Title: Direct current amplifier circuit
Inventor: NAKAYAMA KAZUAKI
IPC: H03F3/45
Filed: 1978-12-28
Abstract: PURPOSE: To keep the offset voltage at the zero level by feeding the fluctuation of the power voltage back to the base of the input after detection through the Zener diode.  
     CONSTITUTION: In the normal power circuit, the power voltage has fluctuation in the conditions under which the ratio becomes constant between the +B and -B power sources. Accordingly, the fluctuation factor is zero, and thus the offset voltage becomes constant to the fluctuation of the power voltage. However, in the actual case, the fixed offset voltage remains. In this connection, the voltage is extracted from the -B side of the power voltage and via Zener diode ZD in order to detect the fluctuation of the power voltage. In case the voltage fluctuation is detected, the voltage difference obtained by dividing Zener voltage VZ and the power source by resistances R 1  and R 3  is applied to the base of input transistor Q 1  in the direction where the offset voltage is negated.

Title: Optical disk device
Inventor: TSUYOSHI TOSHIAKI
IPC: G11B7/09
Filed: 1986-07-15
Abstract: PURPOSE:To secure the stable control properties of an optical disk device by substituting a sample error signal for the value obtained from the preceding sampled value for a single sampling period if it is decided that said error signal is not appropriate. CONSTITUTION:The signal DELTAX(t) supplied to a protecting circuit 11 is compared with the sampled value preceding by a step. The normal sampled value is confirmed when the difference obtained from said comparison is kept within a fixed range + or -DELTAw1. Then such a sampled value is available. While the wrongly sampled value is decided if said difference of comparison exceeds the range + or -DELTAw1, therefore the sampled value preceding by a step is used instead. A delay circuit 111 which delays the signal DELTAX(t) by a sampling time T is used together with a window comparator 112 having the width + or -DELTAw for comparison performed between the 1-step preceding sampled value and the present sampled value. A track holding circuit 113 holds an input only for a period during which the comparator 112 decides that the present sampled value is wrong and otherwise transmits the signal DELTAX(t) as it is. Thus it is possible to secure the stable control properties for an optical disk device despite a detection error of a servo signal.

Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To prolong the life of an electrode to be in contact with an injection needle and to stably perform a processing regardless of the diameter of the injection needle. SOLUTION: Roller-like electrodes 5 and 6 are rotated by a DC motor 2. Also, power is supplied through brushes 10a and 10b to the electrodes 5 and 6. When the tip of the injection needle N is brought into contact with a first roller-like electrode 5 and a part slightly on a root side from the tip part of the injection needle N is brought into contact with a second roller-like electrode 6, the part of the injection needle N held there between both electrodes 5 and 6 is melted by Joule heat. By pressing an injector so as to bring the injection needle N into contact with the electrodes 5 and 6 at all times, the large part of the injection needle N is melted. Since the first roller-like electrode 5 is in a tapered shape and the wide and narrow gaps of the electrodes 5 and 6 are formed, the part of the gap suitable for the diameter of the injection needle is used.  Thus, maintenance is facilitated.
