Title: Power supply
Inventor: MATSUURA KUNIAKI
IPC: H02J50/10
Filed: 1990-10-24
Abstract: PURPOSE:To obtain a stabilized output voltage higher than the peak open voltage of a receiving coil by constituting a power supply of means for storing electric energy in the receiving coil, means for feeding the electric energy to a load, and the like. CONSTITUTION:Upon application of an AC voltage V1 from an AC power supply 1 onto an exciting coil L1, an electromotive force is induced in a receiving coil L2. A phase detecting circuit 3 detects zero-cross point of the AC voltage and a switching control section 4 turns a switching element SW1 ON in response to a zero-cross detection output. Consequently, a circulation current 12 flows through the receiving coil L2 thus storing electric energy therein. Upon elapse of a predetermined time, the switching control section 4 turns the switching element SW1 OFF while turns a switching element SW2 ON. Energy stored in the receiving coil L2 is then superposed on the electromagnetically induced electromotive force and fed through the switching element SW2 to a capacitor C where it is smoothed and then fed to a load 2.

IPC: H04Q11/04
Filed: 1991-10-31
Abstract: PURPOSE:To improve the multiplexing efficiency by selecting a D channel, a channel time slot and a bit location. CONSTITUTION:A coincidence circuit 26 generates an output of a level '1' when a count of a counter 25 is equal to a D channel bit interval of a decoder 23. The phase of the output is shifted by a half at a flip-flop 28 to obtain a head bit location of a D channel corresponding to a mounted slot. A coincidence circuit 27 generates an output of level 1 when the count of the counter 25 is equal to an M channel bit interval of the decoder 24. The phase of the output is shifted by a half at a flip-flop 29 to obtain a head bit location of an M channel corresponding to a mounted slot. Thus, the timing designating the time slot and bit location of the D and M channels is generated from a frame pulse and a given channel pulse in this way to implement multiplexing/demultiplexing of each of channel data.

CONSTITUTION:In supplying an ammonium sulfate solution as a by-product in production of lactam to an ammonium sulfate crystallization can and carrying out concentration for separating out and recovering ammonium sulfate crystals, evaporation-concentration is carried out so that the slurry concentration of the solution in the can may not exceed the supersaturation solubility curve. By keeping the solution in the can in a state where the amount thereof extracted is lowered while preventing generation of excess crystalline nuclei, the residence time of the ammonium sulfate crystals in the crystallization can is prolonged so as to grow fine particle ammonium sulfate crystals to a limit. The amount of the solution in the can extracted is then increased to reduce the amount of the crystals held in the can and the resultant state is kept till a limit where the ammonium sulfate crystals remaining in the can can cancel the supersaturation. The amount of the solution in the can extracted is subsequently reduced so as to grow the next fine particle ammonium sulfate crystals. By repeating the above mentioned processes, the objective coarse granular ammonium sulfate crystals having a uniform granular size of about 2-5mm.
