Patent JP-S616592-A (JP)
Title: Finned heat exchanger
Inventor: AOYAMA SHIGEO
IPC: F28F1/32
Filed: 1984-06-19
Abstract: PURPOSE:To remarkably improve the air side heat transfer rate by reducing the dead water region in the after current of heat transfer pipes and promoting the disturbance of air flow due to the blowing-off of air flow and generation of vortices by a structure wherein upright shaved parts having a large number of holes thereon are provided perpendicular to a flat plate fin between a row of the heat transfer pipes on upstream side of air flow and a row of the heat transfer pipes on downstream side of air flow on the flat plate fin. CONSTITUTION:A group of horseshoe vortices developed on the upstream side of air flow of heat transfer pipes 7 and 8 can be moved round the pipes in the after current regions of the pipes by providing cut-and-rised parts 12 and 13 in the after current regions of the heat transfer pipes 7 and 8 and consequently the so-called dead water region can remarkably be reduced. In addition, because a large number of holes 10 and 11 are respectively provided on the cut-and-rised parts 12 and 13, the flows flowing over the upper parts of the cut-and-rised parts 12 and 13 and the flows blown-off through the holes 10 and 11 promote the disturbance of air flow, resulting in mixing the flows favorably. Furthermore, the resultant mixed flows adhere to a flat plate fin 5 again at the downstream sides of the cut-and-rised parts 12 and 13, resulting in remarkably improving the air side heat transfer rate.

Title: Transistor synthesis amplifier
Inventor: UCHIYAMA OSAMU
IPC: H03F3/181
Filed: 1981-08-12
Abstract: PURPOSE:To improve the return loss between a plurality of input signals and the directivity between the signals, by feeding back and output of a transistor (TR) of the final stage to an emitter of the TR circuit at the first stage of common- base connection via a feedback circuit. CONSTITUTION:Feedback is made from the emitter of a TR circuit 22 of the 3rd stage to the emitter of a TR circuit 20 of the 1st stage through a feedback resistor 23. Signals from input terminals 9-12 are synthesized through input impedance matching resistors 24-27 and given to the emitter of the TR circuit 20 of the 1st stage through a DC block capacitor 4. In a circuit of common-base with feedback entirely, since the impedance viewing the emitter is very low, the impedance viewing the entire amplifier from each input terminal is the same as the input impedance matching resistors 24-27 and the input return loss can be decided with the value of the resistors 24-27. The directivity between the input signals can be improved because of the low imput impedance.

Filed: 1990-05-16
Abstract: PURPOSE:To uniform differences among respective gradations to be used and to attain simple and rapid display control by rewriting the contents of registers corresponding to respective colors used by a color changing register group based on a uniformed gradation difference. CONSTITUTION:A color data changing part 100 inputs color data read out of a video RAM 4 and reads out and outputs stored color data from a register 62 corresponding to the read color data and a gradation converter 64 executes prescribed color/single color gradation conversion to convert a color image into a single color gradation image.

A register writing means 42 rewrites the contents of the register corresponding to the using color in the color changing register group 62. Consequently, gradation differences among respective using colors can be uniformed independently of the number of gradations and rapid display control can be executed.

Title: Seal structure for rotary drive motor
Inventor: KUNII YOSHIMASA
IPC: F16J15/44
Filed: 1989-05-22
Abstract: PURPOSE:To improve the seal performance against grease leakage by forming an air current generating section for generating the forced air current toward the bearing support section side in conjunction with the rotation of an inner rotor on a partition wall portion between fine walls. CONSTITUTION:When an inner rotor 30 is rotated in the preset direction, the grease G of an upper bearing 21 tends to scatter together with the air current A toward the radial direction. A labyrinth seal 71 is formed at a gap portion 70, thus the air current A is gradually attenuated when it is discharged to the labyrinth 71 side. On the other hand, a forced air current S toward the downward side from a spiral groove 60 portion is generated in conjunction with the rotation of a rotor hub 32, and the grease G moved on the attenuating air current A is sealed. The grease G is not sent at all to the outside from the gap 70 portion between an outer housing 10 and the rotary hub 32, and the grease G from the upper bearing 21 is completely prevented from scattering to the outside and sticking to a polygonal mirror.
