摘要:
Polymers of a 3,4-substituted pyrrole compound substituted by an electron-attractive group having a Hammett's substituent constant (.sigma..sub.p) of 0.30 to 0.80 in at least one of the 3- and 4- positions are disclosed. The polymers are stable in the air in a dope-free state and show distinct electrochromism. Some of them are soluble in an alkaline aqueous solvent. Therefore, they are useful as electrochromic elements, etc.

A liquid ejection head including: includes an ejection orifice for ejecting liquid, a pressure chamber communicating with the ejection orifice, a flow path for supplying the liquid to the pressure chamber, and a first heat-generating element and a second heat-generating element for generating energy to be used for ejecting the liquid. The first heat-generating element is arranged in the pressure chamber before the second heat-generating element with respect to a supply direction of the liquid from the flow path to the pressure chamber. A portion between the first heat-generating element and the second heat-generating element is located within a projection of an opening of the ejection orifice, when viewed from a direction in which the liquid is ejected from the ejection orifice.

An object is to provide a heat transfer tube support structure capable of preventing deterioration of the reliability and the durability of a heat transfer tube. In a steam generator (heat exchanger) having a lower barrel (vessel), heat transfer tubes disposed in the lower barrel, and tube support plates disposed in the lower barrel and having heat transfer tube insertion holes opened in a thickness direction, support portions for supporting the heat transfer tubes are formed to the intermediate portions of the inner surfaces of the heat transfer tube insertion holes in the axial direction of the heat transfer tube insertion holes, and the regions between the support portions and the respective open ends of the heat transfer tube insertion holes are formed of inclined surfaces inclining in a radial direction outwardly in the heat transfer tube insertion holes toward the open ends, respectively.

A print head that ejects ink supplied through an ink supply port can prevent the size of satellites from being reduced while inhibiting an increase in resistance to an ink flow. In the print head, ink supply ports are arranged on both sides of a plurality of channels. A predetermined number of ink supply ports are arranged at least at one side of the ink channel all over the range of the arrangement of the channels. One side of each of the plurality of channels is connected via the common liquid chamber to the liquid supply port located so as to extend in a direction in which the channels are arranged.

In a layout pattern generating method, a specific rework cell used for edition is specified among rework cells and fill cells which are arranged in a semiconductor chip area and a specific pattern of a predetermined shape is generated in a wiring layer for the specific rework cell. A dummy wiring pattern is arranged in at least a part of the wiring layer of and the fill cell and un-specific rework cells among the rework cell other than the specific rework cell. The specific pattern is deleted from the wiring layer for the specifying rework cell. A wiring pattern is arranged in the wiring layer for the specific rework cell by wiring the specific rework cell as a logic cell.
摘要:
An electric shaver including a hand grip 10 configured to be gripped by a user' s hand, and a blade head 20 provided on an upper end of the hand grip. The blade head carries at least one shaving unit 50 comprising an outer blade foil 70 and an inner blade 80 driven in a shearing engagement manner with the outer blade foil. The outer blade foil has a plurality of holes in which hairs are introduced. The outer blade foil is elongated and has a length, and is curved along a width direction to form a generally C-shaped cross section, and is curved convexly and uniformly along its length to have a longitudinal curved outline. A radius of to curvature of the longitudinal curved outline is 150 mm to 350 mm.

A depilatory device in this invention comprises a housing, a plucking cylinder, a pinching mechanism, and a plucking mechanism. The housing is formed at its upper end with a head. The plucking cylinder is supported to the head. The plucking cylinder is driven to rotate about a longitudinal axis of the plucking cylinder. The plucking cylinder carries a plurality of pinching units. Each pinching unit is composed of a first blade and a second blade which are arranged in an opposed relation with each other. Each pinching unit has a pinching length extending circumferentially of the plucking cylinder. At least one of the first blade and the second blade is movable toward and away from the other of the first blade and the second blade to move between an opened position for making a gap and a pinch position for pinching the hair. A pinching mechanism is configured to drive the at least one of the first blade and the second blade. A plucking mechanism is configured to rotate the plucking cylinder. The at least one of the first blade and the second blade is formed at a portion intermediate its pinching length with a cutout.
