Title: Thermally-actuated switch
Inventor: TSUJI TAKEO
IPC: H01H37/54
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a thermally-actuated switch with an airtight container having no influence from a fluctuated electric current passing through it. SOLUTION: This thermally-actuated switch 1 has an airtight container composed of a container 2 and a lid plate 3. A lead terminal pin 5 provided with a fixed contact part 6 is airtightly insulated and fixed to the lid part 3. A movable plate supporting body 7 to be rigidly combined with one end of a movable plate 8 is conductively secured to the lid plate 3. A movable contact 9 is inserted in a through hole provided on the free end of the movable plate 8 and in a through hole bored in the drawing center of a thermally- actuated plate 10. The movable contact 9 is fixed to the movable plate 8, and holds the thermally-actuated plate 10 by loose fitting between the head part 9A of the movable contact and the movable plate 8, in order to interlock the movable plate with an action of the thermally-actuated plate.  Since an electric current does not practically pass through the thermally-actuated plate, even if it is attached to an appliance having a fluctuated electric current, a circuit can be cut off at a designated temperature.

IPC: G06F17/30
Filed: 1991-10-25
Abstract: PURPOSE:To unnecessitate a sort processing in the case of retrieving the export/ import sums of articles by countries and displaying those amounts in a descending order. CONSTITUTION:A date base 13 for numerical value defines an opposite side country code, article code and export/import code as first retrieval keys and has amounts and sums at plural time points as data to be retrieved. A data base 12 for rank defines an article code, export/import code and time point as second retrieval keys and stores the opposite side country codes in order of the export/import sums at the time point showing the article shown by the article code as data to be retrieved. A retrieval system 16 retrieves the data base for numerical value with the first retrieval keys in the order of the opposite side country codes having the higher export/import sums obtained by retrieving the data base for rank with the applied second retrieval keys and displays the obtained amounts and sums to a user 17.

Title: Line restoring circuit
Inventor: NAGATO TAKASHI
IPC: H04M7/00
Filed: 1986-11-26
Abstract: PURPOSE:To eliminate a large capacitance capacitor and to miniaturize a circuit by connecting both a relay coil and a relay driving circuit to a primary power source directly connected to a station power source at a line restoring circuit provided in a carrier terminal station. CONSTITUTION:If a secondary power source V2, is shut down in a time during response, a timer 9 is activated to turn on a transistor 71, and a relay 4 is driven. Thus a relay contact point 10 is opened to isolate the line. During that isolation, the timer 9 counts a time by 500ms-1sec. At the end of counting, a signal from the timer 9 drops the output voltage of a comparator 72 to turn off the transistor 71. Thus the relay 4 is deenergized to close the relay contact point 10, and a blocking signal is transmitted to restore the line.
