摘要:
The present invention relates to a broadcast service system where a broadcast transmission terminal is connected to a broadcast reception terminal through a plurality (large number) of switching nodes. The object of the invention is to provide a broadcast service system which has a small number of connection paths between switching nodes and can receive selectively, freely and arbitrarily broadcast program from the broadcast reception terminal. In the broadcast service system where a broadcast transmission terminal is connected to a broadcast reception terminal via a network having plural or many switching nodes, distribution modules, which control distributively input information, are formed so as to arrange to each or some of the switching nodes as an external circuit to an exchange switch in corresponding switching nodes.

A decorative member composing a casing includes: a resin layer (2) having a front surface (2b) and a back surface (2a); and a reflective layer (3) formed on the back surface (2a) of the resin layer (2). The back surface (2a) of the resin layer (2) includes a receding surface (21) formed therein. The receding surface recedes gradually toward the front surface (2b) to change a thickness of the resin layer (2). The receding surface (21) is a concave surface forming a depression that opens while broadening. The back surface (2a) of the resin layer (2) has a reference surface (22) around the receding surface (21), and a portion of the reference surface (22) facing an internal space of the casing is a roughened area (4).

A toner replenishing device for an image forming machine has a hopper housing with a toner agitating passageway and a toner carrying passageway, a toner agitator disposed in the toner agitating passageway for agitating recovered toner and fresh toner supplied to the toner agitating passageway and lifting them to the toner carrying passageway, and a toner carrier disposed in the toner carrying passageway for carrying the recovered toner and the fresh toner agitated and lifted by the toner agitator. The toner agitator has a first paddle disposed in a first end part of the toner agitating passageway, and a second paddle disposed on the other end part side of the toner agitating passageway and adjacent to the first paddle. The first paddle has the function of sending the toner to the other end part side of the toner agitating passageway, while the second paddle has the function of sending the toner to the first end part side of the toner agitating passageway.

In an electromagnetic valve device, in order to secure a core assembly to a housing, an annular spacer is used. The annular spacer is fitted between a conical inner surface of a receiving portion of the housing and a conical opening of a casing. Since the conical opening of the casing is mounted on a tapered surface of a stationary core accommodated in the receiving portion of the housing, the core assembly is secured to the housing.

A brake control device for vehicles includes a master cylinder, a plurality of wheel cylinders, and an anti-lock control apparatus disposed between the master cylinder and the wheel cylinders of at least one hydraulic circuit. The anti-lock control apparatus includes a hydraulic pump, a reservoir and a changeover device which is selectively changed over at least between a first condition which permits an increase in the hydraulic pressure of the wheel cylinders of at least one hydraulic circuit and a second condition which permits an decrease in the hydraulic pressure of the wheel cylinders of at least one hydraulic circuit in response to the locking condition of the road wheels. The hydraulic pump includes a housing, a slidable piston device for defining a pump chamber which is communicated with the reservoir and the changeover device at a side of one end thereof in the housing, an inlet check valve disposed between the pump chamber and the reservoir for permitting fluid communication from the reservoir to the pump chamber and for interrupting fluid communication from the pump chamber to the reservoir, an outlet check valve disposed between the pump chamber and the changeover device for permitting fluid communication from the pump chamber to the changeover device and for interrupting fluid communication from the changeover device to the pump chamber, and a piezo element for reciprocating the piston device disposed at the other end of the piston device.

A molded saddle for an electrode plate of a battery having a horizontal base plate and a flexible raised support plate portion for supporting legs of positive plates. When the molded saddle is attached to the inner bottom surface of a battery container, a large vertical space between an upper end portion of the flexible raised support plate portion and the inner surface of the bottom of the container is provided so that when the positive plate of a plate assembly is extended, the flexible, raised support portion supporting the positive plate is pushed in order to be lowered by the extension of the positive plate so as to absorb the extension resulting in the prevention of the positive plate from being warped.

A variable magnification electrostatic copying apparatus comprising a transparent plate on which to place a document to be copied, an optical system for projecting the image of the document onto an electrostatographic photosensitive member at any desired projecting ratio selected from a plurality of projecting ratios in an exposure zone located along the moving path of the photosensitive member, and a driving means for moving at least a part of the optical system and the transparent plate relative to each other. The optical system includes at least one position-variable optical element assembly adapted to be held at any of a plurality of positions corresponding to the aforesaid plurality of projecting ratios. The variable magnification electrostatic copying apparatus includes a unique improved means for varying the projecting ratio of the optical system by moving the position-variable optical element assembly.
摘要:
An electrostatic copying method of the transfer type which comprises repeatedly performing a copying cycle including an image-forming step of forming a latent electrostatic image on a photosensitive material moved through an endless moving path or a toner image obtained by developing it, a transfer step of transferring the latent electrostatic image or the toner image on the photosensitive material to a receptor member subsequent to the image-forming step, and a cleaning step of cleaning the photosensitive material subsequent to the transfer step. When the width or length of a receptor member to be used in the next copying cycle is found to be larger than the width or length of a receptor member used in the preceding copying cycle as a result of comparison of at least one of the width and length of the receptor member to be used in the next copying cycle respectively with at least one of the width and length of the receptor member used in the preceding copying cycle, the above cleaning step is additionally performed after the end of the preceding copying cycle before the next copying cycle is started.
