Title: Heat transfer pipe
Inventor: NISHIWAKI FUMITOSHI
IPC: F28F1/40
Filed: 1986-05-22
Abstract: PURPOSE:To increase the heat transfer performance of the heat transfer pipe by providing triangular and thin grooves in which a plurality of vertical angles have less than predetermined value, on the inner wall of the pipe having a maximum inner diameter of less than a predetermined value. CONSTITUTION:Thin grooves 7 and 8 having a truncated cross sectional shape are formed on the inner wall of a heat transfer pipe 6 having a maximum inner diameter of 4mm or less. The vertical angle theta of a triangular fin formed between the groove 7 and the adjacent groove 8 is set as 0 deg.<theta<=20 deg.. A coolant flows within a heat transfer pipe 6 in the direction indicated by arrow 10, and is varied in its phase while heat-exchanging with a fluid outside the pipe. In the case of transferring an evaporation heat, the coolant flowing into the heat transfer pipe 6 in a two-phase flows collect heat from the outside of the pipe while flowing within the pipe, and changes the flowing style toward the pipe axial direction while evaporating. The value of the fin vertical angle theta is set as 0 deg.<theta<=20 deg., whereby the length of an open veranda can be increased, that is, the pipe heat transfer area can be increased.

IPC: G01T1/161
Filed: 1985-05-31
Abstract: PURPOSE:To gather correction data in a short time and to reduce contamination by using an easy-to-handle spot light source by measuring variance in collimator efficiency only for the 1st time and calibrating a detection system periodically or at any time. CONSTITUTION:Data of a columnar light source 3 are collected through a collimator 2 for the 1st time to calculate a coefficient of correction and the spot light source 4 is used instead of the light source 3 at this time to gather data without the intervention of the collimator 2. Then, data are gathered by using the light source 4 for the 2nd and succeeding times without being passed through the collimator 2. The data obtained for the 1st time without being passed through the collimator 2 and the data obtained for the 2nd and succeeding times without being passed through the collimator are compared with each other to make factor corrections. Thus, correction data are gathered in a short time and the easy-to-handle light source 4 is used to reduce radioisotope contamination.

Title: White balance adjusting circuit
Inventor: NODA MASARU
IPC: H04N9/73
Filed: 1980-08-29
Abstract: PURPOSE:To adjust white balance by adjusting the indication of a meter to the zero- point even if color temperature is extremely high, by inducing an effective offset to the meter which indicates the level difference of an R-B signal when gain control range of channels R and B are large. CONSTITUTION:Control voltages for R and B gain control circuits 3a and 3b are obtained from a variable resistor 6 and they are passed through a resistance 7 to give a meter an offset voltage. Consequently, if color temperature is high, the voltage dividing ratio of the variable resistor is lowered to increase the gain of a channel R while decreasing that of a channel B. At the point where the meter indicates a zero point, the gain of the channel B is not lowered more actually when it has no offset, so a signal R is set somewhat lower and a signal B is set somewhat higher.

Abstract: PURPOSE:To prevent the slip of a sheet-shaped article by installing a variable speed transporting means between a cutter and a high speed transport means and gradually increasing the transport speed of the sheet-shaped article and allowing said speed to reach the transport speed of a high speed transport means. CONSTITUTION:In the state where the first transport roller 13 and a feed roller 12 are in stop, a long film 10 is cut to a prescribed length by the upper and lower cutters 14 and 15. When a cut completion detecting means 24 detects said cut, a controller 25 drives a servomotor 21 through a driving circuit 26 by a signal S2, and the film 10 having the prescribed length is transported to the second transport roller 17 of a high speed transport device by the first transport roller 13. In this case, the revolution speed of the servomotor 21 is increased to the speed equal to the peripheral speed of the second transport roller 17, and when this speed is generated, the transport state is maintained. Thus, the trouble due to the slip of a sheet-shaped article can be prevented.

Title: Compressor blade
Inventor: ABE HIROSHI
IPC: F04D29/30
Filed: 1977-10-04
Abstract: PURPOSE: To give blade for compressor hardening treatment by laser irradiation to improve wear-resistance and fatigue strength.  
     CONSTITUTION: The whole surface of blade which is used for valve part of compressor to feed into refrigerant gas is given impact-hardening treatment by irradiating laser. By doing so, wear-resistance and fatigue strength can be improved compared to that with no laser treatment. In this case, laser hardening treatment is favorable as it would not deteriorate the surface condition nor it creates evil effects such as transormation or distortion like other hardening methods do, and laser is capable of applying treatment only on the desired spot as its output or irradiating part can be appropriately selected. These are effective not only for valve steel used for ordinary blade but also for blade of various special steels
