Granted: 1990-04-04
Abstract: Air exhausted from a heating room (14) is firstly heated to the predetermined temperature, and heated again for a constant time equal to the alpha+ the preheated time.  The micro wave oven senses a temperature (U.) of air to be inflowed to the heating room and continues to sense the air temperature (U1) at the interval of sampling period until the inflowed air temperature (U1) reaches to the last air temperature (U1-1).  When the temperatures (U1)(U1-1) are equal, the system senses the exhausted air temperature (V1), calculates the temperature increment ( T) and the temperature difference ( V), and then calculates the compensated temperature increment ( T) so that the first and second heating operation are achieved.

Abstract: Nonwoven fibrous elastomeric web material, including absorbent webs and fabric web material, and methods of forming the same, are disclosed. The elastomeric web material is a hydraulically entangled coform or admixture of (1) meltblown fibers, such as elastic meltblown fibers and (2) pulp fibers and/or staple fibers and/or meltblown fibers and/or continuous filaments, with or without particulate material; such coform can by hydraulically entangled by itself or with other materials, including, e.g., super absorbent particulate material. The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the use of shorter staple or pulp fibers. The hydraulic entangling technique provides a nonwoven fibrous elastic material having increased web strength and integrity, and allows for better control of other product attributes, such as absorbency, wet strength and abrasion resistance. A smooth surfaced and/or highly absorbent elastic web material, with isotropic strength and recovery in both machine- and cross-directions, can be provided according to the present invention.

Abstract: 설정된 깊이까지 지면(A)속으로 동시에 상호중심거리(C)와 평행하게 굴착하는 침식유니트(2)와 액상화 유니트(3)의 구성요소를 각각 형성하는 드릴수단(2b 및 3b) 갖춘 회전하는 액상화헤드(3a)와 회전하는 침식헤드(2a)를 사용하여 지면수준으로부터 입자가 큰 물질 안에 콘크리트구조를 짓는 방법. 침식헤드(2a)는 팽창된 굴삭공(4a)을 그라우팅하는 압력과 침식된 입자가 큰 물질(E)의 동시제거될 때 액상화물질, 즉, 콘크리트를 공급하는 동안 액상화헤드(3a)가 침식헤드(2a)에 관해 약간 밑으로 움직여 상승됨과 동시에 굴삭공(4)벽이 침식 되는 동안 상승된다.

Title: 광자기 기록장치
Filed: 1991-01-31
Granted: 2001-03-02
Abstract: 기록 광에 응답하여 광자기 기록 매체에 기록 광빔이 조사되어 광자기 기록 매체에 피트가 형성되고, 광자기 기록 매체상의 피트에 재생 광빔이 조사되어 기록정보를 재생하는 광자기 기록 장치 및 광자기 재생 장치에 있어서, 기록 신호 중에서 광자기 기록 매체 상에 피트가 형성되는 광조사 주기에서 기록 광빔이 간헐적으로 방사되기 때문에, 광자기 기록 매체 상에 거의 원형 형상의 피트가 형성될 수 있고, 그로 인해, 광자기 기록 매체 상에 고정밀도로 정보가 기록될 수 있다.
