Title: Duty ratio correcting circuit
Inventor: OONO YOSHIHIRO
IPC: H03K5/08
Filed: 1984-05-31
Abstract: PURPOSE:To set optionally the duty ratio of a pulse signal whose duty ratio is not fixed by detecting the leading edge of an input pulse and generating a saw- tooth wave. CONSTITUTION:When the digital signal A whose duty ratio is not constant is supplied to a monostable multivibrator circuit 1, the leading edge of the input pulse is detected to obtain a pulse B. An operational amplifier 2 form an integration circuit together with C1 and a constant current is inputted through R2 to charge the C1. The C1 is discharged every time the pulse B is outputted, so the saw-tooth wave C appaears at the output terminal of the amplifier 2. The signal C is smoothed through R4 and C2 to obtain a mean voltage D. Then, the signals C and D are inputted to an analog comparator 3, which performs binary coding to obtain the digital signal which synchronizes with the input signal and has a 50% duty ratio. Further, the duty ratio is varied optionally by varying the ratio of the mean voltage D and saw-tooth voltage C.

Title: Element for detecting focus in optical pickup
Inventor: YOKOMORI KIYOSHI
IPC: G11B7/09
Filed: 1985-05-23
Abstract: PURPOSE:To eliminate the laboriousness in adjusting the position where a focus detecting element is disposed while the focus detection with high accuracy is possible by disposing said element approximately parallel with the optical axis of a luminous flux for focus detection. CONSTITUTION:The element 50 for detecting focus is constituted of a photodetector 52 and a prism array 54 and is used by being so disposed that the prism arranging direction is approximately parallel with the optical axis of the luminous flux for focus detection. The direction where the photodetecting face of the photodetector is arranged is in parallel with the prism arranging direction and therefore the direction where the photodetecting face is arranged is inevitably approximately parallel with the optical axis. A relatively large change in the optical axis direction of the luminous flux for focus detection is thereby detected and a focus detection signal is generated and therefore not so much high accuracy is required for adjusting the position where the element is disposed and the focus detection with the good accuracy is made possible.

Title: Secondary electron multiplier and photo-electron multiplier with same secondary electron multiplier incorporated
Inventor: KUSHIMA HIROYUKI
IPC: H01J43/20
Filed: 1989-04-28
Abstract: PURPOSE:To obtain an electron multiplier and a photo-electron multiplier which are highly efficient by correcting the orbits of secondary electrons emitted from dynodes in the first stage, enhancing a carry-over factor over to dynodes in the second stage, and thereby letting light decrease an electron running time difference to a great extent. CONSTITUTION:Potential between a net shaped electrode 61 in the first stage and a dynode 71, is made to be different roughly by -3V through -9V, an electron orbit t1 at the upper end 91 of an electrode element 9 is corrected, thereby disabling electron emission from the electrode 61 in the first stage. This therefore permits an electron running time difference T from an electron orbit t2 at the lower end 92 and an electron carry-over factor eta over to a dynode 72 in the second stage to be enhanced. This situation results in characteristics as shown by the figure wherein, for example, no change is made in the time difference T as far as the potential difference VC remains to be -0 to -2V, the time difference is gradually decreased when the potential difference is increased beyond -2V, it will be lowest when the potential difference is equal to -5V, and it will be hardly changed when the potential difference is equal to or more than -5V. On the other hand, a carry-over factor eta is moderately increased until the potential difference goes roughly up to -5V, and starts to be gradually decreased after the potential difference goes beyond said value. Namely, the most excellent characteristics are thereby exhibited when the potential difference VC is roughly equal to -5V.

Title: Ink jet recording apparatus
Inventor: SATOU KAZUHIKO
IPC: B41J2/01
Filed: 1984-05-30
Abstract: PURPOSE:To enable the detection of ink droplets exerting no effect upon a head even during the movement of said head, by providing a charge electrode for charging ink droplets and a detection electrode for detecting an induction current generated with the flight of the ink droplets while providing a shield electrode to the intermediate position between a nozzle and the detection electrode. CONSTITUTION:When voltage is applied between an ink jet head 21 and a charge electrode 25, conductive ink is formed into charged ink droplets 24 when injected from the leading end of a nozzle 23 while the ink droplets 24 pass between the charge electrode 25 and a shield electrode 27 to be flown toward a detection electrode 28. Charge having polarity opposite to the charge of the charged ink droplets 24 is induced in the detection electrode 28 and an induction current flows to generate potential difference between both terminals of a resistor 30. This voltage is amplified by an amplifier 31 and, when reaches reference voltage or more, a detection signal is detected. By this method, the presence or absence of the injection of ink droplets, that is, the presence or absence of the clogging of the nozzle is detected. Because the shield electrode 27 electrically shields the head 21 from the charge electrode 25, the induction current generated by the vibration or displacement of the head 21 is removed and, therefore, no noise generated by movement is detected.
