摘要:
A band-pass filter which includes a plurality of dielectric coaxial resonators which are arranged in a parallel relation and extending axially in the same direction, and have respective coupling terminals inserted therein, and a dielectric substrate formed, on its first surface, with a plurality of coupling electrodes for connecting the respective coupling terminals. The coupling electrodes on the first surface of the dielectric substrate have an inductance element between them for connecting at least two coupling electrodes to each other. Confronting electrodes facing the coupling electrodes are formed on the other surface of the dielectric substrate to from a capacitance bypass circuit. The inductance element may be a printed circuit on the dielectric substrate or an air-core coil. The air-core coil may be located either adjacent the first surface of the substrate, or away from the substrate between the resonators.

A dielectric filter includes a conductive cover formed by bending a metal plate and forming at least one inwardly projecting portion at a predetermined position along the bent portion. The inner surface of the at least one inwardly projecting portion abuts on an open circuit surface or edge of a dielectric block. Thus, the distance between the open circuit surface of the filter and the conductive cover is reliably maintained and unnecessary coupling between adjacent resonators is prevented.

In an instruction processing unit, a first register group having at least one register whose bit width is enough for designating a desired address in the entire address space of a memory, and a second register group having at least one register whose bit width is not enough for said purpose, and operation means are provided. This operation means further includes first and second address generation means. In this unit, the first address generation means creates a desired operand address according to values stored in one or more registers in the first register group. The second address generation means creates an operand address to designate a desired partial space of the memory, by extending the bit width of a register in the second register group by a required amount.

A cooling apparatus has a cooling vessel, containing a liquid as a thermal medium which absorbs latent heat by evaporation, and an absorber which absorbs the vapor of the liquid. The cooling vessel further contains one or more units of encapsulated gel refrigerant submerged in the liquid, which impede temperature increase of the liquid when an operation of the cooling apparatus is temporarily suspended. An alternative cooling vessel has one or more upwardly extending members partially submerged in the liquid and covered with liquid soaking material, so that the liquid soaks up in the material by capillary action and accelerates its evaporation. Another alternative cooling vessel has plural liquid tanks, one arranged on another, so that the total area for the evaporation of the liquid is multiplied. An additional alternative cooling vessel has a plurality of rotatable fins, partially submerged in the liquid, for accelerating the evaporation of the liquid.

An adsorption cooling apparatus includes a hermetically sealed cylindrical capsule that contains a first thermal medium, a moisture absorber on its first side and an adsorbent on its second side. The capsule reciprocatively moves and slidably contacts with a cooling vessel containing a low temperature thermal medium on the first side and with a heating vessel containing a high temperature thermal medium on the second side. The capsule is cooled by an external airflow when it is moved to the cooling vessel, so that the first thermal medium absorbed in the moisture absorber evaporates and the low temperature thermal medium in the cooling vessel is cooled because of the latent heat of evaporation of the first thermal medium. The so cooled low temperature thermal medium is utilized for cooling the object to be cooled. The first thermal medium having evaporated from the moisture absorber is adsorbed by the adsorbent. When the capsule has moved to the heating vessel, the adsorbent is heated by the heating vessel, and the first thermal medium having been adsorbed in the adsorbent is desorbed and released from the adsorbent. The first thermal medium so released is again absorbed by the moisture absorber when the capsule has moved back to the cooling vessel, and the capsule is cooled again by the airflow to repeat the cycle.
