Title: Burner nozzle for combustion of powdered coal
Inventor: HIRAYAMA AKIRA
IPC: F23D1/00
Filed: 1980-02-14
Abstract: PURPOSE: To decrease the concentration of generated NOX, by forming a region where the powdered coal burns with greater air ratio and the other region where it burns with lesser air ratio after jetting from a nozzle.  
     CONSTITUTION: A jet opening 1 for the powdered coal is divided into two parts by a partition plate 4-1 mounted in the center, and at the exit of the divided paths partition plates 4-2, 4-3 are mounted aslant to lead the jetted flow of the powdered coal aslant. A reverse aslant jetted flow of the powdered coal is made in a next lower stage by partition plates 5-1W5-3. Then a burner nozzle can produced divided flame to form a combustion region with a greater air ratio and one with a lesser air ratio and the value of NOX generated from each region is made smaller resulting in a smaller NOX value as a whole.

Title: Cmos buffer circuit
Inventor: KAWAMURA MASAHIKO
IPC: H03K19/00
Filed: 1984-02-02
Abstract: PURPOSE:To detect easily a high impedance state by connecting p-ch and n-ch transistors to an output terminal of a buffer part and exchanging each gate input with the input of said buffer part. CONSTITUTION:A p-ch transistor TR11 and an n-ch TR12 form a buffer, and a p-ch TR13 and an n-ch TR14 are connected in parallel to the TRs 11 and 12 respectively. The input of the TR12 is supplied to the gate of the TR13, and the input of the TR11 is supplied to the gate of the TR14. Thus an output 15 shows an intermediate potential when the buffer has a high impedance. Therefore a high impedance state can be easily detected by measuring the terminal potential from outside.

Filed: 1980-02-13
Abstract: PURPOSE: To prevent knocking and improve sufficient supercharging effect by driving a turbocharger with the exhaust pressure of the suspension side cylinders which cease operation in light loading.  
     CONSTITUTION: When an engine is operated in high loaded state, a shut-off valve 7 is open and a recirculating valve 6 is closed, and fuel is supplied to all cylinders #1W#6, and all cylinder operation is performed. The exhaust turbine 8 of a turbocharger 10 is driven by the exhaust pressure of the cylinders #4W#6. When the supply of fuel to the cylinders #4W#6 is intercepted in the light loaded state of the engine, the shut-off valve 7 is closed at the same time, and also air is cut, and the engine continues operation with only cylinders #1W#3. Then, the recirculating valve 6 is opened, and the air exhausted from the out-of-operation cylinders #4W #6 passes through a recirculation passage 5 and is recirculated to the intake side, and thus generation of pumping loss can be prevented.

Filed: 1978-02-15
Abstract: PURPOSE: To provide a chopper control device wherein when heat generated from a chopper has reached a set value, the period of interrupting the chopper is prevented from decreasing to a value less than the set value.  
     CONSTITUTION: When the conductivity of a chopper 6 is controlled by a hybrid control system by operating alternately an on-pulse oscillating circuit 2 and an on- pulse oscillating circuit 3 by the output of an accelerator circuit 1 of an electric motor car or the like, the detection of overheat of the chopper 6 is carried out by a thermostat 4b, and the base current of a transistor 2a of the on-pulse oscillator 2 is determined through a diode 1j by a potential operating at a point d of the accelerator circuit 1, thereby preventing the oscillation period from decreasing to a value less than the set value. For this reason, since the conductivity of the chopper is suppressed, and, at the same time, the maximum chopping frequency is lowered, it is possible to suppress loss at the time of commutation and to prevent overheating of the chopper.
