Title: Electrophotographic apparatus
Inventor: NAKAHATA KIMIO
IPC: G03G15/16
Filed: 1979-09-29
Abstract: PURPOSE: To obtain a copy image free from uneven transfer and fog, by providing a transfer-preceding corona discharger between a developing device and a transfer charger in order to apply a specified bias voltage.  
     CONSTITUTION: Surface potential of photoreceptor 1 after development is +700V and +200V, respectively. Discharge electrode 4 is covered with discharger shield 5, and subjected to about 6kV AC voltage. Tungsten wires are stretched as a control grating at the position of the opening of discharger on the side of photoreceptor 1, and connected to bias voltage source 7. Bias voltage between the light and dark area voltage of photoreceptor 1 is selected in order to form an accelerating electric field and a restricting electric field of corona ions between the surface potential of photoreceptor 1 and the control grating. As a result, the dark area toner is charged more negatively to enhance transferability, and only the toner attached to nonimage areas is converted into a reverse polarity, thus permitting uneven transfer and fog to be prevented.

Title: Channel selecting device of television signal
Inventor: NISHIGAKI HIROSHI
IPC: H04N5/44
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To stabilize and complete channel selecting operation in a very short time by detecting the presence of a receive signal through a signal detector, when a broadcast in a channel plan frequency range is selected and received and carrying on the tuning operation of an automatic tuning circuit irrelevantly to the reception channel plan frequency range. SOLUTION: A channel selecting operation part selects a channel and outputs the center frequency of the channel immediately prior to the channel selection to perform automatic tuning(AFT) operation in bands at respective points, thereby detecting a signal. When a signal is present, the AFT operation is carried on beyond the channel plan frequency range. In the AFT operation, the number of steps at specific frequency intervals from each channel plan frequency range center frequency is counted and when the AFT operation continues beyond the channel plan frequency range, the channel plan frequency range at the end of the AFT operation is decided from the number of steps and regarded as new AFT last data; when next channel switching is performed, AFT operation is started from the last data of the new AFT.

Title: Optical beam scanner
Inventor: KAWACHI YOSHIKAZU
IPC: G02B26/10
Filed: 1990-05-16
Abstract: PURPOSE:To reduce the influence of wavelength variation in a reproducing laser beam even when the wavelength of the reproducing laser beam is varied by using a laser beam whose wavelength is longer than that of the reproducing laser beam at the time of forming holograms. CONSTITUTION:The holograms 4 are formed by a laser beam whose wavelength is longer than that of the reproducing laser beam 7. When it is defined that the phase transmission function of each hologram 4 is phiH, the phase of an incident wave is phiIN, the wavelength of the reproducing laser beam 7 is lambdac, and the wavelength of a producing laser beam is lambda, a light beam unit vector (s) determining the direction of a diffracted wave can be expressed by (lambdac/lambda) grandfH + grandfIN. Consequently, when the wavelength lambdac of the reproducing laser beam 7 is varied, if the ratio of variation in the wavelength lambdac of the laser beam 7 to the wavelength lambda of the producing laser beam is sufficiently small, the influence of the wavelength variation can be neglected. Thereby even when the diffraction efficiency is maximum and the wavelength of the reproducing laser beam is varied, the influence of the variation can be reduced.

Title: Defect inspecting device
Inventor: SUGIMURA KOICHI
IPC: G11B7/26
Filed: 1988-05-25
Abstract: PURPOSE:To easily and exactly execute a defect inspection by providing a space filter for eliminating a space frequency component of a rule pattern on an image forming optical system. CONSTITUTION:When a space filter 15 is provided on the second focal position 111 of an eyepiece 11 of a microscope 1, and an optical recording area of an optical memory card 4 is enlarged by the microscope 1, an enlarged image of the optical recording area from which a rule pattern has been erased is made incident on a camera 2. This image is converted to an image signal by the camera 2, and sent to an image processing part 3. In case when no defect exists in the optical recording area, a luminance signal is in a roughly prescribed level, but in case when a defect exists, an abnormal level variation is generated in the luminance signal. In the image processing part 3, a ratio in which a defect occupies in the optical recording area is calculated, and a defect rate is displayed digitally. In such a way, since a defect inspection is executed in a state that the rule pattern in the optical recording area has been erased, the inspection is executed exactly, and also, since the rule pattern is erased optically, an electrical image processing for erasing the rule pattern and an image processing by a software become unnecessary, and the constitution is simplified.

Title: Acid gas sensor
Inventor: DERIKU PURETSUCHIYAA
IPC: G01N21/78
Filed: 1988-05-27
Abstract: The present invention provides a sensor, preferably an electrochemical sensor, for detecting acidic gases, e.g. carbon dioxide. The electrochemical sensor has a sensing electrode (20, 22), a counter electrode (37) and a body of electrolyte containing a complex, e.g. copper(II) bis(propanediamine), which has one or more ligands that is displaceable by the presence of the acidic gas in the electrolyte to form a modified complex which can be electrochemically reacted at the sensing electrode at a potential at which the unmodified complex is unreactive. The acidic gas diffuses into the electrolyte through a porous membrane. The modified complex can also be detected colorimetrically because it absorbs light at a different wavelength to the unmodified complex.
