Abstract: PURPOSE:To efficiently supply the mixed gas into a combustion chamber according to the operation state by constituting a suction pump which sends under pressure the mixed gas into the combustion chamber through a scavenge port, from a plurality of blades installed on the outer peripheral part of a crank web and the inner wall of a crank chamber set close to the blade. CONSTITUTION:On the outer periphery of a pair of crank webs 16 which are oppositely installed on the both sides of the crank pin 7 of a crankshaft 6, a plurality of blades 17 are installed in radial form at equal intervals over the whole periphery. A pair of arcuate-shaped mixed gas passages 19 are formed on the inner wall of a crank chamber 11 so as to be set close to each blade 17, and the inlet (a) of each passage 19 communicates to a suction port 13, and an outlet (b) communicates to an exhaust port 14. A suction pump P is constituted of the blade 17 and the mixed gas passage 19. When the engine E is in operation, the mixed gas sucked from the suction port 13 is formed into an eddy current in the mixed gas passage 19 and sent under pressure into a combustion chamber 10 through a scavenge port 14, and ignited and combusted.

Title: Magnetic head and magnetic recording and reproducing device
Inventor: IHARA KEITA
IPC: G11B5/127
Filed: 1986-10-31
Abstract: PURPOSE:To improve the envelope of an output of a head reproduction by using nonmagnetic bases having different hardness so as to clip a magnetic substance forming a magnetic path and contacting the base having a smaller hardness with a magnetic tape earlier. CONSTITUTION:The magnetic substance 1 of a helical scanning rotary head is clipped by nonmagnetic bases 2 and 3 and the hardness of the base 2 is made smaller than that of the base 3. Thus, the front shape of the head due to tape sliding shows a slide face 9 and a slide trace 10 and the wear of the base 2 is larger. The contact between the head and tape is improved at the intake of the helical scanning and the envelope of the head reproduction output is improved.

Title: Composite type magnetic head
Inventor: ABE MITSUHARU
IPC: G11B5/60
Filed: 1988-10-18
Abstract: PURPOSE:To equalize the floating quantity of left and right sliding surfaces, to also equalize the electromagnetic converting characteristic of left and right magnetic gaps and to be suitable for a high density recording by making the width of the sliding surface at the inner peripheral side larger than the outer peripheral side for a magnetic head. CONSTITUTION:A pair of magnetic cores 11a and 11b is loaded and supported, and respective magnetic gaps 14a and 14b are inclined by an angle alpha in the moving direction of a slider 13, namely, in the direction mutually different to a radius direction R of a magnetic recording medium 12. The slider 13 is composed of a non-magnetic material such as a ceramic, and with non-magnetic materials 15a and 15b such as glass, the cores 11a and 11b are fixed to the slider 13. Thus, when recording is executed to the medium 12, since the record ing direction is different at a recording track Ta due to a magnetic gap 14a and a track Tb due to a gap 14b, the crosstalk can be prevented and the float ing quantities of the left and right sliding surfaces are different. Therefore, when the widths of the sliding surface of the outer and inner peripheries are Sw1 and Sw2 respectively and the floating quantity is (h), Sw2>Sw1,  h=A(Sw1/ Sw2)+B are defined. Here, A is a proportional constant and B is a constant.

Title: Magnetostrictive torque sensor
Inventor: SUNAHATA MUTSUMI
IPC: G01L3/10
Filed: 1989-10-06
Abstract: PURPOSE:To eliminate residual tensile stress, hair cracking, etc., to prevent a shaft from being broken early, and to prolong the life by forming spiral grooves which penetrate projection step parts in the width direction in their surfaces covering the entire peripheral surface of the shaft. CONSTITUTION:The projection step parts 12 which cover the entire peripheral surface of the shaft are provided in specific areas on the surface of the rotary shaft 10 and the spiral grooves 13 are formed in the surfaces of the step parts 12 while penetrating the step part surfaces in the width direction. The spiral grooves 13 and 13 formed in the projection step parts 12 and 12 are in a both- end open shape, so the concentration of stress on both the ends of each spiral groove 13 is relieved or eliminated in spiral groove formation because of working relief at both ends of the step part 12. Therefore, the spiral grooves 13 are free from the residual tensile stress, hair cracking, etc., at both end parts. Further, a working tool such as a rolling die used to work the spiral grooves 13 reduces loads exerted on both end parts of the projection which are the weakest parts by the working relief at both ends of the step parts 12.

Filed: 1986-11-06
Abstract: PURPOSE:To provide a gas insulated transformer equipped with thin magnetic shields which are easily mounted on an inner wall of a pressure container, by piling a plurality of sheets of band-shaped magnetic materials to compose the magnetic shields and bending the magnetic shields in conformity with a curved surface of the pressure container and fixing them on the inner walls. CONSTITUTION:Magnetic shields 10 are composed of a plurality of sheets of band- shaped magnetic materials 4 made of silicon steel bands piled on an inner wall of a pressure container 3 and they are bent in conformity with a curved surface of the container and pressed/fixed with bolts 6 at both their end parts. The magnetic shields 10 composed of a plurality of sheets of piled band shaped magnetic materials 4 exert reaction force 11 against their bending and are closely adhere to the inner wall of the pressure container 3 and are allowed to be fixed with the bolts 6 at both their end parts. Because the piled magnetic materials are not required to adhere to themselves and besides because molding in conformity with the curved surface is unnecessary, manufacturing processes are simplified and reduction in cost can be performed. Since the number of the bolts 6 is much decreased, a cross sectional area of a passing magnetic flux can be increased and the thickness of the magnetic shields 10 can be made small.
