Abstract: A multilayer wiring board includes a first dielectric layer, a high-frequency signal line formed on a first surface of the first dielectric layer, a ground layer formed on a second surface of the first dielectric layer, and a second dielectric layer covering part of the ground layer. The high-frequency signal line is electrically connectable to a center conductor of a coaxial structure. The second dielectric layer is spaced from an edge of the first dielectric layer to which the coaxial structure is to be connected, so that a ground exposure portion of the ground layer is exposed on the edge of the first dielectric layer. The ground layer is electrically connectable directly to an outer conductor of the coaxial structure at the ground exposure portion.

Abstract: Provided is a transmission line used to transmit high-frequency electrical signals which can remove a dip-shaped (S21) loss of transmission characteristics due to wall surface resonance, furthermore, can further decrease the size, and can suppress the manufacturing cost at a low level. The transmission line used to transmit high-frequency electrical signals (1) is made up of a signal line (3) used to transmit high-frequency electrical signals which is formed on a front surface (2a) of a dielectric substrate (2), GND electrodes (4) formed outside the signal line (3) and in vicinities of end portions of the front surface (2a), a GND electrode (6) that is electrically connected to the GND electrodes (4) through via holes (5) formed across an entire rear surface (2b) of the dielectric substrate (2), and band-shaped resistors (7) that are formed outside the GND electrodes (4) and in the end portions of the surface (2a) and are electrically connected to the GND electrodes (4).

Abstract: A bed in which a gap between back and leg side-rails is kept constant when a back bottom is raised. A first link and a second link (2, 3) are rotatably supported at lower ends thereof on a frame (1). A coupling (6) is fixed to the base end part of a deck (7), and upper ends of the first and second links (2, 3) are rotatably connected to the coupling (6). An L-shaped rotator (4) is rotatably supported by the frame (1), and one end of a third link (5) is rotatably connected to an upper end (1c) of the rotator (4). The other end of the third link (5) is rotatably connected to the coupling (6). An actuator (13) is supported by the frame (1), and a piston rod (13a) is rotatably connected to a central portion (1b) of the rotator (4). The rotator (4) is turned by an advancing of the piston rod (13a); the relative positions of the fourth, fifth, and sixth links are changed; and the leg side-rail slides along the frame (1).

Abstract: A vibration device, which can generate impressing vibrations and is not easily broken even when a large impact of a drop, etc. is exerted, is provided. A gun-shaped controller 30 includes a barrel 32 and a barrel jacket 34 formed integral and a receiver 36 to a grip 38 are formed integral. A trigger 37 is provided on the underside of the receiver 36. Inside the grip 38 of the gun-shaped controller 30, 2 vibration actuators 40A, 40B are mounted, opposed to each other. Actual shooting sounds are applied to the vibration actuators 40A, 40B to thereby realize realistic vibrations of shooting. The vibration actuators 40A, 40B each includes a coil and a magnet. The coils are secured to the case members, the magnets are swingably mounted on the case members 38, and the movements of the vibrating magnets are restricted by restricting members.

Abstract: A brake apparatus for a moving apparatus driven by a linear motor, to support a headstock. The brake apparatus includes an air cylinder disposed parallel with a travelling direction, a compressor to supply fluid under pressure to the air cylinder, a 2-port solenoid valve disposed on a fluid path connecting from the compressor to the air cylinder, and a controlling device that outputs a signal to open the 2-port solenoid valve during normal operation of the linear motor and controls the 2-port solenoid valve to close when the power supply to the linear motor is interrupted or the linear motor is stopped in an emergency.

Abstract: In a non-contacting fluid coupling device for feeding fluid to a hollow core of a rotating tool, one end of a hollow coupling shaft is attached in fluid communication to the shaft of the rotating tool. The other end of the coupling shaft is received, in a non-contact manner, in a hollow of a coupling main body. The coupling main body has an opening and passage in fluid communication with the hollow coupling shaft to introduce high pressure fluid to the hollow core of the rotating tool. Between the hollow of the coupling main body and the coupling shaft is at least one pressure reduction passage. Downstream of each pressure reduction passage is a pressure reduction chamber having a drain hole to the atmosphere. Downstream of the last pressure reduction chamber is a minute space between the coupling main body and the coupling shaft into which is introduced compressed air that precludes leakage of the fluid further downstream in the coupling device.

Abstract: A spindle device providing a hydraulic system for moving a drawbar in a tool holding direction. The drawbar extends through a spindle shaft and is slidably provided therein. A piston is fixedly connected to the drawbar, and a pressure chamber is defined by the spindle shaft, the drawbar and the piston. Upon application of hydraulic pressure in the pressure chamber, the piston as well as the draw bar are moved in the tool holding direction. In one embodiment, at least one free piston is provided in the pressure chamber for dividing the same into first and second pressure chambers. The hydraulic pressure is applied to the first chamber to urge the free piston toward the second pressure chamber in which a liquid is hermetically accumulated. The liquid pressure within the second pressure chamber is increasable higher than the hydraulic pressure for urging the piston toward the tool holding direction with an increased force.
