Title: Screening device for optical fiber
Inventor: ITO TERUAKI
IPC: G01N3/00
Filed: 1994-09-30
Abstract: PURPOSE: To provide an optical fiber screening device which precludes such inconvenience in case where the terminating processing is made by hand operation, that the optical fiber is damaged by application of any excessive force or that a low strength fiber of poor workmanship is overlooked. CONSTITUTION: The end of an optical fiber covering 420 is pressed from above and below with a clamping means 22, and the tests are conducted while a lifting/lowering means 32 is operated in a position a certain distance apart therefrom. As the cutting length of an optical fiber 422 is constant, its free end is lifted or lowered a certain distance, set off from the means 32 when it is bent, and returned to the horizontal attitude. Accordingly, a constant flexural stress is applied at all times, and the tests are conducted under constant conditions.

Title: Optical switch
Inventor: KODA SHIGETO
IPC: G02F1/137
Filed: 1989-10-06
Abstract: PURPOSE:To realize the optical switch which can obtain a large deflection point, and also, can set arbitrarily a deflection angle by allowing a polarized light having the vibration surface being parallel to an optical axis of a liquid crystal to be made incident on the liquid crystal from the normal direction of one substrate, and varying a voltage impressed on the liquid crystal. CONSTITUTION:With respect to a liquid crystal 14 brought to uniaxial orientation, inserted and held between a pair of transparent substrates 11a, 11b, a polarized light IPL having the vibration surface being parallel to an optical axis of the liquid crystal 14 is made incident from the normal direction of the substrate 11a. In this state, when '0'V or a sufficiently low voltage Va is impressed between transparent electrodes 12a, 12b, molecules of the liquid crystal 14 are scarcely varied from an initial state, and an incident polarized light travels straight roughly. On the other hand, when a voltage Vc higher than a threshold voltage of the liquid crystal 14 is impressed, molecular axes of the liquid crystal 14 become roughly parallel to the direction in which an electric field is impressed, and the polarized light IPL is outputted as a transmission polarized light TPL. When the impressed voltage is an intermediate value, the molecular axes of the liquid crystal become a state oriented at an angle phi, and the incident light beam IPL becomes an abnormal light beam, and shifted by a distance X.

Title: Recording head with erasing function having extended width
Inventor: JIYOOJI AARU BARIAN
IPC: G11B5/024
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To perform not only a recording function but also an erasing function without using an erase head by using a record head when an azimuth recording format is used. SOLUTION: At the time of performing a recording on a first track with a selected azimuth, a wide recording head having a width almost twice as wide as a recorded track pitch performs a recording on the track by the rear half of the head and performs an overwriting on an adjacent track by the front half of the head. A recording processing erases an arbitrary old recording in the adjacent track substantially without necessitating a preceeding erase head. On the adjacent track, the head performs an overwriting later by the rear half of the head with azimuth and the head performs an erasing on a next track by the front half of the head. In the recording technology of the double width, the azimuth recording format is used.
