Abstract: A disk playback device comprises a memory for temporarily storing data from a pickup and outputting the data as delayed by a predetermined period of time, manual keys, and a system control circuit for detecting the playback end of a disk from the playback data from the pickup. The memory has connected thereto an erase circuit for erasing data remaining in the memory. The system control circuit produces different flag values in a first case wherein the control circuit detects the disk end to terminate playback of the disk and in a second case wherein the user manipulates one of the manual keys to terminate the playback. A memory control circuit is connected to the memory and the system control circuit. In the first case, the memory control circuit inputs to the memory playback data of another disk replacing the disk as continued from the data remaining in the memory. In the second case, the circuit inputs to the memory the playback data of another disk replacing the preceding disk after the data remaining in the memory is erased by the erase circuit.

Abstract: Novel cluster nozzle designs useful for the formation of atomized sprays of fine liquid droplets in a continuous gas phase are described. A plurality of individual gas-liquid mixing zones communicate with a common source of liquid and a common source of gas to form gas-liquid mixtures for spraying from individual orifices in the nozzle. An improved uniformity of spray pattern is attained, as well as the ability to effect a greater liquid output from the nozzle through the use of larger size or numbers of orifices, while retaining very uniform sprays, by effecting a degree of premixing of liquid and gas before passage to the individual gas-liquid mixing zones.

Abstract: The present invention relates to a new frame support that prevents implement frames and parts from experiencing high forces and instead, transmits the forces through the ground working tools down to the ground. The frame support can be used in conjunction with the suspension system of any implement adapted for travel over the ground and preferably, the invention is used in conjunction with an agricultural packer. The packer may be of any size, but typically is of a five section configuration. In the preferred embodiment, the frame support is a rigid protrusion fixed to the packer frame above the packer coil. The frame support could also be a flat plate, or a rolling element. The frame support is adapted to contact the packer coil during the wing up and wing down operations of the implement. When the frame support and the packer coil contact, the high forces incurred during the wing up and wing down operations are transmitted through the frame support and packer coil down to the ground. In this way, the packer coil subframe does not experience these high loads. The packer coils are preferably mounted to the forward lateral member of each frame section, alternating between being mounted behind the lateral member and being mounted in front of the lateral member. Another embodiment would be to mount the packer coils to the frame alternating between the forward and rearward lateral frame members. Alternately, the packer coils could be mounted to the implement frame in any fashion deemed suitable. In another embodiment, the individual packer coils could be replaced with a gang of packer coils for mounting to the frame.

Abstract: A recombinant baculovirus, which produces a recombinant polyhedra made up of a baculovirus polyhedrin (PH), a Bacillus thuringiensis crystal protein (CP) and jellyfish Aequorea ~ victoria green fluorescent protein (GFP), is constructed by introducing a transfer vector carrying a fusion gene encoding a fusion protein in which the PH, the CP and the GFP are directly linked from N-terminal to C-terminal, in sequence, and a wild-type baculovirus into an insect cell, simultaneously, and culturing the cell. This baculovirus transfer vector pColorBtrus is constructed by synthesizing the GFP-coding DNA fragment from plasmid pGFP, the PH gene from wild-type Autographa californica Nucleopolyhedrovirus, and aCry1Ac gene from plasmid pPN6.6 carrying a Bacillus thuringiensis Cry1Ac gene by polymerase chain reactions, and inserting first the GFP-coding DNA fragment and the PH gene in baculovirus expression vector pAcUW31 in such a way that the 5'-end of the GFP-coding DNA fragment is linked to the 3'-end of the PH gene and then, the Cry1Ac gene between the PH gene and the GFP-coding DNA fragment. The recombinant virus can kill insect pests with high pathogenicity within a short time, and is equipped with a monitoring device for infected insects, so that it can be prevented from being overused.
