Title: Subscriber circuit
Inventor: SUDO MINORU
IPC: H04M19/00
Filed: 1989-01-31
Abstract: PURPOSE:To normally execute dial pulse reception by immediately changing a control signal for transition to an off-hook condition and changing the control signal for a fixed time longer than a dial pulse period for the transition to an on-hook condition based on the output of a subscriber line condition decision circuit. CONSTITUTION:A feeding voltage control means 19 is connected to a subscriber line condition deciding means 14 in order to immediately switch an output signal in the case of a change from the on-hook to off-hook and to change the output signal after the lapse of the fixed time in the case of the change from the off-hook to on-hook based on the output of the means 14. The output goes to be the input of a power supply voltage switching signal to a feeding power source 17. Here, by setting the fixed time of a feeding voltage control means 19 longer than the period of the dial pulse, the condition of the high power supply voltage can be continuously maintained while the dial pulse is sent. Thus, when the dial pulse is sent, a loop current much flows and the reception of the dial pulse can be made secure.

Title: Semiconductor integrated circuit
Inventor: SASAKI KATSURO
IPC: H03F3/45
Filed: 1993-02-08
Abstract: PURPOSE:To stabilize an output signal and to make amplification factor high by decreasing or increasing the driving currents of load MOS transistors and a power current responding to the boosting and dropping of an output potential. CONSTITUTION:A signal amplifier circuit is provided with a control circuit A and imparted with a characteristic by which an output voltage is increased or decreased in proportion to the electrical potential levels of signals S1, S2. Further, the current of a current source B is controlled by signals S1, S2. When currents of differential N-Nchannel MOS transistors Q3, Q4 are increased by the process fluctuation at the time of a manufacturing, etc., and electrical potentials of output signal S1, S2 are dropped the control circuit A increases currents of P-channel MOSs Q1, Q2 and also decreases the current o the current source B. Furthermore, when electrical potentials of the Q1, Q2 are boosted and electrical potentials of signals S1, S2 is boosted the control circuit decreases the currents of the Q1, Q2 and at the same time increases the current of the current source B. Thus, a stable output of the driving current for MOS transistors is obtained without decreasing an amplification factor.

Title: Memory device
Inventor: YAMAMOTO SHOHEI
IPC: G11C16/06
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent data stored in a memory cell from being mistakenly overwritten. SOLUTION: Inverters 30, 31 are respectively connected to ends of a bit line pair B, B/. A threshold value of each of the inverters 30, 31 is set to be at the same level as that of an inverter which constitutes a storing section in a memory cell 10. When data is read out from a selected memory cell 10, an electrical potential of the bit line B or B/ is decreased depending on the data. When the electrical potential reaches this threshold value, outputs of the inverters 30, 31 change. An output signal of a NOR gate 32 changes based on the change in the output of the inverter 30 or 31 to compulsorily deactivate selection signals A1 -An which are supplied to word lines W1 -Wn by AND gates 331 -33n . Thus, the memory cell 10 is disconnected from the bit line pair B, B/, thereby preventing a further decrease in the electrical potentials of the bit line pair B, B/.

Abstract: PURPOSE: To provide a method of manufacturing a double-polished wafer polished to high smoothness on both sides, whose front and rear are easily discriminated from each other. CONSTITUTION: The mirror-polished front side and rear side of a silicon wafer are capable of being discriminated from each other. For instance, the silicon wafer is etched with mixed acid which contains 1% KOH or sulfuric acid to make one of its sides clouded. Or, an oxide film or a polysilicon film is deposited on the one side of the wafer. An identification means is printed on the one side by a laser. Furthermore, the front side and rear side of the wafer are discriminated from each other by the angle of beveling. Or, the beveled edge of the one side is polished. By processing done to a wafer as above, the mirror-polished front side and rear side of the wafer are capable of being discriminated from each other, so that the front side is prevented from being mistaken for the rear side in a device process.  Moreover, in this case, the roughness height (Peak-Valley) of the rear side is set below 0.5μm.
