IPC: F25B43/04
Filed: 1991-12-17
Abstract: PURPOSE:To improve the efficiency of paradium cell acting as a means for discharging hydrogen gas. CONSTITUTION:A palladium cell 24 for use in discharging hydrogen gas is mounted at a non-condensing gas tank 23 in which non-condensing gas such as hydrogen gas generated within an absorption freezer is separated by a gas- liquid separating tank 22 and at the same time a cooling pipe 37 is arranged in such a way as an inside part of the tank is cooled by a part of refrigerant liquid accumulated at the bottom part of an evaporator 14.

IPC: G06F3/12
Filed: 1999-12-14
Abstract: PROBLEM TO BE SOLVED: To provide a printing device and a printing control method and a recording medium with a printing control program for preventing wastage of paper sheets by executing error processing at detection of print data not being appropriate for a printing mode set in a device body. SOLUTION: An error detecting part 13a detects the generation of errors from the appearing state of a line feed code or a page feed code in print data. Also, a printing mode deciding part 12 decides the printing mode of the device main body for print data received from a PC 5, and a level deciding part 12a decides a determining level to be used for error detection, corresponding to the certainty of the decided printing mode. Therefore, it is impossible to perform error detection processing according to the operative environment of the device main body. Thus, it is possible to prevent an image which is not intended by a user from being printed on large amounts of paper sheets, and to prevent the user form being annoyed by suppressing any wasteful error notification or printing stop.

Title: Image processor and image data processing method
Inventor: YASUHARA MASATERU
IPC: G06T7/00
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of recognition error by unnecessitating the test of correlative value evaluation due to a sample image by dynamically changing a correlative threshold value. SOLUTION: A correlation search is performed as shown by a broken like by turning registered image data 16 to 18 through a template and calculating a correlative value relating two images while successively moving this template 18. At such a time, the correlative value is operated by a matching engine. In this case, the correlative threshold value (prescribed reference value) is dynamically changed. Namely, concerning the moving amount to template 18, it is not moved every time for one pixel but simple correlative operation is performed by rough search at the interval of several pixels. Then, the rough search is performed again with the threshold value of (1/2), for example, to the used correlative threshold value and when no error occurs, precise search is performed with the threshold value of [(1/2)+(1/2<n> )].  Then, the distribution figure of provided correlative values is retrieved so that the optimum correlative threshold value showing the degree of coincidence between images can be determined.

IPC: B22F1/00
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To obtain uniform W-Cu type bulk solid solution composed essentially of bulky solid solution having larger volume than granular body by forming powder composed essentially of W-Cu solid solution. SOLUTION: At the time of manufacture, first a raw material mixture consisting of W powder and Cu powder is prepared. The mixing proportion of respective powders is determined so that the composition of the W-Cu solid solution to be finally obtained becomes W1-x Cux (where 0.05<=x<=0.5 is satisfied). Then, mechanical alloying treatment is carried out to form a powder composed essentially of W-Cu solid solution. By this procedure, the alloying action of W powder and Cu powder and the uniformizing action of them can be sufficiently provided, and a W-Cu solid solution powder as a nonequilibrium substance that is impossible to obtain by the melting method can be obtained.  By applying an impact pressure not lower than the yield stress of the solid solution to the resultant solid solution to compact it instantaneously, the powder can be solidified without causing phase separation and recrystallization. As the result, the W-Cu type bulk solid solution, containing bulky solid solution having diameter and volume larger than those of granular body, can easily be mass-produced.
