Title: Voltage-controlled oscillator that operates with digital control load in phase-locked loop
Inventor: AAMATSUDO EICHI ATORISU
IPC: H03K3/354
Filed: 1993-11-17
Abstract: PURPOSE: To realize a phase locked loop operating with desired frequencies without depending on the fluctuation of temperature or a process. CONSTITUTION: This phase locked loop 10 operates without depending on the fluctuation of temperature or a process by digitally adding a load 38 to a VCO 22 until a desired operating frequency is obtained. Plural current mirrors 164-166 are controlled for increasing the switching currents of an invertor in a VCO so that the VCO can reach a high output frequency in a process in the worst case without delaying a response to a loop node voltage 18 of the VCO. A frequency range detector 34 monitors the output frequency of the VCO, transmits a control signal to a load control circuit 38, activates a digital load, and decrease the VCO to the desired operating frequency.

Title: Communication equipment
Inventor: TAKAHASHI TAKETO
IPC: H04N1/21
Filed: 1986-12-27
Abstract: PURPOSE:To simplify an operation procedure by discriminating the memory transmission and the original transmission by means of two methods of end of key timer and the depression of a start key and to reduce a cost by decreasing number of keys. CONSTITUTION:In reading an original and storing it once in a memory in a conventional facsimile equipment, the opposite party is called by the automatic calling and then the picture in the memory is sent (one mode), and the opposite party is called by the automatic calling and after the call connection is finished, the original is read and sent (the other mode). A 'memory storage key' is used conventionally to select the mode, but the operation procedure is complicated and the increase in the number of keys leads to cost-increase. In order to improve the defect above, the memory transmission and the original transmission are selected by discriminating at least one state among the elapse of prescribed time after the operation of the final key, end of designated mode, depression of communication start key and number of communication opposite parties.
