Title: Detection of corrosion of container wall
Inventor: PEDORO EFU RARA
IPC: G01B7/06
Filed: 1988-12-02
Abstract: PURPOSE: To inspect the corrosion of a conductor indirectly by inducing current into the conductor and then analyzing the attenuation of the current. CONSTITUTION: The energy supply is interrupted rapidly by a transmitter 29 by attenuating pulses to an intensity 0 level rapidly in a transmission coil, thus inducing an eddy current in a covering 19 and in the inside of a pipe wall 15 and diffusing the eddy current toward the inside of each conductor in a direction away from an antenna 27 and attenuating it. Then, a receiver 31 samples a signal detected by the reception coil and sends it to a digital computer 33. At this time, the attenuation of induction current at the part of the container wall 15 is recorded over a certain amount of time, thus determining an attenuation rate for the time of the induction current and hence compensating for the record of the attenuation regarding the influence due to distance fluctuation, interpreting the compensated record to determine the thickness of the part of the container wall 15, and hence inferring whether the part of the container wall 15 is corroded or not.

Abstract: PURPOSE: To provide an electrical contact material having excellent properties by adding an aqueous solution of NaOH in high concentration to an aqueous solution of AgNO 3  in which fine grains of SnO 2  are suspended, precipitating Ag 2 O, forming a powder mixture of Ag 2 O and SnO 2 , further thermally decomposing Ag 2 O into Ag to form an Ag-SnO 2  mixture, performing compression, compaction, and sintering, and then repeating annealing.  
     CONSTITUTION: A high concentration aqueous solution of NaOH is added to an aqueous solution of AgNO 3  in which fine grains of SnO 2  are suspended. The resultant mixture is agitated sufficiently to precipitate AgNO 3  in the form of AgOH and then oxidize it into Ag 2 O grains. Subsequently, after removal of Na +  ions and NO 3   -  ions from the aqueous solution containing the Ag 2 O grains and the suspended SnO 2  grains, dehydration and drying are performed and then heating is applied up to 200-500°C to thermally decompose Ag 2 O into Ag, by which a powder mixture consisting of 84-92% Ag and the balance SnO 2  is formed. After about 0.1-1% of CuO is added to the mixture, the resultant mixture is compacted and sintered, and then modification and annealing are repeated. By this method, the Ag-SnO 2  electrical contact having excellent properties equal to those of an Ag-CdO contact can be produced.

IPC: H03L7/087
Filed: 1993-11-11
Abstract: PURPOSE:To prevent low frequency jitter from being produced in a high speed clock signal outputted from a voltage controlled oscillator. CONSTITUTION:A high speed clock signal f3 outputted from a voltage controlled oscillator 5 is converted into a low spied clock signal f4 by a frequency divider 7 and given to a pulse width conversion circuit 11, in which the pulse width of the signal f4 is increased/decreased alternately for 1/2 period of the signal f3 and the result is given to a phase comparator 8' as a signal f5. A binary signal is outputted in response to a phase difference between the signal f5 and the input low speed clock signal f2 and provides a mean voltage VX resulting from an integrated signal to a voltage discrimination circuit 12. Then a predetermined digital signal is given to a gate circuit 13 in response to the voltage VX. The circuit 13 limits the passing of the input high speed clock signals f1, f3 in response to the given digital signal to provide the signal to a phase comparator 6. The phase comparator 6 gives a voltage in response to a phase difference of the signals f1, f3 as a control voltage to the voltage controlled oscillator 5.

Title: Door closing speed adjusting valve for door closer
Inventor: WAKE MASAO
IPC: E05F3/12
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent a large change of closing time of a door even when viscosity of working oil is changed due to a temperature change by extending a diameter of an inner hole of a spool hole except for an opening hole into which a head end part of a spool shaft having a V groove is inserted. SOLUTION: A housing 20 with a built-in adjusting valve and a control shaft 30 are provided, and a V groove 31 is formed on a spool shaft 32 on a head end of the control shaft 30. When a piston in a cylinder is pressed in the left direction at the time of closing a door, working oil flows into a spool hole 24 through a filter 22. Thereafter, it enters the inside of a space 28 between a screw hole 25 and the spool shaft 32 through the V groove 31 and returns to the low pressure side of the cylinder through an oil conveying hole 27. As a cross-sectional area of the V groove 31 is small, large fluid resistance is generated, and it decelerates moving speed of the piston. An inner hole of the spool hole 24 is extended in diameter except for a small diametrical part of an opening end part into which the spool shaft 32 is inserted.  Consequently, it is possible to control speed of a fluid by section sudden change resistance without being influenced by viscosity of working oil.
