IPC: H03G3/00
Filed: 1982-06-24
Abstract: PURPOSE:To allow an amplifier, when powered on, to start in a fade-in state without fail by resetting a D type flip-flop which drives an electronic attenuator inserted in the input side of an amplifying circuit for amplifying a signal a little bit after the amplifier is powered on. CONSTITUTION:When the power supply switch of the amplifier is turned on, the flip-flop 1 enters in an operation state immediately and a clock pulse is applied to a terminal C2 of a flip-flop 3 by operating a fader switch SW. Then, a terminal Q2 of the flip-flop 3 is held at a level H and the potential of a point A of an integrating circuit 10 rises gradually. When the potential at the point A reaches a saturation point and a transistor TR turns on, a terminal R2 of the flip-flop 3 has H-to-L level transition and then a protection relay 8 conducts to increase the signal transferability of the electronic attenuator 11 through the operation of a relay operation detecting circuit 6. At the same time, a relay switch S is turned on by the protection relay 8, so a signal applied to a signal input terminal 13 is amplified by the amplifying circuit 14 and transferred to a signal output terminal 15, and its value increases gradually.

Filed: 1978-09-07
Abstract: PURPOSE: To keep pickles from air, and preserve the fresh taste of the pickels, by the use of a pickle tub having a cylindrical weight fitted in the tub and consisting of a hollow vessel containing predetermined weight of stones, sand, etc. and furnished with a pipe to connect the pickles to outer atmosphere.  
     CONSTITUTION: Green vegetables 2 seasoned with 3W5wt% of salt are put into a cylindrical pickling tub 1. The weight of the green vegetables is equal to the volume determined by subtracting the volume of the automatically balancing weight 4 from the total volume of the pickle tub 1, and reducing 1cc to 1 gram. The weight 4 consisting of a hollow vessel is filled with saline water having same concentration as the vegetables to be pickled, or weighted with sand having same weight as the saline water. According as the impregnation of the added salt into the vegetables, the water existing in the vegetables is exuded and air is expelled upward and discharged through the air-pipe 5 at the center of the weight 4. When air is completely discharged, the water level in the tub becomes nearly equal to that in the weight 4, and the weight 4 loses the role of weight and acts only as an air-tight cover.

Title: Recording and reproducing system for digital data contained in video format signal
Inventor: MORIYAMA YOSHIAKI
IPC: H04N5/92
Filed: 1983-06-18
Abstract: PURPOSE:To detect a part which is replaced by compensation for drop-out as an error and to correct this error by adding an error detection bit which is inverted every prescribed period to a partial digital data of a video format signal. CONSTITUTION:For the reproduction signal of three blocks, etc. produced every horizontal period H, a part of a video format signal of a data word D having (m) words for each block B is formed with the digital data of a cyclic code CRC and an error detection bit (b), etc. of one bit, etc. which is inverted every period H. Then a part of the reproduction data on the 2nd period H owing to a drop-out. Thus the detection of errors is impossible for a data word D1.2 of a block B2.2 having blocks all replaced with a code CRCC1.2. Then a bit b1.2 of the block B2.2 is compared with a bit b1.2 of a block B1.2 which is ahead by three blocks. If the coincidence is obtained from this comparison, a flag is inverted and a parity correcting circuit is activated. Thus the word D1.2 undergoes the error correction if an error is detected through a parity check.

Title: Oxygen sensor output circuit
Inventor: SHIMOMURA SETSUHIRO
IPC: G01N27/04
Filed: 1980-08-09
Abstract: PURPOSE:To obtain a detection output free from voltage drop of an internal resistance in an oxygen sensor varying with the temperature of exhaust gas by selectively connecting a capacitor to an oxygen sensor and an amplifier with a given repetition cycle. CONSTITUTION:Synchronizing a specified frequency output of an oscillator 8, a changeover switch 7 alternately connects a capacitor 6 to input terminals of an oxygen sensor 1 and an amplifier 2. When the capacitor 6 is connected to the oxygen sensor 1, it is charged to attain the electromotive foce of the oxygen sensor 1 itself eliminating voltage drop due to an internal resistance r of 1. When the capacitor 6 thus charged is connected to the input terminal of the amplifier 2, the minimum value of the output voltage V01 from the amplifier 2 is stable free from the internal resistance r of the oxygen sensor 1 both at the high temperature and the low temperature of the exhaust gas. Setting the reference voltage Vref slightly higher than this constant minimum value enables a comparator 5 to generate an output corresponding to the theoretical air/fuel ratio.
