Title: Daylighting device
Inventor: YOKOYA RYOJI
IPC: F21S11/00
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a stable quantity of daylight throughout the day, with a relatively simple arrangement. SOLUTION: Two primary reflecting mirrors 11, 12 are secured at their respective lower ends to the rotating shafts 4a of rotation means 4 placed near the edges of both east the west sides of a daylighting opening 3, which their respective mirror surfaces 1a pointed upward or toward the daylighting opening 3. Thus, rotation of the rotating shafts 4a by a motor or the like enables the primary reflectors 11, 12 which are secured to the rotating shafts 4a to be rotated in the east-to-west direction.  When the primary reflecting mirrors 11, 12 are tilted a predetermined tilting angle and reflect sunlight horizontally or vertically downward beyond the horizontal, light reflected by secondary reflecting mirrors 21, 22 enters a daylighting opening 3 by passing closer to the secondary reflecting mirrors 21, 22 than to focal points which are set near both the east and west ends of the daylighting opening 3 on a plane containing the daylighting opening 3. Therefore, a stable quantity of daylight can be obtained efficiently throughout the day with a relatively simple arrangement.

Title: H-bridge power amplifier for motor
Inventor: MARK K TAKITA
IPC: H03F3/217
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To obtain a high performance linear PWM amplifier which exhibits low harmonic distortion. SOLUTION: This amplifier includes four interconnection power transistors that are connected to an inductive load. Each transistor is provided with a voltage clamp with high accuracy which is connected between a source and a drain and suppresses ringing vibrations.

Title: Excimer laser beam machine
Inventor: AMANO MASANORI
IPC: A61F9/008
Filed: 1991-12-28
Abstract: PURPOSE:To easily perform maintenance on the title machine without requiring any exclusively-used nitrogen cylinder by using the liquid of an inert element for the cooling means of a gas recovering device and, at the same time, constituting the cooling means of a tube for introducing the vaporized inert gas to a light introducing optical system from the cooling means. CONSTITUTION:A light introducing optical system 2 is covered with a box 8 made of transparent glass plates, but the emitting end of the optical system facing operating eyes 3 has no glass plate and is opened to the outside. The box 8 is filled with a nitrogen gas supplied from a supplying means and a nitrogen gas flow is formed toward the front side of an objective lens 7. The reason why the nitrogen gas is supplied to the box 8 is to prevent the occurrence of such a trouble that the power of laser light is attenuated by ozone generated in the air by the laser light. The nitrogen gas is supplied to the box 8 by means of a pump 15 through a tube 13 while the flow rate of the gas is controlled through a valve 14. Since the nitrogen gas is supplied by a fixed flow rate, a flow is generated in the box 8 toward the operating eyes 3.
