摘要:
A circuit board includes a printed circuit board layer, an insulating layer, and an electromagnetic interference sealed layer. The printed circuit board layer includes an insulating substrate on which circuit patterns are printed. The insulating layer covers the circuit patterns. The sealed layer covers the insulating layer and connected with a ground portion of the circuit patterns. The sealed layer that is formed by screen printing conductive paste has through holes. Edges are formed around the through holes other than the outer edges, and a total area of edges at which the thickness of the printed conductive paste is large due to surface tension increases. Thus, the sealed layer can be easily formed in a predetermined thickness, and stability in conductivity of the sealed layer can be maintained.

An instrument panel unit of a vehicle incorporates a radio signal receiver formed on a circuit board which is fixed over a meter circuit board in parallel thereto within a meter housing. It is disposed so that an antenna inlet on the circuit board is located in one outer region among longitudinally trisected regions of the meter circuit board. The meter circuit board works efficiently as additional part of antenna, thereby improving the signal receiving performance inclusive of the antenna gain of the receiver.

A method for continuously steaming rice includes the steps of evenly placing rice on a moving carrying surface of a single conveyor belt after the rice absorbed water, primarily steaming the rice by blowing steam to the rice placed on the carrying surface, sprinkling of hot water to be absorbed into the rice, and secondarily steaming the rice by blowing steam into the rice. These steps are performed successively without agitating the rice on the single conveyor belt within a sealed housing. The apparatus has a housing (4, 5) made up of a lower housing member (4) and an upper housing member (5) capable of moving vertically relative to the lower housing member (4). The boundary between the upper and lower housing members (5,4) is sealed by drained water during a steaming step.

A shock absorber control system comprises a plurality of switches for setting respective desired dampening forces, and controls a dampening force of a vehicle shock absorber linearly in accordance with a manipulation of one of the switches. The control system further comprises a height sensor for detecting a height of the vehicle and detects the dampening force of the shock absorber by the change of the detected height and corrects the dampening force of the shock absorber in accordance with a difference between the desired dampening force corresponding to the manipulated switch and the detected dampening force.

A receiver includes a circuit board and a dielectric antenna. The circuit board has a receiving circuit on a first surface, and a ground pattern on a second surface. The circuit board is disposed close to a rear window of a vehicle so that the ground pattern faces a roof panel. The dielectric antenna extends from an edge of the circuit board toward and along the rear window. As a result, the roof panel capacitively couples with the ground pattern, so that the roof panel becomes imaginary ground. The dielectric antenna functions as a monopole antenna with the imaginary ground. It is not influenced with a metallic material of the vehicle.

A circuit board includes: a substrate; a conductive pattern disposed on a surface of the substrate; a lower insulation layer disposed on the conductive pattern to cover the conductive pattern except for an opening, through which the conductive pattern is partially exposed from the lower insulation layer; a conductor disposed on the lower insulation layer and connecting to the conductive pattern through the opening; an upper insulation layer disposed on the conductor for covering the conductor and the lower insulation layer; and a test coupon disposed on the substrate for evaluating the conductor.

To provide an apparatus for producing frozen cooked-rice in an appropriately individuated state without needing complicated and special apparatus constructions, and without breaking down the individual grains of rice, cooked rice is primary-frozen as an entire block by cold air blown from air blast supply devices into the state where the individual grains of rice are not frozen up to their cores. The cooked-rice thus partly primary-frozen is brought by compressed cold air blown by a compressed-cold-air intermittent supply tube and/or by a rotary disjointing device comprising a rotary comb and a stationary comb into the form of appropriate-size blocks or small lumps which are then secondary-frozen by cold air blown from air blast supply devices into a state where the individual grains of rice are frozen completely up to their cores.
摘要:
A printed board has a board, an electrically insulative membrane, formed on the board, and an electrically conductive membrane, formed on the electrically insulative membrane, in its area where a control circuit, including a CPU and etc., is installed. The electrically conductive membrane is electrically connected with ground patterns of a wiring pattern. Accordingly, ground connections at the control circuit are sufficiently performed. Therefore, even though ground connections in an area other than the control circuit are not sufficiently performed, a magnetic noise is prevented from being generated in a loop-shaped electricity supply line passing through a CPU and etc. Consequently, noises in printed board can be effectively reduced.
