Patent EP-0269770-A1 (EP)
Inventor: KAGAWA HIROHIKO
IPC: C08K3/00
Filed: 1986-12-04
Abstract: An epoxy resin encapsulating composition for semiconductor packages consisting essentially of an epoxy resin adduct of epichlorohydrin and an aromatic hydroxyl-containing compound, and an inorganic ion-exchange solid material admixed with the epoxy resin adduct. The ion-exchange solid material is selected to have the capability of exchanging its mobile anions with the undesired chlorine ions which occur inherently in the package made from the encapsulating composition and are very likely to corrode the metallic conductor on the semiconductor to be encapsulated. The ion-exchange solid material is characterized to include antimony and bismuth as basic materials forming an ion-exchange network which carries the mobile anions to be substituted with the chlorine ions. This ion-exchange material also is found to be also effective for trapping undesired alkali metal ions, for example, Na⁺ which may be present in the composition itself or permeate in the packages made therefrom and also act to corrode the conductor. Preferred ion-exchange material for the epoxy resin encapsulating composition is found to be represented by the formula: 
    SbBixOy(OH)z(NO₃)w·n(H₂O) 
in which x represents 0.2 to 2.0, y represent 1.0 to 5.0, z represents 0.1 to 3.0, w represents 0.1 to 3.0 and n represents 0.5 to 3.0.

Abstract: A microwave frequency multiplier employs a first self-biasing unidirectional conductive means (112) such as self-biasing diode means and a second self-biasing unidirectional conductive means (114) such as self-biasing diode means coupled in anti-parallel relationship across a signal input, each of the self-biasing diode means including a diode and a biasing elements. The first self-biasing diode means and second self-biasing diode means cause a bias to occur at internal nodes which increase with increased input power for a broad range of input power levels. The presence of internal biasing results in waveform clipping at higher signal levels. Relative to prior art, the conversion loss will remain optimum up to high input power over an entire high-power input range. The self-biasing diode means in one embodiment comprises a diode coupled in series with a parallel combination of a resistive element (R1) and a capacitive element (C1), the resistive element for developing a voltage drop across the capacitive element suitable to bias the diode, and the capacitive element being of sufficient capacitance to maintain a voltage bias level across the resistive element. The time constant determined by the values of the resistive and capacitive elements should be on the same order of magnitude as the period of the input signal. Addi­tional external bias may be employed in alternative embodiments. In addition, further diodes (D3, D4) may be added to the self-biasing diode means to provide further breakdown protection.

Preferably the assay medium incorporates a masking or quenching agent which suppresses signal generated in regions of the assay medium remote from the signal sensing means.

Abstract: L'appareil et le procédé ci-décrits permettent d'obtenir la compacité des sytèmes réfringents de la technique antérieure tout en évitant le recours à des éléments réfringents qui posent des problèmes de dispersion du faisceau, d'adsorption et de sensibilité aux températures. Un réflecteur d'orientation (74) est positionné dans la trajectoire du faisceau entre un réflecteur d'étalement (72) et un réflecteur de collimation (76). Le faisceau d'entrée de faible diamètre est dirigé sur le réflecteur d'étalement (72), lequel provoque sa divergence, est renvoyé par le réflecteur d'orientation (74), et atteint le réflecteur de collimation (76). Ce dernier élément collimate le faisceau et le réfléchit vers le réflecteur d'orientation (74) qui oriente le faisceau le long d'un axe de sortie (78) désiré. Les réflecteurs d'étalement, d'orientation et de collimation sont positionnés les uns par rapport aux autres de telle manière que l'axe du faiscau soit modifié lors de chaque réflexion à partir de chaque élément. Le réflecteur d'orientation (74) peut être mis en oeuvre sous la forme d'un miroir plan, ou bien en variante peut comporter une surface réfléchissante convexe qui coopère avec le miroir de collimation (76) afin de collimater pleinement le faisceau étalé.
