A disc clamping device seeks to attain size reduction and simplification of the structure without spoiling the smoothness of centering a disc. A disc clamper has an upwardly projecting central hung pin penetrating a circular hole formed in a clamp support member and having a head greater in diameter than the circular hole. At least either one of the portions of the edge of the circular hole and the head of the hung pin in engagement with each other is formed with a tapered surface for centering the disc clamper. The clamp support member is provided with an elastic member, for instance a leaf spring, for pushing the head against the edge of the circular hole.

Provision of a recording medium transfer apparatus, which uses a one-direction motor as a drive source and is simple in construction and inexpensive. The apparatus comprises a rotation member driven for rotation by the one-direction motor, an idler gear, and transfer means. The rotation member has a partial gear and a push member. The partial gear is held in mesh with the idler gear only during rotation of the rotation member for a predetermined angle. The transfer means has a gear portion in mesh with the idler gear and a contact portion. The transfer means is caused, with the contact portion thereof pushed by the push member, to undergo rocking movement in one direction and, after separation of the push member from the contact portion, the transfer means is rocked in the other direction with the partial gear in mesh with the idler gear. The recording medium is thus reciprocally transferred by the transfer means with reciprocal rocking movement thereof caused during one rotation of the rotation member.

It is an object of the present invention to provide an energy-saving image forming apparatus capable of fixing toner in a reliable manner to enhance the quality of images, control the temperature of toner residue to reuse the toner in a reliable manner, and reduce the power consumption of the apparatus. In a copier, a photoconductive drum carries a toner image to be transferred to a recording medium, a heater of a fixing unit fixes the transferred toner image on the recording medium, and a cleaning unit removes toner residue on the photoconductive drum after transfer. The whole copier is covered with a housing, a first ventilation system ventilates the inside and outside of the housing, and a controlling section regulates the amount of ventilation by the first ventilation system in accordance with an output from a temperature sensor for detecting the temperature of the cleaning unit. As a result, it is possible to effectively reuse the collected toner and ensure excellent quality images.

An ultrasonic motor has a piezoelectric element driven by application of a voltage thereto to undergo expansion and contraction. A vibrating body is vibrationally driven by the expansion and contraction movement of the piezoelectric element to thereby produce standing waves. A moving body is frictionally driven by the standing waves of the vibrating body. Power transmission projections apply a frictional force to the moving body to thereby frictionally drive the moving body in accordance with the standing waves. The power transmission projections are disposed only every preselected number of wavelengths at intermediate positions between loops and nodes of the standing waves, the preselected number being a natural number.

A post-processing apparatus of a digital image forming apparatus includes first and second bins for storing recorded matter which was output from the digital image forming apparatus and distributed to the respective bins based on image information data such as the name of data contained in the image information relating to the recorded matter. Each of the first and second bins has a display device for displaying the image information data corresponding to recorded matter to be stored in the respective bins, such as the sender of facsimile, the name of data and the name of client who output the data. By displaying on the bins the image information data belonging to the recorded matter, such as the sender of facsimile, the name of data and the name of client who output the data, the operator can easily find the target recorded matter.

The present invention is directed to provide an improved structure of a sash of the side door for automobiles, wherein rigidity of the door sash, hence rigidity of the side door as a whole, is augmented without increase in weight of the door sash, and without causing hindrance to the surrounding view. Such structure is realized by the box-shaped transverse sectional part (45) provided over the entire length of the door sash (4, 4A, 4B, 4C), of which the size (w) in the breadthwise direction of the vehicle is gradually changed, thereby progressively reducing thickness (W) of the door sash (4, 4A, 4B, 4C) in the breadthwise direction of the vehicle.

A method for bonding two objects by means of the following two adhesives:(A) a moisture-inducible room temperature anion polymerization curing adhesive composed essentially of at least one anion polymerizable compound selected from the group consisting of an .alpha.-cyanoacrylate compound of the formula: ##STR1## wherein R is an alkyl group having from 1 to 16 carbon atoms, an alkoxyalkyl group having 2 to 16 carbon atoms, a haloalkyl group having from 1 to 16 carbon atoms, a cyanoalkyl group having from 2 to 16 carbon atoms, an aralkyl group having from 6 to 12 atoms, an acyloxyalkyl group having from 2 to 16 carbon atoms, a cycloalkyl group having from 3 to 16 carbon atoms, an alkenyl group having from 2 to 16 carbon atoms or an aryl group having from 6 to 12 carbon atoms, and a 1,1-disubstituted diene compound of the formula: ##STR2## wherein each of R.sup.1 and R.sup.2 which may be the same or different, is a hydrogen atom, an alkyl group having from 1 to 5 carbon atoms, an aryl group, an aralkyl group having from 6 to 12 carbon atoms or a halogen atom, R.sup.3 is a hydrogen atom or a methyl group, each of X and Y which may be the same or different, is a cyano group, a carboxylic acid ester group having from 2 to 12 carbon atoms, an ethylsulfone group, a phenylsulfone group, a formyl group, an acetyl group, a benzoyl group, an amide group, a diethyl sulfonyl group, or a phenyl group; and(B) a room temperature self-curing adhesive containing from 0.05 to 50% by weight of an anion polymerization accelerator, said self-curing adhesive being selected from the group consisting of (1) a room temperature moisture-curing adhesive, (2) a room temperature curing two-part type epoxy resin adhesive, and (3) a room temperature curing synthetic resin aqueous emulsion adhesive, which comprises applying said two adhesives (A) and (B) at the bonding interface of the objects so that they do not contact each other and pressing the objects to each other to bring the two adhesives in contact with each other.
摘要:
A vacuum type circuit breaker which has an operating lever (31) connected at one end thereof to the movable electrode (102) of a vacuum switch tube (1) and at the other end to a closing spring (55) through an energy storage link mechanism (54). The operating lever (31) functions to drive the movable electrode (102). The energy storage link mechanism (54) is provided with an energy storage crank (52) pivotally supported on a shaft (2051). The force which the energy storage link mechanism (54) applies to the operating lever (31) is set such that it is less than a force on the operating lever (31) which is produced by the difference between the internal pressure of the vacuum switch tube (1) and atmospheric pressure. This arrangement makes it possible, upon occurrence of vacuum loss, to detect the vacuum shortage, whereupon the closing of the switch is prevented to thereby avoid an accident due to vacuum degradation.
