Title: Actuator
Inventor: SUZUMORI KOICHI
IPC: A61B1/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide an actuator suitable for driving a columnar or cylindrical device such as an endoscope and capable of being easily attached and detached to/from a driving object. SOLUTION: An actuator main body 1 composed of an elastic body is provided with plural pressure chambers 1a-1d extending a long the longitudinal direction B of the main body 1 and arrayed in the width direction A of the main body 1 in the inside. On both sides in the width direction of the main body 1, engaging parts 2a and 2b provided with a mutually engageable shape are provided. Plural projections 3 are erected on the surface of the main body 1 and the main body 1 is helically wound around the columnar driving object, the endoscope for instance. By a pressure controller 20, an air pressure is impressed in an order to the pressure chambers 1a-1d so as to generate advancing waves advancing in the width direction A of the main body 1 on the surface of the main body 1.  The projections 3 amplify the advancing waves generated on the main body 1 and the projections 3 receive reaction from an object in contact with the projections 3 and drive the columnar driving object in the axial direction. The main body 1 is easily attached and detached to/from the driving object.

Title: Vibration damping device
Inventor: ICHINOTO SEIICHI
IPC: F16F15/02
Filed: 1983-04-11
Abstract: PURPOSE:To cancel out the vibration of a columnar member or a beam for effectively damping vibration, by arranging, in the columnar member or the beam in a position other than the fixed ends thereof, a spherical member having a natural vibration frequency substantially equal to that of the columnar member or the beam so that the spherical member may be rolled in a spherical concave part. CONSTITUTION:When an axial air-gap motor 11 is driven, a rotary drum 5 rotates so that a molecular pump 24 is operated for introducing, into the rotary drum 5 through a feed pipe 19, gas to be dissociated. The above-mentioned gas is subjected to large centrifugal force in the rotary drum 5, and therefore, is dissociated into heavy gas component and light gas component. By the way, a scoop pipe 8 vibrates during the above-mentioned operation, but since a spherical member 32 is disposed in the lower end of the scoop pipe 18 so that the member 32 may be rolled in a spherical concave part and since the spherical member 18 vibrates, having 180 deg. phase difference with respect to the vibration in the direction orthogonal to the axis of the pipe 18, the friction force between the spherical member 32 and the concave part and as well the inertia force of the spherical member 32 which are caused by the phase difference, cancel the vibration of the pipe 8.

These used catalysts are quickly washed with water or a dilute aq. son. of sulfuric acid, nitric acid, hydrochloric acid, etc., whereby they are removed of stuck materials. When the pollution by dust or poisonous materials is heavy, these are further washed with a heated aq. oxalic acid soln. Thereafter, an SiO 2  slurry of 0.3W2.0 poise viscosity contg. V compds. or further compds. of W or Mo is coated thereon, after which the catalysts are dried and are calcined.

Filed: 1979-05-23
Abstract: PURPOSE: To make the starting of electromagnetic rotation fast and make the braking at the stopping good with simple constitution by adding elastic force of springs, etc. in controlling rotating force.  
     CONSTITUTION: Permanent magnets 1 are connected to a connecting ring 3 by pins 1b... penetrating in oblong holes and are made turnable about axis 1a.... Since the turning force based on the attraction force by the electromagnet 2 while coils L... are not energized is larger than the turning force in the opposite direction by the elastic force of springs 5, the ring 3 is held contacted with stoppers Pc, etc. and is held stopped. When the coils L... are energized in this state, the ring 3 is started at a high speed and is turned by the repulsive force by the magnet 2 plus the elastic force of the springs 5, in response to the magnets 1.... When the ring 3 turns at the specified angle, the springs 5 are charged and becomes the braking force at the stopping of the ring 3. This becomes the device suited for controlling of shutter blades, aperture blades, etc.

Then, the inserting jig 10 is made to shift to a socket S5 according to an X-direction socket pitch (f) and the operation is again performed to sockets S6-S8 according to the Y-direction socket pitch (e). When this operation is repeated the number of times fewer one than the number of the sockets being arranged in the X-direction (a), the insertion into all the sockets ends. According to this constitution, the total processing can be completed with only 6 information and the operability of the X-Y table is improved.

Title: Repeated call device
IPC: H04M1/27
Filed: 1992-03-19
Abstract: PURPOSE:To produce a repeated call in a simple manner when an incoming side is busy or has no response to the calling. CONSTITUTION:When a handset is hooked up and dialed, the dial number is described (S1). When the terminating side is busy or absent and has no response, (S2), the hand set is set beside a telephone set (S4) while hooking-up the handset as it is. A hook switch is effectively turned off and then turned on after a time T, and the stored dial number is called (S5). When no response is received in such conditions, the step S5 is reset (S6). When a response is recognized, a stored announcement ('You have a call from ..., wait a minute please.', etc.) is sent to the incoming side. At the same time, a fact that a response is recognized is announced to the caller (S7). Thus the caller hooks up the handset and talks to complete the calling (S8). Such a repeated call device is built into the telephone set or set between a circuit and the telephone set.

Filed: 1979-05-25
Abstract: PURPOSE: To improve an effect of the steps by a method wherein a plurality of inlet blades and outlet blades are arranged at the inlet end and the outlet end of the labyrinth seal side surfaces, respectively.  
     CONSTITUTION: The inlet blades 46 and the outlet blades 47 are arranged at both annular side surfaces of labyrinth seal 36, respectively. In this way, the inlet blades 46 prevent a flow of the leaked flow 37 to increase the pressure and decrease a pressure difference between the main flow at the stepped parts to decrease a flow of the leaked flow 37 or to return the balance hole passing flow to the stepped main flow. The outlet blades 47 prevent the fluid flow 32 leaking from shaft to increase the pressure, decrease a difference between the labyrinth inlet pressures and then a shaft leakage flow 32 at the stepped part is decreased. As a result, the leaked flow 37 is decreased and the main return flow at the stepped part is decreased or in turn the reversing flow may be available. In this way, the effect at the stepped part may be improved.

Title: Burning state detecting device for internal combustion engine
IPC: F02P17/12
Filed: 1992-03-19
Abstract: PURPOSE:To reduce the possibility of an erroneous diagnosis of a burning state of an engine during a normal operation by diagnosing the abnormality in combustion from both a rotating state and a burning state parameter of the engine and prohibiting the diagnosis of the burning state, based on the result of detection of the load fluctuation. CONSTITUTION:A parameter calculating means calculates a burning state parameter based on the result of detection of a rotating state detecting means 100. Comparing this parameter value with a threshold value 1, a burning state judging means 200 judges whether or not abnormal combustion takes place. On the other hand, a load detecting means detects that a clutch was connected suddenly, a tire is slipping, a brake is put on, or that the car is running on a bad road. A diagnosis prohibiting means 300 compares these detection values with a threshold value 2. If it is judged that a sudden change in the load has ossurred, the action of the burning state judging means 200 is suspended. With this constitution, the possibility of erroneously diagnosing a change in the engine load, which occurs at the time of braking or bad-road-running, as abnormal combustion such as a misfire can be reduced.
