Abstract: PURPOSE:To prevent the breaking of the second layer wiring by a method wherein the first interlayer insulating film of almost same thickness as a wiring is provided on the wiring, said insulating film is removed by performing an etching wider than the width of the wiring, and the second interlayer insulating film thinner than the wiring is provided, liquid type glass is coated thereon, and a through hole is provided by performing an etching. CONSTITUTION:An insulating film 4 of almost same thickness as the first layer wiring 3 is formed on the wiring 3, and when the insulating film 4, including a through hole forming region, is removed wider than the wiring 3 by performing an etching, the height of the remaining insulating film 4 becomes almost equal to that of the wiring 3. The upper surface of the film 5 is flattened by the presence of space 12 when the second insulating film 5 is stacked, and a trough 51 is generated at the part adjoining to the wiring 3. The second layer wiring 8 is formed by flattening using liquid glass 6 and by providing a through hole 7 at the prescribed position. According to this constitution, the stepping of the through hole part is reduced in the amount of thickness of the first interlayer insulting film 4, thereby enabling to reduce the breaking of the second layer wiring 8.

Title: Effective bit output device
Inventor: NAKAMARU MASAHIRO
IPC: G11C11/41
Filed: 1990-09-18
Abstract: PURPOSE:To facilitate the output of only the effective bits even at the time of asynchronous reading out by outputting only the effective information by deciding that the output information exclusive of the outputs between a set start timing and an end timing is effective. CONSTITUTION:The bit data 1 and inversion bit data 2 are stored and held in a storing means 1 in accordance with a clock CK1 which is a reference timing and are outputted from an output means 2 according to a read signal. A deciding means 3 is set with the ineffective signal which is the start timing earlier by the prescribed time than the reference timing and the effective signal slower by the prescribed time and produces the output by deciding that the output from a means 2 outputted between the ineffective signal and the effective signal is ineffective and the output read out during the time exclusive thereof is effective. The output of the transition information at the updated bit change point is suppressed and only the effective information is outputted even in the case the information reading out is executed asynchronously.

Title: Contention control system in its own path selection type switching network
Inventor: SHIMIZU HIROSHI
Filed: 1987-10-05
Abstract: PURPOSE:To prevent a signal block from being deleted at the time of generating collision in the signal block by informing a competitive state to all of the input terminals except all the input terminals or one input terminal colliding with each other set to a collision point in the case of generating the collision by a signal from plural input terminals. CONSTITUTION:Assuming that the signal block of a simultaneous routing address '11' is delivered from the input terminals 1 and 4, the collision is generated at a unit switch 15. The control part 30 of the unit switch 15, when detecting the fact, sets the signal path of the signal block on one side at an output terminal 43, and stops the setting of the signal path on the signal block on the other side, and sends a contention detecting signal to the input terminal. Thus, by folding the contention detecting signal at the input terminal, it is possible to make the provision of a buffer for waiting at every unit switch unnecessary.

Title: Silver halide particle, silver halide photographic sensitive material, silver halide emulsion, chemical maturation method and chemical sensitizing nucleus
Inventor: FURUSAWA NAOKO
IPC: G03C1/07
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To obtain high sensitivity by providing the silver halide emulsion with chemical sensitizing nuclei having the max. size of a specific value or above and specific value or below in the diameter of the circle of equal projected area. SOLUTION: This silver halide emulsion has the chemical sensitizing nuclei having >=0.2 to <4.0nm max. size in the diameter of the circle of the equal projected area. In such a case, the max. size of the chemical sensitizing nuclei refers to the size of the chemical sensitizing nuclei formed on one particle of the silver halide. If the max. size of the chemical sensitizing nuclei is below 4nm, the induction period before the start of development is equal to the fogging of the non-sensitized emulsion and the fogging by the chemical sensitization dies not at all. If, however, the size exceeds 4nm, the induction period is gradually shorter and if the size is >=6nm, the induction period is equal to the latent image of the developable smallest size.  As a result, the fogging accompanying with the increase in the sizes of the chemical sensitizing nuclei is suppressed to min. and the high sensitivity is obtd.
