Title: Burner re-ignition control method for grain drier, etc.
Inventor: MIYAZAKI KEIICHI
IPC: F26B23/02
Filed: 1991-11-22
Abstract: PURPOSE:To eliminate the interruption of hot air drying by preventing temporal combustion interruption by re-ignition upon an accidental fire being produced during combustion. CONSTITUTION:Once a combustion sensor 2 detects an accidental fire during combustion, power is supplied to an ignition device 3 owing to that detection, and if ignition does not take place in a predetermined time, the operation is switched to draft drying. In contrast, if ignition takes place in a predetermined time to permit the combustion sensor 2 detect an accidental fire one time for example, power supply to the ignition device 3 is interrupted, and if such an accidental fire is detected two times or more, power is supplied to the ignition device 3 until the drying is completed for hot air drying. Temporary combustion interruption is eliminated by re-combustion following the accidental fire. Thus, interruption of the hot air drying is avoided.

Title: Image forming method
Inventor: YAMANE KENJI
IPC: G03G13/08
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To form a stable image over a long term, especially, even under environment such as high temperature and high humidity by using magnetic grains with carrier having a specified grain diameter. SOLUTION: The surface shape of the carrier grain is fixed according to the size of the grain diameter. Namely, in the case the grain diameter is small, a rugged part on the carrier surface becomes large; on the contrary, in the case the grain diameter is large, the rugged part becomes small and the surface shape becomes smooth. The grain diameter is controlled to be 0.2-10μm. When a latent image on a photoreceptor is developed, not only toner but also carrier are brought into contact with the photoreceptor in the case of two-component developer. By controlling the shape of the carrier, the grinding effect of the carrier itself is achieved, so that the photoreceptor is finely ground, consequently, water adhering or absorbed in the photoreceptor is removed.  As for a cleaning mechanism for removing the toner remaining on the photoreceptor 2; it is desirable that a cleaning blade 1 is held by a holder 3 and an angle θ1 formed by the photoreceptor 2 with the holder 3 is 10-90 deg..

Abstract: PURPOSE: To support a wide temperature range of a liquidlike substance to be filled by a single pump by serially providing two bellows which are sectioned by three bulkheads each having a check valve and reciprocatingly driving a middle bulkhead. CONSTITUTION: During a process wherein a bulkhead 6 reciprocatingly driven by a driving means 15 approaches a bulkhead 5 and the bulkhead 6 moves away from a bulkhead 7, a bellows 11 shrinks to have its internal pressure raised while a bellows 12 expands to have its internal pressure lowered. Therefore a check valve 8 and a check valve 10 close while a check valve 9 opens, so that a liquid-like substance in the bellows 11 reaches the bellows 12 via the check valve 9. On the other hand, during a process wherein the bulkhead 6 moves away from the bulkhead 5 and the bulkhead 6 approaches the bulkhead 7, the bellows 11 expands to have its internal pressure lowered while the bellows 12 shrinks to have its internal pressure raised.  Therefore the check valve 8 and the check valve 10 open while the check valve 9 closes, so that the substance on a flow-in side 3 flows via the check valve 8 into the bellows 11, and the substance in the bellows 12 is sent out through the check valve 10 toward a flow-out side 4.
