Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To convert a low level logic signal into a high level logic signal without making the circuit complicated and to minimize the complexity of the circuit, signal delay and power consumption. SOLUTION: A low power logic signal level converter 12 provides an output of an output logic signal 13 whose level is converted in response to an input logic signal 11 and has a CMOSFET current mirror differential amplifier with a current control element so as to avoid induction of a current entirely during a steady-state operation of the circuit. The CMOSFET current mirror differential amplifier has a PMOSFET current mirror operated by an NMOSFET pull-down transistor(TR) and a PMOSFET is provided between current mirror TRs to interrupt a DC. The PMOSFET to be inserted interrupts a DC during the circuit steady-state operation without giving adverse effect onto a line exciting capacitance of the current mirror differential amplifier.

When the result is larger than the predetermined threshold value, the input signal at the existing time slot is discriminated to be an excessive input signal such as clock noise, and the discharge time constant of a time constant circuit 18 is set to a small value for a prescribed time. The discharge time constant of the 2nd memory value stored in the 2nd memory circuit is switched at the signal of the normal input level to apply the AGC operation corresponding to each signal.

Title: Parallel operation circuit for power source
Inventor: KYO HIROYUKI
IPC: H02J3/38
Filed: 1992-06-29
Abstract: PURPOSE:To prevent a cross current of a power source in a parallel operation circuit for supplying powers from a plurality of power sources to one load. CONSTITUTION:A current deviation of an output current of one power source P1 from a load current per one power source detected from an entire load current to be supplied to a load 1 is detected by a current deviation detector 21. When the deviation is continued for a predetermined time to be a first set value or more, a first comparator 25-1 outputs a signal. When the deviation is instantaneously a second set value or more, a second comparator 25-2 outputs a signal to disconnect the power sources. Thus, since the power sources can be disconnected in response to a normal time or a transient time, an increase in damage, loss of an element due to a cross current can be prevented.

Title: Processing method of digital and analog input signal and circuit
Inventor: FURITSUTSU BUAISAA
IPC: H03D3/24
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To process digital and analog input signals with one circuit by allocating components which process an input signal to a controllable oscillator with a switchable means in each case. SOLUTION: Components of an analog or digital input circuit are connected to a controllable oscillator VCO by a switchable means in each case. When an analog signal appears at an amplifier 1, switches S1 and S2 are at a position I. A signal from a loop filter F flows to the oscillator VCO through the switch S2 as a signal from a phase comparator K flows to the oscillator VCO through the switch S1. Also, when a digital input signal appears at an amplifying stage 1, the switches S1 and S2 are at a position 0. The oscillator VCO is externally supplied by a signal that is obtained from a crystal-high precision control loop. Then, the oscillator VCO oscillates regardless of an input signal.

Title: Humidifier
Inventor: WADA TSUYOSHI
IPC: F24F6/02
Filed: 1990-07-24
Abstract: PURPOSE:To reduce a damage of a burn and to enhance a visual sensing effect during humidifying operation by heating a heating oven by a heater to generate steam, feeding the air by a blower and diffusing it together with the air out of a body in a state that the temperature of the steam is lowered. CONSTITUTION:When water in a heating oven 3 heated by a heater 5 is boiled, it becomes steam particles to be filled in an atomizing cylinder 7. The air from a blower 6 is fed from the opening 7a of the cylinder, and the particles are guided from a diffuser 8 out of the body. In this case, the steam fed out of the diffuser 8 is cooled to about 70 deg.C. Accordingly, in comparison with the case that the steam is directly diffused, a danger of a burn can be reduced. Since a steam generating amount is apparently increased due to agitating by the air and its rising speed is increased, the visual sensing effect of humidifying operation can be enhanced.

IPC: H01L21/3205
Filed: 1987-08-05
Abstract: PURPOSE:To prevent encroachment on a surface of a semiconductor substrate by a metal layer without increasing contact resistance, by previously forming a semiconductor layer of approximately the same quantity as that of the encroachment on a bottom surface in a contact hole before the metal layer is selectively grown in the contact hole. CONSTITUTION:A diffusion layer 2 and an insulating layer 3 comprising SiO2 are selectively formed on a surface of a semiconductor substrate 1 and the contact hole 4 is formed in the insulating layer 3 such that the surface of the diffusion layer 2 may be open. Then, a polycrystalline silicon layer 5 having the same thickness as that encroached by a wiring film to be formed in a next step (for example, 0.2-0.3mum) is formed on a bottom surface of the contact hole 4 by selective vapor growth. Thereafter, a wiring layer 6 formed of tungsten W is formed in the contact hole 4 by the selective vapor growth. At the time, the polycrystalline silicon 5 is encroached and disappeared by absorption by the wiring layer 6, but the vapor growth is over before the diffusion layer is encroached. As a result, it is possible to prevent the encroachment on the surface of the semiconductor substrate by metal layer without increasing contact resistance.
