Title: Screw fluid machinery
Inventor: KAMETANI HIROCHIKA
IPC: F04C18/08
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To drive a screw fluid machinery quietly in an extensive driving range by preventing tooth surface separating vibration peculiar to the screw fluid machinery. SOLUTION: A male rotor 1 and a female rotor 2 are engaged with each other and rotate on a screw fluid machinery. Teeth formed on an outer peripheral part of each of the rotors are twisted in the axial direction. These rotors are stored in a casing, and a compression working chamber is formed between a casing inwall surface and outer peripheral surfaces of the both rotors. Most of the teeth of the male rotor are formed on the outside of a pitch circle and most of the teeth of the female rotor are formed on the inside of the pitch circle. The male rotor and the female rotor make contact with each other or approach most to each other at one to three points.  Rotor shapes at positions where the rotors make contact with or approach to each other at the one point on the advancing surface side and the two points on the retreating surface side are specified so that a rotating radius RL of the female rotor at a contact point 5 on the advancing surface side becomes smaller than a rotating radius RT of a contact point 6 nearer to a rotating center of the female rotor of the contact points on the retreating surface side.

Filed: 1992-12-09
Abstract: PURPOSE:To obtain a metal surface treating agent for increasing adhesion between a metal surface and a resin board by combining specific epoxy silane compound and specific bistrialkoxysily compound. CONSTITUTION:Metal surface treating agent is a combination of 3- glycidoxypropylsilane compound A represented by a formula I and bistrialkoxysilyl compound B represented by a formula, (R<3>O)3SiR<4>Si(R<3>O)3, as effective constituents, wherein R<3>O denotes a lower alkoxyl group where the number of carbon atoms is 1 to 4, and R<4> indicates an alkylene group whose number of carbon atoms is 1 to 8. In the formula I, R<1> and R<2> are an alkyl group where the number of carbon atoms is 1 to 3, and n denotes an integer of 1 to 3. The metal surface treating agent of this design can be used independent of kinds of metal. For instance, the agent can be applied as a metal surface treating agent for copper, zinc, and alloy of them. It is optimal that the agent is applied to copper, and when the agent is applied to a copper foil used for a printed circuit copper plated laminated board, it becomes most effective.

Title: Fuel controller of internal combustion engine
Inventor: KATO AKIRA
IPC: B01D53/94
Filed: 1993-12-01
Abstract: PURPOSE:To improve an exhaust gas emission characteristic in any conditions of a catalytic converter by controlling air fuel ratio so that the purification factor of the catalytic converter is maximized. CONSTITUTION:A fuel controller of internal combustion engine is formed to operate a process 3 for estimating the maximum oxygen accumulation level OMAX of a catalytic converter, a process 6 for estimating the oxygen accumulation level O2STR of the catalytic converter, a process 7 for calculating an oxygen utilization factor 2USER, and a process 8 for perturbing an air fuel ratio A/F. The purification factor of the catalytic converter can be increased, in particular, by vibrating the oxygen accumulation level O2STR at a large as possible amplitude in the range from zero to the maximum oxygen accumulation level OMAX, by employing air fuel ratio control so that the oxygen utilization factor O2USER is maximized. The value of the oxygen utilization factor O2USER is subtracted when the oxygen accumulation level O2STR exceeds the maximum oxygen accumulation level OMAX, or when the O2STR is less than zero, since no exhaust gas is purified in these occasions.

Filed: 1990-11-28
Abstract: PURPOSE:To speed up a phrase segmenting process by regarding a specific HIRAGANA (cursive form of Japanese syllabary) as one phrase and correcting a phrase break insertion position when the specific HIRAGANA character string is present in a sentence inserted at the break between phrases. CONSTITUTION:When a unit of segmentation is extracted from a document stored in a document storage means 1, a character kind decision means 4 decides the kinds of characters constituting the sentence and the decision results are replaced with either of two kinds of code and stored in a decision result storage means 6 in order. Then a phrase segmenting means 7 puts a phrase break in the readout sentence when detecting a predetermined code change point. Then a phrase segmentation correcting means 9 compares an input character string with prescribed HIRAGANA characters in a specific character dictionary means 8 by tracing back the sentence from the break between the phrases, recognize a matching HIRAGANA character as one phrase, and corrects and outputs the phrase segmentation position. Consequently, language processing can be performed after the phrase position is detected, so the processing time can greatly be shortened.
