Title: Dc power source
Inventor: OOMORI KENZOU
IPC: H02P9/14
Filed: 1982-05-18
Abstract: PURPOSE:To prevent the damage of a load and a power source by controlling a voltage on the basis of the outputs of a current range switching circuit which converts the load current to the value within the prescribed range and a voltage drop compensating circuit which obtains the voltage drop compensating value of an electric circuit. CONSTITUTION:AC power which is outputted from AC generator to AC power source lines 1a-1c is supplied through AC/DC converter 43 to a load 15. A current range converter 26 converts the current signal from a current transformer 21 in response to the selected current range, and applies it through a diode bridge 27 and a diode 31 to a control circuit 43. A voltage drop compensating circuit 19 applies the voltage drop compensation signal of the line to a control circuit 38 in response to the current signal from a current transformer 18. The circuit 38 controls the field current of an AC generator in response to the output voltage detection signal of the AC generator and the compensation signals.

Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of exhaust emission due to a response delay, by quickening response of air/fuel ratio control when an opening of an EGR (exhaust gas recirculation) valve or an intake throttle valve is large. SOLUTION: In an air/fuel ratio control method for a diesel engine having an EGR valve 42 provided in an EGR passage 41 recirculating part of exhaust gas to the diesel engine 11 by connecting its intake/exhaust passages 16, 24 and an intake throttle valve 25 provided in the intake passage 16 to control air/fuel ratio in the target air/fuel ratio in accordance with an operating condition of the engine, a deviation amount of air/fuel ratio relating to the target air/fuel ratio is corrected by variably changing an opening of the EGR valve 42 when the EGR valve opening is decided less than a prescribed opening, by deciding whether the opening of the EGR valve 42 exceeds the prescribed opening or not.  When the EGR valve opening is decided to exceed the prescribed opening, a deviation amount of air/fuel ratio relating to the target air/fuel ratio is corrected by variably changing an opening of the intake throttle valve 25.

Title: Output control device for engine
Inventor: NAGAOKA MITSURU
IPC: F02D41/14
Filed: 1988-04-06
Abstract: PURPOSE:To improve acceleration property by determining an output increasing correction by means of the first and second coefficients, when engine output is controlled in response to an acceleration pedal stepping amount and enlarging especially an increasing correction amount when the acceleration pedal stepping amount is in an intermediate position. CONSTITUTION:In an output control means B, output of an engine E is controlled by an output adjusting means A, according to the stepping amount of an acceleration pedal C detected by a detecting means D. At this time, the basic characteristics of the acceleration pedal stepping amount and the engine output are set comparatively small so as to retain a speed holding characteristic. When an acceleration demand is proposed otherwise, a correction amount set means G determines an output increasing correction, in response to the demand, by the first coefficient which makes increasing correction the largest characteristic in the intermediate position of the acceleration stepping amount, and the second coefficient based on the running condition for responding to the degree of acceleration demand, so that the output increasing correction is carried out through a correction means F. Thus, it is possible to aim at the compatibility of a speed control property to an acceleration control property.

Abstract: PURPOSE:To prevent the generation of an excessive damping force and control a discomfort vibration which takes place in a high-speed running vehicle by providing a check valve for streaming oil from a rod inner chamber and a cylinder inner chamber to a chamber other than those, when the pressure within the two chambers is increased to more than a fixed value. CONSTITUTION:In a device where a rod inner chamber 4 and a cylinder inner chamber 5 are interconnected by means of a check valve 10 which permits the flow from a fixed throttle 11, through the rod inner chamber 4, into the cylinder inner chamber 5, when the pressure either in the rod inner chamber 4 or in the cylinder inner chamber 5 is raised to more than a fixed value, a check valve 8 for contracting or a check valve 9 for expanding is operated to stream oil into the cylinder inner chamber 5 or the rod inner chamber 4 respectively. When the velocity of expansion and contraction of a rod 3 is low, the damping force is decreased either by a fixed throttle 11 or by the fixed throttle and the check valve 10, and then, the velocity of expansion and contraction thereof becomes high, the oil in the two chambers flows either through the check valve 8 for contracting or through the check valve 9 for expanding, and accordingly, the damping force is prevented from increasing to more than a fixed value, and a discomfort vibration can be controlled.

IPC: G11B20/10
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To easily interleave digital data at a truly equal interval at high speed display reproduction at a multiple of N of the speed by reading L sets of digital data from a data recording means in a way that the number of times of reading is equal at each reading at a multiple of N reproduction speed or is equal to the number of times of reading at reproduction at a usual speed and rearranging the read data in the order of digital data. SOLUTION: In the case of reproduction at a speed of multiple of 4, a read frame group designation section designates frames 1, 14, 9, 21, 5, 18 as first read frame groups. In the case of designating the frame groups, read processing is not concentrated on a specific hard disk unit. A read section reads the designated frames 1, 14, 9, 21, 5, 18 from 1st-6th hard disk units 11-16 respectively. A frame rearrangement section rearranges the frames 1, 14, 9, 21, 5, 18 in the order of frame numbers and provides outputs of the frames 1, 5, 9, 14, 18, 21 in this order to output channels and then reads succeeding frames similarly.

Abstract: PURPOSE:To prevent cracking of ceramics and improve their matching characteristics by providing a waveguide section at the upper and lower parts of a terminal attenuator, respectively, and soldering loss and backup loss ceramics, bordering on a short-circuiting plate which shorts the inter-waveguide section. CONSTITUTION:Waveguide sections 8 and 8' are provided at the upper and lower parts of a terminal attenuator 6 in a waveguide 4 and the inter-waveguide section is electrically shorted by short-circuiting plates 10 and 10' on each end. Then, loss ceramics 11 and 11' for progressive and regressive waves and backup loss ceramics 12 and 12' are soldered bordering on the short-circuiting plate 10 and 10', respectively. In this case, the soldering area to both the short-circuiting plates 10 and 10' are made equal and their thickness is made thin. This prevents cracking of the loss ceramics 11 and 11' and backup loss ceramics 12 and 12' due to difference in heat expansion coefficient of each material and besides permits the backup loss ceramics 12 and 12' to apply distribution loss in a cavity 5. As a result, their matching failure can be prevented and their matching characteristics are improved.
