Title: Cooling method for exhaust valve of diesel engine
Inventor: ENDOU HIROHISA
IPC: F02B75/02
Filed: 1979-08-09
Abstract: PURPOSE: To cool an exhaust valve securely by injecting a fixed quantity of cooling water in the back side of a valve seat during the period when both suction and exhaut valves are closed in a four-cycle diesel engine, while an exhaust valve is closed in a two-cycle diesel engine.  
     CONSTITUTION: A cooling water jetting nozzle 1 is set in the position inside an exhaust valve case 3 where the jetting and injection of cooling water in the back side of a valve seat 2 can be conducted. Water injection is conducted during the period when both suction and exhaust valves of four-cycle engine are closed and the exhaust valve of two-cycle engine is also closed. On the occasion, the quantity of water injected is set not to exceed the quantity which can be evaporated completely during the closure of the valves. Accordingly, the employment of such a means which is troublesome and liable to cause such an accident as water feeding to the movable part of the valves becomes unnecessary and because a direct cooling can be performed, the reliability of the device is increased to a large extent.

Title: Reflective road rivet
Inventor: SHIBA DAISUKE
IPC: E01F9/576
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to install and embed a road rivet with its surface flush with the surface of the road by providing a reflective ability element to one surface of a total reflection prism and providing these in an optical holding body. SOLUTION: A reflective ability element 2 by continuous shape of a corner cube prism is formed to a total reflection prism in one united body by a polycarbonate resin. These are provided in an optical holding device made of aluminum diecast. When using them, they are buried on a center line or a stop line on the road in such a manner that their surfaces become flush with the surface of road. By the optical effect, the total reflection prism 1 permits the reflective ability for the incident light from headlights from two directions on a roadway by introducing an incident angle where the reflective optical ability is effectively acting to the surface of the reflective ability element 2, nevertheless the incident angle is to the surface flush with the road surface.  Therefore, embedding and installation is possible to the surface flush with the road surface and therefore one factor of inducing traffic accidents, which was previously considered to be problematic in case of conventional raised reflection road rivets can be now eliminated.

Abstract: PURPOSE:To attain a satisfactory focusing characteristic and an amount of elimination even to the input signal of the reception side having intensive correlativity such as a sound signal, by using a means which reduces the correlativity of side input signal according to a self-recurrence model or adaptive estimation without increasing substantially the arithmetic amount. CONSTITUTION:An estimated coefficient calculator 26 regards an input signal of the reception side of the prescribed time length as the output signal of an M-degree self-recurrence model and obtains a linear estimating coefficient. An estimating device 27 uses the linear estimating coefficient and the input signal of the reception side to produce the estimated value of said input signal. A subtractor 28 subtracts the estimated value from the input signal of the reception side to obtain a difference signal of the input signal. A register 29 stores this difference signal. In the same way, an estimating device 30 produces the estimated value of output signal of the transmission side. Then a subtractor 31 produces a difference signal of said output signal. A corrector 32 uses the contents of a register 23 storing the estimated impulse reply of an echo path, the contents of the register 29 and the difference signal of the output signal of the transmission side to correct the contents of the register 23, then corrects successively the estimated impulse replies.

Abstract: PURPOSE: To set high-temp. gas to be treated at a working temp. and to execute efficient exhaust gas purification by increasing the concn. of catalysis-prompting metal oxide gradually from the peripheral edge part to the central axis of a support. CONSTITUTION: An catalytically active component, such as metal oxide for promoting a catalysis, is deposited on the inert ceramic or metallic support through which parallel flow passages flow. At this time, the concn. of the catalysis-prompting metal oxide is increased gradually from the peripheral edge 1 to the central axis 2 of the support. When the support is positioned in the active component of the catalyst in such a manner, the reaction initiation temp. of the high-temp. gas to be treated may be lowered by about 15 deg.C with respect to carbon monoxide and hydrocarbon and to about 40 to 50 deg.C with respect to NOx. Then, the effective exhaust gas treatment may be executed.
