Title: Fuel control device for engine
Inventor: NAKAGI KAZUYOSHI
IPC: F02D41/12
Filed: 1992-11-17
Abstract: PURPOSE:To avoid excessive fuel injection during a delay period to prevent malfunction such as worsening fuel consumption performance in this period, by releasing regulation for minimum injection quantity to a fuel injecting means during the delay period for fuel cutting in a translation time to a deceleration condition. CONSTITUTION:In a control unit 20, the minimum injection quantity for allowing injection is set for preventing the unstableness of injection quantity because the injection quantity from a fuel injection valve 10 is reduced. However the regulation for the minimum injection quantity of a fuel injection valve 10 is released by confirmation when an engine rotational frequency is equal to a given rotational frequency or more and a throttle valve is fully closed by signals from a rotational frequency sensor 22 and an idle switch 21, in the control unit 20 at the time of translation to a deceleration condition; in the case where fuel supply is not to be immediately stopped but to be delayed for a given period, even a running condition is translated to a condition where a running condition is to be fuel-cut. Consequently, it is avoided that fuel is injected much quantity than needs in this delay period.

Title: Double-walled hollow fiber membrane made of polysulfone
Inventor: KATSUMATA TOSHIYUKI
IPC: D01F6/76
Filed: 1992-11-18
Abstract: PURPOSE:To provide a hollow fiber membrane having a cross section having double-walled ring structure consisting of an inner ring and an outer ring, wherein a part of the outer wall surface of the inner ring is peeled off from the inner wall surface of the outer ring, enabling the increase of the membrane area of a module, capable of holding enzyme, etc., in an intermediate layer and useful as a bio-reactor, etc. CONSTITUTION:A polysulfone is dissolved in an organic solvent for the polymer (e.g. dimethylformamide) to prepare a spinning dope. The spinning dope is used as a main agent and extruded together with a core liquid (e.g. ethanol) through a double-walled ring nozzle provided with a ring-shaped nozzle for spinning dope having an inner diameter of 0.3 mm and an outer diameter of 0.5mm and a circular nozzle for the core liquid having a diameter of 0.12mm. The extrusion rate of the main spinning dope is increased and that of the core liquid is decreased in the above process to increase the film thickness. After passing the extruded fiber through a prescribed space distance, the fiber is introduced into an aqueous coagulation bath having increased bath temperature to increase the diffusion coefficient. The gelatinized fiber is taken up to obtain the objective hollow fiber membrane having a double-walled cross section wherein at least a part of the outer wall surface of the inner ring is peeled off from the inner wall surface of the outer ring and utilizable as bio-reactor, etc.

Title: Moving image encoding device
Inventor: TANAKA AKIYOSHI
IPC: H04N19/625
Filed: 1990-11-28
Abstract: PURPOSE:To decrease the quantity of the codes to be generated over the entire part of a screen and to lessen the deterioration in image quality by quantizing a DC/AC conversion coefft. at the step width larger than a still block for a moving block and increasing the appearance frequency of the value 0 of the DC/AC conversion coefft. after the quantization. CONSTITUTION:The conversion processing with a 1st converter 131 and 2nd converter 132 for the quantization step width is simultaneously executed and the selected 133 signal is outputted as the quantization step width (h) to a quantizing section 7. A selector 133 makes selection operation by a motion compensation control signal which is the output of a motion detecting section 3. Namely, the output of the 1st converter 131 is selected when this control signal is effective for motion compensation and the output of the 2nd converter 132 is selected when this signal is ineffective. Consequently, the conversion output of the 1st quantization step is selected if this signal is effective, hence if the encoding block is the moving block. The value larger than the input quantization step width (g) is thus attained and the quantization is executed at this value. Then, the resolution is lower than in the case of quantization at the step width (g) but the generation frequency of the value 0 after the quantization increases and the quantity of the codes to be generated over the entire part is decreased.
