Title: Tunnel exhaust gas disposing method
Inventor: CHIBA KIYOSHI
IPC: E21F1/00
Filed: 1989-04-17
Abstract: PURPOSE:To facilitate operation and management for disposal of exhaust gas by a method wherein an electric dust collector is disposed as a device at a stage followed by an exhaust gas disposing device and an adsorbent layer is formed at a stage preceded by the disposing device to adsorb SO2 and NO2. CONSTITUTION:Exhaust gas disposing devices 61-64 are provided with an electric collector P and an adsorbent A to adsorb and remove SO2, aldehyde, NO2, and effective disposal of exhaust gas is effected in a way that filters are combined together in a 2-stage. An airflow sensor and an NOX sensor are mounted to the terminal of a main duct 11, and an airflow and NOX concentration are measured by means of an airflow meter W and an NOX densitometer N1. Information is inputted to a computer C1 for computation and a result is transmitted to an indicator D. When information from the indicator D is below the environment reference value of an NOX amount, blowers 21-24 are brought into an OFF-state, devices 61-64 are stopped, and control is effected so as to pass exhaust gas through bypass pipes 51-54. This method reduces an operation cost.

Title: Power supply
Inventor: YAMANAKA YUKIO
IPC: H05B41/24
Filed: 1989-04-14
Abstract: PURPOSE:To enable obtaining DC voltage with a small quantity of ripple by connecting the series circuit of first and second impedance elements causing DC to flow with AC power supply and by connecting controller smoothing capacitors between DC output terminals of the connection of said both impedance elements and a diode bridge. CONSTITUTION:Controller smoothing capacitors C1 are connected with one side of the common cathode of two diodes connecting the connection of first and second impedance elements Z1, Z2 and the cathode of a diode bridge DB1 respectively with both ends of an AC power supply AC. Therefore, when said power supply AC is turned ON, a charging current flows always in the same direction from the power supply AC to said smoothing capacitors C1. When the power supply AC is interrupted, said smoothing capacitors C1 are separated from a smoothing capacitors C2 for a central apparatus by the remaining two diodes and electric charge is hindered from flowing from the smoothing capacitor C2 into the smoothing capacitors C1.

Abstract: PURPOSE:To increase the adhesive strength of plating metal and to facilitate the preparation of a mold by forming a taper surface facing the upper half part of a mold body by shaving the inside of the lower half part and by providing a metal plating layer after activation. CONSTITUTION:The inside of the lower half of a mold body 1 is shaved to form a lower-half internal wall surface 3B and a taper surface 3C outside an upper-half internal wall surface 3A, and they are smoothed, degreased and washed. After the upper-half internal wall surface 3A is covered with a tape 7, the lower-half internal wall surface 3B and the taper surface 3C are activated with a mixed solution of sulfuric acid and hydrogen peroxide.

IPC: G11B7/09
Filed: 1979-07-25
Abstract: PURPOSE: To allow accurate focusing with a small size by periodically changing the driving current of a semiconductor laser between fixed DC levels.  
     CONSTITUTION: In addition to the constitution of a known automatic focusing device, this device is so designed as to periodically change the driving current of a semiconductor laser 1 between fixed current levels. To this extent an AC circuit 14 is inserted in its circuit and since this eliminates the fluctuations of phase detecting output owing to the interference effect of laser light, focusing is accomplished accurately based on said phase detecting output. In addition, the miniaturization of the device may be achieved by making the optical path length L between the semiconductor laser 1 and the target 5 sufficiently short within a coherent distance.

Title: Propelling device utilizing centrifugal force generated by amplitude of deviated portion of container
Inventor: AOKI SHIRO
IPC: F03G3/00
Filed: 1985-05-07
Abstract: PURPOSE:To decelerate one of reciprocating strokes of a container generated obliquely upward and downward with resistance on water surface to provide a rectilinear force with the reaction by rotating a rotary disk obliquely rather than horizontally in a container which disk has a weight such that it is inclined in one way. CONSTITUTION:When a container 1 is floated on the water and a rotary disk 5 is rotated right or left, the rotary disk having a weight 6 attached thereto begins to rotate while oscillating and drawing a circle, since a weight 6 is attached to the rotary disk. And in the rotation of the weight 6, the container 1 tends to be propelled right ward a length of distance A on the water by the reaction of the weight 6. However, since the rotary disk 5 is mounted inclined right downward, a portion of propelling motion receives the resistance of the water so that the propelling distance is somewhat shortened by the reaction. When the rotary disk 5 is further rotated and returned to the original position, the container 1 tends to be propelled leftward by the reaction of the weight 6. In this case, however, the container 1 is propelled leftward without receiving the resistance of the water surface.
