Title: Safety disc brake for lifts
Inventor: VERTESY JOSEF
IPC: B66D5/14
Filed: 1991-06-18
Granted: 2003-05-06
Abstract: With this safety disc brake, all requirements due to regulations can be fulfilled with a constructional effort which is about equal to that for a simple construction. The fulfilment of the most important safety requirement is achieved thereby, that two partial systems, which each operate mechanically completely independent of the other, are provided in the form of two identical brake levers (4) each with a respective separate compression spring (7, 8), which are supported at a common spring abutment centre (2.3) and which is in its turn connected fast with a machine part (1). As further feature for the fulfilment of the safety requirements, both the partial systems display no mutual mechanical interpenetrations and overlappings. The clearing function of the brake takes place electromagnetically by means of a pot magnet (5), which is rigidly fastened at one brake lever (4) and an armature plate (6), which is likewise rigidly fastened at the other brake lever (4). The fastenings of the pot magnet (5) and the armature plate (6) at the brake levers (4) are adjustable in order that the armature plate (6) is always attracted exactly parallelly by the pot magnet (5) and thus no impact noise is generated.

Title: Gradation corrector
Inventor: TSUJI TOSHIAKI
IPC: G06T5/40
Filed: 1992-05-25
Granted: 1999-04-20
Abstract: A gradation corrector for use in a television receiver which can subject a signal at any luminance level to non-linear correction to provide optimum image quality.  Memory stores therein luminance histogram of an input signal.  On the basis of the data, a circuit detects a total frequency, a circuit detects luminance distribution, and a circuit detects the expanse of the luminance distribution.  A circuit calculates a fixed value to be added.  Further, a circuit detects a  minimum luminance level, and a circuit detects an average luminance level.  A circuit calculates an accumulation starting point and a circuit calculates an accumulation stopping point.  An adder adds the calculated fixed value to the data in the memory.  A circuit accumulates the results in the range from the accumulation starting point to the accumulation stopping point.  The accumulation result is stored in memory.  A circuit detects the maximum cumulative value, and a circuit normalizes all the data stored in the memory by use of this maximum value.   The normalized data are stored in a memory.  Thus, the input signal is subjected to optimum normalization by use of the normalized data.
