Title: Diaphragm for speaker
Inventor: HAYAKAWA FUMIO
IPC: H04R7/02
Filed: 1982-05-17
Abstract: PURPOSE:To obtain an excellent diaphragm, by providing a hollow spherical shell made of copolymer of a methylmethacrylate and acrylonitrile in the inside space of a paper layer body formed by a pulp fiber as a main material by a cation based binder in order to improve the diaphragm formed by paper layer. CONSTITUTION:A diaphragm for a speaker is constituted by a pulp fiber as its main material. The proper quantity of hollow spherical shells made of copolymer of a methylmethacrylate and acrylonitrile is included in the inside space of the paper layers made of the pulp fiber by a cation based binder. The apparent specific gravity of the hollow spherical shells constituting the diaphragm is made low by use of the copolymer of a methylmethacrylate and acrylonitrile. Due to the construction including the hollow spherical shells with the binder in the inside space of the paper layer body, the air permeability becomes excellent, the softening temperature of the diaphragm becomes high, the true specific gravity becomes low, and the chemical resistance becomes excellent.

Title: Alkaline battery
Inventor: YOSHIDA KAZUMASA
IPC: H01M4/06
Filed: 1980-06-20
Abstract: PURPOSE:To prevent any passive state of the negative electrode of an alkaline battery, and enhance the cold characteristics and the high-load characteristics of the battery by adding a macrocyclic complex compound such as crown ether to either the electrolyte or the negative electrode. CONSTITUTION:A molded mixture 2 containing either silver oxide or manganese dioxide as a positive active material is placed in a metal case 1, and a separator 3 and a nonwoven cloth 4 are placed over the mixture 2. After that, a gellike negative electrode 5 made of zinc, which is prepared by mixing zinc powder and a pasty material such as CMC with a caustic alkali electrolyte added with a macrocyclic complex compound such as crown ether or cryptate, is placed on the cloth 4, thereby an alkaline battery being constituted. Owing to the above constitution, any zinc- oxide film is not formed on the surface of zinc contained in the negative electrode, since zinc oxide ions generated during the discharge of the former zinc are incorporated in an electrostatic field developed in the center of the ring of the complex compound adhering to the surface of the former zinc, and are diffused according to host-guest reaction. Consequently, any passive state of the negative electrode can be prevented, and the cold characteristics of the battery can be greatly improved.

Title: Electrophotographic endless belt photoreceptor, and electrophotographic image forming method and device and photoreceptor cartridge using photoreceptor
Inventor: TAKEUCHI SHIGEKI
IPC: G03G21/00
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain an endless belt photoreceptor which does not cause faulty carrying or image defect by providing a joint part having a specified joint part angle and providing specified deflection at the longest part of a distance between rollers for laying. SOLUTION: When the joint of the endless belt passes a roller abutting part with the rotation of the endless belt at the time of forming an image, the joint part is made so as not to contact therewith over the entire length at a time, so that the carrying stability of the endless belt is improved. Therefore, by designing so that the joint angle may be >=1.0 deg. and further the deflection of the belt may be <=3 mm, the carrying stability of the endless belt photoreceptor is achieved. The size of the deflection at the end of the endless belt photoreceptor is adjusted to <=3 mm by somewhat deviating the peripheral length of the center part and the peripheral length of the end of the endless belt photoreceptor and making the peripheral length of the end shorter than that of the center part.  In a cartridge where the endless belt photoreceptor is stretched and laid, three rollers abut on the back surface of the belt photoreceptor and one roller abuts on the front surface thereof, and (c-d) is the longest length between the rollers.
