Title: Electronic disposal of water
Inventor: SUZUKI TAKAHIRO
IPC: C02F5/00
Filed: 1980-03-14
Abstract: PURPOSE: To electronically treat water so as not to cause generation of rusts or scales, by arranging a couple of electrodes in a water feeding pipe, charging D.C. potential lower than water electrolysis voltage between both of the electrodes, and supplying a low current.  
     CONSTITUTION: D.C. power source 3 is arranged so as to electrically connect an outside metal pipe 1 to an inside metal pipe 2. A potential ES of the source 3 is determined to be lower than water electrolysis voltage. The low potential generates such a weak electric field that polar molecules in a solution oriented and water molecules are strained. The D.C. potential charged between the electrodes facilitates an oxidation-reduction reaction and reduces a Ca 2+  concentration. Consequently, water is electronically treated so as not to cause generation of rusts or scales, and a life of a line pipe in a building or factory can be prolonged.

Title: Transmission gear of bi-axial extruding machine
Inventor: SAWA KOHEI
IPC: B29C48/405
Filed: 1989-02-09
Abstract: PURPOSE:To accomplish power-up by coupling No.1 screw shaft with a drive shaft, transmitting rotation from a gear fixed on this drive shaft to No.1 idler shaft and No.2 idler shaft, and transmitting torque through gears from the two idler shafts to No.2 screw shaft. CONSTITUTION:No.1 screw shaft 7 is coupled with the driving shaft 9 of a driver device 8, and No.1 gear 1 is fixed. Torque is transmitted from No.2 gear 2, No.1 idler shaft 11, and No.4 gear 4, which are meshing with the No.1 gear 1, to No.6 gear fixed on No.2 screw shaft 10. Further, from No.3 gear meshing with the No.1 gear 1 the torque is transmitted to No.6 gear through No.2 idler shaft and No.5 gear. The No.2-5 gears have the same number of cogs, while the No.1 and No.6 gears have the same. Accordingly the No.2 screw shaft 10 accepts transmitted torque from both idler shafts, No.1 and No.2, which allows lessening of the cog width in the biaxial extruding machine concerned and accomplishes power-up therein.

Title: Production of poly(hydroxystyrene)
Inventor: WATANABE OSAMU
IPC: C08F8/12
Filed: 1991-01-31
Abstract: PURPOSE:To obtain a monodisperse poly(hydroxystyrene) having a desired molecular weight by anionically polymerizing a specific monomer and then eliminating dimethylphenylcarbinyldimethylsilyl groups from the resulting polymer. CONSTITUTION:A monomer of formula I is anionically polymerized in the presence of a living anionic polymerization initiator in an organic solvent at -78 deg.C to the boiling point of the solvent for 10min to 7hr thereby to obtain a living polymer which is poly(p-vinylphenoxydimethylphenylcarbinyldimethylsilane) made up of the unit of formula II. An acid is added dropwise to this polymer in a mixed solvent composed of dioxane, acetone, acetonitrile, benzene, etc., thereby to cleave each pendant group at the ether bond to which the dimethylphenylcarbinyldimethylsilyl group is linked. Thus, a poly(hydroxystyrene) is obtained which has the phenol moiety-containing structural unit of formula III.

Title: Electronic computer
Inventor: FUKUMURA MASAAKI
IPC: G06F1/00
Filed: 1980-03-13
Abstract: PURPOSE:To secure an automatic announcement of the program PG to be processed on that day, by providing a comment table to which the comment and the date of its execution of each processed PG are preset. CONSTITUTION:The input data supplied from the keyboard 12 puts the date data of the processed PG into the A register RG22 via the input controller CT21 and address CT23. At the same time, the comment and the date of its execution of the PG to be processed are written previously into the comment table TB14A. The date data of TB14A is put into the comparator 26 via BRG24 to be compared with the date data of RG22. The circuit 26 delivers the coincidence signal to the gates 25a and 25b when a coincidence is obtained for the date data between RG22 and RG24, and thus the gate is opened to send both the date data and the comment data given from TB14A to the display memory 28. Then the output of the memory 28 is displayed at the display part 13 via the display CT29. The circuit 26 transmits the end signal to CT23 when a comparing action is over, and thus CT23 designates the next address of TB14A.

Title: Phase locked loop circuit
Inventor: IRIE KOICHI
IPC: H03L7/06
Filed: 1990-02-13
Abstract: PURPOSE:To reduce phase noise while keeping a pulling-in frequency range wide as it is by applying the pulling-in operation when a difference between frequencies of a reference signal and a frequency dividing signal exceeds the pulling-in frequency range of a phase detector. CONSTITUTION:When a SW1 is turned on, the oscillating frequency fout of a voltage controlled oscillator 1 is lowered, a frequency fv (=fout/N) is lowered, and when a SW2 is turned on, the oscillating frequency fout of the voltage controlled oscillator 1 gets higher and the frequency fv gets higher. When both SW1, 2 are turned off, PLL(phase locked loop) operation is implemented via a phase detector 3. Thus, when a frequency Mf0 is set corresponding to the pulling-in frequency range of the multiplier type phase detector 3, the difference of frequencies of the reference signal and the frequency dividing signal exceeds the pulling-in frequency range of the phase detector 3, then the pulling-in operation is implemented. Thus, the pulling-in frequency range is expanded and the phase noise is reduced.

Filed: 1981-03-06
Abstract: PURPOSE:To enable to positively feed while separating sheet form copies one by one by a method wherein the sheet form copies are set with their rear edge parts curved, and feed the copies sequentially from the ones on the inner side. CONSTITUTION:The rear edge parts of the sheet form copies 11 are clamped from below and above so as to prevent them from staggering, and are curved downwards to form a loop on the opposite side to the feeding position.

Filed: 1987-02-17
Abstract: PURPOSE:To increase the amt. of photosensitive planographic printing plates which can be processed per unit developing soln. by immersing the printing plate into the developing soln. to swell the photosensitive layer to be removed and separating the developing soln. then rubbing away the photosensitive layer in water, thereby developing the printing plate. CONSTITUTION:The photosensitive planographic printing plate having the photosensitive compsn. layer essentially consisting of a photosensitive diazo resin and lipophilic high-polymer compd. on an aluminum sheet is immersed into the developing soln. to swell the photosensitive layer to be removed without dissolving the same. After the developing soln. is separated therefrom, the photosensitive layer is rubbed away from the aluminum sheet in the water and the development is thereby executed. Since the elution of the photosensitive layer into the developing soln. is thereby substantially prevented, the activity of the developing soln. is maintained without being degraded The amt. of the photosensitive layers which can be developed per unit developing soln. is thereby greatly increased.

Abstract: PURPOSE:To improve an S/N without being affected adversely by picked up noise from an erasure core even if a track shift arises by providing the erasure core with an additional one, or adding a transformer circuit to the erase coil of the erasure core and connecting it to the reproduction coil of a recording and reproducing core. CONSTITUTION:The additional coil 10 is inserted into the erasure core 4 separate from the erasure coil 6. A signal VE' having the same amplitude as that of a VE with a reverse phase of 180 deg. of the waveform of the signal VE is read out of the additional coil 10, which is connected to a recording and reproducing coil 3. Then each signal is added to offset the waveform of the amplitude VE, and the S/N is improved. In terms of the winding direction of the additional coil 10, the flux direction of a broken line interlinking the additional coil 10 with the flux picked up from an erasure core hollow 8 is opposite to that of an alternate long and short dash line interlinking the recording and reproduction coil 3. When the winding direction of the additional coil 10 is equal to that of the recording and reproducing coil 3, the waveform VE' different in phase from the VE by 180 deg. can be obtained.
