Abstract: Seek operation of a seek control section is monitored by an error monitoring section, and when a seek operation does not end normally, the control is forcedly switched over to fine control by the on-track control section without reporting the error to the higher-level controller. The error monitoring section variably sets a seek timeout time Ts depending on the seek distance between the current position of the head and the target position at the start of seek, for example. When the seek timeout time Ts elapses before the target position is reached, it is judged as an error.

Abstract: A camera which imprints alphanumeric messages on the film. The camera allows a user to view, in the order of most frequently used, the messages which can be imprinted. In order to reduce the cost of the camera, there is a dot matrix LCD display which can only display a limited number of characters which is less than the total number of characters of the largest message. After a user takes a picture, the dot matrix display scrolls through the message which has been imprinted on the film so that the user can confirm that the correct message has been imprinted. The speed at which the characters are scrolled or displayed is determined based on the total number of characters of the message. As an alternative to scrolling, the characters can be displayed one or two at a time. As an alternative, instead of displaying the alpha-numerical characters of the message, a graphical indication is given that some type of information has been imprinted on the film.

Abstract: Clad pipe having an inner pipe and an outer pipe metallurgically bonded to each other is manufactured by a process comprising the steps of: (a) preparing an inner pipe and an outer pipe made of different metallic materials, the outer pipe having an inner diameter larger than the outer diameter of the inner pipe; (b) forming an Ni-B layer by electroplating or electroless plating on the surface of one of the pipes facing the other pipe when the two pipes are assembled, the Ni-B layer having a thickness of 2-100 .mu.m and consisting essentially, on a weight basis, of B: 0.5%-7%, Fe: 0%-30%, P: 0%-7%, and a balance of Ni and inevitable impurities; (c) assembling the two pipes by inserting the inner pipe into the outer pipe; (d) subjecting the assembled pipes to cold working for reduction in diameter to such a degree that the outer diameter of the inner pipe is reduced by from 0.

Abstract: The present invention provides a bicyclolactam derivative which has the following formula and is useful as medicaments for treating senile dementia, i.e., as cerebral function improving agents and cerebral metabolism activators or anoxic brain damage protectives ##STR1## wherein R is benzoyl group which may be substituted with halogen atom, lower alkyl group, lower alkoxyl group, nitro group, cyano group or amino group; l is 1 or 2; m is 0 or 1; and n is 0, 1 or 2, provided that m and n are not 0 at the same time.

Abstract: An extrusion molding method for improving the fluidity of a molding material in the die and significantly improving the productivity of the molded article of uniform thickness, and an extrusion molding apparatus adapted for smoothly carrying out the method and having an unsophisticated constructional arrangement, are disclosed.Molding is carried out while the die to which an extrusion orifice gap adjustment device is annexed is kept in resonant vibrations. The extrusion orifice gap adjustment device is annexed to a portion of the die constituting an extrusion orifice section, and molding is carried out while only the portion of the die is kept in resonant vibrations. The extrusion orifice gap adjustment device is annexed at a node of the resonant vibrations.

Abstract: Disclosed is a plasticization method in which a molding material is supplied to a cylinder having a built-in screw to plasticize the molding material, and further, at least one of the cylinder and the screw is resonated to carry out the plasticization of the molding material. Also disclosed is a plasticization method in which the cylinder is vibrated by progressive waves to plasticize the molding material, and an apparatus able to carry out these plasticization methods.

Abstract: An improved method for carrying out an extrusion is provided, wherein an extrusion material in a flowable state is passed through a die under a pressure to impart a desired shape thereto, and the extrusion is carried out while the die is resonated by an ultrasonic wave in such a manner that the resonance occurs at an n wavelength, wherein n is m/2 and m is a positive integer. Further, an apparatus suitable for carrying out this extrusion method is provided.
