Title: Reinforced plastic-made propeller
Inventor: NAKAJIMA MINORU
IPC: B63H1/14
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To suppress cavitation, enhance corrosion resistance, and simultaneously provide high strength, light weight and high efficiency, by manufacturing a propeller with reinforced plastic reinforced by fiber. SOLUTION: A propeller 10 is manufactured with reinforced plastic reinforced by fiber serving as raw material. This fiber is preferably carbon fiber. The carbon fiber is oriented in the parallel direction to a skew line S. Since this propeller 10 has the material in high strength, blade thickness can be thinned, and efficiency of the propeller can be improved. Because of small specific gravity, weight can be lightened, inertia moment is decreased, and acceleration performance of a propeller shaft can be enhanced. Further, since the carbon fiber is oriented in the parallel direction to the skew line S, resistance to force tending to bend a blade is strong, resistance to twisting force is not so strong, since changing of a pitch due to resistance of water is relatively easy, and cavitation can be suppressed.

Title: Evaporated fuel disposing device
Inventor: HOKU TAKASHI
IPC: B60K15/01
Filed: 1985-06-08
Abstract: PURPOSE:To make it possible to form a second canister communicated with a fuel tank, in a small capacity size, in a vehicle engine or the like, by providing a control valve which is opened during fuel feed but closed in an evaporated fuel purge condition, in the communication passage between first and second canisters. CONSTITUTION:When fuel feed is initiated after a filter lid 21 is opened, a switch S1 detects fed fuel, and a control circuit 30 changes over a three-way solenoid selector valve 10 between the position (a) and the position (b) to communicate a second canister 8 with a fuel tank 1 and opens a control valve 11 to communicate first and second canisters 3, 8 therebetween. At this time no intake-air vacuum is effected, both purge valves 5, 15 are closed so that evaporated fuel generated during fuel feed is lead and trapped into the first canister 3 when it exceeds the trap capacity of the second canister 8. With this arrangement there is no necessity of providing a relatively large capacity second canister.

Title: Facsimile equipment
Inventor: NEGISHI IWAO
IPC: H04N1/00
Filed: 1987-05-20
Abstract: PURPOSE:To quickly discover abnormality by providing an abnormality writing detecting means to load an interruption to a processor when control information does not belong to a code division set to permit the writing to a special area at the time of writing the control information. CONSTITUTION:When a microprocessor executes the writing to a main memory part, a decoder 5 generates a signal to show whether or not the given address belongs to the area to permit the writing of the main memory part and this is sent to the decoder 52. A decoder 51 generates a signal to show whether or not the given data belongs to the code division to permit the writing and sends it to the decoder 52. The decoder 52 generates 0 when the combination of the signal incoming from decoders 50 and 51 is a writting permitted pattern, generates 1 when it is not the pattern and sends it to an interruption control circuit 53. The circuit 53, when a writing command signal is generated, sends an interrupting signal to a microprocessor when the output of the decoder 52 is 1 and for example, an abnormality generating display is executed.

Abstract: PURPOSE:To prevent looseness and slippage of a hemming part, and to reduce the number of processes and the equipment, by forming a hemming part by wrapping the edge part of one plate material by the edge part of the other plate material, and deforming a part of this hemming part. CONSTITUTION:In a pair of plate materials 1, 2 to be assembled to each other, the edge part of one plate material 1 is bent like L and becomes a flange part 3. The edge part of the other plate material 2 is bent like L, also its tip side is turned back by 180 deg. in the opposite direction and becomes a bended edge part 4. The flange part 3 is wrapped in by the bended edge part 4, and a hemming part 5 is formed. Subsequently, a rectangular deformed part 6 is formed by deforming a prescribed part of the hemming part 5 in the plate thickness direction. Since the deformed part 6 is rectangular, its border line turns toward the direction being orthogonal to an end edge 8 of the hemming part 5. In this way, each plate material 1, 2 causes no looseness nor slippage.

Title: Method for managing state between devices connected through line, data gathering and distributing device, and data communication system
Inventor: ISHIKAWA KOJI
IPC: H04L69/40
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To give no trouble to an opposite-side device at the time of switching from an on-line state to an off-line state by deciding whether or not abnormality occurs, and informing the other device that the operation state of this device is changed when no abnormality is found and changing the operation state on condition that this notice is given. SOLUTION: The data gathering and distributing device A generates and sends a test packet to a data gathering and distributing device B (S101) and starts counting by a timer (S102). When the line connecting the data gathering and distributing devices A and B is not abnormal, return transmission to the data gathering and distributing device A is performed within a prescribed time (S103). When the time up to reception is within the prescribed time, it is decided that the data gathering and collecting device B and the line in use are normal (S104). That is reported to a system management part. The system management part once informed that all lines are completely closed switches the operation state from the on-line state to the off-line state.

IPC: H01J1/304
Filed: 1990-05-17
Abstract: PURPOSE:To perform electron emission stably for a long period of time by colliding a part of the electron omitted from an emitter of another emitter which is not in an emission condition, so as to perform cleaning of the emitter. CONSTITUTION:When an electron e1 is emitted from an emitter 4 or an emitter group provided on one emitter electrode 3 divided, under a normal electric field condition, a positive electric potential of at least the same or greater as/than the electric potential of a gate 7 is applied to the other emitter 5 or an emitter group. When the emission is carried out by the other emitter 5, a preset positive electric potential is given to the emitter 4. By driving in this way, the electron e1 injected form one emitter 4 collides with the other emitter 5, which is cleaned thereby, and an electron e2 emitted from the other emitter 5 cleans the emitter 4. Stable electron emission is thus possible for a long period of time.
