Patent JP-H08297922-A (JP)
Title: Method and device for recording and reproducing digital signal
Inventor: OWASHI HITOAKI
IPC: H04N19/89
Filed: 1995-04-27
Abstract: PURPOSE: To inhibit the duplication of recorded information by efficiently recording packeted digital information in a recording and reproducing device at close packet intervals by adding arriving time information to each packet and, at the same time, changing at least one bit of the time information added to the information at the time of reproducing the information. CONSTITUTION: Packeted(PK) digital information is efficiently recorded in a recording and reproducing device by making the PK interval shorter by adding a time stamp(TS) indicating the arrival time of PK to each PK. Then reproduced signals are sent to a memory 520 and TS reading circuit 550 at every PK through a memory 510. When a coincidence detecting circuit 552 detects the coincidence between the outputs of the TS reading circuit 550 and a count circuit 551, a TS gate circuit 530 outputs the signal in the memory 520 by returning the PK interval to the original time interval and changing at least one bit of the TS information. Therefore, the duplication of the information recorded in the recording and reproducing device is inhibited.

Filed: 1978-08-26
Abstract: PURPOSE:To improve the safety against oxygen starvation through partial absorption and oxidation of the high velocity combustion gas by passing thereof through a heated catalyst before a feed gas with a high combustion speed is injected from a flame port. CONSTITUTION:A ceramic body impregnated with platimum or a ring-shaped ceramic body is securely inserted into a pilot pipe 1 made of brass or other metal at a position close to the tip flame port 2. After injected from a nozzle 4, the feed gas is sucked from the primary air port 5, pass through the ceramic body 3 mixed with the primary air and then, injected from the port 2. Since the ceramic body is left at a low temperature, immediately after the ignition, the gas passes as intact and burned at the port 2. In time, the combustion heat is transmitted to the ceramic body through the pilot pipe 1. When it is heated up to 100 deg.C or so, the passing gas is oxidized by the catalyst and reformed to a gas low in the combustion speed so that it can be burned normally.

Abstract: PURPOSE:To reproduce Hi-Fi sound without generating a pack noise by providing a slice circuit before a detection circuit in reproduction. CONSTITUTION:In the reproduction, a frequency demodulated audio signal is inputted to an amplifier circuit 2 via an audio signal input terminal 1. At this time, the circuit 2 goes to a buffer circuit since a recording/reproduction change- over switch 3 is connected to a reproduction side. Also, the output of the circuit 2 is inputted to a recording/reproduction change-over switch 11 and an NR (noise reduction) emphasis circuit 8, and since the switch 11 is connected to the reproduction side, a signal is inputted to the slice circuit 10. At the circuit 10, the level of a signal component with a low level is further lowered, and is inputted to a waiting circuit 6. At the circuit 6, characteristic of high-pass ascent with a prescribed time constant is attached, and peak-detection is applied on the signal at the detection circuit 7. Meanwhile, after characteristic of high- pass descent with a prescribed time constant is attached on the signal at the NR(noise reduction) circuit 8, it is extended by the detecting level of the circuit 7 at a VCA circuit 9. An extended signal is outputted via a reproducing output terminal 5.

Abstract: PROBLEM TO BE SOLVED: To more reliably kill microorganisms existing on or near the surface of a separation membrane by carrying out a water acidifying step in which the pH of water supplied to a membrane separation apparatus is adjusted to a specified value or less while separating and purifying water using the membrane separation apparatus compared with a conventional method in which high concentration sodium hydrogensulfite is added intermittently. SOLUTION: In a membrane separation apparatus, e.g. a reverse osmosis membrane apparatus, a liquid to be treated is supplied to a membrane module under pressure and separated into permeated and concentrated liquids so as to carry out the production of fresh water, concentration or separation. The membrane can reliably be sterilized by setting the pH at <=4 and the sterilization is effectively applied to membrane filtration using seawater as water to be supplied. An acid is ordinarily used for pH adjustment and sulfuric acid is preferably used because it is economical. In order to attain <=ph 4, >=120 ppm sulfuric acid is preferably added. Sulfuric acid is preferably added for 0.5-2.5 hr at intervals of 1 day, 1 week o 1 month.

Title: Lateral feeder in printing mechanism
Inventor: FUJIWARA SHINSUKE
IPC: B41J19/20
Filed: 1987-04-28
Abstract: PURPOSE:To enable a required speed reduction ratio to be sufficiently obtained even in a small space, by constructing a speed-reducing system by causing a feed screw shaft for feeding a printing head part and a driving motor shaft to be coaxial with each other. CONSTITUTION:A third gear 23 is differentially moved by a planetary gear action of a first gear 21, which revolves round a second gear 22 under a rotational driving force of a driving motor 17 while rotating on its own axis, and the third gear 23 is rotated in a predetermined speed reduction ratio in a direction opposite to the rotating direction of the first gear 21. The speed reduction ratio of the third gear 23 relative to the motor 17 is uniquely determined as represented by the formula (N1-N2)/N1, where N1 is the number of teeth of the third gear 23 and N2 is the number of teeth of the second gear 22, irrespective of the number of teeth of the first gear 21. When the number of teeth N1 of the third gear 23 is set to be greater than that N2 of the second gear 22 (N1>N2), a feed screw shaft 12 is rotated in the same direction as the rotating direction of the motor 17. When a speed-reducing system is thus composed of a planetary gear mechanism to constitute a power transmission mechanism, a driving shaft 18 of the motor 17 and the feed screw shaft 12 can be coaxially disposed on the center axis.
