Title: Monolithic integrated enhancement mode and depletion mode field effect transistors and method of making the same
Inventor: WOHLMUTH WALTER A
IPC: H01L21/70
Filed: 2004-10-26
Abstract: A depletion mode (D-mode) field effect transistor (FET) is monolithically integrated with an enhancement mode (E- mode) FET in a multi-layer structure. The multi-layer structure includes a channel layer overlaid by a barrier layer overlaid by an ohmic contact layer. Source and drain contacts of the D-mode and E-mode FETs are coupled to the ohmic contact layer. A gate contact of the D-mode and E- mode FETs is coupled to the barrier layer. An amorphized region is provided beneath the E-mode gate contact within the barrier layer. The amorphized region forms a buried E-mode Schottky contact with the barrier layer. An alternative embodiment couples the gate contact of the D-mode transistor to a first layer that overlies the barrier layer, and provides a similar D-mode amorphized region within the first layer. ® KIPO & WIPO 2007

Title: Device for holding a fluidic component
Inventor: GESER JOHANNES
IPC: B05B1/00
Filed: 2004-12-28
Abstract: Special precautions must be taken when maintaining a component under fluidic pressure, if the component consists of hard and brittle material and can be destroyed by locally increased stresses. According to the invention, one such fluidic component, e.g. consisting of silicon or glass, is arranged in an elastomer mould, e.g. consisting of silicon rubber, having a contour that is adapted to the outer contour of the component and to the inner contour of a support. Said elastomer mould is bevelled on the pressure side thereof towards the fluidic component. During the assembly of the support, the elastomer mould is deformed by means of a projection on the counterpart, and subjected to homogeneously distributed inner stress, whereafter the elastomer mould surrounds the fluidic component over the entire height thereof. Said floating support prevents any unacceptable local stress peaks and any deformation of the component. The support is sealed from the fluid, even if the fluidic pressure fluctuates repeatedly from a very small value to several hundred bar. The support is especially suitable for a fluidic component consisting of glass or silicon in a miniature embodiment. Said support is used in the field of medical technology, for example, for a nozzle in a miniature atomiser for producing an aerosol or a mist without a propellant, and for the needleless subcutaneous injection of a liquid containing a medically active substance.

Abstract: 본 발명은 세포의 동결건조 기술을 이용하여 구조적으로 장기간 보관하도록 하는 방법에 관한 것이다. 인간의 동결건조 세포를 장기간 보관하는 기술은 아직 한계가 있지만 본 연구소에서는 구조적으로 장기간 안전하게 보관하는 방법을 먼저 발명했다. 본 발명으로 보관하면 동결건조 세포가 구조적으로 안정화되어 세포 형태학적으로 손상 없이 장기간 보관이 가능하다. 
     보관하는 세포 모델은 인간의 혈구세포이다. 보관을 위해서는 단기간 보관하는 방법과 장기간 보관하는 방법 둘로 나누어 설명한다. 단기간 안전하게 보관하는 방법은 본 연구소에서 이미 특허를 신청한 방법을 사용한다. 37℃에서 15시간 동안 800mM 트리할로즈 버퍼에서 혈구 세포를 배양한다. 이때 세포보호물질은 5 × 10 -4 M L-ascorbic acid, 5 × 10 -5 M lipoic acid, 5 × 10 -5 M Melatonin, 3 × 10 -4 M N-actyl-L-cysteine, 10 -5 M δ-tocopherol 그리고 5 × 10 -5 M insulin, 10 -5 M prostaglandin E1을 사용한다.   
     장기간 보관하는 방법은 배양한 세포를 동결건조한 후 글리세롤(glycerol)로 채우는 방법을 사용한다. 15시간 동안 배양한 혈구 세포를 동결건조 버퍼와 섞은 후 5% 적혈구 용적률을 만든다. -40℃까지 분당 1℃의 속도로 냉각을 한 후 -40℃에서 30분간 배양한다. 일차 건조는 30mTorr의 진공에서 7시간 동안 -30℃로 한다. 이차 건조는 6시간 동안 하는데 선반(shelf) 온도는 -30℃에서 50mTorr를 이용하여  20℃로 분당 0.8℃로 증가시킨다. 이후 샘플을 특수제작된 보관용기에 넣고 공기를 제거하고 액체 무수글리세롤로 100% 채워 장기간 보관하게 된다.  
     이 방법으로 기능의 완전한 회복은 연구 과제가 많이 남아있지만 일단은 구조적으로는 안정화되어 반영구적으로 보관이 가능하다. 동결건조 세포를 반영구적으로 보관하는 기술은 우리 일상 생활에서 여러 가지로 유용하게 사용될 수 있다. 장례식장에서 고인을 기억하는 추모용이나 사랑하는 사람을 기념하는 추억용으로 세포를 간직해 보관할 수 있다. 이렇게 일상생활에 유용하게 사용할 수 있는 방법이지만 아직 개발된 적이 없기에 이에 방법과 활용에 대해 특허를 신청한다.

Abstract: A lighting apparatus for a rare gas fluorescent lamp is provided to improve an axial brightness distribution of the rare gas fluorescent lamp by quickly generating a discharge in an axial direction of the rare gas fluorescent lamp. A lighting apparatus includes a rare gas fluorescent lamp(1) and an inverter circuit(100), which applies an AC high voltage to the rare gas fluorescent lamp. A switching circuit(101) converts a DC voltage to the AC voltage by turning on/off switching elements according to a switching element operation signal. A transformer(111) boosts the AC voltage from the switching circuit. A ratio between a lighting period and a black period is controlled, such that a burst lighting is performed. A frequency of the switching element operation signal during at least a portion within a first interval is set to be higher than the frequency of the switching element operation signal during a normal mode. The first interval is measured from a lighting start timing to a lighting completion timing.
