In computer and video games in which a character is managed by registering an ID assigned to an object, objects corresponding to the same player can be duplicately registered, and a bonus that increases the ability of the player corresponding to the duplicately registered object is granted.

A transmission includes a controller being provided with a change-speed stage anticipator. The controller adopts a time, which one of the transmission's gear-mechanism selectors requires in shifting a current change-speed stage to another change-speed stage, as a pre-shift time for selecting the latter change-speed stage. The change-speed stage anticipator operates the one of the gear-mechanism selectors while adopting a temporary change-speed stage as a subsequent change-speed stage when the temporary change-speed stage, which is estimated from a state of vehicle after the pre-shift time, the state of vehicle being relevant to each element of an anticipated change-speed stage group that is made up of one or more of the change-speed stages that can be selected by the one of the gear-mechanism selectors being set on one of the transmission's input shafts that is disconnected from a power source, coincides with an anticipated change-speed stage that corresponds to the pre-shift time.

A multi-blade fan includes a support body rotatable about a rotary shaft, and a plurality of blades secured to the support body such that an inter-blade pitch angle relative to the rotary shaft assumes a prescribed arrangement. The blades extend along an axial direction of the rotary shaft. The plurality of blades are disposed such that, with respect to amplitude values of periodic functions at individual orders when the prescribed arrangement is expanded in a periodic Fourier series, a maximum amplitude value is less than 200% of a second-largest amplitude value.

The present invention provides an odor modulation method that makes it possible to modulate, into a different odor, the unpleasant, bad odor that is generated when excrement is sucked from a toilet by a sanitation vehicle or discharged from the sanitation vehicle, thereby making it possible to easily reduce the harm done by the bad odor. An odor modulation method that is characterized by having: a step in which a vacuum pump reduces the pressure of a feces / urine tank of a sanitation vehicle and excrement is sucked through a hose that is connected to the feces / urine tank; and / or a step in which the vacuum pump increases the pressure of the feces / urine tank and excrement is discharged through the hose that is connected to the feces / urine tank. The odor modulation method is also characterized in that lubricating oil used in the vacuum pump contains an odor-modulating oil.

The invention discloses light-odor heat-resistance polystyrene resin and a preparation method thereof. The light-odor high-heat-resistance polystyrene resin comprises the following components in percentage by weight: 90 to 99.5 percent of high impact polystyrene (HIPS) resin, 0.1 to 5 percent of molecular sieve, 0.1 to 1 percent of antioxygen, and 0.1 to 4 percent of processing assistant, wherein the molecular sieve is a one-dimensional or multi-dimensional porous structure; and in the molecular sieve, the molar ratio of a silicon element to an aluminum element is 2 to 50. The preparation method of the flame-retarding polystyrene resin with high glow-wire ignition temperature comprises: weighing the components according a weight mixing ratio; mixing the components in a high-speed mixer for 3 to 5 minutes; and extruding and granulating the mixed material in a screw extruder. The light-odor high-heat-resistance polystyrene resin has high heat resistance and light odor and meets the requirements of an environment-protection trend.

The invention provides a power converting apparatus. In the power converting apparatus, unpleasant noise caused by switch action is suppressed while zero-phase current generated by switch action is decreased. The power converting apparatus comprises a DC circuit, a first converting circuit, a second converting circuit, and a controller. The DC circuit contains a first potential and a second potential. The first converting circuit is connected between a first multi-phase AC circuit and the DC circuit and performs power transformation between DC and AC with a switching element. The second converting circuit is connected between a second multi-phase AC circuit and the DC circuit and performs power transformation between DC and AC with a switching element. The controller controls the first converting circuit and the second converting circuit. The controller performs control in order that when more than two phases of the first converting circuit are simultaneously converted from the first potential to the second potential, at least one phase of the second converting circuit is converted from the first potential to the second potential.

PROBLEM TO BE SOLVED: To provide a group management control method for an elevator system capable of reducing uncomfortableness caused by waiting in a cage.SOLUTION: In a group management control method for an elevator system that manages a plurality of elevators, with a plurality of cages connected together in a single rising / falling passage, based on boarding spot call registration information and destination floor call registration information, a predicted in-cage wait frequency, a predicted in-cage wait time, and a predicted in-cage congestion degree are calculated by adding the number of passengers predicted for each of boarding floor and destination floor under a predetermined condition, to a current use state. Based on them, a predicted uncomfortableness degree evaluation value of each elevator is calculated, and by using the calculated predicted uncomfortableness degree evaluation value, a cage to be allocated to each floor is decided.

The present invention provides a lubricating oil which can easily reduce harm caused by malodor by converting malodor into different malodor when treating air containing malodor generated in the living environment or industry in daily life or a malodor generation source with a machine. The present invention provides a lubricating oil characterized by containing an oil agent for odor conversion, the oil agent for odor conversion containing an odor conversion component and an oil agent component, and the odor conversion component containing at least one oxygen-containing heterocyclic compound selected from the group consisting of furan compounds and pyran compounds.
