Title: Optical fiber rotational angular velocity sensor
Inventor: KAJIOKA HIROSHI
IPC: G01C19/72
Filed: 1988-12-27
Abstract: PURPOSE:To make a sensor small in size and light in weight and to mount a rotor by connecting an optical system on a fixed side and an optical system on a movable side through an optical rotary joint. CONSTITUTION:In a sensor, the optical system on the fixed side in which a light source 1 and light receiving part are connected to the incident ends of a 2X2 optical directional coupler 2a and a polarizer 5 is connected to one of the exiting ends and the optical system on the movable side in which a 2X2 optical directional coupler 2b having a polarization separating function is connected to the end sides of an optical fiber loop 3 are connected through the polarized plane maintaining type optical rotary joint 4. Since the joint 4 is in the polarized plane maintaining type, polarized wave in a slow axis mode fetched from the polarizer 5 is conducted to the optical system on the movable side as it is. Owing to the polarization separating function of the optical directional coupler 2b of the optical system on the movable side, the light is separated to clockwise and counterclockwise light propagated in the optical fiber loop 3 and combined again as the orthogonaly polarized wave to be made incident on an optical reception part. Then, a phase difference between the clockwise and counterclockwise light propagated in the optical fiber loop 3 is detected by a measuring system.

Title: Can lid
Inventor: ISHIZAKI HIROSHI
IPC: B65D17/32
Filed: 1992-12-08
Abstract: PURPOSE:To provide a can lid which can prevent the content from guishin out much even when the inner pressure in the can rises up abnormally. CONSTITUTION:When the inner pressure of a can rises up abnormally, at first, a breakage is brought about at the thin part 61a in main scored. lines 61 and the gas and the liquid of the inside are leaked out from the breakage. Since this part 61a is covered with a tab 10, the leaked gas and liquid is prevented from guishing outward. When a breakage occurs and the contents leak out once, the inner pressure decreases as much as the quantity. Accordingly, other parts except the main scored lines 61 can be prevented from breaking. In this way, the content can be prevented from leaking much.

Filed: 1989-12-20
Abstract: PURPOSE:To give the stable spot of a diffraction limit to temperature variation and mechanical fluctuation by constituting a conical type prism for condensing second harmonic wave by sticking materials having different refractive indexes to each other and correcting chromatic aberration. CONSTITUTION:A light beam having a specified wavelength from a semiconductor laser 1 is condensed by a lens 2, guided to a fiber-like nonlinear material 3 and the second harmonic wave is generated at a radiation angle alpha.
