Title: Polyallyl type alcohols and process for production thereof
IPC: C08F8/12
Filed: 1943-01-08
Abstract: Polymeric allyl-type alcohols are made by heating a polymeric carboxylic acid ester of an allyl-type alcohol with a monohydric alcohol and separating the resulting carboxylic acid ester of the monohydric alcohol from the polymeric allyl-type alcohol. Polymeric esters specified are polyallyl formate, acetate, propionate, butyrate, isobutyrate, ethoxyformate, benzoate, phthalate, maleate, a -hydroxyisobutyrate, acetylglycollate, stearate, succinate, glutarate, malonate, phenoxyformate and a -ethoxyacetate; poly-b -methylallyl acetate and methoxyformate; poly-a -methylallyl formate; poly-a -phenylallyl acetate; poly-b -phenylallyl isopropoxyformate; poly-b -chlorallyl acetate; poly-b -ethylallyl acetate; poly-b -methoxyallyl formate, poly di-b -methylallyl adipate; poly-b -cyclohexylallyl acetate.  They may be prepared by heating the monomers in the presence of benzoyl peroxide at 65 DEG  C.  The monohydric alcohol may be methyl, ethyl, n-propyl, isopropyl, sec.-butyl, n-butyl, isobutyl, amyl, hexyl, octyl, allyl, b -methylallyl, b -phenylallyl, propargyl and crotyl alcohols, cyclohexanol, methylcyclohexanol, cyclopentanol and methyl vinyl carbinol.  The reaction may be carried out in the presence of catalysts, e.g. the alcoholates of lithium, sodium, potassium, magnesium, calcium, barium or aluminium.  These catalysts may be removed from the product by conversion to an insoluble salt, e.g. bicarbonate or sulphate, by treatment with carbon dioxide or sulphuric acid respectively.  The crude product is purified by dissolving it in water or methyl, ethyl or isopropyl alcohols and treating with a non-solvent, e.g. acetone, methyl ethyl ketone, benzene, toluene, hexane, heptane, naphtha, ethyl or isopropyl ethers.  Preferably, the polyallyl type alcohol is separated from the reaction mixture by extraction with a solvent, volatilization, vaporization, or distillation, which may be azeotropic.  The products may be used as adhesives, sizes, lubricants and impregnating agents for paper.  They may be reacted with polycarboxylic acids or anhydrides to form alkyd resins, with unsaturated acids of drying oils to form drying oils, with aldehydes to form acetals or with nitric acid to form explosive nitrates.  Specification 566,344 and U.S.A.  Specification 2,164,188 are referred to.

Abstract: 745,375. Governors; engine valve and stop-gear. KURETSCHKA, F. Jan. 13, 1953 [Feb. 6, 1952], No. 982/53. Classes 57, 122(2) and 122(4) A governor 2 regulates the speed of a reciprocating steam engine by axially displacing a cam 4 to alter the admission period of an inlet valve controlled by the cam, the relationship between the axial displacement of the cam 4 and the alteration of the admission period being non-linear. The governor 2 is mounted on a shaft 1 driven by the engine crankshaft and connected by bevel gears 6 7 to a cam shaft 3 carrying the cam 4 which oscillates a follower 16 mounted on a second-order lever in operative engagement with the rod of the inlet valve. When the engine is running at low speed the inlet valve is held open for a relatively long period by the profile at F while an increase in engine speed causes the governor to act through a lever 13, 14 to displace the cam shaft to the right so that the inlet valve is held open for a shorter period by a profile such as C. Toprevent the engine running at excessive speed, the .left-hand portion of the cam 4 has a circular profile which does not open the inlet' valve at all. The time at which this valve opens remains unchanged with the axial position of the cam while the time at which it closes is varied non- linearly as shown by the lines 23b, 23c to provide a variation in the sensitivity of regulation over the speed range of the engine. Engine stop-gear. If the engine speed rises beyond its permitted maximum, for example as a result of sudden removal of the load, the governor 2 causes a striker 24 to rock a two-armed lever 26 anticlockwise and release a weight 28 which closes a valve 30 in the steam supply pipe.

Title: Memory having ferroelectric memory cell and reading method of ferroelectric memory
Inventor: NISHIMURA AKITOSHI
IPC: G11C11/22
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To realize a small cell area by including a ferro-electric capacitor, a gate connected to the word line and a path transistor having a current transfer terminal connected between respective drive line connection and bit line connection in each ferroelectric memory cell and then impressing pulses of a couple of signs opposed with each other to the drive line connection of cell. SOLUTION: The bit line and drive line are charged previously to a half voltage of the power supply voltage and when the word line becomes high level, the drive line is driven with a complicated waveform. Immediately after the word line becomes high level, the drive line is driven by Vcc. Thereafter, the drive line drops to the voltage lower than the bias voltage and the bit line voltage is preferably higher level than the DC bias level. The voltage impressed in this stage sets the natural polarization of ferroelectric film almost to zero as the preparation for final updating of cell condition to reset. Thereafter, the drive line is reset to the DC bias level.

Abstract: PROBLEM TO BE SOLVED: To simplify and clarify the design by presuming a shear failure type cotter formed between structural members and using high tensile strength jointing members. SOLUTION: A recessed portion is formed in a column 1 and a projected portion is formed in a beam 2. The projected portion in the beam 2 is fitted to the recessed portion in column 1, and a shear failure type cotter 5 is formed and the column 1 and beam 2 are jointed together. In addition, the column 1 and beam 2 are jointed by high tensile strength jointing members 3 such as high strength steel bars or PC steel rods, and a gap filler 4 comprising urethane resin or the like is placed between the jointing member 3 and column 1 and beam 2. The cotter 5 has a shear failure, then the shear failure surface 12 becomes a rough surface 14, and the place of a compressed surface 13 of a ruptured surface 12 becomes a shear resistance surface 121 with the rough surface 14.  Moreover, a compressive constraint force acts to the shear resistance surface 121 in order to balance with the tensile force of the jointing member 3, thereby blocking a deviation between the column 1 and beam 2 by the shear resistance 122. In this way, the design can be simplified.
