Title: Digital type phase locked circuit
Inventor: SUGIMORI AKISHI
IPC: H04L27/227
Filed: 1982-06-21
Abstract: PURPOSE:To constitute a titled circuit of a gate IC and a counter IC easy to obtain, by comparing the phase between an input signal and an output frequency signal of a digital control transmitting signal and transmitting a detected output in response to the phase lead and phase lag. CONSTITUTION:When a signal at an input terminal 1 is not synchronized with an output of a digital control oscillating circuit 11, a signal at an OUT terminal of a lock detecting circuit 14 is ''1'' and a primary loop feeding back an output of the oscillating circuit to a phase detecting circuit is formed. When the initial phase locking is finished with this primary loop, the signal of the OUT terminal of the lock detecting circuit 14 goes to ''0'' and the signal is changed over to the secondary loop leading the integration output to the oscillating circuit. This secondary loop erases a stationary phase error generated in the primary loop.

Title: Image formation device
Inventor: AKIYAMA SATORU
IPC: G03G21/00
Filed: 1991-05-14
Abstract: PURPOSE:To save the preheating time of a fixing device, and reduce a time necessary for forming an image in an image formation device to perform a thermo-fixing process. CONSTITUTION:When an image signal is entered in an image formation device, a controller 26 immediately sends an instruction to a printer engine 25 via a video interface 24, regarding the start of preheating a thermo-fixing unit. As a result, the fixing unit in an image processing section 20 is heated even in the course of completing image data generation from the entered image data, and a time before reaching a fixing temperature required for a fixing process can be shortened. Also, the heating of the fixing unit is stopped in a certain time after reaching the fixing temperature, and the temperature of the unit is lowered from the fixing temperature, thereby preventing the wear or the like of the unit due to excessive heating.
