A reservoir tank includes a main portion and a storage chamber disposed in the main portion for storing operating fluid, with the storage chamber being surrounded by a side wall, a ceiling portion and a bottom portion. A float is disposed in the storage chamber and is adapted to move vertically corresponding to the height of the operating fluid level, and a reed switch is operatively associated with the float so as to operate in accordance with the height of the float. A partition member divides the storage chamber into an upper space and a lower space in which the operating fluid and the float are disposed.

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.
摘要:
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 brake pressure control system for a wheeled vehicle includes a swingable lever pivotally mounted at a first end portion thereof to a sprung mass of the vehicle such as a body frame, a first tension coil spring connected at a first end thereof to the sprung mass and at a second end thereof to a second end portion of the swingable lever to bias the lever toward the sprung mass, a second tension coil spring connected at a first end thereof to an unsprung mass of the vehicle such as a wheel axle and at a second end thereof to the second end portion of the swingable lever to bias the lever against the biasing force of the first spring, a bushing rotatably mounted on the second end portion of the swingable lever, the bushing being formed with a first support portion for retaining the second end of the first spring and a second support portion for retaining the second end of the second spring, and a modulator valve secured to the sprung mass and incorporated in a hydraulic connection between a master cylinder and a wheel brake cylinder, the modulator valve having a spring-loaded valve member which is carried on the swingable lever to be applied with a biasing force proportional to the vehicle load.
摘要:
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.
