Title: Automatic frequency tuning of mr device
Inventor: HALAMEK JAMES A
IPC: G01R33/389
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for automatically tuning the radio frequency transmitter and receiver of a magnetic resonance imaging device to an optimum frequency. SOLUTION: A magnetic resonance signal is converted into a frequency shift area to calculate the spectrum strength of the signal (106). For the spectrum strength, gravitational interpolation is effected (110) to obtain the desired frequency sampling. A model function is made in accordance with the strength of a main magnetic field having peaks separated by the same boundary as the boundary between fat and water signals. The spectrum strength is correlated with the model function (112) to search therefrom the peak having the maximum strength. The position of the peak of chemical species along the spectrum strength is anticipated from empirically acquired information, the strength of the main magnetic field, and the position of the correlation peak (114).  The region of the spectrum strength to be checked is made clear from the empirically acquired information (116), and the nearest peak in the region to the anticipated position is searched (118).

IPC: C10L1/182
Filed: 1992-11-30
Abstract: PURPOSE:To produce gasohol by a simplified process which can accomplish marked reduction of energy consumption and requires low cost of building by subjecting an ethanol/water mixture and gasoline to countercurrent extraction under conditions of specified temperature and specified pressure and cooling the gasoline phase to separate it into a water phase and a gasohol phase. CONSTITUTION:A crude alcohol of a concentration of 10-20wt.% enters a feed line 1, is preheated in heat exchangers 2 and 4, and fed to the top of a countercurrent alcohol extraction tower 6 through a feed line 5. gasoline preheated in heat exchangers 15, 11 and 21 is fed to the bottom of the tower 6 through a feed line 7. Because of its good affinity for gasoline, the ethanol in the water phase is selectively extracted with the gasoline phase (at an extraction temperature of about 80 deg.C or above). The temperature of the gasoline phase leaving the tower 6 through a line 10 is lowered to 10-60 deg.C to effect the phase separation of the water and to thereby markedly decrease the water content of the gasoline phase. Substantially, water-free gasohol is with-drawn from a line 14, cooled, brought into a state of atmospheric pressure by means of a pressure reducing valve 16 and fed to a gasohol storage tank 18.

Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To securely perform summarized printing using print characters which can be discriminated by eliminating the output of print characters which can not be discriminated owing to the summerized printing. SOLUTION: The size of print characters which can be decided are registered as criteria for decision making by a readability decision part (S1). With an expansion indication for data of a text by a DDI control part, whether or not the character size is reduced through a summarizing process and the expansion size are confirmed (S2). When is decided that the registered size is equal to or less than the expansion size in a process S3, it is decided that the characters can be decided and a printing process is performed. When the registered size is larger than the expansion side, the characters can not be decided, so the DDI control part is informed that the print characters can not be discriminated as a next process (S4). The DDI control part displays a notice or error message to an application program and guits the printing process.

Title: Semiconductor integrated device
Inventor: IBARAKI AKIRA
IPC: H01L21/822
Filed: 1988-12-20
Abstract: PURPOSE:To improve breakdown strength toward destruction against overvoltage by connecting one terminal to a positive side wiring, connecting the other terminal to a negative side wiring, and providing a protecting circuit whose breakdown strength is lower than that of function circuits in a chip. CONSTITUTION:In addition to a first power source protecting circuit 6a in the vicinity of a Vcc pad 1, a second power source protecting circuit 6b whose breakdown strength is lower than that of functional circuits in a chip is arranged in the vicinity of a Vss pad 2. In this way, current paths for absorbing overvoltage are increased into two paths, and the current capacity of wirings is increased. Therefore, the resistance between a power source and the Vss can be decreased, and the electric charge supplied with the overvoltage is made to flow as a short-circuit current in an early period. Thus the overvoltage can be absorbed. The breakdown strength toward destruction against the overvoltage that is applied to the terminals of the power source can be enhanced.
