Title: Method for refining organic compound for photographic photosensitive material
Inventor: TAKEDA AKIHIKO
IPC: G03C7/32
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To refine an organic compound for a photographic photosensitive material which does not adversely affect photographic performance through a simple operation at a high yield by using an ion exchanger as a solution of an organic compound for a photographic photosensitive material and an organic solvent. SOLUTION: Impurities contained in a crude product are removed by adsorption by bringing the crude product as a solution of an organic solvent into contact with an ion exchanger. That is, an organic compound for a crude photographic photosensitive material is used as an organic solvent and after removing the impurities, the ion exchanger is added to the solvent, so that the solvent is stirred into contact with the ion exchanger. Alternatively, the impurities are removed by a method by which the solvent is caused to pass through a layer filled with the ion exchanger. The treatment temperature is in the range of 20-100 deg.C, preferably in the range of 30-40 deg.C. The concentration of the solvent is in the range of 5-50 wt.%, preferably in the range of 10-30 wt.%. The throughput rate is preferably 0.5-2(liter/liter-ion exchange resin/hr).  After ion exchange treatment, the solvent is distilled off to obtain an organic compound for a refined photographic photosensitive material.

Abstract: PURPOSE:To improve efficiency and to reduce the dimension by providing a beam of the second elastic body to a free end of the cantilever of the elastic body, by sticking a piezoelectric body to one surface of the beam and by applying AC electric field there. CONSTITUTION:In an oscillator 30 of an ultrasonic linear motor the 1st cantilever 18 is constituted by sticking a piezoelectric body 17 to one surface of an electric body 16. An end of this cantilever 18 is fixed by a fixture 21 and to the other end an end of the 2nd cantilever 19 is secured to constitute the oscillator 30.

Abstract: PURPOSE:To reduce the number of components by applying control to a 3rd p-channel transistor(TR) connected to an output terminal and that of 5th and 6th n-channel TRs independently respectively, and using part of a signal used for controlling the p-channel TR for controlling the nchannel TRs. CONSTITUTION:With both a data signal 1 and a control signal 2 at high level, n-channel TRS 9, 10 are both turned on and a p-channel TR 4 is turned on. On the other hand, since n-channel TRS 7, 8 are both turned off, a p-channel TR 6 is turned on. Since an n-channel TR 11 is turned off, an output signal 3 goes to a high level. when the data signal 1 is at a low level and the control signal 2 is at a high level, the nchannel TR 7 is turned on and an output signal 3 at a low level is outputted from the output terminal. Thus, the high impedance state is obtained with a few components.

Abstract: PROBLEM TO BE SOLVED: To shorten a cooling period of time, and expand a contact area to transmit cold, and in addition, improve the cooling capability by providing a refrigerant gas valve which performs the putting in/taking out of a refrigerant gas based on a detected temperature of a temperature sensor. SOLUTION: When a temperature sensor 24 detects a temperature which is not more than a specified temperature being set in a control device 25, the control device 25 closes gate valves 15 and 16. By this motion, the feeding of a helium gas to a first stage cold head section F-1 is stopped. Then, the process is transferred to a motion temperature cooling stage wherein the cooling of a superconductive coil is performed by a second stage cold head section F-2 alone, and the superconductive coil 10 under an extremely low temperature state is obtained. At the time of a transfer to the motion temperature cooling stage, the helium gas may be discharged so that the gas may not remain in a cooling pipe 14.  Also, by totally closing the gate valves 15 and 16 under a closed state after the completion of a preliminary cooling stage, the cooling pipe 14 is prevented from being clogged with frost or ice due to the entering of moisture or the like in air.
