Title: Storage device
Inventor: SENGOKU SHINJI
IPC: G11B20/18
Filed: 1987-07-10
Abstract: PURPOSE:To prevent a dissipation accident of information of a recording medium, by detecting whether a reproducing error exists or not at the time when an ambient temperature of a head is different from a steady the temperature, and detecting a fact that a fluctuation range of a temperature in which the reproducing error is not detected has become narrower than a prescribed range. CONSTITUTION:The titled device is provided with a temperature control circuit 21 for controlling the ambient temperature of a head, and a temperature fluctuation margin detecting circuit 22 for detecting whether a reproducing error exists or not at the time when the ambient temperature of the head is different from a steady temperature, detecting a fact that a fluctuation range of a temperature in which the reproducing error is not detected has become narrower than a prescribed range, and outputting an abnormality detecting signal D. In such a way, since the increase of a frictional resistance between the head and a recording medium is detected by enlarging the fluctuation of a reproducing signal to a load fluctuation, the information of the recording medium can be stored in other storage device before the head falls to the recording medium, and the dissipation of the information can be prevented.

Title: Foreign matter inspecting device for liquid crystal substrate
Inventor: CHIKAMATSU SHUICHI
IPC: G02F1/1333
Filed: 1993-06-17
Abstract: PURPOSE:To detect a foreign matter with scattered light as for the liquid crystal substrate which has many rectangular patterns with large steps by separating and detecting the scattered light by sensors and deciding the foreign matter when respective detection levels are nearly equal. CONSTITUTION:The pattern of pixels is irradiated with the laser beam A from an irradiation system 2 with wavelength lambda1 and the laser beam 3 from an irradiation system 3 with wavelength lambda2 opposite at an angle of 45 deg. respectively. Consequently, scattered light A+B of the laser beams A and B is made incident on the objective 4a of an objective optical system 4 as for the foreign matter 10. The outputs of the sensors 4g and 4h, therefore, become almost equal, and their values when exceeding certain values larger than threshold values THa and THb are amplified by amplifiers 6a and 6b respectively and inputted to a dividing circuit 6c. At this time, the division result of the dividing circuit 6c between the input signals is almost '1'. Then a foreign matter deciding circuit 6d decides the foreign body when the output of the dividing circuit 6c is '1' nearly '1'.
