Title: Formation of panel
Inventor: YAMAGUCHI NOBUYUKI
IPC: B23K26/352
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent the cracking at the time of forming a blank material by executing a laser beam joining to steel plates having different plate thicknesses by linearly hardening the steel plates crossing over a laser beam welded line before executing drawing formation. SOLUTION: The laser beam blank material 1 has the linear hardening part 14 crossing over the laser beam welded line 13 between the thick plate 11 and the thin plate 12. The part 14 is hardened almost vertically to the laser beam welded line 13 and the hardening pitch may be 17-40 mm. At the time of executing the formation to the laser beam blank material 1 applied with the hardening, since the tension strength of the thick plate 11 is larger than that of the thin plate 12, the mutual stretching is developed in the laser beam welded line 13 as the boundary between the thick plate 11 and the thin plate 12. In this result, the thin plate 12 tends to be stretched to the thick plate 11 side, but since the strength in the stretching direction becomes high by applying the hardening part 14, the thin plate 12 can be resisted to the stretching and the development of the cracking is prevented.

From the relation between its output (a) and a beam position, primary moment is found through cumulative adders 10 and 12, a multiplier 11, and a divider 13. This primary moment leads the center position of the mark 1 by a half as far as beam movement distance l corresponding to delay time. Therefore, the output of a subtracter 14 is as shown in figure and the center position of the mark 1 is thus found.

Title: Data interface circuit
Inventor: SERIKAWA ATSUO
IPC: H04L25/02
Filed: 1985-09-09
Abstract: PURPOSE:To reduce power consumption by making larger the output impedance of a driver in an idle time. CONSTITUTION:Since, in a data transmission time, a control signal representing that a data is in transmission is added on a control circuit 13 from a data transmission control circuit 17, the control circuit 13 controls a switch circuit 12 so as to be made on. Thereby, a resistor R3 is short-circuited and an impedance becomes a prescribed one by a resistor R0. Also, in the idle time, the control circuit 13 controls the switch circuit 12 so as to be made OFF. Thereby, the resistor R3 is connected to the resistor R0 in series, making larger the output impedance. Therefore, so that the output impedance becomes large even when the output voltage of a driver 11 is between +5V-+15V of high level or between -5V--15V of low level, an output current is reduced.

Title: Multiple-wave type interferometer
Inventor: OKURA TAKAHIRO
IPC: G01B11/30
Filed: 1990-07-27
Abstract: PURPOSE:To make it possible to measure irregular shapes in a specified wavelength region by scanning the Moire fringe of the obscure sum which is generated by the overlapping of interference fringes, making the Moire fringe clear, and obtaining the intensity distribution of the interference fringes based on the equivalent wavelength. CONSTITUTION:Under the state wherein the luminous fluxes from two light sources 1 and 2 are mixed, the luminous fluxes are rediated on a measuring surface 10. Then, the observed interference fringe is the Moire fringe of the sum. The interval between the Moire fringes agree with the interference fringes having the equivalent wavelength lambdae based on lambda1 and lambda2. The Moire fringe of the sum has the intensity distribution such as a beat signal wherein the fine intensity distribuion is present in a large waviness. When a reference plane 11 is moved along the optical axis. the intensity distribution of the interference fringe is changed in response to the moving amount of the reference plane 11. Under the state wherein two interference fringes are overlapped, the fringe scanning for one period is performed for wavelength lambda1 and lambda2. Thus, the clear equivalent interference fringe is obtained. Then, the equivalent wavelength for one period is divided into several parts, and the fringe scanning is performed. Thus, the phase distribution at the equivalent wavelength is obtained. In this way, the irregular shape in the region from several tens of mum to several hundreds of mum can be measured.
