Title: Reference value correcting device in driving wheel slip control device
Inventor: YAMAMOTO OSAMU
IPC: G01P3/56
Filed: 1994-12-20
Abstract: PURPOSE: To obtain the reference value accurately even during the turn of a vehicle to enable control by computing the correction value on the basis of body speed and a steering state when the turning radius of a driving wheel is different from the turning radius of a driven wheel, and correcting the correction value for controlling the slip state of the driving wheel, with the computed correction value. CONSTITUTION: In a control unit U to which the output signals of wheel speed detecting means IRL-ILR respectively provided at four wheels are inputted, driving wheel speed and body speed are obtained, and the slip factor of the driving wheels is computed on the basis of the obtained value. The slip factor is compared with the reference value for slip control to estimate the slip state of the driving wheels, and the opening of a throttle valve 7 is adjusted by a pulse motor 6 to control driving torque. In this case, the reference value is computed on the basis of the body speed, and when a vehicle is detected to be in a specified turning state from the output of a steering angle detecting means 3, the reference value is corrected by the correction value based on the body speed and the steering state.

Title: Digital phase locked loop
Inventor: ISHIZAKI HIROYUKI
IPC: H03L7/06
Filed: 1994-12-20
Abstract: PURPOSE: To eliminate the need of a digital PLL circuit provided with the oscillation circuits of different frequencies for respective transmission rates by generating signals synchronized with the digital signals of the plural transmission rates by one kind of clock signals. CONSTITUTION: The respective inversion intervals of digital input signals DIN are counted in counters 1-4 based on the clock signals MCK. The final count value of the respective inversion interval becomes a value corresponding to the multiple of a minimum inversion interval. That is, when the standard count value of the minimum inversion interval is defined as a reference count value, the final count value of the respective inversion intervals becomes the multiple of >=1 of the reference count value. Decoders 7-10 output the value corresponding to the count value.  For instance, when a part from an initial value to the half of the reference count value is made to correspond to '0,' the remaining half is made to correspond to '1' and '0' or '1' is made to correspond to the respective count values in the same cycle thereafter, the output of the decoders 7-10 becomes the signals for which the minimum inversion interval is one cycle synchronized with the signals DIN and turned to synchronizing signals.

Title: Oxidation preventing coating film
Inventor: KINGETSU TOSHIKI
IPC: C30B29/36
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain a coating film inhibiting the formation of cristobalite in an oxidizing atmosphere at a high temp., suppressing the progress of oxidation toward the interior and having enhanced oxidation preventing performance by diminishing <111> oriented grains in a polycrystalline β-silicon carbide coating film preventing the oxidation of a substrate formed by a chemical vapor phase reaction-vapor deposition method. SOLUTION: The fraction of <111> oriented grains in a polycrystalline β-silicon carbide coating film is made lower than that in a random oriented polycrystalline body. When the polycrystalline β-silicon carbide coating film formed on a graphite substrate by a chemical vapor phase reaction-vapor deposition method using gaseous SiCl4 , CH4 and H2 is exposed to an oxidizing atmosphere at >=1,500% deg.C, cristobalite having a high coefft. of thermal expansion as well as amorphous SiO2 is formed. Since the formation of cristobalite depends on the amt. of <111> oriented grains in the β-silicon carbide coating film, the oxidation preventing ability of the coating film is enhanced by diminishing <111> oriented grains.

Title: Semiconductor device and manufacture thereof
Inventor: KUSUNOKI SHIGERU
IPC: H01L29/78
Filed: 1990-11-21
Abstract: PURPOSE:To eliminate the need for the boring of contact holes to gates and source or drain regions simultaneously, to lower source/drain resistance, to reduce parasitic capacitance and to increase working speed by forming the gate electrodes and source or drain regions of different MOSFETs of the same substance. CONSTITUTION:When the gate electrode 3041 of a first MOSFET 1 and the drain or source region 3102 of a second MOSFET 2 are connected, the active layer 3082 of the second MOSFET is formed by using the same material as the gate electrode 3041 of the first MOSFET 1. Consequently, connection to both the gate electrode 3041 of the first MOSFET 1 and the active layer 3082 of the second MOSFET 2 by contacts is avoided by unifying and forming the gate electrode 3041 and the active layer 3082 by the same material, and the drain or source region 3102 may be connected to one of them. Accordingly, the boring of a contact hole to a gate and the source or drain region is unnecessitated simultaneously, the resistance of source/drain is lowered, parasitic capacitance is reduced, and working speed is increased.
