Title: Printer
Inventor: KITAGAWA KUNIO
IPC: B41J11/66
Filed: 1989-06-26
Abstract: PURPOSE:To prevent occurrence of line feed misalignment by providing a device to prevent the forward fall of paper including a movable window supported by a bracket on the top of a cutter blade surface of a cutter mechanism and returning the window to a home position by a spring after operation. CONSTITUTION:Paper 2 printed at a printing mechanical section 1 passes through an area between a cutter 5 and a paper guide 6 after running between a feed roller 3 and a tension roller 4, then is sent directly to a window 7. The paper 2 which hits the window 7 is sent to the rear of a printer. When the paper 2 is cut, the window 7 returns to a home position by the elasticity of a torsion spring 11 after the rotational movement of bracket 10 with a shaft 9 installed at the fulcrum of a support bracket 8 as a center and the subsequent separation of the paper 2 from the window 7. Thus the paper is cut and the constant feed of the paper after passage through the blade surface of a cutter is ensured. For this reason, the folding of the paper can be improved and the occurrence of line feed misalignment can be prevented.

Filed: 1980-11-25
Abstract: PURPOSE:To obtain a desired threshold voltage in the insulated gate type semiconductor integrated circuit device by connecting two insulated gate type FETs in series with one another on one Si substrate and controlling the characteristics of the second FET by the voltage applied to the second insulating gate. CONSTITUTION:The insulated gate type FETT2 having a floating gate G3 connected in series with the insulated gate FETT1 of predetermined structure is formed on an N type Si substrate 11. When large reverse voltage is applied to the drain D2 of the element T2 and the substrate, charge storage occurs at the gate G3, and the amount of the charge can be controlled by the reverse voltage. It can also be reduced in proportion to the applied voltage to the gate G2 after the storage. Thus, the channel conductivity under the insulating gate can be varied, thereby controlling the threshold voltage of the element T2. Thus, the threshold voltage of the element T1 is controlled by the charge storage amount to the floating gate G2 of the element T2, the threshold voltage of the element T1 can be varied to a desired value, the stored charge is reduced as high resistance of high integrity, and can be associated with an LSI.

Title: Sample & hold circuit
Inventor: OKAMOTO MASAMI
IPC: G11C27/02
Filed: 1993-06-10
Abstract: PURPOSE:To prevent erroneous function even when a pulse signal inputted to be sampled has a narrow pulse width. CONSTITUTION:When a pulse signal Va to be measured has a voltage level higher than a reference voltage Vb, a comparator 1 outputs a pulse detection signal (c). A delay circuit 5 delays the pulse detection signal (c) by a predetermined time in order to delay the sampling timing by an amount corresponding to the rising time of the pulse signal Va and the delayed signal is inputted to a sampling pulse generating circuit 6. The sampling pulse generating circuit 6 generates a sampling pulse (e) having a predetermined pulse width in response to the rising of the delayed pulse detection signal (d). Since an AND circuit 7 delivers an AND output (f) only when the pulse detection (c) is active, the sampling is not effected at a moment of no signal.
