Title: Low pressure rare gas discharge lamp device
Inventor: NISHIKATSU TAKEO
IPC: H01J61/76
Filed: 1982-03-31
Abstract: PURPOSE:To obtain stable lighting of a lamp without a flicker, by turning on the lamp mainly emitting light of krypton with a current at least a high frequency limit current corresponding to seal pressure of the lamp. CONSTITUTION:A low pressure rare gas discharge lamp is constituted such that krypton or mixed gas containing krypton and consisting of the rest part of at least one of argon, neon and helium is sealed in a discharge lamp vessel at least 0.5Torr and not higher than 8Torr to mainly emit light of krypton, and this discharge lamp is turned on by a high frequency lighting device with a frequency at least 5kHz further with a current peak value Iop(A) (O-peak current) Iop >=1.2/P0.5 for seal pressure P(Torr) of the lamp. Pressure of seal gas less than 0.5Torr is unsuitable because an electrode decreases its life further with a large limit current, while the pressure exceeding 8Torr is unsuitable because luminous efficiency decreases. Further a lighting frequency of the lighting device, if low, is considered to cause a change of ion density and change the limit current.

Title: Pipe cutting tool
Inventor: JO HIROYUKI
IPC: B23D21/14
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent a rotary cutter from vibrating in an offset condition in a space formed between both holders during cutting operation by providing offset vibration preventing means for restraining the offset vibration of the rotary cutter to the holder part according to any one of the conditions of point contact and linear contact. SOLUTION: Each contact part 24 of a pair of holders are brought into linear contact with a surface 34 to be put in contact therewith of each rotary cutter 30. Since a function of limiting the offset conditions of the cutter 30 along the axial direction or vibrations thereof to a specified narrow range which is allowed to generate in a small clearance is given, each cutter is hard to vibrate in the space formed between both holders 22, 22 during the cutting operation by a pipe splitter and the like at the time of changing a pipe. Accordingly damage in the edge of rotary cutter 30 caused by the twisted condition of cutter 30 to the already cut part of such as a steel pipe is less apt to occur.

Abstract: PURPOSE:To position a tray into its carrying-in position with a simple mechanism by providing an elastic piece to a feed gear for driving the tray, abutting the elastic piece against an abutting part on the side of a player in the carrying-in position and energizing the tray with a reaction force in the carrying-in direction. CONSTITUTION:The elastic tongue piece 76 having a projection part 76a at the tip is provided underneath the feed gear 63 for horizontally driving the tray, while a protruding stripe 55 is provided to the lower surface of a cam gear 49. At the time of carrying the tray in, even when the gear 63 is turned by rotating the gear 49, the gear 63 is, however, idled because the tongue piece 76 is not brought into contact with protruding stripe 55. When the tray is almost brought in, the projection part 76a of the tongue piece 76 is brought into contact with the outer side surface of the protruding stripe 55. On completion of carrying the tray in by further turning the gear 49, the projection part 76a is brought into slide contact with the protruding stripe 55 by bending the tongue piece 76. Consequently, the gear 63 is energized by the reaction force from the tongue piece 76 in the tray carrying-in direction. By this method, the tray is brought into press contact with a boss for regulating the carrying-in position, thus positioning the tray in the carrying-in position.

Title: Arithmetic processing unit
Inventor: NOJIRI MINORU
IPC: G06F11/28
Filed: 1985-03-20
Abstract: PURPOSE:To improve the debug efficiency by producing an interruption after a branch instruction is executed. CONSTITUTION:A branch instruction decoding output signal JMP is masked by a mask gate 9 when the corresponding mask bit MBJ of an interruption mask register IMR 8 is equal to '0'. Then the next instruction is executed after a branch instruction is executed. However the gate 9 is satisfied by '1' of the signal JMP and '1' of the bit MBJ and a branch interruption request signal JIRQ is delivered to a control part 7. When the corresponding mask bit MBJ of an interruption mask resister IMR 8 is equal to '0' then an interruption request signal HRG is accepted immediately after execution of a prescribed branch instruction through the part 7. Thus a software interruption is produced immediately after execution of the branch instruction for easy production of debug data. This can avoid such a case where a console is occupied for a long period of time for a debug job.
