Title: Solid-state image pickup device
Inventor: TANIGAWA HIROSHI
IPC: H04N5/341
Filed: 1991-03-07
Abstract: PURPOSE:To improve the dynamic range and reduce the influence of a noise component by increasing the amount of transferrable electric charges in such a way that the width of transfer gate electrodes for generating transfer gate voltages is widened and that of another transfer gate electrodes for generating potential barriers is reduced. CONSTITUTION:The ratio of the width W1 of even-numbered transfer gate electrodes G for generating transfer elements positioned adjacent to each photodiode P on both sides of a transfer gate Tg in the electric charge transferring direction to the width W2 of odd-numbered transfer gate electrodes G respectively provided between the even-number electrodes G in the electric charge transferring direction is increased as much as possible. In addition, the width W2 is made larger than the double of the buried channel junction depth XJBC of an n-type impurity layer buried in a well layer for forming a vertical electric charge transferring path Li. As a result, more distinct pictures can be reproduced, because the dynamic range can be improved and the influence of smears can be reduced.

Title: Crawler running device for agricultural machine
Inventor: CHIBA MASAAKI
IPC: B62D55/088
Filed: 1987-03-18
Abstract: PURPOSE:To positively remove mud adhered to the inner periphery of a crawler belt, by a method wherein a disc-shaped scraper is mounted for rotational drive in a state that the outer periphery of the scraper approaches or makes contact with the under surface of the inner peripheral part of the crawler belt in a position in the vicinity of the rear end of the crawler belt. CONSTITUTION:An arm 8 is mounted to the rear end of a truck frame 5, and a scraper 7, formed in a discshape and having resilient material 9 engaged externally at the outer peripheral part, is pivotally supported to the tip of the arm with its back toward the arm. The scraper is rotationally driven by means of a friction force in linkage with rotation of a crawler belt 3. During turn of a machine body, the scraper enters the inner peripheral surface of the crawler belt 3, and mud fed in a state to be adhered to the outer parts of core protrusion 10 is orderly extruded on the under surface of the peripheral part of the belt by means of the scraper 7. In this case, since the resilient material 9 of the scraper 7 is forced into contact with the under surface of the inner peripheral part of the crawler belt 3, even a small amount of mud can be removed, and on amount of mud adhered to the scraper 7 is decreased. This constitution enables elimination of adverse influence exercised on work by a lump of earth.

Title: Automatic feeding roller machanism
Inventor: MATSUSHIMA TAKEO
IPC: B30B15/30
Filed: 1978-06-02
Abstract: PURPOSE: To automatically supply and position sheet metal for press operation in conjunction with upper die movement, by installing one-way clutches which drive feeding rollers when the upper die moves upward.  
     CONSTITUTION: A material 27 to be pressed is prepared at the feeding side of a lower die 1 in a press mechanism. A sleeve casing 14, together with an upper die 2, moves upward, and when the upper die 2 reaches to a certain height, a stopper 15 comes into contact with the bottom of the casing 14. The stopper pulls up a chain 21 which is engaged with two splockets 10 to drive one-way clutches 9. With this rotational force, two rollers 4 transfer the material 27 to the lower die while the material pushes away the pressed sheet. When the upper die 2 moves downward, the rollers 4 do not rotate because of one-way clutches even though the chain goes down due to the weight of a ram 26.

Abstract: PURPOSE:To aim at rationalizing the air-fuel ratio of an engine during starting and warm-up operation thereof, by providing a pressure balance type fuel system in which is fuel pressure regulator for controlling the fuel pressure downstream of a main fuel jet or a low speed fuel jet is disposed. CONSTITUTION:During cranking, the intake vacuum downstream of a throttle valve 102 is weak, a starting fuel shut-off valve 129 is opened so that starting fuel is fed into a bypass air passage 112 from a main fuel jet 109 and a bypass fuel passage 131. At this time, when fuel flows through a starting fuel passage 127, pressure regulators 112 shut off main and low speed fuel passages 108, 110 to maintain the ratio of mixture at a suitable value. Further, when the engine is started, the starting fuel passage 127 is shut off to shift the engine operation into warm-up operation. Further, when the rotational speed of the engine is increased, negative pressure is effected in outer and variable venturies 105, 104, and the fuel pressure regulators 122 control the flow rates of fuel in the main and low speed fuel passages 108, 110 in accordance with the flow rate of bypass air through the passage 122. Thus, it is possible to maintain the air-fuel ratio of the engine at a constant value.

IPC: G11B7/135
Filed: 1980-05-19
Abstract: PURPOSE:To reduce the self-connection effect, by using a concave cylindrical lens and a convex cylindrical lens which have the curved surfaces in the direction parallel to the junction surface of a semiconductor laser and then distributing the curved surfaces of lenses toward the parallel optical section. CONSTITUTION:The curved surface alpha of a cylindrical lens 14 is provided at the side of a semiconductor laser 11. As a result, the reflected beams on the surface alpha do not become parallel to reduce extremely the feedback light volume without forming an image of reflected light on the junction surface of the laser 11 owing to the reflection on the surface alpha and the function of a condenser lens 13. The plane epsilon of a cylindrical lens 16 is disposed at the side of the laser 11. As a result, the reflected light on the plane epsilon is sent back toward the laser 11 by being further increased and dispersed, and thus the volume of the reflected light to be fed back to the laser 11 is extremely reduced.

Abstract: PURPOSE:To increase the amount of impregnated active material by reducing salt content in the first impregnation, the gradually increasing immersing time in salt solution from the second impregnation. CONSTITUTION:For example, a porous nickel sinter is immersed in nickel nitrate solution having a specific gravity of 1.40 at 25 deg.C for 2 minutes, taken out from the solution and allowed to stand at 50 deg.C for 10min to remove excess nickel nitrate on its surface. The porous sinter is immersed in 20% NaOH solution at 50 deg.C to convert nickel nitrate into active material, then washed. From the second impregnation, the concentration of nickel nitrate solution is increased to sp.gr. 1.60 and impregnation time is also increased to 10, 20, 30, 60, and 90min in order to impregnate active material. Thereby, tendency to saturate the amount of active material caused by repeated impregnation is suppressed and the amount of impregnated active material is increased.

Title: Voltage comparator
Inventor: YONEYAMA JIYUICHI
IPC: G01R19/165
Filed: 1981-04-30
Abstract: PURPOSE:To erase offset voltage, by detecting the difference between a reference voltage and an unknown input voltage by an inverter and supplying the difference of potential between the input and output terminals of the inverter to the load element of an F/F. CONSTITUTION:When switches S1, S3 and S4 are closed with switches S2 and S5 opened, respectively, a capacitor C is charged by a reference voltage VR and via the switch S1. Then the switch S2 is closed, and an unknown input voltage VX is applied. Thus the voltage of an input terminal P<1> varies from VR to VX, and the voltage equivalent to the degree of change is sent to an inverter I to be amplified. The voltage of the input/output terminals of the inverter I is applied to the gates of MOSFETs Q1 and Q2 which function as the active load elements of a flip-flop F/F. When the switch S5 is closed with the switch S4 opened, the MOSFETs Q3 and Q4 are made active and broken, respectively in the case of VX>VR. Then the FETQ4 becomes active in the case of VX<VR. Thus no offset voltage is caused since a short circuit is previously given between the input and output terminals of the inverter I.
