Title: Purification of hydrocarbon gas containing h2s and co2
Inventor: WATANABE KATSUROU
IPC: B01D53/52
Filed: 1978-12-15
Abstract: PURPOSE: To recover a high-purity and useful alkali hydrosulfide in the first step, and CO 2  and an alkali carbonate in the second step, by desulfurization and decarbonating washing of the title gas in the steps in order, respectively.  
     CONSTITUTION: A hydrocarbon gas containing H 2 S and CO 2  is washed with an agent consisting mainly of an alkali sulfide and/or hydrosulfide with an available alkali content of 30W80g/l and desulfurized, in the first step. In the second step, the gas is washed with water or a solution of an amine, or caustic alkali or alkali carbonate, and decarbonated. The separate removal of the H 2 S and CO 2  permits the recovery of impurities as useful carbonates, and CO 2 , and eliminates the cost of secondary pollution prevention.

Abstract: PURPOSE:To make it possible to control the stop, start and the like of oscillation caused by the change in film potential by light without contact by adsorbing the mixture of both or either of lipid and a material similar to the lipid and a long-chain carboxymethylene azobenzene expressed by the formula into a supporting body having micro pores. CONSTITUTION:The mixture comprising the following materials is impregnated in a supporting body having micro pores: both or either of lipid and a material similar to the lipid; and long-chain carboxymethylene azobenzene expressed by the formula. In the structure of the long-chain carboxymethylene azobenzene shown by the formula, a long-chain alkyl group is bonded to one end of an azobenzene skelton, and a carboxymethylene group is bonded to the other end. Therefore, the same attribute as the azobenzene is shown for ultraviolet rays and visible light. When the ultraviolet rays are projected on the mixture, the azobenzene becomes the bulky structure. Therefore, the interval between the aligned molecules is expanded, penetration through the micro pores is blocked and the oscillation can be controlled.

Title: Slide controlling device for vehicular sliding door
Inventor: KIKUCHI TAIZO
IPC: B60J5/06
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To perform the work of insetting detection without entailing any excessive load in constant speed control. SOLUTION: This device sets a period TL in time of low load, a period TH in time of high load, a low load duty dmin and a high load duty dmax making the specified constant speed achievable in each load in using a constant speed period Ta corresponding to a constant speed, and a standard duty da corresponding to any load in a horizontal stoppage as criteria, and thereby an interval between both high and low loads is regarded as being linearly varied, finding a duty (d) for performing constant speed control considered with the load by the stoppage (an inclined state to the traveling direction), and the motor duty control afterward the measured interval is carried out with the duty (d).  Since sliding operations can be done at the specified constant speed with suitable driving force at all times, such a problem that undue load is uselessly produced in control of judging insettingness by a variation in speeds is thus preventable.
