Title: Ink jet recorder and its driving method
Inventor: SAKAI MARI
IPC: B41J2/055
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To secure sufficient displacement of a diaphragm by controlling drive voltage low even though an ink jet is arranged in high density by a method wherein after vibrating the diaphragm in small vibration state where an ink drop is not discharged, vibration enough to discharge the ink drop is induced in the diaphragm. SOLUTION: A diaphragm 51 is finely vibrated prior to actual discharge of an ink drop. Therefore, a value of peak voltage for displacing the diaphragm 51 until it comes in contact to a surface of an opposed plate necessary for actual discharge of the ink drop can be decreased. Then, by a method of charging to a voltage value necessary for discharge of ink after forming a small vibration state in the diaphragm 51, it can be vibrated without requiring so large driving voltage irrespective of a small size diaphragm. Further, since a gap may be not narrowed, a sufficient amount of the ink drop can be discharged. Therefore, making high density of an ink jet head can be easily realized.

Title: Method of chemically storing cooling energy
Inventor: KAWASAKI SHIGETAKE
IPC: C09K5/08
Filed: 1986-08-18
Abstract: PURPOSE:To store cooling energy with reduced refrigerator load, by dispersing a liq. halogenated hydrocarbon refrigerant which reacts with water to deposit hydrate crystals in an aq. alcohol soln. and then cooling so as to deposit hydrate crystals of the refrigerant in which crystals cooling energy is stored. CONSTITUTION:A liq. halogenated hydrocarbon refrigerant which reacts with water to deposit hydrate crystals (e.g., flon 11 or flon 12) is dispersed under agitation in an aq. alcohol soln., e.g., aq. ethanol soln. or aq. n-propanol soln. The soln. is cooled to deposit hydrate crystals of the halogenated hydrocarbon refrigerant in which crystals cooling energy is stored. If necessary, the hydrate refrigerant is decomposed, and air or a heat medium is cooled by the endothermic reaction caused thereby. This system can advantageously be used in air-conditioning of buildings, the refrigeration system for refrigerated warehouses, etc.

Title: Radiation type computer-aided tomograph
Inventor: YAMAMOTO SEIICHI
IPC: G01T1/161
Filed: 1981-11-30
Abstract: PURPOSE:To enable immediate determination of a radioactive isotope (RI) distribution in a body with an absorptive correction of radiation in the body by detecting radiation emitted from the RI accumulated in an object to be inspected (body of a patient) outside the body to obtain a distribution image of radiation absorption coefficient on the same condition as the RI distribution image simultaneously. CONSTITUTION:Parallel gamma ray beams (as indicated in the dotted line) are irradiated on an object 7 from the side of a camera 1 to be inspected and those transmitting the object 7 enter a camera 8. The gamma rays (as indicated by the solid line) emitted from the RI accumulated in a specific organ of the object 7 enter the camera 8 and a camera 1 facing it. The RI dosed to the object 7 and the RI buried in a collimator 2 are different in the type of energy of gamma rays to be emitted therefrom. In the camera 8, discrimination of energy of incident gamma rays enables detection of only the gamma rays transmitting the object 7 from the side of the camera 1 thereby affording a data concerning the intensity of the radiation transmitted.

Filed: 1986-08-20
Abstract: PURPOSE:To correct the measured value of a hemolyzed blood specimen even with respect to an item to be examined of which the concn. in an erythrocyte is higher than that in serum or plasma, by preliminarily calculating the relation between a grade of hemolysis and the value of an error given to the item to be examined from the values obtained from a large number of actual specimens obtained by destructing the erythrocyte separated from plasma by measurement. CONSTITUTION:At first, the relation between a grade of hemolysis and the value of an error given to an item to be examined brought about by hemolysis is preliminarily calculated with respect to the item to be examined of which the concn. in an erythrocyte is higher than that in serum or plasma. Next, the analytical operation of the item to be examined is carried out with respect to a blood specimen to obtain a measured value before correction. Further, the grade of the hemolysis of the blood specimen is calculated. Then, from the grade of hemolysis of said blood specimen, the measured value before correction is corrected based on the relation previously calculated. Further, the relation between the grade of hemolysis and the error value is set with a gradient and the tolerant width following the same and the value after correction of the measured value before correction is displayed as the value having the tolerant width. The gradient and the tolerant width are calculated for each group classified by a health state, an age and sex.

IPC: H04N5/21
Filed: 1983-10-19
Abstract: PURPOSE:To prevent a malfunction and the deterioration of picture quality which are due to noises by controlling the pass characteristics in response to the level of an inter-frame difference signal of an input picture signal as well as the pass characteristics in response to the magnitude of a signal component corresponding to the horizontal/vertical edge part of a picture. CONSTITUTION:The interlace scan picture signals are supplied to the cascaded field memories 1-1 and 1-2. An inter-frame sum signal (a) and an inter-frame difference signal are produced by an adder 3 and a subtractor 4 respectively. The signal (a) is added 22 with a vertical low band component signal (b) which is delayed by a field via coefficient devices 18-21 and sent to an adder 24 after 1/2 multiplication 23. While the coefficient values of devices 18-21 are controlled via switches SW1 and SW2 in response to the levels of horizontal and vertical edge signals extracted via HPF15 and 16. The output of the subtractor 4 is sent to an inter-frame difference signal processing circuit 17, and switches SW1 and SW2 are switched and controlled in response to the presence or absence of significance. Thus it is possible to transmit successively scan picture signals which are free from deterioration of picture quality.

IPC: H01M4/38
Filed: 1992-07-21
Abstract: PURPOSE:To provide a hydrogen storage electrode, having a long cycle life and improved discharge capacity when used as the negative electrode of an alkaline battery, without causing a complex manufacturing process. CONSTITUTION:A hydrogen storage electrode is manufactured by making the grain diameter of hydrogen storage alloy powder have less 50mum and by pressurizing copper plating alloy powder, to which copper plating having 10-20wt.% of the whole weight is applied, until a porosity of 10-25% is obtained. Consequently manufacture is made by a manufacturing process simpler than that of a sintered hydrogen storage alloy electrode or a non-sintered hydrogen storage electrode using a fluororesin binder. Also discharge capacity and a cycle life more excellent than the same of the non-sintered hydrogen storage electrode, in which the fluororesin binder or much copper powder conductive aids are used. This is estimated that copper, plated on a hydrogen storage alloy powder surface, is rich in ductility, and consequently is sufficiently stuck close by subsequent pressurization, increasing bonding force between hydrogen storage alloy powders and between the hydrogen storage powder and a collector.
