Abstract: Optical encoder includes a light source, a reflector, and a light receiver. Reflector has a plurality of reflection areas that include M-code areas and reflects a light from light source by one or more areas, corresponding to n-bits, of M-code areas. Light receiver receives a reflection light from reflector to perform a photoelectric conversion on reflection light. M-code areas has a first face corresponding to first code information and a second face corresponding to second code information and having an inclination structure different from that of first face. Light receiver has first and second light-receiving groups. First light-receiving group includes a plurality of first light-receiving elements receiving reflection light reflected from first face. Second light-receiving group includes a plurality of second light-receiving elements receiving reflection light reflected from second face. Positions of first light-receiving elements and positions of second light-receiving elements are shifted from each other in one direction.

Abstract: A lighting system includes a light source unit and a light-distributing member. The light source unit includes a laser light source. The light-distributing member has the function of reflecting incident light that has been emitted as a beam of light from the light source unit toward a target space. The light-distributing member transforms the incident light into lighting light having a different light distribution property from the incident light and distributes the lighting light over the target space.

Abstract: A secondary battery includes a positive plate, a negative plate, a porous separator, and a non-aqueous electrolyte. In the secondary battery, lithium metal deposits on the negative plate during charging, and lithium metal dissolves in the non-aqueous electrolyte during discharge. The secondary battery includes: a spacer interposed between at least one of electrode plates of the negative plate and the positive plate and the separator to form a space between the electrode plate and the separator; and a low porosity portion that has a smaller porosity than the separator and that is fitted into the separator in an area where the separator and the spacer overlap when viewed from a laminating direction of the separator and the electrode plate.

Abstract: A positioning equipment includes a camera, a lens disposed in an imaging direction of the camera, a light synthesis unit, and an arithmetic equipment. The light synthesis unit is disposed between a bonding head and a stage when a first component and a second component are positioned, synthesizes light incident from the bonding head side and light incident from the stage side, and reflects the synthesized light to the lens side. The camera images a camera image based on light incident via the lens. The arithmetic equipment obtains a position correction amount between the first component and the second component based on the camera image.

Abstract: A method for manufacturing a mounting board includes a first outer shape position acquisition step, a feature portion position acquisition step, a calculation step, a holding step, a second outer shape position acquisition step, and a mounting step. In the first outer shape position acquisition step, a first outer shape position of a component is acquired. In the feature portion position acquisition step, a position of a feature portion is acquired. In the calculation step, a deviation amount of the position of the feature portion with respect to the first outer shape position is calculated. In the second outer shape position acquisition step, a second outer shape position of the component is acquired. In the mounting step, the feature portion of the component is mounted to be positioned on a target position of a board based on the second outer shape position and the deviation amount.
