Title: Intermittent feeder in press
Inventor: YAMAMURA YOSHINARI
IPC: B21D43/02
Filed: 1978-11-29
Abstract: PURPOSE: To expand a stopping angle range for clamping and unclamping up to 75° with less number of parts by letting a cam follower be slided in a stationary groove cam and moving groove cam by a crank and connecting rod thereby causing a feed bar to make intermittent motion.  
     CONSTITUTION: When a crank 1 revolves synchronously with a press drive shaft, a pin 2 makes circular motion about the axis 0 of the crank 1. The pin 3 pivotally fitted to a connecting rod 4 moves along a stationary groove cam 6 and at the same time the semi-circular moving groove cam 9 below a slider 8 also moves. When the pin 2 is at P 1 , the pin 3 is at the point Q 1  and when the pin 2 moves to P 2 , the pin 3 comes to the point Q 2 . When the pin 2 is at the unclamp mid-point, the pin 3 is in the position of M 2  while being guided by the cams 6, 9 and while the pin 2 is at the point P 3  from the point P 2 , the pin 3 slides between the cams 6, 9, during which time the slider 8 does not move, thus a stop angle 75° may be taken.

Title: Pitch extractor
Inventor: FUJII SHIGEKI
IPC: G10L25/90
Filed: 1988-06-16
Abstract: PURPOSE:To perform stable and smooth pitch extraction in a wide pitch range by first calculating the stability of inputted acoustic signals and, when the pitch extracted by a pitch extracting means shows an abrupt change, referring to the stability. CONSTITUTION:Inputted acoustic signals are first digitized by means of an A/D converter 1 and inputted to an EC calculating section 4. An EC value is the total sum of sample values of all sampling points existing between two continuous zero-crossing points in signals. The EC value is inversely proportional to the frequency, but proportional to the amplitude. The EC value is multiplied by the original digital signal outputs at a multiplier circuit 6 for calculating stability of the digital signals. The stability means the stability of a pitch extracting state and is used as a scale for measuring the reliability of extracted results. If the stability is high when a pitch abruptly changes, the pitch output is outputted to the outside. When the stability is low, on the other hand, the pitch is ignored and not outputted.

Abstract: PURPOSE: To concentrate a solution of lithium bromide easily by solar heat with no use of heat exchanger, by dividing the inner space of a case into two parts, i.e., an upper chamber having therein a solar-heat collecting plate which serves as a solution evaporating chamber and a lower chamber which serves as a solvent condensing chamber cooled by a water jacket.  
     CONSTITUTION: Temperature of a heat receiving plate 10 is raised by direct rays of the sun passed through a transparent, upper case 1, and diluting aqueous solution 8 supplied from a feed pipe 5 and dripped onto the surface of the plate 10 is heated and condensed at 11 while producing vapor 9. Then, the concentrate liquid is taken out from a liquid sump 23 via an outlet pipe 12. Here, since air does not exist in the upper case 1, pressure of the vapor 9 reaches the saturated vapor pressure determined by the temperature of the plate 10. Then, the vapor is passed into a lower case 2 through pores 20 in a heat-insulating plate 3 and cooled and condensed by cooling water in a water jacket 15, whereafter the condensate liquid is taken out from a liquid sump 27 via an outlet pipe 13. With such a simple arrangement utilizing the solar heat, it is enabled to carry out liquid concentrating operation with no use of heat exchanger.
