Abstract: The present invention provides a method for manufacturing polycarbonate in which an aromatic dihydroxy compound and a carbonic acid diester can be effectively subjected to melt polycondensation using a small amount of a catalyst, making it possible to manufacture polycarbonate having outstanding color matching, outstanding thermal stability, color-matching stability, etc., during molding, and outstanding water resistance. 
     The method for manufacturing polycarbonate of the present invention is characterized in that when an aromatic dihydroxy compound and a carbonic acid diester are subjected to melt polycondensation in the presence of a catalyst, the catalyst is used in the form of a catalyst solution dissolved or dispersed in the carbonic acid diester, this catalyst solution is added to the melt polycondensation reaction system, and the aromatic dihydroxy compound and carbonic acid diester are subject to melt polycondensation.

Abstract: An elastic jointing member 22 with an umbrella-like portion with an opening and a flat part is provided in a jointing portion between a recording head 21 and an ink tank 1. When the ink tank 1 is attached to the recording head 21, the umbrella-like portion of the elastic jointing member 22 is pressed against the ink tank and elastically deformed inward. As a result, an ink passage is formed which is airtightly sealed. In the process of pressing the umbrella-like portion against the ink tank, the umbrella-like portion comes in contact with the flat part, to thereby prevent air from staying in the ink passage. Protrusions or grooves may be provided between the umbrella-like portion and the flat part. With the protrusions or the groove, the umbrella-like portion is not glued to the flat part.

Abstract: A winner-take-all circuit for judging a channel receiving an analog signal having the largest or smallest value among multiple channels upon input of analog signals. Each basic circuit includes a detecting unit for comparing an input voltage with a reference voltage, and a feedback current generating unit for outputting a feedback current that determines a judging range in response to an output voltage from the detecting unit. The winner-take-all circuit also includes a tenth transistor serving as a common transistor to all the basic circuits. The tenth transistor secures, even when an input voltage is small, a current that should flow through a sixth transistor serially connected to the seventh transistor that determines an amount of a feedback current from the feedback current generating circuit. As a result, even when there are fewer  k  channels receiving input voltages having the highest level and slightly lower ones compared with all the  n  channels, a feedback current is secured in a sufficient amount to vary the reference voltage. In addition, the winner-take-all circuit of the present invention comprises analog circuits, thereby making the structure simpler compared with a counterpart that processes digital data.

Abstract: A PCS switching system where a wireless set registers on a base station regardless of whether the base station has capacity to complete a call for the wireless set. When an incoming call is received for the wireless set, a central computer providing overall control of the PCS system directs this call to a paging zone controller of a paging zone in which the wireless set is registered. If the base station does not have capacity to handle that call, the paging zone controller transmits a message via the base station and a paging channel to the wireless set informing the wireless set that a page is pending and that it must find a base station with idle capacity. The wireless set does this by listening to the paging channel until a base station is determined that has idle capacity. The base stations periodically transmit on the paging channel, and each of their messages includes the present capacity of the base station. The wireless set establishes communication with the new base station and ceases to be in communication with the original base station. Since the wireless set is already registered with the paging zone controller, it is not necessary for the paging zone controller to re-register the wireless set with the wireless switching network when the wireless set moves from one base station to another base station within the same paging zone.

Abstract: A Zener diode 16 is connected to each of single cells 10 of an electric double layer capacitor in parallel, and a resistor 18 is connected to each of the Zener diode 16 in series. Thus, in a case where a single cell 10 is excessively charged, when the bias voltage of the single cell 10 is equal to or higher than the Zener voltage, a discharge current flows through the Zener diode 16 connected to the single cell 10, so that the voltage decreases to the Zener voltage. Thus, it is possible to prevent the electric double layer capacitor from being excessively charged due to the dispersions in electrostatic capacity and internal resistance, and to stably accumulate electricity for a long time.

Abstract: A fluidized-bed classifier has a vessel (20) defining a space divided into an upper fluidized-bed chamber (22) and a lower gas chamber (23) by a perforated dispersion plate (21) having the shape of a funnel. Rising currents of a gas, such as air, are blown through the dispersion plate (21) into the upper fluidized-bed chamber to produce a fluidized bed of a particulate material over the dispersion plate. The lower gas chamber (23) is divided into a first gas chamber (23a) and a second gas chamber (23b) by a partition plate (29). The gas is supplied into the first air chamber (23b) so that rising gas currents of a velocity necessary for fluidizing coarse particles contained in the particulate material red into the vessel are blown from the first air chamber (23a) through the dispersion plate (21) into the fluidized-bed chamber. The gas is supplied into the second air chamber(23b) so that rising gas currents of a velocity lower than the velocity of the rising gas currents blown from the first air chamber (23a) into the fluidized-bed chamber (22) are blown into the fluidized-bed chamber so that coarse particles contained in the particulate material are not fluidized and does not flow together with fine particles into a fine particle discharge chute (28).

Abstract: The rear (32) and side (26,28) walls are integrally moulded onto the casting (10) forming the water tubes (14,16,18). At the tube entries and exits the casting uses respective wall plates to join the tubes together and so form water chambers (40,42) in conjunction with wall strips (36,38) and elements (52) for a sealing cover for the water chambers. Each side wall uses additional wall strips (44,46) to form a channel (48) connecting one of the chambers to an external feed or output connection (50). Wall passages and the holes between the wall strips at the plates and the chamber (30) side walls are under retractable slide control as inserted from the side in a slightly conical slide form. This expands the tube wall thickness slightly towards the centre. The tube fins (20) are designed into the structure of the basic casting.
