Title: Contact member for water purification
Inventor: FURUTA SHINICHI
IPC: C02F3/10
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To impart high treatment capacity and to stabilize treatment capacity even if the flow velocity in sewage treatment is relatively high by constituting a water purifying contact member of a three-dimensional fabric and forming a cylindrical space part in parallel to the flow direction of treated water. SOLUTION: A three-dimensional fabric 12 is obtained by the heat treatment of a fabric woven as a warp-double/weft-triple multiple fabric and formed so that the cylindrical space part 14 having an almost circular cross section thereof is parallel to a warp yarn direction. Since the surface layer 16 and rear layer 18 of the fabric 12 have a shape hard to deform against the deforming stress from the outside. The columnar space parts 14 surrounded by the surface and rear layers 16, 18 stably function as treated water passages. Since the intervals between warp yarns in the surface and rear layers 16, 18 are set so as to hold gaps having a proper size, a part of treated water passes through the surface and rear layers 16, 18 to be introduced into and discharged from the cylindrical space parts 14. When the cylindrical space parts 14 are attached in parallel to the flow direction of treated water, sewage is purified by active bacteria during the passage through the cylindrical space parts 14 and the space parts formed between the adjacent three-dimensional fabrics 12.

Title: Double feed detecting circuit
Inventor: INUYAMA SEIJI
IPC: G06K13/067
Filed: 1980-05-13
Abstract: PURPOSE:To eliminate erroneous discrimination even if characters and symbols are entered in a double field detection surface, by averaging integral values of the quantities of photodetection and comparing the same with a reference value for the discrimination. CONSTITUTION:A form 2 from a hopper 1, while carried to a read head 9 by a transport part 4, passes through a double feed sensor 7. The output Sin of the sensor 7 is inputted to an AD converter 12 and a comparator 17. An AD-converted signal is supplied from a register 13 to an adder 14. An addition clock CL' is obtained by supplying an ON signal as a trigger signal to a multivibrator 23 when the detection signal Sin decreases below 50% of a signal input at the time when there is no form through the comparator 17. The output of the adder 14 is applied from a register 15 to a divider 30, where it is divided by the frequency of addition to output the result to a comparator 32 as an average detection signal value. The comparator 32 compares it with a reference level and, when the input is lower than the reference level, generates a double feed signal.

Title: Semiconductor laser device
Inventor: KARAKIDA SHOICHI
IPC: H01S5/00
Filed: 1989-03-14
Abstract: PURPOSE:To improve heat dissipation in a laser element and contrive improvement in characteristics by causing a diatomic compound semiconductor to be formed into a multilayer laminated structure as a clad layer in such a manner that it is laminated by two kinds of thin films that are 100Angstrom  or less and further, making the laminating interface of a compound semiconductor layer intersect perpendicularly to an active layer face each other. CONSTITUTION:A superlattice structure consisting of AlAs and GaAs is constructed by a lower clad layer 3 and an AlAs barrier layer 4 which is used for confining carriers having a low thermal resistance so that a laminating interface is perpendicularly to an active layer face. A diatomic compound semiconductor is allowed to be formed into a multilayer laminated structure as a clad layer 3 in such a manner it is laminated by two kinds of thin films that are 100Angstrom  or less and further, the laminating interface of a compound semiconductor layer is made to intersect perpendicularly to the active layer face each other. Consequently, laser oscillations cause heat that is generated in the vicinity of an AlGaAs active layer to be transmitted from a GaAs layer 1 to a submount without being affected by a contact thermal resistance and it is dissipated. A semiconductor laser device that is free from a contact resistance in an interface and has the clad layer in which a thermal resistance is low is thus obtained.

IPC: H01L21/822
Filed: 1983-04-11
Abstract: PURPOSE:To complete oxidation in a short time at a low temperature and reduce the leakage current of a Ta film by a method wherein the Ta film is oxidized in high pressure oxygen at a low temperature, and an Si nitride film is adhesion-formed between the Ta film and an Si substrate. CONSTITUTION:An Si nitride film 2 is formed on the surface of an Si semiconductor substrate 1. Next, the Ta film 3 is formed on the film 2. Then, this structure is heat-treated in the atmosphere of high pressure oxygen at a low temperature of 600 deg.C or less, thus converting the film 3 all into a Ta oxide film 4. An electrode 5 is formed on such films 2 and 4. The oxidation of the Ta film can be completed in a short time at a low temperature by forming the capacitor by such a method. Since the film 2 exists between the film 4 and the substrate 1, the interaction between the film 4 and the substrate 1 is blocked, enabling to prevent the formation of Ta silicide having conductivity, and accordingly the leakage current can be reduced.

Title: Heat generating head, its manufacture and recording apparatus using the same
Inventor: TSUMURA MAKOTO
IPC: B41J2/375
Filed: 1989-03-17
Abstract: PURPOSE:To achieve very fine, improved recording with half tone by providing a plurality of common electrodes passing through a band of heat generating resistance bodies in a widthwise direction and a plurality of signal electrodes so arranged as to be in touch with said heat generating resistance bodies and, constituting so that at least one of said electrodes is in touch with a high resistance area. CONSTITUTION:A heat generating head having a switch and a driving circuit is controlled by providing a high resistance area 9 adjacent to a heat generating resistance body portion. When an output of a driving element of the driving circuit 8, for example, Q1 is turned ON, a current 7 runs through a common electrode 2 and an electrode 8a from a power source 3 to a heat generating resistance body 5a, resulting in generation of heat from the body 5a. However, since a current passage between a pair of the electrodes 8a and 8b is shut by the high resistance area 9, no current flows to a heat generating resistance body 5b. Moreover, the minimum distance of the electrodes whereby a high resistance can be achieved is enough for the width of the high resistance area 9. The area of the portions not generating heat is considerably small for an entire head, thereby obtaining a sufficiently high value of the saturation density. Since the head is constituted of units of the common electrode 8b, heat generating resistance body 5a and high resistance area 9, the pitch of picture elements and transmitting system of heat are made the same for all of the heat generating resistance bodies.

Abstract: PURPOSE:To reduce the burden of an operator by providing sensors to detect the presence/absence of merchandise at the starting and ending edges of a carry-in belt conveyer and controlling the carry-in belt conveyer based on the outputs of the both sensors. CONSTITUTION:In the state of stopping a carry-in belt conveyer 11, when a customer comes to a checkout position and successively loads the merchandise taken out from the inside of a cart for shopping onto the merchandise loading position of the conveyer 11 one by one, a sensor SA is turned on.

When the merchandise is carried into a reader part 20 and the sensor SB is changed from OFF to ON, the conveyer 11 is stopped. Next, when the operator picks the merchandise up at the reader part 20, the sensor SB is turned off and the conveyer 11 is restarted. Therefore, the merchandise is carried one by one and stopped in front of a scanner 21, it is not necessary for the operator to pay attention onto the activation of the conveyer 11 and the burden is reduced.
