Title: Method for preventing decarbonization of steel
Inventor: OMORI MASANAO
IPC: C21D1/70
Filed: 1988-03-19
Abstract: PURPOSE:To prevent change of the material quality caused by decarbonization on surface of a steel by applying the specific composition of decarbonizing prevention agent composing of SiO2 and Al2O3 as main component at the time of heating for hot-working the steel and heating. CONSTITUTION:Coated layer is formed by blowing solid-liquid mixing material having the following composition with a spray nozzle 4 at the lower face side while conveying the steel billet 1 with conveying roll 2. As the solid-liquid mixing material, water is added to the mixing fine powder having the composition composing of 10-30wt.% Al2O3, 5-15wt.% total of Na2O and K2O and the balance SiO2, and kneaded, to make the solid-liquid mixing material having 20-50wt.% water content. After drying this with a panel heater 5, the billet 1 is turned and at the process 6, the solid-liquid mixing material is applied on the side faces of the billet 1, and further at the process 7, the solid-liquid mixing material is applied on the surface of the billet 1 and dried to form the coated layer having 0.1-1.0mm thickness on the whole surface of the billet 1. This is charged in a heating furnace and by heating at <=1,170 deg.C, lowering of the strength caused by decarbonization on the surface of the billet is prevented.

Title: Continuous lining excavation method
Inventor: MIZUMOTO SADAO
IPC: E21D9/10
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To establish a tunnel excavating method, in particular for a mountain tunnel, which allows simultaneous execution of excavation and the lining without generating dust and causing a material loss when the internal wall surface of the tunnel undergoes a lining. SOLUTION: A tunnel excavating method for the facing 60 of a tunnel consists of; installing an air tube along the internal circumference of the excavated tunnel inside wall, encapsulating air in the air tube so as to form a concrete form, placing concrete between the concrete form of air tube and the tunnel inside wall, and lining its inside with concrete as the lining. The lining is performed at the same time as the excavating process for the facing 60 from the space formed inside the concrete form with the air tube, and the tunnel is achieved through continued cycles of these processes. This simplifies the cycle time of tunnel construction works to lead to cost-down of executing the works.

Title: Air conditioner
IPC: F25B1/00
Filed: 1992-03-24
Abstract: PURPOSE:To avoid actions of a protection device under overload conditions to expand the operating range of an air conditioner by providing a bypass pipe having a solenoid valve, which bypasses an outdoor heat exchanger and a depressurizing means to introduce refrigerant delivered from a compressor into said exchanger and controlling said solenoid valve. CONSTITUTION:In an air conditioner, during a cooling operation, the high temperature, high pressure refrigerant gas delivered from a compressor 1 is fed to an outdoor heat exchanger 3 via a four-way valve 2 so as to be heat-exchanged with the outside air. The pressure of the high pressure liquid refrigerant thus obtained is reduced at a depressurizing device 4 and said liquid refrigerant is sent to an indoor heat exchanger 5. And the indoor air is cooled by evaporating the liquid refrigerant and the liquid refrigerant having reduced pressure is flux to the compressor 1. In this case, a bypass line 7 is provided to interconnect the delivery side of the compressor 1 and a line 6 connecting the device 4 and the exchanger 5, and a solenoid valve 8 is disposed in the midway of the line 7. When the valve 8 is open, the amount of the refrigerant flowing through the exchanger 3 is reduced to prevent the conditioner from abnormally stopping under overload conditions.

CONSTITUTION:A drive floor is made to previously ascend, and the floor building frame 5 of a next upper floor N+1 is field-assembled on a just under regular provided floor 4. The lower part of a suspending tool 6 whose length L is obtained by adding the length of a spare length part L2 corresponding to the length of the floor building frame 5 to length L1 from the drive floor 1 to the floor building frame 5 is provided on the floor building frame 5.

Title: Controlling method of air-fuel ratio
Inventor: MANAKA TOSHIO
IPC: F02D41/02
Filed: 1980-05-21
Abstract: PURPOSE: To perform an optimum air-fuel ratio control of an engine by a method wherein actual measured values regarding the rpm of the engine and load data are compared to reference values to thereby determine a corrected duty of the engine and the corrected duty is further corrected in the power region of the engine by adding a predetermined value thereto.  
     CONSTITUTION: The actual values regarding the rpm of the engine, the negative sucking air pressure and the sucking air temperature are measured at Step 122 and the measured values are compared to prestored reference values so as to determine and then correct the duty of the engine at Steps 124 and 126. Then, when it is found by detection that the corrected duty is not for the power region of the engine, a control solenoid is controlled on the base of the corrected duty through steps 136 and 138. On the contrary, when the corrected duty is found to be for the power region, the secondary valve of a carburetor is inspected if it is opened or closed and when opened, a correcting values S is added to the corrected duty while when closed, a correcting value P is added to the corrected duty. The results such additions of the correcting values are transmitted to Step 136.

Filed: 1982-04-21
Abstract: PURPOSE:To promote a swirling action in cylinders of opposite ends, by arranging such that cylinders of opposite ends communicating with a suction port for a reduced load is inclined toward an outward direction of a cylinder row. CONSTITUTION:While an engine is operated at a reduced load, a suction port 7 communicating with cylinders A, B, C and D for an increased load is held as closed by an opening/closing valve 13. A suction port 6 communicating with intermediate cylinders A and D for a reduced load is arranged to have its inflow angle beta relative to a combustion chamber 3, formed as greater and more tangential than that alpha of suction port 6 communicating with cylinders A and D of opposite ends for a reduced load. Thus it is made possible for a swirling action in intermediate cylinders B and C to compensate for a difference in speed components even if a speed component directing outwardly of stream lines VB, VC at internal branch passages 25B, 25C is smaller than that taking place in the outward direction of stream lines VA, VD at external branch passages 25A, 25D.
