Abstract: A process for producing a hydrodesulfurization catalyst is disclosed, comprising impregnating an inorganic oxide carrier containing a crystalline aluminosilicate with a solution consisting of Group VI metal oxide, a Group VIII metal oxide, and phosphorus. Also disclosed is a process for deep hydrodesulfurization of a gas oil fraction using said catalyst to obtain gas oil having an extremely low sulfur content.

Abstract: A sliding type sunroof has a pair of rails, a front shoe slidably retained in each rail, and a sunroof panel supported by the front shoe and slidable together with the front shoe for opening the roof of an automobile. A lift down device for the sunroof includes a bracket pivotally connected to the front shoe at a pivot point and having the sunroof panel secured thereto, the sunroof panel being lifted down and placed in a slidable state by turning the bracket about the pivot point.

Abstract: A retractable lamp device for vehicles includes a vehicles includes a vehicle body having a space for accommodating a lamp, a cover member rotatably mounted on the body to open or close the space, a motor for rotating the cover member. The retractable lamp further includes a movable member connected to the motor and an adjusting member for adjusting the surface level of the vehicle body and the cover member from outside of the vehicle.

Abstract: Appearance of joints between partly overlapping picture signal segments from a plurality of solid-state image scanners can be effectively avoided by means of automatically phase-setting the scan start signals for the respective image scanners relative to each other so that the logical sum signal of the marker signals contained in the respective signal segments is minimized in width. The marker as a source of the marker signals is fixedly arranged on the original-copy supporting table or separately therefrom in the region of overlap of the scan ranges of adjacent image scanners.

Abstract: In a facsimile receiver, a reversible pulse motor feeds a continuous recording medium forwardly during recording, further forwardly to a cutter after the recording, and backwardly after cutting from the continuous recording medium by the cutter of a separate sheet on which a figure, namely, a picture or its equivalent, is recorded. During the recording, clock pulses may be counted by a counter and supplied in groups to the pulse motor to stepwise feed the recording medium. The amount of the further feed should not be less than that of the backward feed. Preferably, these amounts are determined by two counters energized when the recording ends and when the cutter works, respectively, to count the clock pulses to predetermined counts. Alternatively, a single counter is similarly energized to count the clock pulses to a predetermined count so as to render the amounts equal.

Abstract: In a facsimile receiver comprising a recording unit for forming a latent image on a continuous recording medium fed by a variable speed feed unit and a developing and fixing unit for processing the latent image into a visible one, a controllable feed unit and a store unit are arranged successively prior to the processing unit. When fed to the controllable feed unit by the variable speed feed unit, the continuous sheet is held by the former so as to heap in the store unit. Responsive to a page end signal, a cutter disposed prior to the store unit cuts the continuous sheet into a separate sheet and a remaining continuous sheet. The separate sheet is now fed by the controllable feed unit to the processing unit at a predetermined speed. The recording medium may be one of stacked separate sheets, when the controllable feed unit feeds the above-mentioned one separate sheet a predetermined interval after the separate sheet is fed thereto by the variable speed feed unit.

Abstract: A paper feeder comprising a roller-belt feeder unit for feeding sheets of paper or the like one by one from a stack thereof to a utilization device and further comprising an auxiliary belt in contact with the feed roller of the feeder unit on its upper half circumferential surface for pressing the leading edge of the lowermost sheet of paper down to the feed roller. The auxiliary belt is substantially parallel at the area of contact to the main belt comprised by the feeder unit to feed the superposed sheet back to the stack and forms at the area of contact with the lowermost sheet an acute angle smaller than another angle similarly formed by the main belt with the lowermost sheet. The coefficient of friction is the greatest for the roller and smallest for the auxiliary belt. The auxiliary belt may be kept still, passively driven by the roller, or positively driven either in the same or in the reversed sense as the main belt.

Abstract: A process for producing an infusible and insoluble granular sulfurized material by reacting a petroleum heavy material and sulfur with stirring in the presence of a reaction medium and further in the presence of, if necessary, an infusible and insoluble solid material, and, further, a process for producing granular carbon comprising carbonizing the granular sulfurized material produced above or alternatively a process for producing granular activated carbon comprising carbonizing and activating the granular sulfurized material.
