Title: Photomask blank and photomask
Inventor: TANAKA KEIJI
IPC: G03F1/50
Filed: 1995-04-18
Abstract: PURPOSE: To stably and productively provide a photomask with high pattern position accuracy and high quality by making a shading film material on a transparent substrate amorphous. CONSTITUTION: A shading film is formed on a transparent substrate and the material of the shading film is made amorphous. Amorphous means such a property that in the measurement using X-ray diffraction, the intensity of the diffraction line is very weak, the peak of the diffraction line is broad and indistinct, or the diffraction line has no peak, thereby making litative analysis of the material difficult to conduct from the diffraction line. Photomask blank in which the main component of the shading film is metallic chromium is preferable. By forming the shading film with an amorphous thin film (preferably chromium nitride thin film), characteristics such as mechanical strength and smoothness on the surface are satisfied and at the same time stress can be controlled.  As the preferable example, by using chromium nitride having a specified composition as a sputtering target or vaporizing raw material, amorphous chromium nitride thin film is easily formed.

Title: Shifter circuit
Inventor: MURATA HIDEMI
IPC: G06F12/04
Filed: 1985-04-30
Abstract: PURPOSE:To reduce the number of times of write by storing a consecutive pattern data twice the write unit to a register and extracting the write unit after prescribed amount of shift in writing a pattern data of a bit map memory. CONSTITUTION:A shift control circuit 12 discriminates a write command to registers A, B and shift direction and quantity from a shift sender and shift destination head address. A read signal read at 1 word each is stored alternately in the registers A, B from a write command from a bit map memory and inputted respectively in a shifter 10. The shifter 10 uses the shift command designating the shift quantity and shift direction so as to apply prescribed shift and outputs it two words in parallel. A multiplexer 11 selects alternately a high- order and a low-order shift output of the shifter 10 and outputs the output as a write signal of a shift destination. Thus, write information of consecutive pattern data is obtained after the shift and low cost is attained by the reduction in the number of times of write.

Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To enable continuous operation under a high pH condition by preventing the formation of scale within a system in making high purity water in a two-stage RO membrane separator. SOLUTION: A pH control agent is added to raw water to precipitate scale and, after scale is preliminarily removed by a membrane separator 4, alkali is added to raw water to perform the two-stage RO treatment of raw water. Or, a pH control agent is added to conc. water of a first RO membrane separator 2 to precipitate scale which is, in turn, removed by the membrane separator and treated water is circulated to a raw water side. Therefore, even if the first RO membrane separator 2 is subjected to high pH operation in order to preliminarily remove a scale component, the formation of scale is prevented. Further, treated water of high quality can be continuously produced over a long period of time.

Abstract: PURPOSE:To prevent that one's own position is changed discontinuously by a method wherein, when a combination of satellites used for a positioning operation is changed, data on a pseudo-distance is corrected regarding satellites which have been selected newly. CONSTITUTION:On the basis of the output from a satellite selection part 7, a distance computation part 5 judges whether a combination of satellites used for a positioning operation by means of the satellite selection part 7 has been changed over or not. When it is recognized that the combination has been changed over, the distance computation part 5 finds one's own position by means of the combination of satellites before the changeover. When a three- dimensional positioning operation is being performed, one's own position which has been found contains not only three-dimensional coordinates but also an inherent clock error DELTAT. The distance computation part 5 computes the distance R to a newly selected satellite from one's own position which has been found in this manner. A correction-amount computation part 6 finds a pseudo-distance R', the distance R and the inherent error DELTAR. A positioning computation part 4 corrects the pseudo-distance by using a pseudo-distance correction amount.
