Abstract: Motherboard 10M receives a voltage at post 14P from an off-board power source. Buried conductive layer 10B selectively distributes this electrical power to component sites 10S. Post bore 14 penetrates through local electrodes 12U and 12L into the motherboard for exposing post contact regions 14U and 14L and post contact region 14B in the buried layer. Connector post 14P is positioned within the post bore. Post bore conductor 14C within the post bore establishes electrical continuity from the connector post to the buried layer. The post bore conductor also establishes electrical continuity from the connector post to post contact regions 14U and 14L in the local electrodes. Auxiliary bore 16 proximate the post bore penetrates into the motherboard for exposing auxiliary contact regions 16U and 16L in the local electrodes, and auxiliary contact region 16B in the buried layer. Auxiliary bore conductor 16C within the auxiliary bore establishes electrical continuity along the auxiliary bore.

Abstract: An LED printer 21, after power-on, take steps a1 to a6 for preparation and then steps a7 to a9 for printing operation, as shown in FIG. 28. In controlling the printing operation at step a9, the temperature of a fixing unit 46 is detected by a thermistor or the like. Collection of these various data is accomplished by providing a step for counting the number of executions of the operation in the operation executed every one-millisecond and by converting the number of executions thus counted into an elapsed time. The configuration of the processing apparatus is thereby remarkably reduced in size.

Abstract: A method of manufacturing an electroacoustic transducer which is not changed in its characteristic by heat caused by reflow soldering even if a coil is made of a general-purpose wire. The method of manufacturing the electroacoustic transducer including a magnetic driving portion composed of a core provided upright on a base and a coil wound around the core, comprises setting a height of the coil lower by a height, which corresponds to thermal expansion of the coil in reflow soldering, then subjecting the coil to heat processing to thermally expand the coil so that the height of the coil is set to an optimum height.

The sheet feed mechanism comprises a drive shaft, a plurality of driving rollers rotatably mounted on the drive shaft for feeding a sheet, such as a slip, and a single driven roller rotatably disposed so as to press the sheet against the driving rollers. The driven roller has a working surface for pressing the sheet against the driving rollers, corresponding to the plurality of driving rollers.

Abstract: A printing apparatus comprises a CPU 1, an image formation part 9, an interface 7 for communicating with an external host apparatus 19, an operation panel 8 which includes an operation switch and the like, etc., and a power cutoff circuit 12 which operates in response to an instruction which is expressed by a power save signal 17. The printing apparatus also comprises a voltage monitoring circuit 15 for monitoring a signal level change of a host side signal, such as a strobe signal, which is supplied from the external host apparatus 19. When the voltage level of the host signal is intermediate between a first reference voltage V1 and a second reference voltage V2, the voltage monitoring circuit 18 judges that power supply to the external host apparatus 19 is cut off.

Abstract: The present invention is to provide a small-sized sound generator capable of simplifying the structures of terminals, facilitating surface mounting, and setting a sound emitting hole in an arbitrary direction. The small-sized sound generator includes a converting means housed in a housing for converting an electric signal into sound or oscillation, wherein conductors each having an arbitrary pattern are disposed on the surfaces of the housing so as to form terminals integrally with the housing.

Abstract: A printing apparatus comprises a main control circuit 1, an image forming section 10, an interface 8 for communicating with an external host system 9, and an operation panel 20 including operating switches. The apparatus further comprises power cutoff circuits 32 and 33 for interrupting a power supply to the image forming section 10 in response to a command from the main control circuit 1. In the case where a signal input is applied from the operation panel 20 for designating the power saving mode while the printing data is being transmitted from the external host system 9, the transmission data from the external host system 9 are all received and discharged. The power saving mode is started after discharging the data. An erroneous operation can thus be prevented in starting or canceling the power saving mode.

Abstract: Mother board 10M provides a flexible circuit component layout for computer system 10 within housing 10H. The mother board accommodates system component options such as an add-on card 12C or a disk drive bay 10D. Memory module footprint sites 14A-F within memory region 14 are defined on the mother board. Footprints designated in the layout receive components which provide the option flexibility of mother board 10M. Memory module connectors are to be emplaced within the memory region depending on the space requirements of component options. The M memory connectors may be arranged in any configuration selected from a set of multiple possible configurations permitted by M module connectors of T types emplaced in F footprint sites (where F>M). F minus M footprint sites remain vacant without a module connector emplaced therein. These vacant sites provide empty spaces which may be "shuffled around" to accommodate the various system component options.

Abstract: Computer apparatus 10 has a convective air flow therethrough for removing heat generated by the IC chips on circuit boards 12H, 12M, and 12L and by other computer components within housing 10H. The housing confines the convective air flow, and has elongated I/O openings 10E therethrough for accommodating I/O connections to the circuit boards. The circuit boards are mounted within the housing in an adjacent parallel relationship forming air flow channels therebetween. Each circuit board has a housing end 12P proximate the I/O openings in the housing and an interior end 12D distant from the housing. A mounting bracket 14 is fastened to each circuit board at the housing end and is secured to the housing to cover the I/O openings. Air vent apertures 16 in the mounting brackets provide air flow communication through the mounting brackets and the I/O openings for directing a portion of the convective air flow through the channel over the adjacent circuit boards.

Abstract: An automated method for winding a coil of an electroacoustic transducer utilizes a support member that has a frusto-conical projection for receiving an outer pole tip. The frusto-conical configuration assures that, upon completion of a coil winding about the pole, there is an exposed recess around the periphery of the pole tip. This is accompanied by an end surface of the winding being coplanar with the corresponding end surface of the pole tip. Maximized performance for the transducer may then be realized.
