Abstract: A work machine includes a power source, a rotation shaft that is rotated by power of the power source, a cutter blade that is rotated by the rotation shaft to cut a plant on the ground, and a housing that houses the cutter blade and has an opening through which the cutter blade is exposed to the ground. The housing has a charging port through which an object to be cut is charged to the cutter blade.

Abstract: A mower (1) comprising: a blade (9) that mows grass; a power generation unit (5) that generates a driving force for rotating the blade (9); a housing (7) that covers the blade (9); and a milling unit (10) that subdivides grass mowed by the blade and discharged from the housing (7).

Abstract: Provided are an analysis device, an analysis method, a program, and a calibration method. The analysis device includes: an obtaining part obtaining an image captured by an image capturing part that captures an image of one or more first markers provided on an estimation target; and a calibration part calibrating a conversion rule from a sensor coordinate system to a segment coordinate system based on the image. A posture of the first marker relative to at least one inertial measurement sensor does not change, and the posture with respect to the image capturing part is recognizable by analyzing the captured image. The calibration part derives the posture of the first marker with respect to the image capturing part, derives a conversion matrix from the sensor coordinate system to a camera coordinate system based on the derived posture, and calibrates the conversion rule by using the derived conversion matrix.

Abstract: To provide a manufacturing method of a field emission cathode, which method exerts no adverse effect on element characteristics at the time when etching is performed with an ion beam. A sacrificial layer 4 made of a thermosetting resin is formed on a gate electrode layer 3. An opening section 5 is formed in the sacrificial layer 4 and the gate electrode layer 3 by irradiating a focused ion beam, and a hole section 6 is formed by etching the insulating layer 2 by using the sacrificial layer 4 and the gate electrode layer 3 as a mask. An emitter electrode 8 is formed in the hole section 6, and the emitter material 7 on the sacrificial layer 4 is removed together with the sacrificial layer 4 on the gate electrode layer 3.

Abstract: In a cell assembling device, an ATM cell assemblage decomposes input signals channel by channel and outputs channel-by-channel signals. At the same time, the cell assemblage generates a write control signal. Further, when one cell of data is written to a buffer, the cell assemblage generates a condition report signal for informing an arbitrating circuit of the channel of the cell. In response, the arbitrating circuit determines a channel to read out on the basis of the amounts of cell data stored in the buffer, and then outputs a read control signal meant for the above channel. On receiving the write control signal, the buffer writes the channel-by-channel signal therein. In response to the read control signal, the buffer outputs the signal of the channel designated by the signal and feeds it to a cell transmission circuit. The transmission circuit adds a cell header to the data output from the buffer to thereby form a cell to be sent.

Abstract: To cascade a network line concentrator and a plurality of terminals, the network connection circuit installed in each of the plurality of terminals forwards first data in a direction from the line concentrator to the neighboring terminal, provides the first data for the terminal, forwards second data in direction from the neighboring terminal to the network line concentrator, and transfers third data from the terminal toward the network line concentrator.
