Title: Receiver for digital mobile communications
Inventor: TAKAMI TADAO
IPC: H04B7/26
Filed: 1993-08-30
Abstract: ABSTRACT OF THE DISCLOSURE  A received digital phase-modulated signal is converted by a first frequency converter 13 into a first intermediate-frequency signal, which is applied to a first intermediate-frequency filter 22 which approximates a square-root Nyquist cosine roll-off characteristic and in which intersymbol interference and interference of adjacent-channel signals are suppressed.  That is, the first intermediate-frequency signal is subjected to shaping of its spectrum and channel filtering. The first intermediate-frequency filter 22 is formed by a monolithic crystal filter which utilizes the fundamental resonance mode of an AT-cut crystal element.  The output from the first intermediate-frequency filter 22 is converted by a second frequency converter 16 to a second intermediate-frequency signal.  The second intermediate-frequency signal is applied to a second intermediate-frequency filter 23 of a band pass or low-pass characteristic, wherein noise such as a leakage signal of a second local oscillator 15 is removed from the second intermediate-frequency signal.  The output from the second intermediate-frequency filter 23 is supplied to a limiter 18 and thence to a demodulator 19.

Title: Method and apparatus for the continuous manufacture of chip boards
Inventor: BIELFELDT FRIEDRICH B
IPC: B27D3/04
Filed: 1994-01-17
Abstract: ABSTRACT   The invention relates to a method for the continuous production of chipboard, fibreboard, plastic board and plywood. The method makes use of a continuously operating press having flexible continuous steel bands transferring the pressure and drawing the feedstock through the press. The bands are carried over driving drums and idler drums around the press table and press ram and are backed against the press table and press ram with and adjustable press gap by accompanying roller rods guided with their axes across the band's direction of movement. The compression angle of the entry gap is made variable by an adjusting system. The compression of the feedstock in the entry gap takes place in two stages, a light compression being set in the first stage from 0.5° to heavy compression up to about 5° from the horizontal, and a heavy compression being set in the second stage from about 7° up to a pressure relief of about 1.0° from the horizontal. The first transition between the two stages is set convexly or concavely and the second transition between stages is likewise set convexly or concavely. The invention relates also to an apparatus for carrying out the method.

Title: Hingeless enclosure for a display system
Inventor: HUAT TEO K
IPC: G09F15/00
Filed: 1994-06-14
Abstract: ABSTRACT       HINGELESS ENCLOSURE FOR A DISPLAY SYSTEM   The present invention discloses a hingeless assembly for a protective enclosure incorporated as part of a modular display system. The protective enclosure features a main frame and an open face panel frame. While the main frame and the open face panel frame are assembled from standardized extrusions and joints, an elongated cylindrical bead along one of the external edges of the main frame and a semi-cylindrical elongated groove along a corresponding edge of the open face panel frame are slidably fitted over one another to form a modular enclosure. A gasket is disposed along the hingeless assembly to weather-proof the enclosure. The hingeless assembly of the enclosure not only allows the open face panel to be opened for easy access, but also seals the interior of the display system from the elements when the open face panel is closed. As various components of the present invention are standardized and interchangeable, economy of scale in manufacturing the enclosure is achieved notwithstanding the myriad geometric configurations of display systems.
