Title: Developer for negative charge latent image
Inventor: MATSUBARA AKITOSHI
IPC: G03G9/087
Filed: 1987-05-15
Abstract: PURPOSE:To highly stabilize the triboelectrostatic chargeability of a toner and to improve moisture resistance, durability, etc., by incorporating specific elements into a required two-component type developer. CONSTITUTION:The two-component developer is formed of a coated carrier to prevent the adhesion of liberated toner slag and the adhesion of the fine particles added to the toner and a nonmagnetic toner. Positive chargeable fine silica particles subjected to a surface treatment are incorporated into this developer to impact the stable and high positive triboelectrostatic chargeability to the toner, by which the moisture resistance is improved. In addition, the flowability of the developer is enhanced and the resistance to flawing is imparted to a photosensitive body. Fluorine polymer particles are incorporated therein as well so that the triboelectrostatic chargeability is additionally enhanced and the fluctuations in electrostatic charge are decreased even after long-term use. The durability is thereby improved and further, the generation of flawing of a cleaning blade and staining of the surface of the photosensitive body is prevented. The triboelectrostatic chargeability of the toner is, therefore, highly stabilized and various characteristics including the moisture resistance, durability, etc., are enhanced. The developer which is capable of forming the high-quality image is thus obtd.

Title: Compact container
Inventor: TORII AKIHITO
IPC: A45D33/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a compact container capable of securing the smoothness of a mirror and reducing its weight. SOLUTION: A mirror 20 is supported on the bottom surface of a lid 10 with the three points of projections 13 to 15. Thus the mirror is not deformed but only tilted even when the projections 13 to 15 are curved by deforming of the lid 10 due to arching, etc. Thus, since the smoothness of the mirror 20 can be secured, an object can be reflected without deforming. Consequently, since deformation is not generated in the mirror 20 even when the thickness of the mirror 20 is reduced, the thin mirror 20 reduced in its weight can be used.

Abstract: PURPOSE:To contrive to reduce costs and miniaturize by a method wherein electronic components containing inductor elements are provided in a compartment partitioned by a sealed board of a printed panel, and the electronic components and/or the sealed board adjacent thereto are inclined to adjust a frequency characteristic. CONSTITUTION:A band-pass filter 10 is mounted inside a compartment 6a, and necessary circuits for a TV tuner 1 excluding the band-pass filter 10, such as a high frequency amplifying circuit, a mixture circuit, a local transmitting circuit or the like, are arranged in a compartment 6b. When the band-pass filter 10 is being inclined to the side of a sealed portion 5a, the larger the inclination becomes, the higher the central frequency becomes. Accordingly, if a separate distance is specified so as to set to a desired central frequency by inclining the band-pass filter 10, it becomes possible to adjust a frequency. With the above arrangement, frequency adjusting members can be made unnecessary, it can be contrived to reduce costs, and electronic components themselves can be miniaturized by omitting a sealed case.
