Patent JP-S59122218-A (JP)
Title: Hysteresis circuit
Inventor: SHINCHI OSAMU
IPC: H03K3/0233
Filed: 1982-12-28
Abstract: PURPOSE:To obtain stable and highly accurate hysteresis characteristics by using voltage dividing constitution and a normally on type FET, feeding back an output from a comparator comparing input voltage with reference voltage and changing resistance between the source and drain of the FET. CONSTITUTION:When both input voltage VIN and output voltage VOUT are on low levels, the reference voltage VREF is determined as voltage VREF1 by composition of resistance at ON of normally ON depression type IGFETs Q11, Q12 and low-biased IGFET Q13. When the comparator 1 detects VIN>VREF1, the output of the comparator 1 is turned from low to high level and the voltage VREF is made close to earth voltage. Consequently, the output voltage is stably kept at the high level. At that time, the voltage VREF becomes voltage VREF2 determined by the composition of resistance generated when the IGFETs Q11, Q12 and the high-biased IGFET Q13 are on, and I/O characteristics having hysteresis is obtained.

Filed: 1984-11-05
Abstract: PURPOSE:To improve the uniformity of the characteristics of a device and the reproducibility of the characteristic of a device or the acceleration of a switching speed by inserting a thin film of another metal or semiconductor between a superconductive electrode and a semiconductor to reduce the substantial height of a Schottky barrier. CONSTITUTION:Two superconductive electrodes 4 having 2-layer structure of an Nb layer 2 and an aluminum layer 3 are formed on a sapphire substrate 1. Then, a semiconductor layer 5, a gate oxide film 6, and a control electrode 7 are formed. According to this structure, since the height of a Schottky barrier formed between the semiconductor 5 and the superconductor 2 can be reduced and the osmosis of the superconductive electron pair to the semiconductor side can be facilitated, the distance of the two electrodes 4 is increased to reduce the irregular characteristics of the device. Further, since a channel conductance is improved, the switching can be accelerated. Even if a material for forming the thin metal film 3 employs Au, Sn instead of aluminum, or even if semiconductor including high impurity is used, similar effects can be provided.

Title: Method and apparatus for detecting bubble streak of glass tube
Inventor: MATSUI TADASHI
IPC: G01N21/94
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To accurately detect a bubble streak of a glass tube, by projecting a laser light perpendicularly to an outer surface of the glass tube, and detecting a light of the laser light scattered in a perpendicular direction to an axial center of the glass tube. SOLUTION: A laser 2 is arranged so that it can project a laser light perpendicularly to an outer surface of a cylindrical glass tube 1 to be detected. Light detectors 3, 4 are set at the side of the glass tube 1 to be opposite to the laser 2 to detect a light when the laser light is scattered in a perpendicular direction to an axial center of the glass tube 1. When no bubble streak, dust, foreign article is present at the glass tube 1 at all, the laser light projected from the laser 2 perpendicularly to the outer surface of the glass tube 1 runs straight without being detected by the light detectors 3, 4.  On the other hand, if the bubble streak is present at the side of the glass tube 1 where the laser light enters or comes out, the light is scattered in the perpendicular direction to the axial center of the glass tube 1 because of a difference of refractive indices of the bubble (air layer) and glass and detected by the light detectors 3, 4.

Title: Ignition timing control method for internal-combustion engine
Inventor: MASUI TAKATOSHI
IPC: F02P5/15
Filed: 1984-11-07
Abstract: PURPOSE:To prevent knocking from occurring during transient by previously specifying the max. allowable width of the change in angle advance in accor dance with the change in opening of a throttle valve, and by suppressing the change in angle advance at each ignition within the specified max. allowable width of the change in angle advance. CONSTITUTION:At step 42, the angle advance in ignition SA is determined from the revolving speed Ne and basic injection time Tp. At step 45, the max. allowable width AREF of the change in angle advance is determined using the difference obtained by subtracting the precedent degree of opening VTHROLD from the current one VTH of throttle valve read at this time. If the change in angle advance is over the max. allowable width of the change in angle advance, an angle advance corresponding to this max. allowable width is made at step 47 from the angle advance in precedent ignition. This will surely prevent knocking from occuring durin transient because of over-advance of the ignition angle.

Title: Drive method for piezoelectric vibrator
Inventor: YAMAZOE TOSHIHIRO
IPC: H03B5/32
Filed: 1988-09-20
Abstract: PURPOSE:To attain the application of a large input even to a vibrator with a comparatively high impedance by employing a small capacity transformer so as to form another power supply higher than a power voltage thereby operating the final stage of the circuit by the said other power supply. CONSTITUTION:An output signal from an output section 5 is boosted by a transformer 6, rectified by a diode 7 and the electric charge is stored in a capacitor 8 to obtain other power supply 9 higher in voltage than the power supply 2. Output signals from an output stage 3 control bases of output transistors(TRs) 11, 12 while one is not subject to any phase shift but the other is shifted by 180 deg. at an inverter 10. A piezoelectric vibrator 13 driven connects to collectors of the TRs 11, 12, and the power supply for the TRs 11, 12 is obtained from other power supply. The boosting transformer is not matched by a frequency component of the output signal of the output stage 3, but the transformer boosts a reference signal with the higher frequency or a signal output of a constant frequency comparatively higher among frequency division signals. Thus, as the frequency of the output signal from the output section 5 is higher, the smaller the size of the transformer is.
