Title: Production of spirally finned tube
Inventor: FUJIMURA HIROSHI
IPC: B21C37/26
Filed: 1988-10-21
Abstract: PURPOSE:To prevent the rupture of fins and to produce the spirally finned tube more smoothly with higher efficiency by applying the deformation of about half the total deformation amt. which the fins receive from bending rollers to the fins as a fore stage to wind the fins on the tube. CONSTITUTION:The fin bending rollers 26, 27, 28 are rotated by a driving motor 29 and the fins 2 are continuously curved and are fed into spiral grooves formed on the surface of a guide cylinder 23. The positions of the bending rollers 26, 27, 28 are set to maintain the radius of bending of the fins 2 in such a manner that the tensile deformation amt. of the outer peripheral part attains about half the tensile deformation amt. in the outer peripheral part when the fins are wound on the tube 1. The radius of the grooves of the guide cylinder 23 is selected according to the bending radius of the fins 2. The part near the outer periphery of the fins 2 is heated by a gas burner 30 just before the fins are fed into the guide cylinder 23. The rupture of the fins at the time of winding the fins is prevented in this way and the spirally finned tube is produced smoothly with the high efficiency.

Filed: 1984-12-17
Abstract: PURPOSE:To cool a lead wire sufficiently by liquefying a refrigerant gas stored in a buffer tank by the excess refrigerating capacity of a refrigerator on the non-use of the lead wire while returning the gas into a heat-insulating vessel. CONSTITUTION:Helium gas which has been stored in a buffer tank 17 is compressed by a compressor 7, liquefied by the excess capacity of a refrigerator 6 and returned into an inner vessel 1 at a point of time when currents are adjusted completely. When lead wires 19a, 19b are employed, helium gas used for cooling the lead wires 19a, 19b is stored previously into the buffer tank 17.

Title: Power transmission device
Inventor: SHINOHARA MITSURU
IPC: G03B13/36
Filed: 1991-10-15
Abstract: PURPOSE:To provide a power transmission device in which the changeover from autofocusing to manual-focusing can be quickly carried out without requiring changeover operation. CONSTITUTION:A power transmission device is characterized in that the power transmission device itself can select the driving source by axially moving a helical gear by utilizing an axial reaction that is caused when helical gears are engaged with each other. When a helical gear 4 is turned by a motor 1 for autofocusing use, an axial reaction is caused in a helical gear 5 that is engaged with the helical gear 4, thereby the gear 5 moves on a shaft 8 so as to be integrated with either of a gear 6 or a gear 7, so that the power of the motor 1 is transmitted to a driven body via a gear 10 through either of the gears 6, 7. On the other hand, when the gear 10 is turned by a manual-focusing device that has been connected to a gear 11, the helical gear 5 is disconnected from the gear 6 or the gear 7, thus the gear 5 becomes independent of power transmission.

CONSTITUTION: 2M bit fields address a memory 112 which stores approximate advanced distorting values (FI0 , FQ0 ). Also, 2(N-M) bit fields are inputted to an interpolating circuit 111. In this case, the two (N-M) bit fields express values Δx and Δy for each channel, and the two M bit fields express values (x) and (y) for each channel. Then, the interpolating circuit 111 calculates corrected data (FI, FQ) with the help of the values Δx and Δy based on the approximate data FI0 , FQ0 and the address fields. Thus, the distribution of each point of the original constellation chart to its cloud can be reduced.

Abstract: PURPOSE:To attain sound collection excellent in understandability with high sound quality even under high sound noise by providing a high pass filter extracting a high frequency component of an output of a main microphone, a low pass filter extracting a low frequency component of an output of a sub microphone and an output adder of both filters. CONSTITUTION:An output level of a sub microphone 12 is adjusted by a sensitivity adjustment device 14 in order to correct the level difference from a main microphone 11 due to a distance difference. A high frequency component with a deteriorated frequency characteristic is eliminated from the sub microphone output after level adjustment by a low pass filter 15 and only the low frequency component with excellent frequency characteristic and S/N is extracted. On the other hand, a low frequency component with a deteriorated frequency characteristic is eliminated from the main microphone output by a high pass filter 13 and only the high frequency component with excellent frequency characteristic and S/N is extracted. Thus, the high frequency component from the high pass filter 13 and the low pass component from the low pass filter 15 are added by an adder 16. Thus, an output with excellent frequency characteristic and S/N over all the frequency bands is outputted externally from the adder 16.
