Title: Production of continuously cast billet for seamless steel pipe
Inventor: KATSUMURA TATSURO
IPC: B22D11/128
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To produce a high alloy steel having little inner surface flaw and high added value at a low cost and high efficiency by applying rolling reduction to a round cast billet with one pair of saddle rolls when continuously casting the round cast billet. SOLUTION: In the production of a seamless steel pipe by means of Mannesman piercing method, V type rolls 2, 3 are used when continuously casting the cast billet 1. Therefore, since rolling reduction is applied to four positions toward the center of the cast billet, the stress zone of compression is formed in the inner part of the cast billet, the production of porosity is reduced and the segregation is reduced and the internal quality is improved. The V type roll 2, 3 used for the rolling reduction is formed with the upper bottom surface of truncated cones mutually connected and both side surfaces of two truncated cones at the connecting parts are smoothly continued. A caliber angle δ 4 of the V type roll is set in the range of 75 deg.<=δ<=160 deg..

Abstract: PURPOSE: To perform a positive removal of unwrapped bonbon and attain a remarkable improvement of quality of a product pack by a method wherein a segmented plate is provided with a sliding guide fixed to a radial inner side of a bonbon transporting rail between receiving grippers. CONSTITUTION: A take-up wheel 1 is rotated continuously in the direction of the arrow, thereby a bonbon B is fed to an unwrapped bonbon delivery zone E-E'.

At a starting point of the delivery zone E-E', receiving grippers 2, 2' are slightly opened under a certain conditioning in which a pot-like cam 6 passes through a cam track. In this case, the unwrapped bonbon B is thrown away by a centrifugal force through between the segmented plates 10, 10' at the delivery zone E-E'. The wrapped bonbon B is transferred continuously to a delivery zone D-D' against it and the bonbon is fed out in a tangential direction.

Title: Engine-driven heat pump device
Inventor: MORI MIKIO
IPC: F25B47/02
Filed: 1990-11-30
Abstract: PURPOSE:To permit heating operation even during defrosting operation and make the switching of a four-way valve unnecessary by a method wherein a circuit, in which refrigerant, discharged out of a compressor, is conducted in the sequence of an indoor heat exchanger, an outdoor heat exchanger, a pressure reducer and a refrigerant heat exchanger upon defrosting operation, is constituted. CONSTITUTION:When frost ia adhered to an outdoor heat exchanger 8 and defrosting operation is necessitated, a first solenoid valve 18 and a third solenoid valve 20 are opened while a second solenoid valve 19 is closed. Refrigerant is compressed by a compressor 1 and enters an indoor heat exchanger 4 through a four-way valve 3. In this case, one part of the refrigerant is condensed and the condensing heat of the same is employed for room heating. The refrigerant, discharged out of the indoor heat exchanger 4, passes through a first solenoid valve 18 to enter into the outdoor heat exchanger 8 without any reduction of the pressure of the same whereby non-condensed refrigerant is condensed. The outdoor heat exchanger 8 is heated by the condensing heat and sensitive heat retained by the solution of the refrigerant in this case whereby frost, adhered to the heat exchanger 8 is molten. In this case, an outdoor fan 9 is being stopped. The refrigerant, condensed in the outdoor heat exchanger, passes through a third solenoid valve 20, the pressure of the same is reduced by a second reducer and, thereafter, enters a refrigerant heat exchanger 12 and is evaporated. In this case, the refrigerant deprives cooling water of the heat thereof and is evaporated, then, is returned into the compressor 2 again through an accumulator 10.
