Title: Pretreatment of joining sintered material and engine cylinder head structure
Inventor: ADACHI SHUHEI
IPC: B23K11/34
Filed: 1992-04-08
Abstract: PURPOSE:To pretreat a sintered material to enhance its joining property, to join a valve seat to the peripheries of the sintered suction and exhaust ports of a cylinder head for the multi-valve engine without cracking the head and to provide a cylinder head structure. CONSTITUTION:The void 3 of a sintered material 1 is filled by infiltration with a metal 4 such as Cu and Al having high electric conductivity and capable of easily impregnating the material 1 (pretreatment for joining). Since the conductivity of the entire material 1 is enhanced in this way, the heat evolution in the material 1 is reduced, more heat is locally released at the joining interface, and hence the material 1 is joined to another member. Accordingly, when the pretreatment is applied to a valve seat consisting of the sintered material, the valve seat is welded as such to the cylinder head, and the cylinder head having a short inter-port distance is not cracked.

Title: Combustion equipment for pulverized fuel
Inventor: SEKIGUCHI YOSHITOSHI
IPC: F23C99/00
Filed: 1980-08-19
Abstract: PURPOSE: To quickly gasify secondary fuel by decomposition and effectively reduce NOX by a method wherein the fine and coarse powders of the pulverized fuel are individually used as the secondary and primary fuels.  
     CONSTITUTION: The pulverized fuel is classified into the fine powder and the coarse powder sent respectively to a secondary fuel nozzle 4 and a primary fuel nozzle 2 by means of blowers 9 and 7. At first, the primary combustion is performed between the primary fuel consisting of the coarse powder and the primary air in the low air fuel ratio by supplying the amunt of the primary air of about 0.3 times as much as the amount of air necessary for the combustion of the whole fuel. After that, the secondary fuel consisting of the fine powder is supplied from the secondary fuel nozzle 4 in more amunt than necessary for consuming the oxygen remaining in the exhaust gas of the primary combustion to put the secondary combustion zone in reducing atmosphere. As a result, NOX generated wthin the primary combustion zone is reduced to N 2  in the secondary combustion zone. After that, the tertiary combustio is performed by supplying the secondary air from a nozzle.

Abstract: PURPOSE:To suppress the inverting phenomena caused by the variance of an FM modulation signal at reproduction as well as the deterioration and variance in the S/N and frequency characteristics by detecting the inverting phenomenon of a video signal undergone the FM demodulation and feeding back this detection output. CONSTITUTION:One of FM-demodulated videos signals which are reproduced out of a magnetic tape 18 by a video head 1 and received via an AGC circuit is outputted as a reproduced video signal via a noise cancel(NC) circuit 10 and a picture control circuit 11. At the same time, another one of FM- demodulated video signals is demodulated by a 2nd FM modulator 14 and inputted to an inverting phenomenon detecting circuit 17 via a 2nd de-emphasis circuit 15 and a 2nd LPF 16. Both horizontal and vertical synchronizing signals are deleted out of the video signal via the circuit 17 and therefore only the pulse produced by the inverting phenomenon is taken out. This pulse is converted into a DC and this conversion output is fed back to a 1st equalizer circuit 5, the circuit 10, and the circuit 11 respectively. Thus it is possible to suppress the inverting phenomena as well as the deterioration and variance in the S/N and frequency characteristics.

In this case, a pressure opening/closing solenoid valve 7 is opened, and a pressure opening/ closing valve 4 opens due to remaining pressure of the pressure tank 9. Then, when the pressure tank 9 is fully filled with water and the water reaches to an electrode 13, a high-pressure automatic opening/closing solenoid valves 18, 19 open. And the pressure solenoid opening/closing valve 7 and the pressure opening/closing valve 4 close respectively due to pressure increase in the pressure tank 9, so that water within the pressure tank 9 is discharged. On the other hand, when the draining finishes, a water-feed automatic operation circuit 21 is operated, and thus the pressure opening/ closing solenoid valve 7 and the pressure opening/closing valve 4 open respectively and water feed is started.

Abstract: PURPOSE: To prevent a printing of an original black side when a both side original is read and to improve the density of the surface of an original to be read and the thinness of an image by automatically lowering threshold by lowering a white level and reflecting the density of the original to be read on the threshold. CONSTITUTION: A pressing member cover 13 is opened and an original S is placed on an original platen 12. In this state, the back face of the original S is pressed by a pressing member 11 and the member 11 is adhered to the back face of the original S. By the depression of the start button 7 within an operation part 6, the moving of an image reading part 4 by a reading control part 1 is started. The reading part 4 converts the reflected light on an original surface into an analog image signal and outputs the signal. The signal is stored in a RAM 3 via an A/D converter 5. A threshold determination part 2 setes the maximum value and the minimum value of the stored data within the RAM 3. The determination part 2 determines threshold C as the average value of white and black levels. The picture element data within the RAM 3 is binarized.  The subsequent picture element information is also binarized based on the threshold C. When the threshold is corrected according to the white and black levels, subsequently, the threshold is binarized, the reading is terminated, the processing is terminated.

Filed: 1988-05-12
Abstract: PURPOSE:To shorten a waiting time which is until copying actions are started by detecting that the cover of an original platen is opened and shifting from an energy saving mode to a temperature regulating mode with a detection signal. CONSTITUTION:When a user opens the cover 7 of the original platen in order to set an original on the original platen 9, an original platen cover detector 6 detects the effect and a microprocessor 2 starts to energize a heating device 4, when the mode is shifted from the energy saving mode to the temperature regulating mode. When the user sets the original, closes the cover 7 and depresses a copying start key 1, the devices necessary for copying actions such as a motor and solenoid display unit 5, etc., are controlled by the processor 2 to start the copying actions. Since the device 4 is started to be energized and the mode is shifted to the temperature regulating mode at the time of opening the cover 7, the waiting time which is from depressing the key 1 until starting the copying actions can be shortened.
