Title: Electron beam exposure device
Inventor: KUSAKABE HIDEO
IPC: H01L21/027
Filed: 1979-10-09
Abstract: PURPOSE:To conduct positioning accurately by a method wherein a sample base is moved by false pulses while electron beams are relatively deflected, an irradiating location is fixed and scanned, and the number of false pulses at a point of time when a mark is detected is obtained. CONSTITUTION:False pulses 17 are supplied to an X direction deflector 16 through an OR circuit 15 while being fed to an A/D converter 19. The deflector 16 independently deflects the pulses in the X direction. Thus, electron beams 11 are scanned in the X direction from an irradiating location relatively positioned to a material 13 to be exposed according to measuring pulses. When the beams 11 cross a mark 13a of the sample 13 by means of deflection, reflected electrons are generated, and the electrons are detected 18 and A/D converted 19. The false pulses are used as extracting clock, digital signals corresponding to the number of clock up to the rise and fall of detecting signals are emitted, and the signals are arithmetically processed 20. Thus, a mark location of the sample 13 is calculated, and the location is put out as positioning information. The same applies in the Y direction, and positioning can accurately be conducted.

Title: Automatic ticket examination device
Inventor: KOMORI MIKI
IPC: G07B15/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent a device from being damaged though a foreign matter is thrown in and to improve a processing rate as fast as possible by inhibiting the foreign matter from being taken into the main body of an automatic ticket examination device at the time of judging the throwing in of the foreign matter. SOLUTION: An inserted object inserted to an insertion port 1 is detected by a thickness sensor D1 provided on this side of a first separation part S1 and its detection signal is inputted to a controller C. When the controller C judges the thickness of the inserted object obtained by the thickness sensor D1 to be not less than 1.2mm, it is judged that a foreign matter except a train ticket is thrown into the insertion port 1. Then the motor M of a main carrying path L and motors m1 and m2 for a separation part S are abnormality-stopped to stop the taking in of the inserted object to the main body. Consequently the foreign matter is stopped at least on this side of a reading heads H1 and H1' to effectively prevent the reading heads H1 and H1' from being damaged by the foreign matters.

IPC: E02D15/06
Filed: 1985-06-18
Abstract: PURPOSE:To prevent the separation of a slurry by a method in which while a slurry flows out of a placing tube, the valve mechanism of the placing tube is controlled so that the amount of slurry to be supplied to the placing tube is equalized with the amount of the slurry to be flowed out of the placing tube. CONSTITUTION:While concrete 12 is supplied into the tube 14 of a placer 10, the concrete 12 in the tube 14 is allowed to flow out by opening the outlet of a valve mechanism 18. The opening degree of the valve 26 of the mechanism 18 is controlled, while the concrete 12 is placed, by a controller 22 for the mechanism 18 in such a way that the amount of concrete 12 to be discharged from the tube 14 is equalized with the amount of the concrete 12 to be supplied to the tube 14. The tube 14 can thus be kept filled with the concrete 12 to prevent the outflow of the concrete 12 with high speed under its own weight. The separation of the concrete 12 can therefore be avoided.
