Title: Method for operating control equipment of benzol group recovery apparatus
Inventor: NAKAMURA NOBUO
IPC: C10K1/16
Filed: 1987-08-28
Abstract: PURPOSE:To enable an efficient operation of a benzol group recovery apparatus by controlling a flow rate of absorbing oil of benzol based on a absorption factor of benzol group calculated from concentrations of benzol group in a crude yoke oven gas, a purified coke oven gas, a absorbing oil of benzol, a benzol containing absorbing oil, etc. CONSTITUTION:Concentrations of benzol group (BTX) 8, 9 in a crude coke oven gas (COG) G1 and a purified COG G2 are measured together with concentrations of BTX 10, 11 in a absorbing oil of benzol (DBO) and a benzol containing absorbing oil (BO). A theoretical equation on an absorption factor of BTX is obtained from these measured values. A rate 1 of DBO to a benzol absorption tower 20 is automatically controlled by using the aforementioned equation, so that a concentration of BTX in a purified COG comes to be a target value. On the other hand, BO is regenerated by desorbing the absorbed BTX in a benzol removal tower 30 after passing a BO heater 40, and the regenerated DBO is returned to the benzol absorption tower 20.

Filed: 1987-08-27
Abstract: PURPOSE:To permit the automatic discharge of air in a fuel feeding system by operating a fuel pump on the basis of the prescribed pump operation time so far as the closing of an ignition switch is at the first time after the connection of an electronic controller to an electric power source. CONSTITUTION:When an engine is in operation, if an ignition switch 6 is closed, and electronic controller 2 outputs an operation signal (d) for operating a fuel pump 5 for a little set time (e.g., 2sec) immediately after the closure of the switch 6. Further, when a driving signal (a) for a starter 7 is received, the operation signal (d) for the fuel pump 5 is outputted during the time of input of the driving signal (a). Further, when it is judged that the closing operation of the ignition switch 6 is carried out first after the connection of a battery 9, the fuel pump 5 is connected to the battery 9 through a relay during the pump operation time (e.g., 60sec) which is set for the discharge of air in a fuel feeding system 4, and the fuel pump 5 is operated.

Title: Regeneration of adsorbent for boron trichloride
Inventor: MURAYAMA TAKAHIRO
IPC: B01J20/20
Filed: 1983-11-15
Abstract: PURPOSE:To regenerate used active carbon and to recover simultaneously adsorbed BCl3 with almost same amt. of impurity as BC3 used in the starting stage by heating the active carbon in the first stage to recover gas consisting essentially of BCl3 and then heating said active carbon at higher specified temp. in the second stage to regenerate the active carbon. CONSTITUTION:For the regeneration of active carbon used for removal of Si compd., phosgen, and chlorinated hydrocarbons contained in BCl3 gas, the active carbon is first heated at 40-120 deg.C, and the gas consisting essentially of BCl3 eliminated from said active carbon is recovered, then the active carbon is heated at 200-700 deg.C. By this method, the active carbon is regenerated, and major portion of adsorbed BCl3 is recovered as BCl3 having almost same degree of the content of impurities as high as the BCl3 used in the starting stage. The regenerated active carbon is not deteriorated and is usable repeatedly. Therefore, the consumption of raw materials and adsorbent per unit weight of final product are remarkably reduced. The process contributes to cost reduction of purified BCl3.

Title: Explosion proof sealing plate for sealed battery
Inventor: INOUE HIROKI
IPC: H01M2/34
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To accurately set current shut-off pressure by making the size of a part formed in a recessed shape of an upper metal foil larger than the size of an opening of a spacer in the structure for cutting the electrical connection of upper and lower metal foils. SOLUTION: The size of an opening 8 of a spacer 5 is smaller than a recess. When the inner pressure of a battery reaches a given value set by the reversing pressure of an upper metal foil 1 and the breaking strength of an easily breakable part of a lower metal foil 2, the recess is reversed independent of a local shape change such as an R shape or a burr shape of the periphery part of the opening 8 of the spacer 5, the contact part with the lower metal foil 2 is pulled up, and part of the lower metal foil 2 is broken. The electrical contact between the upper and lower metal foils 1, 2 is broken to shut off current flow. Since the size for forming the upper metal foil 1 in a recessed form is made larger than the size of the opening 8 of the spacer 5, influence by the state of the opening 8 of the spacer 5 can be avoided.

Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To increase the operation clock frequency of a feedback equalizer. SOLUTION: Only when the decision result of a decision means 4 can be adopted before an arithmetic means 3 requires the output of a digital-analog converting means 7, in other words, before the necessary output of the decision means 4 is determined as to the operation of the decision feedback equalizer 1, digital feedback quantities are calculated by filter arithmetic units 5aA to 5bB in advance and converted by digital-analog conversion units 7a and 7b into analog feedback quantities. Then a selecting circuit 8 selects an analog feedback quantity according to the decision result of the decision means and supplies it to an arithmetic means. The filter operation and digital-analog conversion are made precedent to conventional operation timing, so the analog feedback quantity responding to the output of the decision means can be supplied immediately to an arithmetic means.

Abstract: PURPOSE:To adopt a real time type picture reading system by continuously baking a photoconductor material, low melting-point glass and a chloride under the conditions of the heat treatment of two kinds or more when low melting- point glass and the chloride are added to the photoconductor material and thermally treated. CONSTITUTION:CdSe powder, glass frit and a halide are added onto an insulating substrate 1 consisting of ceramics, glass, etc., and photoconductive paste 2 to which an organic solvent is added is applied in predetermined width. First activation heat treatment is conducted to the applied film 2, and a mixed gas in which the mixing ratio of oxygen to nitrogen is kept within a range of O2:N2=1:20-1:4 is made to flow at the rate of 1-10l/min.

Second heat treatment is performed in an inert gas, and an electrode 3 is formed onto the photoconductive film 2. Accordingly, particles are grown and crystallizability is improved under separate conditions, thus remarkably enhancing the characteristics of a photoelectric conversion film prepared by using powder, then promoting its stabilization.
