Title: State transition control system
Inventor: YOKOTA HARUO
IPC: G05B13/00
Filed: 1987-12-23
Abstract: PURPOSE:To reduce processing cost in a state transition control system by showing each of produced states in the form of the differential from the initial state for the control of the state transition as well as in the form of a state control process which handles the information shown in the differential from the initial state. CONSTITUTION:The differential generated by the transition to a state S22 due to the application of a function element b:q r is obtained from a state S11 since the preceding states of both states S11 and S22 are equal to an initial state S0 respectively. The differential from the preceding states S11 is equal to -on(q, b), +on(r, b), -clear(r) and +clear (q) respectively. The synthetic differential between these differentials and the preceding state S11 is equal to -on(a, b), +on(q, b), -clear(q) and +clear(a) respectively. Then the synthetic differential of the state S22 is equal to -on(a, b), +on(r, b), -clear(r) and +clear(a) respectively. Thus each state is always shown in the differential from the initial state so that the quantity of data processed in a state transition state is extremely decreased together with reduction of the cost.

Patent JP-H02171596-A (JP)
Title: Heat exchanger with fins
Inventor: KUSUHARA HISAO
IPC: F28F1/32
Filed: 1988-12-23
Abstract: PURPOSE:To improve ventilation resistance when fins are used at an evaporator and to improve heat exchanging performance by providing the fins disposed being cut and raised at both front and rear faces with respect to fins base in one row of a gas flow outlet side and selectively disposed cut and raised at one side of front or rear face in other plurality of rows. CONSTITUTION:Cut and raised parts 5a - 10c of a heat exchanger with fins are disposed perpendicularly to an air flowing direction A, and cut and raised alternately at an equal interval at both front and rear faces along an air flow with respect to the fin base face in the row of a gas flow outlet side. On the contrary, cut and raised parts are cut and raised only at front side of the air flow outlet side in the row of the air flow inlet side. When the heat exchanger with the fins composed in this manner is used as an evaporator, water droplet adhered to the surface of the fin is not held by the cut and raised part in the row of the air flow inlet side, and its ventilation resistance is low. Thus, the decrease in its windage is small, and the reduction in the heat exchanging capacity is small. Since the number of the cut and raised parts is large at the air flow outlet side, its heat transfer rate is enhanced that much by the leading edge effect of a boundary layer.

Title: Oval cylinder bending type transducer
Inventor: SUZUKI MASASHI
IPC: G01S7/521
Filed: 1987-12-25
Abstract: PURPOSE:To simplify the adjustment of a compression force, by providing an oval cylinder with a bolt for adjusting a compression stress piercing it in the direction of the long axis thereof. CONSTITUTION:When a bolt 50 is turned in the direction of the arrow C from outside an oval cylinder 1, a tightening force of the bolt 50 and a nut 51 works evenly as compression force A on a piezo-electric element block 1 through a step of a through hole 16 of the oval cylinder 1 and a spacer 23. Thus, as compared with the conventional oval cylinder bending type transducer, in which a keep plate with a bolt and a nut screwed into the bolt of the keep plate are arranged within the oval cylinder 1, this eliminates the need for removing and mounting a flange, thereby simplifying adjusting work of a compression force A for the piezo-electric block 2.
