Title: Manufacture of cast iron-made cylinder block
Inventor: TAKESHIGE NOBUHIDE
IPC: B22D27/04
Filed: 1989-10-25
Abstract: PURPOSE:To prevent lowering of wear resistance caused by structure change of a cylinder liner by feeding cooling gas into a bore core just before temp. of the cylinder liner reaches A1 transformation point after inserting the cylinder liner as internal chill to rapidly cool the cylinder liner. CONSTITUTION:In a sand mold 3 arranged with cavity 4 for pouring molten metal, the sand having coarse and good gas permeability is packed into a bore core 5 in the cylinder liner 2, and also a venting hole 6 communicated with the bore core 5 from lower part of the sand mold 3 is arranged. At the time of filling up molten metal 7 into the cavity 4 in the sand mold 3 by executing pouring of the molten metal under this condition, the cylinder liner 2 is inserted with cast iron as internal chill, and accompanying to this, temp. of the cylinder liner 2 is rapidly raised. Then, by feeding the cooling gas just before the temp. of cylinder liner 2 reaches A1 transformation point, the cooling gas reaches the inner circumferential face 2a of cylinder liner 2 from the venting hole 6 through inner part of the core bore 5 of coarse sand to rapidly cool the cylinder liner 2. Therefore, the pearlitic structure having high wear resistance is held.

IPC: G03G15/20
Filed: 1991-09-30
Abstract: PURPOSE:To prevent the leakage of the voltage of a fixing roller and an offset even if a fixing device is used for a long time by setting the most outside edge of the paper passing area of a recording form to the outside in an axial direction, compared with the most outside edge of the press-contact part region of a pressure roller and the fixing roller. CONSTITUTION:The pressure roller 2 is pressurized on the fixing roller 1 by a pressure means (not shown in this figure), to form a fixing nip. The contact area Z of a temperature detecting element 4 and the fixing roller 1 is set in a region where the contact area A is not directly in contact with the the pressure roller 2 when a sheet paper body 6 is in a nip, and the paper passing area is set so that the end part of the side of the contact area Z of the sheet paper body 6 protrudes from the nip. A protruding quantity DELTA1, is set to secure the creeping distance of the contact area Z and the end face of the pressure roller 2, when the elastic body 21 of the pressure roller 2 has conductivity. Thus, the paper sheet body 6 acts as an insulating body so that the bias voltage of the core metal 11 of the fixing roller 1 is not leaked.

Abstract: PURPOSE:To prevent overshoot in a thermostat by calculating a difference between a detection temperature in a gas absorption part in a sample storage part and that in a gas blowing part and setting the means value of both temperatures to be a setting temperature when the temperature reaches the prescribed temperature. CONSTITUTION:Temperature detection terminals A1-A3, B1 and B2 are respectively provided for the gas blowing part 51 and the gas absorption part 52. The detection terminal A1 is connected to a temperature controller 81 and a thermometer 82, the detection terminal A2 to a temperature over-rise prevention unit 83 and the detection terminal A3 to a temperature difference controller 84. If the setting temperature of the controller 81 is set to be 125 deg. and the difference of the gas absorption and gas blowing parts is defined as 2 deg.C, the setting temperature of the controller 84 comes to be 2 deg.C. When the difference of the temperature values which the detection terminals B2 and A3 detect comes to 2 deg.C, there is a relay output in the controller 84. Thus, the contact C of a circuit including the detection terminal B1 is closed and the means value of both is obtained from respective detection temperature of the detection terminals A1 and B1. Then, the temperature is controlled so that the mean value comes to the setting temperature 125 deg.C.

IPC: H05K3/46
Filed: 1990-10-17
Abstract: PURPOSE:To prevent cracks from occurring to the corners of a wiring and an insulating layer and to enable signals to propagate at a high speed by a method wherein conductor wiring layers and insulating layers are alternately laminated on an organic resin multilayer wiring board and an insulating layer interposed between the signal layer and the ground layer out of the laminated conductor wiring layers is formed of benzocyclobutane resin. CONSTITUTION:Conductor wiring layers such as ground layers 3a and 3b, signal wiring layers 4a and 4b, a power supply signal transfer layer 7, or an electric component mounting layer 8 and polyimide resin insulating layers 5a-5d are alternately laminated to form a polyimide resin multilayer wiring board where BCB resin insulating layers 6a and 6b are formed between the ground layers 3a and 3b and the signal wiring layers 4a and 4b. The insulating layers between the ground layers 3a and 3b and the signal wiring layers 4a and 4b are lower in permittivity than the polyimide resin insulating layer normal in permittivity, so that signals can be made to propagate at a high speed. As the BCB resin insulating layers 6a and 6b are formed only between the ground layers 3a and 3b and the signal wiring layers 4a and 4b, cracks can be prevented from occurring to the corners of a wiring or an insulating layer.
