Abstract: PURPOSE:To produce an Al alloy sheet excellent in formability and baking hardenability by interposing an intermediate heat treatment stage between hot rolling and cold rolling stages and performing crystalline grain control, at the time of producing an Al-Mg-Si alloy sheet. CONSTITUTION:An ingot of an Al-Mg-Si alloy, which has a composition containing, by weight, 0.3-1.0% Mg and 0.5-2.0% Si so that Mg/Si is regulated to <=1 and further containing 0.05-1.0% Mn and <0.5% Fe, is heated to a temp. not higher than burning temp. and subjected to homogenizing heat treatment. The ingot is hot rolled without delay. The resulting plate is subjected to intermediate heat treatment consisting of holding in the as-hot-rolled state at >=300 deg.C/min heating rate at 450-520 deg.C for 0-10sec and then cold rolled at >45% draft into a sheet. Subsequently, the sheet is rapidly heated to 500-580 deg.C at >=300 deg.C/min heating rate, held at the above temp. for >=10sec, cooled rapidly without delay, and further held, as final heat treatment, at 50-120 deg.C for 1-48hr. By this method, the Al alloy sheet, in which average crystalline grain size and coefficient of variation of crystalline grain size are regulated to <30mum and <0.38, respectively, and which has superior characteristics, can be obtained.

Abstract: PURPOSE:To provide a thermoelectric voltage conversion circuit capable of converting a voltage even if a polarity of the output voltage of a thermoelectric element is reversed. CONSTITUTION:A polarity matching circuit 3 comprising diodes D1 to D4 is installed between a thermoelectric element 2 and a step-up circuit 4. By providing this matching circuit 3, when one output terminal P1 of the thermoelectric element 2 is a positive voltage, a generating current flows in order of the diode D1, a step-up coil L1, a transistor Q1, the diode D4 and the other output terminal P2, and a positive voltage is generated in an output terminal P5 and a negative voltage is generated in an output terminal P6. On the other hand, when the output terminal P2 is the positive voltage, the generating current flows in order of D3, L1, Q1, D2 and P1, and similarly, the positive voltage is generated in P5 and the negative voltage is generated in P6. Thus, the degree of freedom of a mounting place of the thermoelectric element 2 is improved since the output voltage from P5 and P6 is picked even if a polarity of P1 and P2 is reversed.

Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To provide duplicate transmission control, such as decision of an active system/a standby system and system changeover on the occurrence of faults without intervention of application on a controller. SOLUTION: The identical address is decide for duplicate control devices 2A, 2B and an identification number that can definitely identify each control device is decided, and an identification number of its own device and an opposite device is stored in the control devices 2A, 2B.

Furthermore, when a control device acts as an active system and receives the frame from the other control device, the control device sends a check frame to the network as a response.  When a control device receives a transmission response before becoming the active system and when the response includes an identification of the responded control device in pairs with the control device, the control device acts as a standby system, and when the response does not include the identification number, no transmission control is conducted afterwards.
