Title: Schmitt trigger circuit
Inventor: MOTOYOSHI HIROTO
IPC: H03K3/0233
Filed: 1978-10-03
Abstract: PURPOSE:To establish the circuit providing the means achieved by the parameters two or more independently for the setting of the threshold voltage and the hysteresis width. CONSTITUTION:When the input signal 28 is not fed between the input terminals 26 and 27 of transistors Tr21,22 constituting the differenteal amplifier, since Tr21 is in saturation and Tr22 is non-conductive, the first constant current source 100 is interrupted and the second constant current source 200 is conductive to flow the constant current I2 to the resistor 31. Accordingly, the positive threshold voltage VT+ is R31.I2. Next, when the voltage fed to the input terminals 26 and 27 is a value more than the said VT+, Tr21 is interrupted and Tr22 is in saturation. The first constant current source 100 is conductive and the second constant current source 200 is interrupted to flow the constant current I1 to the resistor 29. Accordingly, the negative threshold voltage VT- is -R29.I1.

Title: Semiconductor radiation detecting element
Inventor: WADA TAKAO
IPC: H01L31/115
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To perform a precise detection without being influenced by the temperature fluctuation of a detecting element by detecting radiation dose on the basis of the ratio of resistance values of a plurality of semiconductors having the same temperature dependency of resistance value change ratio and differed in thickness. SOLUTION: When a radiation is absorbed, a fixed positive charge of a quantity according to the radiation total dose is generated in an insulating layer 12 and an insulating film 14. This fixed positive charge increases the resistance values of the parts contact with the insulating layer 12 and the insulating film 14 in p-type Si layers 13a, 13b. The respective resistance value change ratios of the p-type Si layers 13a, 13b are differed depending on thickness. The output value of an electrode 15b in which the voltage applied to an electrode 15a is partially divided by the p-type Si layers 13a, 13b is detected according to the difference in resistance value change ratio between the p-type Si layers 13a, 13b, whereby the radiation total dose can be measured.  Since the p-type Si layers 13a, 13b of this detecting element can be formed in the same manufacturing process, a precise detection can be performed with being hardly influenced by the error by temperature fluctuation of the detecting element itself.

Title: Driving force distribution switching type four-wheel drive automobile
Inventor: KAWANO ATSUHIRO
IPC: B60K17/348
Filed: 1990-05-10
Abstract: PURPOSE:To prevent the generation of a spin so as to improve the travel limit by detecting yaw angle acceleration, and performing the specified driving force distribution when the detected yaw angle acceleration is less than the specified threshold value, whereas increasing the driving force distribution on the front wheel side when the yaw angle acceleration is more than the threshold value. CONSTITUTION:A steering angle theta from a steering sensor 30, lateral acceleration G1, G2 from a front and a rear lateral acceleration sensors 34A, 34B, and the detection signals of a longitudinal acceleration sensor 36 and the like are inputted into a controller 48. The yaw angle acceleration computing part 48a of the controller 48 computes yaw angle acceleration gamma' on the basis of the lateral acceleration G1, G2, and a comparing/judging part 48b compares the computed yaw angle acceleration gamma' with the threshold value gamma'0. At the time of gamma'<gamma'0, the torque distribution of front-rear wheels is performed by the specified driving force distribution. At the time of gamma' > gamma'0, however, an output part 48c controls a multiple disc clutch 28 through a pressure control valve 56 so as to increase distribution on the front wheel side. The generation of a spin can be thus prevented positively.
