Title: Method for adding calcium or the like to molten steel
Inventor: KITAGAWA SHUZO
IPC: C22C33/04
Filed: 1985-02-01
Abstract: PURPOSE:To improve the yield of a free cutting component added to molten steel by filling granules of the free cutting component such as Ca or Pb into iron capsules so as to regulate the apparent specific gravity of the capsules to >=8 and by adding the filled capsules to molten steel. CONSTITUTION:Powder or granules of Ca, one or more among Pb, Bi and Te, or an alloy thereof as a free cutting component are filled into iron capsules so as to regulate the apparent specific gravity of the capsules to >=8. The filled capsules settle in molten steel because the specific gravity is higher than that of steel. The capsules are added to molten steel.

Title: Dc-current detecting apparatus
Inventor: MATSUDA SATOSHI
IPC: H02M7/48
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To obtain a DC-current detecting apparatus by which a DC portion is detected with high accuracy and at high speed by a method wherein the instantaneous value of a digitally converted output current is integrated at every cycle of a system voltage and the output of an integrating part is held for one cycle of the system voltage. SOLUTION: A current detector 102 detects an instantaneous current value which is output to the output system 108 of an inverter 101. An A/D converter 104 receives the analog output signal of the current detector 102 so as to be converted into a digital value. A zero-crossing detector 103 detects the zero- crossing point of the voltage of the power system 108 so as to output a signal at every zero phase. An integrating part 105 integrates a current signal converted by the A/D converter 104 for one cycle portion of the power system 108 according to the signal of the zero-crossing detector 103. A holding part 106 holds the output of the integrating part 105 for one cycle portion of the power system 108. The integrating part 105 clears an integrated value so as to start an integrating operation at a next cycle.  Consequently, a DC portion can be detected without being affected by a change with the passage of time and by a temperature drift and at the cycle of a system voltage.

Title: Washing device for scale
Inventor: SAO TOSHIO
IPC: C23G3/04
Filed: 1992-02-03
Abstract: PURPOSE:To safely and efficiently remove the scale sticking to the inside surfaces of a circulating line by passing washing liquid through a cation exchange resin column and then passing the washing liquid to a mixed bed column contg. a cation exchange resin and an anion exchange resin while circulating the washing water. CONSTITUTION:A replenishing water tank 1, a circulating pump 2 and a wash 3 are connected by pipings 4 to constitute the circulating line. The strongly acidic cation exchange resin column 5 is disposed at the piping 4 on the upstream side of the wash 3 of this circulating line and the mixed bed column 6 on the downstream side in such a manner that these columns can be bypassed respectively by valves 5a, 6a. The strongly acidic cation exchange resin and the strongly basic anion exchange resin are mixed and packed into the mixed bed column 6 mentioned above. The replenishing water in the replenishing tank 1 is passed by the circulating pump 2 to the cation exchange resin column 5, where the anions of neutral salts such as NaCl, in the replenishing water are exchanged with H<+> to form acids, such as HCl to form the washing liquid. The scale sticking to the inside surface of the pipings 4 is thus dissolved away. The washing liquid is thereafter passed into the replenishing 6 where the cation and the anions are removed to form the pure water.

Title: Semiconductor laser
Inventor: UENO SHINSUKE
IPC: H01S5/00
Filed: 1984-02-03
Abstract: PURPOSE:To enable large photo output oscillation due to basic lateral mode oscillation by oscillation at low threshold values and high efficiencies by a method wherein the titled device is so formed that the interface between a narrower stripe region and a wider stripe region comes to a total reflection angle to laser oscillated beams. CONSTITUTION:The first guide layer 12 is formed in adjacency to an active layer 13. The light of the active layer 13 propagates by partial ooze-out to the guide layer 12, and the laser oscillated beam at the center region propagates through the active layer and the guide layer, but most of the light of the active layer 13 propagates by ooze-out into the guide layer 12 because the layer 12 is thick in the neighborhood of both reflection surfaces. The outside of the stripe region serving as the resonator is filled with a high specific resistance layer, and particularly both ends of the second clad layer 14 are filled with the fourth clad layers 15 different in conductivity type and high in specific resistance; therefore, injected currents are efficiently contributed to oscillation. Light propagates in the longitudinal direction in the resonator without receiving loss, and carriers little leak, resulting in laser oscillation of low threshold value and high efficiency.

Abstract: PURPOSE:To reduce the load of a document producer by converting documents into models and producing automatically the paragraph end heading numbers by a machine in a document production number. CONSTITUTION:In case a new paragraph end is set in a document input mode, one of a paragraph end key 21, a next paragraph end key 22 and a receding paragraph end key 23 is pushed. Here these three keys 21-23 show the production of paragraph ends of the same level, a lower level and a higher level respectively. Thus a new paragraph end group number is produced with push of those paragraph end keys and with reference to a paragraph end group number register 7. The register 7 is always replaced so as to hold the final group number at all times. Then the paragraph end control codes are searched up to the end of a document buffer 5 which decides the paragraph end heading number with reference to the paragraph end heading style after the paragraph end group number is decided. These processes are successively repeated to arrange the paragraph end headings of the document as a whole.
