Title: 휠체어
IPC: A61G5/10
Filed: 1998-06-02
Abstract: 한쌍의 동륜과, 그 동륜의 앞뒤에 각각 배치하는 캐스터를 차체 프레임에 설치하여 휠체어의 방향을 정지위치에서 회전가능하게 한 휠체어에 있어서, 차체 프레임과 동륜 사이에 차체 프레임의 상부부분에 일단을 요동 가능하게 연결하고, 또한 다른 일단에 상기 동륜을 회전 가능하게 축지지하는 링크부재를 설치하고, 동륜의 회전축은 적어도 앞부분 캐스터가 단차에 다다르기 전 상태에서는 차체 프레임으로의 링크부재의 연결점보다 후방측에 배치되어 있는 휠체어이다. 그렇기 때문에 휠체어의 전진주행시 앞부분 캐스터가 단차에 다다랐을 때, 차체 프레임과 링크부재의 연결점을 중심으로 하여 링크부재가 회동됨으로써 앞부분 캐스터와 동륜의 간격이 좁아짐과 동시에, 뒷부분 캐스터를 지지점으로 하여 차체 프레임의 전방측이 들어올려지기 때문에 단차 상면에 앞부분 캐스터가 올라앉아 단차넘기가 달성된다.

Filed: 2000-05-03
Abstract: PURPOSE: To provide a microwave oven using an inverter power supply of half-bridge type capable of preventing the starting time of a magnetron from becoming long while the dielectric withstand voltage of a booster transformer remains small. CONSTITUTION: Because the primary side of a booster transformer 5 is connected with an inverter power supply of half bridge type, no DC component flows in the primary winding of the booster transformer 5, and its saturate voltage may remain small. The transformer 5 has a core gap 39 consisting of core segments 28 and 29, and because the core gap 39 is positioned on the side with the secondary winding 22, it 22 has a reduced self-coupling coefficient, and the self-resonance frequency on the side with secondary winding 22 is shifted to the high frequency side. This enlarges the resistance of the side with secondary winding 22 and lessens the Q value of self-resonance on the side with the transformer secondary winding 22, so that generation of ringing due to self-resonance can be prevented.

Abstract: 대구경 용 화학 기계적 연마 장치로서, 반도체 웨이퍼의 연마될 표면이 위로 향하도록 진공을 사용하여 테이블에 고정되며, 연마에 사용되는 패드라는 연마포를 스핀들에 부착하고, 스핀들이 하강시 반도체 웨이퍼 표면의 일부면과 접촉하여 웨이퍼 회전과 스핀들의 회전에 의해 반도체 웨이퍼 전면의 균일한 연마가 되도록 한다. 이때, 반도체 웨이퍼는 프로그램에 따라 전후 운동을 진행하여 연마포(Pad)가 반도체 웨이퍼 중심에 닿아 중심 부위의 연마가 용이하게 되도록 한다. 연마액인 슬러리는 스핀들 내부의 공급장치에 의해 반도체 웨이퍼의 연마면 위에 골고루 살포되고, 항상 새로운 연마 입자의 공급으로 균일한 연마가 이루어 질 수 있도록 한다.

Abstract: PURPOSE: To obtain a positive type resist composition for KrF excimer laser having good resolution and a sufficient focal depth width by incorporating a resin which comprises a copolymer containing a hydroxy(α-methyl)styrene units, a styrene unit and a specified unit and increases its alkali solubility under an acid and a specified compound. CONSTITUTION: The resist composition contains a resin which comprises a copolymer containing a hydroxy(α-methyl) styrene units, a styrene unit and a unit of the formula and increases its alkali solubility under an acid and a compound which generates the acid when irradiated. In the formula, R1 is H or methyl and R2 is a lower alkyl. The 1-alkylcyclohexyl group in the unit of the formula is released by the action of the generated acid, the ester part is converted to a carboxyl group and the alkali-insoluble resin is made alkali- soluble after exposure.
