Title: Rice cooker
Inventor: BETSUSHI TOKUJI
IPC: A47J27/00
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a rice cooker where safety is improved by preventing getting scald due to steam jetted from a steam hole during cooking. SOLUTION: A material detection means 22 for detecting a material is provided in the neighborhood of the steam hole 4a, and a pressure governor 14 (steam route disconnection means) and a weighting means 18 (steam route disconnection means) capable of disconnecting a steam ejection route 15 is provided at the steam ejection route 15. In the case of deciding that the material is positioned in the neighborhood of the steam hole 4a based on a signal from the material detection means 22 during rice cooking, a microcomputer 8 (control means) interrupts rice cooking control and disconnects the steam ejection route 15 by the pressure governor 14 and the weighting means 18.

Title: Lane deviation prevention device
Inventor: MATSUMOTO SHINJI
IPC: B60R21/00
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a lane deviation prevention device not giving uncomfortable feeling to a driver when a white line becomes possible to be recognized in a state where the white line can not be recognized, or in the state of the lane deviation at the start of the control. SOLUTION: Even though it is in a lane deviation state where a deviation estimated value XS based on a lateral displacement X detected with a camera is beyond a deviation decision threshold, the lane deviation prevention control is interrupted if the white line cannot be recognized. When a variation |XS(n-1) - XS(n) | of a deviation estimated value has become beyond the decision threshold value LXS by recognizing the white line in the state where the lane deviation prevention control is interrupted, a deviation avoidance control forbidding flag FCA is set to '1' and a yawing moment Ms is set to '0'. Thereby, the lane deviation prevention control is restricted to start in a large amount of control by forbidding the control.

Title: Printer and print cartridge for use therein
Inventor: TANAKA SHINJI
IPC: B41J29/38
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To protect a printer against damage due to inappropriate use of a print cartridge by judging inappropriate use thereof. SOLUTION: When a decision is made that an ink cartridge is inappropriate for a printer based on an ID read out from a storage element of the ink cartridge (S100, S102), inappropriate use of ink cartridge is displayed (S104). When it is appropriate, residual quantity of ink read out from the storage element of the ink cartridge is compared with -5%, i.e., a threshold value being set while taking account of operational error in the residual quantity of ink or variation in the filling quantity of ink (S106, S108). If the residual quantity of ink is not higher than -5%, a decision is made that the ink cartridge deviates from the range of appropriate use and inappropriate use of ink cartridge is displayed. Since the possibility of inappropriate filling of ink is high in this case, print processing is limited in order to prevent clogging of a print head.

IPC: G03G15/08
Filed: 2001-12-03
Abstract: PROBLEM TO BE SOLVED: To discriminate whether a detachable process unit is suitable to a device main body by a simple mechanism. SOLUTION: Denoting the number of divisions of a gear surface 104 of a photosensitive drum 55 as (n), (n-1) kinds of marks 105 can be generated so that, for example, a mark 105 of (a) provided on the gear surface 104 is 2/8 time and a mark 105 of (b) is 3/8 time as large as the gear surface 104. In either case, a mark tip part 105a in a rotational direction shown by (G) is at the positioning position of a rotational phase. This is detected by a sensor to decide specifications of the photosensitive drum 55 from the on-to-off period of the detection signal. Namely, a printer of a company A judges that the mark of a photosensitive drum of the company A is proper. A developing unit is similarly judged from the slit width of an encoder for remaining tone amount detection.  The machine type code of a developing unit U2 which is written to an EEPROM can be changed to make it possible to load a developing unit U2 having similar functions and specifications in other printers.
