Title: Damping construction
Inventor: ISODA KAZUHIKO
IPC: E04H9/02
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To obtain excellent damping structure, installation and space utilization by jointing high clevises of high tension steel to both the ends of a damper portion of dead soft steel plate with the central portion narrowed and inserting it to a steel pipe and filling the gaps with a foamed material. SOLUTION: Clevises 10, 11 of high tension steel are jointed to both the ends 8b, 8c of a damper portion 8 formed to a smaller width than other portions at the central part 8a of a long-sized plate-shaped member of dead soft steel, and inserted to a steel pipe 9 and the gaps are filled with a hard foam material 13. The damping construction 3 produced as stated above is installed by jointing the clevises 10, 11 to the framing in a reverse V-shape. At the time of an earthquake, the dead soft steel damper portion 8 is yielded before the yield of the framing, thereby resulting in plastic deformation, absorbing vibration energy and damping the vibration response. A foamed material 13 in a steel pipe 9 presses the damper portion 8 uniformly, and restricts local buckling.  Also, the plastic deformation concentrates at the central part 8a where the width is narrow, and the yielding deformation decreases. Moreover, the damping construction has a light weight and thus at a low cost so that the space utilization of the building is not impaired.

Title: Digital-analog converter
Inventor: ITOU KENJI
IPC: H03M1/82
Filed: 1982-01-29
Abstract: PURPOSE:To accelerate the loop responsiveness, by comparing the contents of an M series shift register and those of a latch circuit and increasing the relative frequency of a PWM wave. CONSTITUTION:When the reference signal REF is supplied, the constant of a memory 31 is preset. Then the counting is started for clocks CP1. A latch circuit 33 latches the contents of a measuring counter 32 when a comparing signal COM is supplied. In the same way, a latch circuit 34 decides the upper 3 bits of the counter 32 as well as the contents of a carrier CRY and then holds the result of decision. The output pulse of comparison between the data of the circuit 33 and that of an M series shift counter 36 is converted into a direct current by an LPF38. If the center value of the circuit 33 is latched, a PWM wave of 50% duty is delivered with a 1-round frequency of the counter 36. The counter 36 averages the output and tuns it into an output of conversion corresponding to the center value. At the same time, the frequency of the output waveform of a comparator 35 becomes much higher than conventional with a small time constant of an LPF. Thus the loop responsiveness is improved.

Abstract: PURPOSE:To monitor a picture while the pickup operating state of a camera is not made remarkably without amazing a visitor by using a near infrared ray emitting element not causing reaction to human eyes as a light emitting element compensating the deficiency of a light source in using the titled camera as a night gate door monitor. CONSTITUTION:In using the titled camera as a day gate door monitor, an optical image is formed onto an image pickup face of a solid-state image pickup element 5 by an optical lens 2 through an optical filter 1 using a visible light region and part of a near infrared ray region as the pass band. Further, the light passes through a liquid crystal filter 4 before the image is formed onto the image pickup face of the element 5. The liquid crystal filter 4 adjusts the light quantity when the luminous quantity at daytime is too much. In using the titled camera as the night gate door monitor, the infrared ray element 3 is lighted in interlocking with the gate door chime of a visitor to compensate the luminous quantity for the night image pickup. The near infrared ray close to nearly 900nm lighted from the element 3 does not respond to the human eyes and passed through the optical filter 1 and the liquid crystal filter 4. The liquid crystal filter 4 reacts on the contrast of the visible light to adjust the luminous quantity but transmits the near infrared ray and no luminous quantity is adjusted.

Abstract: PROBLEM TO BE SOLVED: To provide a hydrogenating method and the device capable of more rapidly and efficiently treating a large quantity of a material to cause reaction compared to a hydrogenation method using conventional electrolytically generated hydrogen. SOLUTION: An electrolytic cell main body 1 is divided into an electrolytic section 3 and a hydrogenation section 4 by a cathode 2 made from a hydrogen occluding material and a porous hydrogen occluding body is installed in electrically contact with the cathode in the hydrogenation section.

Filed: 1988-01-23
Abstract: PURPOSE:To spread a gas under an active state to a wide space, and to form a film uniformly onto a wide film forming surface by activating a reactive gas by using cyclotron resonance. CONSTITUTION:Low-pressure mercury lamps 6 are employed as ultraviolet light source, and light having a wavelength of 185nm is radiated. Consequently, the excited state of a reactive gas excited can be continued. An inert gas or a non-product gas is used for cyclotron resonance. A product gas is employed as the reactive gas. These non-product gas is cyclotron-resonated and activated, and mixed with the product gas in a reaction space on the side outer than the resonance region, and excitation energy is transferred to the product gas. Consequently, the product gas receives extremely large electromagnetic energy, thus activating the product gas at approximately 100%. Ultraviolet light is applied from the reaction chamber, and the product gas is spread to the whole reaction chamber. A substrate is heated at a temperature of room temperature or 500 deg.C, thus shaping a film on a surface, on which the film is formed, in the substrate.
