Title: Production of gypsum
Inventor: YAMAKI TETSUO
IPC: C04B11/26
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To improve productivity and quality such as dehydrating property and fluidity by adding a calcium compound and sodium hydroxide into a solution containing sulfuric acid and hydrochloric acid respectively having a specific concentration and depositing coarse particles. SOLUTION: A gypsum dehydrate having 100-150 μm average particle diameter is obtained by controlling the concentration of sulfuric acid and hydrochloric acid respectively to 150-400 g/l and 3-20 g/l and using the calcium compound such as calcium carbonate and sodium hydroxide. The method is capable of being applied for a waste acid containing sulfuric acid and hydrochloric acid, which is discharged from a sulfuric acid plant in copper refining. As a method using no sodium hydroxide, gypsum dehydrate having 100-150 μm average particle diameter is obtained by adding the calcium compound in >=3 stages into a solution containing 150-400 g/l sulfuric acid. When the quantity of the calcium compound necessary in this method is defined as 100%, the adding quantity in each stage is controlled preferably to 30-40% in a 1st stage, 30-40% in a 2nd stage and 25-30% in a 3rd stage.  The temp. of the solution in any method is set to 30-100 deg.C.

Title: Saturable coil for magnetic switch
Inventor: FUJII TAKASHI
IPC: H01F17/06
Filed: 1989-10-07
Abstract: PURPOSE:To acquire a saturable coil for a magnetic switch having excellent switching characteristics by forming one end edge in the coil direction slightly inside an end edge of an amorphous magnetic body and by projecting the other end edge slightly outside the amorphous magnetic body. CONSTITUTION:One end edge 51 of a wiring direction O1 of an insulating film 5 is inside an end edge 41 of an amorphous magnetic body 4 by  W21. The other end edge 52 projects outside an end edge 42 of the amorphous magnetic body 4 by  W22. Thereby, the end edge 41 of the amorphous magnetic body 4 comes into direct contact with a radiation medium such as air or oil wherein the core is placed at one end edge of the wiring direction O1. Accordingly, cooling effect against the amorphous magnetic body 4 is improved and a temperature rise is restrained. A saturable coil for a magnetic switch having good switch properties can be acquired in this way.

Abstract: PURPOSE:To uniform a desired light transmission state throughout an entire-picture scan by applying a plus and minus AC voltage which has the composite waveform of voltage waveforms applied to scanning electrodes and does not exceed the threshold value of ferroelectric liquid crystal regardless of display contents. CONSTITUTION:A liquid crystal element formed by sandwiching ferroelectric liquid crystal between a couple of substrates having electrodes is driven on a time-division basis by being scanned in line sequence.

The crest value of the 2nd voltage pulse is set smaller than the threshold value of the liquid crystal and larger than the saturation value to select a light transmission or cutoff state. At this time, the difference in crest values between the 1st and the 2nd voltage pulses is equalized regardless of the light transmission and cutoff state and the plus and negative AC voltage which has the absolute value of the difference in crest value between the 1st and the 2nd voltage pulses is applied in a nonselection period.
