Title: Image forming device
Inventor: TAMURA SATOSHI
IPC: G03G15/14
Filed: 1994-01-11
Abstract: PURPOSE:To prevent a recording material carrying sheet from being partially deteriorated and to prolong the lifetime thereof by enhancing the strength at the position of the recording material carrying sheet corresponding to a pressing member in a direction substantially orthogonally crossed to the moving direction of the recording material carrying sheet in comparison with the position other than it. CONSTITUTION:When the tip of a recording material on which the transfer action of the desired number of toner images is finished arrives at a separating position, a separation and pushing-up roller and a separation pawl are respectively actuated and the recording material carrying sheet 5f is deformed. Then, the tip of the recording material is separated from the sheet 5f. Thereafter, the recording material is carried on the separation pawl and submitted to a fixing process. Since the sheet 5f is repeatedly deformed by the pressing member such as the separation and pushing-up roller in a separation process, the strength at the position of the sheet 5f corresponding to the abutting position on the pressing member is enhanced. That means, a sheet member 5p is stuck on the opposite surface of the sheet 5f to the carrying surface of the recording material in the direction orthogonally crossed to the moving direction of the sheet 5f so as to make the position thicker in comparison with the position other than it.

Inventor: TAKAHASHI HIDEO
IPC: F02D41/22
Filed: 1989-01-10
Abstract: PURPOSE:To prevent air-fuel ratio from becoming overrich at the time of starting an internal combustion engine by correcting an intake air flow rate based on the lapse of time from the throw-in of a power source to a hot-wire type airflow meter and operating a fuel injection quantity. CONSTITUTION:A fuel injection quantity operating means (b) calculates a fuel injection quantity based on an intake air flow rate detected by an intake air flow rate detecting means (a) composed of a hot-wire type airflow meter and engine speed. At the time of starting an engine immediately after throwing in a power source, however, the hot-wire type airflow meter (a) present an output voltage just as a large quantity of air is taken in due to the effect of a power source throw-in characteristic even though the actual intake air flow rate is low. Hence, the lapse of time from the throw-in of the power source to the airflow meter (a) is measured by a timer means (c) and the intake air flow rate outputted from the detecting means (a) is corrected by a correcting means (d) in accordance with the lapse of time. Thereby, the air-fuel ratio can be prevented from becoming overrich at the time of starting an internal combustion engine.

IPC: H04B7/12
Filed: 1982-01-11
Abstract: PURPOSE:To eliminate the effect of rainfall, by receiving beacon waves from a plurality of points and selecting a wave out of them suitable for the directivity control of antenna. CONSTITUTION:In installing beacon stations at two points apart by >= several tens of kilometers, the probability that the weather at both the points at the same time is very less. A satellite monitors the electric field intensity of the beacon waves incoming from a plurality of points. When the electric field intensity of a signal using as the beacon is decreased and is a predetermined  threshold level, the satellite changes over the beacon to the other beacon wave.  Even if the reception of one wave is deteriorated due to rain or an accident,  the antenna is directed to a desired direction correctly. Further, the range of  the two points (sevral tens of killometers) is within a range of error to the  directivity of the antenna mounted on the satellite.
