Abstract:
A pressure sensor is provided with the cap (17) on a measuring portion of a diaphragm (11) to which a first end (15A) of a flexible board (15) is connected while a second end (15B) of the flexible board (15) is connected to a circuit board spaced apart from the diaphragm (11). The flexible board (15) is provided with the first end (15A), a belt portion (15C) that is bent at an angle of ninety degrees or more relative to the first end (15A) in a direction to be away from the circuit board and is curved along the outer circumference of the diaphragm (11), and the second end (15$) that is bent at an angle of nicety degrees or more relative to the belt portion (15C) to be connected to the circuit board.
Abstract:
There is provided a light emitting device and the like that achieve efficient heat radiation while production cost is reduced. The backlight device includes a backlight frame, and LED substrates that each have plural LEDs and that are mounted on the backlight frame with mounting screws. In each LED substrate, heat transmission based circuits 300 are formed. The heat transmission based circuit 300 extends from heat transmission lands 310 where the respective LEDs are mounted, via through holes 340 and heat transmission circuits 320, to a contact heat transmission land 330 where the LED substrate is fixed to the backlight frame with the mounting screw.
Abstract:
Flächige Beleuchtungseinrichtung mit auf einem Träger, enthaltend eine elektrisch isolierende Schicht (14) und eine elektrisch leitende Schicht (15), angeordneten Licht emittierenden Beleuchtungselementen (5), sog. LEDs. Die Licht emittierenden Beleuchtungselemente sind zu deren Stromversorgung mit Stromzuleitungen in Form einer Leiterbahn (3) verbunden. Die Leiterbahn ist beispielsweise eine auf die elektrisch isolierende Schicht aufgedruckte Leiterbahn. Die Licht emittierenden Beleuchtungselemente sind als Abfolge gleicher Einheiten auf einer fortlaufenden Trägerbahn, jeweils auf der elektrisch isolierenden Schicht des Trägers, angeordnet. Von den Licht emittierenden Beleuchtungselementen wird durch einen den Strom abführenden Leiter und mittels einer Verbindung zur elektrisch leitenden Schicht (15) des Trägers die Stromableitung dargestellt. Die flächige Beleuchtungseinrichtung besteht aus einer beliebigen Anzahl sich in Längs- und Querrichtung erstreckenden Einheiten. Zwischen den Einheiten befinden sich Schneidezonen, entlang derer beliebig Einheiten oder Gruppen von Einheiten abgetrennt oder herausgetrennt werden können.

Abstract:
A groove and a recess are formed on one surface of a base material, the recess being communicated with the groove and having a width and a length longer than a width of the groove. After that, liquid droplets are landed on the recess to charge a liquid into the groove communicated with the recess. Further, the liquid charged into the groove is solidified. Accordingly, the liquid can be charged into the groove having the narrow width, by merely landing the liquid droplets on the recess having a large areal size. Therefore, a fine pattern can be easily formed on the base material.
Abstract:
A reflectarray (10) utilizes switching devices (22) with non-ideal impedance characteristics to vary the impedance of reflecting elements (12). The antennas of the reflecting elements are configured as a function of the impedance of the non-ideal switching devices to provide optimal phase-amplitude performance. In particular, the antennas are configured such that the impedance of each antenna is proportional to the square root of the impedances of the non-ideal switching devices when in an on state and when in an off state.
Abstract:
An electronic device (1; 23; 26) has a contact pin (9) inserted inside a hole (5) on a printed circuit board (PCB1; PCB2; PCB3); the contact pin (9) is connected to the inner face (6) of the hole (6) to form a solely mechanical connection, the inner face (6) having no plating, and electrical contact being achieved by soldering the contact pin (9) to a pad (8; 24; 27).
