Title: Testing method of magnetic recording-reproducing characteristics
Inventor: OGAWA KOUICHI
IPC: G11B33/10
Filed: 1977-12-30
Abstract: PURPOSE:To rapidly and accurately measure and evaluate various factors associated to recording and reproduction from the resultant characteristics without any personal error by writing square wave signals to a recording medium and performing the Fourier analysis thereof. CONSTITUTION:Signals of low frequencies below 1/10 of the frequencies of ordinary read-write signals (1, 0 signals, hence square waves) are written in a recording medium 1 by a writing device. The apparatus is so constituted that after these are read with a head 2 and are amplified with an amplifier 3 they are subjected to Fourier analysis with a spectrum analyzer 4. The results of this measurement give the characteristics expressed in terms of frequency (f) to spectrum density Sd, from which the factors associated to recording and reproduction such as material of magnetic heads, production conditions and recording-reproducing conditions such as floating quantity of heads and write currents are measured and evaluated, thus these factors may be measured and evaluated extremely simply and highly accurately without any personal error.

Title: Leg body of sewing machine
Inventor: MORIOKA HISAYOSHI
IPC: D05B75/04
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To attain low vibration so that a resonance phenomenon by exciting force of a sewing machine is not generated by constituting a characteristic frequency of a leg body so as to become prescribed time or more of a frequency of the exciting force. SOLUTION: A sewing machine, particularly, an industrial sewing machine is heavy in weight, and since particularly a multi-head embroidering sewing machine or the like reaches even several hundred kilograms, a characteristic frequency inevitably becomes low, and a characteristic frequency of a leg body 5 results in being less than a frequency of exciting force. Therefore, when the sewing machine is operated, since bending of a leg by vertical directional exciting force within working rotating speed and resonance of a translation mode in the longitudinal and lateral direction of the leg body 5 are generated, it becomes a big problem, Then, in order that a resonance phenomenon by exciting force by the sewing machine is not generated, a characteristic frequency of the leg body 5 is constituted so as to become √2 times a frequency of the exciting force.  Though a characteristic frequency of the leg body 5 generates resonance in the case of 0.8 times to √2 times, when it is set not less than √2 times, the resonance is not generated.

Title: Maximum power control method for solar battery
Inventor: YAMAMOTO ISAMU
IPC: G05F1/67
Filed: 1995-06-26
Abstract: PURPOSE: To simplify the hardware by decreasing an extracted current when a product between a differentiated output power and a differentiated output voltage is positive and increasing the extracted current when the product between the differentiated output power and the differentiated output voltage is negative so as to shift the operating point toward a maximum power point. CONSTITUTION: The product between the differentiated output power of a solar battery and the differentiated output voltage is always positive in a region where an operating point is less than an optimum operating voltage Vopt and always negative in a region where the operating point is more than the optimum operating voltage Vopt. When the product is positive, the output power is increased by reducing the extracted current to shift the operating point toward the maximum power point Pmax. Conversely, when the product is negative, the output power is decreased by increasing the extracted current to shift the operating point toward the maximum power point Pmax. Thus, the battery is operated so that the operating point traces the maximum power Pmax at all times for optional solar insolation intensity not relying on past history.

CONSTITUTION:An optical recording media formed on a plastic substrate are crystallized and formed after the intermetallic compound and the metal are alternately laminated. For example, an SiO2 insulating film with the thickness of about 1,000Angstrom  is formed on a PMMA substrate with the thickness of 1.2mm, and thereafter, the evaporating speed of In and Sb is kept to 0.5-2.0Angstrom /sec, the binary evaporation is executed and the InSb alloy with the atomic weight % of 40:60 is layer-formed to the thickness of about 1,000Angstrom . For the method, when In and Sb are both vaporized, so that the atomic weight ratio of the evaporating substance can be 1:1, the vaporizing speed is adjusted, to make the thickness of the film with about 100Angstrom , next, the evaporating source of In is interrupted, only Sb is evaporated to the thickness of about 100Angstrom , next, the interruption of In is stopped and the binary evaporation of In and Sb is executed. Thus, the repeating evaporations of five times are executed, the film formation of about 1,000Angstrom  is performed and the thermal processing is executed to said film.
