Title: Microgyroscope
Inventor: BOKU KEIYON
IPC: G01C19/5755
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To sense a shift of a vibrating structure because of a Coriolis force by a sensing means arranged on the same plane as the vibrating structure, by sensing the motion of the vibrating structure vibrated in one direction with static electricity by a driving means through a capacitance change. SOLUTION: When an alternating current voltage equivalent to a natural frequency is impressed to a driving device 33, vibrations are generated in an X-axis direction by static electricity between combs 39 and 40. As a result, a vibrating structure 50 receiving a driving force is vibrated with the natural frequency. In order to maintain the vibrating motion with the natural frequency, a sensing device 34 senses the vibrations and generates a voltage sufficing an instable emission control condition on the basis of the sensed motion. The voltage is impressed to activate the driving device 33. A shift of the structure 50 invites a change of a capacitance formed between a sensing electrode 38 and a coupling part 36. The shift of the structure 50 in a Y-axis direction can be detected by calculating a difference of capacitance generated at an anode and a cathode of the sensing electrode 38.

Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent an increase of cable net number especially the increase of printed wiring board, by providing a periodical operation means also in a delay generator, and giving fraction data to a delay operation means in resonance with period initiation data from the period generator. SOLUTION: A period operation means 3 is added for constitution on a delay generator 2i and the fraction data of the operation results of the period operation means 3 is given to a delay operation means 11. Thus, the fraction data transmission line to a delay generator 2i from a conventional period generator 1 is eliminated and the transmission line is reduced to only 1 bit line of a period initiation data. When a start signal is inputted in an input terminals a0 of the period generator 1 and the delay generator 2i, a latch circuit g1 is turned on and a latch circuit 5 of the period operation means 3 is cleared. By the next reference clock, a latch circuit g2 is turned on and the latch circuit 5 latches the period data of the operation results. At this moment, integer data only is utilized in the period generator 1 and fraction data only is utilized in the delay generator 2i.  The rest part is the same as before.

Filed: 1999-12-08
Abstract: PROBLEM TO BE SOLVED: To provide the polycrystalline silicon resistance element of high performance and high resistance, which has the less fluctuation of a resistance value by Al wiring thermal treatment. SOLUTION: The polycrystalline silicon film 12 of about 150 nm is formed on a field oxidized film 11 formed on a silicon substrate 10 by a CVD method. N-type impurity (phosphorus, for example) and P-type impurity (boron, for example) are ion-implanted into the polycrystalline silicon film 12 so that total concentration in polycrystalline silicon becomes not less than 1×1020 cm-3. Phosphorus is ion-implanted so that impurity concentration becomes 1.7×1020 cm-3 and boron is ion-implanted so that impurity concentration becomes 2×1020 cm-3. The total concentration of N-type impurity and P-type impurity, which are thus implanted, becomes 3.7×1020 cm-3 but they are mutually canceled. Thus, only 3×1019 cm-3 of P-type impurity contributes to conduction and high resistance whose specific resistance is about 1×10-1 Ω.cm can be realized.

Abstract: PURPOSE:To provide the fading distortion compensator which enables high-accuracy compensation. CONSTITUTION:Concerning the fading distortion compensator provided with distortion value detecting parts 8-11 for detecting the distortion of a pilot symbol at the respective sub carriers of communication to use a multi-carrier and time base interpolating parts 13-16 for estimating the distortion of an information symbol at the respective sub carriers, this device is provided with a distortion estimating means 12 for estimating the distortion values of the respective sub carriers at the same time based on the detected values of the distortion value detecting means 8-11 and for presenting those values to the time base interpolating parts 13-16. When the distortion value of the pilot symbol is detected at a certain sub carrier, the distortion estimating part 12 estimates the distortion values of the remaining sub carriers and presents those values to the time base interpolating parts 13-16. Therefore, the quantity of information to be utilized for the time base interpolation of distortion values at the time base interpolating parts 13-16 is increased, and the intervals of symbols to apply the distortion values are shortened. Thus, the time base interpolation of distortion values can be more exactly performed, and high-accuracy fading distortion compensation can be executed.

Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a structure for resistance layer which can give a charge distributing function to a resistance layer and, at the same time, can excellently adapt to the multiplexing of the resistance layer. SOLUTION: Voltages are applied across assembled electrodes 26-32 and a gate electrode 14 and the voltage applied across the electrode 14 reduces the resistance value between a storage node 20 and the electrodes 26-32 and the voltages applied across the electrodes 26-32 generate electric currents to an amorphous silicon layer 34. The electric currents generate charges which spatially change on the node 20 and charges. When the voltage applied across the electrode 14 is discontinued, the resistance value of the layer 34 abruptly increases and traps the charges on the node 20. The trapped charges and an electric field obtained from the charges are stored for a long period and, when a low voltage is applied across the electrode 14, the voltages applied across the electrodes 26-32 change without disturbing the charges on the node 20.

Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of its step by suppressing the occurrence of defects at mounting to the utmost, without causing thermal deformation at mounting. SOLUTION: A mold package 12, which has thermal two-layer structure and in which a warpage arises in the normal direction at the thermal boundary face of the two-layer structure, is assertively given a shape of a warpage.
