摘要:
A digital signal processor of a simple circuit configuration capable of implementing arithmetic processes and interruption processes efficiently in a reduced number of steps at a high processing speed. The digital signal processor comprises instruction execution pipeline stages including a stage in which data is read from a data memory and the data is applied to an arithmetic unit; an arithmetic unit for the execution stage, including a barrel shifter, a multiplier and an arithmetic and logic unit, a normalizing barrel shifter, a round-off/accumulation adder, internal data memories and a DMA transfer bus for a write/accumulation stage, an address generating unit capable of parallel and two-dimensional generation of two inputs one output data memory addresses and a DMA control unit for controlling the two-dimensional data transfer through a DMA bus between the internal data memories and an external data memory for an instruction execution stage.

A door hinge of the type comprising a first metal plate having one vertical side edge formed integral with a pin and a second metal piece having one vertical side edge formed integral with a second knuckle cylinder into which is fitted the pin. A load plug is slideably fitted into the second knuckle cylinder for engagement with the upper end of the pin and the second knuckle cylinder is formed with an engaging portion for preventing the load plug from being displaced from a predetermined position. A compression spring means is loaded in the second knuckle cylinder above the load plug so as to press the load plug against the engaging portion, whereby a load applied axially to the pin is carried by the compression spring means through the load plug. When the upper or lower side edge of the door interferes with a gate frame due to an earthquake or the like, the first and second plate metals are caused to move toward or away from each other so that the interference between the door and the gate frame is eliminated and the door is moved upwardly or downwardly relative to the gate frame. Therefore even when the gate frame is distorted, the door can be positively opened.

A card operated lock includes a lock box in which an inner card slit opened to the interior of a room and a outer card slit opened to the exterior of the room are disposed in substantially coplanar relationship with each other. A lock card having a predetermined pattern of punched engaging holes is inserted previously into the inner card slit while a key card comprising the same pattern of punched engaging holes as the lock card is inserted into the outer card slit when the lock is unlocked or opened. A plurality of rocking tumblers each of which is substantially in the form of a T-shaped plate are inserted into the lock box in the form of an array extended in the widthwise direction of the key card and perpendicular to the card slits. A horizontal bar portion of each T-shaped rocking tumbler is extended along both the inner and outer card slits. Each T-shaped rocking tumbler is biased in a direction in which a pair of detection projections extended from the horiozntal bar portion of the T-shaped rocking tumbler in symmetric relationship with each other with respect to a vertical bar portion of the T-shaped rocking tumbler are pressed against the lock and key cards inserted in the inner and outer card slits. Each T-shaped tumbler is guided so that it can be displaced over a distance at least equal to the thickness of the card in the direction of thickness thereof and it can be rocked or swung, whereby the punched engaging hole patterns of the lock and key cards are determined to be coincident with each other depending upon whether or not all rocking tumblers are maintained upright.

摘要:
A linked scan type mass spectrometer wherein the mass number of a metastable ion originating from a precursor ion is measured by scanning the magnetic and electric fields at a constant ratio between the two fields. Calculation is performed on a first electrical signal representative of the mass number of the precursor ion, a second electrical signal corresponding to a value of the electric field at which the mass number of the precursor ion is detected, and a third electrical signal corresponding to a value of the electric field at which the metastable ion is detected during scanning of the electric field and magnetic field, to thereby determine the mass number of the metastable ion. The third electrical signal is obtained by measuring a value of the magnetic field which contributes to the dispersion of ions. Means is provided for correcting the measured value of the magnetic field, thereby determining the mass number of the metastable ion with high accuracy.
