Title: Rotor of squirrel-cage type induction motor
Inventor: BABA YOSHINAO
IPC: H02K1/32
Filed: 1983-05-27
Abstract: PURPOSE:To cool efficiently without influencing magnetic characteristics by a method wherein a suitable thrust duct and radial duct are formed in a rotor and a rotor core and end parts of rotor bars of the side of cooling air exhaust are cooled by the cooling air which flows through the radial duct. CONSTITUTION:A thrust duct 12, which extends from an end surface of a rotor core 2 of a cooling air inlet side to the direction of a core shaft but does not reach an end part of the cooling air exhaust side and ends in the core before that, is formed in the rotor core 2. A radial duct 13 is formed from the end of the thrust duct 12 to the outer circumference of the core along the radial direction of the core in the end part of the core 2 of the cooling air exhaust side.

Title: Flow diverter
Inventor: AOYANAGI OSAMU
IPC: F25B41/00
Filed: 1988-04-15
Abstract: PURPOSE:To sufficiently exhibit the ability of a heat exchanger by a method wherein refrigerant flowed into the title device is diverted into more flow passages than the number of downstream side outlet tubes at the intermediate part of the device to be joined together before reaching the outlet port of the flow diversion device, and even if the flow deflection is produced at the intermediate part of the device, the refrigerant is uniformly diverted at the outlet port thereof. CONSTITUTION:Refrigerant flowed into a flow diversion device through an inlet tube 1 thereof is diverted almost uniformly in two flows and flows out of each of outlet tubes 30 and 40 as indicated by the arrow D. Accordingly, the refrigerant flows through independent intermediate-part flow passages 2-5 in the interior ot the main body ot the flow diversion device 7; therefor, even if the refrigerant consists of the two-phase of gas and liquid, no flow deflection is produced. Moreover, the diverted refrigerants are joined respectively at the plural outlet tubes 30 and 40. The intermediate-part flow passages 2-5 are joined together so as to face each other in their positional relations. Accordingly, even if the refrigerant flows in such a manner that a relatively large amount of gas constituent gathers in the vicinity of, for example, the intermediate-part flow passages 2 and 5, the refrigerant with much liquid constituent is diverted on the respective sides of the intermediate-part flow passages 3 and 4 to be mutually mixed with the refrigerant with much gas constituent which flows through the intermediate-part flow passages 2 and 5, whereby the refrigerant without having a big difference in constituent flows out of each of the outlet tubes 30 and 40.

Inventor: YANAGASE KENJIROU
IPC: C02F1/58
Filed: 1983-05-27
Abstract: PURPOSE:To quicken reducing rate of residual chlorine concn. in sea water by admixing a specified amt. of natural sea water to the sea water incorporated with an agent contg. free chlorine at the time when the rate of reduction of the concn. of residual free chlorine becomes slow. CONSTITUTION:Sea water contg. trace amt. of free chlorine is prepd. by adding an agent contg. free chlorine to natural sea water. When a part of the free chlorine in the added agent remains in the sea water a specified time after the addn. of said agent and the rate of reduction of the residual chlorine concn. becomes slow, an amt. of natural sea water corresponding to a portion of a specified amt. of afore-mentioned sea water is admixed to said sea water.

Abstract: PURPOSE: To attenuate the light propagating through clad layer and resin layer to prevent it from superposing on the optical signal transmitted through the core part, by mixing the substance to attenuate the light into the resin layer of an optical fiber for optical transmission consisting of core part, clad layer and resin layer.  
     CONSTITUTION: A clad layer 32 is provided on the outer circumference of a core part 31, and a silicone resin layer 33 is coated on the outer circumference of the former. Supposing the refractive index of core part 31 to be n 1 , the refractive indoex of clad layer 32 to be n 2 , and the refractive index of silicone resin layer 33 to be n 3 , these are in the relation of n 1 >n 2 >n 3 .

Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce rolling by suspendingly holding bracing cables so as to stretch over directly under a traffic part and gradually downward separete from the traffic part from the center part toward both end sides. SOLUTION: Directly under the horizontal girder 6 of a traffic part, at least between the end part of the traffic part and another end part, bracing cables 30 are stretched over. Next the bracing cables 30 are suspendingly held with a plurality of brackets 40 so as to gradually separate downward from the traffic part from the center side of the bracing cables 30 toward both the end sides. In this way, because the horizontal girder 6 of the traffic part is downward pulled with the bracing cables 30 and the girder is upward pulled with a main cable 3, a floor construction and a handrail 10 are not easily moved even if they receive lateral wind load, and hence rolling is remarkably reduced.  Consequently, in this small-scaled suspension bridge 20 of short effective span and for traffic of light weighted object, a walker, a bicycle, a cart, a motorcycle, and the like can be safely passed through.

Title: Zoom lens
Inventor: ADACHI NORIYUKI
IPC: G02B13/18
Filed: 1990-04-12
Abstract: PURPOSE:To decrease aberration variation by moving a 2nd and a 3rd lens element for zooming while varying their mutual interval, and arranging a compensating group in a 5th lens element. CONSTITUTION:The zoom lens consists of a 1st fixed lens element I which has positive refracting power, the 2nd lens element II which has negative refract ing power and moves forth and back for power variation, the 3rd lens element III which has negative refracting power and moves in relation with the 2nd lens element II, a 4th fixed lens element IV which has positive refracting power, and the 5th lens element V which has positive refracting power. For the power variation from the short-focus end to the long-focus end, the 2nd and 3rd lens elements II and III move monotonously from the object side to the image side respectively and part or the whole of the 5th lens element X is moved to correct the movement of the focus position due to the power variation. Further, the relative air interval between the 2nd lens element II and 3rd lens element III varies on the movement path of those lens elements, but a gradual increase from intermediate focal length to the telephoto end is preferable. Consequently, focus position error variation due to the power variation becomes small.
