Title: Eyeball image light-receiving device and eyeball image photoreception control method
Inventor: AOYAMA KEISUKE
IPC: G03B7/28
Filed: 1995-03-30
Abstract: PURPOSE: To suppress the influence of external light by detecting the reflection image of observer's eyeballs and its feature point, dividing the region of a reflection image into a plurality of parts based on the feature information, and obtaining the brightness information of the reflection image from information at each region. CONSTITUTION: The visual field of an image sensor 14 is divided into an AGC area 0 with the pupil position of the lowest brightness as a center, and AGC areas 1 and 2 for surrounding the AGC area 0, thus performing AGC control with an eyeball image as a reference. A CPU 100 turns on infrared LEDs 13a and 13b via an IRED drive circuit 107, and obtains the output of the sensor 14 with an accumulation time and amplification factor determined by the AGC calculation. Then, the eyeball image of a photographer is read and a cornea reflection (P) image and the feature of a pupil part are extracted to obtain the rotary angle of the eyeball light axis. Then, the coordinates of an observation point on a finder are obtained and the detection of line of sight is completed, thus obtaining a proper eyeball image which is not affected by external light and eyeball position.

Filed: 1990-04-11
Abstract: PURPOSE:To simplify calibrating work with the adjustment of an analog system with a possibility of generating errors as a whole at one point by providing a D/A converter to perform a calibration containing a digital system. CONSTITUTION:A comparison program is provided in microprocessor 1 to compare a correct temperature of a sensor 6 as given from a display operating section 2 with a temperature to be detected through an A/D converter 3. Then, a voltage level is adjusted as applied to an operational amplifier within a sensor amplifier 5 through a D/A converter 4 according to a comparison level. As a result, a temperature data read from the A/D converter 3 is adjusted by an output of the D/A converter 4. To be more specific, another thermometer is used to measure at what temperature the sensor 6 is currently and a reading is inputted into a processor 1 to control an output of D/A controller 4 therewith 1. This lets the output of the D/A converter 4 be adjusted so that a value the same as the reading inputted precedingly is read from the A/D converter 3, thereby achieving an automation of calibrating work.

Abstract: PURPOSE:To enable the execution of a diagnosis with high reliability at the time of making a medical diagnosis by providing a polarizing filter to an optical system in a manner as to image only the light contg. image information to an image sensor so that a sharp image is displayed. CONSTITUTION:This endoscope has an optical fiber bundle 38 for leading out irradiation light to a subject A, the image sensor of a CCD 42 which receives the light contg. the image information of the subject A, and the optical system 44 for forming the image to the image sensor.

Title: Refrigerator
Inventor: ITO YASUNOBU
IPC: F25B39/02
Filed: 1989-04-18
Abstract: PURPOSE:To prevent the generation of strange sound induced by vapor-liquid separated refrigerant, use effectively the entire area of a vaporizer and increase a cooling capacity by defining an inner diameter of an outlet pipe which introduces refrigerant in a vapor and liquid mixed state from an expansion valve to a vaporizer in a compression type refrigerating cycle. CONSTITUTION:In a compression type refrigerating cycle, an inner diameter of an outlet pipe 5, which introduces refrigerant in a vapor and liquid mixed state from an expansion valve 2 to a vaporizer 6, is designed 1.0 to 1.3 times an inner diameter of an inlet pipe 1 which introduces liquefied refrigerant to the expansion valve 2. This construction increases the velocity of atomized refrigerant flowing in the outlet pipe 5, eliminates vapor and liquid separation time, and rather promotes atomization, thereby preventing the generation of coarse liquefied particles. Moreover, agitation induced by high flow velocity promotes homogenization, the refrigerant flows into the vaporizer 6 and is distributed equally before vapor and liquid separation takes place, which prevents the generation of strange sound. Furthermore, since the refrigerant is equally distributed, the temperature distribution in the vaporizer 6 is equalized, thereby improving the cooling efficiency.

Title: Optical recording and reproducing device

IPC: G11B7/135
Filed: 1989-04-17
Abstract: PURPOSE:To prevent reproduced beams from decreasing, and to stabilize the reproduction of information recorded on an optical card and the respective controls of tracking and focusing by providing a wavelength plate selectively arranged on the optical path between a light emitting diode and a polarized beam splitter. CONSTITUTION:The phase of a first linearly polarized component from a light emitting diode LED is changed by 90 deg. with a wavelength plate HB to be a P polarized component, and the phase of a second linearly polarized component is changed by 90 deg. with the wavelength plate HB to be an S polarized component. For this reason, the first linearly polarized component accounting for major proportion is transmitted through a polarized beam splitter PBS, and the second component acounting for the minor proportion is reflected by the polarized beam splitter PBS. Consequently the reproduced beams for an optical card RM are increased. Thus the S/N of the information reproducing signal is increased based on the reflected beams for the optical card RM, information reproducing ability is improved, and the controls of tracking and focusing are stabilized.

Abstract: PURPOSE:To measure methane concentration quickly by contacting the microbiological electrode, in which methane utilizing bacteria are sealed, with gas to be measured, and sensing the reduction in dissolved oxygen in a solidified microbiological layer as an amount of reduction or reducing speed of the output current of the electrode. CONSTITUTION:In an outer tube 9, are contained platinum cathode 5, an alminum anode 6, and KCl elctrolyte 7. The microbiological electrode 10 is provided between a separating film 4 of an oxygen electrode and a dialysis film or gas transmitting film 3, and attached to a measuring cell 12. The methane utilizing bacteria 1 which oxidize methane and consume oxygen are sealed in the microbiological electrode 10. Air is sent into the cell 12. The gas to be measured is injected from an injecting port 16 for 1-5min at every 4--20min interval, dilluted by air, and contacted with the electrode 10. Methane is diffused in the bacteria 1, and oxidized by the bacteria 1. Oxygen is consumed and the concentration of the dissolved oxygen in the vicinity of the separating film 4 is reduced. Therefore the output current of the oxygen electrode is decreased and recorded in a recorder 13. The relationship between the methane concentration of the gas to be measured and the reduced value of the current has been obtained for standard methane gas, and the methane concentration is obtained from the height of the peak.
