Patent JP-H06291256-A (JP)
Title: Semiconductor integrated circuit
Inventor: NAKANO MASAKO
IPC: H01L27/04
Filed: 1993-04-01
Abstract: PURPOSE:To prevent the area used to supply a power source and ground from increasing by supplying the power source and the ground from other points than both edges of a primitive cell row through a power source or a ground pass to positions on the primitive cell which a second metal layer can pass. CONSTITUTION:The longitudinal direction is a second metal layer wiring direction. Power to a functional block is supplied by power sources Vcc1 and 6 and ground GND1-6, and power sources 2-5, power sources Vcc7-10 and ground GND2-5, and ground GND7-9 which are a second metal layer pass. A wiring region A1 of the wiring block mainly comprises a first metal layer, and an element region B1 mainly comprises primitive cells a-m. At a position where the second metal layer pass on the cells a-m is passable, power and ground are supplied to inside the cells a-m from points other than both edges of the cell row a-m through the power source Vcc and the ground GND pass. This enables a block area to be made small and a shield effect to be obtained.

Title: Engine throttle valve control device
Inventor: KOBAYASHI HIDEO
IPC: F02D11/08
Filed: 1982-05-07
Abstract: PURPOSE:To increase a positional allowance of a negative pressure take-out opening, by arranging such that an atmospheric chamber and a negative pressure chamber which are provided to a negative pressure actuator and adapted to function concurrently as a dashpot and a throttle opener operable by a negative pressure in an intake air tube are communicated via orifices with an atmosphere respectively. CONSTITUTION:An operating lever 12 of a negative pressure actuator B abuts with one end of an interlocking lever 6, the latter lever 6 being connected with a throttle valve 3 provided in an intake passage 1 of an engine. In the time of deceleration, release of an operating wire causes a return spring (not shown) to pivot in the closing direction, while simultaneously raising the operating lever upwardly via the interlocking lever 6. At this time, contraction of the atmospheric chamber 9 and expansion of the negative pressure chamber 10 which take place as a result of deformation of a diaphragm 11 are decelerated through orifices to provide a function as a dashpot. Upon the throttle valve 3 being closed to a preset opening amount, a resultant increase of intake air in its negative pressure entering into the negative pressure chamber can render the diaphragm 11 inoperative and retain the throttle valve 3 as opened with a small amount. Thereby, the cushioning effect does not depend upon an intake air take-out position.

Title: Parity processing system
Inventor: SAKAI TAKAHIKO
IPC: G06F11/10
Filed: 1983-04-30
Abstract: PURPOSE:To check the propriety of a shift circuit by using the output of the 2nd shift circuit as an output parity data in place of the output of a parity generating circuit when the shift number is equal to an integer multiple of (n) bits. CONSTITUTION:The m-bit output of a shift circuit 21 is led to a selecting circuit 22 via a signal line L11. The circuit 22 outputs the m-bit output of the circuit 21 to a signal line L12 as the parity data to the N-bit output of a shift circuit 11 in case the shift number designated via a signal line L4 is equal to an integer multiple of (n). The signal of the line L12 is estimated from the input parity data and the shift number. Therefore, a parity check is carried out from the N-bit output data outputted from the circuit 11 and the m-bit parity data outputted from the circuit 22 in case the shift number designated via the line L4 is equal to an integer multiple of (n). Thus the priority is checked for the circuit 11.

Title: Core structure for molding form
Inventor: SAKUMA MASAKATSU
IPC: B28B7/30
Filed: 1995-03-31
Abstract: PURPOSE: To effectively prevent the buckling of a core, the bending deformation, the fusiform deformation or the plastic deformation due to an axial compression force by axially retractably setting the core in cooperation with the temperature rise of the core. CONSTITUTION: Since a curing chamber becomes a considerably high temperature due to vapor in the curing, cores 13 made of long and tapered rubber cylinders tend to abruptly elongate. In this case, the cores 13 are brought at the ends 13b into contact with one another, but the base ends 13a are axially slidably supported by core support cylinders 12. Thus, the cores 13 can smoothly elongate in the direction separating from sidewalls 10 while sliding at the base end side in the cylinders 12. Accordingly, the cores 13 are not received by any axial compression force.

Title: Manufacture of semiconductor element
Inventor: HARADA YUSUKE
IPC: H01L23/48
Filed: 1989-03-30
Abstract: PURPOSE:To prevent an encroachment phenomenon of a W film from being caused at an interface between Si of a substrate and an insulating film by a method wherein a thin insulating film is formed on a side face of a contact hole in such a way that it is extended to the bottom of a recessed part formed in a substrate part by an overetching operation. CONSTITUTION:When a contact hole 24 is formed in one part of an interlayer insulating film 23, it is overetched because of a uniformity inside a face of a substrate at an etching operation; as a result, a substrate part at the bottom of the contact hole 24 is formed in a recessed shape. Then, a thin insulating film 25 is formed; its whole face is etched by RIE; then, an interface between the interlayer insulating film 23 and Si of the substrate is covered with the insulating film 25; this film is left on a side face of the contact hole 24 in such a way that it is extended to the bottom of the recessed part produced in the substrate 21 when the contact hole has been formed. Accordingly, when the contact hole 24 is filled with a W film 26 by selective WCVD, the exposed interface between the insulating film and the Si of the substrate is covered immediately with the W film 26 which has been grown from the bottom, and does not come into contact with WF6 gas at the selective WCVD for a long time, Thereby, an encroachment phenomenon of the W film is not caused at the interface.

Filed: 1990-03-28
Abstract: PURPOSE:To replace data between shift registers without passing through a CPU and to calculate a high speed correction pattern and correction position by providing a bus for data exchange, a driver outputting the data of the shift register to the bus and a selector. CONSTITUTION:A shift register in a circuit 1a composed of a shift register, a driver and a selector latches the data of an 8-bit data line 120 at the rise of a shift register control signal 3a. A driver 8 gives an output to a bus 4a while a driver selector control signal 2a asserts the data outputted to the data line 102. When the control signal 2a is asserted, the selector outputs the data of a bus 4b to the data line 120 and outputs the data of the data line 104 in negating. Moreover, circuits 1b-l each composed of a shift register, a driver and a selector are constituted similarly to 1a. Since the data is exchanged without passing through a CPU, high speed data exchange is implemented.

Abstract: PROBLEM TO BE SOLVED: To enable magnetoresistive element and head to have a large MR ratio by successively laminating a nonmagnetic high-resistance layer, a first ferromagnetic layer, a first nonmagnetic layer, a second ferromagnetic layer and an antiferromagnetic layer. SOLUTION: The second ferromagnetic layer 5 receives alternating bias magnetic fields from the antiferromagnetic layer and the magnetization direction is fixed in one direction. On the other hand, since the first ferromagnetic layer 3 formed via the nonmagnetic layer 4 freely changes the magnetization direction according to the magnetic fields from outside, the relative angle of the first ferromagnetic layer 3 and the second ferromagnetic layer 5 changes and electric resistance (magnetic reluctance) changes. Current flows between the first ferromagnetic layer 3 and the antiferromagnetic layer 7 and if the antiferromagnetic layer 8 is formed of suitable material, the smoothness of an atom level is embodied at the boundary S1 between the antiferromagnetic layer 8 and the first ferromagnetic layer 3 and the MR ratio increases.  Al2O3, AlN, SiO2, etc., and used as the material of the antiferromagnetic layer 8 and the film thickness thereof is preferably specified between 0.4 and 20 nm.
