Abstract: PROBLEM TO BE SOLVED: To provide a high durable rooftop waterproof construction by laying a permeable concrete board, which is comprised of a porous hardening material molded by mixing at least aggregate and cement type binder, on a waterproofing layer arranged on a concrete slab. SOLUTION: A permeable concrete board 3 is composed of a high strength concrete layer 5 arranged on a permeable layer 4 of a porous hardening material molded by mixing at least aggregate and cement type binder. A waterproofing layer 2 of asphalt waterproofing material is formed on a concrete slab 1. Then, the permeable concrete board 3 is laid with keeping a joint part 6, being lightweight and non-adhesive of the board 3 improves execution property, and a danger of shear fracture by a concentrated load is obviated when a weightly equipment, such as building facilities and the like, is loaded. Therefore, a protection board for waterproofing is not likely to break so as to improve load capacity, and the waterproofing layer is not likely to be damaged to maintain long- term waterproof performance.

Title: Solid-state relay
Inventor: MINAMITAKE MASAYUKI
IPC: H03K17/78
Filed: 1985-11-08
Abstract: PURPOSE:To obtain a stable operation against the power supply fluctuation of an input voltage by applying a constant current or a constant voltage to a light emitting diode at the input side of a photocoupler isolating the control input side and the semiconductor switch element side electrically so as to attain the ON operation to a wide range of control input voltage. CONSTITUTION:When a control input voltage of a prescribed value or over is impressed to input terminals 51, 52, a prescribed current over a required light emitting drive current and below the rated current flows to a MOS transistor 11 and a light emitting diode 54 to obtain the ON operation. Further, the ON operation is attained to a wide range of control input voltage. Thus, even when the input voltage is fluctuated largely by the power fluctuation, since the current of the light emitting diode 54 is not fluctuated, the fluctuation of characteristic is less and the stable operation is obtained. Since a constant current flows to the light emitting diode 54, the fluctuation of characteristic due to secular change is less and the sensitivity of a photo thyristor coupler 53, and then the input sensitivity of a solid-state relay 10 is almost unchanged.

IPC: H01F41/04
Filed: 1988-10-04
Abstract: PURPOSE:To well connect laminated printed coils in series so as to automate the connecting works easily by providing a lead frame at about the middle height of the laminated body and making the projection of terminals longer as going upward and downward from the middle height. CONSTITUTION:Coil terminal sections 11, 12, and 21 on the upper side of a lead frame B are respectively welded to upper surfaces of each corresponding projecting section of the lead frame. On the other hand, coil terminal sections 22, 31, and 32 on the lower side of the lead frame are respectively welded to lower surfaces of each corresponding projecting section of the lead frame. While distances from each welded point to the root of the coil terminal section of each printed coil are not uniform, but the projecting lengths of the coil terminal sections are preset in accordance with the distances. Therefore, the coil terminal sections can be welded without applying any unreasonable stress to the coil terminal sections and producing any abnormal slackened part.

Title: Working method for end part of metallic pipe
Inventor: TAGAMI TOSHIHISA
IPC: B21D41/04
Filed: 1989-09-27
Abstract: PURPOSE:To work the pipe end to the objective measure and shape in a short time with high efficiency by clamping the metallic pipe from the peripheral direction, covering the upset punch having the inner conical working surface part and upsetting. CONSTITUTION:The metallic pipe 12 is fixed through the clamp 10 from the peripheral direction. The upset punch 18 is pressed to the metallic pipe 12 and executes upsetting. The stroke amount of straight motion and the stroke end position by the crank 10 mechanism is set so as to accord the metallic pipe 12 side base point 18B of the conical working surface 18A of the upset punch 18 with the reduced diameter base point 12A of the metallic pipe 12. Consequently the conical working surface 18A of the inside of the upset punch 18 has a spare room equivalent to (L1-L2) to the inside bottom and so the pipe and 12C to be worked of the metallic pipe 12 is not brought into contact with the inside bottom part of the upset punch 18, and so the increase of thickness does not occur. Therefore, the condition of the cold rolling by suppressing the work hardening is enlarged.

Title: Resin package type semiconductor device
Inventor: SATO HAJIME
IPC: H01L23/28
Filed: 1986-10-24
Abstract: PURPOSE:To prevent the occurrence of cracks in a package even if the effect of a heat history is received, in a resin packaged type semiconductor device, in which a semiconductor chip is fixed on the tab of a lead frame and resin packaging is performed, by specifying a ratio between the thickness of the packaging resin beneath the tab and the size of the tab to be 0.02 or more. CONSTITUTION:Many circuit elements are formed in a semiconductor element (chip) 2, and one circuit function is imparted. A thickness l of a packaging resin is a distance (mm) from the rear surface of a tab 3 to the bottom surface of a resin packaging part 10. A tab size A is a planar area (mm<2>) of the rear surface of the tab 3. The ratio between l and A is made to be L. The result of experiments regarding the relationship between L and crack yielding tempratures is shown in the Graph. It is found in the Graph that the occurrence of the cracks is prevented when the value of L is specified as 0.02 or more. The cracks are not yielded at the packaging temperature of 250 deg.C by specifying the value of L to be 0.02 or more. Even if the packaging temperature is made higher than conventional temperatures, the cracks are not yielded. Therefore, the speed of the packaging can be increased, and the yield rate of the devices can be improved.
