Patent JP-S60165804-A (JP)
Title: Circuit for compensating oscillating frequency against temperature of crystal oscillation circuit
Inventor: HONDA KAZUHIRO
IPC: H03B5/32
Filed: 1984-02-09
Abstract: PURPOSE:To apply temperature compensation at each temperature zone depending on the type of oscillating frequency of a crystal oscillator by providing a selecting means responding to an output from a temperature detecting element, activating selectively a frequency change means thereby keeping the oscillating frequency of the crystal oscillator circuit constant. CONSTITUTION:A temperature correction circuit consists of temperature compensation circuits 4, 7 and 10. A divided voltage at a connecting point P between any of resistors of the temperature compensation circuits 4, 7, 10 and a resistor R14 is applied via a resistor R15. The resistance value of a thermister R40 is increased as temperature rises. Then a current flowing to a circuit comprising resistors R4a, R4b, R40, R14 and R15 is changed. Thus, a voltage given to a varactor diode D2 is dropped. Then the static capacitance of the varactor diode D2 is increased. The load capacitance being a combined capacitance between a capacitor C14 and the varactor diode D2 of the oscillation circuit 20 is increased in this way. Thus, the oscillation frequency is lowered.

IPC: H04B3/40
Filed: 1979-03-01
Abstract: PURPOSE:To obtain advantages in cost and maintenance only with high group frequency amplifiers for a part of relay units without providing low group frequency amplifiers, through the use of the transmission loss of coaxial cable almost proportional to f<1/2> (where; f is frequency). CONSTITUTION:Relay units 10, 12A, 14, 16A are located to the coaxial cable 20 in a suitable distance, and the relay units 10, 14 are provided with the high group frequency amplifier 30 and the low group frequency amplifier 32, and the relay units 12A, 16A are provided with the high group frequency amplifier 30 only. Thus, even with less number of the low group frequency amplifier 32, since the transmission loss at low frequency is less, the transmission signal can be transmitted over broad band in excellent manner.

IPC: C21B5/00
Filed: 1980-02-28
Abstract: PURPOSE:To improve productivity and lower the cost of iron making without accompanying the increase in fuel cost by specifying the temp. at tuyere ends and further specifying the relation between the furnace wall temp. loaded from the root part of the infurnace melt-stuck matter and the max. temp. of the furnace wall in the upper part. CONSTITUTION:In blast furnace operation, the temp. at tuyere ends is kept at >=2,500 deg.C, and the infurnace constitution of (charged iron and steel ore + charged sintered one) weight O/charged coke weight C is controlled to furnace center part > furnace wall part. Thereby, the ventilation resistance in the furnace center part is increased and the lengthening of the melt-stuck zone toward the upper place is prevented. Further, the relation between the furnace wall temp. D loaded from the root part of the infurnace melt-stuck matter and the maximum temp. of the furnace wall S in the upper part is so controlled as to assume S/D<=1. If these conditions are maintained, the shape of the melt-stuck matter stabilizes and the furnace is operated at low fuel costs.

Title: Formation of crystalline silicon film
Inventor: KODAMA NORIYUKI
IPC: H01L21/205
Filed: 1994-02-23
Abstract: PURPOSE:To prevent the roughness of the surface when crystallizing amorphous silicon by laser annealing to form a polycrystalline silicon film. CONSTITUTION:An amorphous silicon film 2 on a glass substrate 1 is irradiated with KrF excimer laser light 7A, 248nm in wavelength, and its uppermost part approx. 30nm from the surface is crystallized. In the second irradiation, KrF excimer laser with a wavelength of 486nm is used. This wavelength makes the laser light 7 pass through the polycrystalline silicon film 5C and allows almost all of it to be absorbed in the amorphous silicon film 2. That selectively rises the temperature of the amorphous silicon film 2 on the base side, and melts and crystallizes it, and consequently obtains a polycrystalline silicon film 5D having a flat surface.
