Patent JP-S63177494-A (JP)
Title: Multiple-wavelength light source
Inventor: TSUKADA NORIAKI
IPC: H01S5/187
Filed: 1987-01-17
Abstract: PURPOSE:To obtain a multiple-wavelength light source which can take out more than one laser beams from an identical region of a substrate by a simple structure and with good directivity by a method wherein the following are formed: more than one laser arranged on an identical substrate in different directions: a diffraction grating body formed in the identical region of the substrate by mutually piling up diffraction gratings corresponding to the lasers. CONSTITUTION:The following are formed: more than one distributed Bragg reflection laser A, B or distributed feedback laser, which is arranged on an identical substrate 1 in different directions; a diffraction grating body 3 which is formed in the identical region of said substrate 1 by mutually piling up diffraction gratings corresponding to said lasers A, B. For example, a beam of light radiated at a multiple-quantum-well layer 6 by injection of an electric current is multiple-reflected at a cleavage plane and at a diffraction grating, and is radiated as a laser beam from the cleavage plane and the diffraction grating. In order to take out one part of the laser beam from the diffraction grating in the vertical direction, the cycle of the diffraction grating is made identical to the wavelength of the laser. That is to say, the laser beam is fed back by a secondary diffraction effect, and, at the same time, one part of the laser beam is taken out by a primary diffraction effect in the vertical direction.

Title: Magnetic disk driving device
Inventor: SUGA TAKEYUKI
IPC: G11B21/12
Filed: 1990-01-18
Abstract: PURPOSE:To always hold a flexure at a constant position by mounting a flexure pressing part which presses the flexure in the direction of a magnetic disk at a supporting arm separately from a carriage arm which supports the flexure. CONSTITUTION:A flexure pressing member 10 returns a wire rod made of shape memory alloy to shape stored in advance by squeezing to V-shape and energizing the member 10. Then, the member 10 squeezes a bias flat spring 7 on the flexure 1, and the flat spring 7 is abutted via the flexure 1, which squeezes the flexure 1 to a magnetic disk 6 side. Next, after the flat spring 7 and the flexure 1 are squeezed to a prescribed position, the resultant force of positive pressure which pushes up the flexure from the disk 6 generated in a slider 3 and a force by which the flexure tries to separate the slider 3 from the disk 6 is generated. The slider 3 can keep a constant interval between the disk 6 where such resultant force is balanced with a force to pull the slider to the disk 6 with the negative pressure of the disk 6, and a stable floating state is kept without making the slider 3 bring into contact with the disk 6.

Abstract: PURPOSE:To increase heat recovery, enhance a coke cooling effect and save fuel without causing extinction of fire, by detecting compsn. etc. of a cooling gas entering a cooling tower from a boiler in a dry coke quenching installation and adjusting the amt. of air blown in. CONSTITUTION:A dry coke quenching installation is so constituted that red-hot coke fed at the top of a cooling tower 1 is cooled with a cooling gas and the high-temp. cooling gas having obtd. sensible heat of the red-hot coke is sent via a passage L1 and a dust collector 4 to a boiler d2, where heat is recovered by producing steam, and then circulated via a cyclone 5, a circulation fan 3 and a passage L2 to the cooling tower 1. Gas collected in a gas collector 9 installed in said passage L2 is introduced via a sample gas pipe line 10 to a gas analyzer 11, which detects components and compsn. of the gas and inputs a signal thereon to a dilution air flow controller 12. An opening signal is sent from the controller 12 to a flow controller 8 to adjust the amt. of flown air to be as much as possible within such a range that combustion of any combustible matter does not fail, minimizing combustible matter in the cooling gas. Thus heat recovery is enhanced.

Title: Liquid crystal display element
IPC: G02F1/1335
Filed: 1992-01-22
Abstract: PURPOSE:To prevent, without enlarging the shape of the liquid crystal display element, light from escaping outside a picture display part when a display plane is observed in a slanting direction, that is caused through irregular reflection or dispersion or the like by means of glass base inside and liquid crystal sealing material when the light radiated from a light source is slantingly incident on the liquid crystal display element. CONSTITUTION:Since tantalum 7 is printed on the periphery of a polarizing plate 4, no light is incident except out of the portion of a light source side polarizing plate 4. The light been incident in a slanting direction, is dispersed by means of the inside of a glass base 1 and liquid crystal sealing material 8, and is shaded by a display plane side polarizing plate 4 and the tantalum 7. Thereby no light escapses out even if the display plane is observed in the slanting direction.

Title: Resistive terminator
Inventor: TAKAMIZAWA HIDEO
IPC: H01F1/00
Filed: 1979-01-29
Abstract: PURPOSE: To obtain a resistive terminator by using a complex that contains magnetic metal powder, phenol resin and inorganic reflactories powder in a specific ratio by weight.  
     CONSTITUTION: When glass powder and acidic or alkaline refractories powder are mixed in phenol resin and magnetic metal powder such as Fe and Ni is combined with them, a substance the heat resistance of which is superior to phenol resin itself can be obtained, it can be used up to the Curie point in terms of characteristics and thermal property. It is more effective to mix 60% or less of refractories powder in the phenol resin by weight, a material that contains more than 60% refractories powder is inferior in moldability. Also a material that contains less than 10% metal powder by weight is magnetized little and is not suitable for miniaturization, another one that contains more than 90% metal powder cannot be used preactically because the mechanical strength is insufficient and the insulation resistance is less.

Title: Injection molding method
Inventor: YOSHIDA HIROMITSU
IPC: B29C45/26
Filed: 1995-01-24
Abstract: PURPOSE: To reduce the height of a gate mark while keeping pressure loss low by using a pin gate of which the leading end is formed into an oval shape. CONSTITUTION: A molten resin is injected into a cavity for a molded product from the leading end having an oval shape of a pin gate to be subjected to injection molding.

Title: Slip mechanism for rotational transmission device
Inventor: WATANABE TAKASHI
IPC: G11B15/26
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To stabilize supply of torque and drive of a tape by making a felt member and its fixing member have a high thermal conductivity and providing opening parts and cooling fins. SOLUTION: At the time of transmitting torque, when driving power is transmitted to a clutch 3 as an input gear, the driving power is transmitted via the felt member 5 to a clutch 6 as an output gear by frictional transmission between the felt member 5 and a groove part 6b of the clutch 6. The material of the member for fixing the felt member 5 of a torque generating component is specified as a material of higher thermal conductivity than resins. Then, the torque generating member and the member for fixing the felt member 5 are provided with the opening parts 3a and 6c and the cooling fins 3b and 6d. Frictional heat at the time of operating the slip mechanism during transmission of the driving power is radiated from the opening parts 3a and 6c of the clutches 3 and 6 or the cooling fins 3b and 6d.  Consequently, variation of the torque can be reduced, and the supply of the torque and the drive of the tape can thus be stabilized.
