Title: Removing method and device for scale of hot rolled steel sheet
Inventor: SAKAMOTO KOICHI
IPC: B21B45/08
Filed: 1989-01-09
Abstract: PURPOSE:To omit a pickling process and to remove a scale by removing the scale by the use of a cavitation generated by jetting a high pressure liquid to a hot rolled steel sheet in liquid. CONSTITUTION:When a high pressure water is jetted through a nozzle 1 in water, the lower part of static pressure is generated by the relative velocity between the water and the jetted water and the static pressure in this part is lowered to the saturated steam pressure of water. Local boiling occurs and bubbles 2 are generated in the water by the sudden decrease of the static pressure. When those bubbles are moved to the higher pressure part of scale surface 3, those bubbles are changed and are vanished in a moment by increasing over the saturated steam pressure suddenly. At that time, the water around the bubbles is caused to collide violently and high pressure is generated and the scale on the surface of the steel sheet is peeled by that high pressure; i.e. the removal of scales are performed by the cavitation. Thus it is possible to improve the production efficiency without flowing a base metal as an abrasive material.

Title: Exhaust device for engine
Inventor: YAMAKI YASUTO
IPC: F04F5/16
Filed: 1993-01-11
Abstract: PURPOSE:To improve exhaust gas treatment capacity of an engine for making combustion by mixing fuel with oil. CONSTITUTION:Turning flow is generated in exhaust gas discharged from an exhaust pipe 10, and not yet burnt oil included in exhaust gas is separated. Simultaneously, secondary air is led from a defuser part 8 into muffler main body 1 by ejector effect. Exhaust gas which is not included not-yet burnt oil is led into a reactor 13, and reacted by a catalyst 15 so as to increase its temperature by reaction heat. Exhaust gas in which turning flow is generated is led to the gas discharging port 12a of the reactor 13 along an oil guide part 12 together with not-yet burnt oil, and exhaust gas whose temperature is raised by reaction host is sucked by ejector effect. It is thus possible to purify non- reaction exhaust gas by reactor reaction, and also burn not-yet burnt oil.

Title: Semiconductor optical amplifier element
Inventor: KITAMURA SHOTARO
IPC: H01S5/50
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To reduce the noise light and raise the saturation output by lowering the light reflectivity at the end of an optical signal input element, compared with that at the end of an optical signal output element. SOLUTION: On an InP substrate 11 an active layer 12 is buried with a clad layer 13 to form an optical amplifier element having an optical input and output end faces. The stripe of the active layer 12 is made oblique to the end face 14. The optical input and output ends are tapered as taper structures 16. A window region at the optical input is made longer than the window region 15 at the optical output. For a bevel end face structure, increasing the window region length reduces the reflectivity to result in a low effective optical reflectivity at the optical output end, thus reducing the amplified natural emission and hence the noise light at the optical output to improve the saturation output of the amplified signal light.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of adjusting circuits and reduce cost by constituting so as to satisfy self convergence and a dynamic focus at the same time. SOLUTION: A focusing electrode of a by-potential type electron gun is divided vertically in the beam advancing direction into a G3 electrode 3, a G3' electrode 3', the vicinity of an outside electron beam passing region on facing side of the electrodes 3, 3' is inclined in the opposite direction to the beam advancing direction, and potentials Vf-Vd are applied to the G3 electrode 3, G3' electrode 3'. In this structure, since Vd is specified to Vd>=0, the relation of Vf and Vd always becomes Vf>=Vf-Vd, and the outside electron beam receives focusing force in the direction of the central electron beam. The potential Vd is varied by the deflection scanning of the electron beam with an outer magnetic deflection yoke. Since dynamic focus can be realized with the same circuit, the number of adjusting circuits can be reduced.

Abstract: PROBLEM TO BE SOLVED: To self-diagnose the abnormality of an antenna in a toll collecting/ receiving system independently of communication with an on-vehicle equipment. SOLUTION: A transmission signal 210 from a roadside equipment 100 is converted by a transmission circuit 201 and the converted signal is transmitted from an antenna part 203 as a transmitting radio wave 211. At the time of receiving the radio wave 211, an on-vehicle equipment 400 entering into a communication area puts its own ID on a time slot specified by the transmission signal and returns a receiving radio wave 221. A receiving circuit 202 outputs receiving data 240 extracted from a receiving signal 220 to the roadside equipment 100. A transmission signal specifying the reception of the ID is outputted from the equipment 100 and information necessary for settlement processing is answered from the on-vehicle equipment having the ID.  When the equipment 400 does not exist in the communication area, data 230 extracted from a transmitting time slot of a radio wave 221' directly receiving the radio wave 211 are outputted to a monitoring circuit 204 and collated with the transmission signal 20. At the time of unequal comparison, a signal 250 showing the abnormality of the antenna is outputted to the equipment 100.

Abstract: PROBLEM TO BE SOLVED: To prevent a load by water pressure difference from being applied to an ultrasonic permeation plate to contrive to make the ultrasonic permeation plate thin by installing an indirect tank which can hold liquid for the indirect tank whose level is the same as that of a washing tank and always keeping the level of washing liquid in the washing tank almost the same as the level of the indirect tank liquid in the indirect tank. SOLUTION: When washing a material to be washed 1, first a washing tank 3 is installed in an indirect tank 6 so as not to be contacted with a diaphragm 11. Next, a liquid supply valve 13 is opened to supply liquid 4 for the indirect tank such as pure water to the indirect tank 6, and washing liquid 2 is supplied to the washing tank 3. At this time, the liquid supply is performed while adjusting the liquid quantity of the liquid supply valve 13 so that the level of the indirect tank 6 and that of the washing tank 3 are always the same. When the indirect tank 6 is filled to the maximum capacity, the supply of the liquid 4 for the indirect tank is stopped, and with the liquid 4 for the indirect tank and the washing liquid 2 being at the same level, the washing tank 3 is also filled to a specified level with the washing liquid 2.  In this way, water pressure to the ultrasonic permeation plate 7 is always fixed to prevent a load from being applied to the ultrasonic permeation plate 7, enabling the plate 7 to be made thin.

IPC: F02D41/34
Filed: 1979-01-19
Abstract: PURPOSE:To improve the thermal response and the mechanical strength of a sensor of a hot-wire anemometer for metering an amount of engine intake air by means that the lead wires with each of their end larger in diameter than the lead wire are embedded into a bobbin and one of platinum wires is wound in a reverse direction of the other. CONSTITUTION:Each lead wire has an end larger than the diameter. After the platinum wires are electrically welded to the lead wires, those lead wires are pushed into a glass bobbin 42 softened by heat from both left and right sides. The platinum wires are wound in the relatively reverse direction from the both side of the bobbin 42 to meet at the center where they are welded. The whole body is applied with a coating agent 44. The leat wires 45 won't be removed from the bobbin 42 because each end of the lead wires 45 is thicker than the exit 47 of the bobbin 42. The platinum wires 43, in turn, may reduce in inductance because they are wound in the relatively reverse direction from the both ends of the bobbin 42. Those can improve the mechanical strength and the thermal response.

Abstract: PURPOSE:To obtain a lens which has aberrations improved and has a high NA and to use it as an object lens of a video disc or the like by constituting the lens so that it has a specific refractive index distribution and has one spherical refracting surface at least and satisfies specific conditions. CONSTITUTION:This lens has a refractive index (n) given by an equation n<2>= n<2>0{1-(gr)<2>+h4(gr)<4>+h6 (gr)<6>+h8(gr)<8>+h10(gr)<10>} where n0 is the refractive index of the center and (r) is the distance from the optical axis in the diametric direction and has one spherical refracting surface at least and satisfies conditions of -1.5<(1/h8)<2, -5<h10, etc. In said equation, (g) is a parameter indicating the degree of refractive index gradient, and h4, h6, h8, and h10 are coefficients of terms of high orders of the refractive index distribution. Since terms of high orders of the refractive index distribution are used up to h10 in this manner to compensate the residual spherical aberration, the lens is supe rior in spherical aberration and has the axial capacity. Thus, the distributed index lens is obtained which keeps various aberrations well and has >=0.5 NA and has 0.7 NA which is normally difficult.
