Title: Refuse discharge control method
Inventor: TOMA ICHIRO
IPC: B65G53/48
Filed: 1994-05-19
Abstract: PURPOSE:To shorten an operation time by efficiently transporting refuse without influencing on the differences of a transport distance or refuse quality. CONSTITUTION:The rotation frequency of a rotation drum is set into plural stages in accordance with the kind of refuse accumulated in a control device 5 at every each refuse accumulation discharge device to control the rotation frequency of the rotation drum at every refuse accumulation discharge device independent from a collecting center 1 to restrain an influence due to differences of a transport distance or refuse quality. When the refuse is discharged from the refuse accumulation discharge device, the rotation frequency of the rotation drum is restrained into small directly after starting discharge to restrain enlargement of transport pressure loss. The rotation frequency of the rotation drum is changed by stages at every elapse of a predetermined time from starting discharge to adjust the discharge quantity of the refuse to be discharged to restrain the change of the transport pressure loss of the refuse in a transport pipe into a fixed range.

Title: Sale time point information management terminal provided with life detection mechanism in printer
Inventor: YAMANE RIKA
IPC: B41J29/20
Filed: 1991-05-31
Abstract: PURPOSE:To prevent using an ink ribbon for more than its life. CONSTITUTION:A receipt/journal printer 2 is mounted on a POS terminal 1. When a program part 3 outputs a printing instruction to the receipt/journal printer 2, the program part 3 executes an internal operation and writes the number of printed characters into a nonvolatile memory 4. A life recognition part 5 reads the value of the nonvolatile memory 4, compares the value of the nonvolatile memory 4 with a value which is stored in ROM 5a and which is previously stored, decides how close the value of the nonvolatile memory 4 is to the number of life characters, displays an ink ribbon exchange message to a display part 6 as the value approaches to an exchanging time and stops the printing operation of the receipt/journal printer 2 even if the printer part 3 issues a printing instruction when the value becomes over the number of the life character and gets to a limit value.

Title: Frequency synthesizer
Inventor: SAUL PETER HENRY
IPC: G06F1/03
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a frequency synthesizer that is mass-produced even at a low cost and especially suitable for a local oscillator and other similar applications. SOLUTION: A frequency synthesizer has a direct digital frequency synthesizer(DDFS) 1, and D/A converters 12, 13 and a balanced mixer 2 of the DDFS 1 give sine wave signals of an in-phase and a quadrature phase to an input signal with a frequency for the time being. The balance mixer 2 having a carrier frequency gives an output signal from the DDFS 1 twice and a spurious signal whose level is reduced to the carrier signal. The signal having a desired frequency is generated by controlling the DDFS 1 so as to produce a sine wave output signal at a half of the desired frequency. The spurious signal whose level is reduced by the configuration is adapted to, e.g. a local oscillator application, to produce a more improved signal.

Abstract: PURPOSE:To increase a proportion of combustion in a fluidized bed and to enable to perform complete combustion and stable operation, by a method wherein air nozzles are formed in the inner side wall of a fluidized bed below a waste charging port so that they face downward. CONSTITUTION:The inner side wall of a fluidized bed 3 below a waste charging port 4 is installed so that it extends upward at an angle of 5-15 deg. with a perpendicular direction. Namely, an angle theta of an inner side wall 8 of the fluidized bed with a perpendicular surface is set to 5-15 deg., air nozzles 9, for blowing in a part of the air for combustion, are formed in the inner wall 8 of the fluidized bed below the waste charging port 4 so that they point downward, and this causes a part of the air for combustion to be concentratedly injected obliquely downward to the vicinity of the inner wall of the fluidized bed below the waste charging port 4.

Title: Optical recording method
Inventor: YOSHIMURA MOTOMU
IPC: B41M5/26
Filed: 1987-05-27
Abstract: PURPOSE:To multiplexedly record information in an optical recording medium in the level of wavelength by using a phenomenon that the light absorption spectrum characteristics of the optical recording medium are changed before and after light absorption to change light intensity per unit area without changing the wavelength of a laser beam and to radiate the laser beam. CONSTITUTION:When light intensity per unit area is changed without changing the wavelength of a laser beam 2 by using the phenomenon that the light absorption spectrum characteristics of the optical recording medium are changed before and after light absorption and the laser beam 2 is projected to the optical recording medium 3, information can be multiplexedly recorded in the medium 3 in the level of wavelength. Namely, electromagnetic intensity based on the action of the laser beam 2 of its own as an electromagnetic wave is changed by changing light intensity per unit area of the laser beam 2 for optically recording information, so that even if the oscillation wavelength of the laser beam 2 of its own is fixed, a wavelength position generating a hall burning reaction e.g., can be controlled by the field intensity of the laser beam 2. Consequently, multiplex recording in the level of wavelength can be attained.

Title: Production of aqueous solution of calcium dicyanamide
Inventor: NAKAMURA AKIRA
IPC: C01C3/18
Filed: 1986-06-03
Abstract: PURPOSE:To obtain an aqueous solution of calcium dicyanamide having stable purity, by adding calcium hypochlorite to a reaction product of calcium cyanamide and cyanogen chloride and heat-treating the mixture. CONSTITUTION:An aqueous solution of crude calcium dicyanamide is produced by reacting calcium cyanamide with cyanogen chloride in an aqueous solvent. Since the obtained crude solution is usually alkaline, it is adjusted to 4-8 pH with an acidic substance. The pH-adjusted solution is added with calcium hypochlorite and heat-treated to obtain the objective aqueous solution. The acidic substance is preferably hydrochloric acid. The pH of the aqueous solution should be kept within 4-8 to prevent the decomposition of calcium dicyanamide. The heat-treatment is carried out at 50-90 deg.C usually for 1-8hr. Too long heat-treatment is undesirable because it causes decomposition of calcium dicyanamide.

Filed: 1991-05-01
Abstract: PURPOSE: To mold a fuel tank not generating the leakage of fuel and excellent in heat insulating properties by injecting a resin into a mold to impregnate a fiber material with the resin and prescribing the interior of a tank by a support to cure the resin. CONSTITUTION: The wall surface 16 of a fuel tank is prescribed by an inner liner 12 and a fiber material impregnated with a resin. The fiber material impregnated with the resin prescribes the size of the tank wall surface 16 and the liner 12 covers the inner surface of the resin impregnated fiber material. The pipeline 18 communicating with the interior 20 of the tank is formed so as to be extended and a metal filler 22 can be attached to the leading end of the pipeline 18. Since the pipeline 18 is integrated with the one-piece structure of the tank 10, a bonding line is not present on the tank wall surface 16 and the pipeline 18 is continuously extended to be integrally formed to the tank wall surface 16. Therefore, the bonding line required when an injection neck part is connected to the tank wall surface 16 is avoided and the structural integrality of the tank 10 is enhanced.
