Title: Automatic brightness/contrast adjusting system of electron microscope
Inventor: YAMADA ATSUSHI
IPC: H01J37/244
Filed: 1991-04-26
Abstract: PURPOSE:To make automatic adjustment of brightness and contrast. CONSTITUTION:A reference histogram table 9 contains a reference histogram for various reference images specified previously and parameters for defining the gain and DC level. A control device 8 prepares a histogram by taking in the image data for the specimen written in a frame memory 7 and counting the number of picture elements per brightness. The histogram is compared with the reference histogram registrated in the reference histogram table 9, and a reference histogram the most similar to the prepared histogram shall be selected. The gain to be given to a gain adjusting circuit 3 and the DC level to be given to a DC level adjusting circuit 4 are determined based on parameters, which have been written in correspondence to the selected reference histogram.

Abstract: PURPOSE:To project a high brightness image by arranging the light emitting center of a lamp at the sharing point of a parabolic mirror and a spherical mirror which share an optical axis and are disposed opposite to each other so that the focal point of a paraboloid and the center of the curvature of a spherical surface are used as a sharing point, and providing rectangle opening on the spherical mirror. CONSTITUTION:A light source 1 is composed of the lamp 120, the parabolic mirror 130, the spherical mirror 140, and the rectangle opening 141. On the other hand, the parabolic mirror 130 and the spherical mirror 140 are disposed opposite to each other so that the focal point of the paraboloid and the center of the curvature of the spherical surface are used as the sharing point. The lamp 120 is disposed so that the light emitting center 121 is positioned at the sharing point position. Then, the rays of light emitted from the lamp 120 are directly reflected on the parabolic mirror 130, and emitted from the rectangle opening 141 as the rays of the light parallel to a center line 20, or reflected between the parabolic mirror 130 and the spherical mirror 141 and emitted from the ractangle opening 141 as the rays of the light parallel to the optical path 20. Thus, the loss of a luminous flux is prevented, and higher brightness image can be displayed.

Abstract: PURPOSE:To enable a stable supply by a conventional feeder by covering the surface of ferrite particles with a silane coupling agent and polyvinyl pyrrolidone, and thereafter blending them into a thermoplastic resin, thereby significantly reducing the adhesion among the particles. CONSTITUTION:After covering the surface of ferrite particles with a silane coupling agent and polyvinyl pyrrolidone, they are blended into a thermoplastic resin. The ferrite particles are the particles of a metal compound represented by a general chemical formula Fe2O3MO (M is a bivalent metal). The silane coupling agent is a compound which is typically expressed by a formula X- Si(OR)8, where X represents a functional group which reacts with organic materials, and which includes, for instance, an amino group, a vinyl group, an epoxy group, a mercapt group, chloro-group and the like. Polyvinyl pyrrolidone is obtained by polymerizing N-vinyl-2-pirrolidone, and typically that of a molecular weight of the order of 10,000-400,000 is used. With this, the adhesion is substantially reduced, whereby an ordinarily used feeder, for instance, a weight feeder, coil feeder or screw feeder can be employed.

Title: Protective system for power converter
Inventor: ASANO YUMIKO
IPC: H02H9/04
Filed: 1991-04-03
Abstract: PURPOSE:To protect low rated voltage components of a power control means against breakdown upon conduction failure of a control rectifying element constituting a step-down chopper. CONSTITUTION:A voltage detector 21 detects the voltage between the anode and cathode of a first control rectifying element 3 connected, together with a second control rectifying element 4, in series between the positive and negative electrodes of a DC power supply 1. Thus detected voltage is fed to a conduction failure detector 22 which decides conduction failure of the first control rectifying element 3 if thus detected voltage is zero regardless of the fact that a controller is delivering a switching state control signal to the first control rectifying element 3, and then the switching state control signal is delivered to the second control rectifying element 4.

IPC: G05F1/67
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To enable high-precision stable power feeding by operating a DC-DC converter consisting of a plurality input power sources, shifting the phase of each operation timing of a plurality of switches for switching its input current on/off, and to prevent the generation of a simultaneous operation period. SOLUTION: In a DC-DC converter which uses a solar battery and a commercial power source as input power sources, a starting circuit 11 detects a reset signal of an inductor L and outputs an operating signal as a starting signal, and a first oscillator circuit 12 computes the overall operating period Ton, on the basis of a constant-voltage control signal generated by output voltage detection. Next, a switch operation control circuit 13 outputs an operation period signal Ton1 for a solar battery side switch based on a battery cutoff control signal and an optimum operating point tracking signal for the solar battery, and a signal Ton-Ton1 corresponding to an input power deficiency due to this.  Here, a second oscillator circuit 14 outputs an operation period signal Ton2 for a commercial power source side switch whose phase of operation timing is shifted from that of the operation period signal Ton1.

Filed: 1993-03-31
Abstract: PURPOSE:To instruct a set tool angle at a precise angle by comparing data on a stored stopping position with current data, and driving a drive shaft in the direction of advance or retreat from the finishing position of manual operation. CONSTITUTION:When data ADT on the current position of a drive shaft which has been driven to a second interpolation point or a final interpolation point by a command to continue manual operation coincides with data on a stored stopping position, a stop command is temporarily output to finish manual operation. When the data are not coincident, a command to repeat a step is output to employ a step 160 for recognizing the coincidence of the stored stopping position, whereby a step 110 for computing the second interpolation point is executed. If a command to restart manual operation is input while manual operation is finished by a command to stop manual operation in a step 150, manual operation is started and the drive shaft is driven in the direction of advance or retreat from the position at which manual operation has been stopped in response to a command to stop manual operation, so as to control manual operation of a robot.
