Inventor: MORIYA NOBUO
IPC: C07C37/84
Filed: 1992-05-29
Abstract: High purity, crystalline adduct of bisphenol A and phenol is produced multi-stage crystallization of a phenolic slurry of bisphenol A with a crystal separation and washing step being interposed between each of the two stages. Each of the crystallization stage includes a series of crystallization towers operated at decreasing temperatures. The crystallization of the slurry is performed by continuously discharging a portion of the slurry from each of the crystallization towers, introducing the discharged slurry into one or more coolers and then recycling the cooled slurry to the tower. Another portion of the slurry in each crystallization slurry is continuously discharged, heated for dissolving fine crystals of the adduct and then recycled to the crystallization tower so that large crystals are grown in each of the crystallization steps. An apparatus having a plurality of coolers and suitable for effecting the above crystallization is also disclosed.

Abstract: A switching circuit is provided for protecting semiconductors such as switching transistors against transients occurring in system voltage provided by an associated source of electrical energy. The circuit uses a switching device (18), including any number of avalanche transistors, to apply electrical energy from the source thereof to a load (20) with which it is in series. A voltage sensor (12) monitors the system voltage and generates a transient detection signal whenever it detects a voltage transient. A processing device (16) is used to process the transient detection signal and generate an output control signal that switches the avalanche transistors into a state of conduction so that the system voltage, including any voltage transients, appears substantially entirely across the load. Using avalanche transistors as switching transistors provides a significant margin of time for the detection, processing and switching actions to occur without damage being done to the switching transistors by a voltage transient.

Abstract: A water-resistant electrical connector includes a housing (10) having at least one cavity (11) dedicated to receive a terminal fixture (30) and at least one cavity (21) which is configured to prevent a terminal fixture (30) from being inserted therein. Although both of the cavities (11, 21) are open at opposite ends of the housing (10), a wall (10a) closes up the cavity (21) which is not to receive a terminal fixture (30) constituting an electric circuit. This wall (10a) prevents water from passing through the cavity (21) from one side of the housing (10) to the other. A fin (27) also extends across this cavity (21) from an open end of the cavity (21) to the wall (10a) to thereby prevent a terminal fixture (30) from being inserted in the cavity (21) and into contact with the wall (10a). A molding system can manufacture connector housings (10) having various combinations of the cavities (11) configured to receive a terminal fixture (30) and cavities (21) which prevent a terminal fixture (30) from being inserted therein. The molding system includes a fixed mold (65), a movable mold (67), and pairs of mold pins (61, 62) which are detachably mountable to the molds (65, 67). One pair of the mold pins (61, 62) will form a cavity (11) configured to receive a terminal fixture (30) while another pair of the mold pins (72, 74) will form a cavity (21) which will prevent a terminal fixture (30) from being inserted therein. The respective pairs of the mold pins (61, 62; 72, 74) are interchangeable so that the same molds (65, 67) can be used to manufacture various types of housings (10) depending on the circuit to which the connector is applied.

Abstract: A mapping determination method for obtaining (41) mapping F from an N-dimensional metric vector space  OMEGA N to an M-dimensional metric vector space  OMEGA M has the following steps to get the optimal mapping quickly and positively. In the first step, complete, periodic, Lm basic functions gm(X) according to the distribution of samples classified into Q categories on the N-dimensional metric vector space  OMEGA N are set. In the second step, a function fm(X) indicating the m-th component of the mapping F is expressed with the linear sum of the functions gm(X) and Lm coefficients cm. The third step provides Q teacher vectors Tq = (tq,1, tq,2, tq,3, ..., tq,M) (where q = 1, 2, ..., Q) for the categories on the M-dimensional metric vector space WM, calculates the specified estimation function J, and obtains the coefficients cm which minimize the estimation function J. In the fourth step, the coefficients cm obtained in the third step are stored in memory (42). <IMAGE>

Abstract: A radio frequency (RF) transceiver includes a direct modulation transmitter and single down-conversion receiver for operation in a time-division-duplex (TDD) telecommunications environment. A single RF signal source, in the form of a phase-locked-loop (PLL), is used on a time-shared basis to provide both the carrier signal for the transmitter and the local oscillator (LO) signal for the receiver. In the transmitter, direct modulation is effected by modulating a voltage-controlled oscillator (VCO) in the PLL with a burst of the transmit data while opening the loop and holding the loop feedback tuning voltage constant. In the receiver, a self-adjusting comparator threshold is provided for automatically setting and adjusting a demodulated signal comparison threshold used in retrieving the data and data clock from the demodulated receive signal. The interface between the transmitter and receiver and the host controller provides the control signals needed for the time-sharing of the single RF signal source, the proper programming of the PLL for the different transmitter carrier and receiver LO frequencies, the PLL loop control for the direct modulation of the VCO, and the enablement, or powering down, of the transmitter and receiver sections to minimize transceiver power consumption.
