IPC: G11B21/12
Filed: 1988-07-26
Abstract: PURPOSE:To prevent a medium from being damaged by a magnetic head carriage by reducing an impact force between a magnetic head and the medium at the time of loading the medium by the spring force of a load spring and a hinge. CONSTITUTION:An appropriate load is applied on a B carriage 10 by the load spring 16 when the medium 15 is loaded, and the state of a strut 4 can be maintained stably by engaging the tip part of a lug 6 with a step part 4a at the lower front of the strut 4. Also, when the medium 15 is ejected, the B carriage 10 is expanded widely, and the engagement of the tip part with the step part 4a of the strut 4 is disengaged by pressing the side part of the lug 6 by the front part of a lever 11 at that time, and the strut 4 is rotated by the reaction of the load spring 16. When the medium 15 is loaded again in this state, the B carriage 10 is returned to its original position by the restoring force of a spring 7, and when the magnetic head 9 is brought into contact with the medium 15, the medium 15 can be prevented from being damaged by the elastic buffering function of the load spring 16 and the hinge 12.

Title: Semiconductor module and power conversion device
Inventor: SATO SHINJI
IPC: H02M1/00
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor module and a power conversion device with good transient current balance, even when semiconductor elements with a variation in threshold values are connected in parallel. SOLUTION: When a threshold of an IGBT 6A is lower than the other IGBTs, the output of a gate drive circuit is changed from -1.5 V to +1.5 V. Then, the potential of a gate terminal 9 is increased. When the potential of the gate terminal 9 is above the threshold of the IGBT 6A, a current I6A is carried at the IGBT 6A, and a voltage VL (=L* differential (I6A)) is generated. The voltage VL lowers a G-E voltage of the IGBT 6A with respect to a voltage between the gate terminal and the emitter terminal, so only the IGBT 6A with a lower threshold has a lower G-E voltage. Thus, a turn-off is delayed, preventing current imbalance.

Abstract: PURPOSE:To prevent an eject of a holder part from being executed before unloading is completed, by forming an engaging holding part by providing a notch on the second engaging part, and providing an elastic part for compensating a deflection generated in each part when an engagement of a slide part and a cassette eject part by the engaging holding part is continued until the time when a magnetic tape is contained. CONSTITUTION:At the time of loading of a magentic tape, a projection 15 moves in the direction C together with a loading part 9, therefore, a slide part 10 turns in the direction D by a spring 13, and the first engaging part 12 is engaged with the second engaging part 11. By this engagement, a movement in the direction B of a cassette eject part 7 is limited. Thereafter, until unloading is completed, the first engaging part 12 goes into an engaging holding part 16 and the engagement is held. In this case, a spring plate 17 is bent, and a deflection of each part is compensated. In this way, even if the cassette eject part 7 is energized in the direction B by always pushing an eject lever 8, it does not occur that a holder part 1 is ejected before unloading is completed.
