Abstract: Provided is a robot that realizes human-like movements. A robot (1) comprises: a self-propelled drive unit (11); a trunk unit (12) mounted on the drive unit (11); and a head unit (14) installed above the trunk unit (12). The head unit (14) has an image capturing unit (142), and a transmission unit for transmitting an image captured by the image capturing unit (142) as a signal to a user terminal. The robot (1) comprises: a cover (15) that is swingable and covers the trunk unit (12) so as to provide a space between the trunk unit (12) and the cover (15); and a first coil spring (161) and a second coil spring (171) disposed between the trunk unit (12) and the cover (15).

Abstract: The present invention provides a robot that demonstrates human-like motion. A robot (1) is provided with: a self-traveling driving part (11); a body part (12) mounted on the driving part (11); and a head part (14) provided above the body part (12). The head part (14) is provided with: an imaging unit (142); and a transmission unit that transmits a video image captured by the imaging unit (142) to a user terminal as a signal. The robot (1) is provided with a cover (15) that covers the body part (12) so as to have a space between the cover and the body part (12) and can be flapped being supported on the upper end thereof.

Abstract: Disclosed is a charge transfer complex capable of obtaining a curable resin composition having an excellent balance between curability and storage stability when used as an epoxy-resin curing agent. The charge transfer complex has an imidazole moiety as an electron donor moiety. The charge transfer complex may be an assembly wherein electrons included in a compound (a) having an imidazole moiety are accepted by a compound (b) having an electron acceptor moiety, or may be a compound having an imidazole moiety and an electron acceptor moiety in its molecule, and the electron acceptor moiety accepts electrons included in the imidazole moiety.

Abstract: An ozone generator (100) includes: a flow path (1) through which gas flows from an inlet (5) to an outlet (6); an ozone generation unit (3) disposed in the flow path (1); and an ozone sensor (4) disposed in the flow path (1) and upstream of the ozone generation unit (3). The flow path (1) has an upstream-side flow path (130) that forms a gas passing space (AR) located upstream of the ozone generation unit (3) and through which the gas flows from one side to another side in a predetermined direction. The inlet (5) is disposed closer to an outer circumferential portion (131) of the upstream-side flow path (130) than the ozone sensor (4).

Abstract: A gas laser apparatus according to an aspect of the present disclosure includes a main discharge circuit that supplies main discharge voltage that causes main discharge to a pair of main discharge electrodes, and a pre-ionization circuit that supplies pre-ionization voltage that causes corona discharge to a pre-ionization electrode. The main discharge circuit includes a step-up pulse transformer, a main capacitor and a switch connected to a primary side of the step-up pulse transformer, a first power source that charges the main capacitor, a first capacitor connected in parallel to a secondary side of the step-up pulse transformer, a first magnetic switch connected to the first capacitor, and a peaking capacitor connected in parallel to the first capacitor through the first magnetic switch and to the main discharge electrodes. An interval between start timings of the corona discharge and the main discharge is 30 ns to 60 ns inclusive.

Abstract: A gas sensor includes a wiring board having an opening, a sensor element disposed within the opening and having a detection section and a heater section, and a plurality of electricity conducting members each of which has a first end portion joined to the wiring board and a second end portion joined to the sensor element and which establish electrical connection between the wiring board and the sensor element. The plurality of electricity conducting members fixedly suspend the sensor element within the opening. At least one of the electricity conducting members is a particular electricity conducting member having a plate-like shape, and the particular electricity conducting member includes at least one bent portion between the second end portion joined to the sensor element and the first end portion joined to the wiring board, the bent portion being bent in a thickness direction of the particular electricity conducting member.

Abstract: A saw blade includes a group A (group A1 [=straight tooth+the odd number of set teeth]+group A2 [=straight tooth+the even number of set teeth]) and a group B (group B1 [=straight tooth+the odd number of set teeth having opposite set-bending sides to those in the group A1]+group B2 [=straight tooth+the even number of set teeth having opposite set-bending sides to those in the group A2]). Wide and narrow set teeth are arranged so that a max/min ratio of the number of pitches between the narrow set teeth having identical set-bending side and set width is 1.8 or less, and a max/min ratio of the number of pitches between the wide set teeth having identical set-bending side set width is 2.7 or less.
