Title: Modification of polyethylene and reactive polyethylene
Inventor: CHO HATSUJO
IPC: C08L23/04
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To modify polyethylene for improving the affinity of a polyethylene base to a hydrophilic substance in a molded article composed of a mixture of the polyethylene base and the hydrophilic substance and improving the strength of the molded article by converting a polyethylene into a free radical and reacting it with an organic acid to improve the reaction activity. SOLUTION: A polyethylene such as a high-density polyethylene is converted into a free radical preferably by using benzoyl peroxide as a radical initiator and the product is reacted with an organic acid (preferably maleic anhydride) to obtain a modified polyethylene having improved reaction activity. The above reaction is carried out e.g. by adding the above organic acid and a solution obtained by dissolving the above radical initiator in a solvent such as acetone to the above polyethylene, thoroughly mixing the mixture and heating and maintaining the mixture preferably at about 150-160 deg.C. The obtained reactive polyethylene is added to conventional polyethylene at a ratio of preferably 0.1-100 wt.%.

Title: Health instrument for leg
Inventor: YOSHIMURA JIRO
IPC: A61H39/04
Filed: 1994-10-12
Abstract: PURPOSE: To provide the health instrument for leg which can be easily used over a wide age bracket. CONSTITUTION: A health instrument 1 is composed of a planar body equipped with arcuate recessed parts 11 at the respective sides of a rectangle. For example of using this health instrument 1, a user sits down on a chair, the health instrument 1 is standed in front of the chair, and ankles are put on the recessed parts 11. Pressure is generated between the health instrument 1 and the legs by the muscular strength of legs, bending the upper half part of the body forward and pushing down the crotch with lands or the like in the state of sitting down on the chair. A digital compression effect is generated by this pressure, and the blood circulation of legs is promoted. This instrument can be used in natural attitude and can be used by men and women of all ages even when the user is old or young or loses physical strength.  Since pressure can be adjusted by the user himself, a high effect can be provided by using this instrument corresponding to what the user likes naturally for long time while reading books.

Title: Maintenance method for stationary type nickel-hydrogen storage battery
Inventor: TADOKORO MIKIAKI
IPC: H01M10/42
Filed: 1993-09-06
Abstract: PURPOSE:To mitigate a drop of a capacity after maintenance and lengthen an interval of maintenance by setting an operating pressure of a valve for use in maintenance lower than an operating pressure of a safety valve during an electric charging/discharging cycle for the purpose of overcharging. CONSTITUTION:An operating pressure for use in maintenance is set lower than an operating pressure of a conventional valve, i.e., an operating pressure (3atm or higher) of a safety valve, more preferably set to 1.5-2.5atm, followed by overcharging (releasing overcharging). Although a battery capacity of the positive electrode, which is reduced after maintenance by the electric overcharging, is recovered from M2 to M1, an extra capacity S is generated in the negative electrode at the time of electric charging after maintenance. Consequently, electric charging is principally dependent on the positive electrode until hydrogen is completely stored in the extra capacity S. As a result, it is possible to mitigate a drop of the capacity after maintenance and lengthen an interval of maintenance.

Title: Image forming device
Inventor: SHIGETA KUNIO
IPC: G03G15/16
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To enhance the transfer ratio of a back surface toner image by electrifying the surface of a second image carrying means to the polarity identical to that of toner with the electrifying means of the second image carrying means arranged on the upstream side in the moving direction of the second image carrying means from a position where a transfer material enters the second image carrying means. SOLUTION: When a recording paper P is fed to a transfer area, the surface of a toner image receiving body 14a is electrified to the polarity identical to that of the toner by the electrifier 150 of the body 14a arranged on the upstream side in the moving direction of the body 14a from the position where the paper P enters the body 14a. Then, the paper P is made to enter so that it abuts on or approaches the surface of the electrified body 14a. The paper P is drawn near the body 14a by electric charge on the body 14a and attracted to the body 14a so as to be fed to the transfer area. Since the part of the paper P, where the back surface toner image exists and the part, where the back surface toner image does not exist, are electrified to almost mutually identical potential when the paper P is attracted to the body 14a, the back surface toner image is not scattered around. Besides, since the back surface toner image is electrified again, the transfer ratio with respect to the back surface of the paper P is enhanced.

Besides, a latch circuit 13 fetches the coincident address signal from a selector 12 at the fall of an ID signal, and outputs it as the detected address. Through this configuration, the address signal with an error is prevented from being propagated to plural storage means.

As a result, the sticking strength of the non-magnetic one component developing toner to an electrostatic charge carrying body is reduced and the power to binder the movement of the electrostatic toner is weakened. Then the central blanking is reduced and the high quality image is formed.

Title: Developing device
Inventor: HAYASHI KOJI
IPC: G03G15/08
Filed: 1989-09-22
Abstract: PURPOSE:To increase an electrostatic charge quantity up to an adequate value and to maintain the same by disposing an attaching/detaching member between a supplying section which supplies a developer to a developing roller and a regulating section which regulates the supplied developer and changing the attaching/detaching member to a 1st state or 2nd state, thereby controlling the increase of the electrostatic charge quantity of the developer. CONSTITUTION:The attaching/detaching member 109 is disposed between the supplying section which supplies the developer to the developing roller 101 and the regulating section 104 which regulates the supplied developer. The attaching/detaching member 109 is brought into contact with the supplied developer in the 1st state to rapidly increase the electrostatic charge quantity. The contact of the attaching/detaching member 109 and the developer is averted in the 2nd state to prevent the increase of the electrostatic charge quantity after the electrostatic charge quantity of the developer attains the adequate value. A control means 110 controls the change of the 1st state or the 2nd state to control the electrostatic charge quantity so as to prevent the excess increase thereof. The electrostatic charge quantity is rapidly increased up to the adequate value in this way when the electrostatic charge quantity is low. In addition, more than the necessary increase of the electrostatic charge quantity is prevented after the electrostatic charge quantity of the developer attains the adequate value.
