Title: Ring oscillator type voltage controlled oscillator
Inventor: IWAMOTO YOSHIHIRO
IPC: H03L7/099
Filed: 1992-01-10
Abstract: PURPOSE:To attain the oscillation even when a control voltage is decreased by connecting an N-channel transistor(TR) in parallel between a drain and a source of the N-channel TR in an inverting circuit and biasing a gate terminal to a high potential. CONSTITUTION:An N-channel transistor(TR) N3 is connected in parallel between a source and a drain of an N-channel TR N1 in an inverting circuit controlled by a control voltage Vc. Then a gate terminal VB is set to a higher potential (e.g. to VDD) with respect to a source VSS. Since the TR N3 is always turned on in this inverting circuit, the circuit acts like a circuit having a propagation delay time by TRs P1, P2, N2, N3 independently of the quantity of the control voltage Vc of the TR N1. Thus, even when the control voltage Vc is lower, the inverting circuit of multi-stage configuration uses the TRs P1, P2 to implement charging and uses the TRs N1, N2 to implement discharging and the oscillation at a low frequency is attained.

Abstract: PROBLEM TO BE SOLVED: To enable clipping processing with a little storage capacity by converting the bit map data of (n) gradation (n>1) to the bit map data of (m) gradation (m>n) including the gradation expressing a form based on form data. SOLUTION: When font data or graphic data are supplied to a data input part 12, image data are supplied through respective elements 14, 15 and 16 or the like to a clip converting part 20. When a rectangular clip area is set in the clip converting part 20, the circumscribed rectangle of an image related to the image data is calculated and when the side of the rectangular clip area crosses the circumscribed rectangle, the clipping processing of free form to multilevel bit map data is executed so that the pixel corresponding to the part outside the clip area is changed to the gradation showing 'transmission'.

IPC: C21C7/10
Filed: 1993-01-13
Abstract: PURPOSE:To reduce the reaction with nitrogen in the air by starting bubbling after reaching a specific value of the vacuum degree. CONSTITUTION:An Ar gas supplying pipe 5 is set at the bottom part in a ladle 1 in a lower vessel 4 and the gas supply is started/stopped with a valve 8. The lower vessel is closed with an upper vessel 3 through a packing 6, and after reducing the vacuum degree in the vessel to <=100Torr, the valve 8 is opened and the Ar gas is bubbled into the molten steel 2. At the time of returning back to the atmospheric pressure in the vacuum vessel after completing the treatment, the valve 8 is opened and the pressure is returned back in the condition of no bubbling. Then gas containing no N2, e.g. Ar, CO2, etc., is introduced and the pressure may be returned back to the atmospheric pressure. By this method, when the reaction treatment in the molten steel is active as the N is not brought into contact with the molten steel, the good quality low nitrogen steel can be produced.
