Patent JP-H02219035-A (JP)
Title: Exposure control method
Inventor: KANAI MASAHARU
IPC: G03B7/099
Filed: 1989-02-20
Abstract: PURPOSE:To accurately control exposure even in backlight, etc., by setting a correct exposure level using plural photodetectors subjected to photometry of a field to be photographed by dividing the light and providing a sub-diaphragm for simultaneously integrating the light of the field to be photographed with the exposure start and closing a shutter blade when the integrating value is at the exposure level previously set. CONSTITUTION:When a shutter button is half depressed, an exposure control circuit 45 is activated, the photodetectors 21 to 25 divide the light of the field to be photographed into five and execute photometry to a photometry region, and a photomet ric brightness signal is logarithmically compressed by logarithmically compressing circuits 51 to 55 and inputted to a scene discrimination computing part 57. At the scene discrimination computing part 57, the scene discrimination of backlight, direct light, spot light, etc., is performed, and the exposure level setting part 58 sets the exposure level Vth based on the scene discriminating signal. When the shutter button is released, the shutter blade starts to open, and the light of the field to be photographed is simultaneously integrated through the sub-diaphragm 39b, and when the integrating value reaches the exposure level Vth, the shutter blade closes and the exposure is completed. Thus, the correct exposure is realized even in the backlight.

Title: Electrolyte for driving electrolyte capacitor
Inventor: MORITA KOICHI
IPC: H01G9/02
Filed: 1989-02-20
Abstract: PURPOSE:To prevent corrosion of a capacitor effectively even if it is washed with a chloric solvent by adding 8-hydroxyquinoline. CONSTITUTION:Electrolyte consists of one or more of organic acids, inorganic acids and salts thereof dissolved as a solute in a solvent principally composed of ethylene glycol. The electrolyte according to the invention further contains 8-hydroxyquinoline dissolved therein. Any solvent entering inside a capacitor is first decomposed slightly by reaction with the electrolyte and then AlCl3 is produced by reaction between aluminum ions derived from an aluminum case or tab and chloride ions derived from decomposition of the solvent. The AlCl3 is hydrolyzed to liberate chloride ion, which corrodes aluminum to produce AlCl3. Since 8-hydroxyquinoline produces a chelate compound with aluminum, production of AlCl3 is prevented and liberation of chloride ions is suppressed. Thus, the 8-hydroxyquinoline gives an anti-corrosion effect to the electrolyte.

Title: Vane type rotary compressor
Inventor: SUDO YUKIO
IPC: F04C28/26
Filed: 1985-02-27
Abstract: PURPOSE:To prevent the chattering of a vane by forming a throttle in a passage for the communication between a low-pressure chamber and the back-pressure chamber of the vane positioned in a working chamber on the suction closing side. CONSTITUTION:When a suction port 14 formed onto one working chamber is closed by a check valve 35 in order to reduce the capacity of a compressor, the high-pressure coolant on the discharge side acts onto the suction port 14, and high-pressure state is formed at the part. When a plunger 38 is shifted against a spring 39 by the high pressure, the lubricating oil in a back-pressure passage 11 of the vane communicating to a communication groove 41B flows into a low-pressure chamber through the throttle part 50B of an inclined hole 50. Since the degree of reduction of the oil pressure in the vane back-pressure passage 11 is properly adjusted by the throttle part 50B, the collision of a vane 10 with a cam surface can be prevented in any working chamber.

IPC: G02B21/00
Filed: 1991-03-06
Abstract: PURPOSE:To prevent an image from deviating owing to driving condition variation of an exciting means as to the scanning type microscope where an optical system which irradiates a sample with illumination light is held at a tip part of a tuning fork and the exciting means vibrates the tuning fork to scan the same with the illumination light. CONSTITUTION:A dummy probe 15 is fitted to the tip part of the tuning fork where the optical system is not held and a grid pattern 60 is scanned with light emitted from it. The reflected light from the grid pattern 60 is passed through an optical fiber 14' and detected by a photodetector, and a sampling clock is generated according to the output signal of the photodetector which varies periodically and sent to an A/D converter. The A/D converter which samples and digitizes the continuous output of the photodetector detecting the light from the sample 23 samples the output at intervals of one main scanning line according to the sampling clock.

Title: Automatic molten metal feeder of die-casting machine
Inventor: OKUYAMA TERUO
IPC: B22D17/30
Filed: 1979-04-04
Abstract: PURPOSE:To reduce the working time from scooping up of molten metal up to its pouring by putting on a chain between the chain wheel fitted to the support shaft of a small arm provided with a ladle and the large-diameter chain wheel secured to a main shaft and suitably restraining the revolution of the large-diameter chain wheel. CONSTITUTION:When a chain 19 moves around a large-diameter chain wheel 7 while changing its intermeshing position along with the turning of a large arm 3 from the furnace A to the pouring port B, a small-diameter chain wheel 13 moves while chaning its direction in the clockwise direction owing to the difference in the number of teeth from the chain wheel 7 and the small arm 12 secured to the chain wheel 13 thrns clockwise, causing a ladle 15 to be conveyed up to the pouring port B while drawing a mild curve close to straight line. Hence, the working time from the scooping up of molten metal up to its pouring is reduced. At the scooping-off and scooping-up of the molten metal in the furnace A, the restraining of the large- diameter chain wheel 7 is released and this enables the ladle 15 to be moved upward and downward by holding the small arm 12 in the approximately perpendicular state by way of the chain wheel 13 in the same direction as the chain wheel 7, thereby eliminating the spill of the molten metal.

Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide an MRI device capable of correcting a magnetostatic field by the nonuniformity of the magnetostatic field in a short time with high accuracy. SOLUTION: An MRI device has a means for mensurating the nonuniformity of a magnetostatic field as a means for correcting the magnetostatic field nonuniformity, a shim coil producing an additional magnetic field to the magnetostatic field, and a means for calculating, according to the mensurated magnetostatic field nonuniformity, a shim coil current that may produce a magnetic field canceling out the nonuniformity. The means for mensurating the magnetostatic field nonuniformity applies a high frequency prepulse 101 causing nuclear magnetic resonance at a frequency deviated from the average resonant frequency of the subject of an examination object, then applies a pulse train, and collects echo signals 111 to obtain image data including local signal intensities matching the map of the magnetostatic field nonuniformity.  Such mansurations are made twice while varying the central frequency of the high frequency prepulse, and the ratio of the local signal intensities between two images is calculated to prepare a magnetostatic field nonuniformity map.

Abstract: PURPOSE:To evade an erroneous operation without executing strict time control at the time of switching transmission and reception by providing communication control parts respectively connected with main and slave (plural) control parts and executing connection between the control parts and the communication control parts by means of a logic inverse circuit. CONSTITUTION:This system is controlled by the polling control of the main control part 1M. The control part 1M sets the communication control part 2 to be a transmission mode (terminals RE and DE to H) through an output port (Cont). In this case, the specified communication control part 2 of the slave control part is set to be a reception mode (the terminals RE and DE to L). Here, the control part 1M transmits data to specified 1S, gives transmission right to the specified slave control part 1S and set its communication control part 2 to be the reception mode (the terminals RE and DE to L). The slave control part 1S which obtains transmission right sets the communication control part 2 to be the transmission mode (the terminal RE and DE to H) so as to start transmission. A misapprehension caused by an output terminal R to be L at the time of the switching is executed matching by the logic inverse circuits 6 and 7 so as to evade the misapprehension.
