Title: Processing system of japanese language
Inventor: JIYOSEFU PAIKON
IPC: G06F17/22
Filed: 1993-06-29
Abstract: PURPOSE: To delete erroneous reading and to output the correct reading of Japanese pronunciation by dividing a text into Chinese characters (KANJI), Japanese syllabary (KANA) and square forms of KANA, analyzing that character information for the unit of η-gram and performing retrieval for the unit of η-gram dictionary along an optimum route from the backpoint of the text to the leading character. CONSTITUTION: When referring to the upper right figure, a η-gram unit (j) function of 'side' (whose reading is 'gawa' in Japanese) of 'shop side' (whose reading is 'mise-gawa' in Japanese) is retrieved from '3' to '1' and when 1g is provided, the η-gram (j) to be returned is defined as '1'. Next, when the lower left figure is referred to and i=K4 is defined as a current η-gram, it is '1' and with this point as an origin, the word of 'head agent' (whose reading is 'so-dairiten' in Japanese) is retrieved from '4' to '1'. Then, when the word of 'agent' (whose reading is 'dairiten' in Japanese) is found out in the dictionary for the unit of 3gram, the η-gram unit to be returned is changed into '3'.  Further, when the remaining text of 'total' (whose reading is 'so' in Japanese) is retrieved, the η-gram becomes '1' and it is enough only to perform return for the unit of 1gram at K0 . Namely, when the η-gram dictionary is investigated and the best route is found out, the long KANJI idiom can be converted into proper KANA.

Title: Magnetic disc device
Inventor: MINAMI SHIGEO
IPC: G11B23/50
Filed: 1984-07-30
Abstract: PURPOSE:To prevent contact area and contact pressure from being changed because of wear of an earth pad by decreasing the cross section area of the earth pad than the cross section area of an edge of a spindle, adopting a type of material of the earth pad subject to wear than that of the spindle and using a coil spring having a smaller spring constant than that of a plate spring. CONSTITUTION:The press contact part of the earth pad 8 wears as time is elapsed by the turning of the spindle 3. Since the cross section of the earth pad 8 is formed smaller than the cross section area of the edge of the spindle 3, the contact area is unchanged even when being subject to wear. Since the type of material of the earth pad 8 is selected to be worn easily more than that of the spindle 3, the spindle 3 hardly wears and only the earth pad 8 wears practically and the change in the contact state due to the degree of wear is less. Since the spring constant of the coil spring 10 is small, the change in the pressure of the earth pad 8 onto the edge of the spindle 3 due to the wear of the earth pad 8 is less.

Filed: 1985-07-22
Abstract: PURPOSE:To provide a semiconductor device which can attain shortening of lead correcting time and elimination of special tools, by making leads, at least outer lead sections, of a shape memory alloy. CONSTITUTION:Around a semiconductor device 12, a plurality of leads 13 of shape memory alloy are provided. Electrode sections on the semiconductor device 12 and the leads 13 are electrically connected with bonding wire 14 respectively, and the semiconductor device 12 is sealed in a package. Since the leads 13 are made of shape memory alloy, the leads can be prevented from bending greatly in the IC manufacturing process.
