Abstract: PURPOSE:The titled crystals that gives a diffraction diagram with a peak at a specific diffraction angle in the powder X-ray diffractormetry using Cu-Kalpha rays, thus showing good solid-liquid separationh and eminently improved heat load in the crystal collection process and blocking troubles. CONSTITUTION:In the powder X-ray diffractormetry using Cu-Kalpha rays, the objective columnar crystals of L-cystine gives a diffraction diagram with two peaks at about 16.2 deg. and about 30 deg. of its diffraction angles (2theta). The crystals are obtained by crystallization of a low-concentration solution of high-purity L- cystine (5-7g/dl) which results from the hydrolysis of human hairs with a mineral acid such as sulfuric acid at a temperature as high as 50-80 deg.C. The crystals are metastable and converts into the known plate crystals, when it is added to a saturated aqueous solution of L-cystine and the solution is stood at 40 deg.C for 20hr. EFFECT:The dried product is prevented from flying away, further its specific volume becomes small and cinvenient to transportation and storage.

Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To provide new magnetic bar reading method, reading processor and magnetic card capable of preventing the carrying speed irregularity of a card from being influenced. SOLUTION: A recording track constituted of a magnetic bar having two kinds of width is read out by a composite magnetic head 1 having two gaps and whether the width of the magnetic bar is larger than a distance between two gaps or not is discriminated from the synthetic waveform of read outputs of two cores. Two kinds of read outputs VR1, VR2 can be obtained by one track. Since a delay corresponding to the distance L between two gaps is generated between the output voltage values VR1, VR2, the synthetic waveform VR1+VR2 of the output voltage values VR1, VR2 has an inherent waveform in accordance with the width K of the magnetic bar. The width K of the magnetic bar is judged based on the inherent waveform and a magnetic bar signal is demodulated.

CONSTITUTION:A titled lens is constituted of the positive 1st and the 2nd lenses, and the overall length SIGMAd is determined within the range shown by the equation 1. The face on the incident side of the 1st lens is made of an aspherical surface of which the part near the vertix thereof is approximate. The face on the incident side of the 2nd lens is the aspherical surface expressed by the equation 2 when the distance from the optional point on the face up to the tangential plane at the vertex is defined as x. In the equations, y is the distance from the optional point up to the optical axis, E, F, G are respectively the coeffts. of aspherical surface at the 4th, 6th and 8th terms. The lens is thus formed to have overall length (d1+d2+d3) as small as <=0.9f. The equations 3, 4 are further satisfied to decrease the bluge of mainly the spherical aberration and sine conditions. The thickness d3 of the 2nd lens is determined to satisfy the equation 5 whereby the working stance WD is increased and various aberrations are compensated.

Abstract: PURPOSE:To decrease the liquid crystal sticking to liquid crystal cells at the time of injection by using a liftable arm formed partly with a groove for contg. the liquid crystal to bring injection holes into contact with the build-up part of the liquid crystal in the groove and increasing the air pressure successively. CONSTITUTION:Plural sheets of the liquid crystal cells 13 are housed vertically in a stocker 17 in such a manner that the liquid crystal injection holes 18 face downward. The cells are hung in a vacuum vessel 12 and the liftable arm 14 is immersed in a liquid crystal tank 15 and is vacuum evacuated in this state to expel the air in the liquid crystal cells 13. The liquid crystal 16 is held built up by surface tension in the groove 19 on the arm 14. The high vacuum is maintained in the cells and, therefore, the liquid crystal is successively force-fed into the liquid crystal cells in the groove 19 through the holes 18 of the degree of vacuum in the vessel 12 is lowered down to the atmospheric pressure after the liquid crystal comes into perfect contact with the part near the injection holes. The amt. of the liquid crystal to be used is thereby decreased and since the liquid crystal is injected into the cells by the mere contact with the part near the injection holes, the intrusion of impurities, etc., is decreased.

Title: Generator for compressed gas
Inventor: BUORUFUGANGU KARUTENTEERERU
IPC: B60T17/02
Filed: 1982-09-14
Abstract: A pressure gas generating system including the compressor which is switched to a no-load condition when a predetermined pressure level is reached. The system employs either a regulator or a governor to allow the free exchange of gas between the suction chamber and the compression chamber to prevent the development of high temperatures. In the pressure regulator control system, the opening of the discharge valve is enlarged and is vented into the atmosphere by the pressure regulator so that the compressor continues to operate with reduced drive power and generates less heat during the no-load condition. In the pressure control system, the pressure discharge valve as well as the suction valve are opened during the no-load condition.

Abstract: PURPOSE:To perform the highly accurate and speedy sorting operation of the title memory device on the basis of information on a wafer by a method wherein stored information is output from a sense amplifier only when stored information on a memory cell is read out within the readout reference time based on a reference clock. CONSTITUTION:When an address signal is input to a terminal 11, corresponding stored information '1' inside a memory cell array 14 is output via an address circuit 12 and an address decoder 13. The stored information is sent to a sense amplification circuit 15; it is output after a prescribed delay time TS. On the other hand, the circuit 15 is changed from ON to OFF so as to be delayed by a prescribed time TC1 from the output timing of the address signal by means of a control circuit 18 on the basis of a reference clock from a test input terminal 16. Consequently, when TS<TC1, '1' from the circuit 15 is output from an output data latch circuit 19, and '0' is output when TS>=TC1. Thereby, when an output value is '1', the title memory device is judged to be good, and, when it is '0', the title memory device is judged to be defective. The title memory device can be sorted speedily.
