Title: Process and apparatus for the evaluation of the printing quality of a printed product produced by an offset printing machine
Inventor: OTT HANS
IPC: B41F33/14
Filed: 1984-11-02
Abstract: Printed products and their respective corresponding printing plates are divided into a plurality of image elements. For each image element the surface coverage is determined by photoelectric measurements; a reference reflectance value is then calculated from these measurements, taking into consideration such parameters as the printing characteristic. These reference reflectance values are compared with the actual reflectance values measured on the printed products and the results of the comparison are evaluated to form a quality measure and to calculate control values for the ink feed devices of the printing machine. In this manner, the use of special color measuring strips may be eliminated.

Title: Exposure control mechanism for still video camera
Inventor: OTA YOSHITAKA
IPC: H04N9/73
Filed: 1991-03-05
Granted: 1994-01-05
Abstract: In an exposure control mechanism for a camera, and more particularly for a still video camera which obtains an image signal using an image sensor, a first preliminary exposure is conducted with almost all the center portion of an automatic exposure luminance range exposed to light of the most suitable exposure level. The specific number of pixels obtained through this exposure is limited to within the foregoing middle luminance range. However, since the total number of pixels are known, the total number of pixels saturated with image pick-up signals due to high exposure intensity in the portion recognized as white, and the total number of pixels in the portion recognized as black due to low exposure intensity, can be obtained by distribution data of pixels in an image pick-up screen with regard to the luminance level obtained by the first preliminary exposure. From the numbers of pixels in the portion recognized as white and in the portion recognized as black, the luminance information of the entire image pick-up screen, and rough information about the luminance distribution, are obtained, and a second preliminary exposure condition can be determined based upon the obtained information. Consequently, metering can be completed when preliminary exposure has been conducted twice.

Title: Ultrasonic welder with controlled seal compression
Inventor: HECKARD DAVID P
IPC: B29C65/08
Filed: 1991-06-21
Granted: 1994-04-20
Abstract: A two stage process of ultrasonic welding is disclosed wherein a first stage determines the amount of displacement required to produce a desired compressive force upon a seal or spring. This displacement is sent to a second stage where the desired displacement is achieved through ultrasonic bonding. In an alternative embodiment, the first stage determines the amount of displacement required to achieve non-compressive contact between the gasket (seal) and the component. This displacement is summed with an empirically determined displacement required to obtain a desired compressive force upon the gasket. The summed displacement is used as the desired displacement for the second stage.
