Title: Optical modulator
Inventor: SANO HIROHISA
IPC: H01S5/026
Filed: 1990-04-12
Abstract: PURPOSE:To make chirping small by providing a light absorption area, a modulating means which modulates incident light by varying its absorption coefficient, and an optical waveguide area which compensates variation in the refractive index of the area. CONSTITUTION:The optical modulator is equipped with the light absorption area 3 where the incident light is absorbed, the modulating means which modulates the incident light by varying the absorption coefficient of the light absorption area 3, and the optical waveguide area 4 for compensating the variation in the refractive index of the light absorption area 3. Namely, the upper and lower layers of an undoped area and a substrate 7 are doped to the mutually different polarities (n,p) to form a p-i-n type diode. Then a reverse bias voltage is applied to the diode to produce a high electric field in the undoped area and the absorption coefficient of the light absorbing layer is varied by band structure variation (Franz-Keldysh effect or quantum confinment Stark effect) by electric field application to modulate light. In this case, the refractive index varies simultaneously with the absorption coefficient. Consequently, the chirping phenomenon of phase modulation which is caused simultaneously with intensity modulation is prevented.

Title: Hydrophilic member
Inventor: FUJIMOTO HIDEFUMI
IPC: C04B41/89
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a hydrophilic member capable of restoring the hydrophilicity after washing in an ultrashort time and having high sustained effects of the restored hydrophilicity. SOLUTION: This hydrophilic member is obtained by forming a tin oxide (SnO2) film 2 on the surface of a glass plate 1 as a substrate and forming a silicon oxide (SiO2) film 3 as an overcoating layer on the surface of the tin oxide (SnO2) film 2. Soda glass consisting essentially of SiO2 is used as the glass plate 1 and the tin oxide (SnO2) film 2 is formed by, e.g. a chemical vapor deposition (CVD) method. The thickness thereof is 10-800 nm and the surface average roughness (Ra) of the surface is 0.5-25 mm. The silicon oxide (SiO2) film 3 is formed by sputtering and the thickness thereof is 0.1-100 nm. Since the silicon oxide (SiO2) film 3 is formed on the tin oxide (SnO2) film 2, the unevenness of the tin oxide (SnO2) film 2 is intactly transferred and the surface average roughness (Ra) of the surface of the silicon oxide (SiO2) film 3 is 0.5-25 nm.

Title: Digital controller
Inventor: KINO ETSUJI
IPC: G05B7/02
Filed: 1983-05-31
Abstract: PURPOSE:To shorten both the transfer time and the control arithmetic cycle with a digital controller by transferring the past value only with the past value data on a desired arithmetic circuit. CONSTITUTION:A CPU which is under control transfers only the analog and logical intermediate values which require the prescribed past value to a CPU under waiting together with the process control with a process controller containing multiple CPUs. The waiting CPU starts an intermediate value CLA reception task 22 and stores the intermediate value data to a buffer area 25. The waiting CPU performs the arithmetic processing with the control task and then the reception data fetching processing. Then the output value of an integration circuit, etc. is refreshed to the data received from the CPU under control. Thus the next control arithmetic processing is carried out with the refreshed control data value. If the control cycle is sufficiently smaller than the time constant, the approximately equal arithmeric data value is obtained between the control and waiting modes. Thus the bumpless switching is possible for a digital controller.
