Title: Bottom-scooping bucket
Inventor: INOUE HACHIRO
IPC: E02D5/44
Filed: 1986-08-25
Abstract: PURPOSE:To completely remove out slime in a pit with an expanded portion under the ground by a method in which a bucket is landed on the bottom of a pit under the ground, and an opening and closing scraper provided to the side of the bucket body is opened outwards by rotating force. CONSTITUTION:A pit 34 is excavated in the ground, and a bucket body 1 attached to the lower end of a Kelly-bar 35 is inserted into the pit 34. In this case, an opening and closing scraper 2 does not open by the weight of the bucket 1 because a notched portion 13 is coupled with a projection 14. When the bucket 1 is landed on slime 38 and is slightly raised in relation to the bar 35, the link 16 is freed by releasing the coupling of the notched portion 13 and the projection 14. Under the condition, when the bar 35 is turned oppositely, the scraper 2 is opened at the shaft 20 and slime 38 in the expanded portion is raked into the bucket. Slime in the pit 34 with expanded portion can thus be completely discharged.

IPC: H01F13/00
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To magnetize a magnetic material, so that a plurality of magnetic poles are formed evenly at fine pitches near its endless peripheral surface and, at the same time, to form an appropriate residual magnetization pattern only in a region where magnetization is required without causing residual magnetization in a region where no magnetization is required. SOLUTION: A material 2 to be magnetized having a cylindrical peripheral surface is supported, so that the material 2 can be rotated around its center axis and a magnetized head 3 is brought closer to or into contact with the peripheral surface of the material 2. Then the peripheral surface of the material 2 is spirally magnetized by rotating the material 2 and moving the head 3 in the axial direction of the material 2. After nearly the entire region of the peripheral surface of the material 2 has been magnetized, both end sections are demagnetized in a direction nearly perpendicular to the axial direction of the material 2. For the demagnetization, the same head 3 is used and an electric current having a frequency higher than the current used for the magnetization has is supplied to the excitation coil 10 of the head 3.  The magnetized region can be made nearly perpendicular to the axial direction of the material 2, by performing the magnetization by stopping the movement of the head 3 in the axial direction, while the material 2 makes one round at the starting time and ending time of the magnetization.

Abstract: PROBLEM TO BE SOLVED: To remove the eccentricity of a recording disk and to suppress vibrations at the time of rotation by adjusting the geometrical center of the recording disk set in a stopping state so as to minimize the vibrations in a rotating state. SOLUTION: A master resist disk 14 is placed on a turntable without being adsorbed, a micrometer 21 and a distance sensor 22 are contacted to an end face and the turned table is rotated at 90 deg. every time. Each time the turntable is rotated at 90 deg., a distance detecting signal is outputted from the distance sensor 22 to a personal computer(PC) 11, the master resist disk 14 is controlled so as to be moved by the micrometer 21 with encoder while minimizing the difference of respective values, and the geometrical center of the master resist disk 14 is set. Thus, the master resist disk 14 is adsorbed to the turntable and rotated at fixed low speed. The vibration caused by the circularity deviation of the master resist disk 14 is detected by a vibration sensor 23 and the vibration detecting signal is outputted to the PC 11.  The PC 11 releases the adsorption again so as to minimize the detected vibration and repeatedly moves the master resist disk 14 little by little with the micrometer 21.

Title: Image forming device
Inventor: HANDA OSAMU
IPC: B41J2/525
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a superior transcription image all the time independent to environment without using a special environment detection means and a control means, by switching a constant-current control mechanism to/from a constant-voltage control mechanism according to resistance values of a transcription means. SOLUTION: An electrification apparatus 12, an exposure unit 20, a black toner and colored toner developing counter 30, a primary transcription unit (roll)15, a cleaner 16, and an electricity eliminating lamp 17 are arranged around the circumference of a photosensitive drum and a toner image is formed on the photosensitive drum 10 surface. When the resistance of the transcription roll 15 is high (low-temperature and low-humidity environment), a constant current value is secured by the constant- current control. When the resistance of the transcription roll 15 is decreased (high- temperature and high-humidity environment) and if the temperature and the humidity are increased and the resistance of transcription roll 15 is decreased the voltage necessary for flowing a prescribed current value is decreased.  When this voltage is decreased to a prescribed voltage, the constant current control is switched to the constant voltage control. The current is increased by the constant voltage control. As the resistance of the transcription roll 15 is decreased, the flowing current value is thus increased.
