Title: Non-stage transmission for bicycle
Inventor: HASEGAWA KYOHEI
IPC: B62M3/06
Filed: 1987-09-28
Abstract: PURPOSE: To prevent pulsation of transmission force by providing a receiving body to be rotatable by a first pivotal support part on one of an input and an output side rotation member, and rotatably providing a ratchet body by a second pivotal support part on the receiving part. CONSTITUTION: A ratchet claw 13 comprises a receiving body 13A rotatable about a support point of a pivotal shaft 15, and a ratchet body 13B rotatable about a support point of a pivotal shaft 15A provided on it. As the ratchet claw 13 advances in a drive zone D, therefore, the ratchet body 13B is separately inclined to the receiving body 13A along a tangent direction of a ratchet gear 29. A timing when inclination angle difference α between the ratchet body 13B and the receiving body 13A becomes similar on the entrance side and the exit side of the drive zone D is thus passed. Speed difference between plural ratchet claws 13DR in the drive zone D thus becomes small, thereby pulsation of transmission force can be restricted.

Title: Production of amorphous alloy powder
Inventor: YOSHIZAWA KATSUTO
IPC: B22F9/04
Filed: 1986-10-14
Abstract: PURPOSE:To easily produce powder whose density is easily increased when used to produce an amorphous bulk body or a compressed powder core, by cooling an amorphous alloy produced by a method for rapidly cooling a melt to a temp. below room temp. and by crushing the cooled alloy. CONSTITUTION:An amorphous alloy is produced by a method for rapidly cooling a melt such as a single roll method, a twin roll method, centrifugal rapid cooling or spinning in a rotating liq. Since the amorphous alloy is so ductile that the alloy is not readily broken by bending, it is difficult to mechanically crush the alloy. When the alloy is cooled to a temp. below room temp., especially to <=-150 deg.C, the alloy is liable to embrittle and is easily crushed. When amorphous alloy powder produced by cooling and crushing the amorphous alloy is heated to room temp., the powder becomes ductile. The particles of the powder are easily bonded to each other when the powder is used as starting material for producing an amorphous bulk body. The density of the powder is easily increased in case of a compressed powder core.

Title: Microphone device
Inventor: MIURA KATSUNORI
IPC: H04R3/00
Filed: 1989-09-20
Abstract: PURPOSE:To reduce wind noise and to sufficiently secure a low frequency range, directivity, etc., in a windless condition by connecting a high pass filter(HPF) in accordance with a difference between the output levels of an unidirectional microphone and a non-directional microphone. CONSTITUTION:The microphone device is provided with the unidirectional microphone 1 for outputting the 1st acoustic signal, the non-directional microphone 2 for outputting the 2nd acoustic signal, a correcting means 3, the 1st detecting means 6 for detecting the output level of the 1st acoustic signal, the 2nd detecting means 7 for detecting the output level of a correction signal, a comparing means 8 for comparing both the output levels, and a control means 12 for connecting the HPF 10 to an acoustic output terminal 13 in response to the detection signal. Since the single directivity microphone 1 is more easily influenced by wind noise as compared with the non-directional microphone 2, the superposition of wind noise to the microphone device can be detected when the 1st output level is higher than the 2nd output level. Thereby, noise can be cut out from an acoustic output signal by connecting the HPF 10 to the acoustic output terminal 13.

Title: Waterproof structure of electric connection box
Inventor: YAMAGUCHI TORU
IPC: H02G3/14
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To prevent water from penetrating inside an connection box and prevent water from adhering to a circuit board, electric components, etc., within a box by providing a waterproof skirt drooping continuously as well as surrounding the main body, around a receiving groove. SOLUTION: In the case that high-pressure water flow hits directly upon the waterproof skirt 9 of an electric connection box C attached to a vehicle, etc., the high-pressure water P is dispersed by the waterproof skirt part 9, and water pressure does not directly reach the butting part 10, because the butting part 10 between the main body A and the cover body B is positioned inside the waterproof skirt part 9. Even if the water pressure reaches the butting part 10, inflow of the water into the electric connection box C is checked, because the periphery of the main body A and the inner face of the waterproof skirt part 9 contact closely with each other. Hereby, the electric components, etc., within the box can be protected from water troubles.

Title: Steel pipe pile with tip diameter enlarged
Inventor: HOSOKAWA YOSHITAKA
IPC: E02D5/44
Filed: 1994-09-14
Abstract: PURPOSE: To heighten the strength by providing a steel pipe pile in its foremost area with a diametrically enlarged part in the form of a trumpet, truncated cone, etc., where the inside and outside diameters increase gradually toward the pile tip. CONSTITUTION: After excavation is made by an excavating head till a bearing layer, a solidifying material 11 is injected into the excavated hole, and the head is pulled up while mixing and agitation with the earth and sand of the bearing layer are performed. Then a steel pipe pile 1 is fitted by pressure into the excavated hole so that a blocking part 6 is formed where the hollow of the diametrically enlarged part 3 is filled with solidified soil. When a load (q) is applied from the ground to this blocking part 6 as the reaction force of the structure load, a component force (f) perpendicular to the inside surface of the diametrically enlarged part 3 is applied to the blocking part 6 as a pressing force. Besides the attaching force of concrete etc., the friction force due to this pressing force is applied to the joint surface of the blocking part 6 and diametrically enlarged part 3. This heightens the bonding strength between the tip blocking part and the inside surface of the pile and shortens the filling length of concrete etc.
