Title: Manufacture of semiconductor storage device
Inventor: TANAKA NOBUYUKI
IPC: H01L27/108
Filed: 1993-02-24
Abstract: PURPOSE:To improve the withstand voltage of the capacity of a memory cell by forming a storage electrode by taper etching, and inclining the sidewall of the storage electrode. CONSTITUTION:After formation of a contact hole in the interlayer insulating film 7 in a source region 5, a storage electrode 8 is formed by sticking a polysilicon film all over the surface and patterning it. The polysilicon film in the region to serve as the storage electrode 8 is covered with a photoresist, and using it as an etching-resist mask, the polysilicon film is tapered by etching, and the side face of the storage electrode 8 is inclined. As a result of such taper etching, the sidewall of the storage electrode 8 becomes an incline at 30-45 deg. to the surface of the flat interlayer insulating film 7. Next, a cell plate electrode 10 is formed by sticking a capacitive insulating film 9 and a polysilicon film all over the surface and then, patterning them. Since it becomes easy for oxidation to occur at the corners 8A and 8B of the storage electrode 8, the pinhole of the capacitive insulating film 9 is reinforced by an oxide film, and the withstand voltage of the capacity of a memory cell can be improved.

Title: Power supply circuit
Inventor: OGAWA TATSUO
IPC: G05F1/56
Filed: 1985-02-25
Abstract: PURPOSE:To attain low power consumption by providing a constant voltage element which charges a capacitor with the output voltage and then turns on a switching element and off a switching transistor respectively when the capacitor is charged up to a prescribed level. CONSTITUTION:A commercial power supply AC is connected between terminals T1 and T2 and rectified by a diode D1. This rectified voltage drives switching transistors TRQ1 and Q2, and a capacitor C2 is charged with the outputs of both TRQ1 and Q2. At the same time, the outputs of both transistors are supplied to a constant voltage circuit 1 as the power supply. the constant voltage of the output of the circuit 1 is supplied to a control circuit 2. Here a thyristor SCR is connected to the base of the TRQ1, and the gate of the SCR is connected to a junction between a Zener diode ZD connected to the emitter of the TRQ2 and a capacitor C1. Thus the diode ZD is turned on to charge the capacitor C1 when the capacitor C2 reaches the Zener voltage level. When this charging voltage reaches a prescribed level, the SCR is ignited to turn off the TRQ2. Thus the current is cut to the capacitor C2.

Title: Print correcting system for printer
Inventor: UENO AKIO
IPC: B41J19/18
Filed: 1989-02-17
Abstract: PURPOSE:To correct for respective printing speeds by correcting to print as a pair with respect to individual printing speeds of printing modes. CONSTITUTION:Deviation of digit in positive or negative direction occurs due to a gap epsilon of a toothform by the engagement of a timing belt 2 with a driving timing pulley 3. A printing head is raised from a left end position, starts printing at a position La, prints a distance Li, and stops at the left end to Lb. When this is indicated by the movement of the head apparently in a negative direction, a deviation of a gap epsilon of the belt to the tooth of the pulley occurs, and the deviation of the epsilon occurs in delay as the movement of the head. Dip switches '1', '2', 'n' are provided for designating printing modes to individually correct the deviations of digits in negative direction.

IPC: H04L25/497
Filed: 1993-02-02
Abstract: PURPOSE: To send digital data on a partial response channel by using a pre- encoding technique which can use various transmission constellations (signal point arrangement). CONSTITUTION: A series of signal points are selected from a prescribed fundamental constellation meeting a fixed reference. A signal point is selected from the fundamental constellation as a function of input bits related to the current signal period by a means 9511 in step (a), and this selected signal point is connected to a feedback signal 9513 by a means 9514 in step (b), thereby generating what is called a connection signal point for the current signal period. The feedback signal is a function of the connection signal point expanded for the preceding signal period, and this function is determined by characteristics of a partial response channel. Next, a transmission signal representing the connection signal point is given.  Some of these steps are explicitly performed by using an integrated pre-encoder/constellation mapper 9511, while others are implicitly performed by referring to a table.
