Title: Power source
Inventor: SUZUKI AKITSUGU
IPC: H02J7/00
Filed: 1991-09-19
Abstract: PURPOSE:To prevent a shortening of a life of a battery by measuring a voltage of an AC adapter taken out by a voltage detection terminal and stopping charging of a charger when it becomes different from a predetermined value. CONSTITUTION:An AC adapter 2 is connected to a power source circuit 1 by a voltage detection terminal 8. The voltage of the adapter 2 is divided by resistors 9a, 9b, and input to a voltage detector 10 provided in the circuit 1. The detector 10 measures the voltage, sends a signal to a charger 5 if the voltage value is different from a predetermined value, and applies a command so as not to charge a battery 4 by the charger 5. Thus, when an AC adapter 2 except the designated adapter is erroneously connected, charging of the battery 4 can be prevented, and a shortening of a life of the battery 4 can be prevented.

Title: Liquid drop jetting apparatus
Inventor: IINO SHUJI
IPC: B41J2/06
Filed: 1987-09-24
Abstract: PURPOSE:To enable printing density to have gradation, by a method wherein a shape of magnetic fluid is varied by variation of magnetic field set to the magnetic fluid made to exist in a nozzle, and fluid resistance of fluid to be discharged is controlled. CONSTITUTION:In the case where a jetting amount of ink is intended to be increased, magnetic poles of three pairs of electromagnets 4a, 4b-6a, 6b are so switched that counter poles become same poles to each other and adjacent poles become different pole to each other. Then, a synthetic magnetic field of three pairs of electromagnets is concentrated near a wall surface of a passage in a nozzle, and magnetic fluid is deformed according thereto. Consequently, a passage area where ink can flow is enlarged, and the jetting amount of ink is increased. Besides, in the case where the jetting amount of ink is intended to be decreased, when the counter electric poles are made the same poles to each other by applying current only to a central pair of electromagnets 5a, 5b, the magnetic field is distributed near the wall surface of the passage in the nozzle and however, a degree of concentration is moderated. Since the magnetic fluid is consequently deformed according to a distribution of the magnetic field, fluid resistance to ink is increased, and the the jetting amount of ink is decreased.
