Title: Heat exchanger for oil combustor
Inventor: YAMAZAKI YOSHIAKI
IPC: F24H9/00
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To enhance corrosion resistance of heat exchanger and workability while protecting the environment and reducing cost by coating the inner wall surface of an inner shell and the surface of fins and heat receiving tubes with heat resistant and corrosion resistant paint. SOLUTION: The heat exchanger comprises a rectangular inner shell 10 made of plate material, and a plurality of straight heat receiving tubes 15 juxtaposed in the inner shell 10 with a large number of fins 12 being secured to the outer circumference thereof. The heat receiving tubes 15 are conducted, at the end parts thereof, through U-tubes 16 on the outside of the inner shell 10 and heat is exchanged when water from a water supply pipe flows through the heat receiving tubes 15. In place of conventional dipping treatment of lead, heat resistant and corrosion resistant paint is applied at least to the inner wall surface of the inner shell 10 and the surface of the fins 12 and the heat receiving tubes 15. Consequently, workability is enhanced in the corrosion resistance treatment of heat exchanger while reducing the cost.  Furthermore, environment can be protected because lead is not used.

Title: Core slider for magnetic head
Inventor: OKUYAMA SHINICHI
IPC: G11B5/60
Filed: 1988-07-22
Abstract: PURPOSE:To remove microcracks by joining a magnetic core made from ferrite and sliders, removing the unnecessary parts by machining and subjecting the surfaces of the core sliders to a smoothing treatment until a prescribed value is obtd. CONSTITUTION:The stock of the core sliders for the magnetic head is prepd. by weighing the oxides and carbonates of metals which are raw materials, for example, alpha-Fe2O3, MnO2, MnCO3, and ZnO to the molecular component ratios of ferrite, mechanically mixing these materials and heating the mixture at 1,000-1,300 deg.C. Plural pieces of test pieces are formed by machining this sintered ferrite and the sliders 3 to rectangular flat plate shapes of nearly the same size. The grain removal probability of ferrite decreases with a decrease in surface grain size and particularly the grain removal does not arise to Rmax=<=0.2mum when the plural test pieces which are different in the surface roughness are formed by lapping the above-mentioned test pieces. The microcracks are, therefore, removed by joining the magnetic core and the sliders 2, then smoothing the surfaces of the core sliders from which the unnecessary parts are removed by machining, to Rmax=<=0.2mum.

Filed: 1988-07-22
Abstract: PURPOSE:To invariably secure the proper engine rotating speed by stopping the output of an arithmetic means calculating the intake air quantity at the time of the no-load operation or parameters corresponding to it to a memory means with the output of a noncombustion detecting means. CONSTITUTION:When a sensor 8 outputs the value other than the full closure of a throttle valve 7, a control device 11 stops the rotating speed negative feedback control by an air quantity control valve 10 and calculates the intake air quantity of a bypass pipe 9 or parameters corresponding to it to allow the air quantity valve 10 to wait with the no-load intake air quantity opening. When the throttle valve 7 is fully closed and the negative feedback control conditions are satisfied, the opening of the control valve 10 is controlled so that the engine rotating speed detected by a sensor 4 becomes the desired value, the no-load intake air quantity at the desired rotation speed is stored in a RAM 103. When a noncombustion cylinder is detected by cylinder pressure sensors 13a-13d, the equivalent deficient air quantity is augmentatively fed to the other cylinders to supplement the deficient torque, the memory to the RAM 103 is stopped. The proper engine rotating speed can be invariably secured even if a noncombustion cylinder is generated.

Abstract: PURPOSE:To prevent a compression of liquid of a compressor in advance and to improve a reliability of the compressor by a method wherein an injection circuit of a two-stage compression refrigerating cycle is provided with a control valve which is closed when the compressor is started to operate and opened after a specified period of time elapses after the compressor is started to operate. CONSTITUTION:An injection circuit 10 is provided with a control valve 20 which is closed when a compressor is started to operate and opened after a specified period of time elapses after the compressor is started to operate. A control means for use in controlling its opening or closing time is provided with a timer 23 for use in counting an operation time of a compressor 4. As a two-stage compressor 4 is energized, an operation time (t) after energization is counted by the timer 23.
