Title: Imaging apparatus
Inventor: SUZUKI TOSHIYA
IPC: B41J5/30
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To provide an imaging apparatus in which availability is enhanced when a printer is reset or settings of print environment is altered automatically by a reset signal or a print environment settings altering signal from a host. SOLUTION: A printer receives a reset command by communicating data with a host and if a print job includes an existing page, i.e., print data, before receiving a reset command, existing pages are printed entirely. Subsequently, the printer is brought temporarily into off line state and stores data in a receiving buffer, i.e., an RAM, temporarily in an NV-RAM before being reset. When reset is completed, the printer returns data transferred to the NV-RAM entirely back to the RAM to bring about the state prevailing before being reset thus bringing about on line state between the host and the printer. Even when the printer is shared among a plurality of hosts or users, it can be reset without taking account of the using state of other hosts or users.

Title: Hydraulic traveling vehicle
Inventor: ICHIMURA KAZUHIRO
IPC: B60W10/10
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To restrain variation in vehicle speed without conducting pump inclination in conducting the inclination control, in which when a traveling load is more than a designated value, the motor inclination is increased, and the high horse power operation control in which the engine rotating speed is increased under a prescribed condition. SOLUTION: In the case where the high horse power operation mode is set, when the traveling pressure is more than a designated value and an accelerator pedal 22 is operated fully, the rotating speed of the engine is increased, and the inclination of a hydraulic motor 1 is increased. Accordingly, when the engine rotating speed is increased, the motor inclination is increased simultaneously, so that the variation in vehicle speed can be prevented, without having to reduce the flow of the pump 3. Thus, a pump regulator 11 can be constructed simply to conduct only the horse power control.
