Title: Magnetic recording device
Inventor: KONDOU OSAMU
IPC: G11B15/02
Filed: 1980-10-31
Abstract: PURPOSE:To confirm a driving fault of a magnetic tape, by detecting an optical variation point of the magnetic tape when starting the tape, and operating an information means when its detection signal is not outputted within a prescribed time. CONSTITUTION:When a control driving signal is outputted to a magnetic tape device 3 and a timer circuit 6 through a control interface 4 from a CPU1, a magnetic tape 13 is rotated and the timer circuit 6 is operated. Subsequently, when a tape mark such as silver paper, etc. provided on the tape 13 has been detected by a tape mark detector 18, the timer circuit 6 stops its operation. As a result, the CPU1 executes recording and reproducing in accordance with a counting value of a block counter 5. On the other hand, unless the detector 18 detects the tape mark within a prescribed time, an error signal is outputted from the timer circuit 6, and the CPU1 operates an alarm 2. In this way, a driving fault such as tight fit, etc. of the tape 13 is confirmed.

Title: Current interruption detector for power converter
Inventor: OOMAE TSUTOMU
IPC: G01R19/00
Filed: 1981-09-30
Abstract: PURPOSE:To increase the reliability of detection signals, by discriminating continuity and discontinuity of a motor current and obtaining a specified output signal only at discontinuity. CONSTITUTION:A motor current id detected at a detection DC current transformer 3 via a power conversion circuit 1 becomes a current Id via a filter 4 and an output voltage Eda via a function generator 5 respectively. On the other hand, a DC voltage ed is smoothed at a filter 2 to be Ed. A comparator 6 compares the Ed with the Eda, and an otput (g) is taken as ''0'' level when Ed>Eda by regarding the id as continuous and an output (g) is taken as ''1'' level when Ed<= Eda by regarding the id as discontinuous. Further, the id is taken as a current interruption detecting signal (f) at a current interruption detecting circuit 8. Thus, a signal (h) can be obtained, only when the signals (f) and (g) are coincident and the current interruption is indicated.

Title: Seismic isolator of building
Inventor: FUJIWARA YUKIO
IPC: F16F15/04
Filed: 1995-06-21
Abstract: PURPOSE: To enhance the safety of a structure by laying out alternately a plurality of metallic plates and a plurality of elastic plates and thereby constituting a seismic isolator and a weir which forms a contact surface having a specified slope on the outer edge of the seismic isolator. CONSTITUTION: A weir 6 is installed around a seismic isolator 3, thereby constituting a building seismic isolating device. The weir 6, when it receives a horizontal force and reaches a specific amount of displacement, is arranged to provide a contact surface 8 which comes in contact with the outside surface of the seismic isolator 3. The contact surface 8 is formed in a conical shape. The weir 6 installed around the seismic isolator 3 shows small rigidity when the seismic isolator 3 is subjected to shear displacement over its full length in the early stage of displacement. However, after the displacement of the seismic isolator 3 further proceeds and comes in contact with the contact surface 8 of the weir 6, such an area, which is placed in contact with the weir 6, is immune to shear displacement.  Therefore, only such a non-contact area proceeds with displacement, thereby increasing the rigidity of the seismic isolator 3.
