Title: Management and control system for translation lookaside buffer
Inventor: SAKAMOTO YOSHINORI
IPC: G06F12/12
Filed: 1986-11-11
Abstract: PURPOSE:To ensure information on a TLB in some program environment against being affected by actions in other program environments by saving information on a buffer when each program is put on standby and restoring the saved information in the buffer when the control is again received. CONSTITUTION:Each program running in a CPU 1 is provided with an area 21 saving information on the Translation Lookaside Buffer (TLB) for address conversion. When each program is put on standby, the TLB information regarding the program is saved. When the control is again received, the saved contents are reset to the TLB. Thus such disadvantages are eliminated that the TLB information in one program environment is affected by actions in other program environments and performance substantially fluctuates due to situations in operation.

Abstract: PURPOSE:To bring an optimum state of drive by keeping the ratio of the output currents of a driving element to the output currents of a switching element constant at all times with respect to the fluctuation of the primary-side input voltage of a transformer having an element driving the switching element. CONSTITUTION:When a switch 3 is turned ON, DC voltage V1 is applied to the base of a drive transistor Tr25a through a resistor 25h, a switch Tr12 is turned ON, and a transformer 7 is energized. When supply voltage is increased and voltage V1 is also elevated, a Tr25f for regulating currents is operated in the direction that the base currents of the drive Tr25a fed from a winding 7b through a diode 21 and a resistor 25b are reduced, and the base currents IB of the switching Tr12 are also lowered, and brought to a value corresponding to the decrease of collector currents Icp. When supply voltage is lowered, the collector currents of the Tr25f are diminished, but the base currents of the Tr25a are augmented, and the base currents IB of the Tr12 are increased. Accordingly, overdrive is avoided at all times, and a circuit is protected.

Title: Pll circuit
Inventor: NACHI SHIKIKO
IPC: H03L7/08
Filed: 1994-11-01
Abstract: PURPOSE: To specify the range of use in the frequency converting characteristics of a voltage controlled oscillator(VCO) by adding a frequency limiting circuit for limiting the frequency range of an oscillated signal oscillated by the VCO to the PLL circuit. CONSTITUTION: Difference signals D and U outputted from a digital phase comparator based on the compared result are respectively inputted to a NOR gate 26 and an inverter 27 of a charge pump circuit 18, and the switch operations of 1st-5th switch elements 21-25 are controlled. Thus, when the difference signal D is inputted, a voltage to specify the upper limit of the use range of the frequency converting characteristics of the VCO is outputted and when the difference signal U is inputted, a voltage to specify the lower limit of the frequency characteristics of the VCO is outputted so that the range of use in the frequency converting characteristics of the VCO can be specified. Thus, when using a control clock signal for the character display position of an OSD, for example, no jitter is generated since the part of a too much high frequency converting gain is not used.

Abstract: PURPOSE:To simultaneously reduce both gate length and gate resistance, by a method wherein the boundary between a semiconductor active layer and an insulating layer is positioned in an aperture of photo resist subjected to gate-patterning. CONSTITUTION:On a semiconductor active layer 2, an insulating layer 8 whose etching rate is different from that of the layer 2 is formed. A photo resist 9 is patterned, which is used as a mask, and the layer 8 is etched. Source.drain electrode metal 30 is stuck on the whole surface by a vacuum evaporation method or the like, and the insulating layer 8 is left between a source and a drain by a lift-off method. After photo resist 10 is patterned, the insulating film 8 is etched by using the photo resist 10 as a mask, and the photo resist 10 is eliminated. Thereby a part where the semiconductor active layer 2 is exposed and a part where the insulating layer 8 exists are formed between the source and the drain. Gate-patterning is performed by a photolithography technique. In this process, an aperture part of photo resist 5 is made to overlap with the end portion of the insulating layer 8, and the boundary between the semiconductor active layer 2 and the insulating layer 8 is positioned in the aperture.
