There is provided an antenna whose outside shape can be miniaturized while maintaining a gain at a desired level with respect to a radio wave of a wide frequency range. The antenna is configured by using a core of a laminate structure. The core is a plate of a rectangular outside shape, configured to have a laminate structure including each of first, second and third resin layers. The first resin layer has magnetic powder mixed therein and formed as a middle layer, and the second resin layer and the third resin layer made of resin only without magnetic powder mixed therein are formed to sandwich the first resin layer therebetween. In the core of the laminate structure, it is preferable to use a polymer resin for each of the resin layers, and to use soft ferrite powder as the magnetic powder.

A heat pump type air conditioning system comprises an air duct in which air flows in a given direction with an aid of an electric air blower. A condenser is disposed in the air duct. A compressor has an outlet connected to an inlet of the condenser. A receiver dryer has an inlet connected to an outlet of the condenser. An outside expansion valve has an inlet connected to an outlet of the receiver dryer through a first passage. An outside evaporator has both an inlet connected to an outlet of the outside expansion valve and an outlet connected to an inlet of the compressor through a second passage. An inside evaporator is disposed in the air duct at a position upstream of the condenser. An inside expansion valve has both an inlet connected to the first passage and an outlet connected to an inlet of the inside evaporator. A coolant distributing circuit is further employed which feeds the inside evaporator with at least a part of coolant discharged from the receiver dryer when the coolant pressure in the inside evaporator exceeds a predetermined degree.

A sublime type thermal transfer printer uses an ink sheet on which a fixing agent of a sublimation ink is coated and thermally transfers the fixing agent of the ink sheet onto a plain printing paper first, then thermally transfers an image on the ink sheet onto the area of the printing paper where the fixing agent is transferred by subliming an ink coated on the ink sheet.
摘要:
An apparatus for measuring the density or the like of an object from the level of transmission through the object of gamma rays having different energy levels which are transmitted at the object by a gamma source having a predetermined solid angle of transmission. A collimator collimates gamma transmitted through the object and a scintillator generates light corresponding to the output of the collimator. Plural photomultipliers generate position-dependent electrical signals corresponding to the light generated by an incident gamma ray photon to the scintillator. A calculating circuit generates a density spectrum for the object from the position-dependent electrical signals by integrating the position-dependent electrical signals corresponding to each of the incident gamma ray photons to the scintillator.
摘要:
A reinforcement member for an automobile door is constructed of a central piece formed from a plate of a high tensile strength steel and two end pieces of a mild steel that is the same material as the material forming an inner panel of the automobile door. The two end pieces are secured to end portions of the central piece and formed with attachment areas, respectively, at which the reinforcement member is secured to the door inner panel.

A printing apparatus employs a nearly linear conveying path P2 for printing paper P from a position confronting the platen roller 6 and thermal head 7 for composing the printing unit 3 to the paper discharge unit 2. The capstan roller 4, pinch roller 5, and discharge rollers 10, 10 are disposed opposedly to the conveying path P2, and at an intermediate position of the conveying path P2 intersects the conveying path P1 from the paper supply unit 1 to the printing unit 3. A paper supply port is disposed at the bottom of the paper cassette forming the paper supply unit 1, so that the conveying path P1 from the paper supply port to the printing unit 3 is shortened, and accordingly the paper conveying path is shortened. The printer construction simplified and downsized, while the precision of positioning of the printing paper and positioning of the printing head is enhanced, so that the printing quality may be improved.
摘要:
A method and portable apparatus for measuring radiation dose and identifying a source radionuclide. Energy correction to calibrate detected charge to .gamma.-ray energy level is made through the use of naturally occurring radiation from 40K in a potassium compound KCl. One embodiment includes a portable scintillator and photomultiplier (PMT) along with an accumulation memory, an input means, a signal processing circuit, a memory and an output means. A warning function informs of an abnormality when the difference between the measured radiation data and the standard data in the device memory exceeds a predetermined value.
