Title: Method of preparing an antibacterial polymer and its application
Inventor: ASAI TAMIO
IPC: A01N37/06
Filed: 1990-07-31
Granted: 2000-09-26
Abstract: A method of preparing an antibacterial polymer and application of the antibacterial polymer obtained by this method. A silver oxide and a thermoplastic copolymer that contains a unit consisting of ethylenically unsaturated carboxylic acid or an anhydride thereof and that can be melted upon heating, are mixed, melted and is kneaded in order to obtain a polymer that exhibits in combination the antibacterial property and the heat-processability or the heat-moldability. By making this polymer present on the inner surface of the packing containers, it is made possible to impart the antibacterial property without deteriorating the flavor retentivity for the contents.

Title: Pulsating infrared radiation source for infrared spectroscopy
Inventor: KANSTAD SVEIN OTTO
IPC: G01J3/10
Filed: 1990-05-22
Granted: 1996-04-23
Abstract: Pulsating infrared radiation source (50), which is so thin as to make its thermally stored energy less than the energy radiat-ed during each pulse. This makes the source cooled by its own heat emission. Such sources have thicknesses commensurate with the wavelengths of infrared radiation. To avoid interference effects, the source's optical thickness may be made to equal a multi-ple of half wavelengths of the desired radiation. With the source mounted in a housing (53), efficient radiative cooling is obtained using windows (54 and 55) to each side. This makes it possible to extract infrared radiation from either face of the source.

Title: Telephone unit
Inventor: GUMB BEVERLEY W
IPC: H04M1/23
Filed: 1992-01-22
Granted: 1996-09-10
Abstract: A planar elastomeric layer located between operating buttons and circuitry in a telephone base. The layer has button actuated regions which project above the plane of the layer to different heights so as to compensate for a change in distance of the outer surface of the telephone base whereby buttons of equal heights project for equal heights from that surface. The inventive concept is useful when requiring, for instance, a convex or concave outer surface to the base, but while still requiring the simple planar concept for the elastomeric layer.

Title: Method of drying a protective polymer coating applied onto a surface of an article from a solution, and device for effecting thereof
Inventor: PEREMYSCHEV VLADIMIR A
IPC: H01L21/027
Filed: 1991-05-08
Granted: 1996-10-22
Abstract: The method and apparatus operate to complete the following stages:  at the first stage the coating is held at room temperature in the time interval of from 20 s to 1 hour, depending on the type of polymer coating.  At the second  stage  the  coating  is  held  at  an  elevated temperature  under  excessive  pressure,  sufficient  for suppressing  propagation  of  microcracks  in  such  time interval so that at reaching the predetermined protective properties the thermodestruction of the polymer coating does not occur.   At the third stage performed is the cooling  of  the  polymer  coating  to  room  temperature. According to the  invention,  the excessive pressure  is built up at the first stage and maintained at the cooling stage.  The present invention may find application in the manufacture of integrated circuits,  as well as for the formation of thin polymer insulation coatings.

Granted: 1997-03-04
Abstract: A food depositing apparatus (10) for depositing hash brown potato strands (34) having varying lengths includes a plurality of depositing assemblies (24). Each of the depositing assemblies (24) includes a plurality of outlets (80). A pump member (17) coupled to the inlets (48) of the depositing assemblies (24) provide pressure to force a potato slurry (14) through the outlets (80) of the depositing assemblies (24). A plurality of rotary valve components (102) are positioned adjacent the cutlets (80) of the depositing assemblies (24). Each rotary valve component (102) includes a plurality of wiper blades (130) which correspond to the outlets. Each wiper blade (130) has a first state that permits the potato slurry (14) to be forced through the corresponding outlets (80) and a second state that stops the flow of potato slurry (14) to create a hash brown potato strand. A conveyor positioned beneath the outlets (80) carries the formed hash brown potato strands (34) to a drier (40). The drier (40) dehydrates the formed hash brown potato strands (34). Changing the speed of rotation of the rotary valve components (102) and/or the size of the wiper blades (130) controls the lengths of hash brown potato strands (34) produced by the depositing apparatus (10).

Abstract: A voice encoder which pauses outputting codewords in accordance with the absence of voice activity.  An input aural signal is divided into frames and inputted to the voice encoder.  The voice encoder has a voice activity detection circuit for determining at each frame whether voice activity is absent or present, a voice encoding circuit, a background noise update judging circuit for detecting a change in the characteristics of the input aural signal, and a control circuit.  If the absence of voice activity is detected, the control circuit causes the frame at that time to be encoded as a background noise frame, and then pauses the operation of the voice encoding circuit.  If the presence of voice activity is detected, the operation of the voice encoding circuit is resumed.  Furthermore, if the voice encoding circuit is not in operation when a change in the characteristics of the input aural signal is detected, the control circuit causes the voice encoding circuit to encode the frame at that time as a background noise frame and then again stop the operation of the voice encoding circuit.
