IPC: H02P7/288
Filed: 1979-10-17
Abstract: PURPOSE:To improve responsibility and to reduce higher harmonic ripple by a method wherein when a transistor is turned OFF, first, a fly-wheel current is run, and if a current level does not restore the given value, then, a regeneration current is run to restore the given value. CONSTITUTION:When the set signal is positive, power supply is performed from the DC power source to the motor DM through transistors TR1, TR4 and if a current value reaches the given value, one of transistors TR1 and TR4 is turned OFF and a fly wheel current is run. Next, when the current value does not return to the given level after a certain time has elapsed, then, both transistors TR1 and TR4 are turned OFF and a regeneration current is run to a capacitor CO through diodes D2, D3 to quickly return the load current to the given level. And further, when the set signal is negative, power supply is performed from the DC power source to the motor DM through transistors TR3, TR2, and a fly wheel current is run as when the set signal is positive thus, the load current being returned to the given level.

Abstract: PURPOSE:To measure an accurate intraocular pressure value without deforming the cornea until the surface thereof becomes flat, by measuring intraocular pressure on the basis of the pressure of a fluid when the cornea is deformed to a predetermined degree before reaching an applanation state. CONSTITUTION:An index light source 1 and a projection lens 2 are arranged in the oblique direction of an eye E to be examined, and a light receiving lens 3 and a photodetector 4 are arranged in the oblique direction of said eye on the opposite side. The luminous flux from the index light source 1 is allowed to irradiate the cornea Ec in the direction oblique with respect to the jet direction of the air stream from a nozzle 7. When the cornea Ec receives predetermined deformation by the air stream, the reflected light due to the cornea Ec enters the photodetector 4 arranged so as to become the conjugated relation to the index light source 1 through the lens 3 to detect the deformation of the cornea Ec. The air pressure when the cornea generates predetermined deformation is measured by the pressure sensor 8 in a cylinder 5 to calculate an intraocular pressure value.

When the sunlight entering the photo receiving plate 22 successively scans the photo detectors 230 to 238, the generated current passes through the buffer amplifers 50 to 58, and is fed into the adders 61 to 68. In consequence, the output of the adders 61 to 58 is fed into the comparators 71 to 77. When the output of the adder 68 which picks up the difference between outputs of photo detectors 230 and 238 is above the specified level in the zero detector circuit 78, and a read pulse RP is outputted, the outputs of the comparators 71 to 77, which are angle data, are read. Then, adjusting the photo receiving area of photo detectors 230 to 238 to the measuring angle, and matching the timing of angle reading, the angle is measured without analog error.

Title: Projection-type cathode-ray tube
Inventor: FUJITA JIYUNJI
IPC: H01J29/86
Filed: 1984-06-28
Abstract: PURPOSE:To prevent a gas from being exposed in the effective picture screen when a projection-type cathode-ray tube is slanted by providing a gas reservoir in the position of an uneffective picture screen located above the face of a liquid-tight space and installing rolling members which move along the uneffective picture screen. CONSTITUTION:A gas reservoir 11 is provided in an uneffective picture screen 10a located above a liquid tight space 10. A rolling members 15 are placed in such a manner as to freely rotate along the uneffective picture screen 10a. The rolling members 15 roll on a linear projection 5c located apart from a front plate 7. When the cathode-ray tube is slanted while horizontally maintaining its axis, the rolling members 15 roll along the upper uneffective picture screen 10a into a cooling liquid 9. As the result, the volume of the gas reservoir 11 decreases by the volume of the rolling members 15 and the liquid level of the cooling liquid 9 is elevated. Consequently, the slanting angle can be increased while avoiding entering of the gas reservoir 11 into the effective picture screen and therefore only a small amount of the cooling liquid 9 is necessary.

Abstract: PROBLEM TO BE SOLVED: To decrease material wastes in manufacture and labor in tooling, by deforming an elongate hollow body at each zone. SOLUTION: A contact rail 1 has a hollow tube piece 2 equipped with deformation zones 3, 4, 5. The deformation zone 3 forms an insert tongue piece 6 for connecting a plurality of contact rails with each other.

Title: Cylinder injection type internal combustion engine
Inventor: OGAWA TAKASHI
IPC: F02D45/00
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a large amount of unburned HC by arranging a fuel injection valve in the center of a cylinder head inside wall, arranging an intake valve and an exhaust valve in the periphery of the inside wall face, and injecting fuel from the fuel injection valve toward the opening parts of the intake valve and the exhaust valve at a prescribed time. SOLUTION: An intake valve 7 and an exhaust valve 9 are arranged on the inside wall face of a cylinder head 4, so as to be gradually deflected from the cylinder axial line with increase in height. When the exhaust valve 9 is opened in an intake stroke, air is sucked into a combustion chamber 5 from the intake valve 7, while burnt gas is sucked into the combustion chamber 5 form the exhaust valve 9. Here, fuel is injected towards the opening parts of the intake valve 7 and the exhaust valve 9 from a fuel injection valve 6 arranged in the inside wall central part. Because the injected fuel is pushed back by the air and burnt gas flowing inward, the injected fuel can hardly reach the cylinder bore inside wall face. Consequently, generation of unburned HC is suppressed, and lubrication oil is prevented from being diluted with the injected fuel.
