Abstract:
A cutting insert has a main body which is provided with an upper surface, a side surface, at least one groove which is formed in the side surface and which extends to the upper surface at one end, and a plurality of split cutting blades which are split by the at least one groove. The upper surface is provided with inclined portions corresponding to the split cutting blades. The distance of respective lower ends of the inclined portions from the corresponding split cutting blades increases toward the centers of the corresponding cutting blades in a plan view. A cutting tool having the cutting insert and a method for cutting a workpiece using the cutting tool are also provided.
Abstract:
A data transfer control device includes an OUT-transfer transmitter circuit which transmits OUT data by driving a serial signal line, a clock-transfer transmitter circuit which transmits a clock signal CLK by driving a serial signal line, a PLL circuit which generates the clock signal CLK, and a power-down setting circuit which sets a power-down mode. In a first power-down mode, the OUT-transfer transmitter circuit is set to the power-down mode, and the clock-transfer transmitter circuit is set to the power-down mode to stop a system clock signal of a target-side data transfer control device. In a second power-down mode, the OUT-transfer transmitter circuit is set to the power-down mode without setting the clock-transfer transmitter circuit to the power-down mode.
Abstract:
A negative electrode element for a lithium-ion secondary battery includes: a negative electrode current collector; and a negative electrode layer that includes an alloying active material layer formed on the negative electrode current collector and a resin layer formed on a surface of the alloying active material layer so as to have an opening that exposes part of the alloying active material layer to a surface of the negative electrode layer. The surface of the alloying active material layer, exposed to the opening, and a surface of the resin layer form a step so that the surface of the resin layer is farther from a surface of the negative electrode current collector than the exposed surface of the alloying active material layer.
Abstract:
A throwaway insert enabling the use of a holder for a long period and having excellent chip evacuation is provided. The throwaway insert is formed in a substantially polygonal plate shape and includes a rake face formed on an upper surface thereof, a relief face formed on a side surface thereof, a main cutting edge formed along a ridge representing an intersection of the rake face and the relief face, which is divided into a plurality of main cutting edge divisions by at least one groove formed on the relief face, and a projection formed so as to protrude from the rake face in correspondence with each of the main cutting edge divisions.
Abstract:
A transfer controller (or a host controller) issues IN tokens to a plurality of USB devices connected to USB and including first and second USB devices. When data including destination information which specifies the second USB device as a destination has been received in response to an IN token issued to the first USB device, the transfer controller issues an OUT token to the second USB device and transmits the received data from the first USB device to the second USB device. The transfer controller issues an IN token to at least one of the USB devices which has declared itself to be a local area network (LAN) node.
Abstract:
A transmitter circuit including: a current driver which current-drives differential signal lines; and a voltage driver which is electrically disconnected from at least one of the differential signal lines in a normal transfer mode, and is electrically connected to the at least one of the differential signal lines and voltage-drives the at least one of the differential signal lines in a power-down mode. The voltage driver outputs a power-down voltage for setting a receiver circuit to the power-down mode or a wakeup voltage for canceling the power-down mode of the receiver circuit, to the at least one of the differential signal lines. The current driver transmits a power-down command to the receiver circuit by current-driving the differential signal lines in the normal transfer mode.

Abstract:
In a charge pump circuit, the through rate at which a clock signal is fed to charge transfer transistors is changed according to the output voltage. This configuration helps alleviate rush currents at start-up without unduly lowering efficiency.
Abstract:
Ergonimic hand tools according to the present disclosure provides variations in finger relief to accommodate variations in human physiology and an aligning finger handle that aligns the users fingers into a minimum stress position relative to each other and to the thumb.
Abstract:
A buffer is provided with a CBW area (a randomly accessible command storage area) and an EP1 area (data storage area set to FIFO), when a CBW and data are allocated as informations to be transferred through one end point EP1. When a phase switches from a USB command phase (command transport) to a data phase (data transport), the information write area is switched from the CBW area to the EP1 area and OUT data transferred from the host to the end point EP1 is written into the EP1 area. The area switches from the CBW area to the EP1 area on condition that an acknowledgment has returned to the host in the command phase. In case of a toggle missing, area switching does not occur even if ACK is returned.
