摘要:
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.
摘要:
A semiconductor photonic integrated circuit and a manufacturing method thereof involving a selective-area growth technique using a set of insulating film patterning masks formed on a semiconductor substrate. The mask width and the mask-to-mask open space width are variable but numerically limited. A single crystal growth process is carried out to form on the same substrate a plurality of contiguous bulk semiconductor layers or quantum well layers differing from one another in terms of growth layer thickness or composition. The differences in energy level between these layers are utilized so that semiconductor photonic integrated devices of different functions are formed on the substrate.

A multiprocessor system includes an address bus 170, a data bus 180, processors 110 and 120, access queues 135 and 145, shared memories 130 and 140, and lock control circuits 500 and 510. Particularly, a lock-in indicative flag register 501 is provided in the lock control circuit 500. While an operand cache 112 in one processor 110 is making a lock access to a predetermined address of the shared memory 130, the flag register 501 is set on the basis of a lock command signal 260 so that an access of an instruction cache 122 in another processor 120 to the predetermined address of the shared memory 130 is prohibited but an access to a different address is permitted at the time of the lock access. After the lock access is released, the lock control circuit 500 accepts an access to the predetermined address.

摘要:
When a mobile data communication device is rocked due to an input/output operation, a rotary shaft of a generator coupled with a weight is rotated, and power is generated. The generated power is stored in a capacitor. The power stored in the capacitor is controlled to constant voltage by a voltage stabilizing circuit and is supplied to a control circuit. In the control circuit, based on information inputted in a pointing device by supplied power, data are transmitted and received with an external data processing device through an infrared data transmitting/receiving device. Alternatively, power may be supplied from the outside of the mobile data communication device by electromagnetic induction. According to the above-mentioned configuration, not using a battery or a wire system, the mobile data communication device is capable of easily supplying power.
