Title: Alignment mark
Inventor: RAFUAERU ERU REBUIIN
IPC: H01L21/30
Filed: 1992-09-24
Abstract: PURPOSE: To provide a matching mark which is used for controlling the relative positions of more than two objects and for arranging the objects. CONSTITUTION: A matching mark 10 consists of dots, and the dots of a horizontal line contain dots 14, 16 and 18. A frequency in the center of the horizontal line is maximum at the dot 16 near the center of the horizontal line. The frequencies of the dots 14 and 18 reduce in proportion to a distance of detachment from the center. The matching mark 10 contains the dots of at least one vertical line, dots 20, 22 and 24, for example. The frequency at the center of the vertical line is maximum at the dot 22 near the center of the horizontal line.

Title: Overlay inspection method of semiconductor element
Inventor: HAI SOUMAN
IPC: H01L23/544
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To obtain an accurate overlay correction value by a single measurement by comparing mean value of measurement of the islands of inner marks, islands and lands formed on lands isolated from them but covering the entire surface with outer marks measured values to obtain an overlay compensating value. SOLUTION: Inner marks 43 and 44 are composed of islands 43 formed inside an outer mark 42 and lands 44 which are isolated therefrom with fixed width and coated on the entire surface. The overlay of a semiconductor wafer 41 of this structure is measured such that side edges 42a and 42b of the outer mark 42 are accurately measured, and the coordinates of above-seen both side edges 43a and 43b of lands 43 of the inner marks are detected to detect lands 44b and 44c. The mean values of the detected parts 44b and 43a and mean values of those 44c and 43d are recognized as position coordinates of new inner marks. Then, referring to these values, the distance from the outer mark 42 is inspected to compensate the overlay.

Title: Back-tensioning device for rolled form sheet
Inventor: SAKAGAMI KENJI
IPC: B41J15/16
Filed: 1984-11-30
Abstract: PURPOSE:To prevent an ink sheet from sagging, by providing a roller pressed against an outer peripheral surface of a holder through a shaft body and a means for restricting rotation of the roller when a torsion spring is twisted to a predetermined extent. CONSTITUTION:When a transferring action is performed after an upper frame 1 is closed, the shaft body 17 comes into contact with a stopper 22 on being oscillated by a predetermined amount, and is prevented from coming closer to the protective plate 14, whereby the pressing force of the roller 16 against the outer peripheral surface of the protective plate 14 is weakened, and a restoring force of the torsion spring 21 exerted on the holder 6 is restricted. Thus, during the transferring action, the resisting force exerted on the holder 6 is adjusted, and the sheet 4 is back-tensioned to such an extent as not to obstruct a paying-out operation. Even after the transferring action is finished and payout of the sheet 4 is topped, the spring 21 remains twisted to a certain extent, and the roller 16 remains pressed against the outer peripheral surface of the protective plate 14, so that the sheet 4 is maintained in the state of being back- tensioned. Accordingly, the sheet 4 is securely prevented from sagging, even in a stand-by state.

Title: Information recording and reproducing device
Inventor: TSUBOI NOBUYOSHI
IPC: G11B7/0045
Filed: 1984-12-03
Abstract: PURPOSE:To erase stably recorded information by providing a means for detecting the recorded state of a recording medium and controlling optimizedly thermal energy supplied at recording and erasing. CONSTITUTION:A reflected light beam 204 from the recording medium 1 is detected by the photodetector 7 of an optical system 200 to attain a reflection intensity 206, and a reflected light intensity correcting circuit 120 corrects a variety of intensity in writing, erasure and reproduction modes and outputs a corrected and reflected light intensity 122. It is inputted to a laser output correcting circuit 150 which outputs a corrected value 152 corresponding to the corrected and reflected light intensity 122. An instruction value 94 takes a positive value, and increases a laser drive signal 102. When a corrected value 152 is larger than a reference value 92, namely, reverse to said case, the instructed value takes a positive value and reduces the laser drive signal 102. Thus the intensity of a laser beam 111 is controlled so that the reference value 92 can be equal to the corrected value 152, whereby the stable recording, reproduction and erasure can be executed.

Abstract: PURPOSE:To improve the accuracy when the position start end detection in the track direction is retrieved at a high speed by forming on a specific recording medium a rotation start end detection mark for detecting rotation of an optical disk and an address start end detection mark for detecting the position of the address area on each track. CONSTITUTION:The recording medium is formed with metal or alloy for forming the crystal structure different from an equilibrium phase at a room temperature by quenching it in the solid state at a high temperature. On the optical disk 2 the address start end detection mark 3 for detecting the position in the address area on each track is formed in the circular arc of the same angle as that in the address area 1 of an index area 7. In the area 7 the rotation start end detection mark 5 for controlling the rotary phase of a disk motor for rotating the optical disk is formed in the track direction with an uneven phase structure. Thus the rotation start end position, address start end position and sector start end position can be stably detected at high speed retrieval.

Abstract: PURPOSE:To perform stable illumination even when light quantity of a light sensor is suddenly changed by providing a hysteresis circuit and a delay circuit. CONSTITUTION:Circuit power is supplied from a battery 1, and circuit protection and action stabilization are performed by a power supply circuit 3. a current at an optical sensor 2 is converted into a voltage to be inputted to a lighting/ lighting off determination circuit 4 provided with hysteresis, and when the voltage signal is less than a specified voltage, a voltage of 0V is outputted to a delay circuit 5 to put a relay 6 on immediately for lighting an illuminating lamp 17. When the inputted voltage signal into the circuit is the specified voltage or more, a voltage of 5V is outputted to the circuit 5, and only in the case where this output continues for a specified delay time or more, the relay 6 gets off to light off the illuminating lamp 7. In the meanwhile, the set specified delay time is changed as a capacitor capacity inside the circuit 5 changes. Stable illumination is thus provided even when light quantity of a light sensor is suddenly changed.

Title: Resonance type knock sensor
Inventor: INUZUKA AKIHITO
IPC: G01H11/08
Filed: 1984-12-05
Abstract: PURPOSE:To make the rise and the fall of an output signal sharp by connecting a control material to an oscillation sensing member where a piezoelectric element is stuck to one face of a metallic thin plate. CONSTITUTION:A ring-shaped piezoelectric element 12 is stuck to the upper face of a ring-shaped metallic thin plate 11 to constitute the oscillation sensing member. An Si rubber 20a is stuck as a damping plate to the lower face of this thin plate 11. Since the rise and the fall of the output signal are made sharp, the output signal having a knock waveform whose number of tops is small reaches a threshold value more early by the quick rise, and the knocking oscillation can be detected. Even if knocking intervals are short, superposition of rise and fall outputs is suppressed to make the bottom sharp. Thus, the rise of the threshold value is suppressed to improve the S/N.
