Title: Operational amplifier
Inventor: OKAMOTO TOSHIYUKI
IPC: H03F3/45
Filed: 1985-09-18
Abstract: PURPOSE:To obtain a high supply voltage variance elimination ratio without changing the other various characteristics by providing a voltage holding means which keeps the output terminal voltage of a differential stage circuit and the power connecting terminal voltage of a driving stage circuit constant independently of the variation of a supply voltage. CONSTITUTION:Loads of input transistors TRs M1 and M2 are TRs M3 and M4. A point X is fixed to a certain voltage by a TR MA1 whose gate is connected to a constant voltage source VB1. A point Y of a driving TR M5 is fixed to a certain voltage by a TR MA2 whose gate is connected to a constant voltage source VB2. When the supply voltage variation elimination ratio to a supply power VDD is taken into consideration, a source point X of the TR MA1 is kept at the certain point approximately even in case of the variance of the power VDD with respect to the differential stage circuit because the current is fixed and the gate of the TR MA1 is connected to a fixed voltage terminal. Consequently, the voltage at an output point A' of the differential stage circuit is approximately constant. With respect to the driving stage circuit, the source point Y of the TR MA2 is approximately constant even in case of the variance of the power VDD because the current is constant and the gate of the TR MA2 is connected to a fixed voltage terminal. Consequently, the output voltage is scarcely affected by the variance of the power VDD.

Title: Semiconductor storage device
Inventor: MURANAKA MASAYA
IPC: H01L21/8242
Filed: 1987-08-24
Abstract: PURPOSE:To improve an access speed and to attain a high density by cutting or connecting, through a high resistance, the middle of the shorter line of a current channel flowing at the time of reading in a memory, which adopts a twisted common drive line sense amplifier. CONSTITUTION:The layout of a sense amplifier SAU in an upper array ARYU and a sense amplifier SAD in a lower array ARYD are mutually constituted in the reverse direction. When the SAUs in the ARYU are all activated, the current flows from a common drive-line CDL 2 through the SAU to a CDL 1. Next, when the SAU is turned off, and the SAD is activated, the current flow from the CDL 1 through the SAD to the CDL 2. Consequently, the channel of the CDL 1 where the current flows is longer, and the current does not flow to the CDL 2 and CDL 2' simultaneously. For this reason, by connecting the CDL 2 with the CDL 2' with the high resistance, a driving time constant can be minimized, and the access speed is improved.

Filed: 1984-10-04
Abstract: PURPOSE:To sufficiently obtain a thrust ratio between hydraulic cylinders regardless of a speed ratio by regulating working fluid pressure supplied to a flow rate control valve according to a change in speed ratio of a belt stepless speed change gear. CONSTITUTION:With tension of a transmission belt 38, oil pressure corresponding to the tension and speed ratio of the transmission belt 38 is produced in the primary side hydraulic cylinder 34.
