Title: Ultrasonic microscope
Inventor: NAKAZATO TEKI
IPC: G01N29/00
Filed: 1985-09-03
Abstract: PURPOSE:To obtain a V(z) curve corresponding to a desired position by stopping an acoustic lens in a prescribed position in an ultrasonic microscope where the acoustic lens is oscillated in a prescribed direction in a plane orthogonal to the ultrasonic wave axis. CONSTITUTION:An acoustic lens 1 is provided on a holding member 2 and is oscillated in the direction of an arrow X by an exciter 3. The oscillation is controlled by a scanning controller 4. The light from a light emitting element 5 provided on the holding member 2 is received by a photodetector 6, and the output is supplied to the controller 4. The stop position signal set by an X coordinate designating circuit 7 is inputted to the controller 4, and the stop position of the acoustic lens 1 is fed back to the exciter 3 on a basis of the output of the photodetector 6 so that this position coincides with a desired position. Since the acoustic lens is positioned in the desired stop position in the oscillation direction, the V(z) curve corresponding accurately to the desired position is obtained from the ultrasonic image, and the stop position of the acoustic lens can coincide with the optical axis of an optical microscope.

Inventor: KATO TOSHIHIKO
IPC: C08G73/14
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain a liq. crystal orienting film stably ensuring a large pretilt angle and suitable for use in a device adopting a super-twisted nematic system by incorporating polyimide obtd. by allowing acid anhydrides including a specified amt. of specified dicarboxylic acid anhydride based on the amt. of tetracarboxylic acid dianhydride to react with a diamine. SOLUTION: This material for a liq. crystal orienting film contains polyimide obtd. by allowing acid anhydrides including 0.01-0.25mol, preferably 0.02-0.15mol dicarboxylic acid anhydride based on 1mol tetracarboxylic acid dianhydride to react with a diamine. The dicarboxylic acid anhydride is represented by the formula [where (n) is an integer of 5-29]. When the amt. of the dicarboxylic acid anhydride is <0.01mol, pretilt angle increasing effect is not satisfactory. In the case of >0.25mol, the resultant liq. crystal orienting film becomes brittle and peels at the time of rubbing.

Title: Solid state image pickup device
Inventor: MIZOGUCHI TOYOKAZU
IPC: H04N5/369
Filed: 1987-08-05
Abstract: PURPOSE:To obtain a solid state image pickup device of high sensitivity which can obtain an output signal having a high SN ratio and no after-image, by outputting the picture element optical signal with subtraction of the dark output signal stored in a frame memory when the picture element optical signal integrated for a fixed time is read. CONSTITUTION:A vertical scan circuit 113 of an image sensor 1 is actuated and a reset pulse and the read pulse set right after said reset pulse are applied to an SIT forming a picture element for each row line. The output signal read out at that point of time has an extremely short integration time and therefore regarded as a dark time output and the dark time output signals of each picture element equivalent to a single frame are written and stored into a frame memory 2. When a prescribed integration time Tint passed, the read pulse is applied again to the sensor 1 and the optical signal stored in each picture element is read out. At the same time, the dark time output signal is read out of the memory 2 in response to each picture element by the timing pulse given from a timing generator 5. Both the optical signal and the output signal are applied to a differential amplifier 3. Thus an output Vout free from the dark time output signal is obtained from a gate circuit 4 which is controlled by the generator 5.

Abstract: PURPOSE:To prevent the occurrence of peeling by bypassing individual passages partitioned with guide walls through grooves provided on the portions of a fan cover with which the upper end surface of the guide walls are brought into contact and feeding an air stream to a portion where peeling tends to occur from other guide passage. CONSTITUTION:Grooves 10 crossing with a guide walls 7 are provided on the portion of a fan cover 10 with which the upper end surface of the guide walls 7 are brought into contact. When peeling tends to occur as before at a low flow area, an air stream is fed to this portion B tending to become a low pressure from an adjacent passage A through the groove 10, and as a result no peeling occurs. Therefore, the fan can be used under a state that the used flow area is expanded to a low flow position beyond the design flow area of the fan. In addition, only the groove 10 is provided on the fan cover 8, a fan usable to a low flow area can be obtained only by replacing the fan cover 8 even for a fan currently in use.
