Title: Quadrupole mass spectrometer
Inventor: TAKEDA TSUNEZOU
IPC: H01J49/42
Filed: 1983-12-29
Abstract: PURPOSE:To decrease the analyzer's burden in the stage of adjusting a mass spectrometer by measuring preliminarily the movement of the center of a mass peak when resolving power is changed and correcting automatically the mass change according to setting of the resolving power on the data thereof. CONSTITUTION:A CPUC feeds a control signal to a quadrupole power source E to change a DC voltage U and a high-frequency AC voltage having amplitude V. The CPUC multiplies a coefft. K by the data of the amplitude V to calculate mass M from the value V by M=KV and displays the value M on a display device D. Since the value K changes with the setting of resolving power, the data on the relation K=f(R) between the resolving power R and K is actually measured and is preliminarily stored in the CPUC and the mass M is immediately dispalyed as M=f(R)V according to the set R. R is determined by U/V and therefore M is displayed as M=g(U/V)V as the data for the set resolving power. g(U/V) is preliminarily stored as g(U/V)=A(U/V)<2>+B(U/V)+C by determining A, B, C with the actual measurement.

Filed: 1987-09-30
Abstract: PURPOSE:To set an optional test speed with analog sensation and improve the operability by providing a knob, a rotary encoder, a decoder, etc., and enabling the optional test speed to be set. CONSTITUTION:As the know 10 is displaced, a decoder 12 outputs an up-pulse signal or down-pulse signal corresponding to the displacement position according to a phase signal outputted by the rotary encoder 11. Then a binary code signal is outputted by counting the pulses of the up- or down-pulse signal and a microcomputer MC computes a speed setting signal matching with the binary code signal. Namely, the knob 10 is rotated so as to a desired test speed to be set over a look at a test speed displayed on a display 15, and fixed at a desired place. In this state, a motor 6 is driven to accurately test characteristics of various materials while setting the desired test speed artificially and freely by the continuous displacement.

Abstract: PURPOSE:To obtain the titled compound of high purity and low hue with very little increase in viscosity of products by partially polymerized impurities, etc., by esterifying acrylic acid with a polyhydric alcohol in the presence of an acid catalyst while changing the pressure in three stages. CONSTITUTION:The esterification reaction of acrylic acid with a polyhydric alcohol, e.g. 4,4'-bishydroxyethylbisphenol A, etc., is started in the presence of an acid catalyst, e.g. p-toluenesulfonic acid, and a polymerization inhibitor, e.g. hydroquinone, under pressure. At a stage in which the reaction proceeds to 15-35% conversion, the reaction mixture is subjected to ordinary pressure, cooled and washed with an aqueous solution of an alkali to remove impurities, e.g. catalyst, etc. At a stage in which the reaction further proceeds to 60-80% conversion, the reaction mixture is subjected to reduced pressure at 70-110 deg.C to remove the solvent and carry out esterification reaction. Thereby, the aimed high-purity compound useful as a raw material for ultraviolet curing inks or coating materials is obtained. EFFECT:A photo-setting resin having good reactivity is obtained with little deterioration in esterification ratio by mutual dimerization of acrylic acid.

Filed: 1989-09-26
Abstract: PURPOSE:To change the capacity of a discharge pressure working region so as to absorb the pulsation of a discharge pressure by containing a pulsation absorbing member, formed out of an elastic material having indipendent foams, in the discharge pressure working region of a pump. CONSTITUTION:On a discharge pressure working region in a pump housing 1, for example, in a doughnut-like discharge chamber 12, a doughnut-like pulsation absorbing member 13 is fixed by a ring 14. The pulsation absorbing member 13 is formed out of an elastic material such as rubber, and a number of independent foams that do not break during the use of the pump are formed inside. When the pulsation is generated in the discharge pressure due to the working of the pump, pulsation pressure is added to the pulsation absorbing member 13 in the discharge chamber 12, and each independent foam in the pulsation absorbing member 13 is compressed and expanded, the volume of the pulsation absorbing member 13 is changed, whereby the capacity of the discharge chamber 12 is changed and the pulsation of the discharge pressure is absorbed thereby. The absorption of the discharge pressure pulsation is thus achieved without enlarging the capacity of the discharge chamber 12, and the pulsation reduction can be achieved for the purpose of noise reduction.
