Title: Preparation of shadow mask
Inventor: OKUDO YUKIO
IPC: C23F1/46
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a preparation method of a shadow mask while easily adjusting a proper etching liquid and prolonging a service life of the etching liquid to reduce the waste. SOLUTION: The shadow mask is prepared by spraying an etching liquid containing ferric chloride as a principal component to the surface of a thin metallic plate 20 where resists 23a, 23b having patterns corresponding to openings 24 of the shadow mask are formed to form the openings on the shadow mask by etching and recovering the sprayed etching liquid to be reused. In this case, the concentration of the etching liquid when it is stored or transported is made lower than that of the etching liquid when it is used for etching and a relatively higher concentration etching liquid is fittingly added to the etching liquid to be used for etching. The relatively higher concentration etching liquid is prepared by adding iron and chlorine to the relatively lower concentration etching liquid to chemically react with each other.

Title: Balancing device
Inventor: GOTO KANAME
IPC: B23Q1/25
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To cancel twist acting on a horizontal shaft of machine tool and a table device.

Title: Ion inplantation device
Inventor: FUJIKURA YOICHI
IPC: H01L21/265
Filed: 1986-05-19
Abstract: PURPOSE:To enable precise inplantation control by comparing the computed speed characteristic with the speed characteristic at the time of implantation made by simulated current, and correcting the speed characteristic at the time of inplantation on a real sample. CONSTITUTION:In a mechanical scanning process, scanning speed V of a sample mounting rotary disk 5 is regulated to a value represented by the formula to remain uniform. (K is a constant, I is inplantation ion current and R is the distance from the rotary disk center to ion beam irradiation position.) Concurrently with the mechanical scanning, a scanning position sensor 10 sends position data R to a scanning speed calculator 17 which computes the scanning speed V every time the position data R changes and sends a speed command to a power source. With the value of R determined by the size of a sample 12 and speed characteristic computed by the scanning speed caluculator 17 in advance assuming that I is a constant current independent of time, inplantation time can also be computed. Then a switch 15 is set to (b) side and inplantation is performed with the same current as I. If the calculated speed V and speed V' during inplantation with the simulated current are different, from each other, the scanning speed calculator 17 makes a correction for it.

Title: Method for collecting state change data
Inventor: TOKITO KIYOSHI
IPC: H04Q9/00
Filed: 1988-05-11
Abstract: PURPOSE:To eliminate the difference in time for collecting state change data due to the unevenness of the assigned level of a child station number and to collect the state change data in a short time all the time by giving each child station a function to send a state change occurrence signal so that respective state change occurrence signals sent from respective child stations can be different with each other. CONSTITUTION:When the state change occurs in a child station 2n while a child station 21 makes a response, a transmitting circuit 6n is started up, and the state change occurrence signal is sent to a parent station 1. When the station 1 receives the state change occurrence signal by a receiving circuit 5, the parent station 1 identifies the occurrence of the state change in the child station 2n, waits for the completion of the reception of a response signal from the child station 21, composes a state change polling signal with a child station number 2n as its destination, and sends the state change polling signal to the child station 2n. In the child station 2n, after a received calling is detected by a logical circuit 7n, the state change data are sent to the parent station 1 as the response signal. In the parent station 1, the completion of the reception of the state change data response signal is detected, and the polling signal for the next station is sent. Thus, the state change data can be collected without long waiting time for the occurrence of the state change in any child station.

Abstract: PURPOSE:To obtain good electrostatic chargeability by forming an SiN:P:H film as a blocking layer using disilane with N and P added to it, to a photosensitive body having a photoconductive layer made of a-Si:N. CONSTITUTION:A thermally and structurally stabilized amorphous silicon nitride film (a-SiN:H) is formed as the photoconductive layer on a conductive substrate to form a photosensitive body, and further, a film (a-SiN:P:H) is formed as a blocking layer at the time of negtive charging in a thickness of 1-10mum on the conductive substrate by using disilane (Si2H6) as a main source gas and adding N2 and P at the same time. The a-SiN:P:H film thus formed has superior n type characteristics, and Fermi level is moved sensibly, and the use of this film for the blocking layer on the side of the substrate can prevent injection of holes from the substrate side, and permits the film thickness of the photoconductive layer to be enlarged, and the photosensitive body superior in electric and optic characteristics to be obtained.

Title: Spectrochemical analysis of radioactive liquid
Inventor: MATSUI TETSUYA
IPC: G01N21/64
Filed: 1989-05-08
Abstract: PURPOSE:To prevent the radiation damage of optical fibers, to recover the fibers therefrom and to stably use the fibers over a long period of time by simultaneously subjecting two pieces of optical fibers; an optical fiber for transmitting exciting light and an optical fiber for transmitting fluorescence to photobleaching by irradiation of a laser beam. CONSTITUTION:The laser beam of a 1st layer 1 is divided to the optical fiber 11 side for transmitting exciting light and a power monitor 7 side by a beam splitter 5. The laser beam passing the inside of the fiber 11 prevents the radiation damages of the fiber 11 by a photobleaching effect to recover the fiber from the damage and is made incident to an optical cell 14 to excite a sample. The excited sample radiates fluorescence which is then transmitted by the optical fiber 12 for transmitting fluorescence and is detected by a photodetector 10. On the other hand, the laser beam of a 2nd laser 2 passes a half mirror 6 and is entered into the fiber 12 to prevent the radiation damages of the fiber 12 by the photobleaching effect so as to recover the fiber from the damage. The long-term stable use of the optical fibers is possible in this way by simultaneously subjecting the two fibers to the photobleaching.
