Abstract: A developer unit adapted to develop a latent image with toner particles. The unit includes a housing defining a chamber for storing a supply of toner particles in the chamber. The unit also includes a donor roll (40) including an electrically non-conductive circumferential surface having a central region (104) and opposed marginal regions (102,106) disposed on either side of the central region (104) with the diameter (110,114) of the central region (104) being less than the diameter (110,114) of the opposed marginal regions (102,106). The donor roll (40) is spaced from the latent image to form a development zone. The unit further inclues an electrode member (41)which is positioned in the development zone adjacent opposed marginal regions and spaced from the central regions of the donor roll. The electrode member is electrically biased to detach toner particles from the donor roll to form a toner powder cloud in the development zone with toner particles from the toner cloud developing the latent image.

Abstract: A method for controlling a ventilating apparatus (11) for ventilation and temperature control of accommodations, e.g. in vessels. The apparatus is connected to at least one ventilation channel (10) and comprises means for volume control of the air flow to the accommodation, means for temperature control of the air flow to the accommodation, and a control unit (13) for controlling the flow and temperature, for adaption to a desired temperature level. The control unit (13) is manipulated for reduction of temperature from a value of origin to a desired value which is at a certain distance from said value of origin. The flow controlling means and the temperature controlling means are adjusted for a rapid reduction of the temperature during a predestinated period of time. After this period of time has lapsed, these means are reset to provide a temperature level which is lower than the original value which existed before the reduction in temperature was started.

Abstract: The load signal device provides a load signal representing the actual air mass supplied to the engine for each stroke using signals representing the momentary air flow through the air intake pipe, which are summated over a given angular range of the engine crankshaft. The load signal is used directly for calculating the quantity of fuel to be injected in a given engine rev range and throttle position range, with correction of the last value provided for the latter range in dependence on the revs for a second rev range, to provide a replacement load signal.

Abstract: An encoding apparatus uses a vector quantization encoding method for encoding indexes of codewords, which supply a scalar quantized code of a maximum scalar product value of each code word in a code book, and its maximum scalar product value to a vector component of an input image inputted from an image sensor, so as to output the encoded indexes. A scalar product value calculating circuit in the encoding apparatus has scalar product value calculating sections, which are composed of an analog circuit having a code component capacitor corresponding to each code component, a differential amplifier and a feedback capacitor, corresponding to each codeword, and the scalar product values of the input vectors are calculated in parallel by the scalar product value calculating sections. In such a manner, when the analog calculation is made, the scale of the circuit can be decreased and the power consumption can be lowered. Therefore, unlike the case where the calculation is made after A/D conversion, it is possible to avoid a problem that the number of times of calculations and the power consumption are remarkably increased due to increases in the number of dimensions of the input vector and the number of gradations. <IMAGE>

Abstract: In a method of driving vibrating compressors having such a construction that a-c voltage is fed to a vibrating compressor by converting d-c voltage into a-c voltage with two MOS-FETs, the two MOS-FETs as switching elements are driven to convert d-c voltage into a-c voltage by changing the ON time of each of the MOS-FETs corresponding to suction and compression strokes in one cycle of the vibrating compressor to improve the operating efficiency of the vibrating compressor. To this end, suction and compression time in one cycle of the vibrating compressor is changed by means of a timer IC.

Abstract: An impingement freezer (1) having a zoned freezing chamber (10) in which the temperature of each zone (22,24,26) is independently controllable so that the temperature profile within the impingement freezer (1) is coldest at a zone (22) adjacent the outlet and warmest at a zone (26) adjacent the inlet (12) for maximum thermodynamic usage of the refrigerant. Additionally, the velocity of each of the impingement jets is independently adjustable from zone to zone so that in the zone adjacent the entrance (12) of the freezing chamber (10), the impingement jets can be adjusted to have maximum velocity to produce maximum heat transfer coefficients and thereby an acceptable rate of cooling within the impingement jet freezer (1). Impingement jets are formed within nozzles (28-48) that are tapered in two orthogonal directions to prevent frost build-up. Circulation within the impingement jet freezer (1) is produced by venturi-like devices (74-84) driven by vaporization of incoming refrigerant.

Abstract: The invention has the object of offering a phase synchronization system for wavelength division multiplexed bi-directional communications systems which can perform high-precision phase synchronization between a master device and a slave device without being affected by chromatic dispersion within the optical transmission medium. Fig. 1 is a block diagram showing the structure of an embodiment of the phase synchronization system of the invention. The phase synchronization system switches between phase difference measurement between optical signals of two different wavelengths which propagate in opposite directions and phase difference measurement between optical signals of the two different wavelengths which propagate in the same direction. By comparing the data indicating the phase difference, the system determines the delay time between the master device and the slave device.

Abstract: A method and an apparatus of the invention may evaluate the
performance of an electric appliance by: providing within assembly lines a
test line capable of operating the appliance in a simulation mode and
measuring at least one physical quantity observable for the appliance in the
simulation mode; automatically measuring the values of said physical
quantity during said simulation mode a predetermined time after the start
up of the simulation mode; and determining whether a currently measured
value of the physical quantity falls within a first reference range having
preset upper and lower limits until the number of the measurements reaches
a first predetermined number, and, after the number of the measurements
has reached said first predetermined number, whether the currently
measured value falls within a second reference range which is calculated
from a predetermined number of consecutive measurements that precede the
current measurement. With this method, the manufacturing line may
adequately incorporate a performance test line which may carry out required
tests without interrupting assembly lines, thereby improving its production
efficiency.

Abstract: A waveguide structure which is implemented in silica and doped silica includes at least one path region (53) and a confining region (52,54,55). The confining region (52,54,55) is in two regions. The first region (52,54), which is preferably formed of undoped silica and deposited by chemical vapour deposition so that it is never melted, surrounds the path region (53). The second region (55) is doped with a melting point depressant so that it has a lower melting point than the first region (52,54). The first region(52,54) provides a stabilising skeleton when complicated structures. The use of a skeleton facilitates the preparation of 3-dimensional waveguides with path regions which share a common confining region, preferably of uniformed refractive index. The path regions may be located at two or more different levels.
