摘要:
An aluminum heat exchanger is made from flat aluminum tubes formed with side edge projections having engaging surfaces and coated with brazing material on the outside surface but not on the inside surface of the tube or the projections. The opposite ends of the tubes are inserted into flat tube insertion holes in opposed header tanks which have a brazing material coated on the peripheral surface of the tank, so that, during brazing of the assembled heat exchanger components, brazing material flows from the header tanks to the engaging surfaces of the flat tubes.

A prismatic battery includes an electrode assembly including: a positive electrode including a belt-shaped positive electrode core member and a positive electrode active material layer formed on both surfaces thereof; a negative electrode including a belt-shaped negative electrode core member and a negative electrode active material layer formed on both surfaces thereof; and a belt-shaped separator. The electrode assembly is formed by winding the positive electrode, the negative electrode, and the separator in the longitudinal directions thereof. The negative electrode has, in an end portion thereof from which winding is started, a one-sided active material layer portion in which the negative electrode active material layer is provided only on one surface of the negative core member. The one-sided active material layer portion terminates at a predetermined position between positions at which the negative electrode is folded for the second time and for the third time.

A joint structure of a header tank and a connector in a heat exchanger includes a header tank (1) including a plate wall (1c) formed with a first communication hole (1a). The joint structure includes a block-shaped connector (2) having a second communication hole (2b) positioned to the first communication hole (1a) and joined to the header tank (1). The first communication hole (1a) is smaller than the second communication hole (2b). The first communication hole (1a) has therearound a periphery (1b) caulked and fixed on an inner peripheral surface of the second communication hole (2a) by burring formation.

A heat exchanger comprises outer fins; a plurality of tubes arranged alternately with the outer fins; and header tanks receiving open ends of the tubes for communication with the tubes. The header tanks each comprise a first member and a second member which are combined to each other. The first member has tube insertion slots into which the open ends of the tubes are inserted, the second member does not have the tube insertion slots. The first member is either a core material having no brazing material layers on outer and inner peripheral surfaces thereof, or a core material having a brazing material layer on an outer peripheral surface thereof but having no brazing material layer on an inner peripheral surface thereof. The second member is brazed to the outer or inner peripheral surface of the first member having no brazing material layer thereon.

Instinctive operation of editing parameters of waveform is provided. Tabs 38, 40 and 42 are displayed on a display screen 14 to show existence of parameter edit screen layers of different combinations of characters, waveforms and channels. If one of the tabs are selected the display is switched to show the corresponding parameter edit screen layer. Channel characters or waveforms are displayed on the tabs 38, 40 and 42 and are changed dynamically according to the setting so that a user can easily realize setting outlines of the respective channels at a glance.
摘要:
A pulse delay circuit induces lager jitter to faster input reference pulse trains than before. A buffer receives a reference pulse train and provides non-inverted and inverted pulses. Low pass filters (LPF) and comparators receive the non-inverted and inverted pulses from the buffer and provide pulses having delayed leading and trailing edges. Dividers divide the delayed pulses by 2 to produce the respective pulse trains having a half frequency. An XOR gate produces an exclusive OR of the delayed and divided pulse trains to provide a pulse train having delayed leading and/or trailing edges relative to the reference pulse train. If the delays by the LPFs and comparators are changed, the output pulses from the XOR gate have jitter.

A jitter inducing circuit receives a reference pulse train and induces desired amounts of jitter to the rising and/or falling edges of the pulses. First and second delay blocks 16 and 18 alternately delay the selected edge or edges of the provided reference pulse train interval by preset delay times for every interval. A signal composer 46 composes the outputs of the first and second delay blocks 16 and 18. A delay time setup circuit controls the delay times of the delay blocks 16 and 18. The delay times may change for each interval as a function of time so as to trace a desired function such as a sinusoidal or triangular function.

The one-sided active material layer portion terminates at a predetermined position between positions at which the negative electrode is folded for the second time and for the third time.
摘要:
An electronic instrument displays commands and arguments and their description related to specific user operations of an electronic instrument. A command help bar is displayed in a window with the command help bar displaying a command and associated argument and a description of the command and argument as a function of user defined operations of the electronic instrument using operation means. The user entered value is used as the argument, which allows the user to easily understand a specific description. The user may access additional help windows that displays information on a detailed explanation of the description method (syntax) of the displayed command and a programming example. The description of the command and argument including the specific setting value may be copied and pasted into a program file in a programming widow that is displayed at the same time, which enhances programming efficiency.
摘要:
Delays induced to leading and trailing edges of an input pulse train are updated faster than before. First and second delay paths receive delay data for inducing delays to leading edges and/or trailing edges of an input pulse train. An OR circuit combines the outputs of the delay paths. First and second gates receive the input pulse train and selectively provide the input pulse train to the first and second delay paths independent of the edge position of the input pulse train. A delay time setup circuit generates a CTRL signal for controlling the first and second gates and the loading of the delay data to the first and second delay path. The CTRL signal causes the gates to selectively switch the input pulse train from one delay path to another while the delay data is selectively loaded in the delay path not receiving the input pulse train.
