Title: Image sensor
Inventor: SHIBUYA MASATO
IPC: H04N5/335
Filed: 1989-10-25
Abstract: PURPOSE:To reduce the generation of aliases without complexing an optical system by providing each picture element with a peripheral part whose sensitivity is reduced from the center part in a prescribed direction. CONSTITUTION:It is defined that the total length of the center part 1a and peripheral part 1b of each picture element 1 in the scanning direction is b1, the length of the center part 1a in the scanning direction is c1, the sensitivity of the center part la is To, and the sensitivity of the peripheral part 1b is T1 lower than the To. Since the sensitivity distribution of respective picture elements constituting an image sensor is controlled, the value of a transmission function in a space frequency band exceeding the Nyquist frequency of the image sensor can be suppressed, the aliases of image information picked up by the image sensor can be reduced and a clear image can be obtained.

Abstract: PURPOSE:To improve image quality by forming the shape of a shutter element trapezoidally so that respective legs are parallel at contiguity parts. CONSTITUTION:An optical shutter array 10 is equipped with two arrays, i.e. array 11A of trapezoidal shutter elements 11 and a shutter array 12A of shutter elements 12 in the same shape at the center part. A common electrode 13 provided across the shutter arrays 11A and 12A or a control electrode 14 for the shutter elements 11 is equipped with trapezoidal lead parts 14l for connection with an external driving circuit and a control electrode 15 for the optical shutter 12 is also equipped with trapezoidal lead parts 15l for connection with the external driving circuit. Luminous flux which is cut off by the shutter elements 11 and 12 is projected trapezoidally on, for example, a photosensitive drum, but the photosensitive drum rotates, so this trapezoid draw a track to fill gaps between adjacent shutter elements.

Title: Particle analyzer
Inventor: OE SHINICHI
IPC: G01N15/14
Filed: 1987-10-31
Abstract: PURPOSE:To set a flow diameter matching with fluid particles automatically by providing a particle diameter information detecting means which detects particle diameter information on the sample particles and a means which sets the flow diameter corresponding to the detect particle diameter. CONSTITUTION:A control arithmetic circuit 17 controls a regulator 3 for sheath liquid and a regulator 4 for sample liquid at the start of measurement to set the flow diameter of a flow of sample fluid in a flow cell 12 to a certain specific value. The sample particles which flow at this time are irradiated with laser light from a laser 19. There is a correlation between the quantity of forward scattered light and the particle diameter, so a photodetector 22 detects the quantity of the forward scattered light at this time and compares it with a light quantity-particle size conversion table in the memory of a circuit 17 to calculate the particle size. Then the circuit 17 controls the regulators 3 and 4 so as to obtain a flow diameter nearly equal to the found particle size. Here, the pressure values of sheath liquid Sh and sample liquid Sa for obtaining the specific flow diameter are predetermined and stored in the memory of the circuit 7. Thus, the flow diameter matching with the particle size is set automatically.

Abstract: PURPOSE: To reduce the size of an entire mixer so as to reduce the space for installation by arranging multiple venturi paths in parallel with each other and providing a common gas inlet chamber for connecting gas fuel paths in each path. CONSTITUTION: When a throttle valve 9b is opened gradually from an idling condition, a pressure inside a negative pressure chamber A lowers because an engine side negative pressure acts also on a venturi part on the upstream side from the throttle valve 9b, a piston valve 12 opens the venturi part, and thus air flow rate increases so as to increase flow speed at the venturi part producing negative pressure and a clearance between a needle valve 14 and a main jet 11 also becomes larger so as to increase fuel flow rate. Also venturi paths 10a and 10a such operated are arranged in parallel with each other, a common gas inlet chamber 10b is arranged between both paths, and they are formed integrally. By this, a distance between the venturi paths 10a and 10a can be reduced, its entire size can be reduced, and also a space required for installation can be reduced.
