wall portion whose diameter decreases from the straight pipe portion gradually, and, in addition, by press fitting a washer member on the enlarged diameter straight pipe portion so that compression stress may remain in the enlarged diameter straight pipe portion. CONSTITUTION:At an end portion of a thick wall small diameter metal pipe 1, a trapezoidal cone-shaped connecting head portion 2, whose external peripheral surface toward the connecting direction is a pressing seat surface 2' to be brought into contact with a seat of a mated injection nozzle, a straight pipe portion 3, whose diameter is enlarged slightly in the vicinity of the under head portion of the head portion, and a backward tapered wall 4 connected to the straight pipe portion 3 are formed. Then, a washer member 5 is located by press fitting at the straight pipe portion 3. Next, a tightening nut 6 is brought into contact with a rear end peripheral surface of the washer member 5 and is connected to a mated part by tightening the screw. As the result, it is possible to reduce and prevent crack and fracture greatly, and to keep stable connection and useful life for a long time.

Title: Manufacture of semiconductor device
Inventor: ARIMOTO YOSHIHIRO
IPC: H01L27/12
Filed: 1986-12-16
Abstract: PURPOSE:To obtain an SOI substrate having excellent adhesiveness, by a method wherein a pulse type voltage, whose polarity is alternately changed, is applied several times across two Si substrates at a temperature lower than or equal to a maximum heating temperature when an SOI substrate in which junction is made by siloxane bond of SiO2. CONSTITUTION:On Si substrates 10 and 10' formed are SiO2 films 11 and 11' which are brought into close contact with each other; then, the work is put in N2 gas. The Si substrates 10 and 10' are heated and, at a temperature of 400-800 deg.C, a DC voltage of 50-200V, whose polarity is alternatly changed at 10-10<3> msec intervals, is applied several times from a bonding power source 32. Then the substrats are heated at 900-1000 deg.C. In the case where the voltage whose polarity is changed in the form of a pulse is applied, the dielectric breakdown of the SiO2 film is prevented, and the voltage drop due to non-ohmic contact of the connection part between the substrate and a lead wire can be prevented. Further the internal stress of the substrate is decreased and so damage is reduced. On heating, Si-OH radical is subjected to dehydration condensation, and siloxane (Si-O-Si) radical is generated. Electrostatic pressure caused by applying the voltage acts upon the contact part of SiO2, so that boding is more strengthen. By the effect of applying pulses, the Si substrate can maintain high quality, and by eliminating the substrate of one side, an SOI substrate of high quality can be obtained.

Title: Network controller
Inventor: UYAMA HIROTO
IPC: H04M11/00
Filed: 1989-11-21
Abstract: PURPOSE:To reduce the signal loss by turning off an operating switch when a polarity inverting signal reaches a 2nd prescribed voltage or over or a release signal is outputted from a terminal equipment and turning off a connection switch. CONSTITUTION:An operating switch 94 is operated in response to a polarity inversion signal and the polarity inversion signal fed via the operation switch 94 reaches a 1st prescribed voltage or over, then the connection switch 81 is operated and while the switch 94 is in operation, the connection switch 81 keeps operation to connect a telephone line to a terminal equipment 5. When the polarity inversion signal is a 2nd prescribed voltage or over or a release signal is outputted from the terminal equipment, the operating switch 91 is turned off and the connection switch 81 is turned off, Thus, the signal loss is reduced with simple circuit constitution and a high DC resistance is realized in the off-state.

Title: Recording medium recorded with installation auxiliary program, and storage medium recorded with uninstallation program
Inventor: URA YOSHIKI
IPC: G06F13/10
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a storage medium recording an un-installation program which can return a storage medium recording an installation auxiliary program with which an installation processing by OS is not interrupted and an information processor main body to a state before installation by copying a file required for installation in the processor body before a peripheral unit is installed in the information processor of a personal computer operating by specified OS.

Whole driver data bases are deleted (n3). Since the file required for installation is copied in PC before the execution of an installation processing, the file is not retrieved against FD in the installation processing. Namely, the file which is not required for installation is not requested to a user. Thus, the installation processing is not interrupted.

IPC: C08F8/28
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain a water purifier which, when used for a closed water system, purifies the water in the system with persistence of the purifying effect by using a specified polyvinyl alcohol hydrogel. SOLUTION: This water purifier for a closed water system comprises a polyvinyl alcohol hydrogel having a water content of 50-99wt.% and a degree of acetalation of 10-50mol%. It is desirable that the hydrogel has a network structure inside with a mean pore diameter (in terms of circle diameter) of 0.5-20μm. Such a network structure is obtained by freezing an aqueous polyvinyl alcohol solution, preferably having a concentration of 1-40wt.%, at a temperature of -5 deg.C or lower. The acetalation is effected preferably after thawing. A water- soluble high-molecular polysaccharide may be added for forming the gel into an arbitrary shape. A microorganism may be incorporated into the aqueous polyvinyl alcohol solution, but it is better to deposit the microorganism on the gel after forming the gel.
