Inventor: SEO KATSUHIRO
IPC: G11B11/105
Filed: 1990-07-31
Abstract: PURPOSE:To simplify the constitution of an optical pickup device by attaching a uniaxial crystal plate to a supporter which supports a photodetecting element having plural photodetecting faces in such a way where the crystal plate is set opposite with tilt to each photodetecting face of the photodetecting element. CONSTITUTION:A photodetector 7 is provided with a photodetecting element 8 having plural photodetecting faces, a supporter for the element 8, and a uniaxial crystal plate 9 which is set opposite with tilt to each photodetecting face of the element 8. Therefore the incident luminous flux condensed on the element 8 is deflected by the plate 9 attached to the supporter for the element 8 in terms of the traveling direction of the luminous flux in response to the deflecting direction. At the same time, the luminous flux produces the astigmatism according to its focusing state. Thus it is possible to obtain a read signal which reads the information signal written on a magneto-optical disk, a focus error signal which shows the focus error value of the luminous flux incident on the signal recording surface of the disk, etc. In such a constitution, an optical pickup device is easily assembled and manufactured in a simple constitution.

Title: Atomizer for slurry fuel
Inventor: BABA AKIRA
IPC: F23D1/00
Filed: 1984-09-28
Abstract: PURPOSE:To decrease unburnt content in ash without increasing the concentration of NOx in exhaust gas, and to increase combustion efficiency of coal-water mixture (CWM), by controlling the flow rate of spray medium contacting with coal-water slurry below 9% at the gas-fluid ratio. CONSTITUTION:Coal-water mixture, CWM6 is boiled as its pressure is reduced immediately after it is injected into a furnace from an atomizer nozzle 7. There is a little time lag before CWM6 injected from the nozzle 7 is atomized and then is diffused. Therefore atomization ban be taken place continuously without delay by spraying a very little quantity, below 9% at the gas-fluid ratio of steam from a steam feed pipe 15 in the center of a burner. The CWM6 is sufficiently heated, boiled and atomized before it reaches the atomizer nozzle 7 by supplying such a small quantity of injection medium to the CWM6, because a heating jacket is provided around a feed pipe 17. There exists not such a tendency that NOx is suddenly decreased nearly above 0.5% at the gas-fluid ratio being accompanied with the increase of gas-fluid ratio as is seen in conventional atomizers, and unburnt content is increased.

IPC: G09F9/00
Filed: 1986-08-29
Abstract: PURPOSE:To accurately evaluate the change with the lapse of time without destroying a panel by measuring optical characteristics of a liquid crystal cell under various driving conditions and calculating characteristic parameters of a driving element and the liquid crystal cell. CONSTITUTION:A control circuit 8 controls the timing, amplitude, and waveform of the gate voltage VG and data voltage VD of the liquid crystal panel 12 through a driving timing generator 9, a control power source 10, and a driver circuit 11. In this constitution, only when the voltage VG has a constant DC value or when a gate bus line is scanned, a pulse is applied to generate a B(brightness)-V(voltage) characteristic chart as to respective combinations of rectangular wave or pulse voltages VD having various amplitudes. Respective threshold voltages are found from them and the characteristic parameters are calculated by specific arithmetic operation. Therefore, the change with the lapse of time change is accurately evaluated even after the liquid crystal panel is completed.

Title: Facsimile transmission system
Inventor: OSAKO KENJI
IPC: H04N1/00
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain the synchronism between transmission and reception of a facsimile so as to obtain instantaneity by arranging a facsimile distributing equipment provided with a means for inserting FILL to facsimile image data between a data line and a public telephone line. SOLUTION: A facsimile receiving equipment 3 and the facsimile distributing device 5 are arranged between the data line other than the telephone line of Internet, etc., and the existing telephone lines 2a and 2b. The facsimile receiving device 3 converts received image data into a format which can be transmitted by Internet by each line. The facsimile distributing equipment 5 converts image data received from the internet 4 into the format which can be transmitted by the telephone line by each line. In this case, a variable length signal string of zeros called FILL for canceling the difference in the signal rate between the transmission facsimile equipment and the reception facsimile equipment 6 is inserted before a signal indicating the end of one line.  Thus, transmission is attained after obtaining synchronization so that whether data is transmitted to an opposit party or not is instantaneously recognized.

Title: Seat
Inventor: MIZUTANI SAORI
IPC: B60N2/42
Filed: 1994-08-30
Abstract: PURPOSE: To diverge a shock in landing and to provide no damage to the human body by providing a seat body having center of gravity at its rear rather than a revolving shaft, and means for fixing the seat body for preventing rotation and for releasing the fixing on acting force exceeding tolerance on the seat body. CONSTITUTION: A strain gage 7 is not necessarily installed on all seats. The seat bodies having no strain gage 7 receive a signal sent from a control pack 15. Igniting a blasting cap 13 releases a stopper bolt 5. Center of gravity then moves to the front of an airframe when force is applied from the rear of the airframe, resulting in rotating the seat body to give a backward state since the center of gravity of the seat body is backwardly located rather than a revolving shaft 4. Thus the seat body faces the force-applied direction, resulting in that a passenger constantly receives force with the entire back through a backrest 6b. In addition, a shock received from the airframe is diverged by rotating the seat body.
