Title: Hysteresis circuit
Inventor: YAMADA TAKAAKI
IPC: H03K5/08
Filed: 1982-04-15
Abstract: PURPOSE:To exclude the effect of power supply drift out of the input/output voltage transmission characteristics, by providing transistors to which the output signal of a gate circuit is supplied in parallel to the input transistor circuit of the gate circuit. CONSTITUTION:When the voltage supplied to a terminal 1 is set at a low level, transistors TR11 and 12 and turned off. Then a joint P3 of both TRs has a high impedance, and therefore the voltage V'OUT is set at a high level. This voltage V'OUT varies in accordance with increment of the input voltage Vin. When the output voltage VOUT exceeds the voltage V'OUT, the characteristics of the V'OUT change to those obtained when a TR15 is turned on from those obtained when the TR15 is turned off. When the TR15 is on, the positive feedback is applied to the input side via an inverter 14 and the TR15. Thus the TR11 is kept off and TR12 kept on respectively. The input voltage does not depend on the power supply voltage since the working of the TR15 does not depend on the power supply voltage and the circuit has no constant current source 13.

IPC: H01J37/248
Filed: 1988-03-18
Abstract: PURPOSE:To realize a low cost and a long service life, and to reduce troubles, by applying the output signal which is a triangular wave output cut off the DC component therefrom by a capacitor and added with a DC bias voltage, to the electrode of a scanning deflector. CONSTITUTION:Between the other side terminal of a capacitor 5 and an output terminal 6, a DC bias power source 8 is connected through a resistance 7 with the resistance of about 2 MOMEGA. The DC bias power source 8 is made to add a DC bias to remove the neutral particles from the ion beams generated and mass-separated from an ion source, to a triangular wave voltage passing through the capacitor 5. The high voltage DC voltage to be used is enough to be only one and a voltage necessary to the triangular wave. And, the plate loss of a triode 1 and the consumption power of a resistance 2 can be reduced. Further more, since almost little current flows to the resistance 7, a high resistance can be used there, and a small current power source can be used to the DC bias power source 8.

Title: Amorphous silicon carbide film and photovoltaic element using the same
Inventor: SHIMA MASAKI
IPC: H01L31/06
Filed: 1995-03-23
Abstract: PURPOSE: To minimize the defect density in a film by maintaining the specific relations between the optical band gap, hydrogen amount and carbon amount in the film. CONSTITUTION: An optical band gap width Eg (eV) bears the relations between the hydrogen amount CH(at.%) and carbon amount CC(at.%) as shown by the following equality i.e., Eg=a+bCH/100+cCc/100. Besides, a, b, c shall respectively meet the following inequalities i.e., 1.54<=a<=1.60, 0.55<=b<=0.65 and -0.65<=c<=-0.55. Furthermore, the defect density (Na) in a α-SiC film, when the optical band gap width is within the range of 1.67-1.71eV, is almost constant in the region of hydrogen amount within the range of 10-30at.%, but in the region of hydrogen amount exceeding about 30at.%, said defect density (Na) is rapidly increased. On the other hand, when the hydrogen amount is almost constant, the more the carbon amount, the narrower the optical band gap width.  Accordingly, if the hydrogen amount is in the region where it is within the range of 10-30at.%, the defect density in the film can be minimized.
