A brake hose comprises reinforcing layers in a rubber base. The brake hose comprising an inner tube rubber layer that is made of a rubber material and has a flow path for flowing fluid; a lower yarn layer formed by braiding lower yarn around the inner tube rubber layer; an intermediate rubber layer made of a rubber material and located around the lower yarn layer; an upper yarn layer formed by braiding upper yarn around the intermediate rubber layer; and a cover rubber layer formed around the upper yarn layer. The intermediate rubber layer is formed from a sheet material having a Mooney viscosity of 10-40 Mv (minimum Mooney value) at 145° C.

A brake hose includes two reinforcing layers in a rubber base. The brake hose comprises an inner tube rubber layer having a flow path for flowing fluid, a lower yarn layer formed by braiding first yarns around the inner tube rubber layer and an upper yarn layer formed by braiding second yarns around the lower yarn layer and a cover rubber layer covering the upper yarn layer. A lower yarn layer duty LD given by the equation, LD(%)=(LRP/PRP)×100, has a value of 50-65%, where LRP denotes an inner pressure at which a brake hose without the upper yarn layer and the cover would burst, and PRP denotes an inner pressure at which the brake hose would burst.

A recording and/or reproducing apparatus including a body having a loading portion, in which a recording medium is accommodated, and a drive portion for recording and/or reproducing the recording medium; a cover joined to the body in such a manner that the cover can be opened/closed so that the loading portion is closed; and a reflecting surface formed on the outer surface of the cover so that the face or the like of a user is always reflected.

Apparatus that carries or transfers a memory medium having a solid-state memory over the inside and outside portions of a recording and/or reproducing apparatus is adapted so that, by selective engagement with respect to a chassis or a holder of a fluctuation lever the memory medium is inserted and held. The memory medium is moved in a manner bridging between an eject position where insertion/withdrawal of the memory medium is permitted and a loading position. A first biasing member moves and biases the holder in an eject direction opposite to a memory medium insertion direction is caused to store biasing force in the eject direction. A second biasing member biases the holder in the memory medium insertion direction and is caused to be operative to carry out switching between movement in the memory medium insertion direction of the holder and movement in the eject direction.

A recording and/or reproducing apparatus of a disc-shaped recording medium includes a main body portion, a shutter mechanism, a drive mechanism, an elevation mechanism and an eject mechanism. The main body portion has an opening portion through which a disc-shaped recording medium is inserted or ejected. The shutter mechanism opens and closes the opening portion. The shutter mechanism is provided on the main body portion to be freely movable and closes the opening portion under a state that the disc-shaped recording medium is completely inserted into the main body portion. The drive mechanism rotatably drivers the disc-shaped recording medium. The elevator mechanism is moved up and down in an interlocking manner with a movement of the shutter mechanism. The elevator mechanism mounts the recording medium on the drive mechanism when the shutter mechanism is moved to a position to close the opening portion, while makes the disc-shaped recording medium apart from the drive mechanism when the shutter mechanism is moved to a position to open said opening portion. The eject mechanism ejects the recording medium from the opening portion. The eject mechanism ejects the disc-shaped recording medium made apart from the drive mechanism by the elevator mechanism from the opening portion when the shutter mechanism is moved from the position to close the opening portion to the portion to open the opening portion.
摘要:
A recording and reproducing apparatus employing a flat, plate-shaped memory as a recording medium. The apparatus includes a selection operation unit for selecting data stored in the memory located at an end of a main body portion of the apparatus, where the memory is detachably loaded. The apparatus also includes an ejection unit located at an end opposing the selection operation unit for ejecting the loaded memory, thereby to prevent mistaken operations in data selection and memory ejection.
