Patent JP-S58123225-A (JP)
Title: Transistor circuit
Inventor: TOKUSHIGE KAZUO
IPC: H03K19/017
Filed: 1982-01-19
Abstract: PURPOSE:To obtain a transistor circuit which operates stably, specially an MOSFET inverter circuit which uses no capacitive feedback without any influence of noises. CONSTITUTION:When a fine noise is inputted to an input terminal IN2, a pulse corresponding to the input noise appears at a node N23 and the potential at a nose N27 drops. A node N22, however has the level suppressed by a transistor (TR) Q25 connected at its gate terminal to the node N27 and the potential at the node N22 never rises unless the potential at the node N27 drops sufficiently. Therefore, none of potentials at nodes N24 and N25 and of an output OUT2 drops and any influence of the input fine noise is exerted on the output. If such a noise that the potential at the node N27 is lowered approximately to the earth potential is inputted, the potential of the output OUT2 drops slightly, but recovers immediately up to a power voltage.

Title: Integration circuit
Inventor: YAMAMOTO TADATAKA
IPC: G06G7/186
Filed: 1986-01-17
Abstract: PURPOSE:To improve accuracy in a circuit by performing an integral control action supplying a D/A conversion output between a digital signal held at a counter circuit and the digital signal subtracted with a cyclical subtraction operation to the non-inversion input terminal of an operational amplifier circuit. CONSTITUTION:By integrating a pulse signal impressed at an input terminal, an electric power value is found. The integral control action is continued until an integral output voltage Vo arrives at a reference voltage +Vref, and when the integral output voltage Vo arrives at the reference voltage +Vref, a voltage comparison circuit VC detects it, and resets a capacitor C. Afterwards, a subtrac tion circuit HS is operated with a timing signal (phi) cyclically, and a subtraction for the lowest-order bit of the digital signal formed with a counter circuit CNT is performed. Therefore, when a subtraction operation for the digital signal formed with the counter circuit CNT at the subtraction circuit HS is performed, the output voltage Vos of a D/A conversion circuit DAC is lowered from a step voltage Vn to Vn-1. In this way, an error share is reduced to almost half of one step voltage DELTAV, thereby improvement integral accuracy can be contrived.

Title: Optical fiber type polarized light beam splitter
Inventor: TAKUMA TAKEYOSHI
IPC: G02B27/28
Filed: 1988-01-18
Abstract: PURPOSE:To attenuate an unnecessary polarized wave and to obtain a splitter of a high quenching ratio by constituting the splitter so that in two emitting ports of a coupler, as for one of them, a slow axis is allowed to coincide with a transmission axis of an optical fiber type polarizer, and the other is allowed to be orthogonal to the transmission axis. CONSTITUTION:When a light beam which is polarized in the long axis direction of an elliptical jacket 12 is made incident on an incident port 4 of a direction coupler 1, since the polarized wave of an output port 6 of transmission side coincides with a transmission axis of a polarizer 2, it passes it through at a low loss, and emitted from an emitting port end 8. On the other hand, a polarized wave of an emitting port 7 of a coupling side coincides with a jacket short axis and goes to orthogonal to the transmission axis, therefore, attenuated and not emitted from an emitting end 9. In the same way, when a light beam which is polarized in the short axis direction of the jacket 12 is made incident on the port 4, it is not emitted from the output end 8 but emitted from the output end 9 without being attenuated. In such a way, an unnecessary polarized wave from the emitting port is attenuated and a polarization beam splitter of a high quenching ratio is obtained.

Title: Picture-signal correction system
Inventor: HANAOKA HIDEYUKI
IPC: H04N1/401
Filed: 1981-01-19
Abstract: PURPOSE:To use a low-speed A/D converter by reading a reference surface several times by an image sensor, by finding corrected values of some bits by performing A/D conversion every time the reference surface is read, and by finding corrected values of all bits finally. CONSTITUTION:Before picture information is read, a white reference surface is read by an image sensor and a digital signal (e) obtained by processing the obtained analog signal by A/D conversion 8 through a sample holding circuit 7 is used to address an ROM9, thereby writing a corrected value from the ROM9 in an RAM10. When the quantity of light from a light source becomes constant during the repetition of said operation, the level of the signal (e) becomes constant and once a light-quantity detecting circuit 12 detects that, an N-time read control circuit 15 supplies a frequency-division clock P to each circuit. The output of the circuit 7 is processed by A/D conversion 8 at a low frequency 1/N to store corrected values of respective bits in the RAM10, so that corrected values of all bits are stored finally. Then when an actual original is read, a subtracter 11 subtracts the corrected value of a corresponding bit from the RAM10 from the output of the circuit 7, thus correcting variance in ref- erence level.

Title: Power train supporting structure
Inventor: NAKADA MORITSUNE
IPC: B60K5/02
Filed: 1991-01-25
Abstract: PURPOSE:To suppress the early fatigue of a torque tube connecting part by forming vehicle power train supporting structure in such a way as to avoid the concentration of stress onto the torque tube connecting part at the sudden stop time of a vehicle. CONSTITUTION:A power unit (an engine 1 and a transmission 2) is supported to a vehicle body at a supporting point RM positioned lower than the center-of- gravity point G of the power unit and also at a supporting point LE positioned higher than the center-of-gravity point G by a stopper member. When external force acts upon the center-of-gravity point G at the sudden stop time of a vehicle, reaction acts upon the supporting point RM and also upon the supporting point LE. This avoids the generation of moment around the supporting point RM and also avoids the concentration of stress onto a torque tube connecting part 9.
