Title: Control device of movable body driven by motor
Inventor: AKAIWA EIJI
IPC: H02P29/00
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To prevent a state where a device cannot be controlled and at the same time prevent a motor power amplifier from being burnt or the like, by calculating the out of a motor from the angular velocity and the armature current of the motor, and controlling the output of the motor so that it is constantly equal to or less than the maximum output. SOLUTION: A first angular velocity limiter 18a calculates the output of a motor 3 from the angular velocity of the motor 3 being outputted from a first angular velocity detector 8a and an armature current being outputted from a first current detector 9a. When the operation result exceeds the maximum output of the motor 3, the maximum angular velocity that is allowed for the motor 3 is calculated and the angular velocity is limited based on the result, thus preventing the output of the motor 3 from exceeding the maximum output. A second angular velocity limiter 18b also operates similarly as the first angular velocity limiter 18a, thus ensuring the stability and safety of the control device of a movable body that is driven by the motor.

Title: Piston ring and its manufacture
Inventor: ONODERA YOSHIO
IPC: C23C8/26
Filed: 1989-12-29
Abstract: PURPOSE:To prevent crack of a nitride layer and improve its wear resistance by constituting the nitride layer which is formed on the surface of a piston ring by a low temperature nitride layer due to low temperature nitriding and high temperature nitride layer due to high temperature nitriding. CONSTITUTION:After low temperature nitriding is applied on the surface of a compression ring base material 31 made of steel, high temperature nitriding is applied. Then, at least porous layer on a slidingface 33 is removed to expose a diffusion layer. Thus, a nitride layer 32 is composed of a low temperature nitride layer and a high temperature nitride layer. As a result, a first diffusion layer 34 is formed outward, and a second diffusion layer 35 is formed in the inside of the first diffusion layer 34. The above-mentioned porous layer is a fragile layer which is called white layer. The product is produced by removing the porous layer on the whole surface including the slidingface 33 and exposing the diffusion layers 34, 35. Thus the produced product does not cause crack of nitride layer as a result of durability test by using an actual machine. Also, the amount of wear is less than or equivalent to that of conventional products.
