Title: Device for preventing corrosion due to cavitation
Inventor: OOMAE ATSUSHI
IPC: F04D29/66
Filed: 1982-04-14
Abstract: PURPOSE:To prevent the generation of corrosion due to cavitation by a method wherein a small hole is bored on a suction pipe at a suction level of an effective suction head within the actual operating range of a pump and below the necessary suction head and air is sucked from the small hole when the level of the water is made lower than said suction level. CONSTITUTION:The small hole 4 is bored at the neighborhood of the suction level (below H1) of the effective suction head within the actual operating range of the pump and below the necessary suction head. When the suction level in an intake tank 1 is lowered and the effective suction head arrives at a position H2 below the necessary suction head, the small hole 4 is exposed automatically and air is sucked from the small hole 4, thereby preventing the generation of the corrosion due to the cavitation by a damper effect which is one of the properties of the air. When the suction level is elevated, the effective suction head has become higher than the necessary suction head and it arrives at a position higher than the position H1, in which the generation of the cavitation is out of the question, the small hole 4 is hidden below the water level and pouring of air is stopped automatically.

Title: Method and system for ciphering and decoding encoded musical sound
Inventor: NISHIHARA YUICHI
IPC: G10L19/06
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To confirm a part of the features of original musical sound even in the case of performing reproduction without decoding ciphers by leaving a part of the feature value and residual value of original musical sound signals without ciphering it or adjusting the degree of difference generated between an original signal value by ciphering. SOLUTION: An encoder 300 extracts the feature value of the musical sound signals in multiple stages in a feature value extraction means 310, divides them into the extracted feature values of the respective stages and the residual value of the original signals and the extracted feature values in a separation means 320 and encodes the separated musical sound signals in an encoding means 330. Then, a ciphering means 100 performs ciphering to the feature values of the respective stages of the encoded musical sound signals. A decoding means 200 decodes the feature values of the respective stages of the ciphered musical sound signals. Thus, the contents of the original musical sound signals are confirmed from the feature values left without being ciphered even in the case of reproducing the ciphered signals.

Filed: 1993-02-26
Abstract: PURPOSE: To provide a gas flow control system for feeding a sample gas to an ion-trap mass spectrometer, with an ability to make the sample gas flow and stop it, without generating pressure surge in an ion trap. CONSTITUTION: A sample gas flow control system is used, along with an ion-trap mass spectrometer. The sample gas flows through a first gas flow restrictor 70 from a gas source 5. The first gas flow restrictor 70 is connected to second and third gas flow restrictors 80, 90. The second restrictor 80 is connected to an ion trap 10, where the sample gas is used, and output of the third restrictor 90 is connected to a vacuum pump which may be a roughing vacuum pump 20 used by the ion trap. At least one of three restrictors is a variable restrictor. A simple, inexpensive element can therefore be used for accurate flow control.

Title: Coupling device
Inventor: MOTEGI MITSUHIRO
IPC: H04B10/00
Filed: 1980-05-09
Abstract: PURPOSE:To maximize the coupling quantity between the light emitting element and the optical fiber, by vibrating the fiber to detect the light output for this vibration. CONSTITUTION:The light from light emitting element LD is incident to optical fiber F, and a part of this light is monitored by photodiode PD. Optical fiber F is vibrated through oscillator OSC, amplifier AMP1, and piezo element P. The output of PD is applied to phase detector PHD through band-pass filter BPF and limiter amplifier LAMP, and the output of OSC is applied to this phase detector PHD also through phase equipment PH. If optical fiber F is slipped off from the center position of the junction of light emitting element LD, the output of PD and the output of LAMP have phases shifted from each other, and therefore, the output corresponding to the phase difference is generated from phase detector PHD and is applied to piezo element P as a bias voltage. Optical fiber F is displaced in accordance with this bias voltage and is vibrated with the position due to displacement as the center.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To provide a means capable of stably conveying articles difficult to handle, such as a bag, a small article or the like, in each lot unit, and reducing a space for conveying equipment. SOLUTION: In the case that articles carried in a conveying line 10 including first-forth belt conveyers 14-20 connected in series are fed in another line 12 in each lot unit, the respective conveyers 14-18 are controlled such that constant intervals between the articles are formed when the articles are transferred from the first conveyer 14 to the second conveyer 16, and that the articles are transferred to the third conveyer 18 with the intervals kept to form one lot. The articles on the third conveyer 18 corresponding to one lot are transferred to the forth conveyer 20 driven independently of the first-third conveyers 14-18, and are timely fed in the conveying line 12. This method assuming use of the belt conveyers 14-20 can achieve stable conveyance of the articles and reduction of a space.

Abstract: PURPOSE:To enhance the reliability in reading of the rugged preformat provided on a substrate and to decrease the fluctuation in the reflectivity in a card down to a low level by forming the signal pits of the preformat to the depth smaller than the depth of track grooves. CONSTITUTION:A recording medium 2 formed by coating of a recording material such as dye is provided on the substrate 1 formed with the signal pits 5 of the rugged preformat to the depth smaller the depth of the track grooves 6. The recording medium 2 and a back material 4 for protection or for supporting the recording carrier are adhered via an adhesive layer 3.

Abstract: PURPOSE:To connect an antenna which is in best condition at all times to a receiver, by detecting the intensity of received electromagnetic waves for all the antennas periodically, selecting the antenna having maximum value of the intensity of received electromagnetic waves, and switching the receiver to this antenna. CONSTITUTION:Assuming that an antenna switching circuit 7 selects a reception antenna A1 and it is connected to a FM radio receiver 9.

The detection and storage is repeated at a given period. When the reception signal of the antenna A1 which is detected at a reception state detecting circuit 11 is lower than the maximum storing value of the circuit 13, a switching control circuit 14 controls the circuit 7 and switching is made so that the receiver 9 can be connected to an antenna with the maximum reception level stored by the circuit 13.

IPC: G06F3/0488
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To display an input picture suited for an input user by discriminating the skill of input user's input operation. SOLUTION: In the case of inputting information to an input picture displayed on a display device 120 by an input user through a coordinate input device 101, a skill judging part 111 calculates the input state of the user as an evaluation value and judges whether the user is a skilled user having mastered input operation or a beginner unskilled in the input operation based on the evaluation value. A display control part 117 displays an input picture for a skilled user or an input picture for a beginner in accordance with the judged result. Since input pictures matched with various levels of users from a beginner up to a skilled user can be provided, an input environment corresponding to each input user out of many unspecified input users in an extremely public place can be realized.
