Title: Prevention of microbial corrosion
Inventor: YAO YASUKO
IPC: C23F15/00
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To effectively prevent corrosion of a metal material in an environment where microbes are present by allowing a reducing agent to be present in the environment so as to prevent or recover the environmental changes caused by the activity of the microbes in the environment. SOLUTION: The microbial corrosion of a metal material is affected not only by the activity of microbes but by the products produced by the microbial activity. It is supposed that corrosion of stainless steels in an underwater environment where microbes are present is caused by anodic polarization with abnormally enhanced corrosion potential to increase the local corrosion susceptibility. By the investigation of the influences of iron oxidizing bacteria frequently detected in the corroded part on the corrosion mechanism, it is found that a product functioning as an oxidizing agent due to the activity of microbes is produced on the material surface during the anodic polarization of the corrosion potential and this product affects the corrosion mechanism of the material.  Therefore, by adding a reducing agent such as L-ascorbic acid to the environment, corrosion of a metal material by microbes can be effectively inhibited.

Title: Regenerator of abrasive and regenerating method of abrasive
Inventor: TAGAMI AKIHIRO
IPC: B01D61/14
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To easily regenerate an abrasive containing abrasive grains having grinding performance equal to new liquid from an abrasive used for chemical and mechanical grinding by redispersing abrasive grains in the abrasive used for chemical and mechanical grinding. SOLUTION: Waste liquid of high concentration is delivered to a redispersing tank 45 from a dispersion medium pH adjusting tank through a high concentration waste liquid tank by a pump. At this time, the high concentration waste liquid passes the inside of an electromagnetic processing device 43 interposed in a high concentration waste liquid line 202. Bulky particulates in the high concentration waste liquid are redispersed by an ultrasonic wave of 10-30 kHz oscillated from an ultrasonic wave oscillating plate 46 in the redispersing tank 45. Additionally, a dispersant is input from a dispersant supply line 48 so that its concentration becomes about 0.1 wt.%-2 wt.% (for example, 0.5 wt.%) against the high concentration waste liquid.

Title: Isdn transmission processor
Inventor: NAKAMURA JUNJI
IPC: H04L12/70
Filed: 1991-05-21
Abstract: PURPOSE:To attain efficient communication by allowing an ISDN communication processor to insert a communication system supported by a opposite communication terminal into a cut message and inform the inserted message to a user. CONSTITUTION:When a call to an ISDN network 1 is unkown, a high layer matching information element in a call setting message is called without specifying a communication system. When a call from a opposite communication processor is cut off, the communication system inserted into a cut message is analyzed by a communication system control part 3 and an analyzed result is displayed on a display part 6. When there is an incoming call from the ISDN network 1, if there is the specification of communication system to the high layer matching information element of the call setting message by the communication system control part 3, the incoming call processing is performed. When there is no specification of a communication system, all communication systems supported by the communication processor of the self-system are inserted into the cut message to cut off the call. Thus communication can be executed without applying load to the user.

IPC: F16L37/08
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To confirm the completely connected state of a pipe body by sound by inserting the metal pipe body in an inner collar of a female body, then pressing a pressing member such as a hard ball to the joint deep part side along with the inner collar when the tip of the pipe body presses the pressing member, and generating sound when the pressing member falls into a peripheral groove. SOLUTION: When a pipe body 40 is inserted in an inner collar 8 into a position where the tip 41 of the pipe body 40 collides with a step part 2, a pressing member (ball) 9 is fitted into a peripheral groove 42 formed at the outer peripheral surface of the pipe body 40, and the ball 9 falls into the peripheral groove 42 to generate sound. In the completely connected state of the pipe body, in case of pull-out direction force acting upon the pipe body, the ball 9 is pressed to the taper part 11 side of an outer collar 10 by a spring 7, and the ball 9 is pressed to the surface of the pipe body 40 by the taper part 11 so as to impede pull-out of the pipe body 40. In case of detaching the pipe body 40, the outer edge part of the inner collar 8 is pressed by a tool or the like to move the inner collar 8 to the female body 1 side, thus releasing fastening force of the ball 9.

Title: Production of transparent alumina
Inventor: HAYAKAWA JUNJI
IPC: C04B35/115
Filed: 1990-05-08
Abstract: PURPOSE:To produce transparent alumina by successively concentrating light to a bar-shaped alumina sintered body mixed with a light absorbent only at the front end from the front end, thereby melting the front end. CONSTITUTION:For example, a slurry prepd. by mixing the alumina having 0.6mu average grain size and 99.8% purity and cobalt oxide of 1wt.% of this alumina, water, and binder is poured into a gypsum mold (half split molds) matching with the alumina sintered body. The slurry prepd. by mixing the same alumina, water and binder as mentioned above is then poured into the mold to obtain the green alumina molding having the cobalt oxide existing only at the front end. The molding is calcined for 2 hours at 1200 deg.C to obtain the alumina sintered body 1. The sintered body is installed in a bielliptic heating furnace and while the sintered body 1 is rotated, the sintered body is begun to be heated from the lower part added with the cobalt oxide and the focus of the light is moved upward at 5cm/hour speed. Consequently, the transparent part 1' consisting of the alumina alone solidified after melting is obtd.

Title: Semiconductor superlattice crystal
Inventor: FUKUI TAKASHI
IPC: H01L29/778
Filed: 1980-08-26
Abstract: PURPOSE:To improve mobility, and to obtain an element functioning at superhigh speed by alternately laminating InAsSbP, a lattice constant thereof agrees with that of an InAs substrate and which has a predetermined composition, on the substrate in fixed thickness. CONSTITUTION:InAs with d1 thickness and InAsxSbyP1-x-y (x=1-3.2y), thickness thereof is d2 and the lattice constant thereof is equal to InAs, are alternately laminated on the InAs substrate, and d1 and d2 shall be approximately 10-300Angstrom . In this case, electrons are confined in the InAs layers in case of an N type semiconductor. When normal InAs, the mobility of electrons is limited by the concentration of impurities in a low temperature region (approximately 100 deg.K), and when the concentration of electrons becomes high (10<17>cm<-3> or higher) the mobility slows down because the concentration of a corresponding donar also increases. When N type impurities of N>=10<18> are added and laminated to the InAsSbP, the electrons of the InAsSbP ooze to the InAs with low potential. Accordingly, the concentration of electrons becomes high even when the concentration of the donar of the InAs is low, and the mobility increases.
