Title: Method for raising thermoelectromotive force of temperature differential battery
Inventor: IKESHIYOUJI TAMIO
IPC: G01K7/00
Filed: 1983-12-14
Abstract: PURPOSE:To raise the thermoelectromotive force of a temperature differential battery by adding to the electrolytic solution of the battery a complexing agent which can form a complex with ions contained in this electrolytic solution. CONSTITUTION:A complexing agent is added to an electrolytic solution 3 of a temperature differential battery. Thus the ions are complexed in accordance with the equilibrium constants for a complex forming reaction, and, as a result, the entropy of ions changes, and consequently the thermoelectromotive force also changes. When this change of entropy is positive, the thermoelectromotive force is changed in the negative direction, but, when the change of entropy is negative, the thermoelectromotive force is changed in the positive direction. Depending upon the kind of electrode reactions, the thermoelectromotive force may be positive or negative. To make the thermo-electric conversion highly efficient, the thermoelectromotive force is made large in its absolute value. In this way, the thermoelectromotive force can be raised.

Title: Aluminum alloy
Inventor: TOMA KEN
IPC: C22C21/10
Filed: 1986-10-06
Abstract: PURPOSE:To manufacture an active Al alloy for hydrogen formation, etc., by incorporating specific amounts of In and Zn to Al and by carrying out casting at a specific cooling velocity. CONSTITUTION:An alloy consisting of, by weight, about 0.05-2% In, about 0.1-5% Zn, and the balance Al is cast at a cooling rate of >=1 deg.C/sec so as to be formed into an Al alloy. This Al alloy is remarkably electrochemically base and is chemically active, so that it reacts with water to form H2 gas efficiently. In this Al alloy, the activating effect is reduced when the additive quantity of In is by far less than 0.5% and, when it exceeds 2% to a great extent, problems occur at the time of casting and heat treatment and the activating effect is not remarkably improved in proportion to the increase in the additive quantity. Zn produces activating effect to a greater extent by synergistic effect with In and, in order to make this synergistic effect more marked, an additive quantity of >=0.1% is required, but, even if it exceeds 5%, the effect by the addition is not remarkably improved proportionately with the increase in the additive quantity, though the degree of activation is not reduced.

IPC: G11B20/14
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To obtain an optical disc and the spindle servo circuit for the playback unit therefor in which the sync pattern can be detected easily while discriminating from the maximum inversion interval in the data even for a CLV type optical disc. SOLUTION: The optical disc has sync marks for obtaining the sync signal for reading data, and data fields for obtaining the mark indicative of a data on each track. Assuming the 1 bit interval of data is T, the length of sync mark in the direction of track is nT, the detection error at the time of reading the sync mark is αT, and the maximum inversion interval of mark for the data is mT, they are set to satisfy the following relationships; (n-α)T>mT and mT×(n+α)/n<nT. Consequently, the length of sync mark can be set while taking account of variation in the r.p.m. of disc and the sync pattern can be detected while discriminating from the maximum inversion interval in the data even for a CLV type optical disc.
