Title: Structure of drilling tube for improving ground
Inventor: TEOMO SHIYUUICHI
IPC: E02D3/12
Filed: 1982-09-10
Abstract: PURPOSE:To drill a pit in sandy layer without roughening the pit by a method in which a cam provided to the basal end of a tamping ram loosely provided to the outer tube of the drilling tube is coupled with the corresponding cam of the outer tube, and a wedge body is provided to the tip of the ram in a not- turning but forwarding manner. CONSTITUTION:While being turned, a drilling tube 4 is penetrated into the ground to be improved under a static pressure applied. When the ground is hard, a wedge body 23 is pressed into the outer tube 13 under the soil pressure against a spring, and the drilling of a pit is made by a bit 12. When a sand and gravel layer is reached, the soil pressure is lowered, and the sedge body 23 is projected to the front side of the bit 12 by means of a spring. At the same time, a claw body 22 is penetrated into the sand and gravel layer to stop the sotation of the outer tube and the ram 14 is also stopped through a stopper bolt 24. The cam 18 fixed to the outer tube 14 acts on the cam 16 of the ram 14 to move it vertically and continuously in the direction of arrow. A pit is drilled without roughening the pit while tamping the sand and gravel layer 27.

Title: Forced cooling light emitting diode device
Inventor: NOGUCHI MASAHIRO
IPC: H01L23/473
Filed: 1992-06-16
Abstract: PURPOSE:To obtain a light emitting diode device having high-power and allowing high-power drive by driving a light emitting diode under a forced cooling condition. CONSTITUTION:Providing a space between a heat-insulating case 1 and a cooling case 3 to be housed in the inside thereof for being filled with a heat-insulating material is more suitable and keeping the space in a vacuum is the most suitable because in this way the heat-insulating property is enhanced and transmission of light is not disturbed. Besides a window 2 is not required when the heat- insulating case 1 is composed of a material having an excellent light transmission property such as glass. Then, a cooling case 3 is housed in the inside of the heat insulating case 1 to be heat-insulated from outside so that at least one face is required to be light transmitting in order to take out generated light to the outside and its inside is desirably to be cooled not exceeding -10 deg. by a cooling agent. Accordingly, when the cooling agent is introduced from a lead-in tube 4 to the cooling case 3 to cool a light emitting diode and to be discharged from a discharge tube 5 outside the heat insulating case, light emitting output is remarkably improved so as to make it hard to be saturated while also reducing the spectrum width.

Abstract: PURPOSE:To provide a hole cup which can produce any other louder and rhythmical sound than a pleasant sound at a time of hole-in by installing inside the hole cup a sound device generating a large sound by sensing sound or vibration of a dropping ball. CONSTITUTION:A hole cup is assembled by a cup body 1, a ball receiver 3 and a sound device 5, all being disassemble. The sound device 5 is arranged on a calyx plate 23 fixed to a mounting stand 31 and formed of a speaker 25, a cell 27 to supply power to the speaker 25 and a sensor 29 to send an electric signal to an electric circuit. A sound collecting microphone is used as the sensor 29.

When a switch circuit is started, a voice circuit in the speaker 25 is operated to generate a voice in a chirp of birds which goes out of the speaker 25. Thus, even if the hole is too distant from a place where the ball is striken to hear the ball dropping sound, the sound thus amplified can be heard without fail.
