Title: Optical sensor
Inventor: MASUDA TAKESHI
IPC: G01C1/00
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To detect the emitting direction of light at a high detecting speed with little error without performing a light emitting directional angle calculation such as tangent calculation considering the position of a light receiving element which received the light and the position of an opening by arranging the light receiving element of an optical sensor for detecting the emitting direction of light on a spherical surface around the opening part. SOLUTION: This optical sensor 1 is formed of a casing 2, a slit 3 formed on a solar light receiving surface 2a, a one-dimensional CCD 4 as a light receiving element arranged in one direction within the casing, and a DDC signal processing means 6. The one-dimensional CCD 4 is arranged on the circumference around the slit 3, and when a solar light 5 is incident on the one- dimensional CCD 4 through the slit 3, the detection signal from the one- dimensional CCD 4 generated by being irradiated with the solar light 5 is guided to the CCD processing means 6. Since the one-dimensional CCD 4 is arranged on the circumference around the slit 3, the CCD element which received the solar light 5 shows the angle of the solar direction as it is.

Title: Treatment/disposal of refuse or waste oil
Inventor: KADOTA KATSUMI
IPC: B65F1/00
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To store the refuse in a storing vessel properly and with high operability and to dispose the refuse without staining one's hands or fingers by putting the refuse into the storing vessel via a funnel and by pushing the refuse, which is sticking to the funnel, into the vessel by means of a push-in means. SOLUTION: In treating/disposing the refuse or waste oil, the refuse or waste oil is put into a storing vessel 1 via an opening means 2, which enlarges the sectional area of an opening of the waterproof storing vessel 1 for disposal. In this case, if there is the refuse sticking to the surface of the opening means 2 or to the upper side of the storing vessel 1, the refuse is pushed into the storing vessel 1 by using a push-in means 3, and then the opening means 2 is removed from the storing vessel 1. When there remains a storing space within the storing vessel 1, the opening part is fixed by a fixing means 4. When the refuse or waste oil is brought again, the fixing means 4 is disengaged. This process is repeated until the storing capacity of the storing vessel 1 is reached.  Then, the opening part of the storing vessel 1 is sealed by using a sealing means 5 so as to dispose the refuse or waste oil.

Filed: 1990-11-02
Abstract: PURPOSE:To obtain a second higher harmonic with high conversion efficiency by coinciding the propagation constant of a fundamental wave with that of the second higher harmonic in such a state that wave-guided light is closed in a light waveguide. CONSTITUTION:After the end faces 1a, 1b of a substrate 1 are polished, laser light X from a semiconductor laser element 5 is entered from one end face 1a of a light waveguide 2 with lenses 4a, 4b to obtain a second blue-colored higher harmonic A from the end face 1b at the light waveguide 2.

Title: Orthogonally polarized wave output device
Inventor: ITO TOSHIO
IPC: H04B10/588
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To provide an orthogonally polarized wave output device which is resistant to waveform distortion and which improves a digital error rate. SOLUTION: An RZ-signal pulse string having a frequency α [Hz] is applied to a PLC waveguide 102 preserving the polarized plane of a signal light. In an optical branching circuit 103, the pulse string is branched into two optical paths 102a, 102b while maintaining the polarized plane of the PLC waveguide 102 and the optical paths 102a, 102b are multiplexed to an optical path 102c in an optical multiplexing circuit 108 while maintaining polarized planes. The two optical paths 102a, 102b are set so that difference between propagation times of the pulse string due to the difference between optical path lengths becomes to be 1/(2α) [s].  The side of the optical paths 102a, 102b, for example, the path 102a preserves the polarized plane of a mode-locked laser 101 and the path 102b of the other side has an element 104 for the 90-degree rotation of polarized plane in order to rotate the polarized plane of the laser 101 vertically. Consequently, in a pulse string to be transmitted, polarized planes cross at right angles every one bit. As a result, intercode interference among adjacent pulses become weak and there is an effect that this device becomes to be resistant to waveform distortion. Moreover, since a light power is dispersed between respective polarized planes, the device becomes to hardly receive the nonlinear effect of an inductive Brillouin scattering or the like. Thus, there is an effect that the device improves a digital error rate.
