Abstract: Provided is a transmitter for musical instrument and a mode switching method thereof. A transmitter for musical instrument which is mounted on an electric guitar determines the electric guitar is in a not-in-use state when a continuation time in which a square sum of accelerations output from a three-axis acceleration sensor is smaller than a power-saving threshold value is longer than a power-saving transition time, and the transmitter transitions from a normal mode to an energy-saving mode. On the other hand, when the accelerations in the energy-saving mode becomes equal to or greater than a release threshold value from a state of being smaller than the release threshold value or becomes equal to or smaller than the release threshold value from a state of being greater than the release threshold value, the electric guitar is returned from the energy-saving mode to the normal mode.

Abstract: A reflectance measurement part measures the reflectance of a back surface of a semiconductor wafer. An imaging parameter of a camera is adjusted based on the measured reflectance. The imaging parameter includes exposure time and sensitivity of the camera. The camera with the adjusted imaging parameter images the back surface of the semiconductor wafer to determine the presence or absence of a flaw from the obtained image data. The camera is able to perform appropriate imaging in accordance with the reflectance of the back surface of the semiconductor wafer. Thus, a flaw in the back surface of the semiconductor wafer is detected with reliability even if the reflectance of the back surface is varied due to the deposition of a thin film on the back surface.

Abstract: This leaning vehicle that turns in a leaning posture and has a leaning frame structure made of a material containing fiber-reinforced resin can achieve weight reduction and help reduce changes in ride quality. The vehicle includes a rear structure that leans to the left during a left turn and leans to the right during a right turn with respect to the left-right direction of the vehicle, and is made of a material containing carbon-fiber-reinforced resin, and a leaning frame structure damage notification unit that, when the rear structure receives an impact caused by a fall of the vehicle in the left direction or the right direction, and the impact damages a non-visible part of the rear structure, makes a notification of the damage.

Abstract: A culture container (1) having a guide thread (31) and a plurality of cells (32) that is capable of culturing a regenerative hair follicle germ (30), wherein the culture container (1) is equipped with a first recess (10) and a second recess (20) and the second recess (20) has a second bottom (22) where the guide thread (31) can be positioned in the center of an opening (23) and a method for producing a regenerative hair follicle germ that includes a step for aggregating a cell population including epithelial cells (32a) within the second recess (20) of the culture container (1), a step for aggregating a cell population including mesenchymal cells (32b) within the second recess (20), a step for inserting the guide thread (31) into the second recess (20), and a step for culturing the cell population including epithelial cells (32a) and the mesenchymal cells (32b).

Abstract: A desired image is printed in a non-contact state on a print object surface with a flyable printer in which a printing device is mounted in a flying object. The printer includes a flying object having a body part, a controller, and a drive part; and a print head, mounted in the flying object, to print a desired image in a non-contact state, on a print object which the flying object has approached. The print head is driven while a gap is maintained at a predetermined value by bringing a gap adjustment part attached to the body part of the flying object into contact with the print object or by accurate control of the drive part. It is possible to print a desired image in good image quality regardless of the state of the surface of the print object.

Abstract: A gas detection system includes a sensor unit that outputs a signal corresponding to a concentration of a specific gas, a concentration unit having therein an adsorbent that adsorbs a gas to be detected, a supply unit capable of supplying a sample gas and a purge gas to the concentration unit, a heater capable of heating the adsorbent, and a control unit. The control unit controls the supply unit so that the sample gas passes through the concentration unit, and then controls the supply unit so that the purge gas passes through the concentration unit while controlling the heater so that a temperature of the adsorbent increases.
