Title: Exhaust emission control device for internal combustion engine
Inventor: IRISAWA YASUYUKI
IPC: F01N13/02
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To raise a control accuracy to the theoretical air fuel ratio of the air fuel ratio of an exhaust gas flowing in a storage reduction type NOX catalyst at SOX release time. SOLUTION: When the temperature of NOX catalyst 12 is increased, first and fourth cylinders are made to a rich cylinder operated by a rich air fuel ratio and second and third cylinders are made to a lean cylinder operated by a lean air fuel ratio. When the air fuel ratio feedback control by a cylinder group for feedback controlling the air fuel ratio is carried out based on the output signal of an upper streamside air fuel ratio sensor 18 provided on the upper stream of NOX catalyst 12, by correcting the feedback target value based on the rich coefficient representing the rich degree of the air fuel ratio in the rich cylinder and air amount, a flow in exhaust average air fuel ratio is controlled to a theoretical air fuel ratio substantially.

Title: Clothing dryer
Inventor: FUJINAKA SHUICHI
IPC: D06F58/28
Filed: 1987-12-14
Abstract: PURPOSE: To simplify the program of a microcomputer by judging how much clothing is dried from the difference of inhale and exhale side temperatures through the microcomputer while using a diode as a temperature sensor. CONSTITUTION: Since the inhale and exhale side temperatures of a drum are equal in the beginning, terminal voltages V1 and V2 of diodes D1 and D2 are equal and the condition of output E1=0 of an operational amplifier OP2 is established. When the drying of clothing is advanced and the exhale side temperature gets higher than the inhale side temperature, the condition of voltage V1>V2 is established and the output E1 is outputted from the operational amplifier OP2. The output E1 is compared with the output E2 of an operational amplifier OP3 by an operational amplifier OP4 and at the time of output E1>E2, the output E3 of the operational amplifier OP4 is changed from High to Low. A microcomputer 1 judges the end of drying of clothing from the change of the output E3. Thus, the program of the microcomputer for controlling operation is simplified.

Title: Lattice code decoding method
Inventor: RIN MOSHO
IPC: H04L27/00
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To design a lattice code that has a long free distance despite the small constraint length of a binary convolutional code by replacing a multi- valued delay processor with a conventional processor via encoding. SOLUTION: A processor P<(2)> decides the branch metric Mυ '(t) for each of 2<m> pieces of encoder outputs υ'(t) based on the received sequence, a transmission function matrix and a symbol that is previously recovered and sends a group TM(t) to a processor P<(1)> . The processor P<(1)> uses a metric sequence as its input and applies the Viterbi algorithm to a lattice C to recover the symbol to be transmitted by resetting the decoding round-down length of the lattice C. Then a lattice code T is obtained by changing the transmission function matrix. Thus, the free distance of the code T is increased via the proper transmission function matrix and the constraint length of the lattice C is reduced.

Title: Bath controlling system in cationic electrodeposition coating
Inventor: MIZUNO SHINJI
IPC: B05D1/18
Filed: 1989-12-08
Abstract: PURPOSE:To keep dispersion stability of electrodeposition bath coating material and to enhance both finishing of coating and electric power efficiency for electrodeposition coating by filtering the electrodeposition bath coating material with a semipermeable membrane and continuously measuring both the amount of filtrate and the specific conductivity of the bath coating material and adding a neutralizer or substituting one part thereof with pure water on the basis of the result of measurement. CONSTITUTION:Electrodeposition bath coating material 2 is introduced into an electrodeposition tank 1. While the material 4 to be coated is hung with a hanger 3 and moved to the direction shown in an arrow, electricity is conducted between a cathode being the material 4 to be coated and an anode 5 in the bath coating material 2. The surface of the material 4 to be coated is subjected to electrodoposition coating and washed by water in the water washing tanks 6, 7 and the bath coating material stuck on the surface is washed with water and removed. The bath coating material is sent to a semipermeable membrane 8 by a circulation pump and filtered. The filtrate 9 is measured with a flowmeter 9'. When the amount thereof is reduced, dispersion stability is impaired and therefore acid of a neutralizer is replenished to enhance dispersion stability of the bath coating material. Further when the specific conductivity of the bath coating material is measured with a measuring instrument 11 and the measured value exceeds the preset value, one part of filtrate 9 filtered from the semipermeable membrane is discharged from a changeover valve 12. Equal amount of pure water is replenished and the specific conductivity is lowered to the preset value. Dispersion stability of the bath coating material is enhanced and electrodeposition coating excellent in finishing properties is performed at little electric power and little bath coating material.

Title: Protective element for document, and its manufacture
Inventor: LANG CHRISTIAN
IPC: B42D15/10
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To improve the copy protection of a document equipped with a protective element by a method wherein for a document equipped with the protective element including a base material and an optical grating, the optical grating is a volume hologram wherein an dynamic effect is introduced. SOLUTION: A dynamic or kinematic effect is introduced to a volume hologram 2, or is written. In order to generate such a dynamic effect, the diffraction structure of the volume hologram 2 is constituted in such a manner that when a base material 1 is moved on the plane, e.g. rotated in a fixed direction at a fixed speed, a pattern which is generated by a fixed radiation and an observation direction, is made movable preferably at a specified speed along a specified path in a coordinate system which has a fixed relationship with the base material 1. By introducing the dynamic effect into the volume hologram 2, a copying of the hologram 2 is made more difficult. In addition, by this method, a higher identification value can be obtained, and individual data can be emitted in the volume hologram 2 by a separate single radiation in the same manner.

IPC: B29K105/06
Filed: 1988-12-16
Abstract: PURPOSE:To completely discharge bubbles in a laminate by a method wherein an elastically deformable pressure plate habing a curved surface shape with a recess at the center is placed so as to face the recessed part upward on the laminate in order to gradually apply vacuum pressure from the central part of the laminate to its peripheral part during vacuumizing. CONSTITUTION:When a space 10 inside a vacuum bag film 7 is vacuumized under the condition that a laminate 3, a pressure plate 9, a breather 6 and the vacuum bag film 7 are piled up in the order named, vacuum pressure is applied through the central recessed portion of the pressure plate 9 to the central part of the laminate 3. As a result, bubbles (a) entrapped at the central part of the laminate 3 start to gradually move to the end part. When vacuum pressure increases, the pressure plate 9 gradually deforms to be flat and the vacuum pressure applying to the laminate 3 becomes to be applied not only to the central part but also the peripheral part, resulting in moving the bubbles (a) in the laminate 3 further to the end part. When vacuum pressure increases further, the pressure plate 9 becomes completely flat and the vacuum pressure reaches the whole region of the laminate 3, resulting in completely discharging the bubbles (a) out of the end part.
