Title: Subtraction image forming apparatus
Inventor: SHIMURA KAZUO
IPC: A61B6/00
Filed: 1992-03-09
Abstract: PURPOSE:To obtain radiation image information of an area on an image which overlaps a marker, in a subtraction image forming apparatus in which the marker is used. CONSTITUTION:Radiation image information of an object 43 where at least a part of image information is different is stored and recorded together with markers 60A, 60B having radiation absorbing characteristic equivalent to that of the bones of a human body, in two storage-type phosphor material sheets 30A, 30B. Excitation light 52 is radiated to the respective storage-type phosphor material sheets 30A, 30B where two radiation images of an object to be subjected to subtraction are respectively stored and recorded. Thus, the generated accelerated phosphorescence emitted light is detected by a photo detecting means 50 to obtain two image data which are different from each other at least partially. According to those image data, subtraction for image data for erasing the bone tissue is performed between pixels corresponding to the respective images to obtain a signal for forming an image of the specified structure of a radiation image where images of markers are erased together with those of the bone tissue.

Abstract: PURPOSE:To quickly execute a relative alignment operation between a mask and a substrate during a pattern transcription process by using a step-and-repeat method, by a method wherein a photoelectron-emitting face in a region to form an alignment pattern is irradiated by using a light source which is different from another light source to irradiate the photoelectron- emitting face in another region to form a pattern to be transcribed. CONSTITUTION:An electric field and a magnetic filed parallel to the electric field are impressed on a space between a photoelectron-emitting, face 7, which adheres closely to a mask 2 where a pattern to be transcribed and two or more alignment patterns 5 are arranged at the circumference of the pattern, and a substrate 4 arranged to be face to face with the emitting face; the photoelectron-emitting face 7 is irradiated with a beam of light; the pattern to be transcribed is transcribed onto the substrate 4 by using photoelectrons emitted from the photoelectron-emitting face 7. At this photoelectron-applied transcription method, a photoelectron-emitting face 71 in a region where the alignment patterns 5 are formed is irradiated selectively with beams of light 8, 81 from a light source which is different from another light source which irradiates the photoelectron-emitting face 7 situated in a region 200 where the pattern to be transcribed is formed; an alignment operation between the mask 2 and the substrate 4 is executed by using photoelectrons 9 which are emitted from the photoelectron-emitting face 71.

Title: Analysis of silica in water and pretreatment apparatus used therein
Inventor: HASE USHIO
IPC: G01N21/75
Filed: 1994-03-22
Abstract: PURPOSE:To determine silica in ultrapure water by ionic and nonionic forms. CONSTITUTION:An ammonia soln. is charged in a reaction vessel 1 and a sulfuric acid soln. is put in a reaction vessel 11 and the sample soln. in a sample container 26 is sent by a pump 27. The sample soln. absorbs the ammonia component transmitted through a wall of a gas permeable membrane tube 2 during the passage through the gas permeable membrane tube 2 and nonionic silica is decomposed by alkali during passage through the tube 22 to become ionic silica. Next, the ammonia component absorbed by the sample soln. permeates through the wall of the gas permeable membrane tube 12 during the passage through the tube 12 to be absorbed into the sulfuric acid soln. in the reaction vessel 11 to be removed. The outflow soln. from an outflow port 29 and the untreated sample soln. are determined by absorptiometry based on molybdenum blue color development to determine total silica and ionic silica. Nonionic silica is calculated from the difference between both analyzed values.

Title: Pressure sensor
Inventor: ISHII OSAMU
IPC: G01L9/00
Filed: 1989-03-02
Abstract: PURPOSE:To prevent a protection from effect of thermal distortion associated with a change in an ambient temperature by arranging a pressure sensitive element separately from a force transmission member deflecting section and a power transmission member while it is bridged securely with a pressure sensitive fixing member disposed within a pressure sensor housing. CONSTITUTION:A measuring force is converted into a force with a force converter such as bellows and applied to a pressure sensitive element 5 through a force transmission member 4 to detect a measuring force from a variation of an oscillation frequency at the pressure sensitive element 5. The pressure sensitive element 5 is arranged saparately from a force transmission member deflecting section and the force transmission member 4 while bridged securely with a pressure sensitive element fixing member 7. This prevents effect on the pressure sensitive elements caused by a thermal distortion associated with a change in ambient temperature thereby enabling suppression of possible distortion associated with a temperature change.

Title: Positioning system for original point
Inventor: ONDA NOBUHIKO
IPC: G05D3/12
Filed: 1985-03-14
Abstract: PURPOSE:To improve the positioning accuracy and to shorten the positioning time of an original point by controlling the speed up to a target position and thereafter controlling the position of the original point. CONSTITUTION:A ball screw feed device consists of the guides 13 and 14 set between a frame 16 and a support frame 11, a ball screw 15, a mobile part 10, etc. The screw 15 is revolved by a drive motor 20 attached to the frame 11, and a mobile part 10 is moved. Then a reference signal (Z-phase signal) ZS given from an encoder 21 and a detecting signal LS given from a limit sensor 22 are supplied to a control part 3. The motor 20 is switched between the speed control and the position control. In this case, the speed control is carried out until the signal LS is produced to continue the high-speed drive to a target position. Then the position control is performed every step when an original point is positioned for detection of the edge of the signal ZS. Thus it is possible to perform the positioning of the original point at a high speed and high repeating accuracy.
