Title: Tuner for reception of satellite broadcast
Inventor: KINUGAWA TOSHIMITSU
IPC: H04N5/44
Filed: 1989-04-07
Abstract: PURPOSE:To prevent interference due to a leakage signal from generation even when the voltage of a high frequency signal is low by providing an AGC circuit to control both the attenuation factor of an attenuator and the amplification factor of an amplifier. CONSTITUTION:The attenuation factor of the attenuator 8 and the amplification factors of an intermediate frequency amplifier 13 and the amplifier 16 are controlled by the output signal of the AGC circuit 15. In other words, when the high frequency signal Sr with a low voltage is inputted from an input terminal 6, both the attenuation factor of the attenuator 8 and the amplification factor of the amplifier 16 are decreased, and a local oscillation signal is amplified a little by the amplifier 16, and is mixed with the output signal of the attenuator 8 at a mixer 11, and also, part of it appears as the leakage signal S'o at the input terminal 6 after passing the attenuation 8 and a high frequency amplifier 7. Thereby, the voltage of the leakage signal is low when the voltage of the high frequency signal is low, which prevents the leakage signal from going to an interference signal for another receiver.

Title: Hollow casting structure
Inventor: NORO HIROSHI
IPC: B60B3/06
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To install a strut in the hollow part of a casting in a satisfactory formability. SOLUTION: An interval between both symmetrical sidewalls 5 constituting the hollow part of a hollow hub in a cast wheel 1 and being opposed to each other is connected together with a tubular strut 8 and constant in wall thickness, controlling each resonance in these sidewalls 5 and in the hollow part and thereby reducing the extent of noise. When casting the wheel, this strut 8 is set up in a cavity so as to be concentric with an axle in a state that it is preset in a core for forming the hollow part and then cast therein whereby it is residually integrated in the hub. Therefore, since the strut 8 gets off without being forming with the core, there is no need to consider any castability to the core and its aligning accuracy, so that formability is improved, and since it is formable into the constant wall thickness at the minimum diameter, the whole lighteningness is thus realizable.

Title: Discharge lamp lighting device
Inventor: KOMATSU HARUKI
IPC: H05B41/24
Filed: 1993-03-10
Abstract: PURPOSE:To provide a lighting equipment which is tender to human eyes in such a way that brightness is gradually changed into specified one. CONSTITUTION:A discharge lamp 4 is started by a LC series resonance circuit, and lamp current after the lamp has been lighted, is determined by a choke 6. A represents a brightness switch-over circuit for full lighting, and B represents a brightness switch-over circuit for dimming. Turn-on timing by a transistor Q3 is faster than that by a transistor Q2. A CR time series circuit changes oscillating frequency (f) with resistors 30 and 16 made variable by making use of the charge/discharge of capacitors 16 and 26. When the discharge lamp is to be started so as to be fully lighted, as soon as an AC power supply 1 is turned on, an oscillator 10 starts oscillating, charging to the capacitor 16 is started, current in the resistor 30 is thereby gradually decreased, oscillating frequency (f) is gradually lowered, resonance of a capacitor 5 with the choke 6 is intensified because a transistor 13 is turned on, the discharge lamp 4 is lighted, and the discharge lamp 4 keeps lighting at a low value of current until the capacitor 16 is fully charged. When the transistor 13 is turned off, the oscillating frequency (f) starts gradually lowering, and lamp current finally comes up to a level of full lighting.

Title: Keyboard switch
Inventor: MIYAMOTO TAKAO
IPC: H01H13/712
Filed: 1989-04-06
Abstract: PURPOSE:To realize a compact size of the device and to improve the operating property by making the switching operation member of a keyboard visualized with a transmitted light. CONSTITUTION:When a light source 8 is lighted by a passing power operation or the like, the light is radiated in a transparent plate 6. And since light- transmissible bolcks 5 geared and held in a cutting window maintains the surface-contact to the peripheral surface of the cutting of the cutting window, the light transmitting in the transparent plate 6 is transmitted into the transmissible blocks 5 through such a surface-contact. Although the transmissible blocks 5 are covered with an untransmissible coverage material 7 at the upper side same as the transparent plate 6, light-transmissible switch marks 1-3 are processed on the upper position. As a result, when the light in the block bodies 5 is leaked through the transmissible parts, the switch marks can be read by the form of the light leakage, and the keyboard can be composed in a thin form.

Title: Method and equipment for injecting nitrogen oxide inhibitor into flue gas of boiler
Inventor: RICHIYAADO SHII BETSUTARITSUKU
IPC: F23J15/00
Filed: 1994-04-06
Abstract: PURPOSE: To develop a technique for injecting a NOX inhibitor at a position with a proper temperature zone. CONSTITUTION: In order to disperse a NOX inhibitor in a furnace chamber 16 or a convection compartment 18 of a boiler 10 there are employed a movable conduit 22 and a dispersion nozzle 24 inserted thereinto. The NOX inhibitor inhibits optimally production of NOX in a predetermined temperature zone. A temperature sensor 26 is disposed on a conduit for detecting flue gas temperature.

IPC: G01R29/02
Filed: 1991-04-22
Abstract: PURPOSE: To reduce a DNL by setting the MSB of a digital-analog converter(DAC), when a comparison result from a comparator exceeds a full scale of an analog-digital converter(ADC), subtracting 1st and 2nd inputs of an adder means, and generating a comparison output within the range for the DAC. CONSTITUTION: A digital adder 30 calculates 2's complementary sum, so that a count is reduced from an output of the ADC 28, and an output 32 is a digital conversion amount of an analog input at a terminal 15. An adder 14 adds two amounts in excess of a full range of the A/D converter 28, and when an MSB terminal of the DAC 22 is set, a terminal 25 of a threshold level comparator 26 is connected to a carry-in input terminal of the adder 30, where normal sum is taken. As a result, a proper digital output DOUT is obtained from the adder 30 again. The regular subtraction or downward averaging processing in an adder 14 is conducted as a result of an addition between an input voltage and a DAC voltage in excess of a dynamic range of the ADC 28. Thus, the threshold level trigger input point with respect to the ADC 28 is continuously changed, and no modulation circuit averaging threshold level points is required.
