Title: Clamping circuit for work line
Inventor: YAMADA JUNZO
IPC: G11C11/34
Filed: 1985-02-22
Abstract: PURPOSE:To make a connection regardless of the near and far end of a word line and to prevent the word line from floating by resetting a clamping function temporarily at the time of the rising of the word line. CONSTITUTION:A word line clamping circuit 6 is connected to far terminals of word lines 4 and 4' to which a word line clamping circuit 1 is connected. Then MOS transistors (TR) Q8 and Q8' which are turned on and off with a clock phiC for clamping control are added to the word line clamping circuit 6. Namely, the word line clamping circuit 6 is constituted having a precharging circuit consisting of an MOSTR Q7 connected to the 1st power source VCC and the 1st MOSTRs Q8 and Q8', the 2nd MOSTRs Q5 and Q5', and the 3rd MOSTRs Q6 and Q6'. In stand-by mode, nodes N2 and N2' and N4 and N4' are precharged with a clock phiP for precharging. In active mode, on the other hand, the clock phiC for clamping control is varied to a state 'L' before the word lines are driven to reset the clamping function of the far ends of the word lines temporarily.

Title: Inverter circuit
Inventor: AKATSUKA YASUO
IPC: A47J27/00
Filed: 1990-02-14
Abstract: PURPOSE:To prevent the switching speed from being lowered even when the ambient temperature is changed by detecting a temperature change and controlling the circuit so that a drain current is kept constant. CONSTITUTION:A proper gate voltage is applied to depletion type MOS TRs 11, 12 by temperature detection circuits 21, 31 to supply a sufficient drain current to a basic inverter circuit composed of enhancement MOS TRs 12, 13. When temperature rises and a drain current with the MOS TRs 12, 13 is decreased, the temperature detection circuits 21, 31 increase the gate voltage of the MOS TRs 11, 14 to control the circuit so as to recover the drain current. Thus, the switching speed of the inverter circuit is not lowered but the performance at room temperature is maintained.

Title: Method and device for evaluating display image quality characteristic of color cathode ray tube
Inventor: ISHIBASHI NAOMI
IPC: H04N17/04
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To perform quantitative evaluation for a mask howling amount so as to improve designing accuracy and provide highly reliable and high definition display image quality characteristic by cutting off two colors from three light emitting display screen of red, green and blue for providing a single color pattern, forcibly applying external vibration and selectively sensing the emitting light intensity of the phosphor of the display screen by a light receiving sensor. SOLUTION: First, red, green and blue lights are emitted on a display screen, and levels are adjusted such that the outputs of a light receiving sensor 14a provided in an image detection sensor 10 are uniform among the respective colors. Then, a light is emitted by a single color of red on the display screen, and only a red signal is outputted as the output of the light receiving sensor 14a. When external vibration is forcibly added in this state, the output of the light receiving sensor 14a is lowered for its red emitted light intensity following the movement of a shadow mask position, and a green emitted light intensity is increased. Thus, an emitted light intensity is selectively sensed by the light receiving sensor 14a for each emitted light wavelength component of the phosphor of the display screen and thereby mask howling properties are quantitatively evaluated.

Title: Reducing circuit for noise and distortion of fm receiver
Inventor: UKARI TAKENORI
IPC: H04B1/10
Filed: 1981-03-10
Abstract: PURPOSE:To reduce a noise due to multipath distortion and a Reyleigh noise in a weak electric field area at a low cost by receiving the output of an FM demodulating circuit, and using detection output for a noise and a distortion component. CONSTITUTION:An FM radio wave inputted to an antenna 3 is converted into an intermediate frequency signal at a front end 5 and FM demodulation is performed by an IF amplifying and detecting circuit 7, whose output is supplied to a pulsating noise eliminating circuit 9. A noise in the high frequency component of the FM signal is amplified and rectified after passing through the HPF95 of the circuit 9 to appear at a diode D221 as a DC voltage. Since this voltage is in inverse proportion to the antenna input, this voltage is inverted in phase by a tansistor TRQ2 and applied to a TRQ3, which controls the gain of a TRQ1 for IF amplification to perform soft muting. When the antenna input is small, a TRQ4 is turned on by the output of the D221 for the bypassing of a subsignal in a signal inputted to a stereophonic demodulating circuit 11, reducing a stereophonic noise. Then, TRs 229 and 231 are controlled to attenuate a high frequency more and more as the antenna input is less and less, thereby reducing a Reyleigh noise.

Title: Auto reverse type tape deck
Inventor: MIYATANI TAKAO
IPC: G11B15/00
Filed: 1983-03-03
Abstract: PURPOSE:To obtain an auto reverse type tape deck which eliminates a pause of sound artificially by delaying and outputting the last playback signal during reversing operation. CONSTITUTION:A signal VR is normally held at a low level L to turn analog switch 82 is off, and the output of an inverter 83 is at a level H to turn on an analog switch 81. Therefore, a playback signal S which is reproduced from a magnetic tape by a playback head 1, passed through a playback equalizer 2, and amplified by a regenerative amplifier 3 is outputted to a line terminal 5, as it is, through a by-pass circuit 7. On the other hand, the signal RV goes up to H in a specific time Trv after the end of the magnetic tape is detected by a tape end detecting circuit 11, so the analog switch 82 is turned on to hold the output of the inverter 83 at L, so the analog switch 81 is turned off. Therefore, the signal SL generated by delaying the playback signal S right before the inversion of the magnetic tape through a delay circuit 6 is outputted to a line output terminal 5 through the analog switch 82. Consequently, no pause of sound is generated during the reversing operation.
