Title: Digital signal recording and reproducing device
Inventor: OKADA HIROSHI
IPC: G11B20/12
Filed: 1991-07-12
Abstract: PURPOSE:To keep the interchangeability with a digital audio equipment, which has a different bit rate, with a simple constitution and simultaneously improve the error correcting capability during a reproduction. CONSTITUTION:For a non-standard digital audio data, a previously known data '0' are added to configure a standard frame, here k1Xk2X=26X28 (bytes). To this, parities P1 and P2 are added to configure a standard multiplication sign configuration n1Xn2=32X32 (bytes). Then, an interleaving takes place on this so that the previously known data '0' are inlayed in the audio data and are recorded thus, audio with a different bit rate are recorded. During a reproduction, the previously known data '0' are inserted into the same position of the recording then, an error correction takes place. By this arrangement, when an error is generated in the previously known data '0', this is returned to '0' thus, the number of errors is reduced. Thus, error correcting capability is improved after the above process.

Title: Magneto-optical recording and reproducing device
Inventor: WATANABE SATORU
IPC: G11B7/09
Filed: 1990-07-02
Abstract: PURPOSE:To prevent the occurrence of out-of-focus even at the time of recording by means of an optical disk by detecting an offset signal from a focus error signal at the time of trying writing by means of a sector mark and supplying the difference signal of the offset signal outputted from regular reproduction time as the offset signal at the time of recording. CONSTITUTION:A first sample-hold circuit 18 detecting the focus error signal when an area for the trial of writing provided on a part of the sector mark of a magneto-optical disk D is irradiated with laser beam and a second sample- hold circuit 19 detecting the offset signal of the focus error signal outputted at the time of reproduction are provided. At the time of recording in the data area, a value obtained by subtracting the output of the second sample-hold circuit 19 from the output of the first sample-hold circuit 18 is inputted as the offset voltage of the focus servo circuit. Thus, a focus which comes to one even in the period when the focus error signal is sample-held is subjected to servo and out-of-focus occurring at the time of recording can be cancelled.

Inventor: HASEGAWA OSAMU
IPC: H01L21/208
Filed: 1979-12-28
Abstract: PURPOSE:To increase the directivity by providing a light emitting part in the part (with a small x value) of Ga1-xAlxAs which has a semicircular cross sectional area and whose x value gradually decreases, and taking out light from the side of the semicircular shape. CONSTITUTION:An Al2O3 mask 3 is provided on a GaAs substrate 1. Etching is performed by phosphoric acid series liquid having no directivity, a semicircular groove is provided in a substrate 1, and Ga1-xAlxAs 2 is grown by the liquid phase epitaxial growth. In this case, since the distribution of the x values (equal refractive index distribution) is slightly shifted from the center, a reflecting film 4 is provided in the vicinity of the light emitting part. In forming the layer 2, the x value in Ga1-xAlxAs, which is grown by utilizing the difference in segregation factors of AlAs and GaAs, is gradually decreased, and the light emitting part is provided in the part with the small x value. In this constitution, the light is bent depending on the variation in the x value, becomes parallel with the crystal face, and is never  deviated from the system before it is emitted from the light emitting surface. Therefore the directivity can be improved.

Title: Fluidized bed boiler control device
Inventor: SONODA TAKASHI
IPC: F22B1/02
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To control the temperature of steam with high reliability by receiving a spray flow-rate command signal and providing a correction control means which receives the output of an subtracter and outputs a correction signal to an adding machine, when the signal is below a specified value. SOLUTION: An output is transmitted to an analog switch 12 with a subtracter 05. The output of the subtracter 05 is transmitted as a spray flow-rate command signal 09 by way of a controller 06, a subtracter 07 and a controller 08. The output of the controller 08 is transmitted to the analog switch 12 by way of an elevation monitor 11. The output of a constant generator 13 is transmitted to the analog switch 12 where the output of the analog switch 12 is transmitted to an adding machine 15 by way of a correction controller 14. When the spray flow rate command signal 09 is reduced to a specified value or below, the output of the subtracter 05 is transmitted from the analog switch 12. The output signal of the analog switch 21 becomes a correction signal by way of the correction controller 14 (for example, proportional controller).  This construction makes it possible to maintain a specified value for the output steam temperature of a superheater.

Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent fluctuation in a luminous quantity of a transmitted or reflected light in a read area (read width) read by a solid-state image pickup element even when an emitting position of a slit light is deviated due to vibration when image reading. SOLUTION: Left and right reflectors divided into two are placed, respective first foci are identical (location of a halogen lamp) and respective 2nd foci are separated to the left and right from a center of a lighting area. The positions of the foci are expressed in terms of luminous quantity distribution to obtain characteristics shown in solid lines in a selected Fig. (chain lines depict a conventional method). That is, the width with nearly uniform luminous quantity is about a multiple of 1.5 of that of a CCD line sensor and a ratio of a minimum luminous quantity to a maximum luminous quantity within the range is about 80%. The two reflectors are adopted to have respectively different 2nd foci, thus a read error resulting from vibration is suppressed.

For this another slicing selective excitation, a coincidence of amt. of application of inclined magnetic fields before and after the standard time is attempted. On each sliced face, a phase diffusion and a readjustment of the phase are completely performed thereby and acquisition of echo can be surely performed.

Title: Wavelength multiplex light emitting and light receiving devices
Inventor: MATSUDA KENICHI
IPC: H01L31/0232
Filed: 1994-07-26
Abstract: PURPOSE:To provide a wavelength multiplex light emitting and light receiving devices which can ensure the coincidence of wavelenghs between the transmission and reception sides by controlling the relative wavelength to the wavelength of the standard light. CONSTITUTION:Plural light emitting elements 102 of different light emitting wavelengths are included in a light emitting element array 101. The radiant light beams 105 are led into a signal light fiber 108 via the branch fibers 106. The radiant terminal of a reference light fiber 109 which constructs a double core fiber with the fiber 108 is connected to a wavelength comparator 110. The beam 105 radiated from a correction light emitting element 111 is also made incident on the comparator 110. The comparator 110 outputs an electric signal proportional to the difference of wavelengths between the beam 105 and the beam radiated from the fiber 109 to a drive circuit 113. The circuit 113 changes the drive current of a temperature control element 104 in response to the input signal received from the comparator 110. Thus the temperature of the array 101 varies and therefore the light emitting wavelengths of both elements 111 and 102 are changed.

Title: Photographic film cartridge
Inventor: ENOMOTO MASAHIRO
IPC: G03C3/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce offensive noise caused when a photographic film is rewound in a photographic film cartridge. SOLUTION: A vibration suppressing rib 70 brought into contact with the vicinity of the edge of the photographic film 6 rubbing the edge of a lip 17a is formed at the inside wall of an upper case 3. The rib 70 is formed so as to be higher as much as difference H1 than a film pressing rib 50 which is formed at the inside wall of the case 3 near a film gateway 10 and which supports the film 6 from the back surface side and prevents it from being brought into contact with the inside wall of the case 3 and so as to be positioned more inside than the rib 50 in a cartridge main body 5. When the film 6 fed out from the gateway 10 once is rewound, the film 6 is apt to be vibrated because it strongly rubs the edge of the lip 17a. However, since the rib 70 is brought into contact with the film 6, the vibration of the film 6 is suppressed.  Thus, the noise caused by the vibration of the film 6 is reduced.
