A glass panel comprising a pair of glass sheets (1, 2) disposed with respective faces thereof confronting each other in face-to-face relationship with a gap (V) therebetween and with peripheral edges of the glass sheets (1, 2) being bonded with a bonding sealant (4) to be sealed thereby; an evacuating port (5) for evacuating gas present within said gap (V) to the outside; and a getter (7) for coming into contact with the gas within said gap (V), wherein said evacuating port (5) includes a getter-retaining space (6) for retaining said getter (7) therein, said port (5) being formed in one (1) of said pair of glass sheets (1, 2), said getter (7) being retained within said getter-retaining space (6), said evacuating port (5) being closed and sealed by means of a lid (8). After the peripheral edges of the glass sheets (1, 2) are bonded and sealed by a bonding sealant (4), the gas present within said gap (V) is drawn and evacuated through said evacuating port (5) with said getter (7) being retained within said getter-retaining space (6), then, said evacuating port (5) is closed and sealed by bonding a lid (8) to said one glass sheet (1).

In order to control an internal pressure of an air spring appropriately without being influenced by a change in supply pressure, an anti-vibration system includes an air spring as an actuator for an anti-vibration table, a pressure control valve for controlling the internal pressure of the air spring, a pressure sensor for detecting the air supply pressure to the pressure control valve, a driving system for actuating the pressure control valve in accordance with a detection signal of the pressure sensor, and a variable gain compensation system for performing variable gain compensation to an input signal to the driving system for the pressure control valve, on the basis of the detection signal of the pressure sensor.
摘要:
A glass panel comprising a pair of glass plates opposed to each other with a void defined therebetween, a joining seal member for joining and sealing the glass plates at peripheries thereof, a communicating bore formed in one of the glass plates for communicating with the void and a lid member adhered to the bored glass plate having the communicating bore by a thermally meltable seal member to seal the communicating bore. The lid member is made of a material having a thermal expansion coefficient smaller than a thermal expansion coefficient of the bored glass plate. The glass panel is capable of restraining cracks and breaks from generating in the bored glass plate when the lid member is adhered to the bored glass plate by the thermally meltable seal member.
摘要:
A fluid compressor that ensures the discharge of water from a discharge port when water is drawn into or condensed in a pump chamber. The compressor includes a pump chamber for drawing in fluid. The pump chamber includes a bottom part located in a lower portion of the pump chamber. Two rotors arranged in the pump chamber are rotated to compress the fluid in the pump chamber. A discharge port located in the bottom part discharges the compressed fluid out of the pump chamber. The bottom part defines a guide surface formed continuously from the discharge port. The guide surface is sloped downward so that water on the guide surface moves downward to the discharge port due to gravitational force.

A vibration isolator includes a vibration isolation platform, a vibration sensor installed on the vibration isolation platform, and an angle sensor for sensing an inclination angle of the vibration isolation platform. A detection signal from the vibration sensor is corrected based upon an output from the angle sensor, and the corrected detection signal is used in order to suppress vibration of the vibration isolation platform.
