Title: Carburetor with variable venturi section
Inventor: NARASAKA SHIN
IPC: F02M1/02
Filed: 1982-03-25
Abstract: PURPOSE:To improve starting and warm-up, by moving a piston in such a direction as to decrease the cross-sectional area of a Venturi part when a choke valve is not higher than a prescribed degree of opening, to prevent the mixture of air and fuel from becoming too thick at the closure of the choke valve. CONSTITUTION:Normally, intake air flows in a direction A depending on the degree of opening of a throttle valve 3 and a piston 6 is moved depending on the difference between the atmospheric pressure in an air passage 9 and the intake pressure or Venturi negative pressure in an air passage 10. The piston 6 is moved up and fuel injected from a main nozzle 13 is increased as the rotational frequency of an engine rises. When a chock valve 4 is set not higher than a prescribed degree of opening at the low temperature of the engine, a control circuit 22 operates a solenoid valve 21 through a drive circuit 23 depending on the output voltage of a choke valve opening degree sensor 24 to connect the top of an intake air chamber 5 to an atmosphere release port 19 to prevent the excessive rise in the Venturi negative pressure to keep the piston 6 from being moved too much.

Title: Sublimable thermal transfer recording medium
Inventor: MOCHIZUKI HIDEHIRO
IPC: B41M5/40
Filed: 1989-02-28
Abstract: PURPOSE:To obtain a sublimable, thermal transfer recording medium which allows highly uniform image to be visualized by forming a dye supply layer consisting of more than two layers and reducing the dye density of a dye supply layer near a dye transfer contributing layer beyond the level of the dye density of a dye supply layer that is near a substrate. CONSTITUTION:A dye supply layer 4 consists of more than two layers and the dye density of a dye supply layer 4a near a dye transfer contributing layer 5 is lower than that of a dye supply layer 4b near a substrate. The dye density of the dye supply layer 4a which is located at the top is higher than that of the dye transfer contributing layer, and the dye density of the dye supply layer 4b which is located at the bottom is assumed to be 10, against which the dye density of the layer 4a is 9 or less. Then independent layers are formed on a substrate by applying the same amount of material in accordance with each prescription for the dye supply layer and the transfer contributing layer under the design of prescribing a material for the dye supply layer and transfer contributing layer. After this, an image- receiving layer is placed together with these independent layers respectively and a constant sublimation temperature is applied to these layers placed together. In this case, an appropriate density gradient or/and further a diffusition factor is provided between the dye supply layer and dye transfer contributing layer so that the relationship between the sublimable transfer amounts is the dye supply layer > the transfer contributing layer.

Title: Dab receiver
Inventor: OBATA KIJURO
IPC: H04B1/16
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To shorten a seek time of a DAB signal by providing a frequency list storage means that stores a frequency list of receptible DAB signals detected by a DAB detection means in cross reference with a prescribed TII. SOLUTION: When a detection section 80 detects a state of background operation, a control section 60 allows a tuner section 10 to receive an optional DAB signal. In this case, a processing section 20 reads a TII (transmitter identification signal) being received and when the read TII differs from a TII having been read just before, the tuner 10 receives a DAB signal at a lower limit frequency of a DAB frequency band to seek all frequencies from the lower limit to the upper limit of the DAB frequency band. When a reception signal strength is a prescribed threshold level or over and a Null symbol is detected and a phase reference symbol is detected, the reception frequency is registered in a DAB frequency list stored in a memory 70 together with the TII. Then the reception frequency is being increased, the operation above is repeated.  In this case, when both symbols are detected, it is discriminated that the DAB signal is received.

Filed: 1990-02-28
Abstract: PURPOSE:To separate and recover Rh at superior recovery rate by bringing hydrochloric acid solution of Rh containing base metals into contact with a dialkylsulfide-containing organic solvent to extract this Rh in the organic solvent and then adding an eluent to the organic solvent. CONSTITUTION:A bivalent tin halide, such as SnCl2, is added to a hydrochloric acid solution of Rh which contains Fe, Ni, Zn, Sn, etc., other than Rh and in which hydrochloric acid concentration is regulated to 0.5-1.2N by the amount 1.5-2times Rh by mole ratio. Subsequently, an organic solvent, such as paraffinic hydrocarbon, containing di-n-hexylsulfide, such as dialkylsulfide, as extracting agent for Rh is added to the organic solvent and sufficient agitation is exerted so that they are brought into sufficient contact with each other, by which Rh is extracted in the organic solvent. Since Sn is simultaneously extracted at this time, the organic solvent phase is cleaned with 0.5-1N dilute hydrochloric acid to elute Sn, and then, H2S is blown to precipitate Rh in the form of sulfide. By carrying out filtration and high temp. heating, metallic Rh can be separated and recovered from the sulfide of Rh in superior yield.
