Title: Method for improving noise ratio in optical wave transmission system
Inventor: TOOMASU EDOWAADO DAASHII
IPC: H04B10/07
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To improve the relative efficiency by increasing the C/N (the ratio of carrier to noise ratio) without deteriorating signal quality due to increasing nonlinear distortion so as to allow much more users to receive service by the optical wave system per one laser in the optical wave transmission system where a laser light source is modulated by an RF carrier signal and an output of the laser light source is coupled optically with a receiver decoding a modulation signal. SOLUTION: A bias preliminary adjustment circuit 120 is constituted of an envelope generating means 130 for generating an envelope of an RF carrier signal and an adjustment means changing a bias current with respect to a laser light source 180 in response to the envelope. An output average optical current is reduced comparison with a conventional method so as to reduce a nonlinear distortion level by changing the bias current so as to allow the bias current with respect to the modulated laser light source 180 to trace the envelope of the RF carrier signal.

IPC: H04N1/113
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To form an image with high image quality by converting digital image data into plural analog image signals, comparing any of the analog image signals with any of reference pattern signals, and forming a pulse width modulation signal on the basis of the result of comparison so as to form plural pulse width modulation signals while suppressing the cost and consumed energy.

Title: Cartridge with openable/closable recognition hole and its method and device for driving
Inventor: KO JUNG-WAN
IPC: G11B23/03
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To recognize the state of a disk for recording without another verification after replacing a disk by arbitrarily opening and closing a recognition hole according to the opening state of a cartridge and the inspection state of the disk. SOLUTION: A sensor lever 50 has a tension part 54 being brought into contact with an opening and closing display member 52 of A1 recognition holes 24 and 34 and the side surface of upper and lower shells 20 and 30. The tension part 54 is brought into contact with the side surface of the upper and lower shells 20 and 30, and at the same time applies fixed tension to the sensor lever 50. When an opening cover 40 is not fitted or is in an open state, the opening and closing display member 52 is set to the opening position of the A1 recognition holes 24 and 34. Furthermore, a nib with elasticity is created at a middle part of the A1 recognition hole 24.  When the opening and closing display member 52 of the sensor lever 50 is set to a closing position, the elasticity of the tension part 54 of the sensor lever 50 is used to support the opening and closing display member 52 for preventing the opening and closing display member 52 from returning, thus arbitrarily opening and closing the A1 recognition hole 24.

Title: Method and device for measuring gas leak of container
Inventor: KO SEIYO
IPC: G01M3/26
Filed: 1992-12-25
Abstract: PURPOSE:To accurately measure the air leakage of different containers to be measured by using the same reference container by measuring a differential pressure between the respective containers at a point of later when the compressed gases in respective containers attains a thermal equilibium state after the container to be measured and the reference container are filled with a compressed gas. CONSTITUTION:After a solenoid valve SV1 is turned on, the valves SV2 and SV3 are simultaneously turned on to supply a compressed air to a reference container MV and a container to be measured WV from a compressed air source S. The pressures in the containers MV and WV raise and at a point when the both reach a supply pressure PS, the filling is completed and the differential pressure becomes zero. Then, when the supply of compressed air is stopped at a point of time tb, the pressure Pm in the container MV gradually drops due to the temperature change of the compressed air, and the pressure Pw of the container WV due to the temperature change of the compressed air and leakage, respectively, thereby generating a differential pressure D. After the differential pressure D shows its peak at a point of time tc, it attains thermal equilibium state at a point of time ts. A differential meter DPS measures the differential pressure D (t) with time elapse caused by only leakage at the point ts or later and calculates a leake ratio q.

Title: Measuring apparatus of thickness of swelling film
Inventor: TADOKORO EIICHI
IPC: G01B11/06
Filed: 1991-12-09
Abstract: PURPOSE:To correctly measure the thickness of a swelling film by providing a light permeable diaphragm between light emitting and light detecting elements and a sample, a liquid feeding means and a control means for measuring the thickness of the film after the liquid is filled between the sample and the diaphragm. CONSTITUTION:A supporting stage 4 is hollow. Many holes 24 are opened on the supporting surface 4a which supports a sample. A liquid storing member 10 is a hollow cylinder, and connected with a liquid feeding pipe 26 and a discharge pipe 28 so that a liquid to swell a sample 6 is filled in or discharged from the member 10. While the sample 6 is held by the supporting stage 4 and the member 10 in the liquid-tight state, a liquid 8 is supplied into the member 10 from the liquid feeding pipe 26. As a result, the liquid level is raised to be in touch with a surface 20a of a covering face 20 of a photosensor 12. The liquid level is detected by a liquid level sensor 30 provided in the discharge pipe 28 and a signal is output to a control device 22. When the signal is fed to the device 22 from the sensor 30, the device 22 activates a light emitting element 16 and a light detecting element 18 thereby to measure the film thickness. Since the cover 20 becomes an interface to the liquid 8 and is not varied, the thickness of the swelling film of the sample 6 can be correctly measured.
