Title: Semiconductor optical modulator
Inventor: SODA HARUHISA
IPC: G02B6/12
Filed: 1989-08-09
Abstract: PURPOSE:To allow good-quality light transmission without causing wavelength chirping by admitting only the surely modulated laser beam to an optical fiber coupled to an output port even if a sepn. layer has about the thickness sufficient for executing directional coupling type optical modulation. CONSTITUTION:This modulator has an n type InGaAsP waveguide layer 2 which is a 1st waveguide, an n type InP sepn. layer 3, an n type InGaAsP waveguide layer 4 which is a 2nd waveguide, an electrode 6 of the directional coupling type optical modulator part MD which passes the current to change the refractive index in the one waveguide layer and an electrode 6' of an optical absorber part AD which passes a bias current in order to consume energy as a photocurrent when the laser beam is made incident on the light absorbing layer 4'. Only the surely modulated layer beam is, therefore, made incident to the optical fiber coupled to the output port Po even if the sepn. layer 3 between the waveguide layer which is the 1st waveguide 2 and the waveguide layer 4 which is the 2nd waveguide has about the thickness sufficient to execute the directional coupling type optical modulation. The good-quality light transmission without causing the wavelength chirping is executed in this way.

Filed: 1985-09-17
Abstract: PURPOSE:To make it possible to detect specific bacteria and to measure the concn. thereof, by immobilizing an antibody on the surface of an electrode and bonding specific bacteria by antigen-antibody reaction. CONSTITUTION:An electrode 2 having a Candida antibody 3 immobilized thereon is mounted to both surfaces of the thin plate of a quartz oscillator 1 to form a quartz vibrator biosensor which is, in turn, connected to an oscillation circuit 6 and a frequency counter 7 through lead wires 4 to constitute a measuring system. After the reference oscillation frequency of the sensor was measured, said sensor is immersed in a Candida bacteria solution for a predetermined time and oscillation frequency is subsequently again measured. Whereupon, the oscillation frequency increase dependent of the concn. of bacteria and, therefore, the concn. of bacteria can be calculated on the basis of the difference between the measured oscillation frequency and reference oscillation frequency.

IPC: H04N1/19
Filed: 1986-09-01
Abstract: PURPOSE:To always perform an accurate shading correction by automatically taking a reference value for shading correction at the intervals of an optimum time depending whether the data transmission speed is higher than a prescribed value or not. CONSTITUTION:A control part 10 drives a motor 5 through a motor driving part 9 by the image read start signal from a full color thermal transfer printer 12 to drive a carriage 7 under a reflecting plate 2. Then, a fluorescent lamp 1 is lit, and the reflected light is received by a light receiving part 3, and the part 3 sends its signal to a shading correcting part 8. In case of the full color thermal transfer printer 12, the information of a picture is transmitted at high speed, and therefore, an interface control part 11 detects that the transmission speed is higher than the certain speed, and the control part 10 does not take data for shading correction till the end of reading of one-picture components of information. In case of a personal computer, the transmission speed is lower, and the interface control part 11 detects it, and the control part 10 moves the carriage 7 under the reflecting plate 2 at every 10-second to take the data for shading correction.

Title: Heat regeneration type air cooling and drying apparatus with self-diagnostic function and its diagnosing method
Inventor: NISHIJIMA MAMORU
IPC: B01D53/26
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To perform maintenance at appropriate time and to reduce cost by providing the apparatus with a means by which temp. of an adsorbent is measured and condition of deterioration of the adsorbent is diagnosed from heat-up characteristics of the adsorbent when the adsorbent is regenerated based on the measured result and the result of diagnosis is informed. SOLUTION: A set value of heat-up rate is a set temp. value corresponding to every set value of heating time of a heater 13 and when an adsorbent is deteriorated, in the regeneration process, heat-up changing rate of the adsorbent at a point where a certain time has passed from the beginning of heating by the heater 13 is decreased. A judging part 19 utilizes this phenomenon as a reference for judging deterioration of the adsorbent and when the temp. value from temp. sensors 8a and 8b at the present time corresponding to the set value of heating time, namely, the present value of heat-up rate is smaller than the set value of the heat-up rate, it is judged that the adsorbing performance of the adsorbent is deteriorated and it is informed to a guidance output part 20.  When the guidance output part 20 receives the information from the judging part 19, it informs automatically it to an operator.

Title: Device for inputting fingerprint picture, and method therefor
Inventor: KURODE TSUYOSHI
IPC: G06T1/00
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To obtain clear fingerprint picture data with satisfactory contrast, to generate fingerprint picture data with a low noise level, and to evade a difficult point on an operation that a fingerprint examiner is exposed to a strong light or the like at the time of generating fingerprint picture data. SOLUTION: Scattering light picture data by a second light source 2 are subtracted from total reflection light and scattering light picture data by a first light source 1 so that fingerprint picture data obtained only from the total reflection light picture data can be formed. As a result, a clear picture with satisfactory contrast can be obtained by removing any unnecessary scattering light in total reflection method. Moreover, it is not necessary to improve the sensitivity of a second-dimensional image sensor, or to increase any light source light quantity like an optical path separation method. Thus, it is possible not only to obtain the fingerprint picture data with excellent S/N but also to evade a difficult point on an operation that a fingerprint examiner is exposed to a strong transmitted light or the like.
