Title: Electronic black board
Inventor: OGASAWARA TSUTOMU
IPC: H04N1/00
Filed: 1991-12-09
Abstract: PURPOSE:To prevent the deterioration of a quality due to a noise by deciding the position of a conveying roller so that a reading position can be irradiated not with a reflected light from a folded part, but with only a direct light from a light source. CONSTITUTION:A driven roller 4 is arranged apart from a reading position 7 in a prescribed amounts. The prescribed amounts are set so that light quantity when the folded part by the driven roller 4 is irradiated with the direct light from a light source 8, and a reading line at a reading part 7 is irradiated with the reflected light can be extremely smaller than the light quantity when the reading line is directly irradiated with the light from the light source 8. Thus, the reading position 7 can be irradiated with only the direct light from the light source 8, so that a reading quality can not be affected by the state of a sheet face.

Title: Structure for tail section of shield machine
Inventor: MORITA TAIJI
IPC: E21D11/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of negative pressure and surely conduct the back-filling material filling work by applying a downward grade from the natural ground side toward the segment side on the tail plate end edge of the tail section of a shield machine. SOLUTION: A downward grade from the natural ground G side toward a segment 4 is applied to the end edge of a tail plate 7, and a tail seal 8 is fitted at the position approaching the working face side by some size at the end edge lower section of the tail plate 7. The outside face of the tail plate 7 is closely stuck to the natural ground side, and the inside face of the tail plate 7 is closely stuck to the segment 4. A grout hose 10 is connected to a grout hole 9 provided on the segment 4, and a back-filling material 6 is filled. When a shield machine is advanced forward after the back-filling material 6 starts to be hardened, the back-filling material is completely peeled without causing negative pressure because the end edge of the tail plate 7 has the downward grade from the natural ground G side toward the segment 4.  The back- filling material 6 can be surely filled in a tail clearance 5 without generating a rupture face on the back-filling material 6.

Title: Gas burner
Inventor: TOMIURA HIDEYUKI
IPC: F23D14/06
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To prevent a flame from remaining in a distribution chamber when firing is again done after fire extinguishment operation by mounting a rectifier plate on a corner part located between an upper wall plate and an outer peripheral wall plate of the distribution chamber, and preventing mixed air flowing into a mixing chamber from remaining at the corner part. SOLUTION: A rectifier plate 5 is mounted on a corner part 6 formed between an upper wall plate 30a of a distribution chamber 30 and a placement part 32 of an outer peripheral wall plate 30b, located on a one peripheral side of the distribution chamber 30 for preventing mixed air flowing in from a mixture pipe 2 from staying at the corner part 6. Hereby, the corner 6 is closed with a slope 51 of the rectifier plate 5, and the mixed air flowing from the mixture pipe 2 becomes a spiral flow and is guided to the slope 51 of the rectifier and is driven to smoothly flow to each window hole 31 without staying there.  Accordingly, even if the flame is extended back up to the position of the corner 6, the flame is prevented from entering the corner 6 owing to the rectifier plate 5, and when the mixed air is supplied with a refiring operation, the flame is pushed back with the mixed air and combustion in the burner body 1 is prevented from being continued.

Title: Transaction processing system
Inventor: INOUE TOSHIYUKI
IPC: G06F19/00
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To avoid the occurrence of distributed deadlocks between plural resources. SOLUTION: A delay updating management processing 43 declares 43a transaction start to a data base management system and shifts to non-processed message read 43b. In the processing 43b, a message table 49 inside a sender side data base 45 is accessed and a message whose completion flag is 'incomplete' is retrieved and read as a non-processed message. In the processing of message transmission to a pertinent destination and result reception 43c, the read non- processed message is transmitted to the side of a processor F corresponding to the destination and a service name along with a 'transmission origin' and a 'message ID'. The transmission of a processing result in transfer money reception 51 is received.  In updating 43d for turning the completion flag to 'completed', the processing result in the transfer money reception 51 to the message received in the processing 43c is written to the 'completion flag' of the message table 49. Only when the processing is correctly performed, the 'incomplete' is changed to 'completion'. When the processing 43d is ended, transaction completion is declared 4e to the data base management system.

Title: Manufacture of inner wiring preventing corrosion of plug
Inventor: SAI NENYU
IPC: H01L21/28
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent corrosion of an exposed metal plug and to improve performance of a device by forming a protective film on the surface of a metal plug which is exposed because of thermal oxidation or the like after ashing photoresist by oxygen plasma and before wet cleaning. SOLUTION: In a method for preventing loss of a metal plug 206, after eliminating photoresist 218, a protective film 222, for example an oxide film is formed on the exposed metal plug 206 for preventing electrical charge from being collected on it. Then a substrate 200 is subject to wet cleaning. Since the exposed metal plug 206 is covered with the protective film 222, contact between the metal plug 206 and an alkaline solution can be avoided by the protective film 22 even if electrical charge is collected on the surface of the metal plug 206 in an atmosphere of oxygen plasma. In this way, contact resistance can be made correct, the device performance can be improved and the yields can be also improved.

Title: Measuring apparatus for nuclear reactor output distribution
Inventor: ODA MINORU
IPC: G21C17/10
Filed: 1987-12-25
Abstract: PURPOSE:To facilitate the application for a newly opened plant as well as an existing nuclear reactor with an easier calibration, by using a Fourier coefficients calculating means and a conversion means to obtain a data for initial calibration. CONSTITUTION:A Fourier coefficients calculating means is used for NPj and NDk obtained with the normalization of a section integral value Pj of a reactor output distribution P(Z) and an detector output Dk to apply a Fourier coefficients transform matrix [Q]<-1> and a Fourier coefficient CPi of a reactor output section integral value and as a Fourier coefficient CDi of a neutron detector output are derived from the results. The coefficient CPi is determined from the coefficient CDi by a formula using a diagonal matrix [Aij] and a correction vector [Bi] as conversion means. An initial calibration is performed in such a manner that the diagonal matrix [Aij] and the correction vector [Bi] are determined by least square from numerous combinations of reactor output section integral value Pj measured and neutron detector outputs Dk as measured. This allows the relaxation of a required number of data necessary for initial calibration and demand for versatility, thereby facilitating the initial calibration.
