Title: Microphone
Inventor: NAONO HIROYUKI
IPC: H04R1/40
Filed: 1982-03-05
Abstract: PURPOSE:To collect objective sound with good S/N, by arranging plural microphone units in circular arc by taking a point as a center and summing the output of the units. CONSTITUTION:A plurality (2N+1) of microphone units Mic1-MicN are arranged in circular arc by taking a focus F as a center, the outputs of the units Mic1-MicN are summed at an adder SIGMA1 and a synthesized output is extracted from the adder SIGMA1. When a sound source is placed at the focus F, since the distance between the sound source and the units Mic1-MicN is l0, the synthesized output of the adder SIGMA1 is (2N+1) times the output of one microphone unit. When the sound source is placed at a point other than the focus F, the sound at points other than the F is cancelled with each other because of the phase difference and reduced. Then, even if a noise source exists between the focus F and the microphone units, the sound at the focus F apart from the sound source is collected excellently.

Title: Production of glass
Inventor: NODA SATOSHI
IPC: G02B15/16
Filed: 1991-02-04
Abstract: PURPOSE:To easily obtain a graded index optical element having concave distribution by firing dry gel having concave dopant distribution without breaking or foaming. CONSTITUTION:When glass is produced by a sol-gel process, pore volume distribution is rendered to gel before drying so that the pore volume is increased from the central part of the gel toward the outside. Since gel having larger total pore volume becomes nonporous at a higher temp., gel is gradually made nonporous from the central part toward the outside by increasing the total pore volume from the central part toward the outside. The gas in the gel is led from the central part to the outside and the breaking and foaming of the gel is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide sufficient strength against lateral bending stresses that work when a front working mechanism is operating, without increasing the weight of a lower boom in particular. SOLUTION: A boom for use in a front working mechanism consists of a lower boom 41 L and an upper boom, the portion of a boom foot at the base end of the lower boom 41L is pivotally attached to the bracket of an upper swing post by use of a pin, and a cross link 42 is pivotally attached to a portion on one side between the bracket and the upper boom.  The lower boom 41L comprises a box structure formed by sticking four plates 50a to 50d together using a welding means, the right plate 50c being the thickest to enhance strength, the left plate 50d being the thinnest, and the thicknesses of the front and back plates 50a, 50b being halfway between those of the right and left plates, with the front plate 50a being made thicker than the back plate 50b because a hydraulic cylinder for the booms is directly connected to the front plate 50a and therefore the driving force of the hydraulic cylinder directly works on the front plate 50a.
