Title: Tungsten filament, which is hardly sagged, and lamp using said filament
Inventor: JIYON UIRIAMU PIYUU
IPC: H01K1/08
Filed: 1991-05-07
Abstract: PURPOSE: To improve strength under high temperatures and resistance to sagging by forming a filament structure into a microstructure consisting of a slender grain engaged and combined with each other which is regulated according to a grain shape parameter having a value of about 10 or more. CONSTITUTION: A double coil filament is formed by winding a tungsten filament wire having nearly 0% recrystallization around a primary and a secondary mandrel composed of molybdenum and steel. After annealing is applied thereto so as to control an elastic spring back, the double coil filament is taken out from the secondary mandrel and immersed into an acid bath to thereby dessolve the other mandrel. Thereafter, a recrystallization treatment is carried out to perform heating under the absolute temperature of 2650 deg. K for 30 seconds, then quenching is done up to a room temperature. Hereby, a grain shape parameter(GSP) having 10 or more is obtained. Further, a value of GSP is equal to one such that grain axis ratio(GAR) is divided by grain boundary factor(GBF) and it can be specified measured in a stated procedure with using a electron microscope.

Title: System for converting direction of integrated circuit
Inventor: TAKAHASHI HIROAKI
IPC: B65G47/244
Filed: 1984-06-25
Abstract: PURPOSE:To arrange the direction of integrated circuits automatically and easily by detecting the magnetic poles of the magnetized integrated circuit with a stop plate to rotate a transfer path rotating section on the basis of the detected magnetic pole. CONSTITUTION:When an integrated circuit (e) proceeds in the proceeding direction (g) on a transfer path (a) and is stopped by a stopper plate (b), the magnetic pole of the integrated circuit (e) is detected by a Hall element (c) mounted on the stopper plate (b) to judge whether or not it is a specified magnetic pole. If the detected magnetic pole is not the specified one, a drive motor (f) is controlled by a control circuit to rotate a transfer path rotating section (d) by 180 deg., lifts the stopper plate (b) after the completion of that rotation and send the integrated circuit (e) in the proceeding direction (g). Also, if the detected magnetic pole is the specified one, the rotating section (d) is not rotated and the stopper plate (b) is raised to send the integrated circuit (e) in the proceeding direction (g). As a result, the directions of all integrated circuits (e) are automatically arranged all in the same direction.

Title: Detector for protrusion of program area

IPC: G06F11/00
Filed: 1984-06-26
Abstract: PURPOSE:To produce an interruption to stop the execution of a program when a development progarm has an access to an access inhibition area, by providing a program key and an execution program level store area for each program. CONSTITUTION:The program key PK of a relevant area stores previously 1-3 in response to the levels of data on segments 101-104 respectively. In this case, however, a program Pm103 whicn is performing the debug is set at 0. While the level of the program carrying out the debug is stored to a program level flag 201 for execution of the Pm103. Here a PKm203 is set at 00 and therefore no INt signal 205 nor JUMP signal 206 are produced regardless of a program level Pl flag 201. If a bug exists in a program with a jump given to another segment, the signal INT205 is produced according to the PL of the jumping destination and when the PL is higher than the level of the flag 201. Thus the program actuation is stopped for prevention of the data destruction.

Title: Filtering for digital video signal
Inventor: BEATTIE ROBERT
IPC: H04N7/26
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To filter noise included in digital video signals so as to easily compress them. SOLUTION: Filter processes (11-13) are performed to video signals and signals are multiplied by a first variable gain coefficient. The delay sample of the signals is led out by a delay circuit and the delay sample is multiplied by a second variable gain coefficient. The two multiplied signals are added. The sizes of the two gain coefficients are different by the comparison of the delay sample from the delay circuit and the input video signals and the sizes of the two gain coefficients are changed in mutually opposite directions. By appropriately selecting the gain coefficients, the sharpness of the large transition part of image information is maintained by using the filter processes and the impulse response of a filter is easily changed by re-calculating the gain coefficients.  When the filter processes (11-13) are executed in a cascade type filter stage, filtering is achieved by two space regions and one time region.
