Title: Throttle valve opening detector for vehicles
Inventor: MINAGAWA KAZUJI
IPC: F02D9/00
Filed: 1985-06-05
Abstract: PURPOSE:To secure a highly accurate sensor output over a long period of time, by setting a positional slip direction of a throttle shaft and a turning force transmission direction inside a connecting device connecting a throttle opening sensor and the throttle shaft so as to be crossed within the specified angle range. CONSTITUTION:When a bearing member 17 supporting a throttle shaft 16 is worn out due to long use and thereby a clearance is produced there, a throttle valve body 18 receives large suction pressure at the time of idling, whereby the shaft 16 causes a positional slip in a suction pressure acting direction. With this positional slip, a projection part 20a of a projection member 20 at the side of the throttle shaft of a connecting device 25 also moves in the same direction, and thereby a side face of the projection part 20a slides with a side face 24 of a projection member 12 at the sensor side of the connecting member 25, but the said member 12 receive not turning force. That is to say, since the said positional slip direction the direction where the turning force is transmitted by contact between both projection members 20 and 12 are crossed as far as 90 deg. with each other, the said projection member 12 is in no case rotated, thus a wrong signal out of a throttle opening sensor 1 is prevented from occurring.

Title: Liquid crystal display device and its production
Inventor: KONO HIROAKI
IPC: G02F1/1337
Filed: 1995-05-22
Abstract: PURPOSE:To obtain such a display device that liquid crystal molecules can be moved into different states when voltage is applied and the angle of visual field can be enlarged by forming a voltage controlling film having a region with different dielectric const. on a conductive film. CONSTITUTION:Displaying is performed by applying voltage between a conductive film 13 and another conductive film on the opposite side of a liquid crystal 17 to the conductive film 13 so as to move liquid crystal molecules of the liquid crystal 17. In this method, a region 14a, 14b having different dielectric const. is formed in an insulating film 14 so that even when voltage is applied, effective voltage applied on the liquid crystal molecules differs according to regions. Namely, since the dielectric const. in the region 14a, 14b, is higher than other region, relatively larger voltage is applied on the liquid crystal molecules in the region 14a, 14b compared with the rest of molecules. Therefore, compared with the tilt angle A of liquid crystal molecules in the region 14a, 14b, tilt angle B of liquid crystal molecules in other region is made smaller. Thus, the angle of visual field is enlarged in the liquid crystal display device.
