Title: Method for restoring and reutilizing tool for rolling
Inventor: UCHIDA HIDE
IPC: B21B25/00
Filed: 1985-07-10
Abstract: PURPOSE:To reduce the consumption of a high-Mo tool for rolling a seamless steel pipe by subjecting the tool which is worn or damaged after the tool is once used for rolling to surface build-up with a material consisting of the same components and reutilizing the restored tool. CONSTITUTION:The tool for rolling to be restored is assumed to be a plug 1 which consists of an alloy contg. >=70% Mo and is worn or damaged after the tool is once used for rolling. The Mo powder 2 is packed to the surface of the plug 1 and the entire part is subjected to a sealing treatment in a steel plate capsule 3; thereafter, the plug is subjected to diffusion joining by hot hydrostatic molding. Plasma spraying and high energy beam welding are applied to the build-up restoration as necessary. The costly tool for rolling is thus restored and reconditioned, by which the consumption of the tool is reduced.

Title: Semiconductor laser beam splitting device
Inventor: MIYAGAWA ICHIRO
IPC: G11B7/135
Filed: 1986-06-26
Abstract: PURPOSE:To split a light beam in an exact ratio by making a light beam emitted from a semiconductor laser incident on a polarizing beam splitter, fetching a light beam whose polarization direction is uniform, and furthermore, making this light beam incident on a half mirror to split it. CONSTITUTION:A polarized light beam splitter 5 allows a light beam polarized in the direction parallel to a joint surface 3a of a semiconductor laser chip 3 to transmit through, and reflects a light beam polarized in the direction vertical to the joint surface 3a, among the incident light beams. The light beam which has transmitted through the beam splitter 5 is made incident on a half mirror 6 which has been provided on an optical bath. This mirror 6 reflects a part of the incident light beams, and allows the remaining light beams to transmit through, and splits the light beams into two light beams in a desired ratio thereby. The light beam which is made incident on the mirror 6 is divided into two pieces of light beams in an exact ratio by the mirror 5, irrespective of the light quantity of the incident light, because the polarized light direction is uniform. Accordingly, for instance, when a photodetector 7 is provided on an optical path of the light beam which has been reflected by the mirror 6, the light beam which has transmitted through the mirror 6 can be monitored exactly by its reflected light.

Filed: 1990-06-08
Abstract: PURPOSE:To attain de-interleave processing with use of a single RAM and to simplify the constitution by utilizing a transmission period of a header data at the top of one frame to read a digital data written in the RAM. CONSTITUTION:The digital data of a RAM 1 is read by utilizing the transmission period for a framing code FC and a mode control code MC being a header data. That is, a CPU 8 controls an address changeover circuit 10 for the transmission period of a digital data such as a voice data or a character data to select write address from an address generating circuit 9 and to write the digital data to the RAM 1 so as to form an original code string and controls the address changeover circuit 10 for the transmission period of header data of a succeeding frame to select a readout address from an address bus and to read the digital data by 34 packets in the RAM 1 at high speed. Thus, the transmission period of the header data at the head of one frame is used to read the digital data written in the RAM. Thus, deinterleave processing is attained by using a single RAM to simplify the constitution.

IPC: H03M7/42
Filed: 1979-11-20
Abstract: PURPOSE:To avoid the decrease of encoding efficiency, by changing the Huffman code to a digital signal when correlation is present between sample points, depending whether there is a change in the polarity of signal between one sample prcedent point and present sample point or not. CONSTITUTION:The input signal on a signal line 451 is input to a circuit 400, and an output 1 is made on an output line 452 if the sign of positive or negative is changed and the output is fed to a control circuit 402. When the output 1 is made, the control circuit outputs 0 to the output line 454 during the clock and outputs 1 afterward, and if output 0, 1 is output on the output line 454. On the other hand, the signal on a signal line 451 is converted into an absolute value at an absolute value conversion circuit 401 and output on a signal line 453 and input to a Huffman encoding circuit 403. Further, when the signal line 454 is at 1, the Huffman code is output on a signal line 455 in synchronizing with the clock, and if 0, no signal is output. At the multiplexer 405, either the output of change sign production circuit 404 or that of the circuit 403 is selected with the content of the signal 454, and if the sign is changed, the change code is added to the Huffman code of absolute value.
