摘要:
Digitally designed vertical synchronizing separator and framing circuit in association with a digital servo LSI for a video tape recorder are particularly designed to be noise-free system for a composite synchronizing signal reproduced from the video tape recorder and utilize a reference clock pulse with the synchronizing signal and a counter with a feed back of the contents of the counter to control the supply of said composite synchronizing signal.
摘要:
A novel circuit is provided for controlling an alternating current supplied to a load which includes a variable impedance element in the form of a low emitter concentration transistor which is bidirectional, and which has a high gain. The impedance of the variable impedance element to the flow of current therethrough is substantially the same in either direction of current flow.

Agri-horticultural pest control compositions having outstanding control effect on pests, in particular, agri-horticultural pests, which comprise as active ingredients one or more 4-(3-butynyl)aminopyrimidine derivatives represented by the general formula [I], namely, where R1 is typically selected from among: a) phenyl c) —SiR5R6R7 (R5, R6, and R7 which may be the same or different represent a linear or branched alkyl having 1-6 carbon atoms, a linear or branched haloalkyl having 1-3 carbon atoms which is substituted by one halogen atom, a linear or branched cyanoalkyl having 1-3 carbon atoms which is substituted by one cyano group, and phenyl); d) hydropgen atom; R2 typically represents a hydrogen atom; R3 typically represents a hydrogen atom; R4 represents a hydrogen atom and one or more agri-horticultural pest control compounds selected from among agri-horticultural antimicrobial compounds, say, multi-site contact active compouns, nucleic acids synthesis inhibitory active compounds, mitosis and cell divesion inhibitory active compounds, and/or agri-horticultural insecticidal, miticidal or nematicidal compounds, say, acetylcholinesterase inhibitors, GABA-gated chloride antagonists, and sodium channel modulators. Since the 4-(3-butynyl)aminopyrimidine derivatives and the existing antimicrobial active compounds and/or insecticidal active compounds are used in admixture, the 4-(3-butynyl)aminopyrimidine derivatives which are useful as pest control agents, particularly as agri-horticultural pest control agents, need be used in smaller amounts and yet their antimicrobial or insecticidal activity can be improved.

摘要:
In a word processor which includes a display unit, a keyboard unit and a printer, the display unit and the printer being viewable by an operator of the keyboard unit, a paper guide device which is detachably mountable on the printer to feed paper to be printed on into the paper inlet slot of the printer has a flat guide surface against which the paper to be printed on can be positioned and a draft holding member which is movable between a first position which allows paper which is placed against the flat guide surface to be supplied into the paper inlet slot and a second position wherein draft paper placed against the flat guide surface will be supported thereon for viewing by an operator of the keyboard unit.
摘要:
An artificial fur composed of a warp pile fabric comprising a ground construction and pile yarns fixed to the ground construction and present in the form of fiber bundles within the ground construction. The pile yarns are composed of guard hair fibers and under fur fibers, the constituent fibers in the pile portion being opened and raised and the guard hair fibers of the pile yarns having the top ends thereof tapered. Plural kinds of pile yarns differing in at least one of the fineness, color, thickness, and length of fiber are used and a stripe pattern is manifested on the pile surface by arranging the alignment and/or density of the pile yarns appropriately.
摘要:
Insert and assemble editing of video signals are carried out using a VTR having helically scanning rotary record/playback heads. Following the recording of a first video signal in slant tracks on the tape, the tape is stopped at an edit point where recording of a second video signal is to commence. Then the tape is run reversely while control signals associated with the locations of the tracks are reproduced. These control signals are counted and the tape is stopped when a predetermined number of such signals have been counted. Thereafter the tape is advanced to a noiseless-still-picture position, based on a counted number of oscillations associated with rotation of the tape capstan, at which an acceptably noise-free picture is obtained, notwithstanding that the head scan of the rotary heads does not completely coincide with the slant tracks when the tape is stopped. After this, the tape is run at normal speed, and when the tape reaches the edit point, the VTR begins to record the second signal, which is at that time in step with the previously-recorded first video signal.
