Title: Ternary input method of electronic circuit
Inventor: ARAI NOBUHIRO
IPC: H03K19/20
Filed: 1984-06-15
Abstract: PURPOSE:To detect three states (H level, L level, OPEN) and to input the state by a single input/output terminal without using a lot of terminals by connecting a resistor and a capacitor between the input/output terminal of an electronic circuit and a point at a prescribed potential. CONSTITUTION:An FET3 is turned on for a period t0 before a potential at the input/ output terminal 2 is inputted, a capacitor 6 is charged up to a power supply voltage VDD regardless of the state of a switch (SW)5 and the potential at the terminal 2 is brought into an H level. When the FET3 is turned off, the potential at the terminal 2 remains H level when the SW5 is turned on to the position of contact A. When the SW5 is turned on to the position of contact B, the potential at a terminal 2 is decreased gradually according to the time constant comprising a resistor 7 and the capacitor 6 and when the SW5 is turned on to the position of contact C, since the time constant in this case is far smaller than the time constant when the SW5 is thrown to the position of contact B, the potential at the terminal 2 drops rapidly. After a t1 period, the potential at the terminal 2 goes to H level when the SW5 is turned on to the position of contact A or contact B, and goes to L level when the SW5 is turned on to the position of contact C. After a t2 period, the potential at the terminal 2 goes to H level with the SW5 turned on to the contact B and goes to L level with the SW5 turned on to the contact B.

Filed: 1984-06-15
Abstract: PURPOSE:To enable a resin pipe suitable as a piping material for ultrapure water to be produced, by extruding a thermoplastic resin pipe with the inner surface in a melted state, and cooling the inner surface while sliding it along an auxiliary mandrel having a smooth surface. CONSTITUTION:A resin pipe is extruded with the inner surface in a melted state caused by a heating apparatus provided to a mandrel near an extrusion port of an extrusion mold. The inner surface of the extruded resin pipe is cooled by sliding it along the auxiliary mandrel. Although it is preferable that the smoothness of the surface of the auxiliary mandrel is approximately in the same degree as required for the inner surface of the resin pipe, roughness of the surface of the mandrel may be on the order of 1.5-S. This is due to the fact that because the resin pipe is slid along the surface of the auxiliary mandrel to be smoothed, the roughness of the inner surface of the resin pipe is made to be a half of the roughness of the mandrel. The surface of the auxiliary mandrel is formed with a plurality of circumferential grooves that are communicated by zigzag grooves, a refrigerant is fed to the grooves, and when a negative pressure is applied, the resin pipe is cooled while it is slid along the auxiliary mandrel.

Filed: 1995-05-24
Abstract: PURPOSE: To take out a required amount of electricity without entering into overdischarging region by detecting the discharging depth of a battery and limiting the dischargeable current at a lower level as the discharging depth increases. CONSTITUTION: A control unit 92 reads in each load current and terminal voltage through a battery sensor 102 and determines the residual capacity of each battery 81a.
