Title: Ink jet recording apparatus
Inventor: YOKOI KATSUYUKI
IPC: B41J2/01
Filed: 1994-09-02
Abstract: PURPOSE: To well realize high density in respective recording modes in an ink jet recording apparatus having two recording modes different in resolving power. CONSTITUTION: In a recording mode of high resolving power, a colorless treatment soln. insolubilizing or flocculating ink and a colorant thereof is emitted to be mixed with ink on a recording medium.

IPC: H01M10/42
Filed: 1994-08-11
Abstract: PURPOSE:To accurately simulate the capacity variation of a battery caused by discharge by variably controlling resistance corresponding to the resistance of electrochemical reaction according to the capacity variation of the battery. CONSTITUTION:Variable resistance G-Rc corresponding to resistance of electrochemical reaction and constant resistance Ro-S corresponding to ohm loss are connected in series to the constant voltage source Eo-S of electromotive force, and a battery capacity capacitor charge/discharge power source F1 and a battery capacity capacitor C1 are connected in parallel. The variable resistance G-Rc is variably controlled by the voltage of a node 4 with potential same as that of the capacitor C1, and the variable resistance G-Rc is varied according to the capacity variation of a battery.

Title: Phase controlled type oscillator
Inventor: CHIBA YOSHIYUKI
IPC: H03L7/22
Filed: 1989-08-15
Abstract: PURPOSE:To lower the frequency handled by a mixer and a programmable divider and to attain local oscillation with a small frequency division and a highly pure carrier frequency by interposing a prescaler between a frequency oscillator and the mixer in a phase controlled oscillator. CONSTITUTION:A phase comparator 2 compares the phase of a reference signal with the phase of an output of a programmable divider 7 and outputs its difference voltage. The oscillating frequency of a frequency oscillator 4 is controlled in response to the output difference voltage. The operation of a synthesizer outputting a desired different fLO is implemented by varying the frequency division of the programmable divider 7 with a control signal. Since an intermediate frequency band of several tens MHz through a mixer 6 is inputted to the programmable divider 7, a smaller frequency division number in comparison with a conventional device is enough, the local oscillating frequency with high carrier purity is obtained.
