Title: Scanning electron microscope
Inventor: OSE YOICHI
IPC: H01J37/28
Filed: 1992-12-15
Abstract: PURPOSE:To provide a scanning electron microscope in which the yield of a secondary electron can be increased up to 100% and also aberration can be reduced, thereby making it feasible to perform observation with high resolution. CONSTITUTION:A primary electron beam 1 passes through a deflection coil 7 and then is throw on a sample 3. At that time, a magnetic field made by an objective lens is spread over the sample 3 and the upper space and the primary electron beam 1 is focused to a degree of being several nm in diameter. With the primary electron beam thrown on the sample 3, a secondary electron 2 is emitted from the sample 3 with angular distribution. Since the energy of secondary electron 2 is as low as several eV, the secondary electron 2 is twisted about the magnetic flux of the objective lens 5 to go up as it is making spiral motion. The magnetic flux density abruptly goes down apart from the direction of the sample, and the secondary electron is shaked off from the spiral motion to evaporate and then is deflected with the attracting electric field from a secondary electron detector 4 and is caught by the secondary electron detector 4.

Title: Solid image sensor element
Inventor: HAMAZAKI MASAHARU
IPC: H04N5/335
Filed: 1988-12-29
Abstract: PURPOSE:To enable enhancing the sensitivity of an image sensor by extending a first-conductivity-type island region formed around a source region to drain regions. CONSTITUTION:An n-type well region 2 as a semiconductor layer is formed on a p-type silicon substrate 1 having a first-conductivity-type picture element. An n<+> type source region 4 and n<+> type drain regions 5 of the same conductivity type are formed in the surface of said n-type well region 2. A p-type well region 3, a first-conductivity-type island region, is formed around the source region 4 in the surface of the substrate and extended to the drain regions 5. Therefore, depth required for obtaining spectral sensitivity and depth of the island region from the substrate can be set independently by potential formed by the island region. Thereby the spectral sensitivity can be enhanced.

Title: Humidifier
Inventor: GUREN ARAN GUARARUDEI
IPC: B41F7/24
Filed: 1989-12-22
Abstract: PURPOSE: To eliminate a flow of an undesired fluid through a fluid control position to be formed by a nip by obviating a flow of an excess flow fluid part from a circumference of both ends of the nip in an axial direction to a slip roller by collars provided at both axial ends of a pan roller, and transferring to return a liquid of a liquid pan by rotating the collars together with the pan roller. CONSTITUTION: An affinity between a brass collar 30 disposed at an end 15 of a pan roller 12 and a fluid is larger than that between a rubber outer surface of a slip roller 16 and the fluid. Since the affinity between the fluid and the collar 30 is thus large, the collar 30 tends to capture the excess fluid at an end of a nip 18 as the collar 30 rotates together with the roller 12. As the collar 30 continuously rotates together with the roller 12, the fluid captured by the collar 30 is separated from the roller 16, and returned to a fluid pan 14. Thus, the excess fluid at the end of the nip 18 is captured, and separated from the roller 16.

Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To execute a fusion welding under proper energizing conditions in an electric fusion-welding joint and, in addition, two or more times of energization are prevented from being executed. SOLUTION: To an electric fusion-welding joint 1, a condition code 8 corresponding to energizing conditions and an individual code 9, which is individually set to each electric fusion-welding joint 1, are attached. By reading the condition code 8 and the individual code 9 with a bar code reader 11, whether or not the individual code 9 has already been stored in a code memory 16 in a fusion- welding control device 10 is judged. When the individual code 9 has not been stored in the code memory 16, a control circuit 17 supplys a power under the condition corresponding to the condition code 8 from a power source 18 through connecting cables 6 and 7 to the electrodes 4 and 5 of the electric fusion-welding joint 1 so as to execute a fusion-welding by controlling the energization.  Since the individual code 9 at this time has been stored in the code memory 16, even when once more energizization is intended to the same electric fusion-welding joint 1, a energization is not executed and a display by an alarm or the like by means of a display 19 is executed.

The correction circuit 6 is so constructed that the amount of correction can be changed as occasion demands after the correction of linearity is made for a measured distance signal Lo obtained from an arithmetic circuit 5. In order to change the amount of correction by using the data of the memory 64b, in other words, it is needed only to input a correction timing signal to the correction circuit 6 from a circuit 14. Until this correction timing signal is inputted, correction is executed in the ordinary amount of correction. Since the memory 64b is RAM, besides, data being necessary for correction are erased when the power source is cut off and charged again.
