Inventor: NOGUCHI MASAHIRO
IPC: H01L21/318
Filed: 1990-06-21
Abstract: Semiconductor devices and methods of surface treatment of semiconductor devices are disclosed. Roughness (6) is formed on the surface of a III - V group compound semiconductor to prevent total reflection, and a SiNx film (7) is formed on the rough surface (6). The surface roughness makes it possible to increase external quantum efficiency, and bond strength is increased because the SiNx film (7) is formed on the surface roughness. As a result, detachment of SiNx film (6) is prevented, moisture resistant properties are improved, and the service life of the LED incorporating the semiconductor is extended by preventing oxidation.

Title: Brake apparatus with blind cable installing means.
Inventor: BOYER BILLY G
IPC: F16D65/28
Filed: 1989-08-30
Abstract: A parking brake assembly of the blind-cable-connection type including a backing plate containing an opening, a helical guide spring arranged to guide a flexible resilient inner cable member toward a ramp surface on a parking brake lever for the blind connection to the inner cable member to the lever, characterized in that the angle of inclination of the ramp surface relative to the cable axis is contained in a plane that is both parallel with the longitudinal axis of the lever and that is inclined at an acute angle relative to the axis of the inner cable member. This construction permits the parking brake lever to be simply and economically formed from a blank of flat metal stock, the cable-retaining slot being defined by a slot contained between bifurcated portions of the ramp surface. The helical guide spring includes portions having tightly wound turns, thereby to assist in connecting the spring with the backing plate and/or with the parking brake lever.

Abstract: Les pertes de ventilation dans un frein hydrodynamique (1) sont réduites par le montage de déflecteurs variables (2, 20) entre le rotor (3) et le stator (4). Un ou plusieurs déflecteurs (2, 20) de section angulaire comportent une branche annulaire (21) faisant saillie radialement vers l'intérieur. Au ralenti, lorsque l'huile a été évacuée du frein (1), ladite branche annulaire sépare les chambres toroïdales (31, 41) dans leur région extérieure. Une branche cylindrique disposée dans le sens axial est adjacente à la paroi intérieure (52) d'une chambre (5). Lorsque le frein hydrodynamique (1) est en service, c'est-à-dire rempli d'huile, le bord frontal (29) de la branche (21) faisant saillie radialement vers l'intérieur est situé derrière les chambres toroïdales (31, 41). Si il n'y a qu'un seul déflecteur (20) qui recouvre la périphérie entière de la région extérieure des chambres toroïdales (31, 41), on obtient l'élasticité appropriée en pratiquant des fentes (23, 28) dans la branche annulaire (21) qui fait saillie radialement vers l'intérieur. L'actionnement dans la position terminale radialement vers l'extérieur et vers l'intérieur s'effectue par un dispositif d'actionnement (6, 60). Un mode de réalisation particulièrement avantageux comprend une unité pistons-cylindre (60) avec deux pistons (61), un dispositif entraîneur sur les pistons et des entraîneurs sur le déflecteur (20). La position intérieure est atteinte au moyen de ressorts (62) et la position extérieure au moyen de la pression d'un fluide hydraulique dans une chambre de pression (63) entre les deux pistons (61).

Abstract: A method for pretreating the surface of a medical device, and of applying a polymer coating, in order to apply a biological coating in a further step, uses the plasma polymerization technique or the plasma grafting technique. A functional monomer, i.e. a monomer with a functional group, or a mixture of a pure monomer and a substance able to provide the required functional groups under spark discharge or under the influence of charge carriers, results in a polymer coating with free functional groups, which may react with the biological coating, thus providing optimum adhesion of the biological coating. The process is carried out in a pressure-tight chamber (39) with an inlet (48) for the functional monomer under low pressure and electromagnetic radiation provided by a radiation source (45).

Abstract: The invention relates to a method and a device for testing and supervising majority votes in a multiplane digital time selector with essentially identical equipment in each of at least three planes (A,B,C) working in parallel. An incoming data flow is distributed to the planes and is allowed to pass through the equipment in each of them and gives rise to outgoing data streams. These outgoing data streams are compared to each other and a majority voted outgoing data flow based upon the comparison is delivered from the unit. 
     An error is periodically introduced in accordance with a predeterimed pattern in the three planes and the data streams arriving at the majority vote and the majority voted data flow are compared. If an error is then found in any of the data streams an alarm is emitted. 
     If an alarm (LARM1) is expected that has been caused by an error introduced in accordance with the predetermined pattern, this alarm is identified based upon knowledge of the predetermined pattenr in order to distinguish from alarms, which result from errors not introduced in accordance with the pattern.
