A compact ultrasonic motor is made easy to assemble and replace in an electronic apparatus by providing various electronic circuit components on a connector formed integrally with the ultrasonic motor. In one embodiment, a piezoelectric element is in contact with a vibrating body for undergoing vibration along with expansion-and-contraction movement of the piezoelectric element. A moving member is in contact with the vibrating body for undergoing movement in a desired direction in response to vibration of the vibrating body. A support member supports the piezoelectric element, the vibrating body, the moving member, along with a driving circuit for driving the ultrasonic motor and a connector for connecting the piezoelectric element to the driving circuit. The driving circuit is an AC signal generating circuit for supplying an AC signal to the piezoelectric element and a phase adjusting device for adjusting phase characteristics of the AC signal generating circuit. By providing the driving circuit and the connector on the support member, the ultrasonic motor is compact and easy to handle.

A hot melt ink which is applicable to an ink jet printing system where the hot melt ink is jetted out to a printing medium to form an image on the printing medium includes a binder which contains a hot melt composition; a coloring material which is dispersed in the binder; and a photo-curing composition. The binder as a dispersion medium is dispersed in the photo-curing composition in the form of grains and a surface of the hot melt ink is covered with the photo-curing composition when the hot melt ink is fixed on the printing medium. An ink jet printing apparatus includes a jetting device which jets the above hot melt ink melted by heat out to a printing medium to draw an image on the printing medium; and a light source for irradiating the hot melt ink on the printing medium which is jetted out from the jetting device to cure the photo-curing composition.

A small, efficient and stable ultrasonic motor is provided, wherein force is prevented from varying before and after assembly and can be adjusted after assembly without requiring troublesome operations. An electronic apparatus with such a ultrasonic motor is also provided. The ultrasonic motor has a force applying device for applying a force to a vibrating member to be vibrated and to a moving member placed in abutment against the vibrating member to cause a frictional force therebetween so that the moving member is driven by the frictional force. The force applying device comprises a main force applying device for applying a main force and a force adjusting elements for adjusting the force applied by the main force applying device. In one embodiment, the main force applying device is a leaf spring and the force applying elements are slits formed in the leaf spring and strips formed between the slits. Adjustment of the force applied by the leaf spring is performed by removing one or more of the strips.

A grinding body for on-line roll grinding has a grindstone of a cup shape. The grindstone is on a surface portion, and near a peripheral edge, of a circular support base plate, so that a peripheral edge portion of the circular support base plate has on a surface side thereof a two-layer structure. This two-layered structure includes a flat ring-shaped portion jutting toward an inner periphery so as to define a groove opening inward. The grindstone is mounted on the flat ring-shaped portion; and a damping material is filled and mounted into the groove. This grinding body can effectively prevent the formation of a spiral mark and a pitching surface mark, improve the grinding power and grinding accuracy, and prolong the life of the grindstone.

Disclosed is an internal combustion engine having a combustion heater wherein, in the case of attaching a supercharger to a intake path of the internal combustion engine, the combustion heater provided on a intake path can be surely ignited, and the intake air can be prevented from flowing back within the intake path even when the supercharger operates. The vaporizing type combustion heater is connected in bypass via an air supply path, a combustion chamber body and a burned gas discharging path as components thereof to a intake pipe of the internal combustion engine, through which the intake air flows towards cylinders of the engine. A compressor of a turbo charger is not provided between a connecting point to the air supply path and a connecting point to the burned gas discharging path along the intake pipe.

An ink cartridge takes the form of a bag, and is formed out of a laminate which includes films laminated together. Compressive stress exists in one of the films. Therefore, when a hollow needle pierces the bag, the stress causes this film to function in such a manner as to block the pierced hole. This brings the film into close contact with the needle, preventing ink leakage securely. It is also possible to prevent the cracks developed in the laminate by external injuries from progressing. It is possible to form the laminate by bonding a plurality of films having different coefficients of thermal expansion together at high temperature, and cooling the bonded films. It is possible to form the bag by heat-sealing the laminate.

In a toner-fixing heater device, a heater strip in a meandering pattern and a pair of heater electrodes are formed on an insulator film which is in turn fixed to a cylindrical roller body. Each heater electrode which slidably contacts a brush electrode has a leading and trailing edges formed inclinedly at an inclination angle .theta., e.g., 50.degree.. The axial width Wd of the heater electrode 14, the circumferential width Wg of a spacing between the leading and the trailing edges, and the circumferential width Wb of the brush electrode are determined to satisfy (Wd/tan .theta.+Wd).gtoreq.Wg. This arrangement assures a continuous sliding contact between the heater electrode and the brush electrode.

摘要:
In an asynchronous transfer mode (ATM) cell transfer apparatus, a valid cell detecting circuit determines whether or not each of ATM cells is valid, based on a specific data of the ATM cell. When it is determined that the ATM cell is not valid, the valid cell detecting circuit discards the ATM cell. On the other hand, when it is determined that the ATM cell is valid, the valid cell detecting circuit writes the ATM cell in a buffer circuit. A read control circuit reads out the ATM cell from the buffer circuit.
