Title: Beam interrupting device of accelerator
Inventor: MORII YASUJI
IPC: H05H7/00
Filed: 1988-05-12
Abstract: PURPOSE:To obtain a long-lived beam breaking device having a high movement speed by providing a current breaker between an electromagnet for generating a magnetic field forming an orbit of a charged particle beam and an electromagnet power source. CONSTITUTION:A thyristor switch 12 is used as a current breaking switch. The switch 12 is generally in off-state, and the current from an electromagnet power source 11 entirely flows into an electromagnet 1 to form such an electric field as forming the beam orbit 3 in the equilibrium state. When a beam breaking command is received, the switch is turned on, and the current from the power source 11 passes through the switch 12 and a protective resistance 13, but hardly flow into the electromagnet 1. Thus, the energy accumulated in the electromagnet 1 is attenuated by the circuit composed of the electromagnet 1, the switch 12, and the protective resistance 13. As the electromagnet current is reduced in this way, the beam fails to turn by the deflecting electromagnet 1 and collides with a vacuum duct 2 as the beam orbit 4 in the beam breaking, and thus the beam is interrupted. Hence, a long life and a high breaking speed can be achieved.

Abstract: PROBLEM TO BE SOLVED: To reduce an effective value of impression voltage to a discharge lamp when no load is applied by outputting a unbalanced rectangular wave AC voltage at unlighted time, and superimposing at least a single high voltage pulse on the high polarity side of at least a voltage peak value. SOLUTION: Lamp voltage is detected by a lamp voltage detecting circuit 18. As a result, when a lamp state is a unlighted state, a switching element Q0 operates so that the on-duty becomes wide in one polarity of rectangular wave output and becomes narrow in the other polarity by a PWM control circuit 5. As a result, DC voltage different in a voltage peak value is outputted from a boosting chopper circuit 3 to become rectangular wave voltage having an unbalanced peak value by a rectangular lighting circuit 2. A high voltage pulse required for starting/restarting a lamp is impressed at least by one on the high polarity side in a peak value of at least rectangular wave voltage by an igniter circuit 19 triggered by voltage impressed on the both ends of the lamp.

Abstract: PURPOSE:To simplify the controlling system of a shaft-sealing apparatus, by discharging low-temperature water by operating a temperature-control trap attached to a condensation tank, thereby maintaining the temperature of a shaft-sealing chamber to a prescribed level. CONSTITUTION:High-temperature steam is introduced from a steam-supplying source 5 into a shaft-sealing chamber 3 and the steam released from the chamber is introduced through a pipe 12 into a condensation tank 13. Hot water condensed in the condensation tank 13 is returned through the pipe 12 to the shaft-sealing chamber 3 to effect the shaft-sealing of the chamber 3 with steam and hot water. A temperature-control trap 18 is attached to the condensation tank 13 via a pipe 17. When the fluid temperature in the condensation tank 13 is lowered below a prescribed level, the trap 18 is opened to discharge the liquid, upon which high-temperature steam is introduced from the steam- supplying source 5 to raise the temperature of the shaft-sealing chamber 3 and the condensation tank 13. The temperature of the shaft-sealing chamber 3 can be controlled to a prescribed level by this process.

Abstract: PURPOSE:To form a semiconductor laser whose life is long by a method wherein an AlGaAs light-emitting layer is formed so as to be sandwiched between AlGaInP layers. CONSTITUTION:An n-type Al0.5Ga0.5As clad layer 2 and a p-type Al0.5Ga0.5As clad layer 4 are formed on an n-type GaAs substrate 1 so as to sandwich an active-layer waveguide layer 3; in addition, the current construction and the transversal-mode control structure by an n-type GaAs current-blocking layer 6 are provided. A low-resistance ohmic contact is formed on a p-type GaAs cap layer 5. The active-layer waveguide layer 3 is constituted of the following: a multilayer film formed in such a way that three GaAs well layers 9 sandwich two GaInP barrier layers 10; and a p-type GaInP guide layer 12 and an n-type GaInP guide layer 11 which have been formed on both outer sides of the multilayer film. Since the growth and the migration velocity of a crystal defect are slow as compared with the AlGaAs layer, the guide layers and the barrier layers restrain the crystal defect from creeping to the active layer, and a semiconductor laser whose lige is long can be obtained.

Title: Radiant heating device for low position warming
Inventor: MINAGAWA EIJI
IPC: F24J3/00
Filed: 1988-05-13
Abstract: PURPOSE:To facilitate the maintenance by generating medium- and low- temperature air with a high draft pressure by the use of a high pressure frictional blower and making the air release the heat from an array of heat- releasing panels. CONSTITUTION:The actuation of a high draft-pressure frictional blower 1, which is composed integrally of an electric motor and a casing housing an impeller, causes a rise in temperature to somewhere in the range of 20-80 deg.C with pneumatic operation. A blow header 3 distributes into heat-releasing panels 21...2n in an array a high pressure draft which the high pressure frictional blower 1 delivers from its outlet 1a and through a delivery pipe. Each of dampers 6, which regulate the draft both in pressure and quantity, is adjusted to have an optimum damper opening by a control means which actuates it on the basis of data from temperature sensors disposed at various positions. With this heating system, the temperature at the surface of the floor can be adjusted to 20-30 deg.C without being conditioned by the particularity of the site.

Title: Print control circuit of thermal printer
Inventor: FUJII SHUJI
IPC: B41J2/255
Filed: 1985-05-28
Abstract: PURPOSE:To attain more clear printing at the high print letter quality mode and high speed printing at a conventional dot pattern by providing the high print quality mode where two adjacent heaters make print while dividing the same dot twice and the high speed print mode where the two heaters print every other dot in the line direction. CONSTITUTION:In the high print quality mode, after preceding heaters A, C preheat a transfer film or heat sensing paper at print dot position, succeeding heaters B, D heat the paper to the final print temperature. That is, since one dot is hated twice by the two heaters, the power application time per heater is short and sharp print with less dot blur is applied. In the high speed print mode, the heaters A, B and C, D print simultaneously each individual dot. Thus, since one heater shares one dot, the power application time of the heaters A, B is longer, each other dot in the line direction in applied, then the print period is shortened to speed up the print.
