Title: Diaphragm for loudspeaker
Inventor: TAKIZAWA TOSHIHIDE
IPC: H04R7/02
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To lower the minimum resonance frequency, to make a diaphragm body highly stiff and to reproduce sounds with low distortion over a broadband by constituting a resin film that integrally forms a body and an edge part of its circumference and another resin film that is pasted to the body. SOLUTION: An edge part 1 that is arranged at the circumference of a diaphragm body 2 for a loudspeaker is composed of a resin film and is integrally formed with body 2. Here, another film 3 is pasted, overlapping the body 2 to make the diaphragm stiff. As the other film 3, if paper is used, for instance, high stiffness is obtained and a low distortion sound quality is acquired. Because high stiffness is acquired by sticking the other films 3 together, it is possible to make a resin film forming the part 1 thin, and consequently a minimum resonance frequency is lowered.

Title: How to determine front and rear of flat mask
Inventor: HIRAYAMA KAZUNARI
IPC: H01J9/42
Filed: 1982-10-08
Abstract: PURPOSE:To accurately determine the front and rear of a flat mask in a non- contact method by spacing an eddy current type non-contact displacement gauge at specified intervals from the surface of the flat mask and determining the front and rear depending upon the magnitude of the output voltage. CONSTITUTION:Since the hole area ratio (%) in a fixed area when the surface (front) with the small hole 7 of a flat mask 6 is opposedly spaced at specified intervals (d) to an eddy current type non-contact displacement gauge 3 is smaller than that (%) when the surface (rear) with the large hole 8 of the flat mask 6 is opposedly spaced at specified intervals (d) to the eddy current type non-contact displacement gauge 3, the output from the displacement gauge is set to 5.40V, for example, on a straight line 15 when the rear is measured provided that the output from the displacement gauge is set to 4.22V, for example, when the front is measured. As a result, the front and rear of the flat mask can simply be determined depending upon the magnitude of the output voltage of the eddy current type non-contact displacement gauge.

Title: Carbon fibre reinforced composite material
Inventor: OKAMOTO HISAO
IPC: B64C1/00
Filed: 1988-07-15
Abstract: PURPOSE:To absorb the inner warpage during the manufacturing period, and prevent the occurrence of a layer cracking or the crack produced by an outer stress by making the carbon fibres of high strength or high elasticity and the carbon fibres of low strength or low elasticity in a laminated state. CONSTITUTION:High strength and/or high elasticity carbon fibres, and low strength and/or low elasticity carbon fibres are in a laminated state. For instance, they are heat and press-molded in laminating respectively at the rate of one layer of low strength carbon fibre prepreg relative to three layers of high strength carbon fibres prepreg. By this manner, a carbon fibre reinforced composite material consisting of carbon/phenol resin is obtained, which is used as a back-up member 2 arranged on the nozzle insert part of a solid propelling rocket 1. Since the inner stress due to the difference of the thermal expansion coefficient generated in the process of being cooled from the molding of resin and the curing temperature is absorbed in by low strength and/or low elasticity carbon fibres, the carbon fibre reinforced composite material obtained through this manner is never produced with layer cracking owing to the difference of thermal expansion coefficient, and the residue of large inner stress after cooling can be prevented from occurring.

Abstract: PURPOSE:To reduce the wiring resistance of each section, and to improve the degree of integration by mutually connecting one parts of a plurality of high resistance wiring regions by another low resistance wiring different from low resistance wiring in the semiconductor integrated circuit with a plurality of the high resistance wiring regions, which are connected to said same low resistance wiring and through which currents do not flow simultaneously. CONSTITUTION:In an example of which a power supply line V is connected to the ends of the drains of transistors Q1, Q2, Q3, the resistance of drain high resistance sections can be lowered by connecting other ends at V' different from wiring V, and other wiring can be arranged onto elements. Since periods during which the Q1, Q2, Q3 are at ON each differ particularly, currents are shunted to the high resistance wiring sections through which currents do not flow in a respective moment, thus displaying effects.
