Abstract: PURPOSE: To enhance measuring accuracy, by shifting laser beam in the second direction crossing the first direction almost at a right angle at every scanning and comparing the signals at the places same in the position in the first direction at the time of each scanning to remove the signal based on a noise component.  
     CONSTITUTION: A slit beam source 12 is allowed to light and the slit image of a slit 14 is formed to the part containing the measuring point P of the anterior sac 11a through beam splitters 8, 10 and a lens 9 and the beam from a laser beam source 1 is condensed to the measuring point P. A part of the beam scattered at the measuring point P is turned toward an examiner 33 by a beam splitter 21 to perform observation and, at the same time, incident to a photomultiplier tube 27 through a lens 22, a prism 23 and a mask 26. Since the scanning due to laser beam in a horizontal direction is performed and a region to be measured changes at each time when vertical scanning is performed once. the positions of the peak P of the count value based on a noise component are respectively different in sections b1, b2. The count values per a unit time at the places same in the position in a vertical direction are compared at the time of vertical scanning and the min value is selected to make it possible to remove the noise component.

Abstract: PURPOSE:To make selective drive of a reel turntable with simple and small- sized constitution, by driving the reel turntable selectively according to the direction of revolution of a motor possible for forward and reverse operation through the adoption of a unidirectional rotating clutch. CONSTITUTION:Between a winding reel gear 35 and a follower rotating wheel 36, a clutch which can be delivered to the follower rotating wheel 36 only for the clockwise rotation of a winding reel gear 35 is provided and a supply reel turntable device is provided with a clutch function which can deliver only the counterclockwise revolution opposite to the winding reel turntable device. Thus, when a motor 28 is driven clockwise, a winding reel shaft 37 only rotates clockwise and no supply reel shaft 137 rotates. When the motor 28 is driven counterclockwise, the operation is entirely opposite. Thus, the reel turntable device can be selectively driven by only changing the direction of revolution of the motor.

Abstract: PURPOSE: To make highly effective the exposure work, by adding a simple hardware to the rectrangular electron beam exposing unit and by performing repetitive exposure for the basic unit pattern given by using this.  
     CONSTITUTION: The electron beams from the electron gun are passed through the first and second slits 5 and 8 in which the rectangular holes are placed, and the cross section of beam can be changed by the deflection of the size varying deflector 6 present between the slits. Next, deflection is made with the alignment deflector 10 and the beams are shrinded with the electron lens 11, then the wafer 12 is radiated. With this constitution, the deflectors 6 and 10 are controlled with a new hardware. That is, the central processing unit 21 controls the basic unit pattern data memory 22, designating the size and location of the pattern. Further, based on this information, the deflectors 6 and 8 are controlled by using the registers 28,29, adders 30,31, D/A converters 32 to 35, and amplifiers 36 to 39. Thus, after the exposure of a certain types of basic unit pattern, other types of patterns are exposed, allowing to increase the working efficiency.

Title: Still picture transmitter
Inventor: EMORI NORIO
IPC: H04N7/00
Filed: 1991-06-28
Abstract: PURPOSE:To easily know the presence or absence of a still picture file stored in a built-in memory or the number of files with no operation of keys in an automatic reception mode. CONSTITUTION:The portable still picture transmitters 1A and 1B are connected to each other via a telephone circuit 5. Each of both transmitters 1A and 1B contains an automatic receiving function and automatically receives the still picture files (still picture image data) transmitted from the same devices set at the separate points in an automatic reception mode and they are stored in a work RAM. The number of still picture files stored in a work RAM is shown on a display device 12 of each of both transmitters 1A and 1B in an automatic reception mode. The displayed number of files changes every time a still picture file is stored in the work RAM. Thus an operator can know the presence or absence of the still picture file stored in the work RAM or the number of stored files in an automatic reception mode just by seeing the number of files shown on the device 12 and with no complicated operation of keys.
