Title: Digital processing quadrature modulating method and quadrature modulator
Inventor: OKADA TAKASHI
IPC: H04L27/36
Filed: 1994-08-05
Abstract: PURPOSE:To reduce the circuit size without adding complicated control to a digital filter by designing the phase characteristic of the digital filter so as to shift it by a half of a timing phase difference between channels, and inverting the time axis and using a tap coefficient. CONSTITUTION:An input signal of each channel is shaped at its waveform by a waveform shaping digital filter 1 and then outputted in each channel. Output signals from the filter 1 in each time slot are synthesized through complement circuits 201I, 201Q and a multiplexer 202 in prescribed order to obtain a modulated output. In order to compensate a phase difference due to signal synthesis, the phase characteristics of respective channels are uniformly shifted right and left by a half of a timing phase difference between respective channels which is generated by quadrature modulation operation using digital processing, the time axis is inverted and the same filter circuit is used from both directions so that a phase difference corresponding to the timing phase difference is applied between the input signals of both the channels.

Title: Production of oxide superconductor
Inventor: ICHINOSE HIROOMI
IPC: H01B12/00
Filed: 1991-07-19
Abstract: PURPOSE:To provide a method for producing an oxide superconductor capable of making large size products enabling to attain densification of critical electric current and highly improved floating forces, respectively, and capable of greatly improving a floating force per unit area. CONSTITUTION:Since BaCO3 and CuO are heated-melted at a temperature below the melting point of Y2O3 in the first step, the BaCO3 and the CuO are melted- quenched without the charge of Y2O3. In the second step, the solidified raw material is compounded with Y2O3, ground and mixed, thereby permitting to prevent the generation of the agglomeration phenomenon of the Y2O3 in the melt, in other words, to form a non-conductive phase Y (211) of a homogeneously dispersed state, and to strenghthen a pinning force.

IPC: F16C11/00
Filed: 1988-08-17
Abstract: PURPOSE:To improve the extent of reliability as well as to make the cost of production cheaper, by forming a portion different in curvature in a part of a curved surface. CONSTITUTION:A plane part 3 different in curvature is formed in the head center of a semispherical part 1 consisting of a ceramics sintered body. With this formation, a gas escape port being interconnected to a part forming this plane part 3 is formed in a die whereby gas is made escapable to the outside so that any defective due to the presence of this gas in the spheric part 1 can be prevented from occurring, thus the reliability is improved. In addition, since it will do that such a gas escape port is merely formed in the die, the manufac turing cost of the die comes to be cheaper.

Title: Fabrication of semiconductor integrated circuit device

IPC: H01L21/8238
Filed: 1992-07-31
Abstract: PURPOSE:To facilitate micromachining by surrounding a layer to be surrounded with side and lower surrounding layers coupled through heat treatment while isolating from a first conductivity type impurity layer and a semiconductor substrate. CONSTITUTION:An n-layer (side surrounding layer) 9 and an n-well (lower surrounding layer) 10 are formed individually. The n-layer 9 and the n-well layer 10 are then coupled through heat treatment to surround a first p-well 11 which is thereby isolated from a second p-well (first conductivity type impurity layer) 12 and a p-type silicon substrate 1. Consequently, the n-layer 9 for isolating the first and second p-wells 11, 12 can be formed without using a region having n-type concentration gradient. This method allows arbitrary setting of the depth of n-type regions 9, 10 and the isolation width between the first and second p-wells 11, 12 thus facilitating micromachining.

Title: Line thermal printer
Inventor: ISHIWATARI TOSHIO
IPC: B41J13/10
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent generation of slippage between paper sheets which is easy to generate during printing using a thermal head for multi-sheet paper formed by being overlapped a plurality of heat sensitive color sheets. SOLUTION: This printer is formed so that the traveling passage 12a of multi-sheet paper conveyed by a platen 14 and passing through a nip part 16 between the platen 14 and a thermal head 15 may be bent to the platen 14 by a regulating member 19 disposed near the more downstream side of a paper passage 12 than the nip part 16. As a result, the multi-sheet paper is curled to the thermal head 15 by a thermal effect caused by heat generation of a heater of the thermal head 15, so that a phenomenon that heat sensitive color sheet on the platen is easy to travel ahead of heat sensitive color sheet on the thermal head 15 side can be avoided, thus it is possible to prevent generation of slippage between paper sheets in the multi-sheet paper.

Title: Predictive fusing device and method

IPC: G03G15/20
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To control the temperature of a heating element in an imaging device by selecting delta temperature when desired temperature is set and a timing signal is received and adjusting the temperature of the heating element to the desired temperature corrected. SOLUTION: The input of the desired temperature to an adaptive system 300 is corrected by predicting next heat load. The heat load is compensated by the system 300, so that the temperature of the fusing device is stabilized at the desired temperature. When some time elapses after a medium enters a fusing system, the system 300 increases power amount supplied to the fusing system in response to the drop of the fusing temperature. Finally, the power amount supplied to the fusing system is stabilized at a new power level by the system 300. In such a case, a switch 402 is designated that the desired temperature must be corrected for specified time before the medium enters the fusing system according to a paper path timing signal.

Abstract: PROBLEM TO BE SOLVED: To reduce an influence of cross regulation on non-controlled voltages, along with a small variation range of a switching circuit and a switching control circuit on a primary side of a transformer, by making a control voltage constant under control, regardless of the variation in the load current. SOLUTION: A reference voltage 23 is set previously with respect to a detection signal level from a current detection circuit 20 when a maximum current is carried in a control voltage load circuit. Then, the current detection signal level, which is generated according to the current value detected by the current detection circuit 20, is compared with the reference voltage 23. On the basis of the result, a control voltage and current divider circuit 21 is controlled in such a way that the sum of a current flowing through the control voltage and current divider circuit 21 and a current flowing through the current detector circuit 20 is made equal to the maximum current of the control voltage load circuit.
