Title: Toner for developing electrostatic charge image
Inventor: KUMAGAI YUGO
IPC: G03G9/087
Filed: 1988-02-08
Abstract: PURPOSE:To provide a toner having excellent of set resistance without impairing flowability and fixability by incorporating a copolymer mixture which varies in the compounding ratio of monomers in a 5-40wt.% range between the respective copolymers and has 2.0-3.0 deg. of dispersion as a binder resin into the toner. CONSTITUTION:This toner contains at least >=2 kinds of the copolymers respectively having 1.5X10<4>-5X10<4>, more preferably 2X10<4>-4X10<4> number average mol.wt. and 3X10<4>-14X10<4>, more preferably 5X10<4>-10X10<4> weight average mol.wt. and have 2.0-3.0 deg. of dispersion. The copolymers incorporated into the copolymer mixture are respectively required to contain at least one common monomer as the constituting component and to have the compounding ratios of the monomers respectively varying in the 5-40wt.% range between the copolymers. The region where both the fixability and the offset resistance are good is thereby widened and the flowability of the toner is improved.

Title: Room temperature control mothod of hot blast heater
Inventor: UEDA HIROSHI
IPC: G05D23/19
Filed: 1978-03-09
Abstract: PURPOSE: To constantly maintain the room temperature at the set value of the room thermostat by changing the operation condition automatically following even the sudden change of the room temperature.  
     CONSTITUTION: When the heating load suddenly increases and the room temperature goes down below t1, that is, the output terminal RT1 goes down to L level, PNP transistor Q1 turns on to flow electricity to the base of NPN transistor Q2 through the condenser C4 and the resistance R24 to turn on Q2 and release self- retention of SCR. That is, the memory that the temperature of the room which is heated reached t4 is eliminated. Then, when the room temperature goes down, after it rises above t4, and stays above t2, that is, when B is L and RT2 is H, the output from or-gate Q5 becomes L, NPN transistor Q6 is turned off, and the relay RT1 is not continued and the device is combustion-off-operated.

Title: Transmission signal discriminating device
Inventor: HOSODA KENICHIRO
IPC: G10L25/84
Filed: 1987-02-09
Abstract: PURPOSE:To simplify a discrimination processing while keeping usual discrimination sensitivity and discrimination factor, by forming a prediction signal from an input signal by providing a fixed prediction circuit having one or two or more kinds of fixed predictors, finding a correlation coefficient between the input signal and the frequency characteristic of the fixed predictor, and discriminating and deciding the kind of the input signal based on a found value. CONSTITUTION:The prediction signals S'1(k) and S'2(k) are supplied to a correlation coefficient generation circuit 103 by outputting them from the predictors 106 and 107 respectively, and gain control coefficients g1(k) and g2(k) that are the correlation coefficients corresponding to respective prediction signal by applying a signal processing between the input signal s(k) at the circuit 3. The adder 114 of a discrimination and deciding circuit 104 calculates the differential signal d'(k) of the above gain control coefficient. A comparator 115 compares the differential signal with a prescribed threshold value (a), and outputs a signal d(k). An integrator 117 outputs an integration output d'(k) by integrating the signal d(k) by a desired time. In such a way, the fluctuation of the signal d(k) due to the fluctuation of the power of the input signal can be eliminated. The integrated output d(k) is compared with a threshold value (b) at a comparator 118, then, a discriminated and decided result can be obtained.

Title: Heat exchanger
Inventor: KUMAKURA KAZUHIRO
IPC: F28F1/32
Filed: 1991-01-30
Abstract: PURPOSE:To enhance heat transfer rate of a heat exchanger by forming a slit on a plate continuous fin at a right angle to the direction of a fluid flowing between the fins in a plate continuous fin-equipped heat exchanger. CONSTITUTION:Fins 2 are formed in the shape of a rectangular plate where a side opposed to an air current direction A is shorter. Penetration hole slits 5 are formed on the plane at a specified span. The fins 5 are formed in linear shape and at a right angle to the air current direction A, crossing the fins 2. As a result, a temperature boundary layer formed along the surface of the fins 2 during heat exchanger operation is interrupted at the slits 5, thereby thinning the boundary layer. In the portions from X to Z divided by the slits 5, fluid pipelines 3 are positioned at the upper and down stream sides of the air current A and laid out in two zigzag rows. This construction makes it possible to increase the heat transfer rate greatly since the heat exchange takes place at a high temperature gradient.

Filed: 1982-02-23
Abstract: PURPOSE:To detect internal cracks from the local increase in elastic waves by mounting a sensor which converts oscillations to electrical signals to one of two dies disposed in series, and detecting the elastic waves generated in the metallic wire. CONSTITUTION:A metallic wire 1 passes between rolls 2 for preventing oscillations and is reduced to a metallic wire 5 by means of the fore die 6' and post die 6 of a double die device 3. This metallic wire passes through rolls 4 for preventing oscillations in the outlet and is taken by capstans or into a kettle, whereby the metallic wire is subjected one pass of reduction in area. When cracks are generated in the metallic wire in this stage, the elastic waves of the wire 1 are detected with a sensor 7, which converts the waves to electric energy. The electric energy is amplified with an amplifier 8, is fed to a rate counter 10 via a discriminator 9, and is recorded in a recorder 11. The generation of the internal cracks is thus detected from the local rise in the rate count appearing in the recorder 11.
