Abstract: PURPOSE:To improve a pulling up speed by forming the inside surface of an upper chamber to a shape to reflect and concentrate the radiation heat from a heater and a melt surface to a region where the melt surface and the inside surface of a crucible housing the melt come into contact. CONSTITUTION:The shape of the inside surface of the upper chamber 7 is formed to the shape to allow the reflection and concentration of the radiation heat 18 and 19 from the surface of the melt 12 and the heater 4 to the region 13 where the inside surface of the quartz crucible 1 and the surface of the melt 12 come into contact. The region 13 is locally subjected to heat insulation and the temp. of the melt 12 is maintained higher than the temp. at a crystal growth boundary 14. The melt 12 is, therefore, prevented from starting solidifying from the inside surface of the quartz crucible 1 even if the quantity of the heat that the melt 12 receives from the heater is decreased (is guided to the direction where the temp. over the entire part of the melt is lowered). The pulling up speed of a single crystal 11 is easily adjusted to a high speed.

Filed: 1987-05-12
Abstract: PURPOSE:To prevent the mutual interference among plural positioning units by adding an encoder to the servo motor of each positioning unit to detect the stop position of the unit in the absolute value and connecting each encoder to a sensor switch circuit having a different power supply from that of the servo motor. CONSTITUTION:The brakes B1-B6 are provided to the servo motors M1-M6 of positioning units U1-U10 respectively to damp the motors M1-M6 in response to a case where these motors are de-energized via a power switch circuit 6. At the same time, the encoders E1-E6 are also added to the motors M1-M6 to detect the stop positions of these motors in the absolute values. The encoders E1-E6 are connected to a sensor switch circuit 11 having a different power supply from that for those servo motors. Thus these motors are surely stopped by the brakes B1-B6 respectively so that the servo rigidity is maintained. In addition, the encoders can always monitor the position information on the motors M1-M6 despite the break of the power supply of these motors. As a result, the occurrence of mutual interference can be avoided among those units U1-U6.

Title: Microwave discharging light source device
Inventor: UMAGOME KAZUO
IPC: H01J65/04
Filed: 1986-05-20
Abstract: PURPOSE:To quicken luminous operation and prevent a lamp from being broken, by disposing a screen part in the middle of a lamp supporting part and sending a cooled wind so that the cooled wind passes through the screen part toward a non-polarity lamp. CONSTITUTION:A screen part 93 is disposed in the middle of a lamp supporting part 91, that is, between a lamp outer wall part 92 and a fixture 10. A cooled wind is made to flow away from the part, where the lamp supporting part 91 is mounted projecting to the lamp wall part 92, owing to the screen part 93 in existence, while the other portion of the lamp wall part is cooled. Therefore, a coolest-point temperature rises, so that sealed-in materials such as inert gas and mercury are rapidly vaporized at a start of operation to quicken luminous operation. Temperature difference also becomes small over the whole wall part of the lamp 9, and therefore reducing difference in vapor density. And, a discharge kept away from the bulb wall prevents the lamp 9 from being broken.
