Title: Molten carbonate fuel cell
Inventor: YOSHIOKA TAKATOSHI
IPC: H01M8/02
Filed: 1987-10-28
Abstract: PURPOSE:To increase the plastic working capability and corrosion resistance of a corrugated plate by previously applying heat treatment to the corrugated plate which is used in gas passages in a separator. CONSTITUTION:A fuel cell has an electrolyte body 1, electrodes 2, 3 arranged on its both sides, and separators 5 arranged on the outside of each electrode, and gas passages 8 in each separator 5 are formed with a corrugated plate 9. The corrugated plate consists of 0.15% or less C, 1% or less Si, 2% or less Mn, 16-35% Ni, 15-35% Cr, 0.1-0.9% Al, 0.5% or less Y by weight and the balance Fe and unavoidable impurities. Before the corrugated plate is formed, an original thin plate is heated at 950 deg.C or higher and quickly cooled to form an oxide film on its surface. Even after the corrugated plate was formed, the oxide film exists on its surface. The plastic working capability and corrosion resistance of the corrugated plate are increased.

Title: Sunshine sensor
Inventor: SUZUKI YASUTOSHI
IPC: G01J1/02
Filed: 1993-10-28
Abstract: PURPOSE:To achieve an upgrading of positioning accuracy of each part and mass producibility. CONSTITUTION:Two left and right pn junction parts 13L and 13R (p<+>layer) are formed on the top surface of an n<->type epitaxial layer 12 and electrodes 15L and 15R are formed thereon through an oxide insulation film 14 (SiO2), and an aluminum wiring is executed. Moreover, a light-blocking protrusion 16 is formed integrally at the center of the top surface of an Si substrate 12 being positioned between both the pn junction parts 13L and 13R. The protrusion 16 is formed by a photoetching of a p-type Si substrate on the top surface of the epitaxial layer 12. In this case, sunshine light incident into the top surface of a photodiode element 11 is blocked partially by the protrusion 16 so that a light-irradiated area corresponding to the top surface of the photodiode element 11 varies with the direction of sunshining (bearing or altitude of sunshining). Thus, output signals of the left and right pn junction parts 13L and 13R change accordingly, thereby the direction of sunshining can be judged depending on a difference therebetween.

Title: Cathode-ray tube
Inventor: IMANISHI WATARU
IPC: H01J29/50
Filed: 1985-11-29
Abstract: PURPOSE:To reduce scattering area of vapor deposition on the neck part without vapor-depositing molybdnum thereon, by forming an annular conductive lead out of a wire material whose core is made of molybdenum and surface is coated with a metal having a vapor pressure higher enough than that of molybdenum. CONSTITUTION:An annular conductive lead 15 is formed on the core made of molybdenum wire out of a wire material coated with a metal having a vapor pressure higher enough than that of molybdenum. Therefore, in a cathode-ray tube provided with such annular conductive lead 15, a vapor-deposited film 17 is formed upon exhaust process without having cupper which is evaporated by the heat of an electrode generated from a high frequency coil 16b. Further, as the evaporation starting temperature is 2,450 deg.C about 1,200 deg.C higher than that of cupper, 1,250 deg.C, if scattering of the heating temperature becomes larger due to scattering of the position of the high frequency coil 16b, the vapor- deposited film 17 can be formed by only cupper 19 coated on a core 18 without evaporating the core 18.

Title: Electric railroad switch
Inventor: OTOGAWA KATSUYOSHI
IPC: B61L7/08
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To provide an electric railroad switch that can transmit large torque by a magnetic coupling while being easily manufactured. SOLUTION: A driving magnetic coupling part 120 is composed of a first power transmission member 130 on the motor shaft 111 side, and a second power transmission member 140 on the output shaft 22 side. A magnetic coupling between the first power transmission member 130 and the second power transmission member 140 is formed of both parts for transmitting torque by the mutual attractive force of permanent magnets 132, 142 and attractive force between a permanent magnet 133 and a hysteresis magnetizing substance.  Since torque is transmitted from the driving side to the driven side by combining the mutual attractive force of the permanent magnets 132, 142 with attractive force between the permanent magnet 133 and the hysteresis magnetizing substance 143, large torque can be obtained while suppressing torque pulsation without extremely increasing the number of magnetic poles of the permanent magnets 132, 142, and since the number of the magnetic poles is not extremely large, an electric switching machine can be manufactured easily at a low cost.

Abstract: PURPOSE:To attain a red color with high color purity by exposing AC corona to a photosensitive body after the developing stage of magenta and in the electrification stage of cyan in case of transferring on paper after forming a color image on the photosensitive body. CONSTITUTION:The black signal of a negative is exposed on the photosensitive body 40 with a semiconductor laser 42 so as to form an electrostatic latent image. Thereafter, signal light corresponding to yellow is exposed to form the electrostatic latent image of yellow.

Then, the photosensitive body 40 is made to pass a cyan developing device 28 and a black developing device 38 in non-developing states. Next, it is exposed by an AC corona electrifying device 44 to form the electrostatic latent image of cyan, so that the color image can be completed. After transferring the color toner image obtained on the photosensitive body 40 onto paper 46 by a transfer electrifying device 45, the image is fixed by heat by a fixing unit 47.

IPC: H01L21/607
Filed: 1988-10-28
Abstract: PURPOSE:To achieve equal press-contact bonding strength through obtaining the same oscillation amplitude even if the oscillating characteristics of transducers are different by correcting the ultrasonic oscillating voltage applied to the transducer by means of an output from a computer. CONSTITUTION:A current 1a fed back from a transducer 1 is converted to a digital value by an A/D converter 10 and input to a computer 5. The computer 5 computes the difference of the characteristics of the transducers 1 and corrects the input set data so as to achieve the same ultrasonic oscillation and supplies output data 5a to a control circuit 11. The circuit 11 controls an oscillating voltage 6a input from an ultrasonic oscillating circuit 6 and supplies it to the transducer 1. Thus, the same oscillation amplitude can be obtained even if the oscillating characteristics of transducers are different, so that equal press- contact bonding strength can be achieved.

Title: Device for detecting number of person
Inventor: HORII TAKASHI
IPC: G06M11/00
Filed: 1987-10-27
Abstract: PURPOSE:To stably detect the number of person with high accuracy by obtaining an input waveform as a referring waveform when there is no human body to be detected, detecting person number information from difference between both waveforms and prohibiting the updating of the referring waveform with an external signal and the output of the person number information. CONSTITUTION:An infrared detecting element 2 is scanned by a scanning optical system 1 and the output is supplied through an amplifying part 3 to a signal processing part 4. The processing part 4 obtains the input waveform, when the human body does not exist, as the referring waveform and stores it to a storing part 41. Then, when there is no updating prohibiting signal from an external part, the referring waveform is updated by an updating part 42 and the difference between the input waveform and the referring wave form is obtained in a comparing part 43. A deciding part 5 counts the person number information from a differential waveform by a counting part 51. Then, when there is no output prohibiting signal from the external part, an output control part 52 outputs a counted result to an output part 6. Thus, the updating of inconvenient referring waveform and the fluctuation of person number output can be prevented and the number of person can be stably detected with the high accuracy.
