Title: Scan system
Inventor: MANO OMIHIRO
IPC: G01R31/28
Filed: 1985-03-25
Abstract: PURPOSE:To detect accurately the 1-bit errors produced simultaneously in plural synthesized scan paths by synthesizing the outputs of scan paths through an exclusive OR and comparing this synthesized path output with the prescribed expected value for checking. CONSTITUTION:The test signal set previously as a normal working state is applied to the necessary input of an integrated circuit LSI. Then the shift control signal 45 is set at '1' and therefore the LSI is changed to a test mode. Thus three scan paths are activated. Then a clock 40 is supplied to extract the signal that secured an exclusive OR of these scan paths to the outside from a scan-out output 60. This signal is compared with the prescribed expected value. Thus it is possible to check whether or not the flip-flops 1-11 set inside the LSI are holding the correct logic values. The logic '0' and '0' are added to the scan path selection signals 55 and 56 respectively for output of the exclusive OR of all scan paths.

Title: Semiconductor light emitting element
Inventor: UCHIDA KENJI
IPC: H01S5/343
Filed: 1995-03-20
Abstract: PURPOSE: To provide a semiconductor light emitting element from which light rays having arbitrary wavelengths can be obtained independently or simultaneously even when the light emitting element is operated at a high output. CONSTITUTION: Firstly, light emitting element structures having p-n junctions are independently formed on the front and rear surfaces of a substrate 1 by independently forming nitride compound semiconductor layers on the surfaces at a high temperature and low temperature by using the organometallic vapor phase growth method. Then a light emitting element structure is formed on the substrate which is transparent against light rays from active layers 4 and 11. After the light emitting element structures are formed on the front and rear surfaces of the substrate, the compositions of the active layers 4 and 11 of the element structures are made different from each other. Therefore, different colors of light rays can be mixed by multiplexing the wavelengths of the light rays over a wide wavelength range by controlling the injection current ratio when the light emitting element structures having different light emitting wavelengths are independently formed on the front and rear surface of the substrate.

Title: Information signal recording and reproducing device
Inventor: FUJITA KOJI
IPC: G11B15/46
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To simplify mechanism and to reduce damage to a tape by employing a direct drive that directly connects a reel and a motor in helical scanning type recording. SOLUTION: The capstanless constant speed control and tension control of a tape are performed by controlling each motor 9, 3 for a take-up and a supply reel at an angular velocity in accordance with a wound radius of the tape at a particular point of time. The wound radius of the tape is calculated from each angular velocity of the take-up and the supply reel 7, 1 against the total winding quantity of the tape. The total winding quantity of the tape can be calculated on a known hub radius and the angular velocity at the start or the end of the tape. The detection of the reel motor speed requires a very high sample frequency in the specification; therefore, a magnetic detector is arranged at a space not more than the magnetized space of a magnetizing layer in the generator, thereby enabling a signal to be obtained in a seemingly multiplied frequency.

Title: Piping leakage inspecting implement
Inventor: MIZUGUCHI NORIO
IPC: G01M3/28
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To reduce an amount of water wastefully flowing out from a pipe by improving mounting operability at the pipe. SOLUTION: A pipe P inserted into a cylindrical body 10 is locked in a removal restricting state by a locking means 31. Thereafter, water is supplied to a piping passage, and when the water flows out, an opening/closing valve 32 is closed, and the presence or absence of leakage water at the passage is inspected in this state. Thus, the pipe P can be connected merely by inserting it into the body 10. Since the valve 32 is provided, it is not necessary to supply water to the passage when it is mounted at the pipe P, and mounting at the pipe P may not be disturbed, and an amount of the water wastefully flowing out when mounted can be suppressed to a minimum.

Title: Method for encoding and decoding image

IPC: H04N19/50
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To perform a division processing by a shift arithmetic operation by appropriately selecting the coordinate of a representative point at the time of performing global motion compensation. SOLUTION: In the case of using linear interplation and extrapolation, the representative points are not turned to points positioned at the corner of an image 601 but turned to the points 602-604 positioned at (i, j), (i+p, j) and (i, j+q) on condition that (i), (5), (p) and (q) are integers. At the time, the points 602-604 can be present inside the image and present at the outside. In such a manner, the processing of division in the global motion compensation is replaced with the shift arithmetic operation of binary numbers. Thus, the processing of the division in the predictive image synthesis processing of the global motion compensation is substituted by the shift arithmetic operation and the processing by software and dedicated hardware is simplified.

Abstract: PURPOSE:To decrease the capacity of a purification plant and to make possible the economization of driving power and the curtailing of pipings and installations by providing a branch pipe to a pipeline for the water delivered by a lifting pump from a scale pit and connecting directly the branch pipe to a release port for flushing water. CONSTITUTION:Part of the water delivered from the lifting pump 13 flows through a lifting pipe 14 into the branch pipe 1 and flows through the release port 7a for the flushing water from which the water flows as the flushing water 7 in a trough and enters a water collecting trough 10 while pushing away a cutter scale 6. The water is then contained into the scale pit 12 by passing through a water collecting pipe 11. The scale 6 settles on the bottom of the pit 12 and is separated from the water. The water is sucked by the pump 13 and is delivered to the lifting pipe 14 by which the water is again passed through the pipe 1 and is released therefrom as the flushing water 7. On the other hand, the water past a throttle valve of the pipe 14 passes through the purification plant 8 where the water is used as machine cooling water 17 and spraying water 18. The water is thereafter recovered into the pit 12.
