摘要:
A process for the preparation of peroxides by condensation reaction of a tertiary organic hydroperoxide with a tertiary alcohol, which is characterized in that zinc chloride is present as a catalyst in an amount of at least 1% by weight based on the tertiary alcohol, is disclosed. This process can be advantageously applied to continuous manufacture of peroxides, and according to this process, peroxides can be obtained in high yields.

A revocation list is registered a public ROM area. The revocation list designates at least one electronic device in which use of the storage medium by the designated electronic device is to be revoked. A controller receives from the electronic device which attempts to access, identification information indicative of the electronic device, and checks whether identification information corresponding to the received identification information is contained in the revocation list, thereby determining whether or not use of the storage medium by the electronic device which attempts to access should be revoked.
摘要:
A motor has its rotating shaft fixed by a fixing member so as to be inclined at an angle of θ to the horizontal direction. A supporting member is attached to the rotating shaft of the motor. A plurality of accommodating units are distributed at equal spacing along the circumference, centered on the rotating shaft of the motor, of the supporting member. A pair of peripheral surface members in each of the accommodating units is attached to the fixing member so as to be capable of freely opening and closing by a supporting shaft, and has an approximately square columnar shape in its closed state. An opening at one end of the pair of peripheral surface members having the approximately square columnar shape is opened, and a bottom surface member is arranged on an opening at the other end thereof. Each of the accommodating units is attached to the supporting member such that the supporting shaft is inclined at an angle of α to the rotating shaft of the motor.

摘要:
An improved electronic speaking document viewer is provided in order that a user can readily use electronic texts in the same manner as reading text images printed on paper. The electronic speaking document viewer accommodates a semiconductor storage card in the form of a detachable card type storage medium and includes a speech synthesis unit for performing speech synthesis on the basis of the intermediate language data stored in the semiconductor storage card, and a synthesized speech outputting unit for outputting the synthesized speech as synthesized by means of said speech synthesis unit. In accordance with the present embodiment, a high quality of synthesized speech is accomplished by the use of the intermediate language data S. The electronic speaking document viewer further comprises a text data display unit for displaying the text data consisting of letters in synchronism with the synthesized speech.
