Title: Method of culturing hydrogen-assimilating bacteria
Inventor: MIURA YOSHIATSU
IPC: C12N1/20
Filed: 1978-11-15
Abstract: PURPOSE: A hydrogen-assimilating bacterium, especially a mold belonging to Alcaligenes, is acclimatized to permit the continuous cultivation with higher specific propagation rate than the maximum one in batchwise cultivation.  
     CONSTITUTION: A hydrogen-assimilating bacterium belonging to Alcaligenes, especially Alcaligenes hydrogenophilus (FERM-4715), is continuously cultured by starting from low dilution rate, then gradually increasing the ratio in a culture medium containing inorganic nutrients and having a pH of 6.5W7.5 at a temperature 30W35°C with passing a mixture of hydrogen, oxygen and carbon dioxide. The bacterium is acclimatized in this manner until the specific propagation rate steadily reaches the same or exceeding level as the maximum ratio in the batchwise cultivation and the resulting mold is cultured continuously under conditions where it shows the same as or higher level than the maximum propagation ratio.

Title: Control signal detection system
Inventor: YAMAZAKI SHIGERU
IPC: G11B15/087
Filed: 1978-11-17
Abstract: PURPOSE: To detect definitely an automatic stop control signal, etc., existing by detecting the existence of a control signal formed of signals mutually differing in frequency, by counting changes in frequency of the control signal to a fixed number.  
     CONSTITUTION: Detector 5 equipped with band-erasing circuit 11, rectifying integral waveform forming circuit 12, inverter 13, BFP15, rectifying integrating circuit 16, AND gate 14, etc., generates a detection pulse of width equivalent to the existence period of signal (f 1 ) of the control signal formed of mutually-different frequencies (f 1 ) and (f 2 ) without being influence by noises. In response to this pulse, the monostable multivibator of input-change detection circuit 7 generates a pulse of a little bit wider width to open AND gate H. On the othe hand, a pulse outputted at the time of a change between signals (f 1 ) and (f 2 ) outputted by gate 24 applied with a detection pulse of signal (f 2 ) from similar detection circuit 6 is counted by counter 8. When this count value reaches a fixed value, an existence detection signal of the control signal is generated through monostable multivibrator 9.

Title: Controller for vacuum cleaner
Inventor: IMAI HIDETOSHI
IPC: H02P27/02
Filed: 1987-06-05
Abstract: PURPOSE:To remove wasteful power loss, and to obtain a vacuum cleaner having excellent efficiency by completely eliminating the cutting of the phase of voltage when the full power of the vacuum cleaner is used. CONSTITUTION:A zero volt pulse generating section 9 is connected to a commercial power supply 1, and generates zero-volt pulses synchronizing with the zero- cross point of the commercial power supply 1. When output voltage from a comparison voltage generating section 6 reaches a certain voltage or less, a pulse changeover section 10 conducts operation in which an output from the section 6 is changed over to zero volt pulses. Accordingly, since a bidirectional thyristor 3 is zero-cross triggered when full power is used, the cutting of the phase of voltage is eliminated, and wasteful power loss is removed, thus acquiring a vacuum cleaner having excellent efficiency.
