IPC: H04M1/274
Filed: 1987-05-29
Abstract: PURPOSE:To avoid the misrecognition due to the noise and to secure the sure calls by carrying out the calls based on the voice recognizing result of a voice recognizing means which recognizes the voices shown by the sound signals led out onto an unbalance line via a valance/unbalance conversion means. CONSTITUTION:The sound signals supplied from a band-free mike 494 and a handset mike 496 are converted into the signals set on a balance line 351a by the U/B converters 412 and 421 and supplied to voice recognizing part 350a via the line 351a. Then these sound signals of the part 350a are converted into the sound signals set on an unbalance line 351b by a B/U converter 351 and used for the part 350a. As a result, the in-phase noises set on two lines forming the line 351a are eliminated by the converter 351. Thus it is possible to prevent the malfunctions due to misrecognition and to improve the recognition rate.

Title: Automatic steering controlling method
Inventor: OKADA MINORU
IPC: B62D1/28
Filed: 1984-06-28
Abstract: PURPOSE:To improve both the response property and stability of an unmanned carrier car, by establishing the relation between the size of a steering command to the unmanned carrier car to the deviation between its running course and the car in proportion to the (n)-th (n>1) power of the deviation and not in linear proportion. CONSTITUTION:When a target value is set at epsilon0=0 which makes the deviation from a running course to zero, the position P of an unmanned carrier car at an optional moment is given to a steering controller 5 as a deviation epsilon from the running course through a feedback element 3 and comparator 4. The steering controller 5 has a transmission function ¦S¦=K2, epsilon<n> (n>1) against the deviation epsilon and outputs a steering command S. A steering driving device 6 drives a steering device 7 in accordance with the steering command S and corrects the car position by transmitting the drive to the unmanned carrier car. By making the steering command S proportional to the (n)-th power of the deviation epsilon (n>1), the response property when the deviation epsilon is large and the stability when the deviation epsilon is small are improved. It is practical to set the (n) at 2 (n=2) so as to obtain ¦S¦=K2epsilon2.

IPC: B23K9/04
Filed: 1979-10-22
Abstract: PURPOSE: To prevent the formation of fine cracks by performing build-up welding of copper while controlling the temperature rise of stainelss steel by flowing a cooling medium within a vessel mounted to the stainless steel.  
     CONSTITUTION: A vessel 2 for flowing cooling water is watertightly mounted to a stainless steel 1 by way of O-rings 3. Here, 4 in the figure denotes the inlet for cooling water, 5 the outlet for cooling water, 6 the inlet of cooling water from the outlet 5, and 7 the outlet of this cooling water, respectively. Next, in the case of performing build-up welding of copper, cooling water is flowed in the vessel 2, after which the build-up welding of the copper is carried out to form an alloy layer 9 on the build-up weld zone 8. As a result, the steel 1 becomes difficult to be melted by the welding arc; therefore, penetration becomes shallow and the alloy layer 9 of the copper and the steel 1 becomes thin. Since the temp. of the steel 1 becomes approximately constant, the temp. difference at the heating and cooling is relieved, thus the sound padded part of less cracking by stress or less surface oxidation of the padded copper owing to heat is obtained.
