Title: Telephone device
Inventor: IKUSHIMA TOSHIZO
IPC: H04Q3/58
Filed: 1999-08-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to exactly recognize the time spent on calling and the like even immediately after the operation time is changed by additionally outputting the information showing that the operation time has been changed when operation times in each time of the start and the end are different. SOLUTION: A daughter indicator 43 indicates the present date, day of week and time, the outside line number of a destination, the time when a call starts and the time (15 minutes) spent on calling till the present time. In this case, the time spent on calling must be an hour and 15 minutes since the time when a call starts is 2:58 a.m. and the present time is 4:13 a.m., but 3:00 a.m. of the standard time is shifted to 4:00 a.m. in the daylight saving time, because April 1 is a switchover day of operation time. Therefore, 15 minutes, the exact time spent on calling, is found by subtracting one hour further. On this occasion, a user does not know why the time spent on calling is shortened only because it is corrected and indicated and is likely to misinterpret it as a trouble of a telephone device.  For this reason, the user is informed of the correction on the basis of an operation time switchover system by indicating 'correction because of the daylight saving time: -1 h' next to the time spent on calling.

Title: Structure of composite multicore electric wire type sensor with cores having different coefficients of elongation
Inventor: WATANABE TADAYOSHI
IPC: H01B7/32
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a structure of composite multicore electric wire type sensor which can detect the progress of a landslide and cracks in the ground by utilizing such a fact that the cores of a composite multicore electric wire containing cores having different coefficients of elongation and laid along a slope are cut with time lags when the distance between fixing points becomes longer due to a crack in the ground when the structure is used for a landslide detecting system sensor which is installed to the slope for detecting landslide. SOLUTION: The cores of a composite multicore electric wire type sensor are formed by spirally winding electric wires around elastic bodies, the outside diameters of which are reduced as the elastic bodies elongate, at calculated intervals. In addition, the cores are mixed with cores, which exert peculiar elongating characteristics when the cores are worked. Therefore, the coefficients of the cores can be set freely as compared with a core composed of twisted electric wires or a single electric wire. In addition, such an electric wire that has a coefficient of elongation which is remarkably larger than that of a copper wire, etc., can be manufactured. Since thin electric wires can be used, moreover, the cores can be cut even by a small tension. Therefore, a cable, which is lighter and more flexible than the conventional cable using electric wires only can be manufactured.
