Title: New promoter
Inventor: KOBAYASHI OSAMU
IPC: C07H21/04
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain a new promoter originated from a specific beer yeast, having a specific DNA sequence or its homologous sequence retaining the activity, exhibiting a high promoter activity and capable of being utilized in a different kind gene-expressing system using a yeast as a host. SOLUTION: This promoter comprises a DNA fragment having a DNA sequence of the formula having a promoter activity or a sequence homologous to the DNA sequence and retaining the promoter activity. The DNA fragment has a high promoter activity, can be utilized in a different kind gene-expressing system using a yeast as a host, and is useful for producing proteins such as α-acetolactic acid decarboxylase, alcohol acetyltransferase and glucoamylase. The DNA sequence is obtained by cloning a bottom beer yeast (Saccharomyces cerevisiae Lg-FLO 1) gene from the chromosome of the bottom beer yeast, and subsequently collecting the DNA fragment containing the highly active promoter from the cloned product. The DNA fragment containing the highly active promoter is found out by examining the gene-expressing property of the cloned product.

Filed: 1988-02-23
Abstract: PURPOSE:To attain adjustment of contrast by providing a switch circuit operated in the timing synchronized with a synchronizing signal of a video signal and a peak detection circuit for a video signal. CONSTITUTION:In case of arrival to an equilibrium state, a capacitor 3 is charged from a reference power supply 2 for a period 19-1 and the capacitor 3 is discharged to the reference power supply 2 for a period 20-1, and no charge/ discharge is applied for the period of synchronization because switches 5-1, 5-2 are reset. In the equilibrium state, the area of the hatched part of the waveform 19-1 and the area hatched in the waveform 20-1 are equal, and the similar relation exists between the waveforms 19-2, 20-2. Thus, the DC voltage 21 of the black level of the video signal at the base of a transistor Q7 is lowered with a large APL(average peak picture level) when the APL is larger. Thus, the contrast adjustment is attained.

Since the heat on the outside of the protective pipe 1 is rapidly transmitted to the hot junction 7 and, therefore, the responsiveness is improved. Since other metals are not incorporated in the hot junction 7, the accuracy of the measurement is good. The enhanced durability is obtd. as the hot junction 7 does not come into direct contact with the outdoor air.
