Title: Clear signal generating circuit
Inventor: YOSHIZAKI MAMORU
IPC: H03K19/003
Filed: 1979-07-24
Abstract: PURPOSE:To ensure the easy generation of the clear signals by connecting the diode and the Zener diode of the opposite polarity to the power supply voltage to the capacitor of the integral network which is connected between the power supply line and the ground. CONSTITUTION:With make of the power supply, the voltage of power supply line 1 is turned to voltage VCC at time T1 based on the power supply and the load. And charging voltage V1 of capacitor 3 starts rising up slowly than time T1 owing to existence of resistance 2. If the Zener voltage of Zener diode 5 is denoted as VD along with the base-emitter voltage of transistor 6 as VBE respectively, diode 5 does not conduct in the period of V1<VD+VBE with transistors 6 and 8 turned off and on respectively. Then the active low clear signals are delivered to clear logic circuit 9. After this, diode 5 conducts under V1>=VD+VBE, and the clear signal becomes high on the contrary to the above. And voltage V1 is turned fianlly into voltage VCC to become steady. In such way, the clear signals can be obtained easily and in a simple constitution of the circuit.

Title: Biaxially oriented polyester film
Inventor: UCHIUMI SHIGEO
IPC: B29L7/00
Filed: 1988-04-19
Abstract: PURPOSE:To obtain a biaxially oriented polyester film having little curling by a method wherein the specified physical properties are given to the film concerned. CONSTITUTION:The biaxially oriented polyester film concerned satisfies the formulae 1-4 simultaneously. In DELTAP is below 16.22-10.n of below 0.155, the orientation of the amorphous layer of the film is low, resulting in facilitating the permeation of solvent and making the degree of curl layer. If DELTAP exceeds 0.180, the contraction rate of the film is too large to be used. If (n) is below 1.6050 or 1.622-0.1.DELTAP, the amorphous layer of the film increases, resulting in facilitating the permeation of solvent and the generation of curl. If (n) exceeds 1.6085, the strength of the film lowers. If alphaMD+TD exceeds 3.0%, the degree of curl deteriorates, even when DELTAP and (n) are within the predetermined range. Further, the intrinsic-viscosity member [eta] of the film preferably satisfies 0.55<=[eta]<=0.75. If said intrinsic-viscosity number [eta] is lower than 0.55, the difference between the degree of crystallization at the front of the film and that at its back tends to develop and consequently curl tends to generate, when only one side of the film is immersed in solvent. If said intrinsic-viscosity number [eta]exceeds 0.75, the degree of crystallization of the film becomes difficult to enhance.
