Title: Petroleum boiler
Inventor: ANDO HIDEO
IPC: F24H1/26
Filed: 1985-05-07
Abstract: PURPOSE:To reduce and prevent generation of leakage in a heat exchanger, due to corrosion, by a method wherein an inner cylinder is protruded toward an outer cylinder side and is curled while the section of the inner cylinder, which contacts with the outer cylinder, is welded from outside to provide a burner inserting port at the side of the heat exchanger. CONSTITUTION:The inner cylinder 1 and the outer cylinder 2, both of which are made of stainless steel, are connected by upper and lower annular mirror plates 3, 3' and a water feeding port 4 as well as a hot-water supplying port 5 are connected to the upper annular mirror plate 3. The side surface of the inner cylinder 1 is protruded outwardly so as to have a cylindrical shape and the tip end thereof is curled while the section contacting with the outer cylinder 2 is welded from the outside of the heat exchanger to provide the burner inserting port 9 at the side of the heat exchanger. The burner inserting port 9 can be welded to the side surface of the outer cylinder 2, therefore, welding work is facilitated, the result of welding is stable, the manufacture of the burner inserting tube proper is unnecessitated and an effect to reduce the lengthes of the part and welding may be obtained. The heat capacity of protruding section 11, protruded toward hot-water side by projecting curl, is small compared with others, therefore, affection of heat due to welding becomes large and the section is easily corroded compared with the other free surfaces 12. Even when the wall is bored by corrosion, water will never be leaked since the corrosion prevention of other free surfaces may be effected by the protrusion 11 serving as an anode.

Title: Original reader
Inventor: AZUMA EIJI
IPC: H04N1/407
Filed: 1993-04-23
Abstract: PURPOSE:To obtain the original reader in which picture quality is not deteriorated even when a short read period is adopted to read an original at a high speed. CONSTITUTION:When a photoelectric conversion element 21 reads a picture to output an output voltage, an A/D converter 22 converts the output voltage into digital picture data. Then a read processing section 23 processes picture data from the A/D converter 22. Furthermore, plural gamma correction data are stored in a memory 27 and when the read speed of the original is revised by revising a read period of the photoelectric conversion element 21, gamma correction data are selected corresponding to the read speed. Then the read processing section 23 applies gamma correction to the data based on the selected gamma correction data. Thus, even when a read speed of the original is increased and the read period of the photoelectric conversion element 21 is short, the decreased output voltage is prevented and deterioration in the picture quality is prevented.

Title: Device cross call device
Inventor: NAKAMURA MASAYUKI
IPC: G06F13/14
Filed: 1982-06-09
Abstract: PURPOSE:To simplify the constitution of a titled device, by providing a memory within a device cross call device set between >=2 controllers and a device and opposite to the controller and then sending back a reserving or busy signal. CONSTITUTION:A device cross call device 3 is set between two controllers 1 and 2 which control a device 4. One of these two controllers, e.g., the controller 1 monopolizes the device 4. Therefore, if a reserving signal 5 is delivered, a reserving signal 6 gives a reply to the controller 1 with conditions 7 under which the device is not monopolized by the controller 2. At the same time, an FF13 is set to store that the device is monopolized by the controller 1. An AND circuit 20 is closed to set an output 11 to be delivered to the controller 2 at L. In this case, if the controller 2 supplies a reserving signal 8, a busy signal 9 is delivered in reply from an NAND gate 17. When the monopoly of the controller 1 is over, the FF13 is reset by a release signal 12. Then an access is possible for the controller 2.

IPC: G06F3/12
Filed: 1990-04-13
Abstract: PURPOSE:To obtain a video signal processing circuit of a small scale by using a reprogrammable logic element on the same circuit. CONSTITUTION:A reprogrammable logic element 4 which can be electrically programmed on a circuit is used to a picture memory control circuit which works when a video signal is fetched and the color print data is outputted. Then a gradation converter (threshold level A) is loaded into the element 4 from a programmable logic element program memory 6. Thus the gradation converter is actuated to convert the output of an A/D converter 3 and to write it into a picture memory 5. A threshold controller 2 decides the threshold levels B and C and written into the memory 5 after conversion when the conversion is over with all pictures. This operation is carried out for R, G and B respectively. Then the data on the memory 5 are converted into the print data and outputted. Thus the circuit scale can be reduced for a color hard copy device.

Title: Opening/closing valve
Inventor: MATSUNAGA SHIYOUICHI
IPC: F16K31/363
Filed: 1979-08-01
Abstract: PURPOSE: To secure valve operation regardless of leakage at the sliding surface of a pressure receiving piece in an opening/closing valve device in which the pressure in the flow-in chamber is to act on both sides of the pressure receiving piece, by providing a pressure relief valve in parallel with the flow control orifice.  
     CONSTITUTION: While valve 27 is closed, the pressure in a flow-in chamber 2 is introduced to both chambers 12a,12b of a pressure receiving piece housing 12 through No.1 pressure introducing hole 18 and No.2 pressure introducing passage 22 and there no pressure difference is produced, thereby closing of the valve 27 is conducted with the dynamic pressure in flow-in chamber 2 which acts on the back of the valve element 5. When the valve 27 is opened, the pressure in the flow-in chamber 2 is lowered by an orifice 23 and the pressure in the downstream chamber 12b becomes low, and thus the pressure receiving piece 16 is lifted up to open the valve. Because a check valve 25 equipped in parallel with the flow control orifice 24 opens at this time, the pressure in the chamber 12b will not rise up even through the sliding surface of the pressure receiving piece allows minor leakage. The valve element 5 can be thus operated securely.
