Inventor: KAWACHI MASARU
IPC: H01L21/36
Filed: 1990-09-28
Abstract: PURPOSE:To improve characteristics of single crystal, by arranging polycrystal of II-VI compound semiconductor at a high temperature part of a crucible arranged in a sealed tube provided with temperature difference, forming an Li2Se atmosphere at a specified temperature in the crucible, and turning the polycrystal into single crystal by solid growth. CONSTITUTION:Polycrystal ZnSe which is an example of raw material 12 to be turned into single crystal and Li2Se which is dopant 13 for turning the original material into conductor are put in a crucible 11, which is put in a sealed tube 14 made of quartz as heat resistant material. The inside of the sealed tube is vacuumized at about 10<-6> Torr, and the top part of the tube is fused and sealed. The crucible 11 is so placed in a heating furnace that the crucible bottom part where the original material 12 and the dopant 13 for conductor are disposed is at the high temperature part, and the top part of the crucible is at the low temperature part of the heating furnace. In this state, heat treatment for, e.g. about two weeks is performed. Thereby the polycrystal line ZnSe as the raw material 12 is almost turned into single crystal.

Title: Magnetic resonance imaging apparatus
Inventor: YAMAGUCHI KOJIRO
IPC: A61B5/055
Filed: 1992-09-25
Abstract: PURPOSE:To enable the obtaining of an image without artifact with higher accuracy of unwinding encoding. CONSTITUTION:In a magnetic resonance imaging apparatus, in which an unwinding encode gradient magnetic field is applied to turn a phase encode value to zero after the correction of each echo, a phase encode gradient magnetic field for a first echo is made equal in the intensity to the unwinding encode gradient magnetic field so that the phase encode for the second echo is down to zero. Under such a condition, the unwinding encode gradient magnetic field of the first echo is changed to detect a signal intensity of the second echo and the unwinding encode gradient magnetic field to minimize the signal intensity is determined as the unwinding encode gradient magnetic field with respect to the first echo. Likewise, the intensity of the encode gradient magnetic field is determined for the echos following the second echo.

Title: Fault simulation system
Inventor: NAGAI MASAHIKO
IPC: G06F11/26
Filed: 1989-10-02
Abstract: PURPOSE:To perform high speed processing by transforming the logic of a logic circuit so that the logic agrees with the predetermined basic form of a gate, forming fault control data indicating the correspondence with an assumed fault position before the transformation of the logic, and injecting the fault into the logic circuit after the logic transformation. CONSTITUTION:The gate data for all the gates are stored in a gate-data memory 611. The addresses of the gates wherein events are propagated among all gates are stored in an event table 610. An element-function retrieving part 601 loads logic function data 402 in the memory 611 which are specified with the addresses in the table 610 into a vector register 620. An input-value reading part 602 loads the logic values 1 - 3 of all gates which are retrieved from the table 610 into the respective vector registers 620. In a logic operating part 603, the logic operation specified with the register 620 with respect to the logic value of the register 603 is performed. The result is stored in the register 620. The table 610 and a next event table 612 are changed, and the same process is repeated. Thus, the number of the input and the output of the basic gate is formed as 3, and the high-speed processing can be performed by the vector instruction.

Filed: 1986-10-30
Abstract: PURPOSE:To insert a reply character string without intermitting the operation of a data transmission circuit by designating a control data representing at the outside of a block check character arithmetic operation to a control informa tion area corresponding to a transmission buffer where a communication control program is divided into sections. CONSTITUTION:A data transmission circuit 3 sends transmission data in small buffers 131-13m to a line by the instruction of a 2nd control memory 2 and applies BCC (Block Check Character) generating operation after a specific character as a start character in the sent data. In this case, when the communi cation program 11 sets full duplex communication reply character to a specific small buffer, the control data designating to be a data at the outside of the object of BCC generating operation is set to control information areas 141-14m corresponding to the set small buffers 131-13m. Thus, while the circuit 3 sends the data of the specific small buffer, since the BCC generating operation is stopped, the possibility of production of intervention request to the communica tion control program is precluded and the communication efficiency is improved.
