Title: Preservation of regular coffee
Inventor: ISHIWAKI TOMOHIRO
IPC: A23F5/10
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a method of preserving regular coffee which has solved such problems that conventional nitrogen substitution, vacuum packing and use of a specialized valve and oxygen scavenger are carried out to preserve coffee bean or powder, however, these methods have a defect in which a degassing operation called aging is required and a gas release from the valve or a gas release by the action of oxygen scavenger occurs to weaken the fragrance of coffee and these methods aim preservation until the container of regular coffee is opened and are not methods to preserve freshness after opening the container. SOLUTION: A lidded container obtained by attaching a lid having opening and closing properties, pressure resistance and gas barrier properties to a container having pressure resistance and gas barrier properties is used by using an oxygen scavenger for removal of oxygen. Fresh coffee immediately after roasting is packed into the container and the fragrance of coffee is confined in bean or powder by the inner pressure of a generated gas. When the container is closed with the lid even after the opening of the container, the inner pressure rises and the similar effect is obtained. A PET bottle may be cited as the lidded container.

IPC: B23Q17/09
Filed: 1983-11-16
Abstract: PURPOSE:To take out cutting resistance as electric signal to monitor continuously and remotely cutting conditions by interposing a piezo electric element between a throw-away tip and a holder in a cutting tool for a lathe. CONSTITUTION:In lathe working, stress is applied to a throw-away tip 21 of cutting edge in lathe working by cutting resistance to a workpiece 22 to hold a piezo electric element 23 against a holder 24 so that voltage of the piezo electric element produced according to the stress is measured by a voltage measuring apparatus 26 through a lead wire 25. And when the throw-wawy tip 21 is damaged or has the wear of cutting edge, the cutting resistance is abnormally increased compared with the normal cutting case and the voltage is substantially changed by the piezo electric element 23. By measuring this voltage can be monitored abnormalities such as damage and wear of throw-away tip.

Title: Solenoid driving device
Inventor: KASHIWABARA MASUO
IPC: G05B11/36
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To obtain a value near a target control amount from a feedback correction starting time even if there is a change in temperature by deciding the initial value of a feedback correction amount for a solenoid for starting feedback correction based on the feedback correction result of the other solenoid. SOLUTION: For starting electricity conducting to a solenoid SOL 4, if electricity is conducted to, among solenoids SOL 1 to SOL 3, SOL 1 and SOL 2, SOL 2 having a short distance is selected. By performing weighing as a distance is increased for an integration control amount (error integral amount) for the other solenoids to which electricity is conducted, a correction amount is decided. Since the newest integration control amount of SOL 2 corresponds to deviation by a temperature change, the integration control amount is set as an initial value, and a correction amount corresponding to a temperature change is immediately provided. Thus, an error amount at the time of starting feedback correction is reduced to increase convergence for a target current, and a value near a target control value is obtained.

Title: Clearing of pipe clogging and cleaning tool
Inventor: MATSUKUMA NOBORU
IPC: B08B9/02
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To dissolve clogging at the time of accidental clogging of the pipe and to remove soil in the pipe to clean up. SOLUTION: A method in which a hose, etc., is attached at a part former than (2) of the pipe, an entrance and a main body of the pipe are connected and positive pressure is continuously applied thereto or a method in which the hose, etc., is attached at a part former than (10) of the pipe, the entrance and the main body of the pipe are connected and negative pressure is continuously applied thereto, is taken. In both methods, pressure is slight but the pressure, positive or negative, is continuously applied thereto. When positive pressure is applied, pressure is gradually heightened and white mass of oil causing clogging and a detergent, hair, etc., are gradually pushed out and thereby inside of the pipe is very clean after the clogging is dissolved.  When a tool of cylinder type is used, higher pressure is applied and operation time necessary for pushing out the white mass of the oil and the detergent is shorter but even at the time of finishing the work, soil is often remained on an inner wall of the pipe as smooth flow is thought to be attained again owing to a hole bored at a center of the white mass.
