Title: Inverter circuit device
Inventor: TANAKA MASAJI
IPC: H03K19/0948
Filed: 1990-03-08
Abstract: PURPOSE:To reduce power consumption by connecting input terminals of 2nd and 3rd inverters(INV) to the output terminal of a 1st inverter, and connecting output terminals of the 2nd and 3rd INV to the gate of a complementary transistor(TR). CONSTITUTION:When an input voltage level changes from an L to an H and the output of an INV 1 passes through the switching level of an INV 2, the output level of the INV 2 changes from an L to an H level. A P-channel TR P1 of an output stage changes from ON to OFF and a final output goes from an H level to a high impedance and no through-current flows to the TRs P1, N1. When the output of the INV 1 passes a time reaching the switching level of an INV 3, the output level of the INV 3 changes from an L to an H level, the TR N1 is turned on and a final output goes to an L level. When the input level changes from an H to an L, the final output changes to H   high impedance   L. Since the TRs P1, N1 are not simultaneously turned on, no through- current flows to the output stage and the power consumption is reduced.

Title: Semiconductor integrated circuit
Inventor: ITOU KIYOO
IPC: G11C11/407
Filed: 1981-04-17
Abstract: PURPOSE:To obtain a high density semiconductor memory as a whole, by increasing the size of the element in a circuit responding to a signal whose amplitude is large so as to increase the withstanding voltage and to decrease the size of the element in a circuit responding to the output signal of the former circuit. CONSTITUTION:On a P type semiconductor substrate 10, the first circuit 40 comprising a peripheral circuit directly connected to a memory array and the second circuit 50 comprising an indirect peripheral circuit which controls the first circuit are formed. Since the area of said second circuit 50 is only about 10% of the entire area of the chip, an MOS element which has an especially small size is not used. Instead the MOS element of the first element 40 which occupies the large area is reduced. That is, the thickness of a gate oxide film tox1 of the N type MOS element Qm constituting the circuit 40 is made thinner than the thickness of a gate oxide film tox2 of the N type MOS element Qp forming the circuit 50. A high voltage VCC is applied to a drain Dp of the element Qp from a substrate voltage generating circuit 20 and a low voltage VDP is applied to a drain Dm of the element Qm from an internal power source voltage generating circuit 30.

Title: Valve timing controller for internal combustion engine
Inventor: MAKINO HIRONOBU
IPC: F02D41/04
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To control valve timing with an appropriate response speed by absorbing piece-to-piece variation of internal combustion engine, variable valve timing mechanism, and oil control valve. SOLUTION: According to the operating condition of an engine 1, open-close timing of an intake valve 17 is changed by a variable valve timing mechanism 60. A response speed of the variable valve timing mechanism 60 is controlled, based on a control duty ratio of an oil control valve 63. The control duty ratio is corrected by learning according to whether the response speed of the variable valve timing mechanism is faster or slower than the expected response speed.

IPC: H01M4/80
Filed: 1985-03-20
Abstract: PURPOSE:To restrain the nickel corrosion during the impregnation procedure of active materials, so as to prevent the decrease of mechanical strength of the pole plates and to make, free of occurrence, variation or decrease of the utility factor of active materials, by producing passive membrane composed of very thin oxide layers uniformly on the surface of sintered nickel plates. CONSTITUTION:Nickel powder is kneaded with organic water-soluble macromolecule and water to produce nickel slurry, and after the slurry is applied to porous electro- collectors and dried, the nickel powder is sintered in an atmosphere containing more than ten times equivalent weight of water vapor for carbon content contained in the nickel to produce sintered nickel plates. Further, the sintered nickel plates are heat-treated in an atmosphere containing oxygen at 160-300 deg.C, and the passive membrane composed of nickel oxide layers is produced on the surface of the sintered nickel plates. By this, passive membrane composed of very thin uniform oxide layers can be produced on the surface of the sintered nickel plates, and so the nickel corrosion during the impregnation procedure of active materials can be restrained, and thus the decrease of mechanical strength of pole plates can be prevented, and the pole plates having no or little decrease of utility factor of active materials can be obtained.

IPC: F42D1/08
Filed: 1989-03-10
Abstract: PURPOSE:To improve substantially a work efficiency by a method wherein a pressure from an exploded hole is received and a tension bolt is slid toward a ground surface with respect to a guide pipe. CONSTITUTION:An adjusting nut 8 of a slip main body 21 is positioned at an extreme end of a tension bolt 7 and a guide pipe 1 is lifted up vertically, resulting in that a slip part 3 closes in such a way as it is positioned near an axis of the slip main body and under this condition, the slip main body can be inserted into an exploded hole in an axial direction through an opening on the ground surface. Then, an adjusting nut is rotated to cause the slip part to be moved away from an axis of the slip main body, engaged with an inner wall of the exploded hole and fixed there. As a cap 9 receives a pressure of gas or sludge injected out of the exposition hole, a force for pulling up the tension bolt is applied and the slip part may operate to open. It is strongly engaged with the inner wall of the exploded hole to increase a fixing force. The cap positively prevent the sludge from being ejected via the explosion hole. Thus, a simple and easy operation can be assured.

Abstract: PURPOSE:To improve the deposition of fine particles of an org. polymer and to form a plating film contg. uniformly dispersed fine particles by adding a water soluble arom. compd. as well as the fine particles to an acidic zinc electroplating bath. CONSTITUTION:An acidic zinc electroplating bath contg. fine particles of an org. polymer is prepd., a water soluble arom. compd. is added to the bath by about 0.1-10 g/l and a steel sheet as the cathode is electroplated with the resulting bath to form a zinc plating film contg. dispersed fine particles of the org. polymer. Since the water soluble arom. compd. makes the surface of a plating film finely rugged and the fine particles are embedded in the recesses, the exfoliation of the fine particles from the surface of the plating film is hardly caused even by stirring the plating bath and the deposition of the fine particles in the plating film is improved.
