Title: Method of detecting n-type conversion in semiconductor device thermal oxidizing process
Inventor: TAKAYA KENJI
IPC: G01N27/00
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To avoid deteriorating characteristics of a semiconductor device by adding an ion implanting step for introducing a p-type impurity to detect the n-type conversion. SOLUTION: An n-type Si wafer 10 is thermally oxidized by heaters 61, 62 in a thermal oxidizing step, B is implanted at a low dose in an ion implanting step to produce a B ion implanted region (n-type) in an n-type substrate. The oxidizing step to produce the n-type region results in that the resistance of this region rises. After an etching step of the oxidized film the sheet resistance is measured to detect the n-type conversion due to P contamination, etc., at a high sensitivity. Thus it is possible to avoid deteriorating characteristics of a semiconductor device.

Title: Method for deciding packet transfer route and node equipment
Inventor: YAMATO KATSUMI
IPC: H04L45/28
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain better transfer quality by changing the priority of a 1st route whose priority has been placed lower and a 2nd route whose priority has been placed higher in the case that transfer quality of 1st communication information to be transferred with low priority does not meet 1st quality or the like. SOLUTION: A scheduling section 15 conducts cell transmission control in a way that object cells are transmitted immediately when the cells are stored in a CBR container queue 12 and cells stored in a UBR cell container queue 13 are transmitted so long as no cell is stored in the queue 12. Since there is a possibility that a large cell transfer delay is caused from a termination point of the UBR cell container queue 13 to another termination point, a transfer route for cells which are transferred by using a same route and requires the service with high priority is changed different from a transfer route of cells requiring the service with low priority in order to prevent the cell transfer delay requiring the service with low priority from being increased.

Title: Spectacles for stereoscopic image
Inventor: SHIMADA SATOSHI
IPC: G02B30/25
Filed: 1993-08-31
Abstract: PURPOSE:To observe a stereoscopic image without the sense of incompatibility by respectively providing view limiting frames at the polarizing filter parts for left and right eyes of the spectacles for stereoscopic image to observe a laterally bisected monitor display picture. CONSTITUTION:Since crossing right and left pictures R and L displayed through left and right side areas 23A and 23B of a polarizing filter 23 mounted at a monitor are observed by right and left eyes through polarizing filters 33 for right and left eyes of the spectacles for stereoscopic image, a stereoscopic image G can be observed at that crossing position. At such a time, since only the right picture R reaches the right eye and only the left picture L reaches the left eye by providing view limit frames 110A and 110B, only the stereoscopic image can be observed without observing unnatural images around the stereoscopic image G. Further, since the left and right pictures L and R are separately displayed by laterally bisecting the monitor, the stereoscopic image can be observed with the sense of a planar image even when observing the monitor without mounting the spectacles for stereoscopic image.

Title: Cooler for electronic component
Inventor: KUROSAKI HIDEKI
IPC: F25D1/00
Filed: 1992-09-09
Abstract: PURPOSE:To allow cooling even if the air flow path is narrow and the flow path resistance is high by fixing a centrifugal cooling fan directly to an electronic component thereby increasing suction pressure and delivery pressure. CONSTITUTION:A centrifugal fan 10 and a drive motor 6 therefor are fixed directly to an electronic component 7 requiring cooling. The centrifugal fan 10 comprises a shaft 3 for coupling a runner 1 to the motor 6, and a casing having an appropriate inner flow path.

Consequently, the centrifugal fan 10 produces high pressure difference between suction pressure and delivery pressure. Furthermore, suction and delivery air flow is increased resulting in sufficient cooling.
