Title: Image pickup method
Inventor: MARUTA HIDEO
IPC: G03B15/03
Filed: 1985-02-21
Abstract: PURPOSE:To acquire surely the outline and the center of an object by discharging the illuminating light, which illuminates the object, from the node of lens systems constituting an image pickup device. CONSTITUTION:When an illuminating light L is discharged toward an object 5 from a node N of the first and the second lens systems 3 and 4, the illuminating light L reflected from the object 5 takes the same optical path that the light is emitted from a light source 6 and illuminates the object 5 on. That is, the going path and the returning path of the illuminating light L coincide with each other. As the result, shapes of objects 5a and 5b which are put one over the outer are acquired accurately by a solid-state image pickup element 7 on which images of objects 5a and 5b are focused because a shadow (s) of the upper object 5a is not projected large on the surface of the lower object 5b when they are irradiated. Though the object 5 has a glossy surface, the halation does not make it difficult to acquire the outline of the object 5 unless the normal of the surface is directed to lenses because the illuminating light L reflected regularly from the object 5 is not made incident on an image pickup device 1.

IPC: H01L21/316
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming an insulation film of low dielectric constant which is proper for a manufacturing process of a semiconductor device. SOLUTION: A material film 14 formed of silicon oxide containing impurities wherein oxide becomes water soluble is formed on a substrate 11. The material film 14 is split into a nonaqueous material phase 15a consisting of silicon oxide and a water soluble material phase 15b consisting of oxide of impurities by carrying out heat treatment and the dispersion layer 15 wherein the water soluble material phase 15b is dispersed in the nonaqueous material phase 15a is formed. The dispersion layer 15 is converted to an insulation layer 16 by forming cavities C in the non-water-soluble material phase 15a by selectively etching and removing the water soluble material phase 15b in the dispersion layer 15 by using water as an etchant.  Thereby, the insulation film 16 wherein the dispersion state of the cavities C is held satisfactorily is formed without using an etchant such as an acid which corrodes a wiring material.

Title: Manufacture of ink jet head
Inventor: MIZUNO RYUKICHI
IPC: B41J2/135
Filed: 1990-02-15
Abstract: PURPOSE:To permit the formation of an opening part having a highly dimensionally accurate hole diameter by providing as a nozzle forming member a resin membrane having formed therein a nearly circular opening part smaller in hole diameter than an opening part provided in a metal plate and approximately concentric therewith. CONSTITUTION:A nozzle forming member 22 is of a lamination layer formed by a metal plate 41 having an opening part 44 and a resin membrane 42 having an opening part 46 smaller in hole diameter than the opening part 44. A recording ink is supplied from the metal plate 41 and discharged from the resin memberane 42. Since the hole diameter of the opening part on the ink-discharging surface produces a great effect on printing quality, it is necessary to make the nozzle forming member as thin as possible and the diameter of the opening part highly dimensionally accurate. On the other hand, in order to prevent the occurrence of vibration and deformation of the nozzle forming members due to the pressure of the ink at the time of discharging, the nozzle forming member is required to be made thick. By forming into a lamination layer the metal plate for enhancing mechanical strength and the resin membrane capable of forming therein the hole with a highly dimensionally accurate diameter, the requirements for the mechanical strength and the dimensional accuracy of the hole diameter can be met simultaneously.

Title: Formation of multicolor latent image
Inventor: MIYAGI KOUJI
IPC: G03G5/02
Filed: 1982-03-08
Abstract: PURPOSE:To improve reproductivity at the areas low in density, and to obtain a good 2-color copy free from color mixing, by using a photoreceptor obtd. by laminating a photoconductive layer having rectification ability and an insulating layer on a conductive substrate, and carrying out operations in accordance with a specified procedure. CONSTITUTION:A photoconductive layer and an insulating layer are laminated on a conductive substrate to form a photoreceptor and it has rectification function of injecting only one polarity charge from the conductive substrate. Surface potential of the photoreceptor is accorded with the potential of the latent image of the part corresponding to the red color immediately before, in a tertiary charging process for applying AC discharge properly superposed with DC bias voltage. As a result, the potential difference (contrast) between the red part and the white part at the time of black developing is controlled perfectly to zero, and the potential difference (contrast) between the black part and the white part can be made max., thus preventing mixing of a black toner into the red part, and permitting a 2-color copy superior in gray low density reproducibility to be obtained.
