Filed: 1983-03-01
Abstract: PURPOSE:To enable to keep required characteristics of a fuel injection equipment for a long while, by correcting change in the effective stroke of a plunger caused by mechanical wear by detecting the fuel compression starting timing and the fuel injection terminating timing. CONSTITUTION:Simultaneously with sarting of pressurization of fuel through the turning and lifting action of a plunger 6, pressurized fuel is introduced into a chamber 34, and a pulse voltage is produced from a piezo-electric element 35 in response to the rapid pressure rise of fuel and applied to a control unit 25 as a first timing signal A1. The fuel injection terminating timing is impressed on a piezo-electric element 42 each time cut-off fuel is discharged to an annular chamber 18 and it is applied also to the control unit 25 as a second timing signal A2. The control unit 25 controls the injection quantity of fuel by producing a drive control signal D on the basis of the above two timing signals A1, A2 after making correction for the mechanical wear of an injection pump.

IPC: G09G3/20
Filed: 1988-02-15
Abstract: PURPOSE:To obtain a display screen of multi-gradation by a combination of different luminances even when a display plate which can execute only a binary display is used by varying a display luminance by a frame unit and forming one display screen by plural frames whose luminances are different. CONSTITUTION:When a vertical synchronizing signal VS is inputted, it is counted by a counter 22, and when its output is '1' (odd frame), a data selector 21 selects display data DA, and when said output is '0', said selector selects display data DB. The display data of one line portion which is selected passes through a shift register 23 and latched by a latching circuit 24. On the other hand, when the output of the counter 22 is synchronized with a horizontal scanning signal HS and provided to a blank signal generating circuit 33, the luminance of the whole display screen is varied by a frame unit, and by a screen of plural frames whose luminances and different, one display screen is formed. In such a way, even in case of a display plate for a binary display, a multi-gradation display can be executed by changing a combination of selected luminances at every display dot.

Filed: 1985-02-21
Abstract: PURPOSE:To control quickly and accurately the reading position of an information reading detector by using a mirror having the same refractive index and same thickness as a conventional disk in place of said disk. CONSTITUTION:A figure (a) shows a spot on the 4-split photodetectors PD1-PD4 when a mirror 2 is set at the focus position of an objective lens part 11 in a focus error detection mode. If the mirror 2 is shifted to the inside from the focus position of the part 11, the reflected light of the mirror 2 is applied to a PD 17 via a pritical angle prism 16 in the form of the diffusion light. In this case the spot on the detectors PD1-PD4 is shown in a figure (b). When the mirror 2 is shifted to the outside from the focus position of the part 11, the reflected light of the mirror 2 is applied to the PD 17 via the prism 16 in the form of the focused light. In this case the spot on the detectors PD1-PD4 is shown in a figure (c). Thus a focus error is detected by calculating (a+b)-(c+d), where (a-d) show the outputs of detectors PD1-PD4 respectively.
