Patent JP-H11204544-A (JP)
Title: Compound semiconductor field-effect transistor and manufacture thereof
Inventor: KASAI NOBUYUKI
IPC: H01L29/812
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To shorten effective gate length, without performing the shortening of a gate-electrode length and to improve mutual conductance by cutting off a channel region in the depletion layer extending into the channel region from the gate electrode only in the channel region at the side of a source from the center. SOLUTION: The impurity concentration of a channel region 3a at the lower part of a gate electrode 6 is lower than that in the region on the side of a drain electrode 8 in a region 30 on the side of a source electrode 7 from the approximate center of the channel region 3a. In this structure, the extension of the depletion layer from the gate electrode 6 becomes larger than the region on the side of the drain electrode 8 in the region 30 on the side of the source electrode 7. As a result, when a negative voltage is applied on the gate electrode 6, the channel region 30 is pinched off in the region 30 on the side of the source electrode 7. In this case, since the shortening of the effective gate length which determines the pinch-off voltage becomes possible, the increase in drain voltage and the improvement of the mutual conductance can be achieved.

Title: Laser recorder
Inventor: SUZUKI KAZUHIRO
IPC: G02B26/10
Filed: 1987-01-16
Abstract: PURPOSE:To surely correct jitter by calculating the deviation between a detected scan period and a reference scan period and variably controlling the period of a clock signal in accordance with this deviation. CONSTITUTION:When a signal short pulse SOS is inputted to a jitter correcting circuit 9, the circuit 9 detects the period from the single shot pulse SOS of the preceding scan period to the current single shot pulse SOS and obtains the deviation between the detected value of the period and the reference value of the scan period and supplies a voltage signal corresponding to this deviation as the control voltage of a voltage controlled variable frequency oscillator (VCO) 10. Though the VCO 10 generates the clock signal whose period corresponds to 1/4-1/8 of one picture element of a recording picture, the period of the clock signal generated till then is corrected by the correction width indicated by said voltage signal and the clock signal is outputted if the voltage signal related to the deviation of the scan period is inputted from the jitter correcting circuit 9. The scan period of the laser light is detected and the oscillation frequency of clock pulses to synchronize the picture signal is variably controlled in accordance with the deviation between the detected value and the reference value, thereby correcting the jitter due to rotation variance of a rotary polygonal mirror with a high precision.

Title: Initial loading core or reactor
Inventor: YOSHIDA NORIYUKI
IPC: G21C3/62
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To improve fuel economy and make core characteristic of a first cycle good, by loading a type B fuel assembly in only the outer area of a core. SOLUTION: Structure of a reactor from outermost periphery of a core 7 to a three-layer is determined as an outer area 16, and the inside is a middle area 15. In the initial loading core, number of flammable poisonous fuel rods is small, and a type B fuel assembly 12 being a high enriched fuel assembly in which the number of the flammable poisonous fuel rods in which flammable poison enrichment is 1 wt.% or lower is large, is loaded in only the outer area 16 of the core 7. Thus, in an initial cycle, output in the outer area 16 is low, and the maximum linear heat rating and the minimum critical power ratio are moderate. In addition, since the flammable poison enrichment is burned quickly, the subsequent output is increased, core radial output distribution is flattened, and the maximum linear heat rating and the minimum critical power ratio are rationalized.  In addition, since control rod value is small, reactor stop margin can be improved. Therefore, even if the ratio of the high enriched fuel assembly is heightened, core characteristic is nor worsened.
