Title: Improving method for smoking flavor of leaf tobacco stock and leaf tobacco stock improved in smoking flavor
Inventor: ITO JOJI
IPC: A24B3/12
Filed: 1994-07-07
Abstract: PURPOSE:To provide the subject simpler and more economical method for improving smoking flavor, and to obtain a leaf tobacco stock improved in smoking flavor. CONSTITUTION:A treatment tank 19 is first encapsulated with a leaf tobacco stock. Second, valves 22, 26 are closed. Then the treatment tank 19 is injected with carbon dioxide by a pump 16 from a tank 11 via heat exchangers 15, 17. The temperature of the carbon dioxide stands at 0-50 deg.C. The carbon dioxide is fed until the inside of the tank 19 is pressurized to a level of 35-100kg/cm<2>. At this specified elevated pressure level, the tank 19 is maintained for 10-60min. As a result, the flavor ingredient in the cells inside the leaf tobacco stock 20 is leached into the carbon dioxide. Then, a valve 18 is closed, the valve 22 or 26 is opened to gradually decrease the pressure inside the tank 19 to the atmospheric pressure. Thereby the flavor ingredient dissolved in the carbon dioxide is condensed on the surface of the leaf tobacco stock 20. The flavor ingredient is localized on the surface of the leaf tobacco stock 20 by this method.

Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a rectifier circuit for general purpose inverter in which generation of harmonics is suppressed while improving the power factor through simple circuitry and the size can be reduced while facilitating connection. SOLUTION: The rectifier circuit for general purpose inverter principally comprises a PWM rectifier circuit and a control circuit 9' turns an IGBT constituting the bridge circuit 8' in the PWM rectifier circuit on/off to bring the differential voltage between an output voltage Vdc and a target voltage Vdc* to zero based on a pseudo sine wave generated from the output voltage va of a rectifier, a signal based on the differential voltage and an input current detected by an AC current detector 17. The zero differential voltage is applied to dead time compensation circuits 22, 23. Consequently, on/off timing of the IGBT can be controlled while suppressing error to a command value.  The pseudo sine wave generating circuit comprises an operational amplifier for detecting the input current immediately after turn on power and delivers the phase of a detected sine wave as the phase of a power supply voltage Vs.

Title: Backup device
Inventor: HASHIMOTO MASAYUKI
IPC: F04F1/06
Filed: 1983-08-29
Abstract: PURPOSE:To prevent inconvenience caused by stoppage of steady flow pump due to power interruption, by feeding compressed air from a pressure source into an auxiliary tank upon stoppage of water transportation pump thereby discharging water from the backup tank. CONSTITUTION:Under normal condition, a water transportation pump 9 will cause steady flow through a check valve 8 into the system to fill the backup tank 6 with water. Upon stoppage of pump due to power interruption, a valve 7 will open automatically to flow compressed gas from a pressure source 13 into the backup tank 6 thus to pressurize the inside of tank. Consequently, the water in the tank will flow into the steady flow transportation pipe 10.
