Title: Square type rotary shaft
Inventor: HISHIKAWA TAKAAKI
IPC: F16C3/02
Filed: 1985-07-01
Abstract: PURPOSE:To prevent ricketiness in advancing pair part by setting the arc of the corner part of an inner layer pipe larger than that of an outer layer pipe. CONSTITUTION:A square type outer layer pipe 2 is combined with an inner layer pipe 3 with makes contact with said pipe 2 so that corner parts of both pipes are united together. Further, the arc of the corner part of the inner layer pipe 3 is set larger than that of the corner part of the outer layer part. Since such a structure lessens the arc of the corner part, in case it is applied to the square-shaped rotary shaft, precision of fitting of said shaft to a feed shaft 10 on the like in advancing pair is improved and ricketiness does not occur.

Title: Key device for car
Inventor: SAKURAI TAKETOSHI
IPC: B60R25/04
Filed: 1994-06-28
Abstract: PURPOSE:To receive a code signal transmitted from the key side at a high S/N ratio. CONSTITUTION:A feeding coil 27 is mounted on the IG key cylinder side and the key side is supplied with electricity from an AC power 36 while a high-frequency signal from the key side is received under a resonating state by a resonance circuit 33, and inputted to a control circuit 44 through a detector 38. A receiving coil 30 is installed on the key side and a capacitor 48 is charged through a rectifier circuit 46, and a code-signal generating circuit 49 is supplied with electricity. The code-signal generating circuit 49 outputs a high-frequency signal modulated by a code signal to a transmission coil 31. The control circuit 44 receives the high-frequency signal from a key inserted into an IG key cylinder, compares the code signal and a stored natural code signal, and decides suitability. When both code signals do not coincide, the signal of an IG switch is made ineffective. Since the frequency of the high-frequency signal and the AC power largely differs, an S/N ratio is increased and feed and transmission are quickened and ensured even when feed and transmission are conducted simultaneously.

Title: Mask holder
Inventor: KARIYA TAKUO
IPC: G03F9/00
Filed: 1988-06-15
Abstract: PURPOSE:To prevent damages to masks due to the collision of a mask with a mask chuck by a method wherein a means for detecting the positions of a mask and a mask holder carried is provided, and an attraction force is exerted or not according to the result of the detection by the means and a carry means is controlled. CONSTITUTION:After a mask 8 is grasped by a hand 11 at a lower position, the motor 13 of an up-and-down movement apparatus 14 is driven and the mask 8 is moved toward the bottom surface of a mask chuck 9. At this juncture, a current for demagnetization flows through a coil 3 and the attraction force of a permanent is 0 or substantially negligible seemingly. While the mask 8 is rising, a light sensor detects the position of the mask. When the mask contacts the chuck, a circuit 19 generates a contact signal. The demagnetization current is cut out by this signal and a mask frame is attracted by the permanent magnet. The mask is held by the permanent magnet in this manner after the fact that the mask and the mask chuck are very close to each other or in contact with each other is confirmed. Therefore, strong impacts due to collision are not given to the mask at chucking.
