Abstract: An electric work machine has less size increase. An electric work machine includes a power supply device, a first electric component, a second electric component, a first electric wire connecting the power supply device and the first electric component, a second electric wire connecting the power supply device and the second electric component, a power supply housing accommodating the power supply device, a first housing accommodating the first electric component, a second housing accommodating the second electric component, and a sheath accommodating the first electric wire and the second electric wire. The sheath has a first end located inside the power supply housing, and a second end located inside the first housing. The second electric wire extending from the sheath is placed in the second housing.

Abstract: The present inventors succeeded in culturing thick three-dimensional muscle tissue in which the muscle fibers are oriented in the same direction by providing channels for transporting a culture medium inside a hydrogel containing skeletal myoblasts. The three-dimensional muscle tissue produced according to the invention is expected to have a steak-like texture. Additionally, in regenerative medicine applications, damage in extensive and thick muscle tissue is expected to be healed with a single treatment by using thick three-dimensional muscle tissue.

Abstract: An indicator lamp of the present invention includes a lamp body, a light source unit disposed inside the lamp body, and a light transmissive resin member disposed at a position for transmitting light that is emitted from the light source unit and for outputting the light from the lamp body. The light source unit emits red light having a maximum value of light intensity at a wavelength of 600 nm or longer and 700 nm or shorter. The light transmissive resin member has an L* value of 35 or less, a transmittance of light having a wavelength of 675 nm of 90% or greater and a total light transmittance of 5% or greater in the state in which an optical path length of transmitting light is 2 mm. This configuration provides an indicator lamp with excellent design that shows its presence by showing a red chromatic tone when a light source is turned on and that shows a black color tone when the light source is turned off.

Abstract: Provided is a power semiconductor device including a signal terminal and a power semiconductor element. The power semiconductor element is arranged on a substrate. The signal terminal includes a main body portion and a joint portion, and a part of the signal terminal is held by a terminal block. The joint portion includes a distal end portion and a base portion. The distal end portion includes a pad portion that is exposed from the terminal block and connected to a signal line. The base portion includes a thin portion in which a thickness in a vertical direction is set to be smaller than that of the pad portion. The thin portion has an upper surface that is formed at a position lower than an upper surface of the pad portion and is covered with a resin material forming the terminal block.

Abstract: In an electric power tool, a stator of a motor is housed in a grip and the stator is located coaxial to the grip. An electric wire for the motor is passed through a ferrite core. Further, the ferrite core is located inside an outer peripheral surface of the stator in a radial direction.

Abstract: A power tool, for example, a portable circular saw, includes a fan, a motor configured to rotate the fan, an output part or shaft driven by the motor, a motor housing that houses the motor, a grip housing connected to the motor housing, a trigger associated with the grip housing, and a brake member configured to brake a rotation of the motor, the brake member being mounted inside the grip housing. The brake member may be a resistive element of a rheostatic braking system. The housing and fan are configured such that cooling air is directed to cool the brake member.

Abstract: A molding module 2 includes: a mold 11 including a lower mold 10 and an upper mold 7 facing each other; a cavity 12 provided in the lower mold; a bottom member 9 forming the inner bottom surface 14 of the cavity; a circumferential member 8 forming the inner circumferential surface 13 of the cavity; a mold-driving mechanism for opening and closing the mold 11; a lower base 3; a support member 4 vertically provided on the lower base; an upper base 5 provided in the upper portion of the support member; and an elevating platen 6 mounted on the middle portion of the support member in a vertically moveable manner.
