Title: Drawing coordinate system and scale setting method
Inventor: SEKI MAKI
IPC: G06F3/048
Filed: 1988-07-15
Abstract: PURPOSE:To set a scale and a drawing coordinate system with the same operation by comparing the distance between two points of the drawing coordinate system with the distance between two points of a tablet coordinate system to obtain a graphic scale and setting the drawing coordinate system on a drawing based on the scale and two known points. CONSTITUTION:The coordinate values, e.g., (xt1, yt1) and (xt2, yt2) are obtained in a tablet coordinate system where the coordinate value of a drawing coordinate system shows two points P1 and P2 on a known graphic. At the same time, the distance LT between said two points is calculated. Then the distance LF between two points of the drawing coordinate system is calculated from the coordinate values, e.g., (xf1, yf1) and (xf2, yf2) of the drawing coordinate system of the two key input points P1 and P2. Then the distance LF is compared with the distance LT for acquisition of a graphic scale S. A drawing coordinate system XD-YD is set on a drawing based on the scale S and those two known points P1 and P2. Thus both the drawing coordinate system and the scale can be set with the same operation.

Title: Production of magnetic bubble memory element
Inventor: WATANABE HIROMICHI
IPC: G11C11/14
Filed: 1988-07-14
Abstract: PURPOSE:To obtain a magnetic bubble memory element which can reduce troubles caused by Au plating by forming a flattening film which reduces the surface unevenness on a protective film for protecting a transfer path constituted of a soft magnetic substance by applying a resin to the protective film prior to the formation of an Au bump. CONSTITUTION:A flattening film 6 which reduces surface unevenness is formed on a protective film 43 for protecting a transfer path 2 constituted of a soft magnetic substance by performing spin coating of a resin to the surface of the film 43 to a thickness equivalent to that of the film 43 before forming an Au bump. Then a window 44 for Au bump is formed to a conductor pattern 3 through the films 6 and 43 and an insulating layer 42 and a plating base 51 for forming the Au bump is formed by vapor-depositing Au on the entire surface. Therefore, side faces of uneven parts and acute corner sections where the Au tends to remain can be eliminated and, at the same time, bitten parts of the corner sections, through which the plating liquid easily percolates, can be filled up with the resin. Thus various troubles caused by the Au plating at the time of forming the Au bump can be reduced.

Title: Method for controlling air-fuel ratio of internal combustion engine
Inventor: KATO AKIRA
IPC: F02D41/14
Filed: 1988-07-13
Abstract: PURPOSE:To minimize the shifting of feeding air-fuel ratio from a target value over the wide range of a load by setting at least one of a multiplying term and an adding term for determining a fundamental fuel feeding quantity in a plurality of numbers. CONSTITUTION:In an ECU 5, a fundamental fuel feeding quantity is determined by using a defined multiplying term and a defined adding term with respect to the load of an engine 1. Also, the fundamental fuel feeding quantity is corrected using a correction factor corresponding to the deviation between the output signal of the O2 sensor 15 of the engine 1 and a defined target air- fuel ratio. In this case, the learning control of the multiplying term and adding term is carried out only on one of the high load side or the low load side in accordance with the deviation of the actual air-fuel ratio from a target air-fuel ratio and an engine load at the time of the stable operating condition of the engine 1. Thereby, it will not take place that, e.g., the multiplying term and adding term for high load are learningly corrected by an air-fuel ratio deviation at the time of low load, enabling learning correction to be the optimum value in each load zone.

Title: Polishing device
Inventor: TAKAHASHI KAZUO
IPC: B24B37/07
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To make abrasive powder to be supplied evenly and sufficiently between a work and a polishing tool while the polishing tool polishes the surface to be polished of the work, by supplying the abrasive powder to the surface to be polishing while contacting states and non-contacting states are repetitively maintained between the polishing tool and work. SOLUTION: Abrasive powder (slurry) 23 is held in spaces F1 formed of a work (wafer) 10 and the recessed sections of a polishing tool (polishing pad) 11. The slurry gets in the parts where the projection sections on the polishing surface of the pad 11 substantially come into contact with the surface to be polished of the wafer 10. As the pad 11 is rotated, the slurry 23 near the center of rotation of the pad 11 between the wafer 10 and the pad 11 becomes rougher, and the slurry 23 near the outer periphery of the pad 11 becomes finer. Therefore, a slurry supplying means supplies the slurry 23 to the spaces F2 between the wafer 10 and the pad 11, while a reciprocatory moving means 19 moves the pad 11 upward. When the slurry 23 is supplied, the pad 11 is continuously rotated in the same manner as the initial state (a).

Title: Recording and reproducing device
Inventor: OCHI ATSUO
IPC: G11B20/02
Filed: 1989-07-07
Abstract: PURPOSE:To prevent picture quality deterioration such as line crawling or line flicker by quantizing only a video signal part not including a synchronizing signal at recording, recording the signal while two reference signals are inserted to a prescribed period of each channel and controlling the the gain of a correction circuit at the reproduction. CONSTITUTION:Only a video signal part except a synchronizing signal part of an input signal is quantized at recording and subject to time axis expansion and the result is split into two channels. A reference signal of a level V1 is added to the resulting signal. Moreover, a signal of a level V2 outputted from a reference signal generating circuit 2 is added by adders 30a, 30b. Video signal period detection circuits 15a, 16b detect the position of a reference signal at the reproduction and generate a signal whose DC voltage is -Vo for a period of the video signal. Thus, the DC voltage is lowered only for a period of the video signal and a level difference between channels in the reproducing signal is brought into a permissible limit or a detection limit or below. Thus, deterioration in the picture quality such as line crawling or line flicker is avoided.

IPC: H04N9/73
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To obtain an optimum result to all color picture tubes by compensating an actual power exponent γ of a color picture tube or a projection tube that differs from an assumed power exponent γ with a DC offset corresponding to a cut-off error and a drive offset corresponding to a gain error. SOLUTION: A measured signal voltage for a vertical frame blanking period is inserted to a drive signal with respect to a color picture tube 1 by using a measurement line generating circuit 25 in a video signal processor 2. A controller of the video processor 2 controls both an amplitude of a measured pulse and a DC voltage offset so as to allow reference cathode currents Ik1, Ik2 to be generated in the color picture tube 1. A control algorithm uses an operating parameter corresponding to a value where a prescribed mathematical relation is held among a cathode control voltage Vk, the cathode current Ik and the power exponent γ. Thus, a cut-off point and a gain are optimally controlled for all types of color picture tubes.
