Title: Buffer circuit using mos transistor
Inventor: KOBORI YASUNORI
IPC: H03K19/0952
Filed: 1982-08-16
Abstract: PURPOSE:To reduce the transmission distortion of an alternating signal, by making a drain current of an MOS transistor(TR) pair equal, and further making a drain-source voltage equal so as to transmit accurately the DC level independently of an input signal level. CONSTITUTION:A drain current of the MOS TR1 and an emitter current of a TR6, and a drain current of an MOSTR2 and an emitter current of a TR7 are equal respectively, and these current values are denoted respectively I1 and I2. An output voltage VOUT is equal to the sum of an input voltage VIN, a gatesource voltage VGS1 of the TR1, and a base-emitter voltage VBE6 of the TR6 subtracted by a base-emitter voltage VBE7 of the TR7 and a gate-source voltage VSG2 of the TR2. A current value I6 of a current source 8 is almost equal to the I1 and the I1 is nearly equal to the I2, because of the relation of a current value 2I0 of a current source 9, 2I0=I1+I2 I0+I2. Thus, the drain-source voltage of the TRs 1, 2 is almost equal because of the relation of VBE6approx.=VBBE7, resulting that the relations of VGS1 VGS2, and VOUT VIN are obtained. Since the temperature characteristic of the TRs 1, 2 is equal, no temperature drift takes place.

Title: Manufacture of fiber board
Inventor: MOMIYAMA HISAO
IPC: D21J1/14
Filed: 1985-06-27
Abstract: PURPOSE:To contrive space saving and time saving of both cooling and moisture/conditioning lines, by performing the moisture conditioning by spreading or applying water to one side or both the sides of a fiber board at a desired stage after completion of the final heating process. CONSTITUTION:While a post-molding fiber board is being kept at a high temperature water is spread or applied to one side or both the sides of the same. In case of spraying, though the smaller droplets are, the more cooling and moisture conditioning can be performed uniformly, cooling time becomes longer, therefore, a necessary space becomes larger and they are apt to be driven upward through generation of vapor. Therefore, as for the spraying, it is better to be performed by facing toward the upper part form the lower part. In case the droplets are large in size it is better to spray strongly to such an extent that the droplets are broken through colliding force and the uniform cooling and moisture conditioning are performed by making a spraying direction oscillate. As the water is vaporized instantly and the fiber board is deprived of evaporation heat at that instance, the cooling is performed rapidly and the fiber board to which the moisture conditioning has been adjusted at equilibrium moisture content with the air is produced efficiently.

Abstract: PURPOSE: To make the uncoiler unnecessary, and to shorten the time of preparation for interchanging the coiled material in the multiform minor production, by installing the cutter near the uncoiler, and by cutting the coil after uncoiling the coil into the specified loop shape.  
     CONSTITUTION: The desired number of products is taken as (n 1 ); the number of products, to be obtained from the uncoiled material ranging from the cutter 3 to the inlet of the die under the condition that the phototube 2a of the loop controller 2 detects the lowermost trough of the loop of the uncoiled material, is taken as (n 2 ); the press machine is stopped at the point that the (n 1 -n 2 ) products are produced. Next, the coil is uncoiled until the phototube 2a detects the lowermost trough of the loop. Under this condition, the residual amount of the coiled material is examined; if the residual amount is more than a specified amount, the cutter 3 is driven to cut the uncoiled material, and the operation of the press machine is restarted uninterruptedly. If the residual amount is less than the specified amount, the operation of the press machine is restarted without cutting the uncoiled material. According to this system, the recoiling of the coiled material becomes unnecessary, and the productivity is improved.

Title: Oxide superconductor
Inventor: INOMATA KOICHIRO
IPC: C01G1/00
Filed: 1987-06-08
Abstract: PURPOSE:To contrive improvement in density, by partially replacing Cu with Mn in an oxide superconductor containing an Ln element (Y, La, Sc, etc.), Ba and Cu at a specific ratio. CONSTITUTION:In an oxide superconductor containing an Ln element (one or more of Y, La, Sc, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu), Ba and Cu at substantially 1:2:3 atomic ratio, the Cu is partially replaced with Mn. Thereby a high density can be attained and critical current density can be improved. Although replacement with a small amount of Mn exhibits effects thereof, >=0.01atom.% is preferably added for practical use. Although the amount of replacement can be suitably set within a range so as not to deteriorate superconductivity characteristics, an excessively large amount of replacement deteriorates the superconductivity characteristics. Thereby about <=20atom.% is preferred for the practical use.

Title: Image pickup device and method and device for white balance adjustment
Inventor: TAKAHASHI KIMIHARU
IPC: H04N9/04
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To properly adjust white balance even for an image obtained by photographing an object under a fluorescent light. SOLUTION: A digital camera 1 is provided with a CL sensor having a spectral sensitivity at a wavelength band between B and G where the spectral energy of a fluorescent light is smaller in comparison with that of other wavelength bands in addition to B, G, R sensors. A B signal is modulated in response to an absolute value of a difference between the B signal and an CL signal obtained by photographing an object by the digital camera 1. The sensitivity of the signal B is deficient in the spectral energy of the fluorescent light, the value of the modulated B signal is larger than the value of the original B signal by modulating the B signal in response to the absolute value of the difference between the B signal and the CL signal.  Thus, the white balance is adjusted by using the modulated B signal, the G signal and the modulated R signal to properly adjust the white balance by compensating the deficient B sensitivity even in the case that the object is photographed under the fluorescent light.
