Abstract: An adjustable dose dispenser having a measuring chamber of constant cross-section defined in a housing wherein an end of the chamber is selectively placed in communication with a reservoir containing flowable material to fill the chamber and with a passage to discharge material from the dispenser, and including a piston movably mounted in the housing and having an end face located in the measuring chamber so as to define the measuring volume between the piston end face and the end of the chamber. A manually operable drive mechanism is movably carried by the housing and has formations thereon operatively engaging formations on the piston so that upon movement of the drive mechanism the piston end face is moved along the measuring chamber to vary the volume thereof and so that dimensional control of the volume of the measuring chamber is determined by tolerance associated with misalignment of the formations on the piston and drive mechanism. The formations preferably are fine pitch gear teeth, and the piston and drive mechanism are installed in the dispenser in a manner such that the total tolerance associated with the volume of the measuring chamber is defined as the circular pitch of the gear tooth, i.e., the maximum misalignment between the gear teeth on the piston and on the drive mechanism.

Abstract: PURPOSE: A method for fabricating a capacitor is provided to increase capacitance with a relatively simplified process. CONSTITUTION: In the method, a gate oxide layer(2) and a polysilicon layer are formed on a silicon substrate(1) where a field oxide layer(20) is formed, and then etched through a photoresist pattern to form a gate electrode(3). Next, the first impurity ions are implanted into the substrate(1) while the photoresist pattern remains. An oxide spacer(7) is then formed on sides of the photoresist pattern and the gate electrode, and the second impurity ion implantation is performed. After that, a planarized layer is deposited over an entire structure and etched back to expose an upper portion of the oxide spacer(7). Thereafter, the oxide spacer(7) is partly removed from the side of the gate electrode(3) by reactive ion etching to form a self-aligned gate electrode sidewall hole. Moreover, the remaining oxide spacer(7) is used for the capacitor with increased capacitance.

Patent KR-100276634-B1 (KR)
Title: 알칼리 전지용 금속 수소화물 전극 및 그 제조 방법
IPC: H01M4/24
Filed: 1993-11-24
Granted: 2001-04-02
Abstract: 알칼리 전지용 메탈 하이드라이드 압축 전극이 개시되며 이 전극은 불규칙한 표면의 도전성 결합층을 형성함으로써 변형되는 통상 매끄러운 표면과, 변형기판에 대해 압축되는 전기 화학적 활성 수소 저장 합금 물질 부착층을 구비한다. 전극을 제조함에 있어서, 상기 기판을 변형시키는 바람직한 방법은 얇은 소결 도전 입자 층을 도포시키는 단계, 전기 화학적 에칭 또는 샌드블래스팅에 의해 표면을 증가시키거나 전기 도금시킴으로써 나뭇가지 모양의 입자 층을 도포시키는 단계를 포함한다. 결합제 없는 활성 분말 물질이 변형기판에 대해 압축된 후, 전극은 어닐링 공정에 의해 열처리 될 수도 있다.
Patent KR-960005522-B1 (KR)
Title: Preparation of litao3 single crystal
Inventor: JUNG DAE-SIK
IPC: C30B29/22
Filed: 1993-12-16
Granted: 1996-04-25
Abstract: The method using a low melt temp. alloy as coolant has several steps in order : inserting the metal ingot to a vacuum casting melting pot ; reducing the press. to vacuum degree in the melt pot, heating the melt pot to dissolve the metal ingot ; heating up the temp. of mold above the melting temp of metal, injecting the melten metal ingot into heated mold ; putting the injected mold above metal bath; initiating the single crystal of molten motal in mold by gradual cooling effect of metal bath which comes from melting itself; finishing the growth of single crystal. This method can get high quality single crystal of casting by natural cooling without water cooling plate.
