Title: Wavelength variable light device
Inventor: UCHIDA MAMORU
IPC: H01S5/12
Filed: 1991-03-12
Abstract: PURPOSE:To enable a new wavelength variable light device for a high-density wavelength multiple light communication system etc., to be produced inexpensively. CONSTITUTION:A title item is a wavelength variable light device such as a wavelength variable semiconductor laser and a wavelength variable filter which can be oscillated at a plurality of relatively isolated (for example, several tens of nm) wavelength regions and further has a variable width which is approximately several tens of Angstrom  at each oscillation wavelength region. An activation layer 13 which is formed on a substrate 11 is, for example, in an asymmetrical quantum well structure, and the gain spectrum has a plurality of maximum values. Therefore, a resonator with a multilayer structure including an activation layer 13 as an optical waveguide has a configuration so that the loss spectrum has a plurality of minimum values corresponding to the maximum value of the above gain spectrum by forming a grating structure 17 which is made by superposing corrugations with a plurality of pitches. By controlling an injection carrier density to an electrode 18, a relative relationship of a plurality of maximum values of the gain spectrum and the minimum value peak position of the loss spectrum can be varied.

Title: Grid structure
Inventor: OKADA MIZUO
IPC: E06B9/01
Filed: 1993-03-30
Abstract: PURPOSE:To prevent a frame in grid structure from falling off. CONSTITUTION:Frames 10, which cross each other, provide main frames 11a to 13a, which extend in one direction, and reinforcing frames 11b to 13b, which are joined in a laminated state. These main frames 11a to 13a and the reinforcing frame 11b to 13b are alternately placed one upon the other under three layer structure and joined. The main frames 11a to 13a are adapted to cross adjacent main frames. Since each layer's main frame is crossed, the main frames in the uppermost outside layer are joined with the reinforcing frames respectively so that the main frames in the central part are clamped with the frames in the uppermost outer layer. This construction makes it possible to prevent each layer's main frame from coming off and each frame from coming off since the reinforcing frames are joined with the main frames.

Title: Carbon fiber/carbon composite material and production thereof
Inventor: AIBA YASUHIRO
IPC: C04B35/83
Filed: 1990-03-22
Abstract: PURPOSE:To obtain a C/C composite material hardly able to be cut and having high strength comprising interior matrix in fiber bundle of carbon fibers mainly made of carbon derived from carbonization of pitch and matrix between the bundles made of carbon containing glassy carbon. CONSTITUTION:Breakage of carbon fiber is prevented by impregnating with pitch hardly shrinking in carbonization and matrix of the fiber is formed in fiber bundle, then the matrix is reinforced. On the other hand, pitch has a disadvantage of melting in carbonization and flowing out with decreasing of viscosity, therefore thermosetting resin having no fear of flowing out in carbonization is used at least one time in impregnating carbonization treatments on and after second time. By said processes, gaps between fiber bundles are filled with carbon containing glassy carbon derived from carbonization of thermosetting resin. Therefore, matrix mainly composed of carbon derived from heat treatment of pitch is formed in the fiber bundle and a relatively large amount of matrix containing glassy carbon is formed between fiber bundles without damaging the carbon fibers, then strength of the C/C composite material is improved.

Title: Method and apparatus for detecting continuous fine waviness
Inventor: MASUDA KENJI
IPC: G01B11/30
Filed: 1990-03-22
Abstract: PURPOSE:To secure evaluation by a method wherein a surface to be inspected is irradiated with parallel light to detect a distribution of spatial secondary brightness variation distribution of the reflected light thereof and a brightness variation signal thus obtained is compressed in one way to make a primary brightness variation signal and a distribution state of brightness variation is checked with an arithmetic process so to detect the presence of any continuous fine waviness of a steel sheet or the like from the results. CONSTITUTION:When a steel sheet 1 as object to be inspected is advanced in a direction of the arrow, a stripe pattern (chattering mark) 1a is generated on the surface thereof in a direction of a line. So, the surface of the steel sheet is irradiated with parallel light from a parallel light irradiator 2 to detect a spatial secondary distribution of the parallel light reflected with a primary brightness variation signal detector 3 and the results are compressed in one way to make a primary brightness variation signal. Then, a distribution of the primary brightness signal obtained previously with an arithmetic processor 4 is checked to evaluate the presence of any continuous fine waviness on the surface of the steel sheet 1. Thus, it is possible to detect fine waviness non-contact, continuously and automatically at a high accuracy thereby making it ideal for inspection on a production line.

Filed: 1993-03-31
Abstract: PURPOSE:To effect recirculation air conditioning, partial return air conditioning and total outside air conditioning by appropriately controlling an outside air damper, an exhaust air damper and a return air damper. CONSTITUTION:By closing an outside air damper OD and an exhaust air damper ED and opening a return damper RD, recirculation air conditioning is effected in which the whole volume of return air from an air conditioned zone is conditioned and supplied to the air conditioned zone again.

Title: Data demodulator
Inventor: AKAHORI HIROTSUGU
IPC: H04B1/10
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To improve correction accuracy by comparing a coded signal with a bit error discrimination signal so as to locate a bit having a bit error in a 1st digital signal depending on the result of comparison thereby strictly locating the bit with an error. SOLUTION: A mixer 66 mixes an intermediate frequency signal S1 being an output of a band-pass filter 4 with an output S5 of a mixer 65 to conduct spread demodulation. A band-pass filter 67 eliminates only a coded processing signal component whose frequency band is a half that of a received wave from a noise component spread by the mixer 66. A discrimination circuit 68 demodulates an output of the band-pass filter 67 into digital data. A correction circuit 69 receives both a discrimination result outputted from the discrimination circuit 68 and a code processing signal S3, compares them and discriminates the absence of mis-discrimination when the both are coincident.  On the other hand, when the both are dissident, the correction circuit 69 discriminates the presence of mis-discrimination at a dissident position and inverts a corresponding bit of an output of a discrimination circuit 5 received via a delay circuit 62 and provides an output of the result.

Title: Cyclone separator
Inventor: TAKAHARA SHIGERU
IPC: B04C5/08
Filed: 1979-06-11
Abstract: PURPOSE: To increase separating efficiency for particles, by letting particles, separated from fluid which has flowed into the inner cylinder of a double-cylinder cyclone because of its revolving flow, pass to the outer cylinder side through a number of holes made in whole wall of the inner cylinder thereby preventing the particles from returning to the ascending flow of the fluid at the central part of the inner cylinder.  
     CONSTITUTION: A fluid having been introduced 2 into the inner cylinder 1a flows downward helically along the wall surface, then it turns round and rises through the central part of the inner cylinder 1a, at last it is discharged 3. Particles suspended in the fluid are collected to the wall surface of the inner cylinder 1a by the centrifugal force during the helical motion of the fluid, and is passed through a number of holes 6 made in the wall to the outer cylinder 1b. The particles descends along the wall surface of the outer cylinder 1b, then discharged 4, while particles having not passed through the holes 6 are dropped through an aperture 5 and are discharged 4 in a similar way. As a result, a large portion of the particles in the fluid pass through the holes 6 made in the wall of the inner cylinder 1a and separate from the ascending flow of the fluid in the inner cylinder 1a, hence the carry over of the particles is decreased and the separating efficiency of the cyclone separator is increased.
