Patent JP-H0229945-A (JP)
Title: Light pickup
Inventor: EMOTO MASAMI
IPC: G11B11/105
Filed: 1988-07-27
Abstract: PURPOSE:To reduce output fluctuation due to return light on driving a semiconductor laser at a low output by arranging a 1/4 wavelength board in an optical path from a beam splitter to an objective lens in the recording/reproducing of a postscript type optical disk and making a optical axis direction different on recording and on reproducing. CONSTITUTION:On recording, a 1/4 wavelength board 14 arranged between a beam splitter 3 and an objective lens 5 is inclined for 45 degrees to the polarizing direction of incident irradiating light by a rotational device. Thus, S polarization from a laser diode (LD) 1 is reflected by the beam splitter 3, becomes circularly polarized light to transmit through the wavelength board 14 and records information. On reproducing, the wavelength board 14 is set parallel or vertically to a polarizing face, and the LD 1 is driven at a low output. Then, when reflected light from a disk 6 is transmitted through the wavelength 14, it is converted into P polarization, is transmitted through the beam splitter completely, and is incident on a light detecting system 20. Consequently, it is not incident on the LD 1 as a return light, and the output fluctuation is reduced.

Filed: 1983-10-06
Abstract: PURPOSE:To collect efficiently empty car data by counting a waiting time when a taxi is empty, setting each time slot based on the set mode for traffic jam and slack hour and transmitting it to a base station. CONSTITUTION:When a taxi 1 enters a district, receives a position signal from a sign post 3 and a taxi meter 12 indicates an empty car, a timer is operated via a timer reset circuit 9 to count the waiting time. When a polling signal from the base station 2 is received (20), the signal is fed to a dynamic data generating circuit 11 and a collating circuit 28. The circuit 28 changes over a selector switch 29 to any of the traffic jam mode 14a and the slack hour mode 14b when the district designation by polling and the position signal from the sign post 3 are coincident, a prescribed time slot set by each mode is fed to the circuit 11 via a gate 10 in response to the waiting time of a timer 13 and car number data from a car number setting circuit 15 is fed to the base station 2 via a transmitter 18. The base station 2 displays the dynamic data of the taxi on a display device 25.

Title: Fishing float
Inventor: SAKO ATSUSHI
IPC: A01K93/02
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a fishing float enabling the slow and stable sedimentation of a fishing bait and capable of obtaining strike (baiting off, baiting up or drawing during the course of sedimentation, drawing during presence at the bottom, and drawing during floating) in the all courses (the course of sedimentation, lying at the sea bottom and floating at a specific water depth). SOLUTION: This float has a waterwheel engaged in a float and rotating due to the shift of a fishing line, and this enables the slow and stable sedimentation of the fishing line. The waterwheel has a physical property that the flow resistance increases with the increase in the number of rotation. Thereby, the fishing line having a weight settles in a slow and stable manner. Fish's actions on the bait attached on the line change the force applied on the fishing line, and changes the number of rotation of the waterwheel and causes the change of water depth of the float, and thereby, the strike can be detected.
