Title: Heat transfer pipe with internal grooves
Inventor: FUJIMOTO SHINJI
IPC: F28F1/40
Filed: 1987-01-12
Abstract: PURPOSE:To maintain a high performance of a heat transfer pipe after it is expanded by providing many trangle fins on the internal wall face of the pipe and a plurality of trapezoid fins which are higher and wider than the triangle fins and arranged with the same distance among them. CONSTITUTION:Many small grooves 5 are provided on the internal wall face of a heat transfer pipe 4 with the internal diameter, d0 of the pipe below 4 mm. In order to prevent the change in the shape of the groove 5 when the pipe is expanded, a plurality of trapezoid fins 6 are provided on the internal wall face of the heat transfer pipe 4 with the same distance among them. The groove 5 is constituted with triangle fins 7 with a sharp apex angle: the ratio of the fin width FW and its bottom width W is: W/W = 0.5-1.5; the height of the triangle fin 7 is: H1 = 0.12-0.15; the trapezoid fin 6 has a width A: A = 3FW-4FW; and the fin height H2 is higher than H1 by 0.02-0.05 mm. The trapezoid fins 6 change their shape a little by mechanical pipe expanding with the heigth H2 becoming H'2 which is lower than H2, but because the triangle fins 7 are lower than the trapezoid fins 6, the former do not change the shape after the pipe expanding. With this arrangement the lenght of the wetting edge of the liquid film at the grooves 5 in the pipe can be increased and after the assembly of a heat exchanger a high performance heat transfer pipe with a high coefficient of heat transfer in the pipe can be provided.

Abstract: PURPOSE:To improve the efficiency and to reduce the antenna axis by providing a main reflection mirror formed by bonding plural partial reflection mirrors being parts of plural paraboloids of rotation whose focii differ while a different turning center axis is used and providing a primary radiator radiating a radio wave to the main reflection mirror so as to overlap the part of the radiated region of the partial reflection mirror. CONSTITUTION:The main reflection mirror 1 is formed by bonding a partial reflection mirror A' being a part of the paraboloid of rotation A and a partial reflection mirror B' being a part of the paraboloid of rotation B while the turning center axes (a), (b) are directed in different directions. The primary radiators 21, 22 apply radio wave radiation so as to overlap parts of the radiated region of the corresponding partial reflection mirror. In this case, each radiation region is regarded as the independent rotating paraboloid reflection mirror. Thus, the shape of the curved face of the overlapped part of the radiation region A'' is made close to the curved shape of the rotation paraboloid A and the curved face of the overlapped part of the radiation region B'' is made close to the curved shape of the rotation paraboloid B. Moreover, the antenna axial length is reduced by applying indirect radiation between the main reflection mirror 1 and the focal points Fa, Fb of the primary radiators 21, 22 via a flat reflection plate.

Filed: 1978-01-23
Abstract: PURPOSE:To sufficiently perform the suppression of pulsive noise even in the amplitude modulation receiver, by detecting the pulsive noise having different band width than that of signal to be received mixing with the signal to be received. CONSTITUTION:During the noise mixing period, demodulation signal is gated out with the gate signal and the signal value is held to the value immediately before the value during this period. In this case, the IF signal amplified with the IF amplifier 17 is detected 18, then it is fed to monostable multivibrator 21 through the BPF 19, and the output closes the gate circuit 20 and operates the hold circuit 22. Further, the pulsive noise is detected with the noise detector 18 mixed in this signal with the delivery system having the different band width then that of the signal to be received. Thus, the pulsive noise can sufficiently be suppressed even in the amplitude modulation receivers.

Title: Parity control system for dual port memory
Inventor: SUDO KAZUYOSHI
IPC: G06F12/16
Filed: 1988-01-14
Abstract: PURPOSE:To eliminate the occurrence of parity errors in a read state by writing the dummy data into a sub-memory SAM forming a dual port memory and then transferring the data to a RAM from the SAM even in case the number of data transferred and written into the SAM is smaller than the capacity of the SAM. CONSTITUTION:A DMA control circuit 4 counts the data which are transferred and written into a SAM1-1 forming a dual port memory 1. If the count value of the data is smaller than the capacity of the SAM1-1, the remaining dummy data (with parity) are transferred and written to the SAM1-1. Then data are transferred to a RAM1-2 from the SAM1-1. In such a constitution where the dummy data written even in case the number of data transferred to the SAM1-1 is smaller than the capacity of the SAM1-1, no parity error occurs when data are read out.

Title: Protector for compressor driver
Inventor: DEGAWA TAKU
IPC: F16D27/14
Filed: 1979-01-24
Abstract: PURPOSE: To protect the driving source from disturbance due to the burning of compressor, by providing means for detecting the slip between rotary members at the sides of driving source and compressor which constitute the clutch and releasing the operation of clutch.  
     CONSTITUTION: When turning a switch to supply power to the coil 5 of electromagnetic clutch 3, magnetic field is produced around the coil 5 thereby the disc 14 is attracted to the rotor 7. Consequently the rotation of engine 8 is transmitted to the shaft 9 of compressor 1. When the compressor 1 is burnt due to some cause under this condition to stop the rotation of said shaft 9, it causes slip between the rotor 7 and the disc 14. This slip is obtained as the difference of rotation by a processing circuit 19 in pickups 17, 18 provided respectively on the rotor 7 and the disc 14, and when it exceeds over predetermined level power is blocked from the coil 5 to release the clutch.
