Title: Magnetoresistance effect element
Inventor: OKABE HIROTAKA
IPC: H01L43/08
Filed: 1988-08-31
Abstract: PURPOSE:To detect an external magnetic field with high sensitivity by electrically connecting plural ferromagnetic substances having magnetoresistance effect to array them in parallel, allowing current to flow into the ferromagnetic substances and their adjacent current routes to generate bias magnetic fields in parallel in the same direction. CONSTITUTION:An interdigital pattern with 20mm width is constituted on a base 3 and magnetoresistance effect (MR) elements 1 are arrayed in parallel and electrically connected through adjacent conductor parts 2. An MR element part 1 consisting of an MR film 10, a magnetic separation film 11 and a soft film 12 is formed on the base 3. When the conductor part 2 is connected to a current source 8 and a sense current 6 is allowed to flow into the MR element part 1 in the same direction, magnetic coupling between the MR film 10 and the soft film 12 is generated and bias magnetic fields are impressed to the MR film 10. When an external magnetic field 9 is impressed to the MR element part 1, the magnetizing direction of the MR film 10 is rotated, resistance is changed, voltage applied to both the ends of the MR element 1 is changed, and the voltage change is detected by an amplifier 8. Thus, the external magnetic field can be detected with high sensitivity.

Title: Amplitude detection device for measuring dielectric constant
Inventor: TAKE MASAFUMI
IPC: G01R19/25
Filed: 1990-08-21
Abstract: PURPOSE:To enable change in holding value due to leak current etc. to be reduced and achieve a highly accurate amplitude detection by holding a peak of an input signal and performing its A/D conversion readily. CONSTITUTION:An upper peak hold PH circuit 4 holds peak of an upper side of signal which is transmitted by a sinusoidal wave generator 1 through a sample 2 and feeds that value into an upper A/D converter CV5. This CV5 receives SP from a SP generation circuit 6 which a signal at the generator 1 transmits when peak hold is completed and converts the maximum value of hold within the circuit 4 into digital value. A lower peak detection system which is in a same configuration as this upper peak detection system performs A/D conversion with a value where a minimum value of input sinusoidal wave is inverted with the same operation as in the upper side by using an inversion amplifier 3. Then, both the maximum and minimum digital values are read by a CPU 7, which calculates a value of the input sinusoidal wave. The peak hold of input signal can be readily converted into digital values, thus enabling influence of leak current to be reduced.

Title: Safety device in garbage collection vehicle
Inventor: IKEDA TATSUO
IPC: B65F3/20
Filed: 1987-09-03
Abstract: PURPOSE:To enhance the safety by providing a charge circuit and a discharge circuit in a drive circuit for a push-in member actuator, and by using an interlock type switch as a loading switch so that one of them is turned off whenever the other is turned off. CONSTITUTION:When a loading switch SW is pushed, a switch member S1 associating with the loading switch SW energizes a charge circuit 18 but deenergizes a discharge circuit 19. Thus, a capacitor C is charged while a loading instruction relay coil R3 is driven to energize a loading instruction circuit 13. When the loading switch SW is released, the drive of the loading relay coil R3 is stopped. At this time, even though the loading switch would be left to be pushed, charge current is cut off after a predetermined time which is determined by the capacitor C and the relay coil R3 elapses, and accordingly, the drive of the loading instruction relay coil R3 is stopped. The capacitor C discharges at once when the loading switch SW is released. Thus it is possible to enhance the safety.

Title: Structure of solid-state image pickup device and manufacture thereof
Inventor: JIN SHOBU SHIN
IPC: H01L31/0216
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To obtain a solid-state image pickup device, suited for enhancing the sensitivity by placing protrudent lines which has a fixed width and extends in one direction at a position facing portions of vertical charge transfer regions to improve the light condensing efficiency of microlenses. SOLUTION: A black and white solid-state image pickup device has a passivation insulating film 35 on which a first flat layer 36 is formed. On the first layer 36 a color filter layer 37 allowing light of only specified wavelength to pass to photodiode regions is formed. A second flat layer 38 is formed on the entire surface to form microlenses 41 between protrudent lines 39 with fixed spacings. The microlens 41 has an elliptic shape, partly extending in its minor axis direction to the protrudent line 39, and its radius of curvature increases to make the focal length of a light incident on the photodiode region 32 coincide with the major and minor axes of the lens 41. Hence the radii of curvature in the major and minor axes of the lenses are approximaterly equal to thereby avoid the optical loss, improving the sensitivity and resolution of the solid-state image pickup element.
