  • Patent number: 6440420
    Abstract: The present invention relates to a method for extracting the oleaginous substances from sporoderm-broken Ganoderma spores using SCF—CO2. The method contains the steps of: (1) inducing germination of Ganoderma spores by incubating the spores in a nutritional solution; (2) activating the Ganoderma spores by placing the germination-induced spores in a well ventilated culture box kept at constant temperature and humidity; (3) breaking the Ganoderma spores by a mechanical means to obtain the sporoderm-broken spores; and (4) extracting the oleaginous substances from the sporoderm-broken spores using a supercritical fluid—carbon dioxide (SCF—CO2) extraction method. The preferred supercritical conditions include 5 M to 60 M Pa of pressure; 32° C. to 85° C. of temperature; and 5 kg/h to 80 kg/h of flow capacity rate. The total extraction time in SCF—CO2 is between 0.5 hour to 6 hour.

  • Patent number: 6407208
    Abstract: Chimeric proteins containing a cellulose binding domain (CBD) situated between two independent desired proteins of different lengths can be contemplated for use in a wide range of applications. In addition to its affinity to cellulose due to the presence of the CBD, various properties can be adopted to the chimeric protein by means of introducing the desired proteins upstream and downstream of the CBD. For example, a chimeric protein is produced in Escherichia coli in large quantities by joining a thioredoxin, a CBD and a short peptide composed of 3 amino acid (i.e., Arginine-Glutamate-Asparate). This chimeric protein can be further purified in simple steps and added to cell culture to enhance cell attachment to a surface made up of cellulose.

  • Patent number: 6398217
    Abstract: A gaming machine has a display arrangement for displaying symbols that are related to a game, and a controller that determines in response to a predetermined input signal whether or not the game condition will be transferred to a specified game condition that is advantageous to the player and controls the display arrangement to display a display mode corresponding to the result of the determination. The display mode includes a special symbol for informing that the game condition is transferred to the specified game condition by showing a predetermined stop state when a symbol variation is stopped, and a predictive symbol for predicting the stop state of the special symbol. The predictive symbol is provided as plural kinds of symbols having respective relationship. The gaming machine can provide to a player an indication of the possibility to transfer to a special game condition depending on the meaning of the relationship of the symbols that are displayed.

  • Patent number: 6392564
    Abstract: This invention relates to a system for motor vehicles to monitor and automatically report to authorities aggressive driving behavior of other vehicles. The camera 10 takes images from the rear view of the vehicle 14 and preferably also from the front. For example, when a vehicle 14 is at a certain MPH and is being followed too closely by another driver (for an extended period of time—ten seconds or more) this event can trigger the system to capture and transmit the rear view images of the offending vehicle. These images are then uplinked to the local law enforcement agency that in turn will determine whether or not a citation or ticket should be automatically mailed to the offender. If the offending driver continues to harass the driver with the system and in doing so drives past the victim, similar images are captured from the frontal view of the vehicle.
