Title: Power factor improving converter circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M1/42
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To downsize a converter circuit at low cost and improve electric property such as power conversion efficiency, etc. by improving the power factor, based on the switching output being fed back from a series resonance circuit to a rectified current path. SOLUTION: The switching output of a current resonance type converter is supplied to the primary winding N1 of a magnetically coupled transformer MCT, and the AC voltage in switching cycles is transmitted to secondary winding N1 . By the switching voltage of the secondary winding N1 , the switching voltage is superposed on the rectified output voltage through a rectified path. And, the rectified currents are intermitted in switching cycles by a high-speed recovery type diode D2 . And, a power factor improving converter 10 performs charge to a smoothing capacitor C1 in condition that the switching output is superposed on the rectified output voltage, and pulls down the voltage across the smoothing capacitor C1 in switching cycles. Therefore, a charge current flows even in the period when the level of the rectified output voltage is lower than that of the voltage across it, so power factor is improved.

Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To allow a user to feel a nearly natural change in the air current by providing a deflection velocity chaos fluctuation data generation means which generates deflection velocity data and fluctuating chaotically the velocity of wind without allowing the user to feel cooled air at a specified indoor position during cooling operation. SOLUTION: While the temperature of an air current diffused from an indoor unit of an air conditioner 4 is detected with an outlet temperature detection means 1 and output to a ventilation velocity determination means 3, differential temperatures of the output values from a room temperature detection means 11 and a temperature setting means 12 are computed with a differential temperature detection means 11, thereby outputting the computed values to the deflection velocity determination means 3. The determination means 3 makes it possible to set a deflection velocity which fluctuates the velocity of wind chaotically at a specified indoor position based on the input signal so that no user may feel cooled air and enables the user to feel changes in air current which air almost natural, and output the value to an air conditioner 4, thereby controlling a deflection blade.

Abstract: PURPOSE:To prevent occurrence of ring artifact or the like on a reproduced image by fixing a substrate on a fixed frame with an upper face of the substrate as reference. CONSTITUTION:Outer walls 102, 104, 105 protect an element block 210 and a substrate 205 against external environments.

Title: Heating resistor type air flowmeter
Inventor: ITSUJI TAKAYUKI
IPC: G01F1/68
Filed: 1993-12-07
Abstract: PURPOSE:To make it possible to carry out zero adjustment and span adjustment independently by providing an output regulating circuit with a subtractor having one input receiving an output signal from an amplifier and the other input terminal receiving reference voltage. CONSTITUTION:A heating resistor 1 and a temperature-sensitive resistor 2 are set in an air channel 30. A reference resistor 4 for converting the current flowing through the resistor 1 into a voltage and resistors 5, 6, 7 constitute a bridge circuit. The bridge circuit and the resistors 1, 2 control a transistor 3 through differential amplifiers 8, 9 so that the resistor 1 constantly exhibits a predetermined temperature with respect to the air temperature. Consequently, the current flowing through the resistor, and thereby the terminal voltage V0 thereof, varies according to the air flow rate when the temperature of the resistor 1 is controlled at a constant level. An output signal is delivered from a noninverted amplifier 11 to one input terminal of a subtractor 18 in an output regulating circuit 101 having the other input terminal receiving an output from a voltage follower 21 for maintaining a constant reference voltage. Consequently, zero- adjustment can be effected independently of span adjustment.

Title: High-speed logic circuit
Inventor: KATO KOJI
IPC: H01L21/82
Filed: 1989-11-27
Abstract: PURPOSE:To attain impedance matching regardless of whether a signal is an input or output signal by using one of the two pads for the signal and the other for terminating resistance connection only when the signal is the input signal. CONSTITUTION:The input signal SIN which is supplied from a terminal 1 and passes through a transmission line 2 is supplied to an internal circuit 11 through the path of a pin 4, a lead 5, a bonding wire 6, and a pad 7. Further, it is terminated to a power line 19 through the path of the pad 7, a pad 12, a bonding wire 14, a lead 13, a pin 15, a transmission line 17, and a resistor 18. On those signal paths, parts where impedance can not be controlled sufficiently are the parts of the bonding wires 6 and 14 and pads 7 and 12. Mismatching of impedance at those parts, however, is not a large problem, so the impedance matching is attained. Namely, the pad 7 is used for the input signal and the other pad 12 is used for the terminating resistance connection, so folding termination is performed and the impedance matching is formed.

IPC: H03M3/02
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To obtain an A/D converter where a DC offset is stably eliminated. SOLUTION: An input audio signal X is given to a subtractor 1, where the signal X is subtracted by an output of a 1-bit D/A converter 5, and the resulting signal X' is given to an integration circuit 2, where the signal X' is integrated. An output U of the integration device 2 is compared with an output U corresponding to one preceding clock by a comparator 3, and an output Y of the comparator 3 is delayed by a one clock delay device 6 and given to the 1-bit D/A converter 5, and then fed back to the subtractor 1. Thus, the input audio signal X is sequentially ADD-converted for each clock and a 1-bit serial digital audio signal is obtained as the output Y of the comparator 3. A BPF 4 receiving the output Y applies integration, arithmetic operation and elimination of an undesired signal to the signal Y and outputs a multi-bit digital audio signal DO. Furthermore, a band pass characteristic is provided to the BPF 4 which eliminates a DC component.
