Inventor: KAWAMURA YOSHIHISA
IPC: F02D21/08
Filed: 1982-03-02
Abstract: PURPOSE:To suppress worsening of fuel consumption or the like, by correctively controlling an exhaust gas recirculation (EGR) control valve or the like correspondingly to an ageing change of exhaust pressure due to the blocking or the like in an exhaust fine particle collector provided in the down stream from the branch point of an EGR passage in an exhaust passage. CONSTITUTION:Diaphragm devices 8, 10 respectively driving an exhaust gas recirculation (EGR) control valve 6 and intake throttle valve 7 are operated by negative pressure from a vacuum pump 11 which supplies to generate a vacuum respectively in negative pressure chambers 8a, 10a. In such a device, solenoid control valves 20, 21 are provided respectively in negative pressure passage to each chamber 8a, 10a. While a fixed pressure valve 22 regulating the negative pressure from the pump 11 to almost constant is provided. Each valves 20, 21 is controlled by a control circuit 30 in accordance with an output or the like of a pressure sensor 33 which detects pressure in the upstream from an exhaust fine particle collector 32. When said collector 32 causes blocking to increase exhaust pressure, in accordance with this increase, control is performed such that an opening of the valve 6 is decreased while an opening of the valve 7 is increased.

Title: Evaporative cooling device in engine
Inventor: HAYASHI YOSHIMASA
IPC: F01P3/22
Filed: 1984-02-23
Abstract: PURPOSE:To ensure the fluidity of cooling liquid just after engine starting, in a evaporative cooling device in which the evaporating latent heat of boiled cooling liquid is used for cooling an engine, by arranging a recovery pump, etc. for storing cooling liquid condensed in a condenser, in the vicinity of the engine. CONSTITUTION:A evaporative cooling device cools an engine 1 by absorbing the evaporating latent heat from cooling liquid in a water jacket 2, due to that the cooling liquid in the water jacket 2 absorbs the heat of the engine 1 and therefore boils. The thus generated vapor is led through a vapor passage 6 into a condenser 7 where it is cooled and condensed by an air stream fed from a fan 8, and is returned to the water jacket 2 in the form of cooling liquid under operation of a supply pump 13. In this arrangement, there is provided a recovery tank 30 for storing the cooling liquid condensed in the condenser 7. This recovery tank 30 is arranged as close as possible to the outer wall of the engine 1 so that a heat radiated from the engine 1 readily heats the cooling liquid in the tank 30.

Title: Static image data transmitting method
Inventor: SAEGUSA KAZUNUSHI
IPC: H04N7/14
Filed: 1989-02-13
Abstract: PURPOSE: To exactly transmit picture data necessary for the reproduction of a picture at the time of transmitting the picture data of static pictures divided into plural parts for each block unit by transmitting the picture data to be transmitted at first and at last for each block unit so as to be overlapped plural times. CONSTITUTION: For example, when a difference between the luminance of picture data at the right edge of the first line and the luminance of picture data at the left edge of the second line is large, a first line settling pulse S2 9 and a second line settling pulse S1 8 are mutually affected and those signal waveforms are distorted. However, the luminance difference between the picture data at the end of the first line and the first line settling pulse S2 9 is sufficiently smaller than the luminance difference between the picture data at the head of the first line and the picture data at the head of the second line. Therefore, the picture data at the end of the first line can not be distorted. In the same way, the second line settling pulse S1 is distorted, and the distortion of the picture data at the head of the second line can be prevented.  In the same way, the distortion of the first and last picture data of each line can be prevented.

Abstract: PURPOSE:To obtain a pulsed power laser device with a high pulse peak by a method wherein a superconductive state of a pulse power supplying circuit is self-destructed by a magnetic field induced by the current which flows through the circuit, and the circuit is composed of a superconductor which enables it to function as a switching element. CONSTITUTION:Energy stored at a high voltage capacitor through a DC high voltage power source 1 is supplied to a laser oscillator 12 through a gap switch 3, so that a laser exciting discharge is made to occur in pulse between discharge electrodes 5 through the intermediary of a lead wire 4, and laser exciting rays are resonated with mirrors 7 and 8 to obtain a pulse laser power from a partially transmissive mirror 8. A superconductor 10 is installed very close to a case of a laser 12 and a lead wire lead is short, so that a pulse power supplying circuit 11 is made small in resistance and a large discharge current can be obtained. And, as the superconductivity of the superconductor lead wire 101 is self-destructed by an intense magnetic field induced by the large current so as to turn the lead wire 101 into a normal conductor, the circuit 11 is made to function as a super-high speed switching circuit.

Abstract: PURPOSE:To automatically perform cast binding by providing a concave groove path and a branch path, circulating fused lead, providing a concave hollow at the concave groove path bottom of the downstream of the branch path, moving the upper plate group loading stand horizontally and vertically, and inserting the lug group in the concave hollow. CONSTITUTION:The concave groove path 1 and the branch path 2 are provided at a right angle through the weir plate 4 and fused lead is circulated. The movable plate lug loading stand 8 is provided horizontally and vertically on the upper part of the strap forming concave hollow 5 which is provided at the bottom of the downstream concave groove path of the branch path 2 and the lug group (a) of the plate group A is made to correspond to the concave hollow 5. Then the weir plate 4 moves downward and blacks the branch path 4 to supply the fused lead to the concave groove path 1. Subsequently, the loading stand 8 moves downward and the lug group (a) is inserted into the concave hollow 5. After that, the weir plate 4 moves upward and the fused lead flows into the branch path 4. Since the fused lead is accumulated in the concave hollow 5 in this case, the lead oxide on the surface of the immersion section is removed at the flow of the fused lead. As a result, a solved surface with a new surface is formed and a good strap is formed.

Title: Feeder and recorder equipped with feeder
Inventor: SUZUKI TETSUO
IPC: B41J13/00
Filed: 1990-02-16
Abstract: PURPOSE:To prevent the unnecessary feeding of a recording medium during gear change by having a gear, which transmits the driving force of a driving means to a feeding means, made up with the first gear and the second gear installed on the same shaft as in the first gear so that when the first gear rotates a preset angle or more, rotational movement can be transmitted to the second gear. CONSTITUTION:A gear which transmits the driving force of a driving means to a feeding means is made up with a first gear 9i1 interlocking with a transmitting gear and the second gear 9i2 installed on the same shaft as in the first gear 9i1. Next, since there is necessity for being in phase between the driving gear 9b and a transmitting gear 9h during changing the transmitting gear 9h and for releasing pressure between tooth flanks during interlocking, the driving gear 9b is given a preset amount of positive or negative turn. At this time, although the first gear 9i1 interlocking with the transmitting gear 9h is turned positively and negatively with the driving gear, the rotation of the first gear 9i1 is not transmitted to the second gear 9i2. That means there is no possibility of delivering a recording medium unnecessarily during changing the transmitting gear.
