Title: Driving device for recording medium
Inventor: TAKAHASHI KIICHI
IPC: G11B17/26
Filed: 1994-03-10
Abstract: PURPOSE:To stably transfer the recording medium positioned at a standby part to a driving unit inside and to prevent a new recording medium from being inserted to the standby part inside which is emptied by the movement of the recording medium to the driving unit.

Title: Stepped tandem master cylinder
Inventor: KUBOTA HITOSHI
IPC: B60T11/224
Filed: 1978-06-02
Abstract: PURPOSE: To attain a proper function and facilitate the machining of parts, by connecting two pistons having large and small diameters to each other so that the pistons can move relatively to each other and by interposing a spring between the pistons.  
     CONSTITUTION: A stepped blind hole is opened in the end of the piston 4, which faces another piston 5. The end 5a of the piston 5 can be inserted into the large- diameter part 4a of the blind hole. A retainer 14 is secured in the end 5a of the piston by screwing the retainer. The spring 18 is provided around the shank 14b of the retainer. The spring 18 is compressed under a preload between seats 15, 16. Only when the output liquid pressure difference between brake systems is not negligible as to practical use, namely, one brake system is defective, the spring is compressed further to move the piston 4 relatively to the piston 5. When the liquid pressure difference is negligible, it can be compensated in the cylinder. Therefore, passages and parts as needed in conventional cylinders can be dispensed with.
