Title: Speed detection system for recording and reproducing head
Inventor: TAKASAGO MASAHIRO
IPC: G11B21/08
Filed: 1991-08-01
Abstract: PURPOSE:To exactly detect a reliative head speed for a track at the time of seek by removing the influence of a track vibration based on the eccentricity of a disk. CONSTITUTION:At the time of a track follow-up control (the operation of each precise and rough servo system 15-16, and 17-20 by a switch 12 turning-ON), the currents of a voice coil motor 10 for driving an optical head 9 (which are in proportion to the acceleration of the optical head) is preliminarily detected by a current detecting circuit 21, and the detected data are stored in a memory 23. At the time of the seek (switch 30 turning-ON), the data of the memory 23 are added to the detected currents (indicating the acceleration of the head for a fixed part), and integrated by an integration circuit 33 in order to obtain the relative speed signal of the head for the track. Afterwards, the signal is added to a signal obtained by differentiating a track crossing signal 14 which is turned to a pulse by a differentiation circuit 32. An added output 39 is turned to the exact relative speed signal of the head in consideration of the track vibration, so that the exact speed control can be attained by comparing this signal with a target speed signal 40 by a comparator 38.

Title: Ink supply device for ink jet printer
Inventor: YAMAZAKI HIROSHI
IPC: B41J2/175
Filed: 1981-12-28
Abstract: PURPOSE:To cause an ink jet printer to perform printing operation immediately after resumption by the use of such an ink supply device wherein the generation of negative pressure at the nozzle side is prevented by causing the outlet of a discharge pipe to interconnect with ink in an ink tank at a position lower than the nozzle hole of a jet head. CONSTITUTION:When an exit 14 is caused to interconnect with a discharge outlet 13 by turning an electromagnetic valve 2 off (an entrance 12 is shut off from the exit 14), ink spouting instantaneously stops as the pressure inside an ink supply pipe 5 and a head 3 abruptly falls, but the outlet of a thin pipe 8 whose inner diameter is made small is applied with ink pressure, since it is opened into ink at the bottom of an ink tank 1. Consequently, the flow of ink into the ink tank 1 through an ink discharge pipe 7 is disturbed by fluidic resistance and such an abrupt change of pressure that may generate negative pressure in the nozzle of the head 3 is prevented.

Abstract: PURPOSE:To provide a tube surface display device capable of appropriate tube surface display in the TV receiver of a step scanning system by displaying tube surface display data for one horizontal line at a double speed twice on the same horizontal line. CONSTITUTION:In the TV receiver capable of sharing the video signals of an NTSC system and an HD system, input video signals are inputted to a video signal processing circuit 1 and a synchronizing separator circuit 2 respectively.
