Title: Agitator
Inventor: KATOU AKIFUMI
IPC: B01J8/38
Filed: 1980-03-24
Abstract: PURPOSE:To obtain the agitator with which the polymerization of olefins and the like can be conducted on an industrial scale and in a continuous manner by providing at least one pair of blades on the inner side of a pair of blades of an anchor type agitator, said at least one pair of blades being orthogonal to the one pair of blades. CONSTITUTION:In the agitator for a fluidized bed used for catalytic polymerization of olefins such as ethylene, propylene, etc., the pair of the blades 5 are supported by a rotary shaft 1 and at least one pair of the blades 7 orthogonal to the blades 5 are supported on the inner side of the blades 5 by the shaft 1 through arms 8. The tip end of each of the blades 5 is acute-angled and has a right-angular cross- sectional shape, so that the fluidized bed performs such a rotational motion as to be raked inwardly, thereby preventing the produced polymer from being deposited onto the wall surface. In addition, since the blades 5, 7 are provided in the manner described above, channeling of the gas due to the formation of a vortex is prevented. Accordingly, the agitator can be operated on the industrial scale for a prolonged period of time.

Title: Intake device for lpg engine
Inventor: MURATA CHITAKE
IPC: F02D19/02
Filed: 1989-02-20
Abstract: PURPOSE:To aim at preventing LPG supply stoppage and improving output by enabling the communication between a carburetor and an inlet into which dynamic pressure is scarcely led when the car speed is more than the set value and the engine load is lower than the set value. CONSTITUTION:When the detection value of a speed sensor 31 is lower than the set value, a solenoid valve 27 is closed by an ECU 30, so that negative pressure is not led into the negative pressure chamber 22 of a negative pressure actuator 19. A change-over valve 20 is changed over into a full line position so as to cut off the communication between an intake pipe 6 and a hot air passage 17 as well as open the intake pipe to its full admission. The atmospheric air inhaled from an inlet 7 is thus led into a carburetor 4. On the other hand, when the car speed is over the set value and load is low, the negative pressure is led into the negative pressure chamber 22 from a port 25 and the change-over valve 20 is changed over into the dotted line position. The intake pipe 6 and the hot air passage 17 are thus communicated, and the communication between the inlet 7 and an air cleaner 3 is cut off, so that the air in an engine room is led into the carburetor 4.

Abstract: PURPOSE:To solve a problem of clogging in a valve stored in a compression piston and improve a compression ratio of working fluid by a method wherein an orifice type valve for use in controlling an intermediate pressure is eliminat ed. CONSTITUTION:A compression piston 23 for compressing working fluid has a first pressure responding relief valve 51 and a second pressure responding relief valve 52 therein. When an actual pressure of a compression chamber 22 is higher than its maximum set pressure, the first pressure relief valve 51 is released and then a surplus pressure in the compression chamber 22 is released to a back pressure spacing 21. When the actual pressure in the compression chamber 22 is lower than its minimum set pressure, the second pressure responding relief valve 52 is released and then a surplus pressure in the back- pressure spacing 21 is supplemented to the compression chamber 22. With such an arrangement, the compression chamber 22 is kept at its appropriate pressure, the back-pressure side spacing 21 is kept at an intermediate pressure between the maximum set pressure and the minimum set pressure of the compression chamber 22 and then the intermediate pressure control can be attained.

Abstract: PURPOSE:To set and reset a semiconductor laser by emitting two types of specific external input lights to the laser, and controlling optical bistable characteristic in the output light properties of the laser to the intensity of the first external input light according to the intensity of the second external input light. CONSTITUTION:An external input light 1 (optical intensity X1) having a wavelength lambda1 (frequency f1) and an external input light 2 (optical intensity X2) having a wavelength lambda2 (frequency f2) are incident to a semiconductor laser 3 to be oscillated with a wavelength lambda0 (frequency f0), and output lights 4-6 (optical intensities (Y0-Y2) corresponding to the wavelengths l0, lambda1 and l0 are obtained as output lights. Here, (f0-f1)<(f0-f2) is satisfied. That is, lights having a longer wavelength than the oscillation wavelength of the laser and different two wavelengths l1, l2 are simultaneously emitted to the laser 3 to control bistability in the light input/output characteristics of the laser. Thus, an optical memory function, a flip-flop operation, etc., can be realized without using a semiconductor laser of a specific structure.

A drain electrode 10 is formed in a position corresponding to the drain 6, and at the same time a second gate electrode 11 connected to a gate signal line G through a contact hole is formed on the interlayer dielectric 9 above the channel 7. This enables the TFT channels to intersect the gate at two or more points, and allows adjoining channels to have current passages in different directions.

Title: Nitride gallium light emitting element
Inventor: OOKI YOSHIMASA
IPC: H01L29/45
Filed: 1981-03-17
Abstract: PURPOSE:To prevent short circuit by solder, by providing metal of high adhesiveness with crystal in the lower layer of more than two layers of LED electrode metal of Ga N, and by laminating a metal of high adhesiveness by solder in smaller area than the lower layer thereby providing a solder bump on the upper layer metal. CONSTITUTION:An electrode 44 on an i type Ga N layer 3 has two layers and the layer 4 is made of metal (Ti) which repels solder but well adheres to crystal surface. The area of the layer 4 is wide enough for the light emitting region of Ga N LED and a solderable metal (Ni) is laminated on the area smaller than the layer 4. It is formed by a preset method at the necessary distance from an electrode connected with an n type Ga N layer 2. There is no need of changing the area of the electrode 55 because it has a small area between the layers 5' and 5''. It may be effective to provide the A layer below the layers 4' and 5' in order to improve adhesiveness to the i type Ga N layer. A chip of this contruction prevents a short circuit by the diffusion of solder flow and increases the ratio of effective light emitting surface to the chip area.

IPC: G05D1/02
Filed: 1986-02-26
Abstract: PURPOSE:To confirm automatically and completely the safety of an automatically governed vehicle AGV over the approximately entire length of its body and to make the vehicle excellent in durability, by providing optical sensors on the same side face of the vehicle body and opposite to the all-direction reflecting screens fixed at the end part opposite to those optical sensors. CONSTITUTION:If no obstacle exists between the reflecting optical sensors 21-24 and all-direction reflecting screens 11-14 opposite those sensors in a drive or stop mode of an AGV, the beams emitted from the light emitting elements of sensors 21-24 are made incident on the screens 11-14 respectively. These incident beams are reflected by those screens and received by the light receiving elements of the sensors 21-24. Thus the output circuit levels of sensors 21-24 have the normal value showing absence of faults. Thus, it is possible to confirm the safety of the AGV automatically and completely over the approximately entire length of the AGV body. In addition, an optical bumper for AGV can be attached with no change of specifications.
