Patent JP-S62214583-A (JP)
Title: Memory output circuit
Inventor: ISHIO KEISUKE
IPC: G11C11/34
Filed: 1986-03-14
Abstract: PURPOSE:To improve a read speed by providing a precharge circuit bringing an output signal of an output circuit to nearly a threshold voltage when an equalize signal representing address transition is received. CONSTITUTION:When an address input signal is inputted to an address buffer 1, the equalize signal representing the address transition is inputted to an inverter I3. Then an output signal of the inverter I3 goes to L, resulting that MOSFETs Q3, Q4 constituting a precharge circuit 6 are turned on. On the other hand, the MOSFETs Q1, Q2 in the output circuit 5 change their state (one is turned on and the other is turned off) into the state (both are turned off) depending whether the output signal of a sense amplifier 4 is at H or L. Thus, when the equalizing signal rises, the output voltage of the output circuit 5 tends to be a voltage decided by the ratio of the FETs Q3, Q4. Thus, the output voltage of the circuit 5 corresponds to the signal inputted to the circuit just after the signal representing a new storage content is inputted to the circuit 5 to improve the read speed.

Title: Speed switching circuit for single-phase ac motor
Inventor: INOUE YORIAKI
IPC: H02P25/10
Filed: 1980-04-28
Abstract: PURPOSE:To maintain the revolution of a motor irrespective of the variation of its frequency by selectively shortcircuitting a resistor by a frequency change-over switch. CONSTITUTION:In the district where a power source frequency is 50Hz, a frequency change-over switch S5 is switched to ''50'' side. When a combustion switch S4 is shifted to ''HIGH'' side at the time of high combustion, all the resistors R1-R3 are shortcircuitted, a voltage V is applied to a motor M2 as it is, and the motor M2 will rotate at a rated speed. When the switch S4 is shifted to ''LOW'' side, the resistors R1, R2 are connected in series with the motor M2, and the motor M2 is decelerated. In the district where a power source frequency is 60Hz, the switch S5 is shifted to ''60'' side. In this case, the resistor R3 is always connected in series with the motor M2.

Abstract: PURPOSE:To improve the discrimination precision of a device which measures the cracking position of a bed by measuring gamma rays on the ground surface and reduce its size by amplifying the output of a gamma-ray detector so that the spectrum peak of a ray source for calibration is merely constant. CONSTITUTION:The gamma-ray detector 1 detects gamma rays at a ground surface part and its output is passed through an amplifier 2 to discriminate signals in respective energy spectrum regions of potassium-40, thalium-208, and bismuth- 214 by discriminators 3, 4, and 5.

Spectrum signals having lower energy than the three nuclear species are inputted from ray sources for the calibration of cesium-137, etc., to the detector 1 and a peak position adjusting circuit 13 adjusts the amplifier 2 so that a spectrum peak has an invariably constant amplitude. Thus, the small-sized device improves the discrimination precision of the three nuclear species.
