Patent JP-H03190426-A (JP)
Title: Integrated bicmos circuit
Inventor: SAN HOO DON
IPC: H01L29/73
Filed: 1990-11-26
Abstract: PURPOSE: To avoid a voltage drop between an emitter and a collector by using a horizontal bipolar transistor having a base defined by the gate of a polycrystalline silicon. CONSTITUTION: A horizontal gate-emphasized PNP transistor(TR) 31 is formed in a BiCMOS integrated circuit together with a longitudinal NPN TR. When an input 29 is a low level, the base connection of the TR 31 is gated by the operation of a P-channel device 33 and turned to a conductive state. At the time, the base device 31 conducts a current and holds a gate at low potential and voltage can be completely pulled up to a level Vdd. When the input state of an inverter is in a reverse state, a high level signal gates the device 34 at an on state, a collector is almost held at Vss and a P-channel device 32 connects its base and emitter together to turn the device to a non-conductive state. Consequently, the function of a MOS FET can be obtained and voltage drop between the collector and emitter can be avoided.

Abstract: PROBLEM TO BE SOLVED: To improve the on-ice performance of a device in a cold district so as to cope with the increase of speed by setting a dynamic modulus of elasticity of a rubber at a specified temperature of at least grounding surface side rubber material to be installed in a driving shaft of a traveling machinery body at a specified value. SOLUTION: In order to improve the frictional force on ice, it is necessary to lower the heardness elastic modulus of a rubber at 0 deg.C or more, namely, a rubber, which can maintain softness thereof at a low temperature, is necessary. 180 kgf/cm<2> or less of dynamic modulus of elasticity E' of the rubber material in at least grounding surface side is appropriate for high-speed traveling on an icy road, and since the rubber is hard in a range at 180 kgf/cm<2> or more, adhesive force to an ice surface is lowered, and a coefficient of friction is remarkably lowered, and traction performance and braking performance to be required can not be secured. As a rubber material of the grounding surface side, polymer, natural rubber, a diene group rubber containing polybutadiene is used, and carbon black and reinforcing agent such as silica and adhesive agent are appropriately blended.  A rubber cralwer having excellent on-ice index and excellent on-ice performance at the time of real traveling can be obtained.

Title: PRODUCTION OF SILICON TETRA FLUORIDE (SiF4)
Inventor: HARADA ISAO
IPC: C01B33/107
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To obtain a high purity gas at low cost without using an adsorbent by allowing a silicon fluoride or >=2 kinds of compounds capable of synthesizing the silicon fluoride to react with sulfuric acid, from which dissolved carbon dioxide is previously removed. SOLUTION: A silicon fluoride is expressed by a general formula, MxSiF6 where M preferably represents hydrogen, an alkali metal or an alkaline earth metal. Because 0.06-0.1 cm3 carbon dioxide per 100 g 98 wt.% sulfuric acid is dissolved in the reagent grade or industrial grade sulfuric acid to cause the deterioration of purity of produced SiF4, dissolved carbon dioxide is reduced to <=2×10-3 cm3 per 100 g sulfuric acid by a method by bubbling an inert gas or heating to 50-100 deg.C or using both method in combination. Sulfuric acid free from the dissolved carbon dioxide and the silicon fluoride such as silicofluoric acid, sodium silicofluoride, calcium silicofluoride or the compound capable of synthesizing the silicon fluoride such as HF, SiO2 are fed to a reactor and decomposed to generate high purity SiF4 gas containing no carbon dioxide.

IPC: H04J13/00
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To correctly receive a signal and to prevent the occurrence of short break caused by the out of synchronism by providing a means for selecting two weighting factors and a transmission means for transmitting the signal through the use of two paths based on directivity formed by two weighting factors. SOLUTION: A transmission signal is modulated by a modulation circuit 101. A weighting factor selection circuit 103 selects optimum one or two weighting factors among plural transmission weighting factors calculated in a weighting factor arithmetic circuit 102 based on a previous information signal such as PHO shift. Product sum arithmetic circuits 104 and 105 multiply them. The transmission signals are composed in a composition circuit 106 and a frequency is converted and amplified by a radio transmission circuit 107. Then, it is transmitted from an antenna. Thus, it can be prevented that the switch operation of a timing detection circuit is not in time in a terminal even if a path is switched to that whose transmission delay largely differs and the signal is transmitted with directivity. Then, the occurrence of the short break of a reception signal can be prevented.
