Title: Length measurement using electron beam
Inventor: KAWAMURA YOSHIHIRO
IPC: G01B15/08
Filed: 1989-03-09
Abstract: PURPOSE:To remarkably shorten the time for measuring the length of an object by making a cross section of an electron beam rectangular and by performing one time scanning of said object in a relatively wide range. CONSTITUTION:A scanning-type drawing apparatus 20 is provided with a first aperture 29 and a second aperture 32, so that a rectangular beam 36, not alike a very small round beam obtained by a conventional apparatus, can be formed. When a protruding part 10 of an object 11, e.g., an IC pattern is scanned by this beam 36, an increase of the radiating amount of secondary electrons from the object which is represented at an edge of the protruding part 10 is detected thereby to measure the width of the protruding part 10. In this case, since the width is measured over a certain range of the object, it becomes possible to considerably shorten the measuring time. At the same time, even if a very small defect is present at the measuring part, the measuring accuracy and reliability are never influenced thereby.

Title: Fluid controller of conductive fluid
Inventor: GOTO TADASHI
IPC: H02K44/04
Filed: 1985-03-25
Abstract: PURPOSE:To simply control fluid by providing a current suppressor to cause a current to flow to the magnetic circuit and to cause no current to flow to a current circuit when an electromagnetic fluid is stopped, thereby operating an electromagnetic brake action at stopping time. CONSTITUTION:In an AC Faraday type electromagnetic pump having a current circuit and a magnetic circuit perpendicularly crossing a duct 2, currents flow to the magnetic coil 10 of the magnetic circuit and the current transformer coil 7 of the current circuit when electromagnetic fluid is driven. When the fluid is stopped no current flows to the coil 7 and a current flows to the coil 10 by a current suppressor 13. Thus, since electromagnetic action is operated to the fluid at stopping time, it is not necessary to provide a mechanical movable portion such as a fluid regulating valve or a check valve to improve the reliability.

Title: Method for dehydrating activated sludge
Inventor: YOSHIDA TADAYUKI
IPC: C02F11/12
Filed: 1982-04-06
Abstract: PURPOSE:To prevent snaking of a filter cloth and to dehydrate activated sludge to be treated with good efficiency, over a long time by pressurizing the stationary filter cloth of a circular conical shape from the outer side thereof by turning pressurizing rolls so as to compress the sludge in the filter cloth thereby removing water to the outside of the filter cloth. CONSTITUTION:A receiving base 1 consisting of a metallic plate is inclined and fixed on a stand 2. A filter cloth 3 of a circular conical shape is fixed on the base 1 with the inlet part 3a thereof positioned upward and the convergent part 3b downward. When pressurizing rolls 4a, 4b are placed on the cloth 3 and are moved under rolling in a downward direction, the activated sludge contained in the cloth 3 is sandwiched between the rolls 4a, 4b and the base 1 by the loading of the rolls, and is thereby compressed. Thus, the water in the sludge is discharged through the fine pores of the cloth 3 to the outside and only the sludge remains in the filter 3. The water flowing out through the cloth 3 flows downward on the base 1 and is collected into a water collecting tank 5.

Title: Quench detector of superconducting coil
Inventor: INOUE KOICHI
IPC: H01F6/02
Filed: 1993-03-19
Abstract: PURPOSE:To detect a quench and then to increase a reliability by comparing the coil voltage with the voltage equivalent which is obtained by multiplying an hourly variation of coil current by inductance of the coil. CONSTITUTION:A superconducting coil 1 is provided with voltage taps 2a, 2c for detecting a quench and a current detector 8 for detecting current I to flow in the coil. Voltage appearing between the voltage taps 2a and 2c is sent to a voltage comparator 5a through an insulator 4. The current I detected by the current detector 8 is sent as a voltage signal to a terminal voltage measuring equipment 9, where the current is differentiated by time and then is multiplied by inductance to get the voltage, equivalent (L-dI/dt). The voltage equivalent is sent to the voltage comparator 5a. Thus, a highly reliable quench detector for a superconducting coil is obtained by which a quench can be detected even if two similar expansions of ordinary conductive sections appear at the same time on the superconducting coil.
