Abstract: PURPOSE:To obtain a high reliable device which can operate stably at a high speed, by forming a vertical NPN transistor and FET in each separated N island on a P-type substrate, a triple diffused vertical transistor in each P well in the islands, and an FET in each P well. CONSTITUTION:On the P-type Si substrate 1 in which P<+> layer are formed between the spaced N<+> buried layers 2 and on the specific N<+> layers 2, the N<-> epitaxial layer 4 is overlapped. Using the oxide film 13 as a mask, the P<+> layer 7b and P<-> layers 8a, 9a are formed so as to oppose the buried layers. The N layers 14 which are formed by implanting ions into the P<-> layers 9a are pushed in, in order to form the N<+> layers 16-20 in the separation layers 7, P wells 8, 9, and N<-> islands 4-6. Next, the P<+> channel stoppers 12, base taking-out layers 21 of the vertical NPN elements Q1, emitter and collector taking-out layers 22, 23 of the triple diffused PNP elements Q1, emitter and collector taking-out layers 22, 23 of the triple diffused PNP element Q2, and source and drain 24, 25 of the FETs Q4 are formed at the same time, and electrodes are mounted to finish the device. In this way, the triple diffused vertical elements Q1 and FETs having a uniform gate threshold voltage can be formed on a chip in the reduced number of processes.

Title: Contact combustion type gas detector
Inventor: TANAKA TETSUO
IPC: G01N27/16
Filed: 1978-09-27
Abstract: PURPOSE: To equalize the heat dissipating coefficient of resistors in a contact combustion type gas detector and eliminate the drift thereof due to the voltage variation by equalizing the construction, size, resistance and surface color of a compensating resistor to those of an active resistor.  
     CONSTITUTION: This contact combustion type gas detector contains an active resistor fabricated by adhereing refractory powder such as alumina onto fine platinum coil and coating the surface thereof by catalytic material such as vanadium oxide, and an inactive or compensating resistor not coated with the catalytic material thereon in a bridge configuration. The resistor coated with the catalytic material generally exhibits black or brown black on the surface, while the resistor not coated with the catalystic material generally exhibits white or the like. Since the heat dissipating coefficients of both the resistors are compared so that the heat dissipating loss of the black resistor is abruptly increased at higher temperature, noncatalytic pigment is coated on the compensating resistor to equalize the surface colors therebetween.

Abstract: PURPOSE:To make the quantity of step of a mover smaller than the interval between the nodes of standing waves and the quantity of shifting of nodes of standing waves, in an ultrasonic motor for driving a mover by steps. CONSTITUTION:An ultrasonic wave oscillating circuit 107 generates progressive waves for rotating a mover 112 or standing waves for stopping it. A changeover circuit 108 controls the operation of inputting the output signal of the ultrasonic wave oscillation generating circuit 107 and outputting output pulses to a piezoelectric oscillator driving circuit 109. Ultrasonic oscillation is generated in an oscillator 111 which has a plurality of comb-toothed projections. The mover 112 has unequal parts, and the number of unequal parts is larger than the number of nodes at standing wave oscillation. The mover 112 performs operation such as rotation, stoppage, etc. The mover stops in the position where the force is balanced, by the position of the unequal part of itself, the position of the node of the standing wave, and the position of the projection of the oscillator, by changing progressive waves and standing waves over to each other in proper condition. That is, the step angle of the mover can be made smaller than the interval between the nodes of the standing waves or the quantity of shifting of the nodes of the standing waves.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To balance the distribution of the magnetic flux of a rotary electric machine and to reduce unbalanced magnetic attraction force, by adjusting the number of coil windings of the opposing coil windings of a stator. SOLUTION: The number of coil windings that pass a slot (x) for balancing the flux ϕx being induced from the coil winding passing through the arbitrary slot (x) of a rotary electric machine, and the flux passing through an arbitrary slot, is given by the expression. In this expression, β, e, αx, p, and n0 represent the coil winding coefficient, the eccentricity, the angle formed by the center line of the slot x and eccentricity direction, the number of poles of the rotary machine, and the number of coil windings at the slot (x) without eccentricity, respectively. Therefore, the eccentricity is verified in the rotary electric machine before each coil winding of opposing coil winding is adjusted, and the flux being induced from each coil winding can be balanced, thus reducing unbalanced magnetic suction force and obtaining the rotary electric machine with low vibration and noise.
