IPC: H03G3/20
Filed: 1982-06-10
Abstract: PURPOSE:To make a speedy return to a normal output even if a large-level noise pulse is mixed, by controlling the discharge current of a discharging circuit connected to the time constant circuit of a peak value detecting circuit on the basis of the output of a level detecting circuit. CONSTITUTION:An adding circuit 5 adds the delay pulses of a horizontal synchronizing signal from a delay pulse generating circuit 7 to blanking parts of a video signal and the resulting sum signal is supplied to the peak value detecting circuit 8 and a the level detecting circuit 9. The circuit 9 supplies the sum signal to the discharging circuit 10 only while the level of the sum signal is between a clamp potential and a reference potential. The circuit 10 discharges a current corresponding to the difference between the sum signal and reference potential only when the level of the sum signal is lower than the reference potential. The output of the circuit 8 is supplied to a gain control circuit 2 as a control signal. Therefore, even when a composite video signal at an output terminal 4 drops in level, i.e. when a noise pulse with a relatively large level is mixed with the composite signal, the output of the circuit 8 returns to a normal level speedily, so the output of the output terminal also returns to the normal level speedily.

Title: Measurement of atmospheric pressure of internal combustion engine
Inventor: HIBINO YOSHITAKA
IPC: F02D45/00
Filed: 1987-04-24
Abstract: PURPOSE:To measure the atmospheric pressure by the simple constitution of measuring the atmospheric pressure on the basis of the intake pressure in the highly loaded state of an engine and renewing the measured atmospheric pressure according to the lapse of the operation time in which the operation parameter varies over a prescribed value in the deceleration of the vehicle. CONSTITUTION:During the operation of a vehicle, it is judged that a differential pressure switch 50 is turned ON, namely if a throttle valve 30 is in perfect opened state or not. If the judgement is 'YES', it is judged if the detection value of an intake pressure sensor 40 is less than a prescribed value or not, and when the value becomes equal to the detection value in the case when the throttle valve 30 is in perfectly opened state, the max. atmospheric pressure is set to a prescribed value (lower limit value of the atmospheric pressure as measurement object). Then, the correction value of the intake pressure is searched according to the engine revolution speed, and the atmospheric pressure value is estimated by adding the correction value with the detected intake pressure value. When the deceleration state of the vehicle is detected, the operation time in which the detection value of the engine operation parameter exceeds a prescribed value is measured, and the atmospheric pressure at this time is renewed according to the operation time.

Title: Optical recording medium
Inventor: FUJITA MINORU
IPC: G11B7/24035
Filed: 1987-04-24
Abstract: PURPOSE:To attain excellent light resistance and oxidation resistance by forming a sensitivity enhanced layer and a thin metallic film layer on a substrate in this order, and forming the former layer with a material that deforms with heat energy of a write beam. CONSTITUTION:On the substrate 2, the sensitivity enhanced layer 3 is formed with gelatine, caseine, etc., on the top of which the thin metallic film layer 4 of Cr, Ni, etc., is formed. That is, by combining the layer 4 which is of low writability and the layer 3 which easily deforms with heat, the function is separately imposed so that the absorption of light is achieved by the thin metallic film layer 4 while the thermal-deforming is achieved by the sensitivity enhanced layer 3. When a write beam 6 is radiated on this recording medium 1, the sensitivity enhanced layer 3 deforms due to heat and a part surrounding a spot elevates, and thus information pit is generated. Hence, the metal layer does not need to deform with the heat, hence it does not need to be Te or else that is of low resistance to oxidation. Therefore, the oxidation resistance can be improved. Also, since the sensitivity enhanced layer 3 is convered by the metal layer 4, light resistance is improved.
