Title: Mark detection system
Inventor: OZASA SUSUMU
IPC: G03F9/00
Filed: 1983-09-28
Abstract: PURPOSE:To enable to perform stable and high reliable mark detection by converging the substrate level of a mark detection signal to a fixed value always by a method wherein a switch to short-circuit an electric signal outputted from a detector is provided, and the switch thereof is opened after electron beam irradiation is started. CONSTITUTION:A capacitor 12 is arranged between the preamplifier 6 and the postamplifier 7 of a signal circuit to attain electrostatic capacity coupling, and moreover, the circuit is so constructed as to make action of a switch 13 connected to the output side of the above-mentioned capacitor 12 to be controlled by a mark position judging circuit 9. When irradiation of an electron beam is started at time Ts1 according to an electron beam irradiation signal (B), output (A) of a detector 5 is risen to a substrate level. The switch 13 is short-circuited at the point in time thereof, therefore input of the postamplifier 7 is zero. When the switch 13 is opened according to a switch control signal (C) at the point in time of time Ts2, the output signal of the detector 5 is inputted to the postamplifier 7 hereafter, while because the substrate level is substracted as the terminal voltage of the coupling capacitor 12, a signal waveform (D) at the condition wherein the substrate level is zero is generated to the postamplifier 7, and generation of detection error as usual is made to nil.

Title: Quantizing circuit
Inventor: FUKAYA NOBURO
IPC: G01R29/02
Filed: 1986-07-31
Abstract: PURPOSE:To enhance quantizing accuracy, by detecting the count noise of a clock pulse at the time of quantization and correcting a count value corresponding to said noise. CONSTITUTION:At first, an input wave form is made synchronous to a clock pulse by a synchronous circuit S. Next, the number of clock pulses synchronized by a counter CT are counted. Subsequently, the mutual phase difference between the phase of the front edge of the input wave form and the phase of the head pulse of the clock pulses synchronized and the mutual phase difference between the phase of the rear edge of the input wave form and the phase of the final pulse of the clock pulses synchronized are detected in phase difference detection circuits (AND2, NAND). Subsequently, both phase differences are analogously added up by holding circuits (C, Q3-Q6) and the calculated value is held. Further, from the view that the value held reaches a predetermined upper or lower limit value, the count value of the counter C is corrected by correction circuits (CP1, 2, AD) so as to be increased or decreased by the unit quantity thereof. By this method, a quantizing error can be reduced without especially increasing the speed of the counter CT or the peripheral elements thereof.

Abstract: PROBLEM TO BE SOLVED: To reduce the loss torque of a motor by controlling the hysteresis loss of the subject steel sheet per frequency in the case of being magnetized to the maximum magnetic flux density to the value equal to or below a specified one. SOLUTION: Steel, e.g. contg., by weight, 0.0020% C, 0.50% Si 0.25% Mn, 0.01% P, 0.20% Al and 0.0020% N is melted, is hot-rolled and is thereafter pickled. After that, this steel is cold-rolled and is subjected to finish annealing at 750 to 950 deg.C for 1 min in a 10% hydrogen - 90% nitrogen atmosphere. As a result, the hysteresis loss per Hz of frequency in the case of being magnetized to the maximum magnetic flux density of 1.5 T can be controlled to <=0.10 J/kg, and when an EPS motor is produced by using this steel sheet, the loss torque can remarkably be reduced. For obtaining this steel sheet, a common method may be used.  Namely, molten steel is subjected to degassing treatment to control its compsn. to the prescribed one, and this is successively subjected to casting, hot rolling and cold rolling to control its sheet thickness to a prescribed one, and after that, final annealing is controlled so as to regulate the hysteresis loss to a prescribed one.

Abstract: PURPOSE:To obtain images of high quality in the copy mode as well as the print mode by deflecting positively the overall electrification polarity of a toner to the side suitable for development in the print mode. CONSTITUTION:A bias voltage higher than that in the copy mode is applied to a developing roll 24 by a bias power source 30 to stick a toner 36 having a positive polarity to an exposed part, which has hardly an electric charge, without sticking the toner to an electrified part 32 on a photosensitive body 10, thereby performing reversal development.

Title: Dust-proof construction of damping mass
Inventor: MOTOYOSHI KUNIHIRO
IPC: G11B33/14
Filed: 1982-10-15
Abstract: PURPOSE:To improve the reliability of a disc device, by contacting both ends of an annular seal enclosing a contact piece respectively with a damping mass and an oscillator to prevent diffusion of dust generated from the damping mass system with less number of components without reducing the vibration proof effect of the damping mass. CONSTITUTION:The contact piece 13 having a cylindrical head is screwed to the damping mass 5. When the damping mass 5 is placed directly on a case 7, the contact area between the damping mass 5 and the case 7 correspond to the bottom area of the damping mass, but when the contact piece 13 is provided, the contact area is the bottom area of the contact piece 13, the contact area becomes smaller. Since both the ends of the seal 6 are contacted respectively with the damping mass 5 and the case 7, a closed space 20 is formed. The wear particle produced by vibrating friction is generated only from the contact surface between the contact piece 13 and the case 7 and not generated from other parts, then the said contact surface is enclosed with the seal 6 to form the closed space 20. Thus, the wear particle is enclosed in the space 20 to prevent diffusion of the powder.
