Abstract: PURPOSE:To surely shield, from a lens, illuminance light given to parts other than the surface of an original and to miniaturize the title device by disposing a reflecting member in such a position as to shield said illuminance light from an illuminating light source. CONSTITUTION:An original 1 on an original platen panel 4d is irradiated by a lamp tube 4c, and the illuminance light is emitted radially in all spherical angles from the tube 4e which is the center. Among illuminance light rays not furnished directly on the original 1, those from the rear side of the lamp tube 4e are shielded by a rear reflecting plate 4g, and these reflected rays of light indirectly irradiate the surface of the original. Also, rays of light from the front side of the tube 4e are shielded by the sub-reflecting plate 4i, and reflected by its reflecting surface 4r onto the surface of the original. In the meantime, rays from the lower side of the tube 4e are reflected by a mirror 5c out from an image beam optical path L, pass through a lens 5d and shielded not to be made incident on a photodetective element 5e. Such light beams as incident on mirrors 5a, 5b, 5b' are also reflected out from the optical path L not to be made incident on the lens 5d. As a result, not so large a shielding plate is necessary hence the title device can be miniaturized.

Abstract: PURPOSE:To improve manufacturing yield rate and to decrease costs, in manufacturing a CMOS type IC having an LDD structure using a self-alignment processes, by forming low-impurity-concentration source and drain regions without using masks such as photoresist with respect to two complementary MOS type transistors. CONSTITUTION:On gate insulating films 16A and 16B, which are arranged on the surface of a semiconductor substrate 10, gate electrode layers 18A and 18B comprising polysilicon are formed. Then a photoresist layer 20 as an impurity mask is formed so as to cover an opening part 14A and to expose an opening part 14B. Thereafter, a P<+> type source region 22 and a P<+> type drain region 24 are formed. Under the state where the opening parts 14A and 14B are not masked, e.g. phosphorus ions are selectively implanted in the surface of the substrate with the laminated parts of the gate insulating films 16A and 16B and the gate electrode parts 18A and 18B and the field insulating film 14 as masks. Thus, an N-type source region 26 and an N-type drain region 28 are formed on one side and the other side of the gate electrode layer 18. In the P-channel MOS type transistor, P<+> type source and drain regions are formed so as to erase the N-type source and drain regions. Thus the processes are simplified.

Title: Controlling method of bolt axial force
Inventor: TAKEDA SAKAE
IPC: G01L5/24
Filed: 1982-01-14
Abstract: PURPOSE:To control the axial force of a bolt for clamping plural bodies in one body by equipping the bolt with a detector for acoustic emission, and detecting strain energy generated in the bolt through the detector. CONSTITUTION:At the head of the bolt 1, the detector 11 for acoustic emission (AE) is equipped to detect an elastic wave 12 of strain energy emitted during clamping. This elastic wave 12 is led out in the form of a signal waveform. The relation between individual AE and the strain epsilon of the bolt 1 in clamping is found as a characteristic line 13. Further, a characteristic line 15 shows the relation between stress sigma and strain epsilon. When the engagement part between the bolt 1 and a nut 2 becomes a plastic area, the signal waveform of AE has maximum amplitude 14. For this purpose, the clamping of the bolt 1 is stopped when the maximum amplitude 14 is obtained in clamping, thus performing accurate axial force control.
