Title: Rotary polygon mirror type optical deflector
Inventor: SUMIHIRO MASAKAZU
IPC: G02B26/10
Filed: 1985-12-25
Abstract: PURPOSE:To simplify the working stage by providing an air reservoir on a thrust pad, and also fluting an oblique groove for making an air-flow flow into this air reservoir, on a fixed shaft. CONSTITUTION:An air-flow flowing into herringbone grooves 6, 6 of a fixed shaft 20 by a rotation of a magnet 10 works on an air-gap G between the outside peripheral surface of the fixed shaft 20 and the inside peripheral surface, as an air dynamic pressure, and supports a revolving shaft 7 in the radial direction. On the other hand, the air-flow flowing into an oblique groove R of the fixed shaft 20 flows into an air reservoir 18 of a thrust pad 17. By this air-flow, an air pressure in the air reservoir 18 becomes high gradually and floats up the revolving shaft 7 in the thrust direction. In this case, by floating of the revolving shaft 7, a face 17a of the thrust pad 17 and a face 19a of a thrust bearing 19 are separated from its contact, and a part of air in the air reservoir 18 flows out, but since the quantity of air flowing into the air reservoir 18 is large, the floating of the revolving shaft 7 can be maintained.

Title: Wave motion transmitting and receiving method
Inventor: NIRASAWA TOMIJI
IPC: G01S7/527
Filed: 1988-11-18
Abstract: PURPOSE:To detect received signals in high probability even if they are the received signals of wave having slow rise-up by providing first and second transmitting and receiving wave portion groups and setting a plurality of transmitting wave portions and receiving wave portions in each transmitting and receiving wave portion group. CONSTITUTION:After two signals which are made reverse phases each other are distributed into a plurality of transmitting and receiving portions 6, 6A by distribution collectors 4, 4A respectively, converted into supersonic waves to transmit and the reflected waves are received by each transmitting and receiving portion 6, 6A, since addition in the distribution collectors 4, 4A, namely, integration is spatially performed, signal amplitude can be increased as the increase of random noises are controlled. Furthermore, since first and second addition signals which are made reverse phases each other are composed, obstructions can be offset each other. Accordingly, even if the rise of the received signals is slow, the ratio of noise to signal can be improved and the detection of the signals is performed in high probability at the pulse beginning.

IPC: G01J3/42
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To measure the reflection factor of a sample quickly without damaging the sample. SOLUTION: A light emitted from a light source 10 is converted into monochromatic light by a monochrometer 12, passed through an incidence window 14A, and is applied to a sample 16, and reflection light from the sample 16 is diffused by an integrating sphere 14, passes through a measurement window 14B, and enters a monochrometer 18. An adjusting device 22 changes the wavelength of monochromatic light over a measurement range, performs control so that a monochromatic light with the same wavelength can be emitted from the monochrometers 12 and 18, and scans a sample surface.  Since the monochrometers 12 and 18 are adjusted so that monochromatic light with the same wavelength can be emitted, so that only the component of monochromatic light being reflected by the sample 16 is emitted from the monochromatic meter 18, thus obtaining the distribution of a reflection factor from a reception signal received from a light receiver 20.

IPC: G02B26/08
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To improve the strength of the surface of the glass base plate having the positioning groove by strengthening the surface of the groove. SOLUTION: A glass material 30 is, for example, alkali glass and a ceramic- mold 40 has an inverted V type rib 42. The softened glass material 30 is pressed against the mold 40 to transfer the shape of the mold 40, and the glass base plate 32 having the V groove 32 is formed. Then the glass base plate 32 is dipped, for example, in alkali compound dissolved liquid 44 to perform a treatment by a low-temperature type chemical strengthening method. Consequently, the glass base plate 32 having the V groove 34 whose surface 340 is strengthened is obtained. Thus, the base plate 32 having the positioning groove 34 for an optical fiber can be mass-produced at a low price since it is made of glass, and the surface 340 of the groove 34 is strengthened, so necessary strength is obtained. Therefore, the V-groove manufacture cost is greatly reduced to obtain a switch device at a low cost.

Abstract: PURPOSE:To facilitate real time processing, and to ensure high recognition rate by calculating the average of the frequency characteristic in each block, by normalizing the average for each correspondent region, and by inputting the value thus obtained into a neural network. CONSTITUTION:The sound waveform of unknown speaker for each word is passed through a 32-channel band pass filter 11, so as to calculate the frequency characteristic of the input sound. Each of the sound interval for which the sound waveform is equally divided into eight in terms of time in each region of the band pass filter 11, forms one block, and the average of the frequency characteristic thus obtained is calculated in each block by an averaging circuit 12.

Title: Slush molding method
Inventor: ODAKA KOICHI
IPC: B29C41/18
Filed: 1991-11-08
Abstract: PURPOSE:To uniformalize the adhesion and fusion of resin to a mold and surely remove excess resin by a method wherein vibration is indirectly given to the mold on or after the adhesion and fusion of powdered resin to the heated mold. CONSTITUTION:A mold 1 is supported by a frame body 4. Powdered molding stock 10 is housed in a powder box 9. Under the condition that the heated mold 1 and the powder box 9 are connected together so as to come into tightly contact with each other, the resultant assembly is turned upside down. Just after the turning, the mold 1 is indirectly vibrated by giving vibration with blowing or the like to the frame body 4. Thus, stock 10 can surely be adhered even to the narrow recessed part 3 of the molding surface of the mold. After that, the resultant assembly is turned again upside down. At this time, the mold 1 is similarly vibrated as before. As a result, excess stock 10 is surely fallen down into the powder box 9. Since the mold 1 is vibrated indirectly, the breakage and lowering of service life of the mold 1 can be prevented from occurring.
