Abstract: PURPOSE:To light an arcuate surface to be irradiated uniformly, to obtain the same effective light-source image on the whole surface in an irradiation region and to attain high illumination efficiency by particularly arranging first and second optical means having a predetermined shape to one part of a lighting optical system. CONSTITUTION:Luminous flux from a light source 15 is condensed to the plane of incidence of a first optical means 17 by a converging optical system 16. A second optical means 18 is constituted of optical fibers, and the plane of incidence thereof is faced oppositely to the plane of the first optical means 17 and has approximately the same shape as the plane of projection of the first optical means 17. The plane P1 of projection of the second optical means is formed to an arcuate shape. A third optical means 100 has two optical systems of an optical system 19 and an optical system 20 and a stop 21 disposed near a pupil surface. Luminous flux from the plane PI of projection of the second optical means 18 is condensed onto a first irradiating surface M1 by the third optical means 100. Accordingly, an arcuate irradiation region is formed onto the first irradiating surface M1, and an effective light-source shape is equalized extending over the whole surface of a mask arranged onto the surface M1, and the mask is irradiated uniformly.

Filed: 1989-09-29
Abstract: PURPOSE:To prevent noise obstruction by disposing choke coils having each prescribed composition between each core wire of an electric cable connecting an electric circuit to a power source and the power source, and between the outer shield layer and a ground terminal. CONSTITUTION:An electric circuit 1 of a computer, for example, is connected to a power source 8 through an electric cable 3 having the outer shield layer 5. A choke 7a is interposed in each core wire of phases R. S. T. of the electric cable 3.

IPC: G11B7/005
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To extract accurate land pre-pit by obtaining a couple of read signals which are optically split in the parallel portions for the tangent direction of the track and extracting a difference of the compensated read signal which is matched in the potential of the unrecorded portion with the recorded portion. SOLUTION: A predetermined mark AGC sample pulse and space section clamp pulse are generated and these pulses are applied to the sample hold circuits 23, 26 or 33, 36 of the potential compensation circuit. Thereby, the voltage V1 of the space section is fixed to 0 V and the voltage V2 of the mark section to the predetermined potential respectively. Thereby, amplitude difference between the mark and space of a couple of split RF signals SDRF1, SDRF2 can be balanced. Only the RF signal element is canceled by inputting a couple of RF signal outputs output via each potential compensation circuit to a radial push-pull circuit 4 and thereby stable LPP can be extracted.

Title: Magnetic recording and reproducing device
Inventor: OBATA SHIGEO
IPC: G11B15/44
Filed: 1986-10-29
Abstract: PURPOSE:To make a brake member and a plunger, etc. unnecessary and to remarkably make an apparatus small in size and light in weight, by stopping the feeding-out of a tape by rotating a motor in reverse, at the time of shifting to a stopping state. CONSTITUTION:A rotational force of a motor 1 is transferred to a gear 8 through pulleys 5, 7 and a belt 6, and transferred to a roll-contact gear 10 of a turning arm 9 on the same axis. This turning arm 9 turns in the same direction as a driving gear, and drives a winding reel base 4a or a supply reel base 42. For instance, at the time of shifting from fast forwarding to a stopping state, when the motor 1 is rotated in reverse, the rotational force is transferred to the reel base opposite to the reel base to which said force is transferred until that time, and the feeding-out of a tape is stopped without sagging. Accordingly, a conventional brake member and a plunger, etc. are not required, and an apparatus can be made remarkably small in the size and light in weight.

Title: Method of heat accumulation
Inventor: TOMIZAWA TAKESHI
IPC: C09K5/08
Filed: 1988-10-13
Abstract: PURPOSE:To allow a heat accumulation which has a wide range of applications by using an azeotropic mixture comprising a plurality of constituents, water for one, as the operating medium which accumulates heat by making use of a reaction between the operating medium and a chemical substance or the phenomenon of heat absorption and release incidental to the phase change. CONSTITUTION:The heat is accumulated by making use of a chemical reaction. Under the heat accumulation mode, the operating medium 5 and a chemical substance 6 are physically separated from each other by a closed valve 4. Under the heat release mode, the valve 4 is opened to connect both the spaces, whereupon heat is generated, and the temperature up, due to the reaction with the chemical substance 6 in the container B, while, in the container A, the heat is absorbed by the evaporation of the operating medium 5 to cause the temperature to drop. Therefore, up to the point of the completion of the reaction, the coldness is made available on the container A side, and the hot heat on the container B side, for service. For an operating medium 5, an azeotropic mixture comprising water and 2-diethylaminoethanol is used, and, for a chemical substance 6, an active charcoal adsorber is used.
