IPC: H01L29/812
Filed: 1991-04-22
Abstract: PURPOSE:To increase an effective mass of electrons in a surface direction of an InAs layer and to suppress generation of an impact ionization, etc., by applying a compression distortion in the surface of the layer. CONSTITUTION:First and second buffer layers 12, 13, a channel layer 14, a doping layer 15, and a contact layer 16 are sequentially laminated on a semi- insulating substrate 11, and a source electrode 17, a drain electrode 18 and a gate electrode 19 are formed to form a field effect transistor of a selectively doped structure. The layer 14 made of InAs is about 100 Angstrom of the degree of a limited thickness in which no lattice misalignment dislocation occurs. Thus, Since the InAs layer receives a large compression distortion in its surface, an effective mass of electrons is increased, and hence an increase in carrier density such as impact ionization, etc., can be suppressed.

Title: Color sensor
Inventor: KAKINUMA HIROAKI
IPC: H04N5/335
Filed: 1990-04-05
Abstract: PURPOSE:To obtain a photocurrent corresponding to the intensity of the component of incident light and to make it possible to identify the color of the incident light accurately by forming a B photosensitive layer and a G photosensitive layer so that thier thicknesses are thicker than the thicknesses which perfectly absorb the lights having the wavelengths in a blue region and a green region. CONSTITUTION:A G photosensitive layer and a B photosensitive layer having band gaps for the optical energies in green and blue regions are formed so that the layers have the thicknesses which are thicker than thicknesses that perfectly absorb the lights corresponding to the band gaps. Therefore, the blue and green components are perfectly absorbed with the layers 3 and 4. Carriers corresponding to the intensities are generated. Photocurrents are generated by voltages applied on electrodes 7a and 7b and 6a and 6b which are provided at the end parts of the upper surfaces of the layers 4 and 3. The parts which do not absorb light act as insulators. Thus the movement of the carriers into other photosensitive layer can be avoided. The photocurrents corresponding to the generated amount of the carriers can be taken out of the photosensitive layers. The color of the incident light can be accurately identified.

Title: Proximity aligner
Inventor: TANAKA TSUTOMU
IPC: G03F9/00
Filed: 1988-04-15
Abstract: PURPOSE:To obtain a product whose accuracy is high and whose yield is high by a method wherein reflected light from a substrate and a mask of light irradiated by means of an exposure and illumination apparatus is picked up by using a TV camera, its picked-up result is image-processed by using an operation and control means and an instruction to deform the surface of a substrate chuck is given. CONSTITUTION:A substrate 1 is first loaded on a substrate chuck 2; a mask 3 is lowered; a gap between the substrate 1 and the mask 3 is set to about several tens of mum to several hundred mum. Then, a measuring shutter 18 equipped with an interference filter 17 inside an exposure and illumination apparatus 4 is inserted into a light path; an opening and shutting shutter 16 is opened; the mask 3 and the substrate 1 are irradiated with a single wavelength or two wavelengths. Reflected light which has been reflected from a pattern face of the mask 3 and the surface of the substrate 1 generates an interference fringe. After a light path has been branched in front of the measuring shutter 18, the interference fringe is picked up into a TV camera 5. Then, three picked-up operations of the interference fringe are checked; the parallelism (an irregularity in the gap) over a whole face of the mask 3 and the substrate 1 is operated by using an operation and control means 7. On the basis of this result, piezo-elements 8 which are built in the substrate chuck 2 are driven by a drive circuit 11; the parallelism is obtained in such a way that the surface of the substrate 1 follows the surface of the mask 3.

IPC: B41J2/51
Filed: 1986-04-22
Abstract: PURPOSE:To enable a fixed uniform printed result to be automatically obtained irrespective of a position at which a paper is set, by detecting the left end position of the set paper by a distance-detecting means, and correcting a printing starting position designated by a program, based on distance data thus obtained. CONSTITUTION:For example, when the distance between the left end of a paper and a printing-starting position designated by a program is equivalent to a 7-character- position length and the setting position of the paper is deviated rightward by 5 cm, a detecting means 2 detects distance data corresponding to the position of a paper- feeding mechanism 12. The data is subjected to comparison and storing by a comparing and storing means 3, and the data thus processed is converted into character position information by a converting means 4. When the information thus obtained is N charac ter positions, a printing-starting position determining means 5 determines the printing starting position to be the (N+7)th character position from the left end of a paper setting area 14, and sends the determined value to a printing means 6. When a program having a printing-starting position (for example, the 10th character position) different from the above, distance data detected is not sent through the converting means 4, and the printing-starting position is determined to be the (N+10)th character position from the left end of the area 14.

Title: Mode filter
Inventor: OOTSUKA MICHIO
IPC: H01P1/162
Filed: 1983-05-26
Abstract: PURPOSE:To improve the selectivity of mode and to attain the attenuation of spurious mode by using a resistor having an anisotropy in a specific resistivity as a loss body. CONSTITUTION:A resistor 10 having an anisotropy in a specific resistivity, e.g., pyrolytic graphite is fitted onto the inner wall of a hollow support 4 in such a way that the direction having a smaller specific resistance is coincient with the direction of current of an electromagnetic wave of the transmission mode on an inner wall face of a waveguide. Since the direction having a small specific resistivity is orthogonal to the direction having a larger direction in general, a large resistance loss is produced in the mode having a current direction orthogonal to the current direction of the transmission mode and the current is attenuated. Thus, it is possible to improve the mode selectively by selecting a resistor having the large anisotropy of the specific resistivity and also the attenuation of the spurious mode is increased.

Abstract: PURPOSE:To lessen substantially an air gap between a second plunger and a magnetic stopper cap and thereby to speed up a motion, by putting a magnetic tubular body on the butting part of a non-magnetic second cylinder with the magnetic stopper cap. CONSTITUTION:When an overload current flows, a magnetomotive flux from a coil 12 flows to the left and right outer side plates 6 and 7 of a U-shaped yoke 5, a first plunger 3, a magnetic stopper cap 2 and a second plunger 9. Thereby the first plunger 3 is attracted and moved onto the side of the magnetic stopper cap 2, so as to compress an air gap with the second plunger 9 and finally to move the second plunger 9. At this time, a magnetic flux X of the yoke 5 is separated into a main magnetic flux X1 flowing from the right outer side plate 7 to the magnetic stopper cap 2 through a small-diameter part 11 and a large- diameter head part 10, and into a by-pass magnetic flux X3 flowing from the large-diameter head part 10 to the magnetic stopper cap 2 via a magnetic tubular member 18 interposed in the butting part of the second cylinder 13 with the magnetic stopper cap 2, and an air gap between the large-diameter head part 10 and the stopper cap 2 is lessened substantially by this by-pass magnetic flux X3.
