Title: Pcm recording and reproducing device
Inventor: OZAKI MINORU
IPC: G11B5/09
Filed: 1979-09-17
Abstract: PURPOSE: To detect an editing point by error distribution characteristics of a signal, recorded on the multitrack of a recorded PCM magnetic tape, at the editing point of the magnetic tape, by delaying a track where a PCM signal has been distributed.  
     CONSTITUTION: An analog input signal to terminal 1 is modulated by an A/D converter into a PCM signal, which is distributed to respective tracks by code adding circuit 3 and also given an additional error detecting code. Signals to some of tracks are delayed by a constant number of frames at delay circuit 4 and recorded via modulating circuit 5. A reproduced signal is PCM-demodulated by demodulating circuit 9 and supplied to error detecting circuit 10 for a PCM signal to detect its error. The error detection output result is led to editing processing circuit 13 by way of editing detecting circuit 12. The reproduced PCM signal is converted in time series into one by the parallel-series converting circuit, whose output is edited by editing processing circuit 13 before being outputted via A/D converter 14.

Title: System and method for safe and scalable data base transaction by network
Inventor: SILVERMAN VLADIMIR
IPC: G06F3/048
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To improve security, functions, performances, and flexibility by separating transaction software from a data base itself and authenticating a user. SOLUTION: A client 301b and a transaction server 302 are connected to a network 303. The transaction server 302 is connected to a data base server 304, which is connected to the data base 305. The transaction server 302 identifies and authenticate a requesting user. Once the user is authenticated, the transaction server 302 retrieves an instruction statement and substitutes a user data base request for parameters of the instruction statement to evaluate the instruction statement. Then an executable instruction statement is sent to the data base server 304. The data base server 304 executes the instructions statement and sends its execution result to the transaction server 302. Results like this are sent from the transaction server 302 to the client.

Title: Tape reel
Inventor: KAWAMICHI KATSUHIRO
IPC: G11B15/66
Filed: 1977-10-04
Abstract: PURPOSE: To prevent uneven take-up of tape by providing air inluent holesfto flanges and loosely fitting a pair of disc form thin plates to a reel hub.  
     CONSTITUTION: When a reel turns at the tape take-up, the air influent through a plurality of holes 3...provided to the root part of flanges 1, 1 directs toward the radial direction by the effect of centrifugal forces. This causes the easy-to-delecft disc-form thin plates 4, 4 loosely fitted to a hub 2 to deflect inward. Hence, the tape 5 being taken up on the hub 2 is held between the thin plates 4, 4 and is thereby evenly taken up under edge-sligned condition, whereby damaging of the tape occuring owing to uneven winding, etc. may be prevented

Abstract: PROBLEM TO BE SOLVED: To uniformarize magnetic field intensity distribution, to increase the arc contact area, and to improve the cutoff performance by connecting the base end of the arm part of each coil electrode to the side circumference of the base part opposite to the extending direction of a coil part to the center of the base part. SOLUTION: In coil electrodes 12, 22, the extending direction of a circular part 12c (22c) and the connecting position of the base end of an arm part 12b (22b) to a base part 12a (22a) are set so as to be opposite to each other to the center of the base part 12a (22as). In the state where the coil electrode 12 of fixed electrode and the coil electrode 22 of movable electrode are mutually laminated, the clearance area A formed between each arm part 12b of the coil electrode 12 and each arm part 22b of the coil electrode 22 is significantly contracted. Thus, the clearance area A with weak magnetic field intensity can be minimized, and the magnetic field intensity distribution can be uniformarized by that to effectively extend the arc, so that the arc can be diffused over a wide area of a contact member.

Abstract: PURPOSE:To prevent the adhesion of drain to the inner wall of a casing and make it hard to generate boiling in a pipe, by a method wherein a first heat transfer tube, laid along the flow direction of combustion gas, a second heat transfer tube, having fins higher than fins for the first heat transfer tube, and a third heat transfer tube, contacting the wall of a casing, are arranged in the casing for passage of water in the sequence of the first, second and third heat transfer tubes. CONSTITUTION:A first heat transfer tube 15, nearest to a burner plate 12, receives the strongest heat flux from combustion gas, however, water of initial period is flowed through the first heat transfer tube 15, therefore, boiling in a pipe may be prevented. A combustion gas temperature and water temperature in the pipe is high in the second heat transfer tube 16, therefore, the temperature of fins 26 of the heat transfer tube is kept higher than a dew point and the generation of drain may be restrained remarkably. Further, the temperature of water passing through the third heat transfer tube 17 has risen sufficiently, therefore, the adhesion of the drain may be restrained and prevented remarkably. Accordingly, the corrosion of the casing 11 due to the drain or the damage of a combustion means due to the adhesion of the drain will never be generated.
