Title: Emission control device for internal combustion engine
Inventor: HIROTA SHINYA
IPC: F01N3/08
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To perform excellent purification of NOX by a method wherein NOX is temporarily stored in a storage material and by discharging the stored NOX, NH3 is produced from NOX, SOLUTION: The cylinders of an internal combustion engine are divided into first and second cylinder groups 1a and 1b and the first cylinder group 1a is further divided into first and second auxiliary cylinder groups 1aa and 1ab. NOX storage reduction catalysts 12a and 12b are arranged in the exhaust branch pipes 8 of the auxiliary cylinder groups 1aa and 1ab, respectively. The NOX storage reduction catalysts 12a and 12b and the second cylinder group 1b are brought into a state to be confluent with each other and to connect it to an emission control catalyst 10. By enriching an exhaust air-fuel ratio of exhaust gas, flowing in the NOX storage reduction catalyst 12a, NOX is discharged to produce NH3 . The NH3 purifies NOX discharged from the second cylinder group 1b in the emission control catalyst 10.  By bringing an exhaust air-fuel ratio of exhaust gas, flowing in the storage reduction catalyst 12b, into a lean state, NOX is stored. When a storage NOX amount of the NOX storage reduction catalyst 12a is reduced to a value lower than a lower limit threshold, an exhaust air-fuel ratio of exhaust gas flowing in the storage reduction catalysts 12a and 12b are brought into a lean and a rich state, respectively.

Abstract: PURPOSE:To enable automation of sampling operation and feeding of a sample container to a conveyance pipe, by using a container with a cap with a reduced pressure inside as a sampling container and a conveying container to put an injection needle into the cap. CONSTITUTION:A sampling tube 2 is mounted on a process pipe 1 to place a liquid therein 1 into the pipe 2. An electromagnetic valve 21 is interposed in the course of the pipe 2 to adjust the outflow and stoppage of a sampling liquid and an injection needle 22 is mounted at the tip of the pipe 2. Moreover, a holder 2 for holding the injection needle 22 slides with the action of a cylinder 25 on a guide plate 24 and a piston rod thereof. After the injection needle 22 runs through a rubber cap 28, the electromagnetic valve 21 is opened.

Title: Bias circuit for field effect transistor
Inventor: SAIKAI TOSHIO
IPC: H03G3/10
Filed: 1987-08-20
Abstract: PURPOSE:To form a bias circuit by one power source, by supplying a voltage voltage-divided by a bleeder resistor connected to the source of a dual gate FET to a first gate, and impressing the voltage having the same polarity as that of a drain voltage and lower than a source voltage on a second gate. CONSTITUTION:By impressing a positive voltage +V on a drain voltage terminal 2, the voltage in which the source voltage is voltage-divided by resistors 7 and 8 is impressed on a first gate voltage terminal 3. Therefore, a bias voltage set as a negative voltage relatively compared with the source voltage is supplied to the first gate. Also, the positive voltage set as a negative one relatively for the source voltage is supplied to a second gate voltage terminal 4. Consequently, by supplying the negative voltage to the first gate by self-biasing, and impressing a relatively negative voltage on the second gate, it is possible to realize the gain control of a FET amplifier by a single positive voltage source.

Title: Phase jump prevention system for cbr signal
Inventor: UCHIDA KAZUHIRO
IPC: H04L12/66
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To prevent a phase jump by switching only a pointer value to a last frame value when a discarded cell includes a pointer. SOLUTION: A pointer process means 5 extracts a pointer indicating the head position of the frame phase included in a read CBR signal according to a pointer value instructed by a cell pointer process means 4 and the read phase of the CBR signal from a buffer means 1 is controlled. At this time, a last pointer holding means 6 also inputs and holds the same pointer and further holds the last received pointer at the same time, thereby generating the pointer of the last frame from its output side. Then a switching means 7 selects and outputs the signal passed through the pointer process means 5 except the pointer value of the CBR signal to an SDH network, but when the output of an SN process means 2 displays cell discarding as to the signal at the instructed pointer position, switching is so performed as to select the last pointer.  When the cell discarding is not generated, on the other hand, the pointer outputted from the pointer process means 5 is selected.

Title: Friction welding method
Inventor: SAKAMOTO TATSUYA
IPC: B23K20/12
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a high joining strength of works by holding at a constant value a relative revolving speed and a pressing speed between the works, stopping the relative revolving speed at a prescribed reduction ratio subsequently, and stopping the pressing after the revolution stoppage. SOLUTION: Friction welding is performed while a prescribed value is held constant in the relative revolution speed Na and the pressing speed Va between works. With the relative revolution speed Na reduced at a prescribed reduction ratio, time is controlled from the formation point of plastic flow to the stop point of the relative revolution between the works. Since the inter-work pressing speed between these points is held at Va, the upset length can be controlled. At the stop point of the inter-work relative revolution where the relative revolving speed Na becomes zero between the works, the inter-work pressing speed Va can be reduced nearly instantly at the prescribed reduction ratio.  The time to stop the relative revolution of the works is judged from the presence/absence of the formation of the plastic flow layer, with the friction welding carried out in accordance with the softened state of the abutting faces; hence, a product is obtained having little variation in dimensions.
