Patent JP-H0790225-B2 (JP)
IPC: C02F1/469
Filed: 1990-09-25
Abstract: The present invention provides a method and apparatus for treating electrically conductive fluid. Positive and negative electrodes (1,2) of electrically conductive materials having different electrochemical potentials are spaced apart and electrically isolated from one another so that the only electroconductive connection that develops an electrochemical potential between the electrodes (1,2) is established by fluid to be treated extending between the electrodes. Fluid passing between the electrodes is therefore ionized. Because it has been found that superior effects can be achieved when the fluid is ionized under a voltage only condition, in which there is relatively little current flow through the fluid, an electrical insulator (3) is disposed between the positive and negative electrodes, extending across any shortest direct path therebetween. Thus, the electroconductive connection between the electrodes (1,2), that is established only by the body of fluid to be treated in the apparatus, is established through the fluid along a path that extends around the electrical insulator (3). Such a path, which is longer than any shortest direct path between the electrodes (1,2), defines a relatively long resistive path through the fluid between the electrodes. Accordingly, current flow is inhibited. <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To provide a failure diagnostic device for a hybrid vehicle, which can accurately and easily judge the diagnosis of the failure of an evaporated fuel recovering system and an exhaust gas purifying catalyst while improving performance of fuel consumption. SOLUTION: In a hybrid vehicle, an evaporated fuel recovering system is arranged which is equipped with a fuel tank 31 and a purge passage 37 communicating the fuel tank 31 with a surge tank 25, negative pressure in the inside of the surge tank 25 is introduced to the evaporated fuel recovering system, and the failure of the evaporated fuel recovering system is diagnosed based on pressure change caused by the introduction of the negative pressure. The deterioration of a three-way catalyst is judged based on a reverse ratio A/B being a ratio of rich reverse frequency A to lean reverse frequency B of upstream and downstream side O2 sensors 28, 29.  An engine 1 is basically operated at high efficiency, therefore performance of fuel consumption can be improved, and also the failure of the evaporative fuel recovering system and exhaust gas purifying catalyst can be accurately and easily diagnosed.

Abstract: A system for interconnecting widely separated local area networks (LANs) by means of a wide area network (WAN) utilizes network level facilities to establish a connection through the wide area network and to create connection table entries at the WAN access point which allow subsequent data frames to be transmitted through the wide area network without such network level operations. More particularly, the various LANs are combined into search groups, represented by address prefixes, to which LAN-initiated connection requests can be broadcast and which can respond so as to establish the data path connections. This system has the connection flexibility of a prior art router and, at the same time, the low overhead of a prior art bridge. <IMAGE>

Abstract: PURPOSE:To connect an external terminal to a wiring without requiring a facility and a jig by placing leads on a board and composing of a chiplike terminal component. CONSTITUTION:First, a chiplike terminal component 6 is placed on a board 1 by the same device in the same step as that of an electronic component 2, and connected to a wiring 5 on the board 1 by a connecting material 3. Thereafter, it is exposed without covering a part to become an external terminal of the component 6, and a sheath 4 is provided. Since a surface to be connected to the wiring 5 of the component 6 must be electrically conducted with a component to become the external terminal, the entire component 6 is formed of a conductor or electrically short-circuited by a conductor film. Thus, in order to provide the external terminal, the component 6 is used thereby to place by the same step and device as those of a general electronic component, and a surface mounting type hybrid integrated circuit can be easily inexpensively realized.

Abstract: A hearing aid or audio communication system includes an earpiece (10) that can be hidden in the ear canal, and which communicates wirelessly with a remote processor unit, or RPU (16), that enhances audio signals and can be concealed under clothing. Sounds from the environment are picked up by a microphone (12) in the earpiece and sent with other information over a two-way wireless link (17) to the RPU (16). The wireless link (17) uses microwaves for component miniaturization. Furthermore, use of radar technology to implement the wireless link (17), with an RPU (16) interrogator and earpiece (10) transponder, reduces earpiece size and power, as no microwave oscillator is needed in the earpiece (10). Optional secondary wireless link circuitry (19) can be used between the RPU (16) and a cellular telephone system or other sources of information.

Date Nov. 30, 1989.A method of transmitting an audio signal wherein the audio signal is partitioned into successive (in time) blocks by means of time windows, the signal parts contained in the blocks are converted to short-time frequency spectrums by transformation, subsequently the short-time frequency spectrums are coded on the basis of psycho-acoustical masking laws and are transmitted. The received coded signals are decoded, the short-time frequency spectrum signals are brought back into the time domain through re-transformation, and finally the blocks present in the time domain are assembled. Moreover, the blocks are partitioned into sub-blocks and, in case of signal level changes from one block to the other which exceed a predetermined value, the signal parts in the sub-blocks are subjected to a compression prior to transformation and to a complementary expansion after the re-transformation. To improve the signal-to-noise ratio, the signal is amplified and/or attenuated in the sub-blocks during the compression dependent on the average signal powers in the respective sub-blocks.
