Abstract: Non-steroidal anti-inflammatory drugs proved to be effective drugs for combating and preventing asthma if administered by inhalation. Useful are for instance acetylsalicylic acid, and indomethacin, and ketoprofen, and tenoxicam. Suitable pharmaceutical compositions for inhalation are aerosols with a particle size of from 0.5  mu m to 7  mu m which enter the compartments of the lungs. Aqueous or aqueous-organic solutions or suspensions can be nebulized in combination with propelling agents, or mixtures of powders with microfine drugs can be administered using inhalers. These pharmaceutical compositions may comprise appropriate additives, in order to improve their relevant pharmaceutical properties.

Title: Camera apparatus
Inventor: ISHIZUKA SHIGEKI
IPC: G02B27/64
Filed: 1993-01-27
Granted: 2002-06-25
Abstract: A camera shake correcting apparatus includes a variable angular prism assembly, a microcomputer to produce signals for driving the variable angular prism assembly, prism actuators, vertical angle sensors, angular velocity sensors for detecting an angular velocity caused by the camera shaking, and damping coils. The variable angular prism assembly is driven by a signal obtained by subtracting detected results of the vertical angle sensors from detected results of the angular velocity sensors. A damping coil is used to produce rotational angular velocity signals so that a nonlinearity of the prism can be alleviated. The phase margin of the servo characteristic of the prism drive system is increased, so that the camera shake correcting apparatus can be generally independent of variations in values and dimensions that occur in mass-production manufacturing operations and free of dependency on temperature characteristics.
