Title: Reduction of coke generation in carbon black producing furnace
Inventor: SHINOHARA KAZUAKI
IPC: C01B31/04
Filed: 1988-01-20
Abstract: PURPOSE:To reduce coke generation in a reaction furnace for producing furnace black and to improve the quality and productivity of the furnace black by providing projected parts and recessed parts to an inside wall of a reaction chamber zone of the furnace. CONSTITUTION:Many projections 1 are provided to the inside wall of a reaction chamber 2 of a reaction furnace for producing furnace black. Fuel oil is burnt in a combustion chamber 3 together with excess air. Hydrocarbon fuel oil 4 is injected into the combustion gas at high temp., and furnace black is produced by decomposing the fuel oil thermally in the reaction chamber 2. Due to the effect of many projections 1 formed on the inside wall of the reaction chamber 2, the amt. of coke deposited to the inside wall of the reaction chamber 2 is reduced without changing the amt. of the hydrocarbon feed oil to be injected, the amt. and proportion of air to be introduced, and without changing the quality of the carbon black from a fixed level.

Title: 1-2 shift valve in automatic speed changer
Inventor: SUMIYA KOUJI
IPC: F16H61/02
Filed: 1981-01-22
Abstract: PURPOSE:To separately set a speed change point respectively in operation of upshift and downshift, by such constitution that throttle and detent pressures are applied to separate pressure receiving surfaces. CONSTITUTION:When a shift lever is placed in a position D, there are guided governor pressure to a port 142r and throttle pressure to a port 142k respectively. If car speed is increased, the governor pressure overcomes the throttle pressure to set a spool 142 to an upper position and obtain the second speed shift state. At this time, the port 142k supplied with the throttle pressure is shut off by the spool 142, while a port 142h supplied with the detent pressure is communicated to a port 142i. In consequence, if an accelerator pedal is strongly depressed, the detent pressure is applied to a land 142a through the port 142i to set the spool 142 to the lower position and perform kick down operation to the first speed shift state.

Abstract: PURPOSE:To ionize a discharge space uniformly for obtaining a stable laser output without exciting laser gas, by providing vacuum gaps as preionizing gaps so that the laser gas is preionized by X-rays produced therein. CONSTITUTION:A plurality of principal discharging capacitors C2 are connected on both sides between an anode 1 and a cathode 2. Vacuum gaps 3a-3e are also provided.

The X-rays preionize the laser gas present in the discharge space between the anode 1 and the cathode 2. When the charging voltage of the principal discharging capacitors C2 reaches a self-destroying voltage of the anode 1 and the cathode 2, electric discharge is started between the electrodes to excite the laser gas. Thus, a laser output 6 can be obtained.

Abstract: PURPOSE:To treat a body to be treated uniformly, and to reduce the consumption of a treating liquid by installing a temperature control mechanism controlling the temperature of a cup at a fixed temperature to the first cup. CONSTITUTION:Temperature control mechanisms such as channels 9 flowing and guiding temperature-controlled water controlled at a fixed temperature are formed into an inner cup 4 such as a section just under a chuck ring 6.
