Title: Method for sensing positioning mark in electron-beam lithography
Inventor: ASAI SHIYOUJIROU
IPC: H01L21/027
Filed: 1979-03-12
Abstract: PURPOSE:To determin the position of a positioning mark highly accurately, by performing electron-beam scanning along the paths crossing at a mark from the two different points, and sensing the scanning speed of the beam by using the difference in time lengths from the beginning of the scanning and to sensing of the mark. CONSTITUTION:An electron beam is scanned along a path 301 from a point X0- X1, and the beam is turned on and off during the scanning. Scattering of electrons, when the beam crosses a target 302, is sensed; and the time, when the sensed signal crosses a threshold level 303, is sensed. The period from the beginning of the beam scanning to the time at which the threshold crossing is sensed is counted N1-N4 by a counter which is connected to an oscillator with a specified frequency. Then, scanning from a point X0' which is well separated from the point X0 is counted at the same speed to obtain the values N1'-N4'. The scanning speed C is obtained by dividing the distance (X0-X0') by the difference in the arithmetic means of the counted values. The position of the mark can be obtained by X0+C(N1+... +N4)/4 very accurately, and is not affected by the scanning speed of the beam.

Title: Semiconductor pressure sensor
Inventor: SAWAKI HISASHI
IPC: H01L29/84
Filed: 1983-02-22
Abstract: PURPOSE:To enlarge the degree of freedom of the arrangement of gauge resistors and increase the measuring accuracy by reducing the dispersion by a method wherein the longitudinal direction of the gauge resistor is composed of two pairs of diffused resistors rectangularly intersected with each other, and the outer pressure is calculated out by detecting the amount of changes of the four gauge resistors in a Wheatstone bridge circuit. CONSTITUTION:When the surface rientation of an Si substrate is decided as the plane (111), and the longitudinal direction of the gauge resistor is taken to the rectangularly intersected direction such as the axis <-110> and the axis <11-2>, the gauge resistors 21' and 23' of the axis <-110> do not receive the stress of the X axis (sigma x=0) but receive only the stress of the Y axis (sigma Y), and accordingly their values vary to plug. While, the gauge resistors 22' and 24' of the axis <11-2> do not receive the stress of the Y axis (sigma y=0) but receive only the stress of the X axis (sigmax), resulting in variation to minus. The titled device of a high accuracy can be obtained by detecting the amount of variation by the Wheatstone bridge circuit and then converting it into pressure.

Filed: 1986-02-12
Abstract: PURPOSE:To secure the quietness of a wiper at the time of low speed or stopping by providing a motor speed controlling means for driving said wiper at a set low speed of driving speed or less when the vehicle speed is above a defined value. CONSTITUTION:When a vehicle speed above a defined value is detected by a vehicle speed sensor 13, the output of a controller 12 becomes high and the fixed contact 11c of a changeover switch 11 is grounded, to make a wiper device carry out an ordinary action. Then, when a vehicle speed less than the defined value is detected, the fixed contact 11c is intermittently grounded due to a pulse width control. As a result, a current is intermittently fed to the motor, which is rotated at a low speed. Thereby, the driving speed of the wiper becomes low, securing a desired quietness.

IPC: C10L1/08
Filed: 1990-02-09
Abstract: PURPOSE:To obtain fuel oil for a diesel engine which is improved in ignitability and generates an exhaust gas containing an extremely small amount of toxic substances by incorporating dimethyl acetal as an active ingredient. CONSTITUTION:Fuel oil for a diesel engine is obtained by incorporating dimethyl acetal as an active ingredient. As compared with conventional mineral oil fuel, this fuel oil produces an extremely small amount of graphite, generates an exhaust gas that contains a very little NOx and has high ignitability and thermal efficiency. Due to these merits, this fuel oil can be used advantageously as diesel engine oil. Further, due to its good compatibility with mineral oil, this fuel oil can be mixed with mineral oil to obtain a fuel oil composition. In this case, the amount of dimethyl acetal may account for 50 to 100vol% of the total amount of the fuel oil and the mineral oil. This fuel oil exhibits good performance when employed for a collision diffusion layer air-charging combustion type diesel engine.
