Title: Fixing device and image forming device
Inventor: OTA HIROSHI
IPC: G03G15/20
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To obtain a long-lived oil supplying means, without causing a defect in an image such as the run and smear of oil by providing a gap part for housing the oil inside the oil supplying means. SOLUTION: A cleaning roller 5 is constituted of a ceramic layer 12 impregnated with the oil in pores, a shaft 11 inserted through the central part of the ceramic layer 12 and a felt layer 13 for covering the ceramic layer 12. The gap part 14 as an oil supply adjusting means is formed between the shaft 11 and the ceramic layer 12. While rotating in a direction opposite to that of the rotation of a heating roller, the cleaning roller 5 discharges the oil from the ceramic layer 12, to supply the oil to the heating roller through the felt layer 13. When the outside diameter of the cleaning roller 5 is made larger, the oil is discharged from the ceramic layer 12, because of initial stage thermal expansion.  At this time, the gap part 14 is formed in the ceramic layer 12, so that the oil discharged because of the thermal expansion is discharged toward the gap part 14 whose resistance is low as well. Thus, the quantity of the oil discharged to the side of the felt layer 13 is suppressed.

Title: Manufacturing method of collector of lead storage battery
Inventor: ISHIKURA YOSHIKAZU
IPC: H01M4/75
Filed: 1978-12-07
Abstract: PURPOSE:To improve the corrosion resistance of a collector by anode-oxidizing a collector made of a lead alloy in a sulfuric acid solution containing phosphoric acid ions to form a lead dioxide film over the surface of the collector. CONSTITUTION:A solution is prepared by mixing 0.5-1.5wt% ortho-phosphoric acid in a sulfuric acid solution of 1.20-1.35 specific weight. A collector, such as a grid or core, made of lead or a lead alloy is immersed in the solution and connected to the positive terminal to subject to anode-oxidizing for 1-6 hours with 0.5- 3A/dm<2> current density. The phosphoric acid ions suppresses the three dimensional growth of lead dioxide crystals on the surface of the grid during the anode-oxidizing of the grid and promotes the formation of two-dimensional minute layer of lead dioxide over the surface of the grid. The layer of lead dioxide thus formed is corrosion resistant and preventive to development of corrosion into the grid structure and improves the electrical and mechanical cohesion of an active material to the grid.

Title: Device for observing magnetization state of magnetic material
Inventor: DAIROKU NORIYUKI
IPC: G01R33/032
Filed: 1987-06-23
Abstract: PURPOSE: To enable the observation of a magnetization state with high image quality by changing the relative angle of polarization of a polarizer and analyzer and subjecting the images picked up before and after the change to an arithmetic processing.  
     CONSTITUTION: The light from a light source 1 is projected via the polarizer 2, a translucent mirror 6 and a lens 7 on a magnetic transfer body 8. The magnetization state of a magnetic recording medium 9 is transferred to this transfer body 8. The plane of polarization of the reflected light is rotated in a positive or negative direction by the magnetization direction of the transfer body 8. The image formed 11 through the analyzer 10 is detected in the following manner: The part having the magnetization direction where the plane of polarization is rotated positive is bright and the part negative is dark. The output signal of an image pickup element 11 is then stored 12. The formed 11 image is reversed in various densities from the image picked up before the rotation of the polarizer 2 and is stored 13 when the polarizer 2 is rotated at a prescribed angle by a motor 5. These two images are subjected to the subtraction processing by an arithmetic processing circuit 14 and are outputted to an output device 15. The magnetization state of the magnetic material is thus observed with the high- quality image.

Title: Non-contact type groove sensor
Inventor: FUKUI KIYOUJI
IPC: B23K9/12
Filed: 1978-12-12
Abstract: PURPOSE: To detect even a narrow groove at high precision, by eliminating electromagnetic mutual interference of the detecting coil of captioned sensor.  
     CONSTITUTION: AC power supplies 3, 4 differing in frequency are connected to detection coils 11, 21 of a sensor S which is integral with welding torches set parallel on a plane vertical to, for example, work W face WS and groove line WL. Both the coils 11, 21 change in the value of Q due to the effect of work W, and the balance is broken in both bridges B 1 , B 2 , and output signals are issued. These signals are passed through amplifiers 5, 6 and filter circuits 7, 8, and only 1 and 1.3MHz signals are taken out and are inputted into an amplifier 30 through rectifying circuits 9, 10. When distances l 1 , l 2  between groove line WL and coil center line LC, and IC and 2C are not equal to each other respectively, it results in 1P≠2P, and the outputs in the circuits 9, 10 vary, so that the output value of the amplifier 30 is no longer zero. Thus, depending whether the output is positive or negative, the deviation direction with respect to the sensor S and groove line WL is  judged.

Title: Device for clamping stator coil
Inventor: HARUTA TAKASHI
IPC: H02K3/50
Filed: 1977-12-23
Abstract: PURPOSE: To eliminate gap between a spacer and a stator coil and to restrict the extension and contraction of the coil by fixedly interposing a cylindrical spacer of large elastic surface frictional resistance between the ends of windings adjacent to the stator coil.  
     CONSTITUTION: An elastic cylindrical space 3P of parallelogram in section is interposed between the ends 2 of stator windings and mounted by a binding wire 4 to clamp the ends 2 of the windings. If only one winding end 2a is thus extended due to the unbalance or the like of cooling, the spacer not initially making contact with  the end of the winding makes at the outer surface thereof contact with the end of  the winding to become resistant surface so as to restrict the extension and contraction of the ends of the windings. Since the spacer 3P has elasticity, no gap occurs  between the spacer and the end of the winding due to the vibration of an electric machine.

Title: Method and device for estimating characteristic of optical fiber
Inventor: HORIGUCHI TSUNEO
IPC: G02B6/00
Filed: 1988-06-24
Abstract: PURPOSE:To measure the characteristic distribution of an optical fiber with high accuracy by utilizing the amplification of Brillouin light between 1st and 2nd signal light which opposingly propagates in the optical fiber and analyzing the waveform of the 2nd signal light which receives the effect of said amplification. CONSTITUTION:The pulse-like signal light S1 (light frequency f1) projected from a light source 1 is connected to the terminal 3-1 of the optical fiber to be measured 3 through a multiplexer/demultiplexer 4. The signal light S2 (light frequency f2) projected from a light source 2 for CW oscillation is connected to the terminal 3-2. At such a time, the amplification of Brillouin light is performed with the light S2 and S1 by controlling 7 so as to obtain f1-f2=fB (fB is a Brillouin shift frequency peculiar to the optical fiber 3). A signal processor 6 receives the electrical signal of the light S2 detected by a photodetector 5 and analyzes the temporal waveform of said signal to obtain the light loss of the fiber 3 from the attenuation factor of the component amplified with the light amplification or the level difference of light receiving signal on an optional point. If the light power of the light source 2 is increased, the level of the light receiving signal can be increased.

Title: Apparatus for bundling with wire
Inventor: YOSHIDA TOSHIO
IPC: B23K101/14
Filed: 1987-06-22
Abstract: PURPOSE:To continuously perform a wire winding and cutting operation by cutting a wire at its twisted portion moving the wire toward an object to be bundled on a wire winding stand while rotatably twisting both ends of the wire after gripping both ends thereof by a wire fixing means of a wire winding member. CONSTITUTION:Upon feeding of wire 80 in predetermined size to a wire winding member 40 by a wire supply member 20, an object 90to be bundled undergoes a uniform tightening force by the wire 80 from both sides thereof, since the wire 80 is wound around the object 90 by rotating both arms 41 after a desired tension is applied to the wire, concurrently with both ends thereof gripped by a wire fixing means 42 provided at the end of the wire winding member 40. In a bundling operation with the wire 80, after gripping both ends of the wire by clamp portions of a wire twisting member 60, a twist portion of the wire is formed, while rotating the clamp portions with a constant tension applied to the wire 80 and, at the same time, the wire is cut using a twist-off force which is caused by the local concentration of a force on the twist portion due to a shrinkage in the length of wire between the clamp portions resulting from the formation of the twist portion, without any extra extra cutting tools being used.
