Title: Optical fiber connector and ferrule used for it and production method for ferrule
Inventor: OKAMOTO SHINICHI
IPC: G02B6/38
Filed: 1999-11-25
Granted: 2004-01-27
Abstract: Electroforming is performed in an electroforming bath with a cathode of a metal wire member immersed in an electroforming solution to electrodeposit nickel around the aluminum alloy wire member. The aluminum alloy wire member is removed by dissolution with an alkaline solution from an obtained nickel electroformed product. Accordingly, a nickel cylinder is obtained, which has a through-hole formed corresponding to the wire member. The cylinder is cut into those having a predetermined length. The outer circumference is subjected to cutting based on the through-hole to obtain a ferrule. The inner diameter accuracy of the through-hole of the ferrule is determined by the outer diameter accuracy of the wire member. Therefore, it is unnecessary to perform polishing for the through-hole. The highly accurate ferrule is obtained in accordance with the simple process at low cost. The PC polishing for the ferrule for effecting PC junction of optical fibers is extremely easy, because the ferrule is made of metal. Thus, it is possible to provide a high performance optical fiber connector.

Abstract: The invention is an improved method of generating fine medicament powders suitable for inhalation. A fluid energy mill is used with conventional milling fluids such as air or nitrogen. The milling fluid is treated to have a controlled relative humidity of between 30 % and 70 %. This produces a fine medicament powder with a median particle size below 10 micrometer but with little or no amorphous content generated during milling. Scale formation in the mill chamber is also greatly reduced.

Ladite couche semi-conductrice possède un premier et un second côtés ainsi qu'une première et une seconde extrémités. Le second côté de la couche semi-conductrice est posé sur le second côté de la couche isolante. Le quatrième élément, une source faite d'un conducteur électrique, par exemple l'argent, est en contact électrique avec la première extrémité de la couche semi-conductrice.

Title: Encapsulated optoelectronic devices with controlled properties
Inventor: SCOTT JEFFREY W
IPC: H01L23/31
Filed: 2000-03-24
Granted: 2008-04-15
Abstract: An optoelectronic device, such as a VCSEL, is disclosed whose transmission does not change upon encapsulation by a material such as plastic, epoxy or other suitable encapsulant with a known index of refraction. The surface reflection of the VCSEL surface is very different depending on whether it is terminated in air or the encapsulant, with a much larger reflection in the case of air. It is known that the surface reflection can be made out of phase with the rest of the mirror, effectively increasing the transmission.  The amount of the transmission increase can be adjusted by controlling the thickness of the surface layer. Once the VCSEL is encapsulated, the surface reflection is reduced, and the transmission at the facet is increased but the dephased reflection is also reduced. Depositing a surface layer whose index of refraction is similar to the encapsulant, and adjusting the surface layer thickness correctly, the overall transmission from the laser into the terminating material is unchanged, be it air or encapsulation. As a result, the laser properties such as slope efficiency and threshold current are unchanged upon encapsulation. The same procedure may be applied to devices other than VCSELs such as other types of lasers, LEDs, and resonant cavity photodetectors to achieve encapsulated optoelectronic components with controlled properties that remain unchanged upon encapsulation.

Granted: 2008-02-19
Abstract: An apparatus for processing printed circuit boards including a system for measuring and controlling solder wave height generally comprises conveyor system for transporting printed circuit board through a number of processing stations. The system for measuring and controlling the wave height of solder includes a sensor which is mounted in close proximity to the interface defined between the surface of the solder wave and the bottom surface of the printed circuit board. The sensor is coupled to a micro-controller and the micro-controller is coupled to a pump motor. The pump motor is coupled to a solder bath which generates the solder wave and is controlled to operate at a predetermined speed to maintain a predetermined solder wave height during the process of wave soldering printed circuit boards. The sensor provides a number of voltages to the micro-controller representing the distance between the sensor and the top surface of the solder wave. The voltages are converted into a number of values. The micro-controller includes a comparator which receives the values and compares the values to a predetermined set point to determine whether the solder wave height is too high or too low and the micro-controller further determines whether to respectively decrease or increase the speed of the pump motor.

Abstract: An implant syringe comprises a guide sleeve which has seated therein a syrin ge needle arrangement composed of a syringe needle, a needle holder, a grip member and a preparation receiving member. Said syringe needle arrangement is block ed in an initial state by two spring arms that are cut out from the guide sleeve a nd obliquely project inwards such that they rest on a rear wall of the syringe needle arrangement. When the plunger of the implant syringe is pushed forwards to advance the preparation up to the head end of the syringe, a sleeve which is connected to the plunger abuts on the spring arms and bends them outwards, whereby the syringe needle arrangement can be retracted. The two operations are carried out without changing the position of the hand, thereby simplifying t he handling of the implant syringe.
