Title: Microwave drying device
Inventor: KURODA KIYOMITSU
IPC: F26B23/08
Filed: 1990-09-14
Abstract: PURPOSE:To permit temperature detection with good accuracy by a method wherein the temperature of materials to be dried is detected by a temperature detecting means for low temperature in the initial period of heating while the detection is switched so as to detect a temperature by a temperature detecting means for high temperature when the value of the temperature comes slightly before the upper limit of the detecting range of the temperature detecting means for low temperature. CONSTITUTION:Microwave is projected against materials 5 to be dried from a magnetron 12 through a wave guide 13 and the temperature of the materials is detected by a temperature detecting unit 17. When drying is advanced, the temperature of materials 5 to be dried is risen and the temperature, detected by a thermistor 17a for low temperature has arrived at a switching point A, a switching circuit 25 switches to the characteristics of a thermistor 17b for high temperature. The temperature of the materials 5 to be dried is detected thereafter by the thermistor 17b for high temperature. When the temperature of the materials 5 to be dried is risen and the temperature detected by the temperature detecting unit 17 has arrived at a predetermined value, the magnetron 12 is operated intermittently to keep the materials 5 to be dried at a given temperature and, thereafter, the drying is finished after a predetermined period of time.

Title: Mapping type electron microscope, semiconductor flaw inspection device and manufacture of semiconductor device
Inventor: KIHARA NAOTO
IPC: G01N23/225
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a mapping type electron microscope capable of suppressing the distortion aberration in a wide field of view and observing a sample with a high resolution. SOLUTION: The electron gun 1 of this mapping type electron microscope emits an electron beam as a primary irradiation beam 4 to irradiate a sample 6 placed on a stage 5. From the sample 6, secondary electrons, backward diffused electrons, and reflected electrons 8 are generated. These electrons serve as two-dimensional electron signals and are magnified and projected by a secondary optical system 9 to form an image on an MCP sensor 10, which is converted into light by a fluorescent screen 11, passed through a photo mapping optical system 14, and irradiated on a TDI type CCD camera 13, in which a TDI array CCD is mounted. The optical system 41 is designed, so that the distortion aberration generated in the secondary optical system (electronic mapping optical system) 9 sets off the distortion aberrations generated in the photo mapping optical system 14. Thereby the total distortion aberration of mapping type electron microscope becomes small, and the sample can be observed with high resolution.

Title: Purity correcting method for color cathode-ray tube
Inventor: TOSHIYASU MASAYUKI
IPC: H01J9/44
Filed: 1985-10-30
Abstract: PURPOSE:To perform a purity correction work easily and quickly by arranging a color cathode-ray tube under such environment as having no magnetic field in the direction of a plane including the tube axis while applying an alternating magnetic field having frequency different from the vertical deflection frequency onto the color cathode-ray tube in specific direction and arranging a correction magnet in the color cathode-ray tube. CONSTITUTION:When the beam landing is shifted to the left, an electron beam will impinge against a green fluorescent material, upon displacement to a position shown by a dot and dash line, so that color fringing which will appear with 10Hz period is generated. Variation of such color fringing will appear at each section not in just-landing condition, thereby an adjusting worker observing a raster 1 can confirm easily with eyes. Consequently, the adjusting worker is required to perform such work as to arrange a correcting magnet 13 on the outer face of a funnel corresponding to a portion having color fringing and to select the polarity intensity and the position for eliminating the color fringing for each portion having the color fringing. Consequently, purity correction suitable for the region using the color cathode-ray tube can be performed efficiently.

Title: Optical head device and liquid crystal lens used in the same
Inventor: TANABE YUZURU
IPC: G11B7/135
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To provide both lens function and diffraction grating function by one liquid crystal lens, to make a lens small in size and light in weight and to increase light availability by changing the lens function in the central part and the diffraction grating function on the peripheral part of the liquid crystal lens to each other with a voltage. SOLUTION: The phase control part 19 in the center of a liquid crystal lens changes the refractive index of the liquid crystal and the lens function by forming electrodes on the whole surface of both substrates 11, 12 and applying a voltage between the electrodes of two substrates. The grating-like electrode of an opening control part 18 on the periphery turns on/off the straight travel of light depending upon the state of voltage application, at the time of turning off the voltage, the liquid crystal molecule becomes the same arranging state and the light travels straight. At the time the voltage is turned on, the liquid crystal molecule rises in an electrode part and, a part the risen liquid crystal molecule and a horizontal part, appear alternately.  Consequently, a fringe-like part having different refractive index appeares, it functions as a diffraction grating and light is diffracted.

Abstract: PURPOSE:To speed up the memory access of a DRAM. CONSTITUTION:This DRAM is internally provided with two row-address buffer circuits 308, 322 and a selector circuit 323 which selects either one of these circuits. A CAS signal 313 is ascertained to start CAS before RAS refreshment during the precharging period of a RAS signal in a high-speed page mode and a refreshing address 321 is latched into a buffer 308 by the ascertation of the RAS signal 305 in the next memory access.

Title: Thin film magnetic head
Inventor: NISHIOKA KOICHI
IPC: G11B5/31
Filed: 1990-09-19
Abstract: PURPOSE:To eliminate a problem that a reproduced waveform is distorted or noise occurs after recording by reducing the reproduced output in accordance with the rise of an operating frequency by the structure where magnetization of a magnetic core is practically refluxed in a plane orthogonal to a magnetic path. CONSTITUTION:The front end of a magnetic core 1 has a refluxing magnetic domain structure in a plane orthogonal to a magnetic path 4. Since magnetization is refluxed in the plane orthogonal to the magnetic path 4, the magnetic core is magnetized by magnetization rotation because magnetization in any magnetic domain is orthogonal to the magnetic field from a medium, and a magnetic wall is not moved. Therefore, the discontinuous magnetization change does not occur and magnetization is easily operated at a high speed, and consequently, the reproduced waveform distortion is difficult to occur even if the transfer speed is increased, and the reduction of the reproduced output is reduced. Thus, the high frequency permeability of the magnetic core is increased, and a large reproduced output is obtained, and waveform distortion and noise after recording are difficult to occur.
