Title: Cabinet structure body for audio device
Inventor: TSUKAGOSHI NOBUHIRO
IPC: H04R1/02
Filed: 1981-10-23
Abstract: PURPOSE:To improve an internal loss of a speaker diaphragm which is made of a material obtained by impregnating the synthetic resin with the flaky graphite, by selecting the polyvinyl chloride and polynorbonane for the synthetic resin with addition of an oil. CONSTITUTION:A material is compounded with 60 polyvinyl chloride, 14 polynorbonane, 6 paraffine oil, 1 stearic acid and 160 flaky graphite respectively in terms of pts.wt. Such material is left 24hr at a room temperaure, and as result the paraffin oil is absorbed to the polynorbonane. Thus the glass transistion point of polynorbonane is set at about 0 deg.C to obtain high and stable elasticity at normal temperatures. The polynorbonane that absorbed the paraffin oil is kneaded thoroughly with other compounding materials and then rolled repetitively. As a result, the flat surfaces of the flaky graphite are orientated parallel to the plane of the rolled plate material to obtain a high Young's modulus. This sheet material is formed into a cabinet baffle plate of a desired shape by an appropriate forming process.

IPC: G11B7/24047
Filed: 1987-07-10
Abstract: PURPOSE:To enhance heat resistance, reduce optical distorsion and prolong useful life, by forming a substrate of an optical disk from a resin comprising a specified polysulfone resin. CONSTITUTION:The substrate of an optical disk is formed from a resin comprising a polysulfone resin shown by formula I or II, wherein each of U and V is H or a 1-6C aliphatic hydrocarbon group, the group -X-Y-Z- is a shown by formula III or IV, and the group -X'-Y'-Z'- is the group -X-Y-Z- or a group shown by formula V.

Inventor: IKEMATSU HIROSHI
IPC: H04N19/56
Filed: 1988-07-08
Abstract: PURPOSE:To detect the moving vector of a block to be encoded without any unnecessary matching by moving a block at the border of the ineffective area on a screen to an effective area side so that the moving vector retrieval range of the block does not overlap with the ineffective area. CONSTITUTION:The block B at the border of the ineffective area D on the screen is moved to the effective area E side so that the moving vector retrieval range S of the block B does not overlap with the ineffective area D. Namely, a ROM 12 judges whether or not an aimed block is a border block adjoining to a dummy area according to a write address from a frame counter 11 and sends a switching signal to a selector 54 when the block is the border block to select a '3' input side; and the selector 54 outputs '3' to an adder 57 and adds it to a basic vector to make a shift so that the retrieval range does not overlap with the dummy area. Consequently, no unnecessary matching is performed and the moving vector is accurately detected over a wide range.

Abstract: PURPOSE:To attain a high-speed automatic equalization without adding an additional data to a signal by providing a means to detect the reproduced waveform of a test signal recorded beforehand, and by varying the parameters of the equalizer to make the said waveform close to a desirable one. CONSTITUTION:A repeating pattern is sample by an A/D converter 4 and is inputted to an arithmetic unit 8 to calculate a frequency distortion and a phase distortion.

Filed: 1989-07-03
Abstract: PURPOSE: To improve the sensitivity of diamond as a thermally luminescent material and improve the thermal luminescence response to nuclear radiation dose by previously irradiating nitrogen-containing diamond with high dose of neutrons or electrons. CONSTITUTION: This method involves a step to irradiate a singlesubstituted paramagnetic nitrogen-containing diamond with high dose of neutrons or electrons, a step to capture electrons or electron holes in lattice defects in the inside of a crystal structure of the diamond by exposing an object diamond to be irradiated to radiation, a step to generate luminescence by heating the diamond, and a step to use the luminescence as a means for measurement such as the detection or the count of nuclear radiation. Here, prior to exposure of the diamond to nuclear radiation, which is to be subjected to the detection, the count, or other measurements, the diamond is irradiated with high dose of neutrons or electrons and thus the convergence of the luminescent centers is heightened and consequently the sensitivity of diamond as a luminescent material and the thermal luminescence response to the dose of nuclear radiation are improved.
