Abstract: PURPOSE:To reduce the number of pieces of light receiving elements, to upgrade resistance to electrical noise, and to make the noise less noticeable by providing a wide angle lens having a shape of an elliptic body of rotation on a light receiving surface on the top surface of a shielding case. CONSTITUTION:An optical wireless receiver as a satellite receiver consists of a piece of light receiving element 1 contained in the shielding case 2 only the light receiving surface 1a of which is exposed from the top surface of the case 2, and the wide angle lens 11 having an elliptic body of rotation disposed on the light receving surface 1a on the top surface of the case 2. The mounting piece extended from the lower side surface of the lens 11 is mounted on a print circuit board 12 on which the shelding case 2, etc., are mounted. The lens 11 refracts beams (a)-(c) whose incident angles phi0 are small as an ordinary lens does, but reflects beams (d) and (e) whose incident angles phi0 are large also in order to condense beams in a prescribed position. Since the one piece of light receiving element 1 can receives beams from 360 degrees of direction, the number of pieces can be decreased.

Abstract: PURPOSE:To get rid of variations in an air quantity to be fed to each cylinder, by installing a central discharge port and a terminal discharge port both in the downstream of an element, and also installed a baffle plate in the rear inside a case in the central discharge port. CONSTITUTION:In flows of air having come up along a rear wall 29 of a convex chamber part 23 after passing through a filter element, such one that went up along both ends of the rear wall 29 of the convex chamber part 23 does not collide with a baffle plate 39 but b umps against a side wall of case 17 of terminal discharge pipes 33 and 35. Since another air, going up along the central part of the rear wall 29 of the convex chamber part 23, collides with the baffle plate 39, some air is as well accumulated in and around the opening inside the case 17 of the central discharge pipes 31 and 31 like in case of these terminal discharge pipes 33 and 35. In consequence, these central discharge pipes 31 and 31 and terminal discharge pipes 33 and 35 feed each of cylinders with air without entailing any variations.

Title: Solid-state image pickup element
Inventor: NISHIMURA RYUSHI
IPC: H01L27/14
Filed: 1985-09-27
Abstract: PURPOSE:To suppress a white balance deviation at high illuminance by changing a saturation level in response to spectral sensitivity characteristics of a photoelectric conversion element at each picture element signal read from the photoelectric converting element. CONSTITUTION:A BG gate is separated at signal changes W, Cy, Ye, G and a different voltage is fed respectively to 4 gates of BGw, BGcy, BGG, BGre to change the saturated electric charge quantity at each color. Since the saturated signal quantity of the G signal electric charge is decreased equivalently by applying a voltage to the BGG gate higher than that of the BGw gate, an excess signal electric charge G' overrides the BGG gate at a time t3 and an undesired signal is discharged to a drain BD of a sweep-out gate 8G. Thus, each saturated signal quantity of W, Cy, Ye, G signal electric charge is made different and the application voltage to each gate is set independently so as to be saturated at the same incident luminous quantity depending on the spectral sensitivity of each color filter to arrange the saturated luminous quantity equivalent. Thus, the white balance deviation at high illuminance and high light green are suppressed.

Abstract: PROBLEM TO BE SOLVED: To satisfy good initial activity, a high hydrogen storage capacity and a long service life characteristic, by specifying particle diameter and its average particle diameter and also specifying the included quantity of powdery particles in this particle diameter range and the specific surface area of particles, in hydrogen storage alloy powder. SOLUTION: Between a negative pole produced by using hydrogen storage alloy powder which includes more than 90weight% hydrogen storage alloy powder particles whose particle diameter is 5 to 100μm and average particle diameter is 20 to 70μm and the specific surface area of the particles is more than 0.5m<2> /g, and a positive pole containing nickel oxide, a separator is interposed and stored in a tightly sealed container and alkaline electrolyte is filled therein, the then a nickel hydrogen secondary battery is formed. This hydrogen storage alloy powder is filled in a hydrogen storage unit and thus used for a hydrogen driven automobile. This hydrogen storage alloy powder is obtained by pulverizing the hydrogen storage alloy in water solution containing about less than 0.5 phosphoric acid or phosphate compound.  Since local heating owing to pulverization is diffused in the water solution, an oxide film caused by heating is hardly formed on the surface of pulverized powder particles.

Abstract: PROBLEM TO BE SOLVED: To form an emitter guard layer with excellent reproducibility, by epitaxially growing a collector layer, a base layer and a part of an emitter layer on a substrate, and selectively growing the residual emitter layer in a region turning to a transistor intrinsic part. SOLUTION: After collector layers 2, 3, a base layer 4 and a part 5 of an emitter layer are epitaxially formed on a substrate 1, the residual emitter layer 8 is selectively grown in a region turning to a transistor intrinsic part 7. In order that the part 5 of the emitter layer positioned in the peripheral part of an emitter mesa may function as an emitter guard ring layer for preventing recombination, the thickness is set to be depleted by a depletion layer stretching from a junction to the base layer 4. As a result, the guard ring layer having a film thickness of high precision can be formed with excellent reproducibility, so that a recombination current in the peripheral part of an emitter mesa can be reduced, and characteristics and reliability concerning HBT development can be improved.

Abstract: PURPOSE:To increase the processing speed by transferring data to a shared resource after release of a common bus in the case of the occurrence of write access to the shared resource at the time when the common bus in a data transfer device is occupied. CONSTITUTION:A processor 4 has a priority level higher than that of a processor 5. When processors 4 and 5 try to simultaneously access a shared memory 18, the processor 4 first accesses the memory 18 for read, and the processor 5 interrupts the processing till the end of the access of the processor 4 and accesses the memory 18 for read after the end.
