Abstract: In a process for the treatment of refuse, especially bio waste, wet waste, tailings and industrial waste, for the anaerobic fermentation of its organic components of biological origin, a readily dehydratable suspension of the organic substances of biological origin is first prepared, in a pretreatment stage, by mechanical treatment with selective dissolution and disintegration of the organic substances of biological origin, in which process, as a function of the selected solids concentration, the action of fluidic forces is controlled in such a way that the organic foreign substances of non-biological origin are not subjected to any substantial comminuting stress before they are separated at the end of the pretreatment, and in which process organic foreign substances of non-biological origin are separated off. The suspension is subsequently converted by means of an anaerobic fermentation process to give bio gas and compost-like recyclings. For the gentle treatment of solids contained in the crude waste in the pretreatment step, the speed of the running wheel 14 of the dissolution container 13 of the apparatus according to the invention is controlled as a function of the solids concentration, which results in a high degree of effectiveness and simultaneously in noticeable energy saving. <IMAGE>

The hardness measurement comprises: calculating the average resonance frequency bared on the measured frequency values; measuring the hardness values corresponding to the average resonance frequency; and obtaining a formula between the measured hardness values and the average resonance frequency by using regressing analysis.

Title: Method and its apparatus of electronic auto sing scoring
Inventor: CHO KIL-WAN
IPC: G10K15/00
Filed: 1993-05-10
Granted: 1996-10-10
Abstract: The apparatus is for scoring singing automatically by considering the musical interval and the beat. The apparatus comprises the steps of: amplifying the song signal received from a mike; comparing the similarity in the beat between the song amplified and the background music; comparing the similarity in the musical interval between the song amplified and the background music; scoring the singing by the comparison data received from the previous steps.

Abstract: 차량통과 검출시스템은 질문기 어셈블리와 수동 응답기로 이루어진다. 하나는 차량에 의해 지지되고 다른 하나는 트랙에 의해 지지된다. 질문기 어셈블리는 연속적으로 동작하는 저주파수 및 중간 주파수 전송기를 포함한다. 전송기는 차량의 주행시 안테나에 대해 응답기에 의해 횡단되는 사전설정된 영역을 향하는 각각의 안테나를 구비하며, 응답기가 영역에 위치할 때 응답기의 특성에 응답하는 유니트를 포함한다. 응답기는 중간 주파수회로를 제어하는 저주파수 수신회로를 구비한다. 두 회로 모두 동조 복사회로를 구비하며, 저주파수 회로에서 발생되는 저주파수 신호는 저주파수의 레이트에서 응답기의 중간 주파수 동조회로를 단락시키는데 사용된다.
