Abstract: In a power conversion system, a control circuit has, as its operation modes: a first control mode in which control circuit controls a DC-DC converter at a first drive frequency; a second control mode in which control circuit controls DC-DC converter at a second drive frequency higher than first drive frequency; and a third control mode in which control circuit controls DC-DC converter at a third drive frequency higher than first drive frequency. Control circuit is configured to change operation mode from first control mode into second control mode when detector circuit detects a predetermined change in output voltage while control circuit is operating in first control mode. Control circuit controls DC-DC converter in third control mode in a process of changing, in response to detection of predetermined change, operation mode from first control mode into second control mode before starting to control DC-DC converter in second control mode.

Abstract: A nutrient intake amount estimation system according to an embodiment includes: a sensor that is disposed in a toilet space, and configured to detect an excretion smell related to excretion of a user of the toilet space; an estimation unit configured to estimate an estimated nutrient intake amount that is an amount of nutrients taken by the user by using an output of an estimation model that outputs information indicating an amount of nutrients estimated to be taken by the user in accordance with an input based on an output value of the sensor; and an output unit configured to output information based on the estimated nutrient intake amount.

Abstract: A conductive paste used for forming conductive sinters includes a mixture of a copper powder coated with a metal oxide and a metal oxide powder, and an organic vehicle. The content of the metal oxide used for coating the copper powder is in the range of about 0.05% by weight to about 5% by weight of the total weight of the copper powder coated with the metal oxide and the metal oxide powder, and in addition, the total content of the metal oxide used for coating the copper powder and the metal oxide powder is in the range of about 1% by weight to about 12% by weight of the total weight of the copper powder coated with the metal oxide and the metal oxide powder.

Abstract: A monolithic ceramic substrate includes a green laminate having a plurality of green functional ceramic layers including a functional ceramic material, green support layers including a ceramic material that does not sinter at a sintering temperature for the green functional ceramic material to prevent shrinkage of the functional ceramic layers, first conductor patterns including a thin-film conductor, and second conductor patterns including a thick-film conductor. The green laminate is fired at the sintering temperature for the green functional ceramic material.

Abstract: Disclosed are a Ti--Al alloy including aluminum (Al) in an amount of 30 to 38% by weight, nitrogen (N) in an amount of 0.2 to 1.0% by weight, and titanium (Ti), substantially the balance, and a process for producing the same. Since the Ti--Al alloy includes the nitrogen in the predetermined amount, the microstructure of the Ti--Al alloy can be micro-fined and made into a uniform one, and accordingly the shrinkage cavities can be reduced remarkably. Therefore, the strength, the ductility or the like of the Ti--Al alloy can be improved remarkably. With the production process, it is possible to produce the Ti--Al alloy including the nitrogen in the predetermined range.
