IPC: F16F15/31
Filed: 1983-02-22
Abstract: PURPOSE:To improve the acceleration characteristic of a rotor, by setting up a weight shiftably in the peripheral direction of a rotor shaft. CONSTITUTION:A linear rod 3 is projectingly installed in a rotary shaft 1, and an arcuate rod 4 centering a shaft center of the rotary shaft 1 is projectingly installed in a middle part of the linear rod 3, then a first weight 5 is slidably fitted in the linear rod 3, while a second weight 8 is slidably fitted in the arcuate rod 4, and these first and second weights 5 and 8 are coupled together through a rope 9. When a rotor is driven and the shaft 1 gets rotating, the weight 8 fails to follow up the acceleration of the shaft 1 whereby the weight 8 slides on the arcuate rod 4 in a B direction, therefore the first weight 5 also slides in a C direction therewith. With this constitution, the first weight 5 makes a distance from the shaft center shorter according to rotative accelertion of the shaft 1, and inertial mass in the whole flywheel device is made to be smaller so that the acceleration characteristic of the rotor is improved.

Title: Hand scanner
Inventor: HOZUMI YASUSHI
IPC: G06K7/016
Filed: 1980-03-06
Abstract: PURPOSE:To enable to perform the manual scanning, by detecting the subscanning speed of original and obtaining the synchronizing signal. CONSTITUTION:The scanner 1 is manually operated on the read-in scanning objective (original, etc.) 7. The wheel 2 for detecting subscanning speed detects this subscanning speed. The pulse produced in response to the speed is multiplied by in- creasing the scanning density. This signal is used as the pulse to start the main scanning of the photoelectric conversion element 9. Thus, the photoelectric conversion element 9 can read in response to the read-in speed of the scanner 1. Since the scanner 1 can be held in hand and scanned on any object, it can be used for the read-in of stecker on package or the like.

Title: Magnetic flux density change detector
Inventor: WAKAI KIYOSHI
IPC: G01D5/245
Filed: 1985-02-16
Abstract: PURPOSE:To detect the displacement or the rotation of a subject to be inspected precisely by arranging two magnetoelectric elements electrically connected each other on a surface opposed to the subject in a direction intersecting orthogonally with the direction of magnetic flux density change. CONSTITUTION:Two pairs of magneto-resistance effect (MR) elements 2a, 2b, 3a, 3b are arranged in the direction of magnetic flux density change due to the rotation of a rotor 12, i.e. in the axial direction intersecting orthogonally with the tangential direction of a rotor 15. The interval between one MR elements 2a, 2b and the other MR elements 3a, 3b is lambda/4 bit. Since pole teeth 19a, 19b are shifted by a half pitch each other, the phases of a pair of MR elements 2a, 2b have a phase difference of lambda/2. Thereby, these MR elements 2a, 2b, 3a, 3b have similar phase differences. Since a bias permanent magnet 20 is built in the inside of a substrate 4, respective signals are detected with a high level corresponding to the bias.

IPC: F01D5/28
Filed: 1987-02-13
Abstract: PURPOSE:To improve erosion resistance of a turbine blade without generating any deformation and residual stress in the turbine blade by forming a surface hardened layer on the steam-inlet side of the tip of the turbine blade by means of chrome plating using oxalic acid. CONSTITUTION:A turbine blade 2 is rotatably fixed to a rotor at a blade root 3, and an erosion preventing means 1 is provided on the stem-inlet side of a tip to prevent erosion. In this case, a surface hardened layer formed by chrome plating using oxalic acid is employed as the erosion preventing means 1. For the surface hardened layer, the hardness is set at Hv1,000 or more, and the thickness is set at 100mum or more, respectively. Thus, the surface hardened layer can be formed without generating any deformation in the turbine blade 2. And, since welding is not employed, the generation of residual stress due to correction of welding deformation can be prevented. Further, erosion resistance can be improved because of high hardness of the surface hardened layer.
