Title: Cast iron piston for internanl combustion engine and its production
Inventor: KANAZAWA TAKAAKI
IPC: C23C26/00
Filed: 1986-01-21
Abstract: PURPOSE:To simply and easily produce an inexpensive piston having excellent resistance to thermal impact and thermal fatigue by disposing Al or Si to the prescribed section of the cast iron piston and irradiating high-density energy thereto, then subjecting said section to an adequate reheating treatment. CONSTITUTION:The Al and/or Si or the alloy thereof or the alloy with Fe is disposed on the surface of the section in the piston heat part of a rough shape material for the cast iron piston where the resistance to thermal impact and thermal fatigue is required. The high-density energy such as TIG arc is then irradiated thereon from above to form the alloy layer of the cast iron and the Al and/or Si by quick melting-quick resolidifying. The alloy layer is thereafter subjected to the reheating treatment for 1min-3hr at 800-1,100 deg.C. The alloyed cast iron layer in which the Al and/or Si is incorporated at 0.1-10wt% and fine block graphite is dispersed and crystallized is thereby forming to the above-mentioned section down to >=0.2mm depth from the surface and the cast iron piston having the partially improved resistance to thermal impact and thermal fatigue for an internal combustion engine is obtd.

Abstract: PURPOSE: To secure the pleasant alarm or time signal tone by giving the melody to the alarm or the time signal.  
     CONSTITUTION: Clocking counter 3 clocks each time information via the divided 2 signal, and the clocking contents are supplied to display 5. In case the proper alarm time is memorized in memory 7, FF9 turns gate 10 on when the coincidence is obtained between the clocking time and the alarm time in order to supply both the division output and the clocking output to melody control circuit 11. Circuit 11 incorporates the ROM and thus selects in sequence the programmed scale control signals to supply them to scale frequency generation circuit 12. Circuit 12 delivers the signals produced artificially in correspondence to each scale from the reference signal and based on the control signal. Then the melody is genrated from aural output circuit 13.

IPC: H03F3/72
Filed: 1979-02-02
Abstract: PURPOSE:To avoid useless power consumption, by providing the means opening the feedback resistor of C-MOS type AC amplifier and the means fixing the input terminal at high or low level potential. CONSTITUTION:The p channel MOSFET Q3 and the n channel MOSFET Q4 are connected parallelly from the output terminal B of C-MOS type FETs Q1, Q2 to the input terminal A to form the feedback resistor and AC amplifier. To the gate of FETs Q3, Q4, mutually opposite phase signal is given from the control terminal C and the inverter I. The terminal C is connected to the gate of p channel MOSFET Q5 in which the drain is connected to the terminal A and the source is at high potential. When high level signal is given to the terminal C, Q5 is OFF and Q3, Q4 are conductive and operated as a normal AC amplifier, and when a low level signal is given, Q3, Q4 are both OFF and Q5 is operated to fix the terminal A at a high level. Accordingly, Q1 is interrupted, no power supply current flows, and when it is not used as an amplifier, useless power consumption can be avoided without interrupting the power supply.

Filed: 1993-01-27
Abstract: PURPOSE:To simply measure grounding resistance without using any auxiliary grounding rod by connecting unknown and known grounding parts of grounding resistance with a lead wire and applying current of a frequency capable of discriminating a commercial frequency through a clip type transformer. CONSTITUTION:Grounding resistance R of a grounding part 11 of a distribution line 10 is known and other grounding resistance Rx of another grounding part 21 of an independent telephone line 20 is unknown. And the grounding parts 11, 21 are connected with a lead wire 30, which is clipped with a clip type transformer 40. Current of a frequency capable of clearly discriminating a commercial frequency on the ground through the grounding parts 11, 21 is applied with one transformer 41 for constituting the transformer 40 from the lead wire 30. The applied current indicates a value inversely proportional to a resultant value composed of the grounding resistance R of the grounding part 11 and the grounding resistance Rx of the grounding part 21. Such applied current is detected with the transformer 41 and the detection value includes information of (R+Rx). Accordingly, operation is performed with a measuring device body 50 from the detection value for the purpose of measuring the value of the grounding resistance Rx.

Abstract: PURPOSE: To detect the position of corrosion point and the current flowing in the corrosion point only at high precision and at high speed, without requiring complicated pretreatment, by providing a specific electrode for measuring corrosion opposedly and closely to the surface of the metal to be measured, and moving this electrode.  
     CONSTITUTION: A probe electrode 21 is surrounded with a guard electrode 23, and they are met at the flush end. The electrode 21, by way of a current detecting device 22, is connected to the negative side output terminal of a power source 24, together with the electrode 23. When a current runs, the potential between the electrodes 21 and 23 differs by the portion of the voltage drop due to the device 22, but this potential difference is small as compared with the voltage applied to the metal piece being tested 25 and electrodes 21, 23, and, hence, may be regarded as same potential level. Therefore, the stream line of the current in the electrolyte 30 positioned between the metal piece 25 and electrodes 21, 23 resembles a stream line group 31, and the current from the part opposing to the electrode 21 on the metal piece 25 corresponding to the area of the electrode 21 flows into the electrode 21, so that the local phenomenon of the metal piece 25 may be detected.
