  • Patent number: 4734923
    Abstract: A device used to test the features of a mask used in a semiconductor lithographic machine. The device includes an array of charge couple devices and an array of pinholes positioned above the charge couple devices. The array of pinholes includes a small pinhole opening for each of the charge couple devices in that array and the size of each opening is dependent upon the resolution of the mask features desired to be inspected. The array of pinholes and the array of charge couple devices are moved in unison in discrete steps, related to the size of the pinhole openings, across an area of the mask related to the center to center spacing of the charge couple devices of the charge couple device array. By reading the data of each of the charge couple devices after each step, a comparison can be made against data previously obtained from a known good mask and a determination can be made whether the mask under test is acceptable or flawed.

  • Patent number: 4719798
    Abstract: A wind direction finder for use on a golf course includes a fastener portion and a ribbon portion which is attached to the fastener portion. The fastener portion includes an adhesive material having a peel away sheet, which when removed, allows the wind direction finder to be attached to the canopy frame post of a golf cart, preferably on the portion at an angle away from a line perpendicular to the ground. As the wind freely blows between the main body of the golf cart and the canopy, the wind lifts the free end of the ribbon, and the angle and direction of the ribbon can be observed by the golfer to indicate both the direction and speed of the wind. With this knowledge, the golfer can make appropriate compensations in the golf shot to be made. The fastener portion includes an interior member having the adhesive on one side thereof and a backing member and the ribbon is affixed between the interior member and the backing member.

  • Patent number: 4692934
    Abstract: Disclosed herein is a X-ray lithography system in which X-rays are generated by a laser beam focused upon a target within an evacuated chamber to create a soft X-ray emitting plasma which also emits debris particles. A thin sheet of X-ray transparent gas is provided between the target and a mask used in the lithographic process to displace the particles away from the mask. The sheet of gas may also be used to maintain a pressure differential across an opening in the evacuated chamber through which the X-rays pass towards the target. In addition, the gas sheet may be used to cool the X-ray mask by placing the mask close to the sheet but at a sufficient distance so that the sheet does not interfere with the mask.

  • Patent number: 4683724
    Abstract: Described herein is apparatus and a method for eliminating water trapped in a refrigerator system. The apparatus includes means to insert heated, dry gas, such as nitrogen, into the low side valve of the refrigeration system. The gas may be to a temperature between 175 and 220 degrees F. and is inserted until the pressure of the gas within the system is equal to between 35 and 65 PSI. The device includes appropriate temperature and pressure metering means for controlling both the temperature and pressure of the gas inserted. After the heated nitrogen gas is inserted into the refrigeration system, the compressor is turned on and allowed to run for approximately ten minutes and the heated nitrogen gas absorbs any water vapor in the refrigeration system. Thereafter the high side valve is opened and the escaping nitrogen containing the absorbed water escapes from the system. Then the refrigerant is added and when it begins escaping from the open high side valve, the high side valve is closed.

  • Patent number: 4665710
    Abstract: Described herein is a refrigeration defrost cycle monitoring and bypass circuit which monitors the condition of the defrost terminator switch. More specifically, the circuit monitors whether the defrost terminator switch is stuck in either the open or the closed position. This is accomplished using timers to determine the period of time of the defrost cycle and the period of time the terminator switch is open. If either of these times exceed preset values, the defrost terminator switch function is eliminated from the circuit and the control it normally performs is substituted by predetermined times. This occurs by providing a resettable ground to the defrost relay so that it can sense the need to defrost and initiate a defrost cycle. After a defrost cycle is initiated, a user selectable timer ends the defrost cycle after the selected time.
