IPC: E02D13/02
Filed: 1982-04-14
Abstract: PURPOSE:To prevent the falling or bending of a steel sheet pile when being driven into the ground by a method in which a steel sheet pile buried to an extent that it can stand by itself is held by a connector attached to connected steel sheet piles, and under the guidance of the steel sheet pile, the connected steel sheet piles are temporarily buried and set. CONSTITUTION:A steel sheet pile 1 is temporarily buried in place to a depth at which it can stand by itself. When U-shaped fitting parts 30 and 31 are inserted into the lower end portion of a steel sheet pile 2 lifted for connection, the saw- tooth 38 of an eccentric fan-shaped part 37 is cut into the steel sheet pile 2 under the weight of a weight 41 and a connector 10 is fixed to the lower part of the steel sheet pile. Under the condition, the steel sheet pile 1 is held in a vertically movable manner by the straight portion 17 and the bent portion 18 of the connector 10, where the holding power is given by a weight 20 hung down from a rope 19 passed through the hole 21. When the steel sheet pile 2 is driven through the connector 10 under the guidance of the steel sheet pile 1, each weight is dropped on the ground surface and the connector 10 can be easily removed. If all steel sheet piles could be temporarily set, they could be driven to a given depth.

Abstract: PURPOSE:To prevent overload of an additional amplifier and to expand the dynamic range by providing a level detection means generating an output in response to an output level of a band selection means and giving an output of the level detection means to a gate-source bias circuit of an FET constituting the additional amplifier. CONSTITUTION:The voltage amplitude of a basic frequency f0 component of an input signal at the output of the additional amplifier 11 is extracted via a band-pass filter 15, peak-detection is applied via a detector 16, the detection output is stored in a capacitor 17 to cause a peak value detection output. The output signal is subjected to DC amplification via an amplifier 18 and its output is given as a source power to a bias circuit between the gate and source of an amplifier 12. Thus, the AGC operation in the additional amplifiers 11, 12 is executed by the fundamental frequency f0 component of the input signal generated in a photodetector 1 only and the gain reduction in the amplifier 12 is not caused because of the noise component based on the dark current of the photodetector when the optical input is nearly close to interruption.

Abstract: PURPOSE:To reduce waste processing cost by processing to make harmless a waste liquid containing hexavalent chromium generated in a ferrous alloy steel strip manufacturing process with various waste liquids generated in the likewise ferrous alloy steel strip manufacturing process through their mutual processing using their respective specific qualities. CONSTITUTION:Spent hydrochloric acid is added to a waste liquid 9 containing hexavalent chromium to reach the pH value <=1, using the other waste liquid generated in a ferrous alloy steel strip manufacturing process. Further, an aqueous ferrous chloride solution 8 acidified to the pH value <=1 by adding spent hydrochloric acid is added to the waste solution as a reduction agent which is prepared by adding iron scrap to the waste liquid. Consequently, the waste liquid 9 containing hexavalent chrominum whose pH value is thus adjusted is allowed to undergo a reduction process so that the oxide-reduction potential of the waste solution 9 is maintained within a range of 500+ or -10mV for a reference electrode of silver chloride. After that, the waste liquid 9 containing hexavalent chromium is neutralized using spent alkali 13 so that the pH value of the waste liquid 9 is maintained within a range of 7 to 8. Finally, the neutralized waste liquid is separated into the solid and the liquid by using a centrifuge.

Title: Switching amplifier
Inventor: SANO SHINYA
IPC: H03F3/213
Filed: 1979-05-18
Abstract: PURPOSE:To increase the efficiency of switching amplifier and the performance, by forming the circuit through the use of two pulse width modulation amplifiers. CONSTITUTION:The voltage having the waveform (a) from the input terminal 1 is pulse-width-modulated with the output of the triangle wave generator 3 at the comparator 4 to obtain the waveform (d). Further, the inptut waveform (a) is inverted at the phase inverter 2 and pulse-width-modulated at the comparator 5 similarly to obtain the waveform (e). Next, the waveform (f) subtracting the waveforms (d) and (e) is fed to the speaker load 6. Since the speaker 6 is not responded to the high frequency pulse, the audio waveform (g) similar to the input waveform (a) is obtained. The phase of the output pulse of the comparators 4, 5 is in-phase and no current flows to the comparators 4, 5 or load 6 when the input is zero especially. Thus, the efficiency at small signal input can remarkably be increased. Further, the high frequency noise at no input can be reduced.

IPC: G11B5/10
Filed: 1988-03-17
Abstract: PURPOSE:To prevent generation of a step on the magnetic medium-sliding surface of a magnetic head and to prevent the exfoliation of a thin film by fitting and fixing a spacer consisting of a nonmagnetic material having a low vapor pressure and high thermal conductivity between the circumferential edge of an aperture and the front end part of a magnetic core and forming a thin film having high wear resistance on said surface of the magnetic head thereon. CONSTITUTION:The spacer 5 consisting of the nonmagnetic material having the low vapor pressure and the high thermal conductivity is fitted and fixed between the circumferential edge of the aperture and the front end of the magnetic core 2 in the aperture of a case 1 and the thin film 10 having high wear resistance is formed on the magnetic medium-sliding surface of the magnetic head. The part of the resin 4 exposed through the aperture of the case 1 is extremely lessened as the subsurface of the thin film 10 on the medium-sliding surface of the magnetic head by the presence of the spacer 5 and the adverse influence by generation of gases from the resin 4 at the time of forming the thin film 10 is obviated. The film formation is thereby well executed with the high adhesive strength. The surface of the spacer 5 is hardly evaporated at the time of the film formation by forming the spacer 5 of the material having the low vapor pressure. In addition, the heat at the time of the film formation is escaped by the high thermal conductivity of the spacer 5 and the generation of the step by the heat is prevented.

Title: Cathode-ray tube
Inventor: TAMURA KATSUYOSHI
IPC: H01J29/88
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To easily form an electrode for relieving an electric charge as a current to a tele-panel, only at the front face of which a transparent conductive film (ITO film) and a reflection preventive film (AR film) are formed sequentially by forming a capacitor in the periphery of the panel with an insulating film held therebetween, and grounding the circuit of the capacitor. SOLUTION: An electrode 4 made of conductive substance in close contact with an AR film 3 is disposed at the periphery of a tele-panel 1 where image observation cannot be prevented. An electric charge which is electrically charged via a capacitor interposed between the electrode 4 and an ITO film 2 is relieved as a current. Consequently, part of the AR film 3 formed on the ITO film 2 is removed, thus dispensing with complicated work such as disposition of the electrode 4 so as to remarkably facilitate an electrode forming process.  Furthermore, if graphite having a small particle diameter is used as the conducive substance dispersed in conductive paste which is used in forming the electrode 4, the conductive particles intrude into pin holes of the AR film 3, thus achieving electric conduction between the electrode 4 and the ITO film 2 so as to discharge the electric charge of the capacitor.
