Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber transmission path constituted to nearly completely offset the waveform distortion caused by the wavelength dispersion and Kerr effect of the transmission path by considering the change in the light intensity in the transmission path in the optical fiber transmission path formed by arranging a phase conjugation converter in mid-way of the optical fiber transmission path to offset the waveform distortion caused by the wavelength dispersion and Kerr effect of the transmission path. SOLUTION: The code diameters of the first and second optical fibers in respective microsections are set in such a manner that the ratios of the wavelength dispersion values in the microsections for the products of the light intensity and the constant of the Kerr effect in the first to n-th microsections of the first optical fiber 2 is equaled to the ratios of the wavelength dispersion values of the microsections to the product of the light intensity and the constant of the Kerr effect in the first to n-th microsections of the second optical fiber 4. The lengths in the respective microsections are so adjusted as to be proportional to the inverse number of the product of the light intensity and the constant of the Kerr effect of the microsections or the inverse number of the wavelength dispersion values.

Title: Method and device for getter flash of cathode-ray tube
Inventor: HIRASAWA SHIGEMI
IPC: H01J9/39
Filed: 1992-09-01
Abstract: PURPOSE:To efficiently perform sufficient getter flash by starting heating of a getter, and stopping this heating after a predetermined time, and then reheating the getter. CONSTITUTION:Heating of a getter is started at a high frequency output RF1. The getter is heated from a fixed temperature and at around 800 deg.C Ni and Al contained in a getter agent undergo a heating reaction and splashing of the getter starts as the temperature quickly rises. A second stopping time (t2) is provided, and when gas remaining in a tube because of the heating power RF1 of the getter agent causes a plasma discharge, the gas remaining in the tube is adsorbed by the evaporated getter within a time (t1). Next, heating for a third time is carried out again using high-frequency output power RF3 so that a required amount of getter is splashed within the cathode-ray tube and vapor-deposited. The required amount of getter can stably be vapor- deposited and the characteristic enhancement and life prolongment of the cathode-ray tube can be achieved.

Title: Infinitesimal position measuring device
Inventor: KOISHI YU
IPC: G01B9/04
Filed: 1994-09-02
Abstract: PURPOSE: To provide an infinitesimal position measuring device capable of relatively simply measuring the thickness of the layer of a layered sample from sub-micron to several mm. CONSTITUTION: A laser diode 12 applied with a constant forward current by a laser diode driving power source 16 emits a fixed quantity of light. The light forms a light spot in a sample S via a confocal optical system 20. The reflected light from the sample S is again returned to the light source 12 via the confocal optical system 20. A piezo-stage 26 scans the position of the confocal optical system 20 in the optical axis Z-direction, and the light quantity fed back to the light source 12 is increased when the light spot hits the boundary surface in the sample S. The increase of the light output is detected by a photo-diode 14.  An arithmetic control device 30 calculates the positions of boundary surfaces in the optical axis Z-direction of the sample S from the position of the confocal optical system 20 by the scanning means 26 when the light output is doubled and calculates the distance between the boundary surfaces from the positions of the boundary surfaces.

Title: Recording or reproducing device
Inventor: TAKANO MASAMICHI
IPC: G11B19/16
Filed: 1988-09-19
Abstract: PURPOSE:To smoothly perform an action with a set mode by providing a setting means to set the switching of a recording mode and a reproducing mode and a control means to make ineffective the setting of a setting means when the switching setting of the setting means is a prescribed time or below. CONSTITUTION:A setting means sets the switching of a recording mode and a reproducing mode and a control means makes ineffective the setting of the setting means when the switching and setting of the setting means is a prescribed time or below. Namely, a mode setting switch 105 provided on a camera main body can be switched to respective modes by operation. A system controller 91 stores a previous operating mode excluding a log mode selected by the mode setting switch 105, and when the operator of the mode setting switch 105 is positioned at respective operation mode positions for a prescribed time, the controller executes the control action as the fact that the operating mode is selected and set. Thus, the smooth action at the set mode can be executed.
