Title: Magnetic tape cartridge
Inventor: IKEBE MASARU
IPC: G11B23/107
Filed: 1988-05-20
Abstract: PURPOSE:To smoothly insert and take out a leader block to and from a case even at the time of repeating this operation to prevent erroneous recording and reproducing by constituting the leader block of a molded article consisting of a fluororesin and a plastic base material containing glass fibers. CONSTITUTION:A molded article consisting of a fluororesin and a plastic base material containing glass fibers is used as a leader block 18. Since the wear resistance is given to the plastic base material because a polytetrafluoroethylene as the fluororesin is mixed, the leader block 18 has the characteristic of the plastic base material reinforced by the characteristic of glass fibers and is superior in wear resistance. Thus, when initialization for the inserting force and the taking-out force of the leader block 18 is properly performed, the inserting force and the taking-out force are not changed and are stabilized thereafter even at the time of repeated use, and the occurrence of dust or the like due to the wear is reduced, and erroneous recording and reproducing due to dust or the like do not occur.

Title: Bar graph type fuel gage
Inventor: OGASAWARA SHINYA
IPC: G01F23/00
Filed: 1983-07-12
Abstract: PURPOSE:To make the display of the remaining fuel quantity accurate, by making the number of display segments to be a number, which is obtained by multiplying the number that is obtained by subtracting 1 from a specified number by integer times; when the ratio of the remaining quantity in a tank with respect to the total capacity of the fuel is made to be one over specified number at the time bar indication is EMPTY. CONSTITUTION:The remaining quantity when the display is E (EMPTY) is usually made to be 1/8 the full capacity of a tank. When the display is E-1/4, the fuel capacity corresponds to 1/8. As a result, the capacity of the fuel between 1/4-1/2, 1/2-3/4, and 3/4-FULL becomes 2/8, respectively. Then, the entire length of the display segments of a bar display device 1 is divided at a ratio of 1 with respect to the capacity of 1/8. The number of the display segments 1a with respect to the capacity of 1/8 is made to be 2. Then the bar display device 1 is constituted by the total of 14 display segments 1a. In this way, a characteristic C can be obtained, and the remaining fuel in the tank is made to agree with the bar graph display. Thus the remaining fuel quantity can be accurately displayed.

Title: Reproduction control method for video cd and device therefor
Inventor: HAYASHI HIDEKI
IPC: H04N5/765
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To control whether the reproducing of a video CD is right or wrong, based on the information being in the TOC area of the video CD stored in a memory part. SOLUTION: A video CD whose reproduction is desired is loaded on a disk drive (S26), the control information being in a TOC area are read out to be stored in a memory part (S27). A reproducing request from an input part is judged (S28) and when the reproducing of the video CD is requested (Yes), the total reproduction time of the loaded video CD is compared with the total reproduction time of a reproduction inhibition video CD preliminarily stored in a storage area (S29). Whether the total reproduction time stored in the storage area which coincides with the total reproduction time of the video CD exists or not is judged (S30). When total reproduction times do not coincide in the processing 30 (NO), a reproduction is permitted and a reproducing processing is performed.  Moreover, when they coincide in the processing S30 (YES), a stopping processing is performed by judging the loaded video CD to be the reproduction inhibition video CD. Furthermore, when there is not the reproducing request in the processing S28 (NO), the stopping processing is also performed. Thus, the reproducing of a specific video CD by a third person can be prohibited.

Inventor: EBINA KOICHI
IPC: G05D1/02
Filed: 1988-05-24
Abstract: PURPOSE:To surely detect a ferrite signpost by setting a center detecting coil between the right and left detecting coils. CONSTITUTION:The output signals Lb, Rb and Cb are rectified by the rectifiers 22, 32 and 62 and gain the same phase respectively. The signal Lb of a left detecting coil 2 is added to the signal Cb of a center detecting coil 6 by an adder 23. At the same time, the signal Rb of a right detecting coil 3 is added to the signal Cb by an adder 33. Thus the output voltage obtained at the center part between both coils 2 and 3 can be set at a high level attained by adding the signal Cb to the signals Lb and Rb. As a result, the output voltage of the center part is never dropped to a level lower than a decided level. Thus it is possible to detect a ferrite signpost 4 and to surely guide an unmanned vehicle.
