Provided is a sound output device including a drive unit that has a sound output section inside and that is formed in an annular shape and an electric unit that has a drive control section inside and that is coupled to the drive unit. A space inside the drive unit is formed as an intake hole that takes in an external sound. The sound output device is attached to an ear with the drive unit inserted into a cavum concha. Accordingly, in a state in which the electric unit is coupled to the drive unit and the drive unit is inserted into the cavum concha to be attached to the ear, an external sound taken in from the intake hole that is the space inside the drive unit goes to the external auditory canal. Therefore, a stable and favorable wearing state on the ear can be ensured, and at the same time, a state in which an external sound is taken in naturally can be ensured.

Sound output device

This is a control method for a vehicle, the vehicle including an electric generator, an engine coupled to the electric generator, a drive motor configured to drive the vehicle, and a battery electrically connected to the electric generator and the drive motor, electric power generated by the electric generator being configured to be supplied to at least one of the battery and the drive motor. The control method is including: calculating, when a temperature of the battery is equal to or lower than a predetermined temperature, a drive torque target value based on required electric power of the vehicle and a state of the battery, controlling a torque of the electric generator based on the drive torque target value, and controlling a rotation speed of the engine based on a predetermined reference low rotation speed, thereby performing a low electric power generation control for causing the electric generator to generate electric power.

To improve quality of a radome using a cyanate ester resin for a skin layer. A radome is formed of a multilayer structure in which a plurality of skin layers are layered on a surface of a core member. The plurality of skin layers include a first fiber reinforced plastic layer containing the cyanate ester resin and a fiber material and a second fiber reinforced plastic layer containing an epoxy resin and a fiber material. The second fiber reinforced plastic layer is disposed at a position in contact with the surface of the core member. A proportion of a thickness of the second fiber reinforced plastic layer to a thickness of all of the skin layers is preferably 50% or less.

Radome

A method of molding a sandwich panel includes a step of providing, on one or both surfaces of an (a) core material, a prepreg or the prepreg and an adhesive as a (b) skin material. The (a) core material is a super engineering plastic foam having a glass transition temperature of greater than 200° C. The (b) skin material contains: a (b-1) epoxy resin having an average molecular weight of 1300 or more or having a trishydroxymethane-type or cresol novolac-type structure and containing, in a total epoxy resin, an amount of 70 to 100 mass % of an epoxy resin that is semi-solid or solid; a (b-2) epoxy resin containing, in the total epoxy resin, an amount of 0 to 30 mass % of an epoxy resin that is liquid; and a (b-3) curing agent.

Sandwich panel molding method

A hybrid control method controls a hybrid vehicle. A control unit sets a rotational speed threshold value at which a continuous gear tooth striking sound occurring in a gear mechanism connecting an electric power generation motor to the internal combustion engine is not a problem in terms of vehicle quality. The control unit generates negative pressure while maintaining the engine rotational speed in the firing state where the engine rotational speed is equal to or greater than the rotational speed threshold value. Also, the control unit generates negative pressure after switching from the firing state to a motoring state where the internal combustion engine is rotated by the electric power generation motor and where the engine rotational speed is less than the rotational speed threshold value.

A sound output device includes a device main frame in which at least a speaker is disposed, and an attachment aid member that is joined to the device main frame. In the sound output device, the attachment aid member includes an annular support portion at least a part of which is inserted into a cavum concha, and the annular support portion includes a contact portion that comes into contact with a part of an ear in the cavum concha while being elastically deformed. With this arrangement, the contact portion of the annular support portion inserted into the cavum concha comes into contact with a part of the ear in the cavum concha while being elastically deformed. Accordingly, it is possible to attach the sound output device to the ear, using the attachment aid member, regardless of the size and the shape of the ear.

A hybrid vehicle control method is provided for a hybrid vehicle having an engine and a generator directly connected via a gear train having a plurality of gears that are engaged with each other. In this hybrid vehicle control method, a prescribed torque is continuously applied to the generator upon determining the engine is in a rotating state such that a transmission torque of the gear train does not continuously fluctuate above and below zero torque. Preferably, in one embodiment, the prescribed torque continuously applied to the second motor/generator is a negative torque value during a power generation operation in which the generator is rotated by the engine and is a positive torque value during a motoring operation in which the engine is rotated by the generator.
