IPC: G11B7/13
Filed: 1987-04-10
Abstract: PURPOSE:To stably grasp a seeking direction and, at the same time, to constitute a highly reliable accessing circuit, by providing a means which holds readout signals and another means which adds the peak signal of the output of the first mentioned means to a signal indicating the total reflecting light quantity. CONSTITUTION:Readout signals 30 are inputted to a reproducing circuit 33 and peak holding circuit 34 after their voltages are transduced and amplified by means of a resistance 31 and amplifier 32. The peak holding circuit 34 outputs correct signals 35 which contain envelope waveforms to an adder 38 and, upon receiving the correct signals 35 and total reflecting light quantity signals 36 outputted from another adder 28, the adder 38 outputs new total reflecting light quantity signals 39 having no influences of pits. Therefore, dropped quantities of the total reflecting light quantity due to the presence of pits is corrected and the moving direction of an optical head can be detected accurately.

Title: Method and apparatus for deflecting arc pillar in arc welding
Inventor: ISHIWATARI KOUJI
IPC: B23K9/127
Filed: 1982-05-26
Abstract: PURPOSE:To optionally deflect a vertical arc pillar toward a groove wall, by assembling an electromagnet into a welding torch and controlling the polarity of the electromagnet by arranging both magnetic poles of the magnet pulled out from the magnet in such a way that they face to each other with a torch electrode in between. CONSTITUTION:For making arc welding, a magnetic oscillating head 19 is installed to a welding torch section 23. This head 19 is formed, for example, by winding magnetic coils 14 and 15 around an iron core 13 and magnetic poles 16 and 17 are extended downward from each pole of the iron core 13 and the magnetic poles 16 and 17 are arranged in such a way that they face to each other in the direction parallel to a groove line with the lower part of a torch electrode 33 in between. When a welding current is made to flow from a base material 22 to the electrode 33, an arc pillar 18 is directed to a location directly below the electrode 33 and falls in a molten pool 39. When a magnetic field is applied to the arc pillar 18 in the direction of forward-backward moving axis X (parallel to the groove line) by exciting the magnetic coils 14 and 15 under this condition, the arc pillar 18 is deflected toward a groove wall. Therefore, when the polarity of magnetic poles 16 and 17 is controlled, the arc pillar 18 can be deflected toward an optional groove wall.

Title: Charge transfer element
Inventor: HIRAMA MASAHIDE
IPC: H01L21/339
Filed: 1993-03-23
Abstract: PURPOSE:To prevent a difference from being generated between the charge and voltage conversion ratios of a plurality of charge and voltage conversion parts even if a matching deviation is generated between floating diffusions and masks for lead-out electrode formation by a method wherein the charge and voltage conversion parts of a plurality of charge-transfer parts are formed in such a way as to have patterns moved in parallel to each other. CONSTITUTION:In a charge transfer element, charge transfer parts 3e and 3q are not made axially symmetric to each other with a center line 7 as the center, but are formed in patterns moved in parallel to each other in the direction rectangular to the center line 7. Thereby, even if lead-out electrodes 6e and 6q are shifted on the side lower than a reference position to floating diffusions 5e and 5q, the opposed area of the electrode 6e to the diffusion 5e and the opposed area of the electrode 6q to the diffusion 5q are both smaller than a reference value. As a result, no difference is generated between the opposed areas.

Title: Print timing control system and ink jet recorder using same system
Inventor: FUJIMURA YOSHIHIKO
IPC: B41J2/01
Filed: 1990-04-04
Abstract: PURPOSE:To make it possible to form ink dots on a recording sheet with a predetermined pitch constantly by changing an output delay time of a print timing signal with respect to an input of a position detecting signal of a record head based on a predetermined relational expression with respect to a flying time of an ink drip and a scanning speed of the record head. CONSTITUTION:At operation means 6, a flying time Ti of an ink drip is operated to output. At output means 7, a data Tp loaded on a down counter 71 is immediately counted down. Then, the data being counted down is always compared with a data Ti to be outputted from the operation means 6 at a comparator 72. When the Tp coincides with the Ti, a print timing signal is outputted. Accordingly, assuming that the number of the count down is Td, an expression Td=Tp-Ti will be established. The ink drip flown in accordance with such a print timing signal is stuck on a recording sheet 2 at a position deviated by 1 print pitch from an output position of a position detecting signal at the time of the count down.

Title: Semiconductor optical element
Inventor: SUGAWARA MITSURU
IPC: H01L31/14
Filed: 1988-04-11
Abstract: PURPOSE:To obtain a uniform exciter absorption peak for enabling a high light absorption coefficient to be obtained by introducing a transition metal into a wall layer and a well layer, and providing a superlattice in which the carrier concentration is reduced. CONSTITUTION:When a transition metal forming an accepter level near about the center of the forbidden band width Eg is introduced into a wall layer A and a well layer B, the atoms of Fe take in the electrons in a superlattice before introducing the transition metal for ionizing them so that the carrier concentration of the superlattice is lowered. In this case, when the carrier concentration of Fe shall be NFe, and the carrier concentration of the superlattice shall be (n), lower concentration is generated under the condition (n)<NFe. Accordingly, Fe of NFe>1X10<16>cm<-3> is introduced into the superlattice, the carrier concentration of the superlattice can be made less than 1X10<14>cm<-3>. Thereby, a fixed electric field can be obtained regardless of the thickness direction of the superlattice so that a uniform exciter absorption peak and the high light absorption coefficient can be obtained.

Abstract: PURPOSE:To obtain the always optimum air-fuel ratio by correcting the output of an oxygen detecting means installed into an exhaust system on the basis of the exhaust temperature and controlling the flow rate of either the supplied fuel or the combustion air according to the corrected control signal. CONSTITUTION:The opening-degree of a flow-rate control valve 3 in a gas fuel conduit 2 is set through a control circuit 10 on the basis of the load information obtained according to the output of an electric-current detector 9 installed onto a generator 8 driven by an internal-combustion engine 1. At this time, the opening- degree is properly corrected through a correcting circuit 16 according to the output of an oxygen detecting element 14. Further, within the temperature range where exhaust gas is relatively low, correction is performed according to the output of a temperature detecting element 15, by adding a large value onto the output voltage of the oxygen detecting element 14 on the basis of the temperature characteristic value of the oxygen detecting element 14 provided for a RAM17 beforehand. Therefore, always optimum air-fuel ratio which is not influenced by the variation of temperature of exhaust gas can be obtained.
