Title: Thermal deformation restraint method at processing point in composite-structured machine tool
Inventor: TANABE IKUO
IPC: B23Q1/01
Filed: 1992-09-03
Abstract: PURPOSE:To restrain relative dimensional-change between a tool and a work caused by thermal deformation due to change in boundary conditions such as processing conditions and room temperature fluctuation, in a composite-structured machine tool comprising its main composition parts such as a bed and a column made of materials having low heat conductivity and low temperature conductivity such as concrete, and comprising a headstock and a tool rest made of metal. CONSTITUTION:Main composition parts such as a bed 1 and a column are made of concrete, a headstock 3 and a tool rest 2 are made of metal, and a heater 4 is mounted on the tool rest 2. During processing, the headstock 3 is thermal deformed upward due to heat generation of a main spindle bearing so that a work 6 and a tool 5 on the tool rest 2 are relatively displaced. Therefore after the relative displacement is measured by a sensor and relative displacement quantity is calculated, the heater 4 is operated so as to heat the tool rest 2. The tool rest 2 is thermally deformed upward by heating and at the same time the tip part of the tool 5 is thermal deformed in the central direction of the main spindle so that, judging from a relative viewpoint, the thermal deformation of the headstock is cancelled in due course.

Title: Protecting system for regenerative power absorbing device
Inventor: YOSHIKAWA HARUKI
IPC: H02J3/28
Filed: 1986-11-06
Abstract: PURPOSE:To prevent overheat in a DC electric car, by judging an occurrence of a failure when a voltage adjusting means delivers a current intermittent operation signal although the voltage across a capacitor is lower than a predeter mined value, so as to stop regenerative operation. CONSTITUTION:During regenerative operation of an electric car, when the voltage Vc of a capacitor is raised from a set value set on a setting unit 36 due to regenerative current from a feeder line 4, a voltage adjuster 34 delivers a signal to a phase shifter 35 to intermittently turn on a chopper 33 in order to allow a load resistor 32 to consume power. In this stage, when the voltage adjuster 34 continue to transmit an intermittent signal from the chopper 33 to the phase shifter 35 although the input voltage Vc is lower than a set value set on a low voltage setting unit 50, an abnormality detecting circuit 40 judges that the voltage adjuster 34 fails, and stops the operation of the chopper 33 through the phase shift 34 so as to prevent the load resistor 32 from being burnt. Thus, there is no risk of useless power consumption, and further it is possible to avoid the overheat and burning of a resistor, and as well to a risk of fire.
