Title: Hydraulic flow controller
Inventor: ARAKI HIDEO
IPC: F15B11/05
Filed: 1988-06-10
Abstract: PURPOSE:To simplify the structure of a hydraulic flow controller, so as to reduce its cost by comprising the hydraulic flow controller of a pressure detector for detecting the maximum value of applied pressure, a by-pass valve, a pressure generator, and a hydraulic cylinder device for operating a pressure compensating valve. CONSTITUTION:Between a pump 10 and actuator devices 200, 300, a pressure detector 28 for detecting the maximum value of applied pressure, a by-pass valve 32, a pressure generator 34 set on a by-pass line 30, a hydraulic cylinder device 36 for decreasing the throttle opening of a pressure compensating valve 24 when the pump control pressure of the by-pass line 30 becomes under predetermined No.2 flow control pressure so as to set a total flow rate which passes through a variable throttle 22 under the maximum discharge flow rate of the pump 10 are provided. Consequently, since a detector, a computation means and a compensation means do not have to be provided for each actuator, the whole structure of the hydraulic flow controller concerned can be simplified and its cost can be reduced.

Title: Printing device in slip printer
Inventor: KODAMA NAGAHIRO
IPC: B41J13/00
Filed: 1992-05-08
Abstract: PURPOSE:To prevent a blank printing of a printing head regardless of a slip size and a slip insertion position. CONSTITUTION:In a figure which is a plan view of a main part of a printing mechanism, numerals 23 are rollers for feeding forward a slip inserted in a direction shown by an arrow A, and a numeral 25 is a printing head reciprocating within a printing range. When a first paper detection sensor 27 detects paper, the rollers 23 are started. When a second paper detection sensor 28 detects the paper, the aforesaid printing head 25 starts printing. The sensors 27, 28 are disposed across a printing position on different end parts with respect to the printing limit. Therefore, if the slip inserted in the direction A is undersized or the insertion position of the slip is deviated to one side, at least one of the sensors 27, 28 is not turned on, and a printing action is not started. In this manner, the printing head can be prevented from conducting a blank printing.

Abstract: PURPOSE: To improve the S/N ration and distorsion characteristics of reproduced brightness signals so that the dispersion in the characteristics among rotary heads may not exert influences upon the brightness signals by shifting the phase of the carrier wave suppression amplitude-modulated signals to be produced or the reference signals of synchronous detection with respect to a reproducing head.  
     CONSTITUTION: Upon reproduction, residual side band signals Y c  are alternately reproduced for each fiel period from a track 5 by means of heads 2A and 2B and are fed through reproducing amplifiers 21A and 21B to a switching circuit 22. This circuit 22 is supplied as control signals with square wave signals, which are inverted for each half rotation of the heads 2A and 2B, and the signals Y c  are continuously taken out and fed to a frequency converter 23 so that the signals Y c  are converted into the residual side band signals Y v  of the carrier frequency f m . Since, moreover, the converter 23 is supplied from a converter 66 with the signals which have the same phase fluctuating components as the signals Y c  from the switching circuit Y c , the signals Y v  from the converter 23 contain no phase fluctuating component resulting from the phase fluctuations in the rotations of the heads 2A and 2B.

Abstract: PURPOSE:To enable the sealing of jet nozzles and the refilling with ink due to the suction of ink without causing trouble by providing the elongated track- shape rubber cap member capping the jet nozzles and reducing the thicknesses of both end parts of the outer periphery of the cap member. CONSTITUTION:The emitting orifices of jet nozzles 13 have a fine circular shape with a diameter of 0.04mm and are obliquely arranged in order to realize high printing density to realize a pitch (1/360 inch) between the nozzles in a longitudinal direction. The surface of the cap coming into close contact with the surface 12 of the head having this head structure has an elongated track shape in order to cover the outer periphery of the jet nozzles 13. In this shape, the rubber wall thickness of each of both circular arc end parts 3b is made smaller than that of each of the straight parts 3a by about 10-30% and the rubber deformation of the straight parts 3a and the circular arc parts 3b is made large in a sealing part to absorb an uneven shape due to the steep curvature in the circular arc parts. As a result, the close contact of the cap with the head surface 12 can be ensured without increasing spring load.
