Title: Acoustic sensor
Inventor: HARADA MUNEO
IPC: G10L25/00
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To avoid increasing the size and improve the detection sensitivity by laminating at least one of resonators and a wave receiver. SOLUTION: A resonating part 21 has a cantilever structure and is composed of 6 pairs of resonators 25 with rod-like parts, having lengths adjusted so as to resonate at specified frequencies. The thickness or the length of each resonator 25 is changed to set its resonance frequency to a desired value so that each resonator 25 has a natural resonance frequency. When a sound wave propagates to a wave receiver 23a in such constitution, the plate-like receiver 23a vibrates and this vibration showing the sound wave propagates to a holder 22 via a propagating part 26 to resonate the rod-like resonators of the resonation part 21 held in the holder at their respective specified frequencies one after another, thus propagating from the left to the right.  The receiver receives the sound wave propagating in a medium and gives the sound wave to the resonators resonant in their different frequencies, and at least one of these and the receiver are laminated.

Title: Pavement thickness controlling method for paving machine
Inventor: FUJITA MAKIO
IPC: E01C19/48
Filed: 1990-11-14
Abstract: PURPOSE:To make smooth finishing available for the surface of pavement by a method wherein a screed is controlled so that the difference in altitude between the position on a flatness straight dataum line at a target point positioned forward at a specified distance in the direction in which the screed travels and the position on an estimated flatness straight line becomes zero. CONSTITUTION:Paving material is laid and rolled with a screed 3 as a vehicle 1 travels. A first and a second height sensor and a gradient sensor installed on a base member 8 measure the distance to the surface of the pavement and inclination of the base member 8, and a distance sensor 19 measures the distance of travel. All the measured results are outputted to a computing unit. The computing unit calculates a flatness straight datum line out of the heights on four points on the paved surface, and calculates an estimated flatness straight line out of the height on two points nearest to the next pavement. Then extent of operation for a pivot cylinder 6 is calculated so that the cylinder can operate to make the difference between a value obtained on the straight datum line at a target point positioned forward at a specified distance in the travel direction and a value on the estimated straight line becomes zero. The calculated results are then sent to a solenoid valve, and thereby the cylinder 6 is made operable in expansion and contraction for controlling of the screed 3.

Title: Semiconductor memory
Inventor: KAKI SEIJI
IPC: H01L21/822
Filed: 1986-12-25
Abstract: PURPOSE:To prevent leakage current from flowing between groove-shaped capacitors, by forming high-concentration impurity regions which have higher concentration than a semiconductor substrate and are of the same conductivity type as the substrate on a region just under an element separation region between the groove-shaped capacitors which are formed adjacent to the element isolation region being interposed therebetween. CONSTITUTION:When high-concentration impurity regions 21 and 22 are formed respectively on a region which is disposed between groove-shaped capacitors C11 and C12 and in which an interference leakage current easily flows, that is, just under an element isolation region 12, and on a region which is as deep as bottom parts of grooves 13 and 14 where the groove-shaped capacitors C11 and C12 are formed, the interference leakage current can be effectively prevented from flowing. In this example, profile peaks in impurity concentrations are formed just under the element isolation region 12 and on regions as deep as the bottom parts of the grooves 13 and 14 where the groove-shaped capacitors C11 and C12 are formed. However, since the leakage current flows in quantity just under the element isolation region 12, the profile peak in the impurity concentration is allowed to be disposed only just under the element isolation region 12 so that the leakage current can be sufficiently suppressed.

Title: Manufacture of lead frame for semiconductor device
Inventor: SUGIMOTO HIROSHI
IPC: H01L21/56
Filed: 1993-12-08
Abstract: PURPOSE:To eliminate the removal of a dam bar after molded by preventing a lead from being deformed due to resin dry at the time of forming a dam bar made of an insulating resin. CONSTITUTION:Pneumatics is applied to a cylinder 6 with an insulating resin 4 put in through air hose 7, and the cylinder is moved with respect to a lead frame 1 and at the same time the insulating resin 4 is sprayed from dispenser nozzle by a fixed amount and coated in the predetermined position of the lead frame 1 to form a dam bar 3. The melted insulating resin 4 applied to a lead 2 shrinks when it is dried, but the lead 2 is deformed due to the shrinkage, and thus a spacer member 8 is used as a restriction means and the interval of the leads adjacent to an applied part is held by the spacer 8a, thereby preventing the deformation of leads due to the drying of the insulating resin.

Title: Spin valve sensor, magnetic head, magnetic disk drive, and forming method of these
Inventor: HARDIAL SHIN JILL
IPC: G11B5/39
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To minimize the shunting of the sensing current and to increase reading signals by replacing two cobalt layers in the AP layer to be pinned with two cobalt iron films. SOLUTION: The spin valve sensor 300 contains an AP layer to be pinned 302 disposed on an AFM pinning layer 304. The AP layer 302 to be pinned is improved by forming an AP bonding film 306 between two ferromagnetic films 308, 310 and using two films 308, 310 consisting of cobalt iron (Co90Fe10). The cobalt iron of the two films 308, 310 gives the films having low saturation coercive force, near-zero magnetostriction and high resistance. With the low saturation coercive force, when the magnetic moment in the two films 308, 310 is switched by 180 degrees by an external magnetic field, the exchange magnetic field coupling can always return then to the position to be pinned. In this case, the saturation coercive force of the two films 308, 310 is preferably half or less than half of the exchange coupling magnetic field.
