Title: Plasticized polyetherimide adhesive composition and its use
Inventor: JIYON HENRII RUPINSUKI
IPC: H01L23/10
Filed: 1993-12-08
Abstract: PURPOSE: To obtain an adhesive composition which realizes void-free adhesive bonding between a substrate provided with a temperature-sensitive IC chip and an overlay dielectric layer at a low temperature in a high-density interconnect circuit array.  
     CONSTITUTION: A plasticized polyetherimide adhesive composition (40) is formed from 100 pts.wt. polyetherimide and 5-25 pts.wt. plasticizer. This composition (40) can have melt viscosity capable of providing a void-free adhesive bonding 40 between a substrate 10 provided with an IC chip 30 and an overlay dielectric layer 50 at a temperature in the range of about 200-260°C. Even when the IC chip is made from e.g. GaAs which deteriorates in performances at 300°C or above, it can avoid temperature influence at the stage of the above adhesive bonding.

Title: Opening/closing timing calculation method for intake/ exhaust valve
Inventor: FUJII KOJI
IPC: F01L1/34
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To eliminate an influence of an engine rotation angular velocity change from a calculated opening/closing timing, reduce an error of a real value, and ensure the safety operation by calculating the opening/closing timing from the control state of a variable valve timing mechanism, when the engine rotation speed is low. SOLUTION: In operating an engine, an electronic controller 24 judges whether the engine rotation speed is a prescribed low rotation speed or less or not and when it is less than that, the opening/closing timing and a target opening/closing timing are set to 0. On the other hand, when the engine rotation speed is a prescribed high rotation speed or more, a real phase difference between an intake cam signal (d) and an exhaust cam signal (b) is calculated from a time difference between the both signals (d), (b) according to cylinders and the engine rotation speed.  The target opening/ closing timing is set by such a function (f) that the difference between the most delay angle learning value, which is the phase difference between the intake can signal d0 and the exhaust cam signal (b) under a most delay angle state learned and stored beforehand, and the real phase is set to the opening/closing timing and the engine rotation speed and the intake pipe pressure are set to parameters.

Title: Pad wear automatic adjustment mechanism for reverse disk brake device
Inventor: HONMA AKIRA
IPC: F16D55/224
Filed: 1990-11-13
Abstract: PURPOSE:To adjust automatically the position of a carrier along with wear of a pad by providing an adjust bolt screwed in a housing fixed to a carrier, a flange between a cam and the adjust bolt and a one-way clutch to regulate the rotation of a push rod and the adjust bolt in a direction getting away from a disk. CONSTITUTION:In the state of the brake being released, a push rod 11 touches a true circle portion C and the tip of an adjust bolt 12 touches the rear end of the rod. Under this condition, a flange 13 is away from the tapered surface of the bolt tip, so that due to a one-way clutch 14 the rotation of the bolt 12 is permitted. A carrier 2, 3 thus approaches toward a disk while rotating the bolt 12 until a pad constantly touches the disk at a specified pressure. In rotating a cam 6 with a lever 7, a flange 13 is pushed by cam surfaces (a, b) so that it retreats and touches the bolt 12. The clutch 14 is then applied, so that the rotation of the bolt 12 is prevented and the carrier 2, 3 is pushed open due to the pushing force of the cam. Consequently, the clearance is automatically adjusted to a specific dimension.

Title: Levitation using centrifugal force and power generation device
Inventor: FUJIMOTO HIROSHI
IPC: F03H99/00
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To reduce ground friction and a noise of a traveling vehicle by floating a device by an anti-gravitational property generated by weights to rise by centrifugal force by rotation. SOLUTION: Weights 7 and 7' made movable by being placed on horizontal guiding frames 6 and 6' fixed to a bottom part of a central shaft 1 and the central shaft 1 are connected to each other by wires 11 and 11' or the like. Outward proceeding force is generated in the weights 7 and 7' by centrifugal force generated when the weights 7 and 7' rotate by rotation of the guiding frames 6 and 6' by rotation of the central shaft 1, and the wires 11 and 11' become horizontal, and the weights 7 and 7' fly in the air. When mass of the weights 7 and 7' is set equal to weight of a device and the other load total or not less than that, a part of (14) can be raised up to a position of (15) at rising time of the device itself.  In this way, since the centrifugal force increases as weight of the weights and rotating speed increase, when the mass of the weights and the rotating speed are increasingly adjusted, an anti-gravitational property in the air can be increased.
