Title: Rotary head assembly of magnetic recording and reproducing device
Inventor: KANEKAWA HIROSHI
IPC: G11B5/52
Filed: 1989-01-07
Abstract: PURPOSE:To reduce the damage of a magnetic tape and the demagnetization of a signal track caused by a contact of the magnetic tape and a rotary cylinder by such an extremely simple constitution as the outside peripheral edge of the rotary cylinder is inclined. CONSTITUTION:When a rotary cylinder 4 rotates, an air film 11 becomes large in the front being near a window 402, therefore, by a large gap 12, an air flow escapes in great quantities into the cylinder, and abnormal floating of a magnetic tape 1 is prevented. Subsequently, when the air film 11 becomes small as it goes to be rear, the air flow which escapes into the cylinder decreases by the gap 12 which becomes small in accordance therewith, therefore, the magnetic tape 1 comes to scarcely come into contact with the rotary cylinder 4. This phenomenon is generated in the same way between the window 402 and the window 402, therefore, in the whole periphery of the rotary cylinder 4, the damage of the magnetic tape 1 and the demagnetization of a signal track caused by a contact of the magnetic tape 1 and the cylinder 4 are prevented or reduced.

Filed: 1987-01-09
Abstract: PURPOSE:To improve the plate thickness accuracy by changing over automatically from the plate thickness control by a rolling reduction amt. to that by a tension on detection of a roll kissing state. CONSTITUTION:The data of the plate thickness detector 4 at the rear part of a rolling mill 1 and data of a rolling load meter 6 are inputted to the roll kiss discriminating circuit 18 including a rolling reduction position arithmetic circuit and discriminating circuit and the roll kiss state is discriminated therein. The respective plate thickness control command value of an estimated plate thickness control circuit 10, gage meter type plate thickness control circuit 11 and monitor plate thickness control circuit 12 is added by an adder 13 and respectively operated in a rolling reduction converting circuit 14 and tension converting circuit 15. The control signal transmitted from the roll kiss discriminating circuit 18 is led to changing over circuits 16, 17 to carry out a plate thickness control by inputting a plate thickness control command as the rolling reduction amt. to the rolling reduction position control circuit 18 at a ordinary rolling time. And in the roll kiss state a tension plate thickness control is performed as a tension plate thickness control command by a speed control circuit 9. A very thin plate can thus be produced with high accuracy.

Title: Control method for internal combustion engine
Inventor: SHIMIZU KIYOSHI
IPC: F02D41/14
Filed: 1993-01-11
Abstract: PURPOSE:To control a fuel injection amount during rapid acceleration of an internal combustion engine to a proper value based on a combustion roughness value determined by an ion current method. CONSTITUTION:During rapid acceleration of an internal combustion engine at S52, a combustion roughness valve RN determined by an ion current method is read at S53. When the combustion roughness value RN exceeds a roughness reference value RNref and a combustion state is worsened at S54, a deviation DELTARN between the combustion roughness value RN and roughness reference value RNref is calculated at S55 and based on the deviation DELTARN, an increase- during-acceleration correction amount TACC is retrieved from a map at S56. By correcting a fuel injection amount based on the combustion roughness valve RN, there is no need to calculate the rate of adhesion of injection fuel to a wall surface and the rate of carriage away of fuel by a wall surface, and a control device is simplified.

Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To provide a Japanese language input system capable of converting the spelling input of an original language corresponding to a word of foreign origin into Japanese reading expressed by KATAKANA (square form of Japanese syllabary). SOLUTION: When the spelling of an English word is inputted from an input means 1, a conversion means 20 retrieves an original/KATAKANA conversion dictionary 51 and acquires the spelling of KATAKANA corresponding to the English word as a 1st candidate. An original/KATAKANA conversion rule 61 is applied to the spelling of a word of foreign origin not included in the dictionary 51. Namely the conversion means 20 refers to the rule 61 and acquires the spelling of KATAKANA corresponding to the spelling of the inputted English word as a 2nd candidate. A selection means 21 selects the 1st or 2nd candicate. Since both the conversion dictionary 51 and conversion rule 61 are used, the size of the conversion dictionary 51 can be prevented from being excessively increased.

Therefore, the amplitude can be increased as much as possible, and the measuring accuracy for the long distance can be improved. Since the point, where the reflected light is shielded and weakest, is detected, the problem of the dynamic range is not required to be considered.
