Title: Pager receiver comprising a message detector energized only at pertinent time slots
Inventor: WADANABE HIROSHI
IPC: H04W88/02
Filed: 1983-01-20
Granted: 1986-09-25
Abstract: In a pager receiver(12), a reception controller(21), is kept operable when a switch(22) is closed. A transistor(31) energizes a receiver part(16,17) at the begining of a call code part of a received calling signal. If a calling code for that receiver is detected at a certain call time slot of the call code part, the transistor keeps the energization until the end of that the call code part and again energizes the receiver part during a message time slot corresponding to that calling time slot in a following message code part.

Title: Ac elevator control apparatus
Inventor: NOMURA MASAMI
IPC: H02P27/08
Filed: 1983-02-04
Granted: 1985-11-06
Abstract: This invention improves the AC elevator control apparatus. UP to now, the inverter is protected against a restoration power which is generated at the DC part of inverter, connected to motor, by means of the restoration power inverter which convert the restoration power to AC power.  But this device is expensive and dissipates the power wastefully.In this invention, the drawbacks are covered by the technique that the restoration power is supplied with the control apparatus by means of turn on the first switch when DC voltage of inverter is over the first reference value.

Abstract: 본 발명에서의 수직 이착륙 항공기 상의 활주 착륙 기어 시스템을 대체할 수 있는 신속 변경 휠 착륙 기어 조립체(10)가 제공된다. 휠 착륙 기어 시스템(10)은 항공기의 아래쪽에 활주 착륙 기어를 장착하기 위해 사용되는 새들 구조(12, 14)에 장착되는 한 쌍이 짧고, 이격된 가로 튜브(20, 22)에 부착되는 한 쌍의 이격된 전후방 튜브(16, 18)를 구비한다. 전후방 튜브(16, 18)는 완전하게 선회하는 앞바퀴(26)를 장착하기 위한 전방 단부에 함께 연결된다. 메인 기어 휠(30, 32)은 후방 가로 튜브(22)에 인접한 전후방 튜브(16, 18)에서 측방으로 연장하는 캔틸레버 방식 착륙 기어 레그(34, 36)에 장착된다. 착륙 기어에 가해지는 착륙 하중은 탄성스프링(25), 기어 레그(34, 36)와 후방 가로 튜브(22)의 휘어짐, 전후방 튜브(16 18)의 비틀림 또는 이들 작용의 조합에 의하여 흡수될 수 있다. 착륙 기어 조립체(10)의 전후방 튜브(16, 18) 및 가로 튜브(20, 22)와 함께 피로 응력을 감소시키기 위해서 착륙 기어 조립체(10)의 탄성 스프링(25)을 사용하였다. 휠 착륙 기어 조립체(10)는 기존이 항공기 새들 구조에 장착디고, 또한 저렴한 비용과 용이한 유지보수를 포함하는 활주 착륙 기어 시스템의 여러 가지 바람직한 특성을 존속시키도록 설계된다.

Abstract: A Zinc (Zn) doped P-type gallium arsenide (GaAs)  polycrystal is prepared by  boat  growth  method.  The  method  comprises  (1) separating and charging the pure zinc with gallium material into a gallium-charging   boat   and   arsenic   material     into     an arsenic-charging boat, (2) growing  the  p-type  gallium  arsenide polycrystal by rate of  1  cm/hr  without  zinc  element  loss  by heating the gallium charging boat to  1,200-1,260  deg.C,  and  by heating the arsenic charging boat  to  600-630  deg.C.  Espacially volatile zinc element is  alloying  with  gallium  to  reduce  the evaporation pressure of zinc to less than 1/100.
