Title: Optical handwritten character pattern input device
Inventor: ABE KIYOMI
IPC: G06F3/03
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To eliminate the need to install a detecting mechanism on a display panel surface by detecting the position of an input pen on an input surface when the input value photodetected by the input pen reaches a certain level from the angle between two rotary mechanisms and an elapsed time from a device which detects the reference position of light. SOLUTION: The surfaces of mirrors on flanks of two rotary mirrors 1a and 2a are irradiated with light beams from semiconductor lasers 1b and 2b to make a rotary scan on the entire input surface 4 in parallel. The light after this rotary scan is converted by the input pen 3 into an electric signal, which is amplified by an amplifier 12 and inputted to a control substrate 10. This electric signal is detected as the elapsed time from the time when detection is performed by photodetecting elements 1c and 2c for reference position setting to the detection when detection is performed by the input pen 3. Consequently, the need to install a detecting mechanism on the input surface 4 is eliminated and functional restrictions are reducible.

Title: Optical fiber having ultraviolet setting cover
Inventor: JIYOOJI PASUTAANATSUKU
IPC: C08G59/68
Filed: 1990-11-05
Abstract: PURPOSE: To obtain an optical fiber having a low modulus protective coating film which is rapidly hardened by exposing to UV rays to prevent defects due to minute bending and can maintain low modulus preferable at low temp. (-60 deg.C) by coating a fiber with a UV-initiating cation-hardening type liquid coating compsn. CONSTITUTION: The coating film is composed of a UV-initiating cation-hardening type liquid coating compsn. which is hardened by exposing to UV rays, and the compsn. contains a cation-hardening type polyepoxide, polysiloxane having lots of hydroxyalkyl groups, photoinitiator and/or photosensitizer for activation with UV rays and cation hardening. The modulus of the base coating for such optical fiber is far low at -60 deg.C compared to a compsn. commercially used. Thereby, such a problem is prevented that the coating film generates strain at low temp. and the strain induces minute bending to decrease the transmitting ability of the optical fiber for rays.

Title: Method and device for driving piezoelectric transformer
Inventor: SASAKI HIROSHI
IPC: H02M3/24
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for driving piezoelectric transformer, which can widen the variable range of the output voltage of a high-voltage power unit using a piezoelectric transformer. SOLUTION: A method for driving piezoelectric transformer incorporates a first control method for controlling the boosting rate of a piezoelectric transformer 13 and a second control method for controlling the driving waveform of the transformer 13. A hysteresis characteristic is given to the threshold for switching the control methods to each other, so as to avoid the drive of the transformer 13 at its natural frequency by eliminating the occurrence of an irregular drive frequency. When the power supply voltage is fixed, the drive frequency is raised and the boosting rate is reduced from that at the time of the maximum output voltage, by changing the resistance value of a resistor 16 for detected, until the drive frequency reaches the natural frequency at which a trouble occurs. When the frequency reaches the natural frequency, the amplitude of the driving waveform is reduced by reducing the power supply to a drive circuit 12 so as to lower the driving frequency, without changing the output voltage. The minimum output voltage is obtained by raising the drive frequency to the natural frequency, by again changing the resistance value of the resistor 16 while the amplitude is small.

Title: Artificial satellite attitude control device
Inventor: OBATA TOSHIHIRO
IPC: B64G1/36
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To enable detection and control of a yaw angle by means of a sensor regardless of orbital position or season by providing a means of calculating the yaw angle based on a relative position with respect to other satellites and a direction from which a signal arrives obtained by a signal processor and a control means that generates an attitude control torque according to the yaw angle. SOLUTION: The angle formed by a direction vector of a signal 51 and a negative direction vector 56 of a roll axis is assumed to be θy. A yaw angle 2 is obtained as the angle formed by the negative direction vector 56 of a roll axis and an orbital plane direction vector 16. The angle formed by the orbital plane direction vector 16 and the direction vector of the signal 51 is a given angle obtained from a relative position 55, being a relative position 55/2. When the yaw angle 2 is obtained by correcting θy with this given angle, an attitude control electronic circuit 10 controls the yaw angle 2 through a simple technique that requires no selection of a sensor or control method according to an orbital position, or no correction according to the season.  This allows the yaw angle to be detected and controlled through simple processing at all times regardless of orbital position.
