Title: Sampling method of hydrogen fluoride and its instrument
Inventor: HAGIWARA RIKI
IPC: G01N1/24
Filed: 1982-08-16
Abstract: PURPOSE:To sample simply and make easily the concentration of HF in an environment analyzable, by allowing a definite volume of gas to be treated to flow through a paper filter depositing alkali carbonate, capturing the HF in the gas by the filter. CONSTITUTION:Paper filters 2 are impregnated with an aqueous solution of Na2CO3 or the like, and dried to deposit about 10-15wt% Na2CO3. Plural, for example, three sheets of filters are deposited on a wire gauze, and a packed holder 1 provided with a filter 3 for removing dust is prepared in front of the filters 2. A pipe 5 is attached to an outlet of the holder 1 and conneced to a portable suction pump 6. Then, a definite volume of gas to be measured under an operating environment is passed through the holder 1 by an operator, and the HF in the gas is absorbed and captured. Since the captured HF becomes NaF, it is extracted from the filter 2 to analyze potentiometrically and spectrophotometrically. Thus, an easy sampling and a rapid analysis can be obtd.

Title: Blooming preventing device
Inventor: YAMAGUCHI NAKAO
IPC: H04N5/57
Filed: 1978-11-17
Abstract: PURPOSE:To prevent the blooming without impairing the picture quality by inserting the resistance between the 1st grid of CRT and the earth to detect the 1st grid current and then feeding negatively the detection output back to the emitter of the transistor in the amplifier circuit. CONSTITUTION:Resistance 6 is inserted in series between the 1st grid of CRT4 and the earth to detect current iG flowing to the 1st grid, and the detection output is fed negatively back to the emitter of transistor 1 in the video amplifier circuit via resistance 7. In such constitution, current iG is detected via resistance 6 when beam current iB increases suddenly and the current flows also to the 1st grid, and the increased detection voltage is applied to the emitter of transistor 1 via resistance 7. As a result, the emitter voltage increases with the emitter current decreased. Thus the collector voltage increases to prevent the increment of current iB. Therefore, the blooming can be prevented without impairing the frequency characteristics of the video signal.

Title: Semiconductor integrated circuit wafer and mask for manufacturing the same
Inventor: TAKEGAWA TOUJIROU
IPC: G03F1/54
Filed: 1983-08-04
Abstract: PURPOSE:To facilitate assembly and environmental tests by a method wherein, when a plurality of rectangular chips with different chip sizes are formed on one semiconductor substrate, a plurality of the chips of one type and a plurality of the chips of another type are formed separately with a scribing line at their boundary in such a manner that the two types of chips touch with each other at their corners and vacant regions formed by above method are removed. CONSTITUTION:When chips of LSI-A and chips of LSI-B, which have chip sizes different from each other, are formed on the same semiconductor substrate, at first LSI-A chips are formed above a scribing line, which is used as a boundary, using one type of mask. Then LSI-B chips are formed below the scribing line so as to make corners of LSI-B chips touch the corners of LSI-A chip using another type of mask. Thus, the formation of these LSI chips is made easier. With this method, vacant regions 2 are formed above the scribing line and between LSI-A chips and vacant regions 3 are formed below the scribing line and between LSI- B chips, but these regions are unnecessary parts and cut off at the time of scribing.

Title: Laser printer controller
Inventor: TAKAGISHI KAZUFUMI
IPC: B41J2/44
Filed: 1986-06-20
Abstract: PURPOSE:To shorten the printing time of a laser printer, by arranging an intermediate buffer memory between a receiving buffer memory and a bit map memory then rearranging the receiving buffer data in the order of the bit map memory address and storing it in said intermediate buffer memory, thereby enabling transmission of a print command to a laser printer without waiting the end of description of all print data on a sheet of cut paper into the bit map memory. CONSTITUTION:Dot data are described into a bit map memory 3 by taking out data from an intermediate buffer 6. Since the data are contained in the intermediate buffer 6 while being rearranged such that the receiving buffer data are described sequentially in the order of bit map memory 3 address, the receiving buffer data are described in the order of the bit map memory 3 address. Since the undescribed in the intermediate buffer 6 can be recognized, a print command can be transmitted to a laser printer before the dot data on a sheet of cut paper stored in the bit map memory are completely described.

Title: Fan
Inventor: KISO MATAICHIROU
IPC: F04D29/28
Filed: 1977-11-28
Abstract: PURPOSE:To reduce the noise owing to torsional vibration by fixing both ends of a multi-blade fan to an output shaft through a fixing means and suppressing the vibration about the output shaft. CONSTITUTION:A fan 4 is fixed firmly to an output shaft 3a at one position with a boss 6 and at two positions with small bosses 10, in tatal at three positions. As a result, natural frequency of the fan 4 becomes higher than that of a conventional type one which is fixed at only one position with a boss 6. Therefore, needless to say of the case when the frequency of variable torque does not coincide with the natural frequency of torsion, even when the two coincide with each other, magnitude of the variable torque which acts as external force on the torsional vibration system about the output shaft 3a becomes small effectively for the higher frequency constituents of the variable torpue. Therefore, torsional vibration about the output shaft 3a is reduced and the noise accompanied by the vibration is also reduced.
