Title: Speaker device
Inventor: FUJIHIRA MASAO
IPC: H04R9/02
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To increase a magnetic flux density acting on a voice coil without making a magnetic circuit large in size by increasing the magnetic flux density of a second magnetic gap part acting on the voice coil since the magnetic flux of a magnet for driving and the magnetic flux of the magnet for magnetic proof are passed through the second magnetic gap part. SOLUTION: In a magnetic circuit 5, the respective magnetic fluxes of the magnet 18 for driving and a cancellation magnet 19 are generated in the second magnetic gap part G2 and the magnetic flux density of the second magnetic gap part G2 is increased. Thus, the magnetic fluxes of the driving magnet 18 and the cancellation magnet 19 respectively act on the voice coil 16 inside the second magnetic gap G2. Then, for this speaker unit 1, resonance sharpness Q at a lowest resonance frequency is turned to about 0.5 and can be brought closer to 0.58. Thus, the speaker device 1 is small-sized, inexpensive and also extremely effective in terms of low frequency sound band reproduction.

Inventor: FUJINE MANABU
IPC: B22D19/00
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To facilitate mold releasing as a blocking means (dense inner peripheral part or recessed part) for blocking the arrival of molten metal at the outer periphery of a cylinder bore liner is formed in the inner peripheral part of a molding and, therefore, the molten metal does not arrive at the outer peripheral surface of the cylinder bore liner at the time of casting and consequently the shrinkage force of the inner peripheral surface of the molding is relieved at the time of casting. SOLUTION: This molding 1 is a molding 1 used for reinforcing the cylinder surface of a cylinder block made of a metal-base composite material (and) is formed with the inner peripheral part 1a of the molding 1 more densely than its outer peripheral part 1c or is formed with recessed parts for confining air in its inner peripheral part. This process for producing the molding 1 consists in producing the molding 1 by immersing and sucking a cylindrical member having air permeability into a slurry of a small size of the reinforcing material, then immersing and sucking the same into a slurry of a large size of the reinforcing material.  This process for producing the molding 1 consists in producing the molding 1 having the recessed parts by previously winding an inflammable porous member on the cylindrical member and immersing and sucking the same into a slurry of the reinforcing material, taking the member out of the slurry and burning out the inflammable porous member by firing.

Title: Method for adjusting optical axis of semiconductor laser optical fiber
Inventor: YOJIMA MASAYUKI
IPC: G02B6/42
Filed: 1989-05-17
Abstract: PURPOSE:To reduce the frictional resistance between holder contact surfaces and to equalize the quantity of the relative shift between holders by a rotating and vibrating the holders around the optical axis by a fine angle. CONSTITUTION:The semiconductor laser is held, a 1st holder 2 which has an end surface perpendicular to the optical axis and the optical fiber 6 are held, and the opposite end surface of a 2nd holder 7 having an end surface perpendicular to the optical axis is pressed in contact. Then while the holder 7 is rotated and vibrated around the optical axis at the fine angle, the holders 2 and 7 are positioned between the end surfaces so that the laser light output of the semiconductor laser which is transmitted through the optical fiber 6 becomes maximum. Consequently, the static friction is changed into dynamic friction to reduce the frictional resistance between the contact surfaces of the holders 2 and 7, and the fixed-side holder is not drawn by the moving-side holder because of the frictional resistance between the contact surfaces.

Title: Press
Inventor: BETSUSHIYO MICHIO
IPC: B30B15/18
Filed: 1979-09-27
Abstract: PURPOSE:To eliminate the defects of conventional presses and utilize driving power with good efficiency by lowering the revolving shaft of the eccentric body of a press device to the position near the pressure working surface to deviate the center of a revolving shaft from the axial line of the plunger. CONSTITUTION:The revolving shaft center 14 of eccentric body 2 body 2 of the press device is lowered to the position closer to the pressure working surface 13 than the point of coupling between a joining rod 3 and a plunger 5, that is, the position of a transmission pin 4, whereby the height of the entire part of the press is lowered. In addition, the rotating shaft center 14 is placed in the position deviated by a distance from the axial center in the reciprocating direction of the plunger 5, whereby the speed change is made slower near the lower dead point of the plunger 5 and te pressing work by a press ram 8 is normalized. At the same time, the length of the stroke from the upper dead point of the plunger 5 up to the lower dead point is large; therefore, in order to make the stroke same, the rotating radius R of the eccentric body 2 may be made small, thus the driving power can be small as well.

Abstract: PURPOSE: To provide a blocked cold trap with a self-regenerating function by a method wherein a heater for regeneration is installed to the cold trap in the system and a circulating route is formed including a gas-venting pot and a cold trap.  
     CONSTITUTION: A conventional device is equipped with circulating routes 21A, 21B. In a secondary cooling system at a fast breeder reactor, contaminated sodium hydride blocks a cold trap 12B. The cold trap 12B is kept at about 300°C or higher, and the sodium hydride is treated with the pressure of a solenoid pump 8 so that it is guided into a gas-vent pot 17 via piping 22B, 23. In the pot 17, the sodium hydride is decomposed by heating and is reduced in solubility to discharge hydrogen, which is removed. The sodium hydroxide, by being sucked by a solenoid valve 9B via piping 24, 19, 21B, is circulated into the cold trap 12B via economizer 11B. By repeating circulation to regenerate contaminated sodium, hydrogen is discharged and sodium is purified and regenerated step by step. At the completion of regeneration, the regeneration is switched to another cold trap 12A.

Title: Cooling system for rolled wire rod
Inventor: OGAWA RIKUROU
IPC: B21B45/02
Filed: 1977-10-18
Abstract: PURPOSE:To make possible the rolled wire rod with good drawa bility and strength to be manufactured efficiently, by detecting the resonance frequency from the resonance circuit arranged along the pass line of the rolled wire rod, by continuously measuring the temperature fluctuation of the wire rod, and by controlling the cooling so as to make this termperature fluctuation to coincide with the settled pattern. CONSTITUTION:The temperature of the rolled wire rod (a) continuously reduces by the cooler 1...N, and correspondingly to this, the impedance of individual temperature detector C varies stepwise; hereupon, the starting point Ps of the leading peak is corresponding to the transition point Acl of the rolled material (a). Accordingly, the controller F can detect the transition point as a result of the cooling of the rolled material (a), taking the output signal of individual temperature detector C as the input information. Then, the flow rate adjusting signal, necessary for making these cooling patterns obrained as above to coincide with the settled cooling pattern Q, is transmitted to individual flow control valve V, and hereby, the flow rate of the coolihg medium is controlled. According to this method, the transition point can easily, exactly detected, so that the cooling effect as compared to the lead bath can be accomplished without using the lead bath.
