Title: Method and system for detecting and correcting erroneous irradiation taking place in x-ray image pickup for patient
Inventor: ARAGONES JAMES KENNETH
IPC: A61B6/00
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for detecting or correcting erroneous irradiation taking place in X-ray image pickup with which picture quality can be improved. SOLUTION: X-ray image pickup setting for picking up the image of a patient 14 is selected. The values showing the quality of X-ray beams and the dose of X-rays are generated from the selected X-ray image pickup setting. The ratio of irradiation is predicted from the values showing the quality of X-ray beams and the dose of X-rays. Next, the patient 14 is irradiated with the X-ray beams having the values showing the quality of generated X-ray beams and the dose of X-rays. The ratio of all the irradiation is determined and compared with the predicted ratio of irradiation. This comparison is used for judging whether the patient is irradiated at an erroneous level or not. When the irradiation is performed at an exact level, the irradiation is finished later.  When the irradiation is not performed at the exact level, the irradiation is stopped later and controlled to a new irradiation level.

Title: Formation of electrode and wiring layer of semiconductor device
Inventor: SUZUKI TOSHIKI
IPC: H01L21/302
Filed: 1978-10-16
Abstract: PURPOSE: To obtain an Al electrode wiring layer with a fine pattern by getting a thin W protective layer adhered to the surface of the Al electrode wiring layer; covering regions other than those specified with photosensitive resin; and removing only the W layer and the Al layer under the resin after plasma-etching.  
     CONSTITUTION: Making a SiO 2  layer 2 grow on Si substrate 1 where an active region 4 has been formed and boring a hole through the region 4, an Al layer 3 is made to stick to the surface including the opening, using the sputtering method. Next the Al layer is covered with a thin protective W layer 5 through the sputtering method, than a pattern 6 composed of photosensitive resin is formed on the layer excluding the opening. Thenceforward, the wafer is treated in a gas plasme etching apparatus so as to remove the layers 5 and 3 under the pattern 6, then the layer 5 out of the remaining layers 5 and 3. The remaining layer 3 is made into an Al electrode wiring layer 3. It is due to reducing substances such as CO produced during decomposition that only the layers under the pattern are removed. The exposed layer 5 is not etched, and the reason for this is that there is WO 3  which has an extremely high melting point.

IPC: H05B41/24
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent over-voltage using a low-cost circuit configuration in which power zenor diode is no more used. SOLUTION: In case the impression voltage on control circuits 9-15, etc., in an integrated circuit 73 is over a specified threshold voltage, sensing of any over-voltage being generated is made by feeding a current to a resistance 81 and zenor diode 83 which are in series connection, and when over-voltage is sensed, it is divided by resistances 87 and 89. The integrated circuit 73 is driven by, this divided over-voltage, which will liberate the circuit 73 from impression of the over-voltage. Because, a resistance 81 is connected in series to the zenor diode 83, it 83 may be of type with small power capacity to lead to suppression of the cost.

Title: Emulator
Inventor: AKATSUKA HIROSHI
IPC: G06F11/28
Filed: 1995-05-26
Abstract: PURPOSE: To stop executing a program even if an address of a memory to be compared for a break dynamically changes during the execution of the program by stopping executing the program according to the result of a comparison between the contents of a dual-port memory and the contents of a break data storage area. CONSTITUTION: A dynamic address calculator 14 receives information showing that dynamically changing memory contents have changed from a variation memory monitor circuit 12, calculates the dynamic address changing during the program execution from the contents of a variation memory storage area 13 and a fixed value setting area 11, and stores it in a dynamic address storage area 15. Consequently, a break circuit 9 retrieves data stored in the dual-port RAM 16 in the past in the dynamic address when the contents of the variation memory area 13 are changed during the program execution. When the retrieved contents match the contents of the break data setting area, a break signal 10 is generated. With this break signal 10, an MCU 1 stops the program execution.

Title: Printing-controlling system

IPC: B41J29/387
Filed: 1985-06-14
Abstract: PURPOSE:To avoid consumption of electric power unnecessarily, by stopping excitation of a CR motor and an LF motor when long period of time is required for converting a character code into a dot pattern. CONSTITUTION:When starting printing, a CPU1 references data stored in an excitation mode designation register 8, and when the data indicate that a character code for a double-em character is contained in a document buffer 4 so that the mode involves stopping the excitation, no voltage is outputted to signal lines 10, 11, whereby excitation of the CR motor and the LF motor is momentarily stopped. The CPU1 reads character codes from the buffer 4, gives them to a character generator 6 on a character basis, and transfers dot patterns from a buffer 7 to a line buffer 2. When the dot patterns for one line are provided, the CR motor and the LF motor are excited. The double-em character means a character having a dot pattern size of 2aXa, aX2a or 2aX2a where the dot pattern size of an ordinary character is aXa.

Abstract: PURPOSE:To reduce readout errors of data due to the influence of pressing, a tape run flaw, dissidence of linearity, etc., and to shorten the readout completion time of retrieval data by recording retrieval data having the same contents at plural dispersed positions on the same track. CONSTITUTION:A track T1 on a video tape 1 is assigned to a chapter 1-1, T2 to a chapter 1-2, and so on T-16 to a chapter 3-4. Retrieval data C1-1 on the chapter 1-1 is recorded on, for example, the track T1 at four positions ar proper intervals respectively. Similarly, data C1-1-C3-4 are recorded on other tracks. The track T1 is scanned firstly and data C1-1 shown by No.1 when read out without any error is written in a memory. If data No.1 is an error, data C1-2 indicated by No.2 is read and written on the memory when having no error. Thus, readout errors of data due to the influence of pressing, a tape run flaw, dissidence of linearity, etc., are reduced and the readout completion time of inspection data is shortened.
