Title: Screw compressor
Inventor: DEGAWA TAKU
IPC: F04C29/02
Filed: 1979-04-18
Abstract: PURPOSE: To promote the separation efficiency in a screw compressor by providing a runner using the rotatory power of a rotor and using its centrifugal force to  separate oil from gas with a large difference of specific gravities.  
     CONSTITUTION: The refrigerant gas compressed by the compressing work based on the engaging rotation of both rotors 4 and 5 is mixed with injected oil, and discharged near to a runner 19 in a primary chamber 15 through a discharge port 13. Between mixed currents flowing into both passages 20 and 21 in the runner 19, the one of oil with a larger specific gravity is scattered outward radially from the passage 21 into the primary chamber 15 by the centrifugal force caused by the rotation of the runner 19 as resisting against the current of gas, and dropped to an oil reserving part 15' below to maintain an oil surface. The other of gas with a smaller specific gravity, since the sentrifugal force given by the runner 19 is very small, is issured into a secondary chamber 16 via a radial passage 20 as concentrating to the central part of the runner 19, and discharged into a refrigerant cycle through a discharge port 12.

Title: Moving average filter
Inventor: SUZUKI HIROAKI
IPC: H03H17/06
Filed: 1984-03-12
Abstract: PURPOSE:To output always a correct result by adding a circuit for simple discrimination and correction in calculating a running sum so as to allow the discontinuity generated depending on the property of an input data to be made proper into an actual consecutive quantity. CONSTITUTION:A comparator circuit 8 and a correction circuit are provided additionally to a conventional circuit. The comparator circuit 8 discriminates whether the relation of beta<=thetaIN-IR4<alpha exists between given values alpha and beta. In case of an example of this execution, the values alpha and beta are selected respectively as +180 deg. and -180 deg.. When the result of discrimination is within a prescribed range, the data is fed to an addition register 5 and processed as a conventional method. When the result of discrimination is larger than the alpha, 360 deg. is reduced from the data by the correction circuit 9, and the result is fed to the addition register 5. When the result of discrimination is smaller than the beta, after 360 deg. is added by the correction circuit 9, the result is transmitted to the addition register 5. Thus, the correct output value is obtained. The preceding circuits after the addition register 5 are the same as the conventional method.

IPC: B41J2/385
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a flying recording type image forming apparatus capable of suppressing lowering of an image density that may occur when forming a high density image. SOLUTION: The number of formed dots of each color image is calculated by each of dot counting devices 202K, 202M, 202C, 202Y, respectively and the data of the number of formed dots is transmitted to a CPU 201. In the case where a density of an yellow image is possibly lowered by allowing toner on a toner carrier roller in a particle flying control section to run out as, for example, the number formed dots of the yellow image exceeds a predetermined number, a CPU 201 is instructed to change a content of a control signal for each device or a driving device. By the change, an operational condition that influences a quantity of the toner passed through each of the holes is changed, then it is possible to raise a density of the formed image by increasing the quantity of the toner passed therethrough.

IPC: H03B5/12
Filed: 1995-03-07
Abstract: PURPOSE: To suppress spurious oscillation without giving effect on the oscillating condition at a desired frequency band by inserting a resistor between a transistor(TR) and a varactor diode. CONSTITUTION: A resistor 11 is inserted to a connecting point between a tip open stub 3 and an emitter terminal of a TR 1 in order to obtain a characteristic that a low loss at a desired frequency and a high loss are produced for frequencies other than the desired frequency band to suppress the loop gain other than the desired frequency band. That is, the characteristic impedance of the tip open stub 3 when viewing it from the emitter terminal of the TR 1 is an open impedance in the vicinity of the desired frequency band, and a loss by the resistor 11 connecting in series with the connecting point between the tip open stub 3 having an open impedance and an emitter terminal of the TR 1 is low in the vicinity of the desired frequency band.  Since the loss by the resistor 11 is high for other frequencies than the desired frequency band, the loop gain at other frequencies than the desired frequency band is suppressed without suppressing the loop gain at the desired frequency band.

SOLUTION: This resin compsn. is prepd. by melt mixing a polyolefin with an unsatd. carboxylic acid (deriv.) and mixing the resultant mixture in a molten state with a thermoplastic polyester. The polyolefin is an α-olefin (co)polymer and is pref. selected from among polyethylene, polypropylene, and an EP rubber. The acid is pref. an anhydride such as maleic anhydride. An esp. prepf. example of the polyester is polybutylene terephthalate. A thermoplastic polyester having an intrinsic viscosity of 0.52-1.35dl/g is suitable in terms of mechanical strengths and moldability. If necessary, a thermoplastic polyester, which may be the same as or different from one described above, may be further mixed into the compsn. Thus prepd. compsn. is suitable for a thin-walled molded item and is useful for a molded item having a hinge part, esp. for a wire harness connector.
