Title: High purity nitrogen gas manufacturing apparatus
Inventor: YOSHINO AKIRA
IPC: F25J3/02
Filed: 1988-12-12
Abstract: PURPOSE:To manufacture high purity nitrogen gas continuously by a method wherein a gas holder is provided in the top portion of a doom ceiling of a rectifying column, and its one end is connected to the rectifying column and the other end to the atmosphere to discharge impurity gas. CONSTITUTION:The ceiling inside a rectifying column 15 is formed into a doom shape, and the middle of the doom ceiling is expanded so as to form a gas holder 22. An outlet pipe 27 is provided on the upper circumferential wall of the rectifying column 15, and opens in the tangential direction. The nitrogen gas in the rectifying column 15 is taken out from the pipe 27, causing the nitrogen gas to circle along the inner circumferential wall of the doom ceiling in the circumferential direction as shown by the arrows A, so that the nitrogen gas having a larger molecular weigh is transferred towards the circumferential side by centrifugal force and He and H2 having smaller molecular weight is retained in the center portion. As a result, He and H2 as impurity are separated from the nitrogen gas. The separated He and H2 gases are stored in the gas holder 22 and discharged to the atmosphere through a discharge pipe 22a.

The T can be expressed by an equation and K value applying the maximum value to (t) is set up as K1. Then the right end point [P1, K1(P1-a) + f(a)] of the found straight line is defined as a start point and the same operation is repeated to find out the broken line of the succeeding section. Thus, the P and K are successively deterined, and when the value P reaches the right end point (b) of the applied function, the operation is ended.

Title: Coordinate input device and its input pointor
Inventor: MURAKAMI AZUMA
IPC: G06F3/03
Filed: 1988-12-15
Abstract: PURPOSE:To omit a cable, etc., for an input pointor containing a tuning circuit by producing the radio waves to the pointor via a position detecting part to obtain the coordinate value of a position pointed by the pointor from the radio waves reflected from the turning circuit and at the same time to obtain the change of a tuning frequency as the change of a phase. CONSTITUTION:When the radio waves are produced from a radio wave generating means 7 of a tablet, a tuning circuit of an input pointor 2 reflects the radio waves. The reflected radio waves are detected by a radio wave detecting means 14 of the tablet and sent to a coordinate detecting means. Then this detecting means detects the coordinate value of a point pointed by the pointor 2 in both X and Y directions. In this case, the radio waves detected by the means 14 have the frequency and phase errors in response to the operations of the pointor 2. These errors are detected by a phase detecting means of the tablet as the phase change. Then this phase information and the information obtained from the coordinate value of the pointed position are displayed on a display device. Thus it is not required to connect a cable, etc., to the pointor 2.

Title: Electron beam welding method for low alloy steels
Inventor: NAYAMA RISUKE
IPC: B23K15/00
Filed: 1988-12-15
Abstract: PURPOSE:To subject a bond part to the formation of the finer grains after recrystallization and to improve toughness by subjecting base metals to welding of the 2nd pass at a specific distance from the center line of the weld metal of the 1st pass and further to welding of the 3rd pass at a specific distance from the center line of the weld metal of the 1st pass. CONSTITUTION:The groove part of the base metals 1, 1 consisting of low alloy or resembling component steels is subjected to electron beam welding to form the weld metal 2A of the 1st pass. The position apart by 2H from the center line of the weld metal 2A is then subjected to the electron beam welding under the same conditions to form the weld metal 2B of the 2nd pass. The H which is the reference for the spacing between the welding pass positions is the distance between the region where the weld heat affected part is subjected to the formation of the finer grains after the recrystallization and the bond part. Further, the position apart by H in the same direction as the direction of the 2nd pass from the center line of the weld metal 2A of the 1st pass is subjected to the electron beam welding under the same conditions to form the weld metal 3C of the 3rd pass. The coarser grains are formed in the bond 3 part of the 1st pass and the 2nd pass and the finer grains are formed after the recrystallization by the heat cycle arising from the welding of the 3rd pass. The toughness is thereby improved.

Title: Driving method for step motor
Inventor: NITTA NOBORU
IPC: H02P8/00
Filed: 1992-11-26
Abstract: PURPOSE:To allow prorection of a switching element against heating by allowing a comparator to be switched to a prohibition signal having such level as allowing chopping control of the switching element. CONSTITUTION:When high current drive operation is desired, switching is made to output a prohibition signal Vint using a current value setting means 30. Since the levels of coil current corresponding detection signals Vac, Vbd never exceed the level of the prohibition signal Vint, comparators 25ac, 25bd are not inverted thus outputting no trigger signal Tac, Tbd. Consequently, AND gates 23a to 23d can creat and output control signals CNTa to CNTd continuously throughout the interval when phase switching signals Pha-Pad are inputted. This constitution allows high current drive operation while prohibiting chopping control and protects switching elements 21a to 21d against overheat by eliminating accumulation of heat due to chopping control.
