IPC: C08K5/25
Filed: 2001-08-27
Abstract: An additive that is used in conjunction with certain dibenzylidene sorbitol-type (DBS) clarifiers and acid scavengers within polyolefin resins to reduce the release of aldehydes from polypropylene material is disclosed. Hydrazides have been shown to be effective at removing residual aldehyde from polyolefins, such as polypropylene. This function can be accomplished with a minimal impact on optical transparent properties imparted to the polypropylene by the clarifying agent. The net effect is an improvement in the organoleptic performance of resins containing clarifiers, and a reduction in the UV-absorbing extractables. Particularly, adipic dihydrazide, when co-compounded into polypropylene homopolymer with 4-methyl DBS, improves the organoleptic performance of the clarifier. Incorporation of dihydrazides into polypropylene pellets reduced air-released aldehyde by nearly 100%.

Abstract: 本発明は、絵付成形物品及び該物品の形成方法を提供する。本絵付成形物品は、ポリマー部分の表面に接着した基体材料を有するポリマー部分を含む。基体材料は、例えば微細繊維または布帛としてよい。幾つかの実施例においては、ポリマー部分は、発泡体、特に微孔質ポリマー材料としてよい。本物品は、発泡剤とポリマー材料との混合物を、基体材料を内部に配置したモールドキャビティ内に射出して、その結果、基体材料がモールドキャビティの壁に押し付けられるようにすることで形成される。発泡剤は、特定の好ましい場合には超臨界流体であり、ポリマー材料の粘度を低下させ、従って、射出圧力及び温度の低下を可能にする。射出温度及び圧力の低下は、加工の機会を広げ、基体材料の選択における柔軟性を増大させ、従来の方法において時々使用されるバリヤー層の必要を無くすことができる。本方法を使用して、様々な絵付成形物品を製造してよい。

Abstract: An array boundary checking method is disclosed for providing hardware based array boundary checking in a Java environment. During the first machine cycle of a current array access command, an array reference value is loaded into a system-data address controller and an array boundary checker. Next, during the second machine cycle of the current array access command, an array index value is written to the system-data address controller and the array boundary checker. Also during the second machine cycle of the current array access command, a maximum array index value is read from the Java array and written to the array boundary checker. The array boundary checker utilizes these values to determine the validity of the current array access command. Finally, during the third machine cycle an array value is accessed in memory. In the present invention the array value is only accessed when the current array access command is valid.

Abstract: A half duplex radio transceiver comprises a transmitter ( 100 ) and a low IF receiver ( 200 ). The difference between the transmit frequency and the receive frequency is equal to the low IF. A common frequency generator ( 300 ) is shared between the transmitter and receiver without needing to be retuned. An upconversion signal at the transmit frequency is used for down conversion in the receiver. Transceivers at opposite ends of a communication link, such as in a master/slave network, have their transmit and receive frequencies interchanged. Optionally a transceiver may be configurable to either form e.g. as either a master of a slave station. Channel sensing for Carrier Sense Multiple Access (CSMA) may be performed on the transmit frequency without retuning the receiver.
