Title: Photometric optical system for external light injection system white balance device of video camera
Inventor: IIDA KOJI
IPC: G03B7/099
Filed: 1986-09-22
Abstract: PURPOSE:To prevent a drop of the light quantity of a light beam which has been made incident on an image forming lens system, and to equalize an illuminance distribution on the surface of a photodetector, by constituting the titled system of the image forming lens system being different from a photographic lens, and a condenser lens for projecting an exit pupil of its image forming lens system, onto the surface of the photodetector positioned in the rear. CONSTITUTION:A light beam is made incident from the left, and an image of an object to be photographed is formed on a condenser lens 5 by an image forming lens 4. Subsequently, the condenser lens 5 projects an exit pupil of the image forming lens 4 onto the photodetecting surface of a photodetecting part 6 for detecting a color temperature, which is placed in the rear. In this way, the photodetecting part 6 receives the light beam, and based on its output, an automatic white balance is executed. That is to say, since a white diffusion plate and a lenticular lens are not used, the light beam reaches the surface of the photodetector without dropping the light quantity. Accordingly, with respect to an object to be photographed of a low illuminance, as well, the white balance can be executed. Also, since the light beam is diffused onto the surface of the photodetector by using the condenser lens, nonuniformity of a diffusion caused by a directivity of the diffusion plate does not occur.

Title: Microwave ion source
Inventor: TOKIKUCHI KATSUMI
IPC: H01J37/08
Filed: 1985-10-11
Abstract: PURPOSE:To obtain a microwave ion source in which induction of B<+> current can be stably performed for long hours, by providing the microwave ion source with an oxygen-releasing material which releases oxygen or oxygen compound gas into vacuum. CONSTITUTION:A plate 13 made of copper is mounted on a ridge electrode part near a plasma chamber 5, with an electrode end fixed on a flange. As a discharge box is warmed by heating in accordance with plasma ignition in this case, a proper amount of oxygen gas is effectively released from the copper plate 13. Hence, because duration hours of operation become about twice and therefore frequency of exchanging an ion source becomes about half, a working ratio of the ion source is improved twice or more, with remarkable improvement found in ion-implanting yield. And, because an oxygen gas bomb becomes unnecessary together with regulation of gas amount being needless,safe operation can be obtained.

Title: Optical reception circuit
Inventor: KANENO KENJI
IPC: H04B10/50
Filed: 1990-08-29
Abstract: PURPOSE:To suppress an output waveform distortion of a preamplifier circuit and to improve the maximum light receiving level by using a current bypass circuit so as to bypass an optical current inputted to the preamplifier circuit at a region where an average light receiving level is exceeded. CONSTITUTION:An optical signal is converted into an optical current by an avalanche photodiode 1 and the optical current is subjected to current-voltage conversion by a preamplifier circuit 2. When an optical signal of an excess light receiving level is inputted to the avalanche photodiode 1, an input current to the preamplifier circuit 2 is increased up to the order of several mA, the preamplifier circuit 2 is completely saturated and its output waveform is abnormal. Then part of the optical current inputted to the preamplifier circuit 2 is bypassed by a current bypass circuit 10 to prevent saturation of the preamplifier circuit 2. Thus, the output waveform distortion of the preamplifier circuit is suppressed and the maximum light receiving level is improved.

IPC: B65H63/00
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To improve the detection sensitivity of a surface blot by comparing the luminance value of each picture element of image information with the prescribed luminance value, using it as blot candidate data when it is smaller than the prescribed luminance value, calculating the area value of the blot candidate data with an area calculating means, and judges the position as a blot when the calculated area value is larger than the prescribed area value. SOLUTION: A binarization circuit 7 serving as a binarization processing means compares the image information read by an image reading means with the reference luminance value, separates the image information into a high-luminance portion and a low-luminance portion, and sets a high-luminance point to '0' and a low-luminance point to '1' for binarization. An area measurement circuit 8 serving as an area measuring means calculates the area of a group of picture elements set to '1' by the binarization circuit 7, a comparison circuit 9 serving as a judging means judges the group of picture elements as a 'blot' and outputs an alarm signal when the area of the blot candidate is larger than the reference area set in advance, and a package blot is automatically inspected. The detection sensitivity of a surface blot and the detection accuracy of the blot can be improved.

Title: Data processor
Inventor: KARASAWA ISAO
IPC: G06F5/00
Filed: 1988-09-09
Abstract: PURPOSE:To reduce the capacity of a status buffer memory by writing only the status of the erroneous data to the status buffer memory and then reading the status out of the buffer memory only when the erroneous data is read out of the buffer memory. CONSTITUTION:In case the input data has no error, the data is stored in an error flag buffer memory 11 and the writing of the data is inhibited to a status buffer memory 6. When the input data has an error, the data is stored in the memory 11 and at the same time only the error status is stored in the memory 6. When the data and the status are read, an error bit is also read out of the memory 11. Then the status is read out of the memory 6 only when the error bit is valid. Therefore it is not required to store the status of a normal state into the memory 6. Thus the capacity of the menory 6 can be reduced.

Abstract: PURPOSE:To expand a dynamic range by arranging waveguide light beams and amplifying them with different amplification factors, applying them to individual transducers, and using on light beam with enough power for the detection of a photodetector. CONSTITUTION:Divergent light 12 guided from a semiconductor laser 3 to an optical waveguide 2 is divided by a collimator lens 19 into waveguide light beams 23 and 24 which have nearly equal power. An electric signal from a signal generation source 9, on the other hand, is applied to the transducers 29 and 30 by an electric feeding system 10 to excite surface acoustic waves 31 and 32 respectively. Here, when electric signals applied to the transducers 29 and 30 are made different in power, diffracted light beams 26 and 28 also differ in power and are condensed on convergent spots C and D through Fourier transforming lenses 17 and 18 and detected by photodetectors 20 and 21. Then a discriminator 11 analyzes a frequency and estimates power by using the photodetection signal of the detector 21 when the signal of the detector 20 enters a detectable range. Consequently, the dynamic range can be expanded.

Title: Radiation detector
Inventor: OMURA TOMOHIDE
IPC: G01T1/20
Filed: 1991-09-05
Abstract: PURPOSE:To accurately detect the incident timing of radiation such as gamma rays by taking the correlation between the output signals of two avalanche photodiodes (APD). CONSTITUTION:When one gamma ray photon is incident to a scintillator 1, photons are formed in the number corresponding to the energy thereof. The outputs corresponding to said photons are obtained from an APD1 and an APD2 and the possibility wherein the generation timings of noises contained in said outputs become same in the APD1 and the APD2 is low. Therefore, the correlation signal accurately corresponding to the incidend timing of gamma rays is obtained. The output signal waveform of a fast filter amplifier and the irregularity of timings are processed on the basis of a certain threshold value. The timings t1, t2, at that time respectively hold irregularities DELTAt1, DELTAt2, within definite ranges. However, by taking the correlation between both timings by a signal processing circuit, the irregularity DELTAT of timing T is reduced. That is, the incident timing of gamma rays is accurately detected.
