  • Patent number: 9894751
    Abstract: First and second semiconductor devices and first and second bypass circuits are mounted on a printed wiring board. The first bypass circuit and the second bypass circuit are provided closer to the first semiconductor device and to the second semiconductor device, respectively. The first bypass circuit has one end connected to a power plane through a first power supply via and the other end connected to a ground plane through a first ground via. The second bypass circuit has one end connected to the power plane through a second power supply via and the other end connected to the ground plane through a second ground via. The ground plane has a slit between the connecting portions of the first and second ground vias to increase the impedance between the connecting portions of the first and the second ground vias. Thus, jitters caused by power supply noise can be reduced.

  • Publication number: 20180035493
    Abstract: A heat generating apparatus includes a rotary shaft, a heat generating drum, a plurality of permanent magnets, a magnet holding ring, a switching mechanism, and a heat recovery system. The magnets are arrayed in a circumferential direction along the circumference of the rotary shaft throughout the whole circumference such that magnetic pole arrangements of circumferentially adjacent ones of the permanent magnets are opposite to each other. The magnet holding ring holds the magnets. The switching mechanism switches between a state to generate magnetic circuits between the magnets and the heat generating drum and a state to generate no magnetic circuits between the magnets and the heat generating drum. The heat recovery system collects heat generated in the heat generating drum. Thereby, thermal energy can be recovered from the kinetic energy of the rotary shaft efficiently.

  • Patent number: 9772914
    Abstract: A processing apparatus includes a precursor detection unit that detects a precursor event indicating a precursor that a target process cannot be executed by a process unit, and a control unit that sends a preparation request to a substitution processing apparatus when the precursor detection unit detects the precursor event in which the preparation request requests the substitution processing apparatus being a ready state for starting a substitution processing. The control unit sends a termination request to the substitution processing apparatus when a predetermined condition is satisfied after the control unit sends the preparation request, in which the termination request requests the substitution processing apparatus terminating the ready state.

Protrusions are provided on an end face of the drum at regular intervals entirely in the circumferential direction. Electricity generating coils are provided in a non-rotating part of a vehicle at regular intervals entirely in the circumferential direction such that the electricity generating coils face the regions of the end face of the drum.

  • Patent number: 9538634
    Abstract: A printed circuit board (e.g., 103) includes capacitor elements (e.g., 121 and 122). The capacitor element (e.g., 121) returns a common mode current included in a signal output from a signal output terminal (e.g., 111) of a semiconductor element (e.g., 102), to a ground terminal (e.g., 113) of the semiconductor element (e.g., 102). The capacitor element (e.g., 122) returns a common mode current included in a signal output from a signal output terminal (e.g., 112) of the semiconductor element (e.g., 102), to the ground terminal (e.g., 113) of the semiconductor element (e.g., 102). The capacitor elements (e.g., 121 and 122) are arranged such that the mutual inductance between a parasitic inductance of the capacitor element (e.g., 121) and a parasitic inductance of the capacitor element (e.g., 122) for the common mode currents is a negative value. Accordingly, the effective inductances of the first and second capacitor elements for the common mode currents are reduced, which suppresses radiation noise.

    Abstract: A braking actuator uses a single cylinder without using a spring to achieve a 3-position operation. A partition plate and an intermediate check plate are affixed within a cylinder at suitable intervals in the axial direction. Inserted movably in the axial direction of the cylinder are a first piston disposed between a pressing lid and the intermediate check plate, a second piston disposed between the intermediate check plate and the partition plate, and a third piston disposed between the partition plate and a pressing lid. A rod which is axially movable within the cylinder has a base end attached to the third piston and a tip end which extends outside from the cylinder through the partition plate, the second piston, the intermediate check plate, the first piston, and the pressing lid. A stopper affixed to a middle portion of the rod moves the first piston or the second piston.
