Title: Ink jet recording head
Inventor: YOSHIDA YOSHIHARU
IPC: B41J2/175
Filed: 1990-11-08
Abstract: PURPOSE:To discharge air bubbles which enter a passage easily, and save the quantity of ink which is required to discharge the air bubbles by filling a liquid which does not increase the wetting property on a nozzle surface, in the passage at the time of transport or storage. CONSTITUTION:When a head is shipped and stored as a single unit, an ink feeding port 2 is attached on an ink jet recording head 1, and the terminal end is sealed, and ink passages 9 are formed in the recording head 1, and are filled with transport liquid 10. The liquid to be filled retains hydrophilic effect for a hydrophilic-treated surface, and does not increase the wetting property of a nozzle surface, and the liquid has a group which hydrogen-bonds with an -OH group on the hydrophilic-treated surface, and the vapor pressure is not higher than 5mmHg (25 deg.C). Such type of liquid is polyhydric alcohols such as ethylene glycol, etc. By applying a liquid such as mentioned above at the time of shipping, wetting of an ink in the passages is retained, and entered air bubbles can be easily discharged, and an ink quantity which is used to discharge the air bubbles can be saved.

Title: Light beam tracking device
Inventor: AOYAMA JUNICHI
IPC: H04B10/11
Filed: 1989-11-21
Abstract: PURPOSE:To prevent the tracking control accuracy from being deteriorated transiently by predicting an attitude motion of the own satellite, feeding back a signal of this predicted satellite attitude error angle to a tracking driving part of a light beam, and improving the tracking accuracy to the other satellite. CONSTITUTION:By adding a satellite attitude sensor 1 and a satellite attitude predicting part 2, a transient response related to a compensation of a tracking error is improved. That is, the satellite attitude motion predicting part 2 predicts mainly a sudden satellite attitude motion by inputting a satellite attitude error angle containing a sudden attitude fluctuation outputted from the satellite attitude sensor 1 and a tracking deviation angle, and superposes it on a feedback control signal and inputs it to a tracking driving part 12 so as to offset it. In such a way, even if the attitude of a satellite is fluctuated transiently by the external/internal disturbance torque, high tracking control accuracy can be maintained.

Title: Digital demodulating device
Inventor: WADA YOSHIO
IPC: H04L27/22
Filed: 1994-11-14
Abstract: PURPOSE: To detect the timing point of demodulation in a short time by selecting two optimum couples of points for correction of a phase shift on the basis of a bit error estimation result and shifting one so that their correlation becomes equal. CONSTITUTION: The correlation detecting circuit 9 of a clock regenerating circuit 8 samples the levels of detection signals X and Y at plural extraction points which are previously sets in each symbol cycle. Then two adjacent extraction points are paired to detect the correlation between signals, and the signals X and Y are added by couples of extraction points and sent out to a correlation decision circuit 10. The circuit 10 compares correlation data stored in the circuit 9 to detect the couple of extraction points having the largest correlation and the following couple of extraction points. A bit error estimation part 11 estimates an error rate from the correlation value.  On the basis of the estimation result, a switching part 12 selects the optimum couple of extraction points for correction of the phase shift and a phase shifting means 14 shifts the phase of the signal in a demodulation process to equalize the correlation.

Abstract: PURPOSE:To facilitate the self-cleaning of a contactor, to reduce the number of solder chip eliminating processes, and to increase the quality of the products and the measuring efficiency by setting the size of a pusher for pushing an IC into the contactor properly and by controlling the stroke. CONSTITUTION:For measurement of an IC 4, the IC 4 is pushed into a contact block 2 by a pusher 5 for bringing IC leads into electric contact with a contactor 3. At that time, the width of the pusher 5 is made a little larger than the distance to the contactor 3. By this, the pusher 5 is pushed to a cleaning stroke several times. The movement of the pusher 5 needs a two-staged stroke mechanism, a stroke for IC contact and a stroke for cleaning. Then, the timing of the movement is controlled. By this method, an automatic self- cleaning of the contactor is available.

Title: Production unit for and production of sea salt by natural evaporation
Inventor: SHINJO YASUHIKO
IPC: C01D3/06
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To economically and efficiently obtain a natural salt by installing an outer wall and a water reservoir on aslant cement concrete floor, allowing seawater to thinly adhere to the floor, and then evaporating the seawater by the aid of solar heat or the atmosphere. SOLUTION: First, a cement concrete floor is slantly laid, a water reservoir is provided on the lower part of the inclined floor, and an outer wall on the other edge. Secondly, seawater is allowed to thinly adhere to the floor, and evaporated by the aid of solar heat or the atmosphere. Thirdly, seawater is allowed to flow from the top of the floor, and then flows through the surface of the floor and thinly adheres thereto, the rest of the seawater being accumulated in the reservoir. The seawater on the surface of the floor is immediately evaporated on its exposure to solar heat or the atmosphere; on drying, additional seawttter is allowed to flow again.  Thus, because of repeated seawater casting and evaporation to dryness, the seawater on the surface of the floor repeats crystallization and crystal melting, resulting in higher salt concentration of the seawater accumulated in the reservoir and therefore facilitating salt crystal deposition. For the floor, a multi-tiered design with slab structure increases land area, being effective in terms of mass production of the aimed sea salt. Furthermore, installation of a detachable cover and a roof enables the aimed sea salt to be produced without hindrance of any rainfall.

The electric signal from a liquid level sensor is transmitted to the control part 8 and the electric signal for stopping the suction action is transmitted from the control part 8 to the pump 63 when the liquid level falls, as a result of such suction action, down to the position where the liquid level sensor is mounted. The action to suck the specimen liquids from the nozzles 61 is thereby stopped. the control part 8 commands the action to a photometric device 7 in order to measure the optical density of the specimen liquids filled into the flow cells 62. The optical density of the specimen liquids is thereby measured. The measurement accuracy is thus improved.

IPC: G09B29/10
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To enhance the positional accuracy by correcting the absolute position data and relative position data obtained by an automatic navigation so as to allow the advancing direction and center-of-gravity position of the data to coincide. SOLUTION: An altitude and longitude detector 3 calculates the altitude and longitude from the reception signal of a GPS (general global position measuring system) receiver 1. An autonomic navigation sensor 3 detects the distance and direction by a distance sensor 3a and direction sensor 3b. A moving amount detector 4 calculates the relatively moved amount. A calculator 6 obtains the traveling locus. The calculator 6 selects the point of bending at a predetermined angle or more as a node point, and sets the line segments between the node points as an element. The calculator 6 so moves the element of the autonomic navigation that the advancing direction and center-of-gravity position of the element obtained by the autonomic navigation coincide with those of the element obtained by GPS to correct the position data.  The distance information of the autonomic navigation having small error and the directional information of the GPS are combined to be corrected to improve the positional accuracy of measuring the traveling locus.
