Title: Surge absorption element
Inventor: KUBO MASAO
IPC: H01T4/12
Filed: 1987-09-26
Abstract: PURPOSE:To obtain a surge absorption element which is free in selection of its electrode materials and small in the quantity of its components and high in its productivity, by surrounding a pair of discharge electrodes with a cylindrical insulating member which serves as a spacer and next covering both end openings of the cylindrical member with metallic covers which serve as drawing electrodes. CONSTITUTION:A pair of discharge electrodes 1, 2 are made to face each other with a space S in between, and the periphery is surrounded with a cylindrical member 3 made of an electrical insulating material. A flange part 11 of the electrode 1 is put on one end surface of the cylindrical member 3, and a peripheral part of the electrode 2 is put on the other end surface, and the cylindrical member itself serves as a spacer. Both end openings of the cylindrical member 3 are surrounded with metallic covers 4a, 4b, and the peripheral parts of the covers are fixed with the cylindrical member 3 and their central parts are made in contact with both the electrodes to serve as drawing electrodes. Since this surge absorption element is formed without a necessity of brazing or the like, selection of the electrode material is rendered high in its degree of freedom. The surge absorption element can be obtained with high productivity because the quantity of its components is small.

Title: Deteriorated state detecting device for resistive junction electrode
Inventor: MIYAJI TOSHIHISA
IPC: G01N27/20
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To detect the deteriorated state of a resistive junction electrode resulted from the fixation of a plating material such as solder by detecting the peak voltage generated between resistive joined electrodes, and judging the deterioration on the basis of this peak voltage. SOLUTION: The voltage generated between resistive junction electrodes 24, 26 is sampled every prescribed time. The peak voltage Vpi in the process of resistive junction is compared with a preset peak voltage maximum value determined as a threshold Vh, and when Vpi>Vh is not established, it is judged that no abnormal peak voltage Vpi is generated in welding. When Vpi>Vh is established, it shows the generation of abnormal Vpi, and processing for measuring the frequency of Vpi detection and adding the Vpi exceeding the threshold to determine an accumulated sum Vt is performed. In case of Cn>Ch where Cn showing the frequency of Vpi detection exceeding Vh exceeds a threshold Ch, it is judged that the electrodes 24, 26 are already deteriorated and needed to maintain. When Cn>Ch is not established, it is judged that no maintenance is needed.

Title: Detecting device for rotating position
Inventor: ICHIKAWA WATARU
IPC: G01B7/00
Filed: 1984-11-20
Abstract: PURPOSE:To improve detection accuracy still more by the multiplier effect of the magnetic reluctance variation by the displacement of a magnetic substance part and the magnetic reluctance variation corresponding to the eddy current loss by the displacement of an electric conductor part. CONSTITUTION:The more the electric conductor part 2b is in the state of facing the end faces of stator pole parts 1A-1D, the more the eddy current is flowed into the part 2b by which the magnetic reluctance of a magnetic circuit passing through the pole parts facing the part 2b is increased. On the other hand, in the state that the pole parts 1A-1D face the part 2b, a gap between the pole parts and the magnetic substance part 2a of a rotor part 2 is a maximum and the magnetic reluctance of the magnetic circuit passing through the pole parts is relatively increased. Accordingly, the magnetic reluctance is multiplicatively increased and a level of the induced voltage of secondary winding W2 is multiplicatively attenuated. Then, as the part 2b is separated from a certain pole part 1A-1D, the gap between the pole part and the part 2a is shortened and the magnetic reluctance is reduced. Then, when the gap between the pole 1A and the part 2a is a minimum, the magnetic reluctance becomes minimum and the level of the induced voltage of the winding W2 of the pole 1A becomes maximum.

Title: Line switch control system
Inventor: YONEMITSU JUNICHI
IPC: H04L1/22
Filed: 1984-11-19
Abstract: PURPOSE:To allow a line switch section to switch a line by allowing a switch decision section to supervise always a transmission signal and stopping a signal output transmitted through the line or modulation by a signal operating section if it is decided that an abnormality takes place in the line. CONSTITUTION:If an abnomality takes place to a transmitter 1, a signal operating signal is transmitted from the switch decision section 2 to the signal operating section 3. The signal operating section stops the transmission signal or stops modulation and locks mark/space of the digital signal and the result is transmited to a transmission line 7. When a signal representing the stop of transmission signal or stop of modulation and locking of mark/space in a digital signal is inputted to a switching signal detection section 4, the section 4 informs an abnormal transmission line to the line switch 5. The line swich 5 switches the line and transmits a signal from a signal line 9' to transmission line 8. If a transmission line 7' is abnormal, the transmission line is switched similarly.
