Title: Cage of sight-seeing elevator
Inventor: MIYAMOTO TAKEROU
IPC: A63G31/00
Filed: 1977-12-07
Abstract: PURPOSE: To provide a cage of sight-seeing elevator, which is provided with a number of illumination lamps on the surface of its outer plating that can be flashed in a direction opposite to the motion of the cage, whereby it is enabled to amplify the motion of cage virtually.  
     CONSTITUTION: Illumination lamps 4 are provided on the surface of outer plating 3 of elevator cage 1 that is driven upward and downward along hoistway 5, and these lamps 4 are flashed in a direction opposite to the motion of cage 1. While the cage 1 is stopped, all of the lamps 4 are lighted. When the cage 1 begins to move upward, these lamps 4 are turned OFF successively from those located at the upper-most row on the outer plating 3 to the lower rows, through the cooperation of operation control system and flashing means. When the flashing position reaches the lowermost row, it returns again to the uppermort row. The above procedures are repeated while the cage continues to move upward. In contrast, when the cage 1 is moved downward, flashing position is shifted upward from the lowermost row. That is, flashing position is shifted in a direction opposite to the motion of the cage 1, so that speed of the cage 1 seems to be faster than the actual speed.

Title: Production of cold rolled steel sheet excellent in natural aging resistance and workability
Inventor: SUGIURA NATSUKO
IPC: C21D9/46
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To easily obtain a steel sheet having high natural aging resistance while its formability is secured by irradiating one side or both sides of surfaces of the steel sheet with a pulse laser without executing skinpass rolling after cold annealing. SOLUTION: In the case a condensed laser beam is irradiated on a steel sheet, irradiation, the steel sheet is rapidly heated almost simultaneously with the start of the laser, and, after the completion of the laser irradiation, the sheet is rapidly cooled down to an ordinary temp. By the local thermal shrinkage (expansion) of the steel sheet at this time, mechanical distortion is introduced therein. Moreover, by the laser irradiation, the base material of the steel sheet, coating material, atmospheric gas and liq. are made into plasma, and also by this plasma pressure, mechanical distortion is introduced into the steel sheet. When the laser irradiation is executed, only the surface layer is distorted, and distortion is not accumulated in the inside of the sheet.  Thus, dislocations are introduced into the surface layer to improve its natural aging resistance, but, the dislocations are not introduced into the inside, so that the high workability of the material is maintained. As the laser to be used, a Q switch laser based on a continuous wave CO2 laser is desirable.

Title: Resistance and capacity in highly stable high and low impedance at high frequency, and device for measuring their minute variation
Inventor: ICHIJIYOU BUNJIROU
IPC: G01R27/26
Filed: 1980-10-20
Abstract: PURPOSE:To eliminate zero drift due to temperature change in circuit parts by taking out a high frequency input voltage to a phase discriminator from a second turning circuit having the same circuit constants as those of a first turning circuit for measurement. CONSTITUTION:In a circuit A, the structure and the constants of the first and second circuits are completely the same, and the lengths of coaxial cables are also the same. The input voltage ex to the phase discriminator is induced in a coil which is electromagnetically coupled with l1 in the first circuit. The voltage ep is induced in a coil l2 which is electromagnetically coupled with l1' in the second circuit through a coupling capacitor CO2 from a tuning circuit comprising L2, C2V and R2. As a result, the phase drift of ep caused by the temperature change of the L2-C2V-R2 circuit becomes almost negligible. Since the constants of the first and second circuits are equal, the zero drift of a discriminator Igc due to the phase drifts of ex and ep caused by the temperature change can be completely eliminated.

Filed: 1978-11-29
Abstract: PURPOSE: To readily obtain stable performances of less losses by forming the same kind of wavelength-selective multilayer films on the respective surfaces of a square column of polygonal column transparent body.  
     CONSTITUTION: Respectively the same kind of wavelength-selective multilayer film 12 are deposited through vacuum deposition or the like on the surfaces BC, CD, DA of a polygonal column transparent body to form an optical branching filter 10. One length of light 13 including wavelengths λ 1 ...λ 4  is entered to the AB surface, allowing all these to transmit therethrough, thence it is entered at an angle θ 1  to the surface BC at the point P 1 . Only the wavelength λ 1  transmitting selectively through the point P 1  at the incident angle λ 1  is emitted to the outside and the remaining wavelengths reflect at the surface BC, thence they enter the face CD at an angle λ 2  at the point P 2 , allowing only the wavelength λ 2  to transmit therethrough and causing the wavelengths λ 3 , λ 4  to reflect toward the surface DA. Thereafter, the incidence and transmittance are repeated. Hence, if the incident angles are respectively vaired and the wavelengths are so selected as to transmit respective ly, the stable performances of less losses may be obtained by the use ofthe easy-to- manufacture optical branching filter.
