Title: Oscillation circuit
Inventor: WADA MASAHIKO
IPC: H03K19/096
Filed: 1985-01-09
Abstract: PURPOSE:To save the electric power consumption of a system by providing two systems of output terminals, a means stopping the clock output and a means releasing the stop to a clock output so as to utilize effectively the two systems of output terminals. CONSTITUTION:When power is applied, an initial state setting circuit 6 initializes a selection circuit 3 and a release circuit 5, a basic oscillation circuit 1 oscillates a clock and output signals O1, O2 in phase are outputted from an output circuit 2. When input signals I1, I2 are inputted to an inhibition circuit 4 so as to stop the clock output of the signal O2 while the signal O2 is outputted, the circuit 3 is activated to stop the output of the signal O2 from the circuit 2. When a signal I3 is inputted in this state, the circuit 5 transmits a signal releasing the output stop of the signal O2 to the circuit 4. Thus, the circuit 4 resets the circuit 3 to restart the output of the signal O2. The signal O2 is stopped or restarted synchronously with the trailing and leading of the signal O2. The power consumption is reduced by utilizing effectively the signals O1, O2 in response to the state of system.

Title: Fusion cutter for fusible seal
Inventor: YOSHIDA YOSHINORI
IPC: B29C65/00
Filed: 1991-01-16
Abstract: PURPOSE:To lessen the amount of resin attachment at the time of fusion cutting, by coating fine grains of NiCr alloy having specified grain sizes with a Si type oil, spraying it to the surface of a fusion cutter made of metal, and forming a coating layer. CONSTITUTION:Two hot melting sheets, for example non-woven cloth 1, are placed one over the other, transported by a belt conveyor 2, and cut by a heated fusion cutter 3 of metal, which moves up and down in the cutting position. The cut laminate is sealed and sacked, when the molten resin tends to attach to the fusion cutter 3. When the amount of resin attachment becomes too much, fusion of the cut part becomes imperfect to require removal of the attached resin 4. Therefore, fine grains of NiCr alloy having grains sizes Rmax 40-80mum are coated with Si type oil, and this is sprayed and applied to the surface of the fusion cutter 3 so as to form a coating layer of 100mum thick. Thereby the molten resin will not attach easily, and frequency of resin removing works can be decreased.
