Title: Lubricating oil returning device in internal-combustion engine
Inventor: SUGANAMI TOMOJI
IPC: F01M1/06
Filed: 1985-01-29
Abstract: PURPOSE:To reduce the holdup amount of oil on a buffle plate provided below a crank shaft to partition between a crank chamber and an oil sump in an oil pan, by forming oil return holes in the vicinity of and direct below an oil return passage. CONSTITUTION:An oil return passage 23 is formed in one side corner section of a cylinder block 1 and a cylinder head 2, being extended therebetween and having a block side passage 23b opened at its lower end to a crank chamber 24. A valve plate 26 made of a metal plate is secured by bolts 27 to the lower surface of a bridge member 12 which is fixed to a plurality of journal walls 10 of a crank casing section 12 by means of bolts together with a bearing cap 11. Oil return holes 29, 30 are formed in the buffle plate 26 at the lowermost bottom 261 and at a position direct below and in the vicinity of the oil return passage 23. Further, oil which has flown down through the oil return passage 23 flows down into an oil sump 28 through the oil return hole 30 without oil stagnating on the buffle plate 26.

Title: Method and apparatus for penetration of structure into bottom ground under water
Inventor: KIDA HIROSHI
IPC: E02D23/08
Filed: 1985-01-29
Abstract: PURPOSE:To easily penetrate a structure into the bottom ground under water by a method in which air is jetted downwards from the lower end of a structure to form a cavity in the ground by forcibly flowing out the soil particles of the ground, and the structure is penetrated into the cavity. CONSTITUTION:A structure 2 is landed on the seabed ground 1, and a compressor 6 is actuated to jet air from the tip of a compressed air pipe 5. Whereupon, the compressed air goes up in the form of bubbles 10 in the slit 9 surrounded by an outer wall plate 3 and a rectifying plate 4. A flow 11 is produced in the neighborhood of the lower ends of the outer wall plate 3 and the rectifying plate 4, and the soil particles 12 of the ground 1 are moved upwards with the flow of the bubbles in the slit 9. The ground near the lower ends of the plates 3 and 4 is locally degraded and cavity 13 is formed. The structure 2 settles by its own weight with the plate 4 into the cavity 13 and then penetrates into the ground 1.

Filed: 1986-01-27
Abstract: PURPOSE:To obtain a rotation preventing mechanism having low sliding resis tance while being easy to machine by forming plural column-shaped projections on the bottom face of a revolving scroll and providing a circular groove which houses each of said projections which is always brought into contact with is inner peripheral surface when said revolving scroll is revolving, on a block. CONSTITUTION:A rotation preventing mechanism is formed in such a way that, plural column-shaped projecting parts 7 are formed on the bottom face of a revolving scroll 2, circular grooves 8 for housing the projecting parts 7 respectively are formed on the top face of a block 3, and the projecting part 7 is always brought into contact with the inner peripheral surface of the circular groove 8 when the revolving scroll 2 is revolving. Since a lubricating passage 9 is connected into the circular groove 8, oil is always fed into the circular groove 8, remarkably reducing sliding resistance on that part. Also, a simple structure makes machining very easy.

Abstract: PURPOSE:To get rid of a malfunction of the logical equipment, which is apt to occur by the inductive voltage, by transmitting a light from the fixed polarizing plate to the photodetection part through the polarizing plate which is interlocked with operation of the mechanical moving member. CONSTITUTION:In case of the OR logical equipment, the polarizing plates 18 incorporated in the operation mechanism 17 of the gas breaker CB of 3 phase are arranged at 45 deg. polarized angle to the polarizing plate 20 contained in the light emission 15.

Title: Seat belt retractor
Inventor: KAMIJIYOU TAKESHI
IPC: B60R22/44
Filed: 1982-02-03
Abstract: PURPOSE:To obtain a captioned retractor with a function of tension lock prevented from loosening by constructing to take out the winding and the rewinding of a belt-winding shaft as pulse signals for hooking a stopper to ratchets when the difference between both signal counts is equivalent to a fixed amount of loosening. CONSTITUTION:When a belt 3 is drawn out, a pulse signal is outputted from a UP pulse generator by a tumbler switch 12. Then, when a buckle is set for winding up to tighten a body by a winding spring 4, a DOWN pulse signal is outputted. When a belt 3 is drawn out by a few centimeter and operated to be wound up, an unillustrated counter starts counting. When the count comes to a fixed value, for example, 3, a solenoid is excited, and a stopper 8 is hooked by ratchets 5 and 6 to check the rotation for winding. This construction permits to obtain a seat belt retractor with a function of tension lock with a preventive mechanism from loosening.

Abstract: PURPOSE: To eliminate an accumulator and to prevent the oil pressure change at the time of igniting burners by the operation of a valve by providing a first valve of an instantaneously switching valve type and a second valve of a gradually opening and instantaneously closing type having an oil damping unit at supply passages to the burners. CONSTITUTION: When igniting during stopping of other burner, a fuel oil supply control valve 2 and a fuel oil circulating valve 3 are opened before the ignition, and the oil is circulating in a fuel oil supply header tube 1. First, the valve 3 is closed, the oil pressure of the tube 1 is stored, then a first valve 5 is opened after the time limit when a second valve 6 is fully opened by previously opening the valve 6, the pressure is stabilized in a short time by the pressure storage effect, and ignited. In the case of burning of the other burner, the first and second valves 5, 6 are simultaneously opened, and the oil is gradually supplied to the burner by the effect of gradually opening the valve 6. As a result, the stable ignition is conducted without abruptly dropping the pressure of the tube 1.  The gradually opening effect of the valve 6 is conducted by regulating the throttle amount of the speed control valve 9 of an oil damping unit 8.

Title: Optical waveguide
Inventor: FUJIMA HARUMI
IPC: G02B6/12
Filed: 1983-02-04
Abstract: PURPOSE:To make an increase in loss neglible as compared to the case of using an ordinary glass base plate up to the temp. at which the high polymer compd. of the base plate or optical waveguide layer is deteriorated by heat by constituting the optical waveguide layer of an org. compd. or high polymer compd. CONSTITUTION:A polymethyl methacrylate which has 1.49 refractive index and is known as a plastic lens material is used as a base plate 21 and an epoxy resin having 1.50 refractive index is used as an optical waveguide layer 22. Since the difference in the refractive index is 0.01, about 2mum film thickness is satisfactory with the optical waveguide of a single mode and the loss of light is extremely low. The coefft. of expansion is 6X10<-5>/ deg.C with the plate 21 consisting of the polymethyl methacrylate and 3X10<-5>/ deg.C with the layer 22 consisting of the epoxy resin, which values are proximate and since the change in refractive index is -1X10<-4>/ deg.C with both, the characteristic is stable up to around 10 deg.C. As a result, the optical waveguide which decreases the change in the propagation constant and light loss is realized.
