Abstract: A screw compressor for compressing a working medium sucked through a suction opening and discharging the compressed working medium through a delivery opening, wherein the screw compressor includes: a male rotor and a female rotor that rotate while meshing with each other; a casing that houses the male rotor and the female rotor and is provided with a bore which forms a working chamber designed, together with the male rotor and the female rotor, to compress the working medium; a drive unit that rotationally drives at least one of the male rotor and the female rotor; a working chamber closing unit that forms a suction port for sucking the working medium into the working chamber and closes the working chamber when the working chamber reaches a specified capacity; and a suction space that connects the suction opening and the suction port to allow communication therebetween, wherein an open space that connects the suction opening and the suction port to allow communication therebetween is provided between a shaft

Abstract: A semiconductor memory device includes finger structures arranged in a first direction, a bit line disposed on one side in a stacking direction with respect to the finger structures, and an inter-finger insulating layer disposed between two finger structures. A first finger structure includes conductive layers, a semiconductor layer opposed to the conductive layers, a first insulating layer disposed between the bit line and the conductive layers, and a second insulating layer disposed between the first insulating layer and the conductive layers. A distance between the first insulating layer and the inter-finger insulating layer at a position corresponding to a surface on a side of the bit line of the first insulating layer is larger than a distance between the second insulating layer and the inter-finger insulating layer at a position corresponding to a surface on an opposite side of the bit line of the second insulating layer.

A preferred aspect of the invention provides an information processing device including: an agent configured to output a response based on a state observed from an environment with stochastic state transitions; an individual evaluation model configured to evaluate the response assuming that a part of the stochastic state transitions occurs; and a plan explanation processing unit configured to output information based on the evaluation in association with information based on the response.

Abstract: A plan evaluation apparatus, which evaluates a schedule planned by combining a plurality of plans, includes: a feature conversion unit that divides the schedule into plan components based on a predetermined conversion rule, and convert the divided plan components into features; a model learning unit that uses the features as an input and creates a machine learning model having a key performance indicator (KPI) of the schedule as an objective variable; a contribution rate calculation unit that calculates a contribution rate of each of the features with respect to the machine learning model; and an influence degree calculation unit that calculates an influence degree of influence, on the KPI of the schedule, of the plan component which is a conversion source of the feature, based on the contribution rate of the feature.

Abstract: A sensing device that senses a substance to be sensed as a gas by causing a piezoelectric resonator to adsorb the substance to be sensed, includes: a substrate, a thermoelectric element unit, a support plate, and a base portion. A sensing module unit in which a substrate, a thermoelectric element unit, and a support plate are integrated is removably disposed to a base portion that performs at least one of heat supply and heat dissipation to the thermoelectric element unit.

Abstract: A substance detection system and a substance detection method are provided. The temperature identifying portion identifies a surface temperature of the quartz substrate, based on a difference between a deviation of the fundamental wave frequency from at least any predetermined reference fundamental wave frequency of the reference crystal resonator and the detecting crystal resonator and a deviation of the third harmonic frequency from a predetermined reference third harmonic frequency. The substance identifying portion identifies a temperature at which a contaminant attached to the detecting crystal resonator is desorbed from the detecting crystal resonator to identify the contaminant based on the temperature at which the contaminant is desorbed.
