Title: Heat exchanger tube and its manufacture
Inventor: KIDO OSAO
IPC: F28F1/40
Filed: 1988-06-10
Abstract: PURPOSE:To make the dimensions of width and height of a passage small, to lower the flow resistance and to improve the thermal conductivity by providing a flat tube and a fin having three sides of roughly a triangle in its tube, and joining the fin and an inner wall of a long side of the flat tube by a brazing filler metal. CONSTITUTION:A fin 10 which is formed by combining isosceles triangles consisting of a plane 10a being parallel to a long side 9b and a slant face 10b extended to its opposite side at an acute angle and provided with an interval so that the adjacent planes 10a do not come into contact with each other is inserted into a tube of a hollow-like flat tube 9 consisting of a short side 9a and a long side 9b. In this state, by executing a pressure rolling in the direction of the short side 9a from both faces of the long side 9b of the flat tube 9 by a roll machine, the flat tube 9 is further flattened. Subsequently, by heating the flat tube 9 and the fin 10 in a heating furnace and melting a brazing filler metal, the inner wall of the long side 9b of the flat tube 9 and the fin 10 are joined and the thickness in the short side direction is thinned to the finish dimension, and they are allowed to adhere closely by brazing. Accordingly, the thickness in the short side direction of the head exchanger tube 9 can be made small easily, and a flow resistance of a fluid of the outside of the tube can be lowered.

Title: Voice analyzer
Inventor: TAGUCHI SATORU
IPC: G10L25/90
Filed: 1978-11-24
Abstract: A speech analyzer with improved pitch period extraction and improved accuracy of voiced/unvoiced decision comprises circuits for calculating autocorrelation coefficients forwardly and backwardly with respect to time. Reference members for the forward and the backward calculation are those successively prescribed ones of windowed samples of a signal representative of speech sound which are placed in each window period farther from a trailing and a leading end thereof, respectively. Members to be joined to the respective reference members for forward and backward calculation of each autocorrelation coefficient are displaced therefrom by a joining interval farther from the leading and the trailing ends, respectively. The joining interval is varied between a shortest and a longest pitch period of the speech sound stepwise by a spacing between two successive windowed samples. One of the joining intervals for which the greatest of the autocorrelation coefficients is calculated during each window period gives a better pitch period for that period than ever obtained. The circuits may comprise a circuit for calculating a rate of increase of an average power of the speech sound in each window period and an autocorrelator for carrying out the forward and the backward calculation when the rate is less and greater than a preselected value, respectively. Alternatively, the circuits may comprise two autocorrelators, one for the forward calculation and the other for the backward calculation.

Title: Motor control cilrcuit
Inventor: IGUCHI SUSUMU
IPC: H02P3/12
Filed: 1980-10-20
Abstract: PURPOSE:To prevent electric power from being consumed when necessary operation ends even with a power switch closed by applying an electric generation brake to a motor once the operation of the motor ends and by stopping power feed to a motor control circuit on the braking operation. CONSTITUTION:In the automatic focusing AF mechanism of a camera device, a power switch SW1, mode SWs 2 and 3 are turned on successively, a transistor TRQ1 turns on to feed electricity to a block AF, and a voltage is developed at the terminal PW of an IC2 to turn on a TRQ8, thereby maintaining power feed to the AF. In this state, when AF operation is performed and the number of pulses from contacts A2 and B2 for distance measurement is stored in the IC2, a voltage is developed at a terminal M2 to turn on TRs Q2-Q4, and consequently a motor M is turned normally to move a lens, thereay applying pulses from the contacts A1 and B1 to the IC2. When the number of the pulses becomes coincident with the stored number of pulses, the voltages at the terminals PW and M2 disappear and a voltage is developed at a terminal M2 to turn off the TRs Q2-Q4 while turning off TRs Q5-Q5, thereby stopping the motor by applying an electric generation brake. Further, TRs Q5 and Q1 turn off to stop electricity feed to the AF.
