Title: Sludge treating apparatus utilizing waste heat
Inventor: TAN SEIICHI
IPC: F23G5/04
Filed: 1983-07-25
Abstract: PURPOSE:To perform treatment of sludge with high efficiency by providing a sludge heating kettle for evaporating water in waste gas, an air heater for exchanging heat provided between an incinerating furnace and a scrubber, oxidation tower for concentrated sludge, etc. CONSTITUTION:Concentrated sludge sucked up by a pump 69 from a sludge concentrating tank 67 and stored in a sludge receiver 70 is fed to a first heating kettle 33. The concentrated sludge introduced into an upper chamber 46 through a nozzle 48 is heated by the heat of condensation of steam in the waste gas while it flows downward through a pipe 49, and a part of water is vaporized and fed to a first mist separator 77 through a passage 75 in the form of steam. The liquid portion of the steam is fed to a passage 74 of the sludge through a passage 78 and the gaseous portion is fed to a heating chamber 34a of a second heating kettle 33a. The sludge which has been dried to some extent is fed to a chamber 46a of the second heating kettle 33a by a first stage pump 76.

Title: Scroll compressor
Inventor: KAJIWARA MIKIO
IPC: F04C18/02
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To improve the airtightness of a compression chamber while retaining the performance of a compressor, by applying gas pressure in a delivery chamber directly to a movable scroll so that the movable scroll is pushed to a fixed scroll side. SOLUTION: A movable scroll 11 is pushed to a fixed scroll 10 side in a manner that the upper surface of the end plate 11a of the movable scroll 11 receives pressure of high pressure refrigerant gas in a delivery chamber 22 through the opening 25a of a partitioning wall 25. Therefore, the end surfaces of the spiral bodies 10b, 11b of the fixed and movable scrolls 10, 11 are brought into contact with the end plates 11a, 10a of the counterpart side scrolls 11, 10, thereby a clearance among the end surfaces of the spiral bodies 10a, 11b and the end plates 11a, 10a can be eliminated. Thus, the airtightness of the whole compression chamber 14 can be retained.

Filed: 1989-05-29
Abstract: PURPOSE:To attain reproduction recording so as to send and receive a transmission message with high density during a short talking time by providing an operating speed control circuit controlling the variable operating speed of a recording and reproducing device. CONSTITUTION:A caller side sends a tone recognizing a transfer speed from a sound source transmission circuit 4 for a prescribed time before message transmission. When a tone signal reception circuit 8 detects a selection tone of a transmission speed at the caller side, it is reported to a recording/ reproduction control circuit 3a and the circuit 3a sends a control signal to an operating speed control circuit 51 to apply recording in matching with the transferred speed thereby preparing the operation of a recording and reproducing circuit 5a. Moreover, the circuit 4 sends a notice tone to communicate the transfer speed selection tone reception end to the caller side. When the caller side detects the notice tone at the circuit 8, it is reported by the circuit 3a, which sends a control signal to the circuit 51 to allow the circuit 5a to reproduce for message transmission thereby sending the message to a subscriber line.

IPC: G21C7/22
Filed: 1988-06-06
Abstract: PURPOSE:To flatten the axial output distribution of a pressure pipe type reactor by providing plural pieces of pipes which penetrate the core section of a fission type reactor in the vertical direction thereof to said core section and passing liquid contg. a neutron absorber in these pipes. CONSTITUTION:Gas 3 such as helium or carbon dioxide circulates on the outside of the pressure pipes and a heavy water reflector region 4 is provided around the core. A spacing is provided between the heavy water reflector and the pressure pipes and acts as an adiabatic region and as an outlet and inlet for the gas 3. The liquid control poison pies 5 penetrate the inside of the core in the perpendicular direction thereof and a poison soln. circulates therein. Since light water is heated by the heat of fuel rods while flowing from below to above in the pressure pipes 2, the temp. of the light water is higher toward the upper part so that boiling arises and the voids increase. The output distribution is, therefore, flattened if the poison pipes 5 are used, while a large output peak is generated in the lower part of the core if the poison pipes are not used.
