Abstract: 본 발명은 2장의 탄성을 지닌 절연체로 된 평판을 평행상태에서 일정간격으로 맞붙이고, 각 평판의 대향면에 전극을 설치하는 구성으로한 감압센서를 구비하여, 피측정물의 하중을 하중지지수단에 의하여 감압센서에 걸리게 됨에 따라, 평판의 휨에 의한 각 전극간 거리의 변화에 따른 정전용량의 변화를 검지하여 중량을 검지한다. 또, 이 감압센서의 전극을 간극을 포위함과 동시에 이 간극내의 기체의 출입하는 구멍을 설치한다. 나아가서 감압센서의 표면에 먼지나 결로의 발생에 의한 누출전류의 영향을 없애기 위하여 표면을 소수성물질로 피복한다. 이에 따라 온도변화나 습기의 영향이 없이 정확히 측정할 수 있다. 
     또, 감압센서에의 가압은 하중지지수단의 하중을 가압부재를 개재하여 감압센서의 소정위치를 소정면적으로 가압함과 동시에, 가압부재의 형상은 감압센서에 접하는 부분의 면적을 하중지지수단에 대면하는 면적보다 크게 한다. 나아가서 감압센서의 지지는 감압센서의 감압할 수 있는 부분 이외에서 지지함에 따라 정확히, 안정한 중량을 측정할 수 있다. 또, 과대한 하중으로부터 감압센서를 보호하기 때문에 감압센서의 평판의 휨보다 큰 변위를 지닌 탄성체를 개재하여 하중이 감압센서에 걸리는 구성으로 하여, 탄성체가 일정한 변형이 발생하였을때에 동작하는 변위규제수단을 설치하는 구성으로 한다. 이에 따라, 작은 변위인 감압센서를 과대하중으로부터 보호할 수 있다. 이와같이 정확하고 안정한 중량검출이 가능하게 되어 과대하중중에 대하여도 파괴되는 일은 없었다.

Abstract: A  photosensitive  resin  compsn.  is  prepd.  by  mixing  a naphthoquinone diazide cpd. and a novolac resin  with  0.3-5  wt.% cpd. of formula (I) and 0.3-10 wt.% cpd. of  formula  (II)  as  an additive for improving a photosensitivity. In  the  formulas,  R1, R2, R3 and R4 each H or halogen; R5 is H or methyl; R6 is H or CH; R7, R8 and R9 are each H, OH, methoxy or sulfoxy. The cpd. (I)  is pref. phthalic anhydride or tetrachlorophthalic anhydride, and the cpd.  (II)  is   pref.   7-hydroxycumalin,   6,7-dihydroxycumalin, 5,7-dimethoxycumalin, etc. The  compsn.  is  used  for  forming  a positive image by coating a pre-sensitized aluminium plate.

Title: Preparation of strong beta-aluminum
Inventor: FRANKLIN RUFUS M
IPC: C04B35/10
Filed: 1989-02-04
Granted: 1997-06-17
Abstract: Seeding of beta type alumina compositions in which the alumina in the raw batch is microcrystalline boehmite results in significant increase in hardness, density and strength, as compared to unseeded beta alumina, when fired under similar conditions. The method comprises providing a selected beta alumina composition including a microcrystalline boehmite gel, an oxide or a precursor of an oxide of sodium, potassium, lithium, magnesium, or calcium, and submicron seed particles of beta alumina or alpha alumina, said seed particles being present in an amount of at least 0.1% by weight of the final solids content of said body, shaping said gel and drying and firing at a temperature of from 1200 DEG C. to 1500 DEG C., whereby the body is converted to beta alumina, said seed particles being present in said gel in an amount at least equivalent to 10<6> particles per cubic centimeter of finished, fired, product.
