Title: Method for testing and evaluating metal fatigue acceleration
Inventor: SHINGUUHARA SHIYOUZOU
IPC: G01N3/32
Filed: 1989-02-06
Abstract: PURPOSE:To detect the occurrence of a defect for before a wire breaks down and to make it possible to shorten the time of evaluation by detecting the gradual decrease in electric resistance of a specimen. CONSTITUTION:A specimen 10, a DC source 11 and a voltage amplifier 12 are provided in an electromagnetically shielded box so as not to receive the effect of external noises. A resistor 14 (resistance value R) is connected to the sample (resistance value r) in series so as to remove the fluctuation in current value due to the minute fluctuation of the sample. The output of the amplifier 12 is inputted into a power spectrum analyzer 15. The power spectrum intensity with respect to the number of vibrations is measured in order to analyze the fluctuation in voltage corresponding to the degree of fatigue of the sample. In general, wire breakdown defects of metal wirings and the like are caused by the occurrence and the growth of void cores due to the diffusion and concentration of lattice defects. The formation of the void core appears as the gradual decrease in resistance. Therefore, when the fluctuation in electric resistance is checked and the gradual decrease in resistance fluctuation is detected, the formation of the void core can be detected.

Filed: 1982-02-22
Abstract: PURPOSE:To reduce the noise sounding without utilizing additional circuits at all making optical coupling as highly efficient as that of single mode laser by a method wherein an external resonator is provided near semiconductor laser element to fix vertial mode. CONSTITUTION:With specified voltage impressed, the laser beams 6 are emitted from the output surfaces above and below the tip 5 and the upward laser beams 6 advance outside cap 9 through wind glass 8 to irradiate audiodisc surface while the downward laser beams 6 input into light receiving element 7 to be output-monitered partly reflected by the surface returning to the laser element 5 again.

Title: Obstacle detection device
Inventor: TAKIGAWA YOSHIFUMI
IPC: G05D1/02
Filed: 1994-02-24
Abstract: PURPOSE:To enable a vehicle to be accurately distinguished from shoulder protection without calculating a frequency band width by providing a judging portion in a device which measures relative velocities and distances based on transmitted and received FM-CWs. CONSTITUTION:FM-CWs are transmitted as emitted waves, and the received waves reflected by a reflecting object and the waves emitted are mixed to produce a beat signal. A peak frequency is calculated from the result of the frequency analysis of the beat signal, and the deviation of the peak frequency from the adjacent peak frequency is calculated. The lowest level between the peak frequency and the adjacent one is calculated, and the deviation is correlated with the lowest level. Thereby an obstacle is identified as either shoulder protection or a vehicle. Obstacle detection is thus made possible which is more resistant to noises, especially during travel along a curve, than it would be if analysis of a frequency band width is carried out for identification of the obstacle as either shoulder protection or a vehicle.

Title: Electrode biasing device for biosensor
Inventor: SUGIYAMA RYUICHI
IPC: G01N27/30
Filed: 1987-02-06
Abstract: PURPOSE:To exactly measure an object material by biasing a current/voltage converter at the time of applying a forward bias to an electrode and reverse bias thereto by the current/voltage converter. CONSTITUTION:The electrode 4 is forward biased when a cathode side electrode 4b is grounded by outputting a voltage 0V from a reverse bias supplying terminal 5 in the case of measuring the object material. The current corresponding to the quantity of the material formed or annihilated by the reaction of the fixed enzyme of an immobilized enzyme film and the object to be measured, therefore, flows in this state from the anode side electrode to the electrode 4b. Since a diode 3 is held non-conducting at this time, the voltage signal superposed with an offset voltage by the forward bias on the voltage signal proportional to the current is taken out of the output terminal 1c of an operational amplifier 1 for current/voltage conversion. Refreshment of the electrode is executed simply by outputting the voltage higher than the partially divided voltage conversely from the terminal 5. The exact measurement is thus permitted.
