Title: Keying control method for automatic piano
Inventor: MORI HAJIME
IPC: G10F1/02
Filed: 1992-05-22
Abstract: PURPOSE:To stably strike the strings of the automatic piano from a weak sound to a strong sound. CONSTITUTION:A keyboard is driven through the operation of an actuator operating under the command of a control circuit at a constant initial speed as shown by a straight line O-E and the control circuit controls the actuator so that the speed is made twice as fast as the initial speed as shown by E-F from a point of time t1 (point E) when the deflection of an elastic system is restored. The point T1 of time is a half cycle of the natural oscillation frequency of the elastic system. The depressing speed of the keyboard at the point t1 of time is equal to the speed of a hammer, which is put in equal-speed motion without speed reduction to nearby the strings to reach the strings at a point F. The speed of the hammer can make variation in driving speed required to vary sound volume even in the weakest sound range larger than that of a conventional example and the strings can be struck in a time almost a half as long as that of a method which uses constant acceleration.

Title: Pressure measuring instrument
Inventor: SAKAMOTO TSUTOMU
IPC: G01L9/12
Filed: 1986-07-04
Abstract: PURPOSE:To execute a pressure measurement stably and with high accuracy by constituting the titled instrument so that pressure can be measured by comparing a capacity to be measured, with a reference capacity whose capacity value is roughly constant. CONSTITUTION:As for this capacitor, the reference capacity CR scarcely causes the change in the lapse of time, and the capacity is scarcely varied even by a variation of a temperature. Also, a capacity CX to be measured and a reference capacity CR constitute integration circuits I1, I2 of operational amplifiers 20, 21 and resistances R11, R21, respectively. Outputs of the circuits I1, I2 are inputted to window comparators WC1, WC2, outputted as a value corresponding to the time length, and subsequently, its outputs are inputted to frequency counters FC1, FC2, and a frequency corresponding to the time length is outputted as a count signal. Next, in an arithmetic circuit 30, from a capacity value of the capacity CR and the respective count signal values, a capacity value of the capacity CX is calculated, and also, from this capacity value, pressure at that time is calculated. Accordingly, even if a value of a circuit element of the resistance, etc. causes the change in the lapse of time or a temperature variation, it is offset since both the capacity to be measured and the reference capacity are varied simultaneously, and no measurement error is generated.

Title: Apparatus for restoring electrode short-circuit of metal particle detection sensor and method therefor
Inventor: KODA NORIAKI
IPC: G01V3/02
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To continuously measure the particle size distribution of metal particles by providing a means outputting a short-circuit signal when electrodes are short-circuited and restoring a short-circuit state when the short-circuit signal is continued for a predetermined time or more. SOLUTION: A short-circuit detection means 10 outputs a short-circuit signal to an electrode storing means 30 when a short-circuit state is generated between electrodes 2a, 2b. The restoring means 30 outputs an operation command to a switch 59 when the short-circuit signal continuous for a predetermined time or more and a parallel circuit of resistors 35, 5 is formed. The resistor 5 is set so as to have a resistance value larger than the resistance value Ro between the electrodes obtained when metal particles are attracted and the resistor 35 is set so that the resistance value thereof is lower than that of the resistor 5 but larger than Ro.  In such a case that metal particles attracted between the electrodes 2a, 2b are not scattered, when the short-circuit signal from the short-circuit detection means 10 is continuously outputted for a predetermined time or more, the electrode restoring means 30 fonts a parallel circuit of the resistors 35, 5. As a result, a large current of a predetermined value or more flows to the resistor 35 to scatter metal particles. By this constitution, a short-circuit state is restored and the particle size distribution of metal particles can be continuously measured.

Title: Exhaust tube device
Inventor: ISHIRO BUNJI
IPC: F23J15/00
Filed: 1987-06-23
Abstract: PURPOSE:To prevent the condensation of water vapor, contained in exhaust gas, in an outdoor exhaust tube, by a method wherein a condenser, condensing the water vapor contained in the exhaust gas, is provided in the exhaust tube while the discharging port of air, whose temperature is raised by heat exchange through the condenser, is opened at the downstream side of a heat exchanger in the exhaust tube. CONSTITUTION:When fuel is burnt in a burner 1, a large amount of water vapor is discharged by combustion together with exhaust gas; however, combustion gas is cooled suddenly in a condenser 3. Water vapor, contained in the combustion gas, is condensed and removed; therefore, moisture contained in exhaust gas is reduced suddenly. Air, whose temperature is risen by heat exchange between the exhaust gas in the condenser 3, is returned into an exhaust tube 2 again through a discharging port 4. Accordingly, heat loss will never be generated in the exhaust tube 2 and heat is discharged when the water vapor is condensed; therefore, the temperature of the exhaust gas is not reduced substantially by flowing atmosphere into an exhaust tube 2, the content of moisture is reduced remarkably and poor exhaust due to the deterioration of draft will never be generated.

Title: Resonance tunnel diode
Inventor: BABA TOSHIO
IPC: H01L29/88
Filed: 1988-06-23
Abstract: PURPOSE:To obtain the high ratio of peak to valley by bringing conduction bands at inclined barriers and an inclined well to a level and equaling the energy at bottoms of the conduction bands to energies of inclined barrier layers and inclined well layer when resonance tunnel is produced in the whole structure by applying voltage across both ends of cathode and anode. CONSTITUTION:This device has a laminated structure consisting of inclined barrier layers 6 and 8 as well as an inclined well layer 7 between a cathode 1 and an anode 2 consisting of n-type semiconductors in such a way that the inclined barrier layers have the thicknesses which allow electrons to tunnel into the layers and energy at bottoms of conduction bands becomes high as it approaches to the anode side and further, the inclined well layer has the thickness which is less than a de Broglie wavelength and energy at the base of the conduction band becomes high as it approaches to the anode side. Then, the conduction bands at the inclined barrier layers 6 and 8 as well as the inclined well layer 7 become flat and energy at the bottoms of the conduction bands coincides with respective amounts of energy of the inclined barrier layers 6 and 8 as well as the inclined well layer 7 when the whole laminate structure generates resonance tunnel by applying voltage across both ends of the cathode 1 and anode 2. As levels of energy at barriers and a well thus become equal to each other, the transmissivity approaches 0.1 and then, the high ratio of peak to valley is obtained.

Title: Developing device
Inventor: SATO HISAO
IPC: G03G15/08
Filed: 1988-06-23
Abstract: PURPOSE:To automatically set desired crest quantity with a simple operation by setting the crest quantity of developer carried around the periphery of a developer carrier based on balance between the dead load of a crest control plate and the reaction of a developer layer, which is generated by the pressing with the crest control plate when the developer carrier is rotated. CONSTITUTION:The crest control plate 42 is placed on a fixing stand 4B. A set screw 43 is released through an oblong hole so that the crest control plate 42 can slide down by its dead load. When a developing sleeve 41 starts adsorbing and carrying of the developer, the crest control plate 42 slides down along the fixing stand 4B, goes a little bit away from the periphery of the developing sleeve 41 and stops in a position where the reaction and the dead load are balanced. Therefore, the dead load of the crest control plate 42 is selected so as to obtain the desired crest quantity. Thus, the crest quantity of the developer can be uniformly set with high accuracy by the quite simple operation.

Filed: 1994-06-15
Abstract: PURPOSE: To lessen the loss by combustion of floating coke by adding oxygen by a hard stream into a settling tank and in addition, blowing oxygen by a soft stream in order to partly oxidizing the floating coke.  
     CONSTITUTION: The ores or pre-reduced metal carriers enter the independent settling tank 20 through a juncture 16 from a smelting reduction reactor 10 in the form of an emulsion consisting of slag, liquid metal and floating coke particles. The ores or metallic carriers are converted to low carbon content pig iron by the hard blown stream of the oxygen from a pipe 36 in this tank. In this method, a pipe 38 having an annular spacing 39 is projected into the upper tank 22 of the settling tank 20 and the softly blowing of oxygen is executed from the spacing 39. As a result, part of the floating coke is oxidized and the volume of gas increases. The gas flows through the juncture 16 into the smelting reduction reactor 10. The coke particles floating on the emulsion, therefore, flow back and the purposes are achieved.

Filed: 1984-07-26
Abstract: PURPOSE:To prevent the generation of a weld defect by detecting the gap generated between both works in accordance with the change in the arc current during arc scanning for detecting the gap. CONSTITUTION:The arc scanning for detecting the gap is executed by moving a torch 12 in parallel with the face 200 adjacent to the weld line of one work 18b and scanning the arc in the prescribed section mn between the weld line AB and one work 18b. When the mn section is subjected to the arc scanning for detecting the gap, the current smaller than the arc current IC generated in the stage of scanning the face 200 of the work 18b is generated in the stage of scanning the region of a gap 100 and the large current change arises at the point pq where the arc scanning changes over between the face 200 and the gap 100. The gap 100 existing between the works 18a, 18b is thus surely detected and the size thereof is detected if necessary.
