Title: Lithography projection system and method for fabricating device
Inventor: BENSCHOP JOZEF PETRUS HENRICUS
IPC: H01L21/027
Filed: 2001-07-06
Abstract: PROBLEM TO BE SOLVED: To solve the problem of a lithography projection system for focusing a pattern on a mask onto a substrate using a projection beam from a radiation source that variation in the intensity of the projection beam causes variation in the line width of the pattern to result in a rejectable product and to provide a projection system in which variation of intensity is suppressed remarkably on the mask. SOLUTION: It is known that the major cause of variation in the irradiation intensity of a mask MA is relative movement of a projection beam PB in a direction perpendicular to the propagating direction caused by vibration of a supporting frame HP. Dose of the projection beam PB being received by a substrate W is made uniform by measuring the movement of the projection beam PB or a component through a measuring means MM and controlling a radiation source LA through a control means CM depending on the output from the measuring means MM or adjusting the position of the component through an adjusting means.

Title: Ice making device and vending machine equipped therewith
Inventor: TANAKA SATORU
IPC: G07F13/06
Filed: 2001-07-31
Abstract: PROBLEM TO BE SOLVED: To lessen a fall from a discharge opening of an ice making device to a cup, while ensuring the height of a cup takeout opening, thereby to facilitate takeout of the cup and also to improve the accuracy of detection of the weight of ice. SOLUTION: A vessel 40 temporarily holding the ice 31 delivered from the ice discharge opening 38 rotates around a pin 40a provided in the upper part of the vessel 40. Therefore, the ice 31 in the vessel 40 is cleared off after it is once lifted and so the fall from the ice discharge opening 38 to the cup is lessened. Since the height of the cup takeout opening is not lessened, the cup can be taken out easily. Since the weight of the ice 31 in the vessel 40 is detected, being balanced with a poise 48, nonuniformity in detection is small and the accuracy of detection of the weight of the ice is excellent.
