Title: Solar timepiece with illumination
Inventor: SATO KOICHI
IPC: G04B19/30
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To overcome the problem that, in a solar timepiece with illumination in which a solar cell and an EL light-emitting layer are provided on the lower surface of a translucent character plate at which an hour character is formed, a character plate around the hour character is illuminated and the hour character is hard to be recognized because it is blurred when the EL is lit as the hour character is in the shadow if it is small, resulting in posed limit on design. SOLUTION: A pointer display type timepiece comprises an illumination device such as an LED panel 5 with a solar cell 1 as a drive source. The solar cell is disposed under a translucent region 2 of a character plate 1 while the illumination device is disposed under an opaque region 3 with an opening. By using the opening as the hour character 4, a solar clock with illumination which is excellent in design can be presented. The opaque region 3 and the hour character 4 are printed to provide the hour characters such as a figure.

Title: Substrate processor
Inventor: TSURI MAKOTO
IPC: C23C16/44
Filed: 2001-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent byproducts from being deposited near a furnace port without laying a heater. SOLUTION: On an upper surface of a seal cap 23 of a furnace port opening/ closing device 21 for opening and closing the furnace port 16 of a mainfold 15 of a process tube 11, a shower head 30 for blowing gaseous nitrogen 52 like a shower is installed. In supplying a film formation gas 51, when the gaseous nitrogen 52 is blown off like a shower from the shower head 30, a gaseous nitrogen atmosphere 53 as a byproduct preventing gas atmosphere is formed in an area above the seal cap 23, the film formation gas 51 is blocked from being in contact with a surface of a processing chamber side end face area of the seal cap 23, and thus the byproducts are prevented from being deposited on the area.  Thus, since deposition of the byproducts near the furnace port is prevented, generation of particles due to peeling of a deposited film is prevented and a manufacture yield or the like is improved. Since the need of laying the heater is eliminated, a load lock chamber can be constructed for a boat carry-in/carry-away chamber.

Title: Digital pll with gear shift
Inventor: STASZEWSKI ROBERT B
IPC: H03L7/093
Filed: 2001-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a PLL which does not require a dynamic range of a large phase error. SOLUTION: A PLL synthesizer (100) includes a gear-shifting scheme of the PLL loop gain constant α. During frequency/phase acquisition, a larger loop gain constant α1 is used so that the resulting phase error is within limits. After the frequency/phase gets acquired, the developed phase error of a rough indication of the frequency offset is in a steady-state condition. While transitioning into the tracking mode, the DC offset is added to the DCO tuning signal, preferably the DC offset is added to the phase error signal, and the loop constant is reduced from α1 to α2. This scheme provides for hitless operation, while requiring a low dynamic range of the phase detector (101).
