Title: Evaporative fuel handling device for internal combustion engine
Inventor: HIRANO NOBORU
IPC: F02M25/08
Filed: 2000-11-24
Abstract: PROBLEM TO BE SOLVED: To ensure a desirable purge flow rate according to the operating state of an internal combustion engine by improving the durability of an electric pump and accelerating desorption of evaporative fuel from a canister. SOLUTION: Heat generated when a motor part 45 of the electric pump 40 drives a pump part 41 thereof can be used to heat an adsorbing body 31 in the canister 30 and thus accelerate desorption of evaporative fuel adsorbed on the adsorbing body 31. The rotational frequency of the electric pump 40 for ensuring a desirable purge flow rate can be thereby reduced. The motor part 45 of the electric pump 40 can be, at the same time, cooled because the heat of vaporization of the evaporative fuel is absorbed from about a housing, and prevented from overheating. The power consumption of the electric pump 40 can be reduced and the durability thereof can be improved.

IPC: B41J29/38
Filed: 2000-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a printing system without the need for reprinting operation from an application by storing automatically printing data into a host when an image forming device does not allow printing. SOLUTION: In the printing system, at first, the application initiates the printing, and then it is determined whether the device allows printing by acquiring information (step 10). If the device allows printing, the printing data is transmitted to the device (step 11). On the other hand, if the device does not allow printing (No, in step 10), the data is stored into the host device (step 12) to end printing processing. Accordingly, the printing processing can be ended without user's awareness even in the state that the device does not allow printing.

Title: Fixing device
Inventor: HASEGAWA KAZUHIRO
IPC: H05B3/00
Filed: 2000-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent defective fixing by reducing the overshoot of the surface temperature of a roller for fixation even when a copy operation is temporarily suspended in a serial copy by the control of image adjustment or the like. SOLUTION: The surface temperatures of a fixing roller and a pressure roller are detected during the standby of a fixing device, and the on-off operation of each heater is repeated to control the surface temperatures in a fixed range (period Ea of Figure 4). A heater is turned on continuously, because the surface temperature continues to lower when a copy is started (Eb). After the surface temperature reaches 180 deg.C of a temperature control temperature (Ec), the on-off operation of the heater is repeated similarly. The overshoot is caused when control to suspend temporarily a serial copy operation is started in this state (Ed).  In order to prevent the overshoot, the surface temperature is detected at the time of the restart of the copy operation (period Ee), and when the surface temperatures exceed 180 deg.C, the temperature control temperature is changed to be lowered by 10 deg.C, and thereby the lighting timing of the heater is delayed to suppress the total heat given to the roller.

Title: Digital camera and its operation control method
Inventor: ITO KENJI
IPC: H04N5/378
Filed: 2000-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a digital camera that can quickly read a video signal from a CCD without deteriorating the resolution. SOLUTION: When a zoom magnification is 1.25 or less, the number of pixels being a half of the total number of pixels are thinned in a vertical transfer path so as to halve the number of pixels in a vertical direction and pixels are mixed in a horizontal transfer path of the CCD so as to halve the number of pixels in a horizontal direction. When the zoom magnification reaches 1.25 or over at a time (t), the pixels in the horizontal direction are not mixed and the horizontal transfer path of the CCD is driven so that the number of the pixels in the vertical direction is 1/4. The number of pixels in the horizontal direction of an image represented by the video signal outputted from the CCD reaches the number of pixels in the horizontal direction of a display screen of a display device or over.  Since interpolation of pixels for display is not needed, the display device can display the image with high resolution.
