Inventor: ARAHARA KOZO
IPC: B65G54/02
Filed: 1990-05-24
Abstract: PURPOSE:To enhance a recording image forming speed by a method wherein an adhesive material is reduced in adhesion by a first electrode to be transferred to a second electrode by applying a voltage to the adhesive material a plurality of times. CONSTITUTION:With power sources 21, 210, and 211 turned ON, a first roller 11 becomes a cathode, and a second roller 12 and an auxiliary rollers 110 and 111 become an anode. Simultaneously, the auxiliary rollers 110 and 111 come close to the first roller 11 to come into contact with an adhesive material 100. Firstly, the adhesive material 100 on the first roller 11 is applied with an voltage between the first roller 11 and the auxiliary roller 110 with the rotation of the first roller 11; next, it is applied with a voltage between the first roller 11 and the auxiliary roller 111; and lastly, it is applied with a voltage between the first roller 11 and the second roller 12. At this time, the adhesion of the adhesive material 100 is reduced on the side of the first roller 11. Therefore, the adhesive material adheres only to the second roller 12 by the rotation of the first roller 11 and the second roller 12. In this manner, the adhesive material 100 is all transferred to the second roller 12, substantially.

Title: Alarm device
Inventor: TERAO HIROYUKI
IPC: G08B21/24
Filed: 1995-06-02
Abstract: PURPOSE: To enable a user to judge whether an alarm is caused by radio interference when the alarm is reported by judging whether or not there is the possibility of the radio interference and specifying whether or not there is the radio interference unless a sent discrimination code matches the ID code set in a receiver. CONSTITUTION: A radio signal sent from a transmitter 1 is tuned and detected by an antenna 3 and a reception part 4, and further demodulated and decoded into a code sequence of '0' and '1', which is outputted to a CPU 5.
