Title: Optical deflecting element
Inventor: MIYAZAKI HIROYUKI
IPC: G02B5/04
Filed: 1987-04-15
Abstract: PURPOSE:To obtain an optical deflection by a repeated frequency of a high speed, by using a deflecting element which is a cylindrical rotor, and has a structure by which thickness in the axial direction of the rotor and a gradient in the tangential direction are changed continuously. CONSTITUTION:An optical deflecting element 1 is a cylindrical rotor whose center axis 3 rotates, and a light beam is made incident vertically onto the paper surface at an incident point 2. The incident side end face is partitioned, for instance, into four blocks in the peripheral direction, and in each block, thickness dk in the axial direction at the incident point becomes minimum d0 in the center and maximum d1 in both ends, and changes continuously. Accordingly, as the optical deflecting element 1 rotates, the light beam is deflected. This element is a light transmissive type, and placed coaxially with a light source and a motor. It is obtained at a low cost by using plastic, etc.

Title: Noise control system
Inventor: FUKUMIZU KENJI
IPC: G10K11/16
Filed: 1991-03-29
Abstract: PURPOSE:To shorten a time required until a muffling effect can be obtained after a system operation is started. CONSTITUTION:A residual noise observation part 4 is arranged at a point from where a noise is desired to eliminate, and a residual noise in which the noise propagated from a noise generation source 50 is added on a secondary sound propagated from a secondary sound source part 3 is inputted to the part 4. An adaptation part 5 adapts the processing of a signal processing part 2 so as to reduce an output signal based on the residual noise observed at the residual noise observation part 4. Meanwhile, a processing content when a system is operated in the past is stored in a processing storage part 6, and when the system is operated again, noise control processing is started by initializing the processing content in the past stored in the processing storage part 6. Thereby, it is possible to shorten a time until the muffling effect can be obtained after the system operation is started.

Abstract: PURPOSE:To prevent accidents such as overflow and low water level by receiving a signal from a level-measuring equipment on a fluid liquid surface which is installed in one bath of a two-bath tank and then installing an automatic value for controlling a level which determines a valve opening within a return pipe. CONSTITUTION:A level-measuring equipment 17 for measuring a liquid surface level of a liquid B is provided at one tank 1B and a signal from the measuring equipment 17 is sent to a level controller 18.

Title: Current mirror circuit
Inventor: SHINOMIYA KOUJI
IPC: H03F3/34
Filed: 1984-05-09
Abstract: PURPOSE:To obtain a current mirror circuit which can work the power supply voltage of a low level by using a negative feedback loop formed by the inverted Darlington connection. CONSTITUTION:The inverted Darlington connection is secured between transistors (TR) Q2 and Q3. When a TRQ1 is actuated, a current flows to the collector of the TRQ1 from the base of the TRQ2. Then an amplified current flows to the base and the collector of the TRQ3. Thus the negative feedback is applied. A steady state is secured when the reference level of a constant current source I0 is equal to the level of the collector current of the TRQ1. Therefore the base- emitter voltage of the TRQ1 is kept constant and supplied to each base and emitter of output TRs QL1-QLn. Thus the fixed reference voltage I0 is supplied to loads RL1-RLn respectively. Thus it is possible to obtain a current mirror circuit which can work with the power supply voltage of a low level.
