Inventor: HORII KAZUYUKI
IPC: H01L23/50
Filed: 1988-10-14
Abstract: PURPOSE:To facilitate bonding as well as deburring in such a way that there is no possibility of contact between leads by etching extensively the molding outside of an inner lead part as well as the side face of an inner side of each bar at the faces opposite to the bonding parts of the inner lead part. CONSTITUTION:As to each inner lead in a molding part A including each bonding part out of an inner lead part 4, its sectional form is formed almost in a shape of an inverse-trapezoid and as to the inner lead in a part B that is extending outside from the part A in which molding is carried on as planned along each bar 5, its sectional form is formed in the shape of the inverse- trapezoid. Further, the side face of each dam bar of the inner lead is formed into the shape digged deeply and the outer lead 6 of a part C located outside of a dot-dash-line B is formed in such a manner that its cross section has a limited swelling; besides, it is formed almost in the shape of a quadrangle which shows a symmetry between the upper and lower halves. Such a configuration not only prevents each lead from coming into contact with an adjoining lead but also makes bonding parts of the inner leads wide and facilitates bonding as well as deburring.

Title: Signal measuring analyzer
Inventor: HAYAKAWA TADASHI
IPC: G01R19/00
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To simplify a constitution and to shorten a required time by calculating using an arithmetic program devised for controlling effect of noise. SOLUTION: An arithmetic unit 30 calculates to analyze an input value 80 from a signal input unit 10 to measure and analyze an input signal 60 according to an arithmetic program 100 stored in a program storage memory 40. That is, a measured value of the signal 60 at a sampling timing of this time is Vin, and a measured value analyzed result at a sampling timing of previous time stored in an analyzed result storage memory 50 is V. Then, γV+(1-γ)Vin is calculated by using a constant γ(γ<1), and the result V is updated. If noise component is carried on the signal 60, and calculated according to the program 100 by setting noise component N1 to X, the measured value is added by (1-γ)X.  Here, if a value near '1≈ is taken as the γ value, influence of the noise component can be reduced since a small coefficient is multiplied by the measured value of the component.

Title: Dry developing device
Inventor: OKA KENJIYU
IPC: G03G15/08
Filed: 1985-11-18
Abstract: PURPOSE:To vary the density of a developer staying in an empty room and to vary optionally toner concentration on the peripheral surface of a developing sleeve with simple constitution by varying the capacity of the empty room. CONSTITUTION:When the toner concentration is increased, the rotation of an eccentric cam 41 as shown by an arrow (e) causes a movable partition plate 43 to swing right by its own elasticity to increase the capacity of the empty room 15. In this state, the concentration in the empty room 15 decreases to form a new space, but magnetic toner is supplied from a toner storage tank 21, so magnetic toner increases corresponding to the newly formed space, so that the toner concentration of a magnetic developer increases eventually. When the toner concentration is lowered, the rotation of the eccentric cam 41 shown by an arrow (f) causes the movable partition plate 43 to swing to left to decrease the capacity of the empty room 15. Then, the empty room 15 decreases in capacity and increases in concentration, so the toner supply from the toner storage stank 21 is inhibited and the toner is consumed gradually, so that the toner concentration of the magnetic developer decreases eventually.

Title: Air purifier
Inventor: YAGI KENJI
IPC: B01D46/42
Filed: 1994-09-30
Abstract: PURPOSE: To provide an air purifier by which the exchange timing of a dust collecting filter is correctly judged. CONSTITUTION: The number of revolution of a motor 6 for a fan just after a dust collecting filter is exchanged and that of the motor when it is normally operated are detected by a number of revolution detector 7. Further, based on power voltage information from a power voltage detecting part 14 and temperature information from a temperature detecting sensor 12, the the number of revolution detected each are corrected. The corrected number of revolution just after the exchange and the number of revolution at frequency other than that obtained according to information of frequency from a frequency detecting part are stored as reference revolutions. A controller 8 compares the reference revolutions with the revolution on operation, and when the difference is not less than a prescribed value, it judges that the dust collecting filter reachs the exchange time limit.  Further, it outputs a signal to an alarm control part 18 to inform an alarm means of the fact that the dust collecting filter reachs the exchange time limit.

IPC: H04B10/2507
Filed: 1992-09-29
Abstract: PURPOSE:To attain excellent optical communication by connecting directly a dispersion compensation fiber compensating dispersion of a wavelength of an optical fiber in series with the optical fiber at plural positions of a transmission line. CONSTITUTION:An optical fiber 101 is used as a transmission line medium between a transmitter 220 and a receiver 230, and plural (in this case, two) dispersion compensation fibers of the same length are used to compensate the wavelength dispersion. That is, dispersion compensation fibers 110a, 110b are connected in series with plural positions (both ends of an optical fiber 101) of the transmission line. Furthermore, the sum of the length of the dispersion compensation fiber 110 is selected to be the length by which a desired dispersion compensation quantity is obtained. A backward scattered light in a Rayleigh scattered light is attenuated by the optical fiber 101. Since the dispersion compensation fibers 110a, 110b are parted so that the backward scattered light is sufficiently attenuated, multiple reflection is reduced, relative intensity noise is suppressed and an excellent distortion characteristic is improved.
