Abstract: The present invention relates to a method for preparing esters of fatty acids or hydroxy fatty acids with isopropylidene derivatives of a polyglycerol from fatty acid alkyl esters, mono- or polyhydroxy fatty acid alkyl esters with C6-C22 in the fatty acid component and C1-C4 in the ester component, which are reacted in alkaline medium with one or more isopropylidene derivatives of a polyglycerol. The reaction is carried out  at temperatures of 140-220 DEG C and under vacuum up to 950-5 mbar. The resulting C1-C4-alcohol is removed by distillation, and the reaction product is purified. 
<??>The invention also relates to the use of the esters of fatty acids or hydroxy fatty acids with mono- and/or diisopropylidene derivatives of polyglycerol as intermediates for preparing nonionic surfactants, as solvents or solubilisers and for cosmetic preparations and skin-care agents.

Abstract: A portable electronic device comprising an integrated circuit card (10), which incorporates a data memory (32) and CPU (30) and is externally provided with a keyboard (18) and a liquid crystal display (16). The data memory (32) stores a variety of data which respectively indicates the maximum amount allowed for executing transactions during an effective term, the effective term for transactions, the maximum amount for transactions that can be renewed each effective term, and the effective term between renewals. In addition, the IC card (10) also incorporates a clock circuit (36) which generates data indicating the current date. When the card holder initiates a transaction using the IC card (10), the CPU (30) compares the data related to the current date with the effective term for transactions. If the CPU (30) identifies from the result of comparison that the present date is outside the effective term for transactions, the CPU (30) then automatically renews the effective term for transactions and updates maximum amount allowed for transactions by applying data indicating the effective term applicable to renewal and the maximum amount for transactions to be renewed.

Abstract: A FSK data signal voltage inputted from an input terminal 4 is converted into current by a resistance R₁ and then the current is differentially amplified with respect to a reference voltage of a capacitor C₁ in a second differential amplifier circuit 2. As a result, a waveform-shaped signal is generated from each collector of transistors Q₂ and Q₃ constituting the second differential amplifier circuit 2. Meanwhile, the FSK data signal inputted from the input terminal 4, after an alternating current signal component thereof is removed, is applied to a third differential amplifier circuit 3 wherein a difference between the signal and the reference voltage of the capacitor C₁ is amplified. Charging/discharging the capacitor C₁ is controlled in response to an output of the third differential amplifier circuit 3.

Inventor: BASSETT JOHN A
IPC: H02M3/28
Filed: 1990-11-13
Abstract: A two switch, DC/DC converter provides sufficient inductive energy storage at the termination of the "on" period of each switch to alter the charge on the intrinsic and stray capacitance of the combination of switches producing zero voltage across the alternate switch prior to its turn on. A short dead-band between the turn on pulses provided by the control circuit allows time for this transition. Thus the energy stored in the capacitance of the switches is returned to the source and load rather than being dissipated in the switching devices. This greatly improves the efficiency of the converter particularly when operating at high frequency. The unique topology of the converter provides other new and useful characteristics in addition to zero voltage switching capability such as operation at constant frequency with pulse-width-modulation for regulation, quasi-square wave output current, and the ability to integrate the magnetic elements with or without coupling.
