Filed: 1992-10-28
Abstract: PURPOSE:To develop a practical technique for predicting minor failures. CONSTITUTION:In an engine 1, sensor groups 2, 3, 4 are disposed of detecting pressure, flow and temperature of fluid flowing at respective portions. In a comparator 7, comparison is made between variation tendencies of detection values in the respective sensors and variation tendencies showing abmormalities agreement, abnormality at this position is determined, so that a prediction signal S is outputted from an output device 8. Accordingly, signs of various minor failures, possibly leading to a major failure or accident if left alone, are predicted, in am early stage. Necessary steps are thus taken in advance, thereby preventing occurrence of a major failure or accident.

Title: Magnet plate for part feeder
Inventor: SAITO KOJI
IPC: B65G47/14
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a part feeder magnet plate which is useful for transferring a part well. SOLUTION: A magnet plate 6b is mounted on a guide block 6a, and a part P transferred by a belt 7 is attracted by the magnetic force of a magnet M1 of the magnet plate 6b to come into close contact with the surface of the belt 7, whereby the part P is surely prevented from being levitated or tilted. Moreover, no magnet is provided at a part outlet under a part transfer region of the belt 7, so that the part P is not prevented from being led onto the belt 7 from a vertical passage 5b and from being turned over by the magnetic force of the magnet M with the movement of the belt 7. The magnet plate 6b is mounted on the guide block 6a in a detachable manner, so that part P of different size can be surely brought into close contact with the surface of the belt 7 the same as above by replacing the magnet plate 6b with a proper one.

Title: Uniform velocity joint
Inventor: KURA HISAAKI
IPC: F16D3/2245
Filed: 1989-11-30
Abstract: PURPOSE:To eliminate play in a joint by providing ball guide tracks formed on the inner surface of the outer ring and on the outer surface of the inner ring with mixedly located angular contacts (AC) tracks and circular contacts (CC) tracks and giving a preload onto the CC tracks. CONSTITUTION:AC tracks and CC tracks are formed by turns in the circumferencial direction at positions on the inner surface of the outer ring 1 and on the opposite positions on the outer surface of the inner ring 2, with a torque transmission ball 4 fit in each of the AC and CC tracks. If a preload is given to both AC and CC tracks, friction increases in the AC track because of four point contacts, resulting in adverse effect of temperature rise, etc. If the preload is given to the CC track only, play in the joint is eliminated and the AC and CC tracks are in contact at two points. As a result, the balls 4 roll correctly to transmit torque, characteristics of temperature rise prevention, durability, allowable revolution, and NVH performance are improved.

Abstract: PROBLEM TO BE SOLVED: To provide an on-snow bicycle which does not spoil ski-feeling on the snow and is excellent in traveling performance. SOLUTION: A sled plate 2 is fitted in place of a front wheel of a bicycle, and a wheel-shaped sled 3 is fitted in place of a rear wheel. The wheel-shaped sled 3 is of the structure where a plurality of sleds of the same shape are arranged in a circumference, and when not in rotation, the wheel-shaped sled plays a role similar to that of a regular sled plate. When in rotation, a V-shaped rear part 6 is bitten in snow, and pushes the snow backward to obtain the propulsion. A gear 7 is fixed to an axle of the wheel-shaped sled 3 to agree the rotational direction of a pedal with the rotational direction of the wheel- shaped sled 3. The propulsion is obtained by stepping on the pedal. After the advancing speed is obtained, the pedal is stopped, and the skiing on the snow can be enjoyed with the wheel-shaped sled 3 forming a regular sled.

Filed: 1993-12-15
Abstract: PURPOSE:To provide the accumulator type fuel injection device without multi- cylinder interference, which is high in strength, and easy to be mounted, being manufactured without bending and forming of high pressure piping. CONSTITUTION:An injector 2 provided for each cylinder of an engine 1 and a high pressure pump 7 are connected to each other by an accumulator container 30 formed out of a single member.

Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To enable even a user who is not familiar with double Pinyin to obtain a conversion result by performing correct input a double Pinyin. SOLUTION: When a correspondence relation display indication key 21b is pressed while a character string is being inputted from an input part 21 while a double Pinyin input mode is set, a control part 22 actuates a Pinyin correspondence reference process part 25 to extract a double Pinyin character string which can be inputted successively to the input character string and a Pinyin character string corresponding to it from a key array table 26. These character strings are presented to the user through an output part 28. Consequently, even if the user becomes usable to find the key array of double Pinyin in the input operation, the user can correctly input the character string which should be inputted after confirming the character string together with the Pinyin character string and obtain desired Chinese characters as the conversion result.
