Title: Production of zinc ferrite pigment
Inventor: KAWAKAMI TORU
IPC: C09C1/22
Filed: 1986-06-25
Abstract: PURPOSE:To produce zinc ferrite pigment having improved heat resistance, dispersibility and yellow clarity, by precipitating and depositing zinc hydroxide from a water-soluble zinc compound on yellow iron oxide pigment in an aqueous medium, calcining the pigment at high temperature and washing with water. CONSTITUTION:Yellow iron oxide pigment is dispersed into water and an aqueous solution of a water-soluble zinc compound such as zinc chloride, etc., and an aqueous solution of an alkalizing agent such as NaOH, etc., are simultaneously added to the dispersion. The mixed solution is adjusted to pH about 7.0-9.0, stirred and zinc hydroxide is precipitated and deposited on the surface of the pigment at about 0-40 deg.C. The prepared mixture is washed with water, dried, calcinied at about 900-1,050 deg.C and gradually cooled in a temperature range of about 300-600 deg.C for >=about 30min. Then the cooled calcined substance is washed with water into <=about 0.2wt% inorganic salt content in the formed pigment. By this method zinc ferrite pigment having improved dispersibility, heat resistance, strong yellow and high clarity is obtained.

Title: Water feeding method to waste heat boiler of fluidized bed type waste in cinerator
Inventor: AKIYAMA HAJIME
IPC: F22D5/30
Filed: 1995-06-14
Abstract: PURPOSE: To provide a water feeding method to a waste heat boiler capable of reducing small in variations of the amount of steam produced following variations in the amount of combustion even if combustion variations are produced. CONSTITUTION: There are sent, to a calculation control mechanism 40, a waste supply amount measured by a waste supply amount measurement device 30, a steam production amount measured by a steam flow rate meter 25, and a water level signal in a boiler drum 21 measured by a level meter 24. In the calculation control mechanism 40, calculation is performed based upon these signals. A signal of the feed water amount determined by the calculation is sent to a feed water flow rate adjustment meter 26 for adjusting the amount of feed water. Upon the above described water feeding, when the amount of supply of waste falls within a predetermined range, flow rate control is effected based upon the amount of the produced steam and the water level measured value in the boiler drum, while when the amount of supply of waste is out of the predetermined range, flow rate control in response to the amount of supply of waste is effected. Hereby, quality of the amount of the produced steam is improved for effective versatile utilization of produced steam.

Title: Power unit, power unit for driving refrigerating cycle provided therewith, and air conditioner using the same for the driving refrigerating cycle
Inventor: HIRUMA ATSUYUKI
IPC: H02M7/217
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To improve the power factor of a power unit under a low supply capability by setting parallel resonance circuits to a short-circuiting state and setting a switching element to a turned-on state for a prescribed period of time, only after an AC voltage has been detected at its zero-crossing point, and then, switching the output of the power unit to the output of a converter by turning on/off the power unit near the resonance frequency. SOLUTION: The output signal of a current detector 24 which detects an input current supplied from an AC power source 1 and that of a zero-crossing point detector 25 for AC voltage are added to an outdoor control section 50. The conducting angle of the waveform of the current is expanded by short-circuiting the AC power source 1 through a reactor 2 for a prescribed period of time, only after the AC voltage passes the zero-crossing point in a high power-factor conducting mode. When a switch 17 and a changeover switch 18 are connected to each other in the state shown in the figure, a buffer capacitor 21 generates a DC voltage by smoothing the AC voltage. When an IGBT 22 is on/off-controlled near a resonance frequency, a DC voltage is impressed upon a resonance circuit composed of a capacitor 19 and an induction heating coil 20B.  Then the IGBT 22 is set to a turned-on state, immediately after the AC voltage passes the zero-crossing point.

Title: Preventive method of floating electron emission from first control electrode of cathode-ray tube and first control electrode
Inventor: SUMI KOICHIRO
IPC: H01J29/48
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent emission of a floating electron, reduce floating capacity between electrodes, and improve an image quality by covering a part where a first control electrode is opposed to a cathode substance covering surface with a substance such as gold which has a high work function and is low in reactivity with a cathode substance. SOLUTION: A part where a plate-like first control electrode G1 of a cathode-ray tube is opposed to a cathode substance covering surface (a) of a cathode K, is covered with a substance such as Au, Ni and Co which has a high work function and is low in reactivity with a cathode substance (a) by a method such as ion sputtering, evaporation and plating. Therefore, even if barium (b) sticks to a surface where the first control electrode G1 is opposed to the cathode and exists as a barium oxide by oxidizing gas in the cathode-ray tube, reaction with a reducing agent contained in a raw material of the G1 is restrained by an inactive metallic coating film, and generation of a floating electron is restrained, and an image quality in a dark image screen can be improved.  An evil influence by discharge of the floating electron generated by the G1 at operating time of the cathode-ray tube can also be restrained.

Abstract: PURPOSE:To facilitate the assembly of a battery by packing a positive pellet into a positive can, the diameter of the lower part of which is smaller than that of the upper part, pouring an electrolyte over a separator placed on the positive pellet, giving a specified vibration to the positive can, and attaching a negative can to the positive can to hermetically seal the battery, and thereby increasing the liquid absorbing speed. CONSTITUTION:A pellet 4 is installed in a positive can 1, the diameter of the lower part of which is smaller than that of the upper part, the pellet 4 is compressed by pressing, and a separator 6 is placed on the pellet 4 compressed. After an electrolyte 7 is poured on the separator 6, the can 1 is placed on a vibrating plate 8 and is given a vibration with an acceleration of 1-3G and a frequency of 50-500Hz. Following that, a negative can containing both a negative electrode and an electrolyte is attached to the can 1, with a gasket interposed between the can 1 and the negative can, to hermetically seal the battery, thus a button-type battery is assembled.  The electrolyte 7 is preferred to be poured on the separator 6. Or else, it is preferable that 40-60% of the electrolyte 7 is poured on the positive electrode 4, and that  the other 60-40% is poured on the separator 6. By the means mentioned above, the  electrolyte 7 is rapidly absorbed by the separator 6 and the positive electrode 4. Consequently, this method, which is applicable for an alkaline or an organic electrolyte battery, facilitates the assembly of a battery and decreases the variation in battery performance.
