Title: Heat transfer tube
Inventor: YAMAMOTO KOJI
IPC: F28F1/40
Filed: 1989-12-13
Abstract: PURPOSE:To improve the heat transfer performance by repeatedly forming protrusions of predetermined length each having an oblique part between grooves in a steplike state, and repeatedly forming oblique surfaces inclined reversely to the oblique part of the protrusion on the bottom of the respective grooves longitudinally in a steplike state. CONSTITUTION:Protrusions 3 each having an oblique part 31 in a predetermined direction are repeatedly formed between grooves 2, and the bottoms of the grooves 2 are formed to be uneven having oblique surfaces 21 reversely thereto. The relationship between a difference H between the maximum thickness Tmax of the protrusion at the upward oblique end of the protrusion 3 and the minimum thickness tmin of the groove at the down oblique end of the groove 2, and a difference (h) between the minimum thickness Tmin of the protrusion at the downward oblique end of the protrusion 3 and the maximum thickness tmax of the groove at the upward oblique end of the groove, is set to satisfy H-h/H<=0.6. Thus, an increase in pressure drop in a tube at the oblique parts and surfaces is prevented, and heat transfer performance of the protrusions 3 and the uneven part is improved.

Title: Bolt connecting splice plate
Inventor: WATABE YOSHIYUKI
IPC: F16B43/00
Filed: 1994-12-26
Abstract: PURPOSE: To improve connection resistance by applying a steel mesh having strength higher than that of a connected mother steel plate to a plate surface, and thereby attaining a high sliding coefficient on a frictional connection surface of a high power bolt. CONSTITUTION: The stronger steel wire is, the higher the frictional resistance is. The steel wire necessarily has hardness higher than that of a lowermost connected steel plate 1 and a splice plate 2. The hardness ranges between twice of the steel plate 1 and eight times of the steel plate 1, only by improving friction as biting anchor effect of the steal wire due to bolt fastening. A diameter of the steel wire may be not less than 0.2mm in order to secure surface roughness through blasting treatment. A sliding coefficient is dependent on roughness and hardness of a frictional connection surface. The frictional coefficient is saturated or lowered in the case of excessive wire diameter and roughness, so that the wire diameter is not more than 1.0mm. The roughness of the frictional connection surface is influenced by mesh, which is preferably not more than 100 mesh.  Connection strength of the steel mesh must be a value which is only enough not to escape. It is thus possible to easily obtain a high and stable sliding coefficient.

Title: Load controller
Inventor: NAMIKOSHI YASUMASA
IPC: H05B37/03
Filed: 1987-12-21
Abstract: PURPOSE:To detect the operation state of a load with a simple constitution by connecting a first resistance and a first transistor TR in series to a DC power source and applying a voltage to the base of the first TR through a second resistance to keep the load current at a preliminarily determined value and discriminating the level of the voltage between both ends of the second resistance. CONSTITUTION:A display screen consists of n-number of discharge lamps L1-Ln, and these discharge lamps L1-Ln are selectively lit to display an image. For example, a first resistance R11 and an PNP TR Q11 are connected in series to the discharge lamp L1, and they are connected to a DC power source E1 for discharge through a line 3. Power is supplied to a control circuit 4 from a DC power source E2 for control, and this control circuit 4 keeps the base voltage of the TR Q11 constant through a second resistance R21 so that a preliminarily determined load current flows to the discharge lamp L1. The level of the voltage between both ends of the second resistance R21 is discriminated. Thus, the operation state of the load is detected with the simple constitution.
