Title: Optical space transmitter
Inventor: ASANO TAKESHI
IPC: H04B10/112
Filed: 1994-05-17
Abstract: PURPOSE:To obtain the best light receiving power density at all times at the reception side regardless of the transmission distance by varying the emitting beam diameter for the transmission object according to the distance between the measured object to be transmitted. CONSTITUTION:A distance measurement circuit 90 of an optical space transmitter 10 at the transmission side calculates the device-to-device distance (d) based on the delay time (t) required to return a pulse for transmission distance measurement being reflected on the corner cubprism of the transmitter 10 and the light speed (c) by d=c.t/2. Thus, the circuit 90 which measures the distance from the device 10 generates the driving control information of a voice coil motor 92 according to the measured distance. Then the information is sent to a voice coil motor driving circuit 91. The circuit 91 generates the driving signal of the voice coil motor 92 based on the driving control information. When the measurement distance is short, a lens 38 is approached in the direction separated from a laser diode 36 of the lens 38 in the direction enlarging the light emitting beam diameter or in the direction reducing the beam diameter.

Title: Method for purifying potassium tantalum fluoride
Inventor: SHINDO YUICHIRO
IPC: C01G35/00
Filed: 1990-04-20
Abstract: PURPOSE:To readily obtain high-purity potassium tantalum fluoride with hardly any high-melting metals and radioactive elements by charging crude potassium tantalum fluoride into hydrofluoric acid, increasing the temperature, then adding a solution containing K<+> thereto, subsequently cooling the resultant mixture solution and separating a solid from a liquid. CONSTITUTION:Crude potassium tantalum fluoride is charged into hydrofluoric acid or a mixed acid containing the hydrofluoric acid and the resultant solution is then heated to 50-95 deg.C. A solution containing potassium ions is subsequently added to the solution and the mixture is then cooled to separate a solid from a liquid. The concentration of the hydrofluoric acid in the aforementioned solution is preferably >=25wt.%. This is because the potassium tantalum fluoride is hardly dissolved at a temperature thereof below ambient temperature if the concentration of the hydrofluoric acid in the above-mentioned solution is <25wt.%. Even if the temperature is then increased, the amount of the dissolved potassium tantalum fluoride is small. The amount of the potassium chloride used recrystallizing the potassium tantalum fluoride is 0.5-1.2 equiv. based on the theoretical value.

Title: Optical disk device
Inventor: ISHIKAWA YASUHIKO
IPC: G11B7/085
Filed: 1991-04-09
Abstract: PURPOSE:To record and reproduce the information in a short time by emitting a laser beam and starting the prescribed focus control before the rotating speed of an optical disk rises up to a stationary speed. CONSTITUTION:Before the rotating speed rises up to a stationary speed after a rotating motor 2 is started, the laser beam is emitted from a laser diode 14a and the prescribed focus control, that is, the focus pull-in and servo control are started. The light quantity of the emitting laser beam is increased in accordance with the rise of the rotating speed of the rotating motor 2. Thus, since the focus control by a focus servo control circuit 16 is earlier completed and the subsequent tracking control can be earlier performed, the information can be recorded and reproduced in a short time after the rotating motor 2 is started. Since the light quantity of the laser beam is made small while the rotating speed is slow, the damage of the information recording surface of an optical disk 1 can be prevented.

Abstract: PURPOSE: To automatically supply an ink to a ribbon in the continuous feed mode and thereby realize the printing of characters of uniform density by providing a container element with a means to first seal the ink in a first chamber and selectively flow the ink to a second chamber. CONSTITUTION: An ink container 42 has a seal 60 arranged between a first and a second chamber which are formed in case parts 56, 58, and an ink is allowed to enter only the first chamber formed in the case part 56. When a cartridge device is used, a pin 64 arranged in the case part 56 is actuated to penetrate a less resistant part 66 of the seal 60 and the ink flows into a lower chamber formed in the case part 58 to saturate a wick 44 with the ink. When a ribbon 12 moves forward part a cylinder 34 and a roller 16, a coil spring 48 generates a reactive force to transfer the ribbon 12 to a second position 54 shown by a broken line from a rear wall 36 and causes the ribbon 12 to engage with the wick 44. Consequently, in accordance with the advance of the ribbon 12, it becomes engaged with the wick 44 simultaneously in a position away from the rear wall 36.  On the contrary, when a printer stops its operation, the ribbon 12 is automatically pulled away from the wick 44.
