Abstract: An electronic control unit has a microcomputer and a signal monitoring circuit. When a brake pedal is pressed down and an analog signal from a brake pedal sensor is changed in a low power consumption operation mode of the microcomputer, the signal monitoring circuit operates cyclically. When the signal monitoring circuit starts the operation, a capacitor is charged with a constant current for only a charging time stored in a memory. When a comparator detects that the analog signal is lower than the charge voltage of the capacitor, a wakeup signal is output from the comparator to the microcomputer to cause the microcomputer to operate in the normal operation mode. The charging time is pre-stored in a memory of the microcomputer.

Abstract: When it is determined that a driver is extremely-concentrating, a fragrance emitted by a relaxing air freshener is intermittently released by emitting. To quickly reduce the tension of the driver, a long fragrance emit period is set, while a short fragrance emit stopped period is set. When it is determined that the driver is randomly scanning, the amount of the relaxing air freshener discharged is smaller than that when the driver is extremely-concentrating, and a shorter fragrance emit period is set, while a longer fragrance emit stopped period is set. As a result, an aroma that is so faint that the driver may not notice is used to maintain the random scanning state, and further, a fragrance emitted by an awakening air freshener is emitted, as needed, near the nose of the driver.

Abstract: An electron emitting source 6 is covered with a cathode mask 20 whose opening areas are substantially the same as those in a grid electrode 10, so that the areas for which the electrons are emitted from the electron emitting source 6 can substantially be the same as the opening areas in the grid electrode 10. Thus, substantially all the electrons emitted from these areas can be ensured to pass through opening portions 11 in the grid electrode 10 so as to be effective electrons that can contribute to light emission. In this way, power loss at the grid electrode 10 can be reduced. At the same time, harmful metallic sputtering caused at the grid electrode 10 toward a cathode electrode 5 can be reliably prevented, whereby damages on the cathode electrode can be avoided.

Abstract: Echinatin glycosides are disclosed having the following formula ##STR1## wherein R.sub.5 and/or R.sub.6 is a glycosyl residue. These substances have pharmacological effects such as the inhibiting action of the echinatin-4'-glucoside on the growth of human lymphoblastoids. These compounds may be chemically synthesized by subjecting a compound of the following formula ##STR2## to reaction with a compound represented by the following formula ##STR3## in which R.sub.1 and/or R.sub.2 is a glycosyl residue or an acyl glycosyl residue, with the optional successive step of subjecting the resultant to reaction with a glycosyl halide or an acyl glycosyl halide.

Abstract: A process for the biosynthesis of echinatin-4-glucoside comprises cultivating calli of Glycyrrhiza echinata L. (Leguminosae) in an appropriate nutrient medium. The echinatin-4-glucoside appears in both the calli and the culture broth and may be extracted and separated therefrom.
