A debugging aid apparatus that provides fetching system call data which includes a return address to the application task, but not, a return address to a high-level language interface routine, as the return address on completion of the system call instruction, when the system call is issued to an OS through the high-level language interface routine from an application task written in a high-level language.

Debugging aid apparatus

A digital control device includes a first controller which generates a control reference signal of a first controlled variable of a controlled system, a first frequency converter which converts said control reference signal into pulses of a frequency proportional to a magnitude thereof, a second frequency converter which converts a measured value of a second controlled variable of said controlled system into pulses of a frequency proportional to a magnitude thereof, and a second controller which obtains a difference between the output pulses of said first frequency converter and the output pulses of said second frequency converter and which controls said second controlled variable by using said difference as a control reference value.

Digital control device

Novel nitrogen-containing monoterpene derivatives having pyrindine skeleton and dimers, trimers and higher polymers thereof as low toxic and efficient dyestuffs. Their pharmacological effects are expected.

PCT No. PCT/JP78/00054 PCT Filed Dec. 14, 1978 Sec. 371 Date Aug. 9, 1979 Sec. 102(e) Date Aug. 9, 1979 PCT Pub. No. WO79/00394 PCT Pub. Date Jul. 12, 1979. Novel reddish coloring compounds of varying hue and the method for its production, obtained by reaction between iridoid compounds contained in biological substances, where if necessary, by pretreatment with chemical or enzymic means to form --COOH at the C-4 position, and in the case of glycosides by hydrolysis of iridoid compounds to aglycones with chemical or microbial or enzymic means, and a substance possessing a primary amino group under acidic condition.

Red coloring composite and the method for its production

Novel nitrogen-containing monoterpene derivatives having pyrindine skeleton synthesized by, for example, substitution of an oxygen atom in an iridoid skeleton for a nitrogen atom as low toxic and efficient dyestuffs. Their pharmacological effects are expected.

Nitrogen-containing monoterpene derivatives

Neoschizophyllan is produced by an ultrasonication of Schizophyllan which is extracted from a culture solution of Schizophyllum commune Fries or a fruit body thereof.
