A compact tripod type constant velocity joint with double roller type roller units capable of preventing plastic deformation of snap rings in assembling. In each of the roller units, an outer roller has an inner diameter ‘Do’ of 26.4 mm or less. The inner diameter ‘Do’ (mm) of the outer roller, a groove depth ‘Depth’ (mm) of engaging grooves formed on the outer roller and an outer diameter ‘Ds’ (mm) of the snap rings satisfy the formula below. Then, in a state where the snap rings are seated in the engaging grooves, diametrical gaps of 0.1 mm or more are formed between outer peripheral ends of the snap rings and groove bottoms of the engaging groove. Do+2×Depth−Ds≧0.1.

摘要:
An optical disk driver using a top-loading mechanism is coupled to an operational processor, such as a personal computer. The term “a top-loading mechanism” means a mechanism for inserting and/or ejecting an optical disk via a top surface of the optical disk driver. Additionally, a display unit used for the operational processor can be located on an operational processing apparatus comprising such an optical disk driver and an operational processor. The optical disk driver includes a first case (12), accommodated in a housing (10a) having the operational processor therein, a second case (11); movable from a first position to a second position, the second case (11) projecting from the first case (12) so that an optical disk can be inserted and/or ejected via a top surface of the second case (11) when the second case being located at the first position, the second case being accommodated in the first case to be operatively connected to the operational processor when the second case (11) being located at the second position.
摘要:
A method of and an apparatus for recording an image. The method of recording an image while a plurality of long recording sheets are selectively being fed to a recording section, comprising the steps of specifying a desired one of the plurality of recording sheets; and locating the leading edge of the desired one at a ready state at a position which is downstream with respect to a recording position of the recording section in the direction in which the recording sheet is fed. The apparatus is arranged such that image recording is performed in accordance with image information while a recording sheet unwound from one of first and second sheet rolls is being fed to a recording section including a recording head. One of the first and second recording sheets is set to a predetermined position in the recording section, after recording onto the recording sheet is completed.

A disc drive is constructed from a main body which includes a mechanism unit having a disc rotating mechanism for rotating a disc and a play back mechanism for playing back information recorded on the disc, disc tray movably provided with respect to the main body for supporting a disc and a casing for housing the main body. The disc drive is provided with vibration absorbing members for suppressing transmission of vibration caused by high speed rotation of the disc from the main body to the casing. The vibration absorbing members are formed of elastical members and they are arranged between the side portions of the main body and the inside of the casing, thereby the main body is supported by the casing through the vibration absorbing members to prevent vibrations caused in the main body from being transmitted to the casing. Further, the casing has a U-shaped side plate and a top plate fixed to the side plate by screws, in which the top plate is in point contact with the side plate through a plurality of protrusions formed on upper edges of the side plate. This point contact between the top plate and the side plate makes it possible to prevent rattling from being caused by the transmitted vibrations, thereby preventing generation of noise.

The process for preparing anilines by reaction of phenols with an amination agent in accordance with the present invention is disclosed, which process is characterized by carrying out the reaction of phenols with an amination agent in the presence of a low alkali and weakly acidic alumina catalyst having the alkali oxide content of less than 0.5% by weight, said alumina catalyst being obtained by firing an alumina catalyst containing in a dry state more than 80% by weight of alumina and less than 20% by weight of silica at a temperature of 600.degree.-900.degree. C., followed by acid treatment. According to the present invention, there are obtained such excellent effects that even when the reaction is carried out at a temperature lower than those employed in the case of conventionally well-known catalysts, the desired anilines can be prepared in high yields and high selectivity and, moreover, a high catalyst activity can be maintained over a long period of time.The alumina catalyst used in the present invention is characterized by having the alkali metal oxide content of less than 0.5% by weight and pKa of from -3.0 to +6.8 as measured by Hammett's indicator, and containing in a dry state more than 80% by weight of alumina and less than 20% by weight of silica, and this catalyst is prepared by firing an alumina catalyst containing in a dry state more than 80% by weight of alumina and less than 20% by weight of silica at a temperature of 600.degree.-900.degree. C., followed by acid treatment.
摘要:
A process for preparing 2-unsubstituted imidazoles which comprises reacting an .alpha.-hydroxycarbonyl compound with a formamide in such amounts as to make the molar ratio of said formamide to said hydroxycarbonyl compound not more than 2 at a reaction temperature of 100.degree.-170.degree. C. in an atmosphere of ammonia gas. According to this process, 2-unsubstituted imidazoles may be obtained in very high yields. In addition, because no great excess of formamide is used in carrying out the reaction, an effect of not requiring the recovery operation incident to decomposition of formamide is obtained as well. And by removing formic acid formed as a by-product by the reaction, a reactor and separation equipment such as a distillation column are not corroded, and imidazoles of a high purity can be obtained.
摘要:
A recording apparatus adapted to accommodate first and second recording sheets rolled into rolls, selectively convey one of the first and second recording sheets to a recording section having a recording head, and record an image in accordance with image information on the selected recording sheet. The apparatus is capable of initializing the positions of the leading ends of the recording sheets in such a manner that they are positioned at a predetermined stand-by position. The apparatus may be adapted to display a message requesting the initialization after a cover over the recording sheets has been closed. Alternatively, the apparatus may have sensors for detecting the recording sheets and may be adapted to perform the initialization on the basis of the outputs of the sensors by cutting portions of the recording sheets at the leading ends thereof alternately. The apparatus may also have a register for storing data on a power supply turned-off condition, a cover-opening condition, or a condition in which a recording operation is stopped during recording, and may be adapted to perform the initialization when data on one of the conditions is stored at the start of a recording operation and erase the stored data after the initialization.
