Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To permit anybody to easily wash rice without experience by providing the inner wall of a pot where water and rice are contained with a turbid degree marker for displaying the reference of a turbid degree in rice washing water. SOLUTION: The pot 7 of an electric rice cooker is provided with water level display lines 8 and 8 corresponding to a rice quantity on its inner wall, by which a boiled rice hardness is changed in accordance with liking. In this case, the turbid degree marker 9 for displaying the reference of the turbid degree in rice washing water is also attached. The turbid degree marker 9 is formed by drawing in a printed state in a pot material through the use of a fluororesin in the same way as that of the water level display line 8.  It is favorable that the marker 9 is formed to be a thin lattice state, for example and its printing density is made to be a color being similar to that of water where a rice washing water color changes from a floating white color into a light white color at the time of washing rice and becomes clear to same extent so as to be a degree where 1 cm-depth under water can be seen. Thus, it is judged that rice washing is proper when rice washing water becomes almost the same color as the turbid degree marker even by unexperienced person.

Title: Controller for magnetic disk device
Inventor: MIYAKE YOSHIHIKO
IPC: G11B33/14
Filed: 1986-12-12
Abstract: PURPOSE:To prevent head crash by providing a crash prevention control means which causes a magnetic head to seek at least to two specific cylinders which are set in the maximum floatation area of the magnetic head in a seek range after a set time passes and removes dust and dirt adhered on a head slider surface. CONSTITUTION:The crash prevention control means 4 causes the magnetic head 13 to seek after previously set time passes irrespective of a seek instruction from a host unit. Furthermore, the magnetic head 13 is caused to seek at least to two specific cylinders which are set in the maximum floatation area in the seek range. While the magnetic head 13 is in a seek action for writing into/ reading from the magnetic disk disk 11, dust and dirt adhered to the head slider surface can be shaked off. Furthermore, the magnetic head 13 does not seek from the cylinder on an outer peripheral side with a large floatation quantity to that on a central side with a small floatation quantity in a state that dust and dirt still adhered to the head slider surface. Thus, head crash can securely be prevented due to the seek action.
