IPC: F02K9/64
Filed: 1993-05-18
Abstract: PURPOSE: To make continuous harmonization of cooling conditions easier by constituting the hydraulic calibration sheath that is perforated by a plurality of micro-perforations having non-uniform sizes and densities, arranging a spacer between the sheath and an outer sealing envelope, and constituting a porous wall with sintering materials of metallic beads having the size bigger than the minimum size of the micro-perforations. CONSTITUTION: For example, inside portion of a combustion chamber plays a role of nozzle, and has a porous wall 10 exerting the heat exchange. The porous wall 10 is made of sintering materials, and is provided with a hydraulic calibration sheath 20 on its outside face, the said sheath being made of a material that is proof to the cooling liquid. The hydraulic calibration sheath 20 is perforated by micro-perforations 21 having non-uniform sizes and/or densities, for example having higher densities around throat of the nozzle, so as to obtain wholesome optimization of consumption of the cooling liquid. An annular chamber supplying the cooling liquid is defined between the hydraulic calibration sheath 20 and the outside sealing envelope 40, and a spacer is interposed between the outside sealing envelope 40 and the hydraulic calibration sheath 20.  Cross-section of the annular chamber is the maximum in its top portion and it reduces toward to the bottom of dispersion section.

Title: Control method of rolling mill
Inventor: KOYAMA HIROSHI
IPC: B21B37/00
Filed: 1983-06-29
Abstract: PURPOSE:To continue operation stably in a different-speeds rolling process by controlling respective peripheral speeds of a pair of rolling rolls to the speed of a rolling material at its exit side and also the sum of the motor torques for driving two rolling rolls to a prescribed value. CONSTITUTION:Rolling is performed between rolling rolls 1, 2 which are driven by motors 8, 11 respectively. A motor control system has ACR13, ASR14 and controls in correspondence with a command of a speed setter 15. Here, the operation is performed by bringing the peripheral speed v2 of roll 2 comparatively closer to the speed V2 (where v2<=V2) of a rolling material at its exit side. A motor 8 control system has an ACR9 and performs a torque constant control by a command value tauT of a torque setting circuit 10. That is, the circuit 10 outputs a command to the ACR9 by calculating a value tauT obtained by subtracting a torque tauB generated by driving the roll 2 from a rolling torque tau required for rolling.

Abstract: PURPOSE:To shorten a designing process by performing an approximate integral operation by a boundary element method and based on the average value of flux density among the specific times of each thermal cycle and based on a 3-dimensional analysis model of a thermal cycle structure and then obtaining the temperature change of this structure. CONSTITUTION:The shape data that prescribe a thermal cycle structure are inputted to a computer by a data input means 1, and a modeling means 2 produces a 3-dimensional analysis model of a metallic model or a cooling device based on the shape data. At the same time, the conditional data that prescribe a thermal cycle of the metallic mold are also inputted to the computer by the means 1 and then added to the 3-dimensional analysis model to undergo an integral operation by an arithmetic means 3.

IPC: B65B27/08
Filed: 1992-05-08
Abstract: PURPOSE:To easily pull up a tape holder alone for removal from between a group of small paper sheaves and already wound tape by a method wherein a small paper sheaf group retaining mechanism is provided with a friction resisting body for producing frictional resistance by facial contact with the small paper sheaves being filled in. CONSTITUTION:A small paper sheaf group retaining mechanism 10 is formed into a box-like shape with an open top and consists of a moving wall 11 movable by a small paper sheaf group transfer mechanism, a holding wall 12 normally biased toward the opposite moving wall 11 by a spring member and having a sheet-like friction resisting body 12 attached to its inner surface, a reference wall 13 supported integrally with the moving wall 11 and a limiting wall 14 normally biased toward the opposite reference wall 13 by a spring member. After completion of a temporary rewinding of tape T following winding of the sheaf group with the two turns of the tape, the sheaf group retaining mechanism 10 is moved rearward of the binder by the sheaf group transfer mechanism to compress the sheaf group in the thickness direction and, at the same time, continue reverse rotation of a tape feed mechanism. In this condition, the tape is cut off and the sheaf group transfer mechanism is thereafter moved slightly forward of the binder so as to release the sheaf group from its compressed condition and reduce the frictional resistance between the sheaf group and the tape holder 30, whereby the removal of the tape holder is effected by a tape holder removing mechanism 80.

Abstract: PURPOSE:To improve the ohmic properties of an ohmic electrode while facilitating the control of the depth of a P-N junction by introducing an impurity changed into a reverse conduction type from the upper surface of one conduction type carrier multiplication layer formed onto an optical absorption layer or a carrier acceleration layer. CONSTITUTION:With a P-type region 6, Cd having a small diffusion coefficient is used as an impurity, and it is shaped in desired depth through a gas diffusion method. When Cd is employed as the impurity, a diffusion time is lengthened, thus easily controlling the depth of the P-type region 6, the depth of a P-N junction 10, then improving the yield that the P-N junction 10 is received in desired depth. Zn having a large diffusion coefficient is used as an impurity in a P-type contact region 11 and the region 11 is shaped through the gas diffusion method, and the ohmic properties of P-electrodes 8 are improved. Since the temperature of the diffusion of the latter is made lower than that of the diffusion of the former and the time of the diffusion of the latter is made shorter than that of the diffusion of the former, the depth of the P-N junction 10 formed by the diffusion of the former is not disturbed by the diffusion of the latter.
