摘要:
A prolonged releasing pharmaceutical preparation is provided carrying a physiologically active substance, particularly, calcitonin gene-related peptide (CGRP) or a maxadilan (MAX). This pharmaceutical preparation can attain the expected effects by incorporating the physiologically active substance into a combination, as carriers for the physiologically active substance, of a cellulosic polymer and at least one auxiliary component selected from the group consisting of fats and oils, waxes, fatty acids, saccharides and polyacrylate ester derivatives. The pharmaceutical preparation can conveniently be used, in living bodies, particularly as an intrathecal implantation-type preparation.

An ECU includes a microcomputer that has an integrated flash memory. An initial writing flag is set in the microcomputer before an initial writing to the flash memory. The microcomputer enters into a writing mode when the flag determines permission of data writing. When the data-writing to the flash memory is completed, the flag is cleared.

A digital color camera for converting an input optical image to a standard color television signal by using digital signal processing techniques includes: an image sensor for converting optical signals to a series of pixel signals; an analog to digital converting circuit for producing digital pixel signals; a digital signal detecting circuit for separating the digital pixel signals into a digital luminance signal and a digital chrominance difference signal; a digital chrominance signal processing circuit for producing two independent digital chrominance difference signals; a digital luminance signal correction circuit for making a gamma correction on the digital luminance signal; a color television signal encoding circuit for producing an analog standard color television signal from the two independent digital chrominance difference signals and the gamma corrected luminance signal. These circuits are controlled by timing pulses produced by a control timing generating circuit driven by a driving circuit. The digital signal detecting circuit includes: a pixel signal separation circuit for separating the digital pixel signals into two digital color pixel signals; a first digital addition circuit for adding the two digital color pixel signals; a pixel signal inverting circuit for inverting one of the two digital color pixel signals, and a second digital addition circuit for adding the other of the two digital color pixel signals with an output signal of the pixel signal inverting circuit.
摘要:
A color television receiver receiving two television signals of different channels, compressing the time axis of one of the television signals, and inserting this compressed television signal in a portion of the other television signal for displaying the pictures of the two channels on the same screen. In the receiver, the luminance signal, chrominance signal and synchronizing signal are derived from each of the received two television signals. A writing clock pulse signal is produced on the basis of one of the synchronizing signals for writing the luminance signal and chrominance signal in the corresponding television signal in a memory circuit, while a reading clock pulse signal is produced on the basis of the other synchronizing signal to read out the luminance signal and chrominance signal from the memory circuit in a relation in which these signals are compressed in the time axis. After the luminance signal and chrominance signal read out from the memory circuit are adjusted in their signal levels relative to the luminance signal and chrominance signal in the other television signal, a portion of the luminance signal and chrominance signal in the other television signal is replaced by the luminance signal and chrominance signal read out from the memory circuit so that the pictures of the two channels can be displayed on the same screen.
