摘要:
An allocation determining unit determines a bandwidth allocation for each of a plurality of subscriber devices in each data-collection cycle. A history managing unit takes a history of a request increment from a bandwidth request amount acquired from more than one time of data collections and an allocation amount allocated by the allocation determining unit for the bandwidth request amount, and presents a bandwidth request amount for the allocation determination to the allocation determining unit by dividing the bandwidth request amount into a plurality of request increments indicated by the history.

An external additive for electrostatically charged latent image developing toner is provied. The additive includes spherical hydrophobic fine silica particles having primary particles having a particle diameter of from 0.01 to 5 &mgr;m, which fine silica particles fulfill the following conditions (i) and (ii): (i) when an organic compound which is liquid at room temperature and has a dielectric constant of from 1 to 40 F/m and fine silica particles are mixed in a weight ratio of 5:1 and shaken, the fine silica particles disperse uniformly in the organic compound; and (ii) the quantity of primary particles remaining as primary particles when methanol is evaporated under heating by means of an evaporator from a dispersion prepared by dispersing the fine silica particles in methanol and thereafter the particles are held at a temperature of 100° C. for 2 hours, represents at least 20% of the quantity of primary particles originally present. The external additive does not react or has no interaction with an organic photoreceptor and therefore change in quality does not occur or the photoreceptor is not scraped. Furthermore, it has a good flowability and therefore adhesion of a toner to the photoreceptor does not occur.

A door lock actuator device comprises a casing having a common mount for securing the casing to either one of right-handed door and left-handed door of an automotive vehicle. A cover element closes a side opening of the casing, and a motor is accommodated within the casing. A motion conversion means has input shaft connected to the motor, and serves to convert a rotary output motion of the motor into a rocking motion. The output shaft of the device has opposite end regions extending through, and protruding outwardly from the casing and the cover element, respectively, and a swing arm is connected to either one of the end regions of the output shaft. Standardized components are used to realize actuator device for right-handed doors and left-handed doors, to lower the manufacturing cost of the device and simplify the parts stock control.
摘要:
A control cable having an inner cable, a conduit for slidably guiding the inner cable, a tubular liner in the conduit and an interposition. The conduit has an outer spring coated with a synthetic resin. The outer spring is made by spirally winding a steel wire around the liner with remaining a clearance between an inner surface of the outer spring and an outer surface of the liner. The interposition is set in the clearance in order to keep a suitable clearance and to provide a suitable resistance for a relative motion between the liner and the outer spring so that thermal expansion and contraction of the liner is not hindered and the liner cannot easily slip out of the outer spring.

The silicone-based defoaming composition of the invention comprises (a) a polyoxyalkylene group-substituted organopolysiloxane, (b) a dimethyl silicone fluid and (c) a finely divided silica powder. Different from conventional similar compositions, the polyoxyalkylene groups in the component (a) are bonded to the silicon atoms only in the monofunctional siloxy groups and the component (a) necessarily has trifunctional siloxane units. By virtue of this unique formulation, the inventive defoaming composition added to a foaming liquid is very stable against flocculation even at a high temperature and even in the presence of an inorganic salt in a high concentration in the foaming liquid, e.g., dyeing bath.

摘要:
A high frequency narrow-band pass multi-mode filter in constructed in such manner that SAW of SSBW resonators are closely disposed to each other on a single piezo-electric substrate to generate different vibration modes of different resonance frequencies, conditions that the resonators are acoustically coupled to each other to cause these vibration modes, are experimentally found, and the above conditions are satisfied by the filter.In order to reduce the ohmic loss of a very narrow common bus bar, the number of strip pairs of electrode in both interdigital transducers (hereinafter referred to as IDT) is minimized and instead reflectors are provided on the both sides of said TDTs to compensate for the reduction of its Q value. A part of the bus bar for the IDT electrodes is formed integral with some or all of gratings of the reflectors, whereby the connecting positions of the grating electrodes with respect to lead terminals can be positioned with a high freedom.
