Title: Screw conveyor of earth pressure type shield machine
Inventor: MIYAZAWA HIDEJI
IPC: E21D9/12
Filed: 1994-04-15
Abstract: PURPOSE:To stably transfer earth and sand by setting the sectional area of a blade body in the part mounted on a driving shaft, and gradually reducing the sectional area as it is radially separated. CONSTITUTION:When earth and sand are transferred by a screw conveyor 13, the stress acting on a blade body 39 in first and second conveyor parts 21, 22 can be estimated as the state where an equal distribution load acts on a cantilever beam having a driving shaft 37 side as a fixed end, and the maximum stress is caused on the fixed end side of the blade body 39. The section of the blade body 39 against the stress of such a distribution is set large in the part to be mounted on the driving shaft 37, and gradually reduced as it is separated outward in the radial direction of the blade body 39, and the blade body 39 thus has a trapezoidal section according to the stress distribution. Thus, the strength of the blade body 39 is effectively enhanced to increase the earth water pressure in a cutter chamber 7. Even when the earth discharging resistance is enhanced by a plug zone part 23, the deformation of the blade body 39 is prevented, and consolidating and blocking phenomena of earth and sand can be prevented to perform a stable transfer of earth and sand.

Title: Strain detector
Inventor: IKEDA HIDEO
IPC: G01L3/10
Filed: 1989-04-22
Abstract: PURPOSE:To improve strain detecting sensitivity by providing nonmagnetic high conductive metal layers at a gap between magnetic layers and detecting coils. CONSTITUTION:Metal layers 12 and 13 comprising nonmagnetic high conductive material such as copper and aluminum are provided at the inner sides of detecting coils 8 and 9 at t coil bobbin 7 facing the magnetic layers 5 and 6. Since the metal layers 12 and 13 have the nonmagnetic high conductivity, the penetrating depth of AC magnetic flux becomes very shallow because of a skin effect. Therefore, the magnetic fluxes which are generated by the coils 8, 9 and passing the gap between the coils 8, 9 and the magnetic layers 5, 6 are forced to through the magnetic layers 5 and 6 since there are metal layers. Thus the sensitivity is improved.

Title: Roots type supercharger for engine
Inventor: HAYATANI AKIRA
IPC: F02B33/38
Filed: 1989-04-21
Abstract: PURPOSE:To prevent the rapid reverse flow of compressed air to a displacement chamber during transfer of the displacement chamber to a delivery stroke by a method wherein, in a sealing stroke occasioned by rotation of a rotor, a part of air delivered to a delivery port is slowly returned to the displacement chamber of the rotor. CONSTITUTION:In a Roots supercharger 1, through rotation of a pair of non- circular rotors 6 in a casing 3 as the rotors are in a state to be adhered to each other, a displacement chamber Ao partitioned between the casing 3 and each rotor 6 is orderly transferred from a suction stroke through a sealing stroke Q to a delivery stroke. In this case, a delivery air blow back device 15 is situated between a pressurizing passage 10 communicated to a delivery port 5 and the displacement chamber Ao. When the rotor 6 completely closes a suction port 4 communicated to an atmospheric air passage 8 of an intake air pipe 2, an on-off valve 16 of a bypass pipe 12 is opened based on an output from a position detector 17. This constitution prevents the rapid reverse flow of compressed air to the chamber Ao along with communication of the chamber Ao with the delivery port 5.

IPC: B23D19/04
Filed: 1978-08-24
Abstract: PURPOSE: To facilitate to eliminate frontal scrap or intermediate scrap by its own weight without using external force in such a way that another pair of shearing circular edges are installed in free command of rotating by staggering by the length bigger than the camber extent of the strip in the shearing moving direction to a pair of shearing circular edges.  
     CONSTITUTION: In concurrence of installing another pair of shearing circular edges 6, 8 in free command of rotating by staggering by the length l bigger than the camber extent of the strip 1 in the shearing moving direction to a pair of shearing circular edges 3, 4 with moving a frame 12 in the direction of width to precursory strip or succeeding strip 1, shearing shown with shearing line b by another pair of shearing circular edges 5, 6 is effectuated by said staggering extent l prior to the shearing shown with shearing line (a) by a pair of shearing circular edges 3, 4. By this reason, the shearing shown with 2 pieces of shearing lines do not yield sheared remainder either irrespective of the camber extent c. In consequence, the frontal scrap 9 never fails to be sheared and separated from the intermediate scrap 10, which drops with own weight, and gets cleared off.
