    摘要: A process for producing isobutylene and methanol comprising: a first step of subjecting methyl-tert-butyl ether to decomposition in the presence of a catalyst to obtain a reaction liquid; a second step of washing the resultant with water to separate the reaction liquid into an oil layer and an aqueous layer; a third step of subjecting the oil layer to distillation to obtain a fraction containing isobutylene and a dialkyl ether from the top of a distillation column, a fraction containing methyl-tert-butyl ether and the heavy components from the bottom of the column and a fraction containing methyl-tert-butyl ether from a side cut of the column, and recycling the side cut fraction to the first step; and a fourth step of subjecting the aqueous layer to distillation to obtain a fraction containing methanol from the top of a distillation column and a fraction containing water from the bottom of the column.

    摘要: A display device is constituted by a pair of substrates at least one of which is provided with a display electrode. The display electrode comprises an electroconductive transparent film comprising indium oxide and/or tin oxide and having a surface unevenness of at most 30 Å. The transparent film may preferably be an ITO film containing an amorphous component. The transparent film is effective in improving a surface flatness allowing a good alignment control performance while retaining a good transmittance and a low sheet resistance and is readily etched with weak acid to suppress peeling of an underlying layer thereof and an occurrence of microcracks therein.

    摘要: Recording pulses are each provided in a train of divided pulses, one of which has a greater pulse width than the other divided pulse. Laser light power emitted by a laser diode is detected at predetermined timing corresponding to the greater-width divided pulse, and an electric current for driving the laser diode is controlled in such a manner that the detected laser light power appropriately follows a predetermined laser power value. Thus, in the case where the recording pulses are each provided in a train of divided pulses, this arrangement can accurately detect the laser light power and thereby achieves high-precision control of the laser light power.

    摘要: Means are provided for effectively restricting or preventing occurrence of abnormal noise under cold ambient. The means are durable, cost effective and also keep the function of a pulley. A ball bearing 2 of a single row type includes an outer ring 2a and balls 2c. The outer ring 2a and each ball 2c are contacted with each other at two points. An oil groove 5 is formed at a position adjacent to the contact positions P and Q on the raceway surface between the raceway surface 3a of the outer ring and the balls 2c. The ball bearing 2 is fitted within or made integral with the inner diameter of a pulley body 1 having a peripheral surface 1e to be contacted with a belt.

    摘要: A plug-jack connecting structure is provided which includes a jack having a sleeve at a forward end of the jack. The sleeve has a non-circular outside shape and has grooves cut in an outer periphery thereof. A plug has a ring rotatably mounted thereon at one end thereof for receiving the sleeve. The ring has a sleeve receiving hole which has a shape complementary to the outside shape of the sleeve. By turning the ring through a 90 degree angle into engagement with the grooves, the jack and the plug are connected in a state in which they are prevented from being disengaged.
