Abstract: The components of a gas mixture are separated by pressure swing adsorption in a plurality of adsorption vessels. In the first step of the half-cycle adsorption takes place in a first bed while the second bed undergoes countercurrent desorption. At the end of the first step the first bed is vented countercurrently and the first and second beds undergo, as a first bed equalization step, outlet-to-outlet equalization or outlet to both inlet and outlet equalization. The vent step may precede or be concurrent with the first bed equalization step.In a second equalization step the beds simultaneously undergo inlet-to-inlet andoutlet-to-outlet equalization. The second bed is then further pressurized with nonadsorbed product gas. The half cycle is then repeated but with the first bed being substituted for the second bed and vice versa.

Filed: 1996-01-16
Granted: 2001-03-06
Abstract: An apparatus for transcutaneously transmitting a power signal to, and communicating first and second information signals with, an implantable device. The apparatus can include an external unit having first power means for generating the power signal; first signalling means for generating the first information signal; first receiving means for receiving the second information signal; and first coupling means for independently coupling the power signal and said first information signal. The apparatus can also include an internal unit having second power means for receiving the power signal; second signalling means for generating the second information signal; second receiving means for receiving the first information signal; and second coupling means for independently coupling the power signal and the second information signal. The first power means transmits the power signal at a power frequency, and the first signalling means can transmit the first information signal at a frequency greater than the power frequency. The first power means may also include a power supply. The second signalling means, too, may transmit the second information signal at a frequency greater than the power frequency. The external unit can include a power converter for converting a power input signal at a first preselected frequency to a power signal at the power frequency; an external coupler for transmitting the power signal, and for communicating the first and second information signals; an external signal conditioner for symmetrically transceiving the first and second information signals; and an external data controller for symmetrically controlling the first and second information signals. The internal unit can include an internal coupler for receiving the power signal and for communicating the first and second information signals; a voltage regulator for converting the first power signal into said second power signal which is provided to the implantable device; an internal signal conditioner for symmetrically transceiving the first and second information signals; and an internal data controller symmetrically controlling the first and second information signals. Symmetrically controlling includes ASK modulation of a data signal upon an RF carrier signal of a preselected carrier frequency, which is presently preferred to be about 8 megaHertz (MHz). The external and internal couplers each can include a primary and secondary tuned circuit, respectively. Each tuned circuit has a resonant frequency which can be, for example, about 160 kiloHertz (kHz). In addition, the first and second signal conditioners can include a first and second frequency-selective filter, respectively. Each frequency-selective filter can have cutoff frequencies of between about 7.9 MHz and 8.1 MHz, with a central frequency of about 8 MHz.

The structure is constructed such that an air intake port is located behind a first headlamp in the engine compartment, an opening of the air intake port is arranged in front of the compartment, and a rotational direction of a first cooling fan of a pair of cooling fans mounted on a rear side of a radiator at substantially the same height is determined such that the air discharged by the first cooling fan is directed away from the air intake port of the engine, and a rotational direction of the second cooling fan of the pair of the cooling fans is determined opposite to the first cooling fan, in which the first cooling fan is closer to the air intake port than the second cooling fan.  Furthermore, air volume discharged by the first cooling fan mounted closer to the air intake port in the pair of the cooling fans is set larger than that of the second cooling fan. Furthermore, rotational directions of a pair of cooling fans mounted on a rear side of a radiator at substantially the same height are determined such that the air discharged by the cooling fans is directed toward a space in the rear side of the other headlamp, and each air volume discharged by the respective cooling fan is set different.

Abstract: A sheet for protecting paint films of automobiles for adhering to the incompletely cured paint films of automobiles comprising two pack urethane paint, the sheet comprising a support and a pressure-sensitive adhesive layer formed thereon, wherein the sheet has a Young's modulus E of at least 75 N/mm2 and a coefficient of flexural stress k represented by the formula k = Eh3 wherein h is a thickness of the support, of 0.035 or less.  The protective sheet can uniformly protect the paint films and easily be peeled and removed therefrom without causing environmental problems and adhesive remaining of the pressure-sensitive adhesive layer.   Even when the sheet is adhered to incompletely cured paint films of automobiles and they are allowed to stand for a long period of time under an outside high temperature in summer, the sheet does not cause the deformation of the paint film and the microdeformations by the deformation of the paint film at the edge portion of the pressure-sensitive adhesive layer.  The protective sheet can be reserved in a roll state without causing the change of form by, for example, a telescope phenomenon.

Abstract: A shovel lifting aid comprises a lever arm pivotally attached to the shovel handle, the opposite end of said lever arm terminating in a curved fork, spanned by a crossbar. The curved fork serves as a fulcrum for the application of foot pressure on the crossbar, which combined with a rearward pull on the shovel handle enables asmooth and comparatively effortless raising of the loaded shovel to hip level. At the top of the lift the lever arm is biased to support the raised load in a "cradled" position, requiring minimal effort by the user. An additional leg may be pivotally attached to the free end of the shovel handle, and enable the hand-free tabling of the raised load. Variations of the invention are suitable for use with lifting poles and other tools.

Title: Method of transforming periodic signal using smoothed spectrogram, method of transforming sound using phasing component and method of analyzing signal using optimum interpolation function
Inventor: MASUDA IKUYO
IPC: G10L25/27
Filed: 1997-07-17
Granted: 2001-11-06
Abstract: At a smoothing spectrogram calculation portion, a triangular interpolation function having a frequency width twice that of the fundamental frequency of a signal is obtained based on information on the fundamental frequency of the signal.  The interpolation function and a spectrum obtained at an adaptive frequency analysis portion are convoluted in the direction of frequency.  Then, using a triangular interpolation function having a time length twice that of a fundamental period, the spectrum interpolated in the frequency direction described above is further interpolated in the temporal direction, in order to produce a smoothed spectrogram having the space between grid points on the time-frequency plane filled with the surface of a bilinear function.  Using the smoothed spectrogram, a speech sound is transformed.  Therefore, the influence of periodicity in the frequency direction and the temporal direction can be reduced.
