Title: High-frequency heating device
Inventor: HOTSUTA KOUICHI
IPC: F24C7/08
Filed: 1978-11-17
Abstract: PURPOSE: To prevent erroneous operation caused by taking a figure of previous indication for that of a new indication, by making such an arrangement that only when a user touched a knob of an analog value changing device, after completion of heating, it (the touching) is regarded as setting of a new figure and the indication and pickup are executed.  
     CONSTITUTION: After completion of heating operation, when a user touched a knob 9-a of an analog value changing device 4-a in an attempt to make a new setting, as a electrostatic capacity 12-a of human body enters between the knob and a gland G, a sensing amplifier 10-a generates a single pulse, and a transistor 11-a is turned on temporarily. And therefore, as a voltage of a pulse input terminal of a voltage com- parator 2-a becomes a power source voltage temporarily, a comparator generates a pulse signal, and a microcomputer 1 detects that the user touched the knob. And then, the microcomputer converted an analog value set by the knob to a digital value and makes an indication of the value to an indicating device 6 while keeping it into memory by RAM section 1W4.

Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain an easy and accurate measuring method for a piezoelectric constant at a low cost by impressing voltage in a layered measuring body and deforming and detecting the displacement of reflection light due to the deformation, with a photoelectric element. SOLUTION: A laser beam generated by a laser source 1 is introduced to the surface of a measuring body 3 fixed with a holding jig 2. The angle of the jig 2 is controlled so that the laser beam reflected on the surface of the measuring body 3 comes in the center of a photoelectric element 5. Then the element 5 is moved for a certain degree with a piezoelectric element 6 and the change in the quantity of light at that moment is measured to be a calibration value. When voltage is impressed in the measuring body with a function generator 4, the measuring body 3 is deformed and resultantly, the quantity of light on the light receiving surface of the element 5 changes. In the next, the distortion of the measuring body is obtained with using a calibration value. By dividing the distortion of the measuring body 3 with the impressed voltage, a piezoelectric constant is obtained.

Title: Manufacture of semiconductor integrated circuit device
Inventor: YOSHIURA AIMEI
IPC: H01L21/60
Filed: 1984-07-11
Abstract: PURPOSE:To form a PSG film and to prevent another separation from occurring due to a glass flow or a phosphorous treatment by eliminating an internal stress occurred on a silicide film or a high melting point metal film through introducing impurities with a heat treatment in a manner not to exist. CONSTITUTION:Impurities are introduced into a principal plane of a semiconductor region 5 of both ends of a conductive film 4 through an insulating film 3 by using the conductive film 4 as a mask for introducing impurities. As this introduction of impurities is performed by a relatively big energy with an arsenic ion at full atomic weight, a crystal damage is occurred on a molybdenum silicide film and a stress inducing another separation is generated. As an n<+> type semiconductor region 6 is formed by performing an spreading diffusion introduced after this, an internal stress occurred in the molybdenum silicide film 4B with the introduction of impurities is eliminated. This spreading diffusion, that is, a heat treatment process is performed, for instance, within the time of about 10min with the temperature of the heat treatment of about 950 deg.C.

Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent reception state by reducing cross modulation and intermodulation interference and suppression in sensitivity under a strong electric field strength of an interference wave. SOLUTION: A detection signal S3 passed through an antenna 1 and a reception section 2 is amplified by a low frequency signal amplifier circuit 6 and the amplifier signal is outputted.

In this case, the sound volume reduction by the sensitivity suppression is corrected by increasing the amplifier gain of the low frequency signal amplifier circuit 6.

Abstract: PURPOSE:To lighten a diaphragm and to attain the frequency characteristics of broad band, by changing magnetic flux passing through the diaphragm and a magneto-resistance effect element, etc. through the displacement of the diaphragm and picking up the change in the resistance value of this magneto-resistance effect element. CONSTITUTION:In applying a sound pressure to a diaphragm 1, the same is displaced to a direction that a gap G is decreased, the resistance value of magneto- resistance element 5a, 5b is decreased and the magnetic flux passing through the MR elements 5a, 5b is increased. Through the increase in the magnetic flux, the bias magnetic field by bias magnets 9a, 9b is relatively small, and while the magnetization of the MR element 5b is changed to a direction that an angle of direction between the magnetization and the current is decreased, the magnetization of the MR element 5a changes to a direction that an angle of direction between the magnetization and the current is increased. Thus, the resistance value of the MR elements 5a, 5b is changed to a direction that the both are increased, and this resistance change is picked up as a change in electric signal from electrodes 6a and 6b.

Abstract: PURPOSE:To reduce the error by selecting a current voltage conversion coefficient of a digital signal processing circuit to be approximately (1/R1'-1/Z ').e<-jw>TD and selecting a current voltage conversion coefficient of an analog signal processing circuit to be (-1/R1'). CONSTITUTION:A voltage current conversion coefficient HA of an analog signal processing circuit 1 depends on a gain 1/R1' of an adder 13. A voltage current conversion coefficient HD of a digital signal processing circuit 2 is expressed approximately to be HD=(1/R1'-1/Z').e<-jw>TD. When the desired impedance Z is synthesized, the impedance is converted into an impedance Z' by taking a delay time TD of the circuit 2 into account. The relation of R1'+R2'=R1+R2, C'.R1'.R2'=C.R1.R2 and C'.R2+TD.R2'/R1'=C.R2 is established. The synthesis is implemented with high accuracy by feeding back a signal via an analog feedback path and a digital feedback path.
