Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a variable resistance circuit with two terminal resistor characteristics which satisfies any condition of being simple and compact circuit configuration with high resolution and high accuracy and can electronically set inter-terminal resistance at any arbitrary value. SOLUTION: An active for-terminal component A (with a transfer function G) has a linlar input/output voltage relation, wherein terminals T1 and T2 are difined as input terminals, and terminals T3 and T4 as output terminals, and a reference resistor Rref is connected between the input and output terminals T1 and T3 , while the input and output terminals T2 and T4 are short-circuitted with a reference potential. When an input voltage V is impressed across the input terminals T1 and T2 of the for-terminal component A, an output across the output terminals T3 and T4 is GV, while a voltage across Rref is (V-GV), and an input current I becomes (V-GV)/Rref. Since an equivalent resistor Re between the input terminals T1 and T2 can be defined as V/I, the equivalent resistor Re forms the 1/(1-G)-times equivalent resistor of the reference resistor Rref.  In this case, the transfer function G is set at any arbitrary value by a variable digital setting input value and the desired equivalent resistor is formed.

If the radiation level abnormally rises, the alarm lamp and alarm horn of the alarm 19 are operated. A diagnostic part 37 diagnoses whether the opera tion of each detector 1 is normal at a predetermined cycle and, if the opera tional abnormality of any detector 1 is detected, the reading of the detecting signal from the operationally abnormal detector is stopped. At the same time, the normal operation lamp of the alarm 19 is put out and the operation abnor mal lamp thereof is lighted. By this method, the worker can confirm the opera tional abnormality of the detector at the site.

Title: Activating method of alkaline storage battery
Inventor: OTSUKI KOZO
IPC: H01M4/32
Filed: 1992-07-31
Abstract: PURPOSE:To heighen the use efficiency of a positive pole active material and at the same time improve the capacity of a battery by properly reacting a metal cobalt powder which is added to a nickel positive pole with a nickel oxyhydroxide. CONSTITUTION:After a storage battery is assembled, the storage battery is left until the positive pole potential becomes the potential equivalent to the equilibrium potential of Co/Co(OH)2 and then a first charge and discharge is carried out. Consequently, nickel oxyhydroxide which is added to the positive pole accelerates oxidation of metal cobalt powder to cobalt hydroxide. Since the battery is left until the positive pole potential becomes the potential equivalent to the equilibrium potential of Co/Co(OH)2, the metal cobalt powder becomes susceptive to preferential electrochemical oxidation. During the first charge of the storage battery, the electro-chemical oxidation reaction of the metal cobalt powder thus proceeds surely and the use efficiency of the metal cobalt powder is improved and the active material is activated. As a result, the use efficiency of nickel active material is heightened and battery's property, especially, battery's capacity is improved.

Filed: 1988-08-18
Abstract: PURPOSE:To improve more the code rule error detection accuracy by detecting an error in a preceding bit to a 'B' bit of a specific replacement pattern if the said preceding bit is in error. CONSTITUTION:A signal detected by a specific replacement pattern detection means 30 is fetched by the 1st code rule error detection means 70 and the 2nd code rule error detection means 80 and the 1st code rule error detection means 70 monitors whether or not the signal takes place alternately to both polarities and if the signal is not generated alternately, it is detected as an error signal. On the other hand, the 2nd code rule error detection means 80 monitors whether or not a preceding bit to a specific replacement pattern 'B00V' is opposite in the polarity with a pattern 'B' and the level is logical 1, and in case of the pattern '0B00V', it is regarded as a code rule error, the error signal detected by the 1st code rule error detection means 70 and an error signal not in compliance with the code rule because of the addition of other pulse are subject to logical operation and the result is set via an error signal output means 90 as a code rule error output. Thus, the error detection accuracy of the specific replacement pattern is much improved.

Filed: 1985-09-18
Abstract: PURPOSE:To obtain information from many information sources with one slave machine by discriminating automatically a signal for pager serviced at various modulation speeds. CONSTITUTION:Only a signal having a preliminarily determined frequency band is amplified selectively by a front end 2 and is demodulated by a demodulating circuit 3.
