Title: Plenum length measuring instrument for nuclear fuel rod
Inventor: YAGINUMA YOSHITAKA
IPC: G01B7/00
Filed: 1986-07-11
Abstract: PURPOSE:To measure the length of a plenum without temporarily interrupting carrying by providing a boundary detecting means which detects a first boundary where the front end of a fuel rod and a coiled spring are brought into contact with each other and a second boundary where the coiled spring and a fuel pellet are brought into contact with each other. CONSTITUTION:A boundary detecting circuit 10 consists of an electromagnetic induction measuring circuit 8 and a voltage peak detecting circuit 9. A detection signal S outputted from the circuit 8 is supplied to the circuit 9, and the period from a minimum peak voltage of the signal to a maximum peak voltage is detected by the circuit 9, and the result is supplied as a boundary detection signal KS to an operation processing device 11. Thus, the signal KS falls (or rises) from the low level to the high level (or from the high level to the low level) when a boundary part A1 (or A2) reaches a coil part 7. Consequently, a plenum part PA of a nuclear fuel rod A is detected when the signal KS is in the high level.

Title: Vehicle-to-vehicle distance measuring apparatus
Inventor: TAKIGAWA YOSHIFUMI
IPC: G01C3/06
Filed: 1993-07-01
Abstract: PURPOSE:To make the detecting of a correct peak combination of modulation frequencies possible even when vehicles ahead exist in plurality by a method wherein a wave emitted with a non-modulation part is transmitted to detect each beat frequency with the analysis of a frequency from the wave received. CONSTITUTION:A modulation signal data which contains a non-modulation part at a trough part of a modulation wave from a modulation pattern memory section 11 is outputted to be transmitted with modulation 3 of a frequency. The wave received is synthesized 6 with a wave emitted A to be converted into a beat signal with a demodulation circuit 7. The beat signal is separated with a demodulation signal separation circuit 12 in frequency on the rising side and on the falling side of the non- modulation part and the modulation part based on a synchronous signal from a synchronous signal generation circuit 9 and information thus obtained is sent to a frequency analysis/signal processing section 13. The processing section 13 performs an FFT analysis of the results and combine the beat frequency on the rising side and the beat frequency on the falling side of the modulation part at random to calculate a beat frequency. When any beat frequency thus obtained coincide with the beat frequency of the non-modulation part, the combination of the peaks of the frequency is correct to calculate a speed in the combination.

Title: Microstrip line circuit device
Inventor: OOHASHI MITSUO
IPC: H01P3/08
Filed: 1982-09-18
Abstract: PURPOSE:To use a titled device even in case of a large current, by wire-bonding an Au wire which is narrower than electric conductor width of a microstrip line, to its strip line having a characteristic of high impedance. CONSTITUTION:An Au wire 4 is wire-bonded onto a microstrip line 3 for the bias. When a DC resistance portion of the microstrip line 3 and DC resistance of the Au wire 4 are connected in parallel, the composite resistance becomes low, and a voltage drop in case when a current flows is reduced. As for a microwave signal, an electric field is not concentrated on the center of the strip line 3, but is concentrated in the dielectric substrate onto both ends and the reverse side of the strip line, therefore, even if the Au wire 4 is installed onto the center of the strip line 3, no influence is exerted on a microwave signal.

Title: Safety device for lithium battery
Inventor: KOZAI SHIYOUYA
IPC: H01M50/583
Filed: 1983-09-06
Abstract: PURPOSE:To protect a lithium battery during over-current by soldering one end of a lead wire to which force is applied in such a manner as to cause it to be separated from the electrode and cutting off the circuit when the temperature exceeds the melting point of solder. CONSTITUTION:Lithium batteries 10A and 10B are installed in a case 30 with metallic members 32 and 34 interposed. An opening 36 is formed in the case 30. A lead wire 42 is used to connect electrodes 38 and 40. One end 42A of the lead wire 42 is fixed to the electrode 38 by spot welding and force is applied to the other end 2B in such a manner as to cause the other end 2B to be separated from the electrode 40 when external force is not applied to the end 2B. The end 2B is fixed to the electrode 40 by soldering against the force applied by low- molting-point solder. Because of the above constitution, the temperature rise of the batteries 10A and 10B caused by overcurrent causes melting of the low melting point solder to separate the lead wire 42 from the electrode 40 thereby cutting off the circuit. As a result, the safety of the battery can be secured without providing any thermal fuses.
