Title: Laminated plate and method for inspecting optic axis using it
Inventor: KOBAYASHI SHINJI
IPC: G02B5/30
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To inspect the optical axis of a polarizing plate precisely even visually by arranging the first and second polarizing plates on a light transmitting plate so that the optic axis of the first plate and that of the second plate are line- symmetrical mutually to a standard line. SOLUTION: The first and second polarizing plates 2,3 are arranged in parallel on a light transmitting plate 1, and the optic axes 4, 5 of the plate 2, 3 are line-symmetrical to a reference line 6, and the angle θ1 between the axis 4 and the line 6 is equal to the angle θ2 between the axis 5 and the line 6. To inspect the optic axis of a polarizing plate specimen 8, for example, the specimen 8 is laid on the first and second polarizing plates 2, 3 to overlap each other so that the brightness of the overlapping part 10 of the specimen 8 and the plate 2 is equal to that of the overlapping part 11 of the specimen 8 and the plate 3. Besides, when the plate 2 and the plate 3 are arranged to be adjacent along the reference line 6, the brightness of the overlapping part 10 and the brightness of the part 11 can be compared more easily and more precisely.

Title: Method and device for removing dust
Inventor: OSAWA SEIJI
IPC: B01D46/42
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To regenerate a filter without damaging the surface of the filter by passing a gas containing dust through from the outside of the nearly cylindrical filter to the inside to filter the dust and rotating the filter to blow off the deposited dust with centrifugal force at the time of the regeneration of the filter. SOLUTION: In the case of connecting a dust removing device used for a semiconductor production process to a dust generating source, a gas containing the dust enters into a casing 10 from an introducing port 17 and is passed through a filter 21 in a filter unit 20. At this time, the dust is filtered and remains on the outer periphery side of the filter 21, only the gas is passed through the filter 21, passes a cylindrical member 28 from a vent 25a at a bottom plate 25 and is discharged to the outside of a device from an outlet 18. At the time of regenerating the filter 21, the filter unit 20 is rotated by driving a motor 16. Then, the deposited dust is blown off from the filter 21 by the centrifugal force due to the rotation of the filter 21. The dust broken away from the filter 21 is stored in an under part box 13.

Title: Data transfer interface device
Inventor: KUNO TAKESHI
IPC: G06F13/36
Filed: 1991-08-09
Abstract: PURPOSE:To obtain a data transfer interface device which can increase the data transfer speed and also can improve the CPU availability. CONSTITUTION:The data received successively from the transmission side are latched in sequence by the latches 13a-13d until the data bit width of a CPU 36 reaches the maximum allowable value. When the latches 13a-13d have full scales, an interruption generator 35 transmits an interruption signal to the CPU 36. Receiving the interruption signal, the CPU 36 reads the data out of the latches 13a-13d at one time. Thus the interruption frequency is reduced to the CPU 36 and the data transfer speed is increased. Furthermore it is possible to increase the time when the CPU 36 can be used for other jobs.

Title: Multi-beam optical scanner
Inventor: ICHIHARA KOICHI
IPC: G02B26/10
Filed: 1998-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a multi-beam optical scanner capable of accurately defining a physical position of a light source holding member from a potential difference between a reference potential and a contact point using a conductor with constant resistance without using a starting point sensor. SOLUTION: A conductor 6 having a constant resistance is in contact with a contact point 4 of a light source holding member 2. A potential difference between this contact point and the reference voltage is digitized by a potential difference detector 7 and sent to a main body. The optical holding member 2 is rotated with the operation of an actuator 5, and the contact 4 in contact with the conductor 6 having the constant resistance is also automatically varied in the position. Since the information on these movements is transmitted to the main body at any time, the main body always confirms the position corresponding the potential difference.

Title: Check system for production tool
Inventor: KOMAI YOSHIO
IPC: G06Q50/00
Filed: 1988-09-08
Abstract: PURPOSE:To ensure the smooth progress of a production process by checking previously whether the necessary production tools are registered or not in the production process of works like a printed board unit, etc. CONSTITUTION:When a commanded date for shipment of materials is written into a progress file 17 based on the production order information JSD, a production tool shortage detail file 18 is updated. The contents of the file 18 are printed by a printer 23 and a production tool production instruction slip is produced when the record of the file 18 is produced or updated. Thus a person in charge checks the short production tools based on the tool production instruction slip and gives the instructions to the corresponding departments to produce the relevant work until a limited date. The instruction slip is automatically produced and the short production tools are known before they are actually needed at each site of processes. Thus it is possible to instruct the production and the registration of the short tools in good timing. As a result, the necessary tools are registered before each due process is started and each production process is smoothly carried out with no interruption.

IPC: H01L29/78
Filed: 1986-09-26
Abstract: PURPOSE:To minimize damage to a MOS-type FET element due to radioactive rays and obtain a minute MOS element that is more reliable for a long period by forming a gate pattern of the FET element by using a positive type electron beam or an X-rays resist. CONSTITUTION:A gate oxide film 2 and a polysilicon 3 of a gate electrode material are formed at a silicon substrate 1 and a positive type electron beam resist 4 is adherent on the above polysilicon 3. Then, the irradiation of electron beam 5 is carried out at 2muc/cm<2> by applying acceleration voltage 30 KV to regions other than l1 that is broader by 1-0.2mum than a design gate length l2. Subsequently, a dimension of a resist pattern 6 comes to the design dimension l2: 1.0 mum by using an alkali developing solution with the extension of development time. Finally, a gate electrode 7 is obtained by etching polysilicon during a time of gas plasma including carbon tetrafluoride. As to a change of mutual conductance after testing of direct current impressed electromotive force in a time of 1000 s., it is not affected very much by electron beam exposure in comparison with that of a transistor made of negative resist and in the case of effect on electron beam exposure 10 mum/cm<2> or less, it is almost identical to that due to a device made by lithography system. Moreover, it is preferable for a distance given by l1-l2 to have a range of 0.05-1mum from the processing point of view.

Abstract: PURPOSE:To prevent the shape of electrode wirings from damaging and to simultaneously prevent a passivation film from cracking by forming the thickness of the passivation film 1.8mum or larger, thereby protecting the electrode wirings against the stress of a molding material. CONSTITUTION:The thickness of a passivation film 3 is set to 1.8mum or larger.
