Abstract: PURPOSE:To directly join a TiC cermet and a sintered hard alloy with sufficient joining strength without using a brazing filler metal by specifying the composi tion and grain size of the cermet and alloy, finishing the joining surfaces by grinding, laminating both materials and heating the laminate to a specified temp. in vacuum. CONSTITUTION:The TiC cermet consists of TiC 0-40mol.% Mo2C, 5-20% Ni and <=4O% TiN. The average grain size of the hard phase is controlled to 0.5-3.0mum and the lattice constant of the binder phase to >=3.56Angstrom . The sintered hard alloy consists of WC having 1.5-5.0mum average grain size and 10-35% Co, and the lattice constant of the binder phase is adjusted to <=3.57Angstrom . The quantitative ratio of the binder phase of the alloy to that of the cermet is controlled to 0.8-2.0. The joining surface is ground by a grindstone of >=#14O grain size and finished, and both materials are laminated. The laminate is heated to 1330-1350 deg.C in a vacuum of 13X10<4> to 65 Pa and kept at that temp. for 30-90min, and both materials are directly joined. The heating rate is adjusted to 2-6 deg.C/min.

IPC: B02C18/00
Filed: 1991-03-15
Abstract: PURPOSE:To provide a long serviceable cutter to cut tough fibers of empty palm nuts after their flesh is removed. CONSTITUTION:Empty palm nuts are fed into a pair of screws (12) biting one another in a housing to cut them by means of mutual biting of the screws. Then, cyclic blades (13, 14) in the form of spectacles planted on the inner wall of the housing cut them again as if emulating said performance of the screws (12), thus the apparatus is not dependent on the sharpness of the cutting edges and serviceability thereof is improved. Furthermore, empty palm nuts also can be cut under a high steam pressure while retaining the pressure at an inlet (11) and an outlet (15) of the housing. The so-cut empty palm nuts are compressed by a compressor (29) to recover the lost oil and scraps of the compression are used as fuel or fertilizer.

Filed: 1985-03-13
Abstract: PURPOSE:To compensate the offset and to improve the static accuracy by storing the operating value of the integration control output in a stable mode and adding this operating value to the operating value of proportion-integration PI control to perform the PI control. CONSTITUTION:With the improved PI control, the fixed value set previously is first read out and this value is defined as the target level to calculate the operating values of both the propertion P control and a integration I control. Then it is decided whether (t) seconds passed after the start of control. If the (t) seconds to not pass yet, both operating values of the P and I controls are added together. Then the value based on said sum value is delivered to a servo valve. While it is decided whether the memory value is set or not if the (t) seconds passed. Then the operating value of the I control obtained at that time point is set as the memory value. Then the integrated value of the operat ing value of the I control and the deviation is reset, and the operating value of the P control and the memory value stored previously are added together and delivered to the servo valve. Thus the offset compensation value is added separately from the I control in the form of the memory value.
