Title: Wet type waste gas desulfurization equipment
Inventor: KIKUCHI TORAO
IPC: B01D53/18
Filed: 1988-03-29
Abstract: PURPOSE:To prevent clogging of a slurry discharge part due to scale by providing a protector for inhibiting the passage of large scale to the aperture of the slurry discharge pipe of the connection part of the lower part of a cooling tower. CONSTITUTION:In a wet type waste gas desulfurization equipment in which slurry of calcium compd. and magnesium compd. is utilized as an absorbent, a protector 10 is fitted so as to cover a discharge port of slurry fed from a sump part 2 of the lower part of a cooling tower 1 and formed into a network structure and a latticelike structure, etc., wherein absorbent slurry and small scale are passed but large scale is not passed therethrough. Further the protector 10 is formed into prescribed height and made of corrosion resistant material such as stainless steel and ceramic and also replaced at a time of routine inspection of the equipment. As a result, the sudden clogging of the discharge pipe 7 due to peeling and fall of scale stuck on the cooling tower 1 and the inner wall of the sump part 2 can be prevented.

Title: Floating type magnetic head and magnetic recording and reproducing method
Inventor: HAMANAKA HIDEKI
IPC: G11B21/21
Filed: 1991-03-15
Abstract: PURPOSE:To uniform the floating amount of a magnetic head, to prevent the occurrence of wear and to improve recording density by forming the slider of the magnetic head into the specified length and height. CONSTITUTION:The floating amount of a magnetic head 1 is set at 0.13mum or below. When a slider 11 of the magnetic head 1 is set so as to have a length L in the track direction of a front surface and a height H between the tip of an air bearing surface and the rear end of the slider, the correlation between L and H is 1<=L/H<=3.7. By setting L and H as shown in the expression, the gravity of the slider can be elevated. Accordingly, the moment generated by a force of the air flowing to a reading side acting on the slider 11 balances with the moment of the floating force acting on a front surface which acts on the gravity and therefore, a front surface 111 of the slider 11 takes an attitude approximately parallel with the recording surface or tilted forward while floating. Thus, the floating amount can be reduced compared with that in a conventional device and the recording density on the recording surface can be improved.

IPC: G01S3/782
Filed: 1984-04-18
Abstract: PURPOSE:To detect the position of a bright point to be measured by blinking the objective bright point synchronously with a pulse signal which synchronizes with variation of background light and at a different period from that of the pulse signal. CONSTITUTION:A synchronizing pulse generator 8 inputs an AC input signal S01 supplied to a lighting device 7 and outputs a pulse signal S02 synchronizing with the signal S01, and the signal S02 synchronizes with the background light 5. An optical position detector 1 measures the light quantity distribution within a detection visual field synchronously with the signal S02 and the objective bright point 2 at a measurement position is blinked with a pulse signal S03 which is frequency-divided by two through a pulse period converter 9. For the purpose, the detector 1 measures the bright point 2 and background light 5 at time t1 and measures only the background light 5 at next time t2; the background color 5 is equal at the time t1 and time t2 because the time t1 and time t2 synchronize with the background light 5. Consequently, the accurate signal S3 of the position of the bright point which is not influenced by the background light 5 of the lighting 7 is obtained.

Title: Method to recover fluidity of fluidized bed catalyst for production of phthalic anhydride
Inventor: NOBUSAWA TATSUYA
IPC: B01J38/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To effectively recover the fluid performance which is important for a fluidized bed catalyst for the production of phthalic anhydride when the fluid performance of the catalyst decreases, by draining a part of the catalyst from a fluidized bed reactor, pulverizing the catalyst, controlling the particle size of the pulverized catalyst and then supplying the catalyst again to the reactor. SOLUTION: In a fluidized bed catalyst used for the production of phthalic anhydride, such problems occur that the active component which impregnates the catalyst bleeds out on the outer surfaces of catalyst particles and the component causes modification with time to increase its viscosity and causes aggregation of the catalyst or decrease in the fluid performance. In this case, the fluid performance is recovered by draining a part of the catalyst from the fluidizing bed reactor, pulverizing the catalyst, and then supplying the pulverized catalyst having <15μm particle size again into the reactor. In this method, the average particle size of the fluidizing bed catalyst before pulverization is preferably >=30μm.  The amt. of the pulverized catalyst to be supplied again to the reactor is preferably controlled to >=0.1wt.% of the whole amt. of the catalyst in the reactor, and more preferably to a range from 0.1 to 25wt.%.

Title: Facsimile receiver
Inventor: SUNAGA MOTOHARU
IPC: H04N1/32
Filed: 1979-06-19
Abstract: PURPOSE:To eliminate the discontinuation of recording and thus increase the receiving efficiency by securing the continuation of the receiving action in case the end of the recording paper is detected, thus increasing the business work efficiency. CONSTITUTION:Recording paper detector 5 is provided at the position which is apart by l from the central position of recording head 3. The space l is set nearly identical to or larger than the maximum original length of the transmitter. Thus the signal deciding whether the reception is possible or not for the transmitting original is sent to the transmitter side according to the presence or absence of the record end detection signal sent from detector 5. Accordingly, one sheet of transmitted original can always be received and recorded completely by transmitting the above signal. As a result, such inconvenience in that the recording paper ends in the course of recording to discontinue the receiving action can be solved.
