Title: Optical fiber polarizer
Inventor: MASUDA SHIGEFUMI
IPC: G02B5/30
Filed: 1983-06-21
Abstract: PURPOSE:To obtain a polarizer equivalent to a lambda/4 and a lambda/2 plate which eliminates the need for a rotator, polarizer, and lens, by using an optical fiber. CONSTITUTION:For example, DELTAbeta=(2pia.r<2>)/lambdaR<2> (a: coefficient of coupling), where Z and (r) are the winding direction and radius of the optical fiber and R and DELTAbetarad/m are the radius of curvature and refractive index. In this case, the value DELTAbeta varies with R and (r), and values of plural matrixes of light vary to shift the direction of polarization. Thus, when the coherent light having polarizing characteristics is incident to one terminal, the polarizer which changes the direction of polarization at the other terminal is obtained. In this case, the optical fiber can not be wound only by itself, so the optical fiber 11 is put in the copper- made tube 12 from its cut 12a. Then, the tube is wound to secure the wound state of theoptical fiber 11.

Title: Direct injection type diesel-engine
Inventor: KAWASHIMA JUNICHI
IPC: F02B23/06
Filed: 1990-04-26
Abstract: PURPOSE:To promote the recombustion of unburnt HC or the like by forming and opening a secondary air introduction hole communicated to a clearance part at the upper end of a cylinder, in the side surface of a communication passage opened to a disturbing combustion chamber and a main combustion chamber, so as to introduce air as secondary air from the clearance part into a gas jet stream fed from the disturbing combustion chamber. CONSTITUTION:When a piston comes up to a position in the vicinity of its top dead center during compression, main fuel is injected and fed into a main combustion chamber 5 from a main fuel injection valve 7. Meanwhile, air in a cylinder 2 is compressed within the combustion chamber 5 while being swirled so that vivid combustion is carried out at the initial stage of combustion. Then, a small volume of fuel is injected into a disturbing combustion chamber 9 from a counter fuel injection valve 11, and this fuel gas is jetted in the form of a gas jet stream which is led into the main combustion chamber 5 through a gas jet hole 15 at the front end of a communication passage 14. In this arrangement, in the communication passage 14 through which gas produced in the disturbing combustion chamber 9 flows, the jetted gas passes at a high speed so as to cross the inner peripheral side opening of a secondary air introduction hole 16. Thus, air in a clearance part 17 is sucked into the communication passage, and accordingly, it is possible to use this air as a secondary air for the jetted gas.

Title: Toner concentration detecting device
Inventor: EBI YUTAKA
IPC: G03G15/10
Filed: 1978-09-08
Abstract: PURPOSE:To keep the picture quality at high quality through detection of the drop of concentration of only the toner contributing to the development and simultaneous detection of the degree of deterioration of the developer, by detecting the concentration of the developer in a wet type electrophotographic device between the electrodes for electrophoresis. CONSTITUTION:Electrodes 4a, 4b are opposedly provided across the flow of the developer. When an electric field is applied to the flow by means of these electrodes, the toner charged negatively is attracted by the positive electrode 4b to migrate. As a result, a difference is caused between the concentration detected by an upstream side detector 4c and that detected by a downstream side detector 4d. This concentration difference represents the degree of deterioration of the developer. By feeding the concentration difference found by the detector 4 into a comparator circuit 7 and operating a toner supply solenoid 6 depending on the output from the circuit 7, a constant picture image concentration may be always obtained. Since the rate of the toner not charged, i.e., the deterioration of the developer, is also detected at the same time, unevenness of picture image may be prevented, so that the picture quality may be maintained favorably.
