Multiple small conductive and flexible hollow rings, each of which is made from a pliable material, provide a flexible connection medium for use between a substrate and a microelectronic device package. Each ring is formed to have at least one protuberance on the a ring's exterior surface. The protuberance has an apex or point, which when placed against a surface, will scrub or scrape the surface as the ring is compressed by a force acting on the ring radially. By scrubbing a contact surface with the apex, surface contaminants and layered material that might interfere with electrical signals can be removed.

A display apparatus comprises transparent display elements arranged on a transparent substrate, a display panel DP whose display image can be observed from either side, a pair of liquid crystal shutter means 2as and 2bs disposed in such a manner as to sandwich the display panel DP, display control means 13 and 15 for displaying, on the display panel, a mirror image of an image to be displayed in every other frame, and liquid crystal shutter control means 14 for opening and closing the pair of liquid crystal shutter means in synchronism with the operation of the display control means such that they do not open simultaneously in each frame scan. The pair of liquid crystal shutter means are opened and closed such that the mirror image can be observed as a regular image on one side of the display panel DP. Image information displayed on the display panel can be viewed simultaneously from both the front surface and the back surface of the display panel.

The present invention provides a planer acoustic transducer including a vibrating diaphragm including a spiral voice coil provided on both surfaces or on one surface of an insulating base film; and a permanent magnet corresponding to the voice coil, wherein, in the vibrating diaphragm, the spiral voice coil is formed by applying a wire conductor, in a coil pattern, onto a sheet-like substrate having an adhesive layer on at least one surface thereof. Alternatively, at least a portion of the vibrating diaphragm, which portion corresponds to the loop of a first or second vibration mode, is reinforced with a rigidity-imparting member; the substrate of the vibrating diaphragm is formed of a resin foam; or the voice coil is formed three-dimensionally.

Plural unit heads are disposed in a paper conveyance direction, and recording head units are configured and disposed in a staggered manner. Head recovery devices are disposed as positions avoiding the locus of splattering of ink droplets from the unit heads. The recording head units can record an image across the entire width of a sheet of paper, and it is not necessary to move the recording head units in the paper width direction. Dummy jetting can be conducted at gap regions between two sheets of paper in an image recording section. The plural unit heads are unitized.
摘要:
Ink in a subtank is sent to an ink circulation path via an ink supply path, and is further returned from the ink circulation path to the subtank via an ink return path. Moreover, the ink is sent from a main tank to the subtank and returned to the main tank from the subtank. Because the ink is circulated not only between the subtank and recording heads but also between the main tank and the subtank, the ink is stably supplied to the recording heads.

The objective of this invention is to reduce the layout area while guaranteeing data retention stability in a static type semiconductor memory cell. This SRAM cell is constituted with two MOS transistors 10 and 12 and one inverter circuit 14. The source terminal of PMOS transistor 10 is connected to bit line (BL), the drain terminal is connected to data storage node (Na), and the gate terminal is connected to word line (WL). The source tenninal of NMOS transistor 12 is connected to a supply voltage terminal that provides low-level reference potential VSS (for example, zero volts), the drain terminal is connected to data storage node (Na), and the gate terminal is connected to the output terminal o inverter circuit 14. The input terminal of inverter circuit 14 is connected to data storage node (Na).

The ATM apparatus comprises line interface units connected to communication lines and processing an Asynchronous Transfer Mode (ATM) cell; each of the line interface units comprises: a physical line termination unit; an ATM processing unit; and an AAL statistical information collection unit for taking in cell flow between the physical line termination unit and the ATM processing unit and the collection of AAL-level statistical information.
摘要:
Making use of a digital acoustic signal processing apparatus arranged by employing memory device for storing a digital acoustic signal, acoustic frequency feature enhancing device for enhancing an acoustic frequency feature, and low-speed sound reproducing device for changing a speed of the stored voice to reproduce this voice as a low speed into a hearing aid and an appliance with an acoustic output, a hearing function difficulty due to an age is aided in utilization of audio output appliances such as a hearing aid, television receiver, and a telephone receiver. After the voice has been stored in the memory device, a process for enhancing the frequency characteristic in order to fit the frequency characteristic to the individual hearing characteristic and the voice reproducing environment is carried out and thereafter represented to the user. The user can repeatedly listen the voice stored in the memory device with employment of control device for controlling the voice reproducing operation. Furthermore, since a process for expanding a time scale during a sound reproducing operation is carried out, the voice can be represented at the low speed. Since the voice whose frequency characteristic has been enhanced can be represented at the low speed in order that either an individual hearing ability, or an apparatus is fitted to a using environment, hearing articulation can be improved with respect to such a hearing, the frequency resolution and the time resolution are simultaneously deteriorated.
摘要:
A circuit designing apparatus of an interactive type which enables a simplified and high-speed circuit design process while largely reducing a burden on a designer, having a speed analyzing unit for conducting a delay computation for each wiring path on a circuit to be designed and a display control unit for displaying a result of the delay computation by the speed analyzing unit on a display unit. When the speed analyzing unit conducts a delay computation, a delay value of each logic component forming the circuit that is an object of the design is set and altered according to a dullness of a signal waveform inputted to the logic component. The circuit designing apparatus of an interactive type may be applied to a system for conducting a circuit design of an integrated circuit such as an LSI or the like or a printed circuit board.
