Abstract: According to one embodiment, An electronic apparatus includes a main body, a display unit and a hinge portion. The main body includes a first convex and a second convex disposed on an upper face of the main body. The display unit includes a leg portion having a projection. The hinge portion joints the main body and the display unit. The hinge portion includes a rotation shaft rotatably supporting the display unit between a closed state and an open state and a pivot shaft swingably supporting the display unit between an obverse state and a reverse state. The projection is engaged with the first convex when the display unit is in the obverse state, and engaged with the second convex when the display unit is in the reverse state.

Abstract: A precision voltage reference circuit which includes a pair of similar flash EEPROM memory cells, each of the pair of similar flash EEPROM memory cells having a different charge on its floating gate; circuitry for connecting each of said cells in a pair of parallel circuits in which equal current values are generated in an equilibrium condition; apparatus for sensing a voltage in each of said pair of parallel circuits to provide an output voltage which may be used as a reference value when the currents are in equilibrium; and apparatus for sensing variations in the output voltage to vary the current through the flash EEPROM memory cells to bring the currents into equilibrium when the reference voltage varies from the voltage provided at equilibrium.

Abstract: A die casting machine in which a rotary table, mounted with a plurality of die open and close units each holding a die, is sequentially brought into association with a plurality of work stations. The die is clamped in two steps, that is, a regular die clamping and a temporary die clamping. The regular die clamping is carried out by applying the regular clamping force required by a particular injection step. The temporary die clamping is carried out by applying a clamping force which is smaller than the regular clamping force. Consequently, this die casting machine can greatly reduce the time required for the casting cycle for each product, thus providing remarkably improved productivity. Preferably, a metal cooling apparatus suitable for a rotary die casting machine may be further provided.
