Title: Ventilation device
Inventor: HAGIWARA TADASHI
IPC: F24F7/007
Filed: 1987-02-20
Abstract: PURPOSE:To provide a ventilation device which substantially reduces the influence of the outside wind speed and does not adversely affect the ventilation fan for bath room or toilet by interlocking the ventilation fan and the air feed fan. CONSTITUTION:When a ventilation fan 2 disposed in a ventilation opening 3 is operated, an air feed fan 4 is disposed in an air feed opening 5 is also operated by an interlocking switch 6 connected to said ventilation fan 2.

Title: Acetylene gas sensor
Inventor: YAMAUCHI SHIRO
IPC: G01N27/42
Filed: 1985-03-01
Abstract: PURPOSE:To take out the amount of acetylene gas an an electric signal, by providing a metal ion conductive solid electrolyte comprising a metal selectively reacting acetylene, an anode comprising a platinum wire coated with a predetermined amount of the aforementioned metal and a cathode comprising a mixture of the aforementioned metal and the aforementioned solid electrolyte. CONSTITUTION:After a predetermined amount of gas to be inspected was introduced into a collection chamber through a polymer gas permeable membrane 4, opening and closing valves 3-1, 3-2 are closed and a switch 10 is turned ON. A known amount of copper is adhered to a copper deposited platinum anode 6 at first but, because of the rapid reaction with acetylene, the amount of copper proportional to the amount of acetylene changes to copper acetilide and the remainder of copper moves toward a cathode 8 through a copper ion conductive solid electrolyte 7 by constant current electrolysis to be precipitated on the cathode 8. Because the rising period of the terminal voltage between the anode 6 and the cathode 8 when there is no acetylene gas is preliminarily known, the amount of acetylene is immediately known from the difference of a rising time.

IPC: B61D17/18
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To easily and efficiently perform vibration damping material filling work into a hollow extruded structural angle in order to effectively prevent noise and vibration of a structural body traveling at high speed such as the Shinkansen. SOLUTION: An aluminum alloy extruded structural angle 1 is constituted of surface plates 2 and ribs 3 into a truss structure, and aluminum alloy partition plates 5 are engaged with engaging parts 4 and inserted in the longitudinal direction. Vibration damping materials 6 to be foamed by heating are attached in the specified position on both surfaces of the partition plates 5 in a not-foamed state by the specified amount. After these partition plates 5 are installed in the structural angle 1, the vibration damping materials 6 are foamed by being heated, and the hollow is filled in with the foamed vibration damping materials.  Therefore, the not-foamed vibration damping materials can be previously and precisely stuck in the specified positions of the partition plates in consideration of the state of after-foaming, the inner space can be completely filled with the foamed vibration damping materials, and sound insulation performance can be improved. The vibration damping materials can be installed in the shape only by inserting the partition plates, and vibration damping material filling work is simple and efficient. Moreover, the degree of freedom of design of the extruded shape is large.

Title: Exhaust emission control device for engine
Inventor: SAKASAI TAKASHI
IPC: F02D43/00
Filed: 1995-02-03
Abstract: PURPOSE: To keep the nitrogen oxide concentration within a specified value and also to keep the engine rotating speed constant by measuring the oxygen content and the nitrogen oxide concentration to calculate the nitrogen oxide concentration in a normal oxygen concentration to be controlled to a proper nitrogen oxide concentration. CONSTITUTION: An electronic control device 10 detects engine speed and the NOX concentration and O2 concentration in exhaust gas after an engine is started, and computes the NOX concentration in a normal O2 concentration according to the above data. It is judged whether the computed value of NOX is outside of the upper and lower limit values of a preset value or not, and if it is the preset upper limit value, the fuel injection timing is delayed. If it is the preset lower limit value, conversely the fuel injection timing is quickened. Even if the NOX concentration in exhaust gas of an engine is secured within a proper range, the injection timing is varied so that engine speed is outside of a normal range. If engine speed is the preset lower limit value, the injection quantity is automatically increased to increase engine speed.  If it is the preset upper limit value, the injection quantity is decreased.

Title: Production of cast roll for rolling
Inventor: HIRAOKA HISASHI
IPC: B22D18/02
Filed: 1982-03-12
Abstract: PURPOSE:To obtain a cast roll for rolling which is improved in abrasion resistance particularly by fining of the texture in the layer on the surface in the body part of the roll to be used for rolling in the stage of casting the roll, by passing a cooling medium in the hollow part in a metal mold and cooling the metallic mold quickly from the inside. CONSTITUTION:A metal mold which consists of copper or the like and is formed internally with a hollow part is prepared in the above-described casting. In the stage of casting a roll, a cooling medium such as water is passed in said hollow part to cool the metal mold from the inside quickly. An essential requirement in this case is to cool the molten metal quickly at 6-20mm./sec cooling rate. Such cooling rate for the molten metal is attained suitably by 3-5kg/cm<2> cooling water pressure and 100-1,000l/sec flow rate when water is used as the cooling medium. As a result, the molten metal is quickly cooled and solidified without the decrease in the life of the metallic mold, by which the solidified texture, more particularly the carbide formed in the stage of solidification is fined densely and the cast roll for rolling having high resistance to abrasion is obtained.
