Title: Output circuit
Inventor: OGA GENICHIRO
IPC: H03K19/0175
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To enlarge the width of maximum voltage and minimum voltage in an output terminal and to realize a wide dynamic range by installing a voltage level shift circuit between the output of a load current detection push pull circuit and the collector output of a current amplifier circuit and supplying reference voltage to the push pull circuit through a resistor. SOLUTION: When the voltage of an input signal VINa increases and output voltage becomes maximum, a resistor R15 is connected between the emitter common connection point of the transistors Q11 and Q12 and the collector common connection point of output transistors Q14 and Q16. Two connection terminals are not directly connected by the resistor R15 and voltage is adjusted. Since the resistor R15 exists, the commonly connected collector potential of the transistors Q14 and Q16 can be raised to voltage obtained by subtracting collector saturation voltage Vcesat from power source VCC and a dynamic range becomes 1a. When voltage is reduced voltage derived to an output terminal VOUTa can be enlarged to Vcesat.

Title: Discharge lamp lighting device
Inventor: MIYAZAKI MITSUHARU
IPC: H05B37/02
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To maintain the straight discharge arc over the full lighting period by setting the lighting frequency higher than the acoustic resonance frequency at the time of rated lighting, and amplifying the amplitude of the compression wave generated from the arc. SOLUTION: A frequency changing means 5 and a lamp current changing means 6 change the effective value of the lighting frequency and the lamp current in response to a change of the lamp impedance detected by a lamp characteristic detecting means 4. When a lamp 1 is lighted, the lamp impedance gradually rises from a low level to a level of the rated lighting. The lamp current waveform corresponding to the lamp impedance detected by the lamp characteristic detecting means 4 is supplied to the lamp 1.  The current waveform supplied at this stage lowers the lighting frequency to the rated lighting after the lighting similarly with a change of the acoustic resonance frequency for straightening the discharge arc, and furthermore, the current more than the rated lamp current is supplied at the initial time of lighting, in which the vapor pressure inside of a discharge space is low, so as to amplify the amplitude of the compression wave generated from the arc and enlarge the excitation level of the acoustic resonance.

Title: Air conditioner
Inventor: MORIMOTO MOTOO
IPC: F24F11/02
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To dry the inside of an indoor unit while suppressing rise of temperature in a room where the indoor unit of an air conditioner is installed as much as possible, by providing a drying operation function operating a space heating operation function before operating a blowing operation function. SOLUTION: The operation contents of a drying operation comprise an initial space heating operation (t1 hour) and a continuous blowing operation (t2 hours). That is to say, the purpose of the space heating operation (t1 hour) is not high- temperature sterilization by warm air, but an avoidance of evils caused by leaving a cooled heat exchanger and ventilation path as they are at low temperature, since the blow by a fan stops at the time when the operation is stopped although what is arranged around a low-temperature member such as a filter that is located in the windward side of an indoor heat exchanger at the time of space cooling becomes a temperature close to room temperature, the temperature of the filter goes down close to the temperature of the indoor heat exchanger by low-temperature radiation, and relative humidity is raised so that mist is attached to the filter,  and there is an evil that mold is formed by having this mist as a hotbed. The rise in the relative humidity around this low-temperature member is prevented.

Abstract: PURPOSE:To simplify a circuit by sending a data to a speech path while the signal of a predetermined frequency is intermitted and forming and demodulating an output signal when the oscillation frequency is coincident with the frequency of the signal inputted from the channel at reception. CONSTITUTION:The oscillator 14 is oscillated at a prescribed frequency.

In sending the data, when the output terminal P0 goes to a level 0, the TR 6 is turned off, the output of the oscillator 14 is amplified by a TR 7 and sent to the channel 11. Thus, the data of tone burst form is sent to the speech path 11 in such a manner. An incoming signal is given to a filter 12 to transmit high frequencies at reception, amplifiered (2), compared with the frequency of the oscillator 14 by a comparator 15, and when they are coincident, the result is inputted to a control means 5 for demodulation. Thus, the number of components is reduced to simplify the circuit.
