Title: Variable delay line
Inventor: KAMETANI KAZUO
IPC: H03H7/30
Filed: 1987-06-10
Abstract: PURPOSE:To match the impedance of a variable impedance element over a wide variable range of delay time by connecting a nonlinear circuit which outputs a 2nd control signal for varying the impedance to the variable impedance element. CONSTITUTION:Even if a 1st control signal Vd from a signal source DAC varies and the characteristic impedance varies with the delay time of a delay line DL, the 2nd control signal Vg from the nonlinear circuit varies the impedance of a field effect transistor TR equally to that of the delay line DL. Consequently, the delay time can be varied with one control signal while the impedance is matched as it is, and a reflected wave is hardly generated on the delay line to secure the speediness.

Title: Air conditioner
Inventor: SAKAI HIROAKI
IPC: F24F1/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To assure total pressure characteristics of a centrifugal blower by reducing a pressure loss caused by a local sudden expansion of an air supply passage when air is transferred from an air outlet to a duct in an air conditioner in which the duct for air transfer is connected to the air outlet. SOLUTION: In an air conditioner, a duct flange 5 is provided around an outer periphery of an air outlet 2 and such a duct flange 5 has its opening area greater than the opening area of the air outlet 2. A nozzle 8 which expands its opening area by inclining a lower surface of an outlet 7 of a centrifugal pump 3 downwardly to an angle which does not give rise to an influence of turbulence of air flow is provided. Owing to such a construction, a pressure loss caused by a local sudden expansion of an air supply passage when transfer air moves from the nozzle 8 to the duct 6 can be reduced thus providing the air conditioner which can assure the total pressure characteristics of the centrifugal blower.

Title: Transistor output part
Inventor: AZEGAMI TADASHI
IPC: G05F1/571
Filed: 1984-07-12
Abstract: PURPOSE:To attain the large switching capacity by using the 1st and 2nd voltage limiting means to prevent the overrise of voltage of an internal circuit and the voltage between external terminals respectively and absorbing the counter electromotive force produced by the load by an output transistor. CONSTITUTION:The emitter and the collector of a transistor TRQ3 are connected to an external terminal 40 and the collector of a TRQ1 respectively. Thus the current supplied from the TRQ1 is amplified by the TRQ2 and Q3. Then the base of the TRQ2 is connected to the emitter of the TRQ1, and a current limiting resistance R2 is added together with Zener diodes D1 and D2 forming the 1st and 2nd voltage limiting means. Thus the external terminals voltage is divided by a resistance R1 and the diode D1. Then the bias voltage of the TRQ1 is applied together with an operation signal 10. Thus the base current is supplied to both TRQ2 and Q4. When the signal 10 is turned off, the diode D2 limits the counter electromotive force through a load 60.

Title: Quick charge element
Inventor: WATANABE FUMIHIRO
IPC: G05F3/22
Filed: 1990-06-01
Abstract: PURPOSE:To obtain a semiconductor integrated circuit occupying a small area without using any undesired charge element by compensating the phase of a semiconductor circuit of a voltage output part and at the same time charging the capacitor for stabilization of the output as long as the output voltage does not reach a prescribed level. CONSTITUTION:A transistor TR Q1 serves as an element which performs the quick charge and the phase compensation. In a state where an output potential rises at application of a power supply, etc., the TR Q1 works as an original transistor. Thus the capacitor C is charged by an output constant current I and the TR Q1. As a result, the output voltage rises up to a prescribed level with the current I. Then the base and emitter potentials of the TR Q1 are equal to the junction capacitance applying a P-N junction used by a semiconductor because the emitter potential is set higher than the base potential. This junction capacitance works as a phase compensation capacitance of an operational amplifier used for generation of the reference voltage. Thus a boosting charge element suited to a semiconductor integrated circuit can be obtained without requiring any undesired element and area.

Filed: 1988-06-13
Abstract: PURPOSE:To draw another cable into a duct in which an existing cable is housed by installing a buoyancy body to a cable to be drawn and delivering and drawing the cable while water is injected from an incoming line terminal in the duct. CONSTITUTION:Polyethylene having an expansion ratio of 55% is mounted continuously around a cable 41 to a longitudinal positioning shape in 5.5mm thickness with a binder tape made of PVC in order to bring the specific gravity of an optical fiber cable 4 including a buoyancy body 42 to 1 or less.

Title: Mos operational amplifier circuit
Inventor: HARA YASUNORI
IPC: H03F1/32
Filed: 1990-06-04
Abstract: PURPOSE:To expand an effective through-rate while keeping the operation stability by detecting whether or not a large amplitude signal is inputted to the input and increasing the through-rate of a MOS operational amplifier circuit only when the large amplitude signal is inputted to the input and the increase in the through-rate is required. CONSTITUTION:The resistance R of resistors 10,11 is selected so that a current 2.I of a constant current source satisfies a relation of R.I=VTH, where VTH is a threshold voltage of transistors (TRs) N7, N8. Thus, a relation of I7+I8=0 exists when an identical input voltage (V11=VIN) is given to lst and 2nd input terminals 3,4 and no current flows through NMOS TRs N7, N8. However, when a difference signal is inputted to the said input terminals 3,4, a sum I7+I8 is increased. Thus, when an input signal to a differential pair is small in the amplitude, a bias current is suppressed lower and only when a large amplitude signal is inputted to the input and a large through-rate is required, the bias current is increased.
