Title: Synthetic resin pallet
Inventor: MIYATA KAZUHIKO
IPC: B65D19/32
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To reduce the shrink difference between the rib and the deckboard in the cooling process of half-split pallets after injection molding, by forming a thick part at a part of the underface of the deckboard surrounded by the ribs extended down to the underface of the deckboard. SOLUTION: The deckboard 10 is made thin for a light-weight synthetic resin pallet. The thickness of the ribs 50 extended down to the underface of the thin deckboard 10 is formed thicker than the deckboard 10. The thick area h1 of the deckboard 10 formed at the underface of the deckboard 10 surrounded by longitudinally and laterally extending ribs 50 is made smaller than the underface area of the square deckboard 10 surrounded by the longitudinally and laterally extending ribs 50 and made to have a nearly similar square to the underface area of the deckboard 10. In this way, the shrink difference of the ribs and the deckboard is reduced in the cooling process of the half-split pallets after injection molding. And bending of the deckboard to the upward side and forming of shrink marks on the surface can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of density unevenness such as a fogging and a halftone over the whole area of a transfer material used in an image forming device, without increasing the scale of the device. SOLUTION: A developer is supplied to the outer peripheral of a developer carrier 1 by a supplying member 3, regulated to a fixed layer thickness by a layer thickness regulating member 4 and then, carried toward a developing area 5 in the direction of arrow K2, while being held by the magnetic force of carrying poles 7 and 8, on the developer carrier 1. In the developing area 5, development with a low charged developer is suppressed by the magnetic force of a developing pole 9, to attain proper development processing. At this time, the magnetic pole width of the developing pole 9 is set to be larger than those of the carrying poles 7 and 8, to prevent the occurrence of the density unevenness such as the fog and halftone over the whole area of an image forming area width corresponding to the magnetic pole width of the carrying poles 7 and 8.  Further, it is unnecessary that the magnetic pole width (=image forming area width) of the carrying poles 7 and 8 are provided, so that the increase of the scale of a developing device 20 can be evaded.

IPC: H01L21/3065
Filed: 1983-03-31
Abstract: PURPOSE:To form the surface of insulators flatly by forming an insulator of a minimum etching rate to a lowermost layer in a formed groove, shaping insulators in succession in order of larger etching rates and forming the insulator of the minimum etching rate to an uppermost layer. CONSTITUTION:When a U-shaped groove 2 is buried with insulators, an insulator 3(1) of a minimum etching rate is formed first. Insulators 3(2), 3(3), 3(4) are formed in succession in order of larger etching rates, and the insulator 3(1) of the minimum etching rate is shaped to an uppermost layer. When the uppermost layer 3(1) is etched through whole-surface etching using an etching liquid of hydrofluoric acid, the central section of the insulator 3(1) remains because the thickness of the insulator 3(1) is large at the center. When the etching is continued and the insulator 3(4) positioned on the peripheral section of a substrate is removed, the insulator 3(1) also remains on the central section of the groove together with the insulator 3(4), the insulators on the central section of the groove is upward projected slightly in the state in the case when the insulator 3(1) of the lowermost layer is removed, and the edges of the groove 2 is covered with the insulator 3(1). Accordingly, the permeation of the etching liquid is prevented sufficiently.

Abstract: PURPOSE:To sharply improve the efficiency of proofreading work for Japanese data. CONSTITUTION:A reading part 11 reads out the data of document data 2 from the head in each fixed volume and divides a document into meaning paragraphs. A demonstrative pronoun detecting part 12 detects a demonstrative pronoun by comparing words/phrases read out and divided by the reading part 11 with the contents of a demonstrative pronoun table 13. The table 13 stores the data of demonstrative pronouns to be used by the detecting part 12. A demonstrative pronoun objective word/phrase judging part 14 analyzes a part of speech and attribute of each word/phrase based upon the demonstrative pronoun detected by the detecting part 12 and the words/phrases divided by the judging part 14 to judge an objective word/phrase for the demonstrative pronoun and points out both the contents to a user. Simultaneously the propriety of describing positions between the demonstrative pronoun and its objective word/phrase is judged. When the objective word/phrase is not detected, the fact is pointed out to the user.
