Title: D/a converting circuit
Inventor: HARA YASUNORI
IPC: H03M1/76
Filed: 1988-03-17
Abstract: PURPOSE:To reduce the input voltage dependency of the scale of an on- resistance by connecting the CMOS analog switch of a D/A converting circuit in parallel to a (p) type FET paired with an (n) type FET for a resistance and the (p) type FET of a unit cell. CONSTITUTION:In a gate array type IC common in a surface diffusion and different only in a wiring pattern, N-FET 207-212 fix a gate 12 to the lowest potential, are used as resistances 3-6 and connect serially between reference terminals 1, 2. The analog switch groups 21-26 for selecting respective connecting points as an output are constituted of n-FETs 201-206 and p-FETs 101-112. By such a constitution, since for instance, a switch 24 is constituted of the p-FETs 101, 107 and the n-FET 201, the channel width of the p-FET is substantially twice as wide as the channel width of the n-FET and the driving capability thereof is substantially equal. Consequently, the on-resistance of the CMOS analog switch is substantially constant to a switch input voltage and the input voltage dependency of settling time can be reduced.

Title: Formation of thin film transistor
Inventor: YANAI KENICHI
IPC: H01L29/78
Filed: 1986-03-24
Abstract: PURPOSE:To improve the interfacial characteristics and to prevent the short- circuit defect generating on the titled transistor by a method wherein, in an insulated gate type thin film transistor provided with a hydrogenated amorphous silicon active layer, a gate insulating film and a semiconductor film having no pin-holes are continuously formed by performing a plasma CVD (chemical vapor deposition) method or a photo- CVD method. CONSTITUTION:A gate electrode 2 is formed on a glass substrate 1. Subsequently, a silicon nitride SiN film 3 is formed. In the beginning of the formation of the SiN film 3, the first gate insulating film 3 is deposited using the CVD device of electron beam excitation. The accumulated potential on the film surface due to electron charge is not increased on a pin-hole part 29 due to electron charge even when pin-holes 29 are generated while the gate insulating film is being deposited. As a result, electron streams 24,... coming from an emitter 21 are concentrated at the pin-holes 29, the dissociation speed of raw gas is increased, and a film is grown locally. Then, a silicon nitride film 4, which becomes the second gate insulating film, is formed by performing a CVD method using optical excitation or a CVD method of plasma excitation by high frequency electric field.

Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a switching power apparatus which facilitates the overcurrent protection by utilizing the forward voltage blocking time of the saturable reactor in a magnetic amplifier circuit. SOLUTION: A DC voltage surface 1 is switched by a transformer 5 and a switching device 4. If the output current of a quasi-regulated power supply E which is outputted from the 2nd secondary winding 521 of the transformer 5 exceeds a rotated current, the control current Ic of a magnetic amplifier control unit 6 is turned to zero, and a saturable reactor ML can not be controlled, a voltage blocking time becomes zero and a transistor Q can not be turned on. Further, a 2nd photocoupler P2 is continuously in an OFF-state, a capacitor Cc is continuously in a charged state and a voltage between both the terminals of the capacitor Cc is elevated to a Zener voltage. Therefore, if the voltage of the capacitor Cc exceeds the Zener voltage, a driving control unit 2 decides that the quasi-regulated power supply E2 is in an overcurrent state and discontinuous the power supply generation.

Abstract: PURPOSE:To enhance relative positional accuracy between a 1st original plate and a 2nd original plate by holding a 2nd frame for holding the 2nd original plate through a 2nd sliding mechanism to a 1st frame for holding the 1st original plate. CONSTITUTION:When a motor 40 on the supporting table 17a of the 1st frame 17 is rotated so as to rotate a screw shaft 39 in a direction opposite to the screw shaft 29, a screw follower 41 is moved along the screw shaft 39, and the 2nd frame 21 fixed on the screw follower 41 is moved in a direction shown by an arrow B. Thus, the original plate 20 is also moved to a position where it can nearly come into contact with a base material 15, and the original plates 16 and 20 which are positioned on both sides of the base material 15 are moved to a closing position. Then, the frame 21 holding the original plate 20 is held by the supporting table 17a which is the part of the frame 17 for holding the original plate 16 through the 2nd sliding mechanism 22, so that the relative positional accuracy between the original plates 16 and 20 which are brought into tight contact with both sides of the base material 15 is fixed only by the accuracy of the mechanism 22, and it is not influenced by the 1st sliding mechanism 19 for holding the frame 17. Thus, the deviation between the original plates 16 and 20 can be reduced.

Title: Production of compositionally gradient body of nitride-base ceramic and metal, the body for substrate and the body for structural material
Inventor: TOYODA SEIJI
IPC: C04B35/58
Filed: 1994-03-09
Abstract: PURPOSE:To produce a compositionally-gradient body of ceramic and metal with improved productivity. CONSTITUTION:Aluminum nitride AlN powder, W powder and alcohol are prepared, and the AlN powder and W powder are agitated and mixed in the alcohol to form a suspension. The suspension is cast in a mold, and the cast is degreased and burned to produce the compositionally-gradient body of ceramic and metal. The compositional ratio of the nitride-base ceramic to the metal is continuously changed from 1:0 to 0:1. As a result, a nitride-base ceramic body need not be formed for the purpose, a metallic paste need not be prepared, and hence the production process is simplified. Further, since the settling velocity of the suspension is higher than that of an unsolidified green sheet, the production time is shortened, and productivity is improved.

Abstract: PURPOSE:To measure minute moving quantity with high precision by calculating a variation of the intervals of the fringes taking place on a display part when a photoelectric transducer line and an object to be measured are moved along an optical axis with reference to a transmission type interference fringes generating element. CONSTITUTION:When the photoelectric transducer line 70 and the object 80 to be measured are moved along an optical axial direction with reference to the transmission type interference fringes generating element 60, the intervals of the interference fringes formed on the line 70 are also changed.
