This invention relates to a novel influenza vaccine comprising a complex of HANA antigen and an MDP derivative.The novel vaccine is prepared by mixing an influenza HANA antigen and at least one MDP derivative in a suitable medium; solubilizing the resulting mixture with a surface active agent capable of being removed by dialysis, the solubilization being conducted in the presence or absence of cholesterol, lecithin and dicetyl phosphate or a mixture thereof; and then removing the surface active agent therefrom by dialysis to obtain an influenza vaccine comprising artificial vesicle-like particles of a complex of HANA antigen and MDP derivative, where the MDP derivative forms a membrane of the particle (corresponding to the lipid membrane of natural influenza virus particle) on the surface of which there exists the HANA antigen being bonded to the MDP derivative so as to form the complex. Thus, said artificial vesicle-like particle of the HANA antigen-MDP derivative complex has nearly the same particle size and shape as the natural influenza virus particle.The novel vaccine has an improved immunogenicity compared with the conventional vaccine.

摘要:
A vehicle air conditioning apparatus is provided that can prevent temperature variations of the air after the heat exchange in a radiator to reliably control the temperature of the air supplied to the vehicle interior. During the heating operation and the heating and dehumidifying operation, target degree of supercooling SCt when target air-blowing temperature TAO is a predetermined temperature or higher is set to SCt1 that is greater than SCt2 when the target air-blowing temperature TAO is lower than the predetermined temperature. When amount of air Ga supplied from indoor fan 12 is lower than a predetermined value, the target degree of supercooling SCt is corrected, which is set such that the degree of supercooling is lower than target degree of supercooling corrected when the amount of air Ga supplied from the indoor fan 12 is a predetermined value or higher.

A particle beam irradiation apparatus includes a beam scanning indication unit which two-dimensionally indicates a position of a particle beam in series for each of slices obtained by dividing an affected area to be irradiated in an axial direction of the particle beam, a beam scanning unit which two-dimensionally scans the particle beam based on an indication signal from the beam scanning indication unit, a phosphor film which is provided between the beam scanning unit and a patient and emits light in an amount corresponding to a particle dose of the particle beam transmitting therethrough, an imaging unit which images the phosphor film for each of the slices, and a display unit which obtains an irradiation dose distribution of each of the slices from image data imaged by the imaging unit and displays the obtained irradiation dose distribution associated with a scanning position of the particle beam.
摘要:
A voltage polarity determination circuit includes an integration circuit, a switch, and a time measurement circuit. The integration circuit includes an operational amplifier circuit having an input offset voltage which is larger than the maximum value of a voltage input to the integration circuit or smaller than the minimum value of the input voltage of the integration circuit. The switch switches the input voltage of the integration circuit between a voltage whose polarity is to be determined and a reference voltage. The time measurement circuit measures a time interval which it takes for the output voltage of the integration circuit to reach a set voltage, and based on the result of the measurement, determines the polarity of the input voltage of the integration circuit.
摘要:
When a controller transmits a clock pulse of a positive phase as a first transmit signal (a) and a clock pulse of an opposite phase as a second transmit signal (b), the controller modulates the “H” pulse of the second transmit signal to a signal advanced by time of td1 relative to the “L” pulse of the first transmit signal when the logic of transmit data is “1”, and to a signal advanced by time of td2 relative thereto when the logic of transit data is “0” and transmits the modulated signal. A data carrier device detects the change of the delay time of the second transmit signal by using a clock extracted from the first transmit signal to demodulate data (e).
