Granted: 1994-03-23
Abstract: The functions of two virtual opening systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Granted: 1993-07-30
Abstract: There is provided a method of digital Automatic Gain Control (AGC) in a receiver having limited dynamic range, particularly for discontinuous signals. The method is characterized by detecting the level of a received and AGC'd discontinuous signal, comparing the level of the AGC'd signal relative to the dynamic range of the receiver, and adjusting the AGC to establish a desired relationship between the AGC'd signal and the dynamic range limitation. There is also provided a method of handoff in a TDMA cellular-type transmission system utilizing this method of AGControl. The method for Automatic Gain Control (AGC) of discontinuous signals in a receiver having limited dynamic range is further characterized by: digitizing (A/D) a received and AGC'd discontinuous signal and converting the digitized samples to a power sample to sense the power of and detect the level of the signal, comparing the level of the AGC'd signal relative to the dynamic range of the receiver; and coarsely-adjusting by either progressively attenuating the signal until it falls within the dynamic range of the receiver or by progressively gain-amplifying the signal until it falls within the limited dynamic range of the receiver and finely-adjusting the AGC of the received signal until optimum use of the full (albeit limited) dynamic range of the signal processing stages is about 6-12 dB below maximum to establish a desired relationship between the AGC'd signal and the dynamic range limitation. <IMAGE>

Abstract: 본 발명에 따라 일반적으로 말하자면, 바 클램프는, 
     클램프는 고정조오와 고정조오에 대향되는 가동조오를 포함한다. 가종조오는 슬라이드 바에 대하여 일측단부와 연결되었고, 고정조오를 향하여 이동가능하게 하고, 고정조오로부터 멀리 떨어지게 한다. 
     트리거핸들그립의 작동에 의한 한 방향의 구동수단은, 
     슬라이드 바와 분리 가능하게 연결되었고, 고정조오를 향하여 구동조오를 전진시킨다. 한방향의 구동수단은 슬라이드 바를 이동할 수 없게 했고 구동조오를 고정조오로부터 멀리 떨어지게했다. 구동조오의 방향운동은 한 방항의 구동수단이 분리되 수동적으로 성취할 수 있었다. 
     슬라이드 바와 결합하도록 엇갈려 있는 제일 제동레버는 제일레버가 슬라이드 바로부터 분리될때를 제외하고는 구동조오의 역운동을 고정조오로부터 멀리 떨어지게 하는 것을 방해한다. 
     그러므로 조오의 되돌림 운동 때문에 일측 방법의 구동 수단과 제일 제동레버 양쪽 다 분리될 필요가 있다. 
     트리거핸들은 슬라이드 바의 표면과 결합된 제이레버를 구동 함으로써 슬라이드 바를 전진시키고, 제이레버가 고정조오를 향하여 이동시키는 것처럼 로드를 이동시킨다. 
     제이레버는 되돌림 운동 동안 바 표면 위에서 미끄러지게된다. 
     따라서 본 발명의 목적은 개량된 퀵 액션 바 클램프를 구비하는 반면 가동조오가 짧게 그리고 긴 거리를 빠르게 움직이게 하는데 있다. 
     본 발명의 또 다른 목적은 개량된 퀵 액션 바 클램프를 구비함에 있어서, 가동조오가 즉각적으로 정확하게 어떤 위치로부터 전진되는데에 있다. 
     덧붙여 본 발명의 목적은, 개량된 퀵 액션 바 클램프를 구비함에 있어서, 가동조오가 구동핸들의 각 작동에 대한 선택적인 길이의 증감을 전진시킨다. 그러나 본 발명의 또 다른 목적은 구비, 개량된 퀵 액션 바 클램프에 있어서, 구동조오는 클램프가 수직위치로 놓여 있을때 그것 자체의 무게에 의해 움직이지는 않는다. 
     본 발명의 또 다른 목적은 구비된 개량 퀵 액션 바 클램프에 있어서, 클램프 작동은 한손을 가지고 성취할 수 있었다. 
     본 발명에 따르면 구성의 특징과 요소의 조화, 이 이후 구성에 있어서 예증될 부분의 배치를 포함하고, 본 발명의 범위는 청구 범위에서 명시될 것이다.

Title: Fabric softening products based on a combination of pentaery thritol compounds and bentonite
Inventor: PUENTES-BRAVO EDUARDO E
IPC: C11D3/00
Filed: 1992-08-25
Granted: 1999-11-15
Abstract: A fabric softening product is a composition or article that is effective for its fabric softening purpose but preferably excludes ecotoxic quaternary ammonium salt, includes, as a fabric softening component, a PEC, which is an ester of pentaerythritol, an ester of an oligomer of pentaerythritol, an ester of a lower alkoxylated pentaerythritol or an ester of a lower alkoxylated pentaerythritol oligomer, with bentonite, which increases its fabric softening effect remarkably. The PEC is preferably a partial higher fatty acid ester of pentaerythritol or a partial higher fatty acid ester or a pentaerythritol oligomer, the bentonite is preferably sodium bentonite or swellable calcium bentonite, the fabric softening composition is a softergent or a non-detersive composition, both of which may be in solid (preferably particulate solid) or liquid state or form (preferably in aqueous suspension or gel), and the fabric softening article is an absorbent material with bentonite and PEC deposited on it or absorbed by it. Also within the invention are processes for softening fibrous materials of laundry by contacting them with such compositions and/or articles during washing, rinsing and/or drying operations. <IMAGE>

Title: Video rom player system
Inventor: KIM SU-CHOL
IPC: G11B20/00
Filed: 1992-11-23
Granted: 1995-04-17
Abstract: The system provides the various pictures stored in the ROM with the outer ROM controller. The system includes a D RAM controller (40) which outputs the /RAS and /CAS siganls, a ROM memory block (10) which outputs the parallel data, a memory control system (20) which chooses the corresponding ROM (12), an address decoder (30) which outputs the image data in ROM (12), a digital/analog converter (50) which converts the image data of ROM (12) into the analog signal.
