An ink-jet head includes a nozzle array including plural nozzles. The nozzle array has a first nozzle group arranged in the center thereof and second nozzle groups arranged further on outer sides than the first nozzle group. Inter-nozzle pitches of the second nozzle groups are larger than inter-nozzle pitches of the first nozzle group. A direction in which nozzles of the second nozzle group eject an ink and a direction in which nozzles of the first nozzle group eject the ink are different.

The present invention provides a plate-like protect member at a front surface of an ink jet printer head having an orifice which is capable of jetting ink. The protect member provides a step around the orifice having an outer portion higher than an inner portion. The protect member also provides an ink repellency layer on an outer portion of the step. Thus, the ink jet printer head of the present invention can prevent the jetted ink from the orifice to creep up toward back of the ink jet printer head which is reverse direction to the ink jetting direction.

Bump electrodes (conductive members) bonded onto lands disposed at a peripheral portion side than terminals (bonding leads) electrically coupled to pads (electrode pads) of a microcomputer chip (semiconductor chip) are sealed with sealing resin (a sealing body). Thereafter, the sealing resin is ground (removed) partially such that a part of each of the bump electrodes is exposed. The step of protruding the part of each of the bump electrodes from a front surface of the sealing resin is performed, after the grinding step.

Disclosed is a passenger protection device (12) for a vehicle, which protects a passenger (Mn) sitting on a seat (11) when an external force (Fs) is applied to a side surface (16a) of a vehicle body (16). The passenger protection device has a side support (14). The side support is provided on the side portion of a seat back (46), and supports the upper body (Bu) of the passenger. The side support has a deformable portion (47). The deformable portion allows the side support to be deformed by an external force having a predetermined value or more.

Provided is a substrate for a thin-film photoelectric conversion device which makes it possible to produce the device having improved characteristics at low cost and high productivity. The substrate includes a transparent base member, with a transparent underlying layer and a transparent electrode layer successively stacked on one main surface of the transparent base member. The underlying layer includes transparent insulating fine particles and transparent binder, and the particles are dispersed to cover the one main surface with a coverage factor of particles—ranging from 30% or more to less than 80%. An antireflection layer is provided on the other main surface of the transparent base. The antireflection layer includes transparent insulating fine particles and transparent binder, and the particles are dispersed to cover the other main surface with a coverage factor greater than the underlying layer.

Disclosed is a polyimide film which is free from coarse particles caused by aggregation of a filler, therefore, can avoid abnormal electrical discharge during a discharge treatment, repelling during application of an adhesive, and the like. Also disclosed is a method for production of the polyimide film. The method for production of the polyimide film is characterized by using an organic solvent solution containing an inorganic filling material and a first polyamic acid, wherein the organic solvent solution containing the first polyamic acid is prepared by a process comprising the steps of: 1) preparing a dispersion solution which contains the inorganic filling material and a second polyamic acid and has a viscosity of 50 to 500 poises; 2) filtering the dispersion solution; 3) mixing a prepolymer solution containing the first polyamic acid in the process of being polymerized and having a viscosity of 100 poises or lower with the filtered dispersion solution; and 4) increasing the viscosity of the mixed solution to a level ranging from 1000 to 6000 poises.
