Title: Solid photo-electron device
Inventor: MATSUKUBO TAKASHI
IPC: H01L31/10
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To increase an output energy even with a small solid photo-electron device for better detection of a weak light than usual, by allowing the light (electromagnetic wave) incident on a photo-electric conversion region to repeat reflection between the photo-electric conversion region and reflective film. SOLUTION: The external light condensed toward a photo-electric conversion region 2a with a on-chip micro lens 11 before passing a color filter 10 transmits a transmission/reflection film 7, and then comes into the photo-electric conversion region 2a. A part of the light incident in the photo-electric conversion region 2a is converted into paired electron-positive hole while the remaining part is repeatedly reflected as a light (electromagnetic wave). Here, the transmission/reflection film 7 plays a reflective function. The photo-electron is multiplied as converted into electric signal while reflection is repeated. Thus, a large output is provided even with a small size of a solid photo-electron device.

Title: Detecting apparatus of defect of characteristic of semiconductor laser
Inventor: NOZAKI GAKUO
IPC: G01R31/26
Filed: 1991-01-21
Abstract: PURPOSE:To remarkably improve the inspection of products in a reduced time and to express the recognizing degree of the classifying result by numerical values, by detecting and classifying defective waveforms of the differential L-I characteristic with the utilization of learning of a neural net. CONSTITUTION:This characteristic defect detecting apparatus for a semiconductor laser automatically detects and classifies the L-I kink at an optional position of the measured differential L-I characteristic which is not indicated with the use of a feature detector which detects the change of the differential L-I characteristic and the learning/weathering ability of a neural net. The neural net after learning detects and classifies defects of the waveform only by inputting the waveform data thereto. Therefore, the unnecessary calculation for prediction of a straight line can be saved if a straight part is not present in the waveform. The read time when products are inspected can be improved remarkably. Moreover, output units of an output layer can be assigned respectively to categories of good/defective products and noises. The maximum values of the units simultaneously indicate the reliability of the judgement, so that the recognizing degree of the classifying result can be expressed by numerical values.

Title: Fuel cell
Inventor: NAKAZAWA TETSUO
IPC: H01M8/04
Filed: 1982-01-18
Abstract: PURPOSE:To enable the breakage of electrodes and electrolyte plates which might be caused due to separators to be prevented by preparing the gas flow- path part of the separator, which is positioned on the outer side of a pair of  electrodes between which the electrolyte plate is interposed, from three-dimensionally net-like porous metal. CONSTITUTION:A separator for the fuel cell is prepared by three-dimensionally arranging a net-like porous metal in a separator frame. The above separator is placed on the outer side of a pair of electrodes between which an electrolyte plate is placed so as to form a constitution unit for the fuel cell, and thus formed cell units are practically used by being stacked. As a result, owing to the above porous metal, current collecting and supporting of electrodes can be securely performed. Besides, since reaction-gas flow paths formed by arranging the porous metals have a small draft resistance, the flow of gas becomes homogeneous.

IPC: G02B6/122
Filed: 1991-01-21
Abstract: PURPOSE:To provide the small-sized optical scanning element which does not require movable parts, such as rotating mechanisms, is simple in constitution and is high in productivity. CONSTITUTION:The optical scanning element 10 is constituted of a Ti diffused waveguide 14 which is produced by dispersing Ti, etc., into a substrate 12 consisting of LiNbO3, etc., having an electrooptical effect and plural electrodes 16 which are formed on both sides thereof. A bent waveguide 20 is so produced that the curvature increases gradually in the propagation direction of light. The light 38 is no longer confined in the waveguide and is radiated to the outside of the bent waveguide 20 by impressing a voltage to the electrodes 16 to decrease the refractive index of the bent waveguide 20. Then, the radiation direction of the light in the bent waveguide 20 is controlled by changing the magnitude of the voltage to be impressed to the electrodes 16.

Title: Production unit for beltlike silicon crystal
Inventor: MAKI NAOAKI
IPC: H01L21/208
Filed: 1982-01-18
Abstract: PURPOSE:To prevent the occurrence of a crystal asymmetry like a crevice, by forming the thickness of a pair of dies asymmetrically, making crystal nuclei occur in one direction from one die to the other. CONSTITUTION:Each of the thickness of a pair of the dies 11a and 11b is formed in such a way that the thickness of one of the die 11a is extremely larger than the other die 11b. The radiant doses Q of each of the dies 11a and 11b are  equal, and the temperature of the dies 11a and 11b are higher than that of the  silicon melt 3. Consequently, the temperature distribution of the beltlike silicon  5 at the solid-liquid interface 12 has a negative gradient from the die 11b side to  the die 11a side. Therefore, the occurrence of crystal nuclei is advanced from  the die 11a side to the die 11b side, and twins are passed from the low-temperature side to the high-temperature side without causing a crystal asymmetry like  a crevice. A thickness ratio of a pair of the dies 11b and 11a is (1:5)-(1:10), and  the difference of the temperature between the dies 11a and 11b at the solid-liquid interface of the growing silicon crystal 5 is 3-5 deg.C.

IPC: H04N1/29
Filed: 1978-01-24
Abstract: PURPOSE:To prevent the occurrence of uneven recording by applying voltages of different levels even to adjoining electrodes at the time of forming electrostatic latent images by applying voltages to one set of recording electrode group and auxiliary electrodes directly opposing thereto. CONSTITUTION:At the time when a negative voltage is applied to a recording electrode group a1 and at the same time a positive voltage is applied to its counter electrode b2 and b3, a voltage of a slightly lower level is also applied to their adjoining electrodes b1 and b4. Similarly, at the time of applying a negative electrode to a recording electrode group a2 and a positive electrode to the auxiliary electrodes b4 and b5 opposing thereto, a voltage of a slightly lower level is also applied to their adjoining electrodes b3 and b6. If electrostatic recording is performed by repeating the application of voltages to the respective electrodes in this way thereafter, the elimination of uneven densities wherein the densities decrease at the end parts of the recording electrode groups may be achieved.

Title: Detection of corrosion of steel structure
Inventor: MASUKO YORYO
IPC: G01N29/04
Filed: 1985-01-17
Abstract: PURPOSE:To make possible the quick detection of corrosion in a wide region by making incident an ultrasonic wave to a specimen at the angle at which the reflection is repeated back and forth on the front and rear of the specimen and comparing the received sound pressure of the transmitted wave thereof and the received sound pressure in a defectless part which is preliminarily measured. CONSTITUTION:The ultrasonic wave released from a probe T for signal transmission passes through water 3, a vinyl film 4 and a contact medium 5 between the vinyl film and the specimen in a locally water-immersing pot 2 and is thrown diagonally into the specimen 1. The ultrasonic wave arrives at the bottom end of a probe R for reception while repeating reflections on the front and rear of the specimen 1. The wave passes through the medium 5, the film 4 and the water 3 in the pot from the bottom end of the probe R and is converted to a voltage signal by the probe R. If there is corrosion LF on the ultrasonic wave reflection surface of the specimen, the ultrasonic wave is scattered at that point and finally the received sound pressure is smaller than the sound pressure when there is no corrosion on the reflection surface. The received sound pressure of the defectless part is therefore measured preliminarily and the case in which the measured value of the specimen is considerably smaller than the received sound pressure of the defectless part is judged to be the presence of the corroded part.
