Title: Control method for desulfrization of gas
Inventor: KUMAGAI MASATOSHI
IPC: B01D53/34
Filed: 1987-02-18
Abstract: PURPOSE:To improve the conversion rate of S, by measuring the electric poten tial of oxidation and reduction of liquid absorbent at the outlet of a regeneration tower of used liquid absorbent, and controlling the amount of the air blown into the regeneration tower so that said potential is in -120--150mV. CONSTITUTION:Undersulfurized coke oven gas is introduced to an absorption tower 11 and is brought into contact with the absorbent containing catalyst, such as naphtoquinone ammonium sulfonate, to absorb and remove H2S, and the absorbent is sent to the regeneration tower 12, and air is blown in to form S. In this case, the potential of oxidation and reduction of liquid absorbent is measured by an oxidation and reduction potentiometer 14, and the detected value is sent to a flow rate control valve of an air supply pipe 15 to control the amount of air so that the oxidation and reduction potential is in -120-150mV. Thus, the conversion rate of S is improved.

IPC: E01F9/00
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To increase flexural rigidity by internally providing a plurality of projections on the internal surface of a pole as integral part thereof along the lengthwise direction of the pole, and applying specific dimensions to the pole and projections. SOLUTION: A sight line guidance road-sign pole is formed out of a thermoplastic elastomer cylindrical pole 10 with projections 11 formed on the internal surface thereof over entire length as integral thereof, a cap 20 and a base 30. Each projection 11 has a cross section of nearly semicircular cylinder or the like, and arranged at equal angular intervals around a center axis. Also, the pole 10 has height between 650 and 800mm, an outer diameter between 40 and 150mm and thickness equal to or more than a value between 1 and 5mm. The angular intervals between the projections 11 are 120 degrees or 90 degrees. At the time of erection on the road, the base 30 is assembled with the lower end of the pole 10 and a screw member 14 attached to the lower end of the pole 10 is screwed to the screw hole 41 of a leg member buried in the road.  The pole 10, upon contact with an automobile, bends to release a shock and is then elastically restored to an original form. Thus, the second moment of inertia becomes large and flexural rigidly increases, thereby enabling the pole 10 to be made long for better visibility and to be properly restored.

The foam plate is divided into two foam plates having equal thickness or divided into two foam plates different in thickness. These two foam plates are bonded back to back by an adhesive. In other words, the surfaces having the skins 1 of the foam plates are mutually opposed to be bonded by the adhesive. As the adhesive, a copolymer having a softening point lower than that of the styrenic resin, for example, a vinyl acetate/ethylene copolymer is pref. The adhesive film composed of the copolymer is held between the foam plates to be pressed to bond the foam plates.

Title: Regenerating brake controller for electric motor vehicle
Inventor: OSADA KINICHI
IPC: H02P3/14
Filed: 1978-03-27
Abstract: PURPOSE: To improve the safety of a regenerating brake controller for an electric motor vehicle by breaking both a regenerating brake and a breaker when passing a no-voltage section.  
     CONSTITUTION: Relay contacts RY2-B and RY2-A are connected to the control circuit of a current limiter solenoid valve CLV. When the coil RY2-C of the relay RY2 is energized and the contact RY2-A is closed, a current limiter LC and a breaker LB continue closing even if an electric motor vehicle is idling. When a regenerating brake switch contact S5 is opened, the coil RY2-C of the relay RY2 is deenergized. When a main controller main handle is shifted to OFF position, the current limiter CL and breaker LB are opened. Since the breaker LB is opened at this time, the regenerating brake is not operated even if the handle is shifted to a normal brake position and a contact S7 is closed to apply brake command to a field regulator controller FRG.
