Title: Method for molding rotary type guide pin, and tape guide device having the rotary type guide pin
Inventor: KAWAKAMI KIKUJI
IPC: G11B15/60
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent video abnormality and edge damage by molding the rotating member of a rotary type guide pin from a resin contg. spherical particles at a prescribed content ratio so that the spherical particles precipitate on the outer peripheral surface. SOLUTION: The static friction force of the magnetic tape 4 guide surface of the rotary guide pin 7A and the tape 4 is a cause of trouble, such as video abnormality and edge damage, if this force is large. The pin 7A of the resin rotating member 8A is, therefore, molded by incorporating rigid spherical particles 16A of a metal having excellent wear resistance therein. External force, such as magnetic force or centrifugal force, is then applied thereon at the time of molding to precipitate the particles 16A on the surface of the cylindrical surface of the member 8A according to the range of optimum surface roughness, the grain size and the volumetric concn. thereof at the time of charging. Then, the pin is formed at a lower cost as compared with screw thread cutting and surface working by machining of the pin 7A having the resin member 8A or adoption of a metallic guide pin.  In addition, the static friction factor is lowered and the occurrence of the trouble is prevented.

Patent JP-H0520710-A (JP)
Title: Optical pickup device
Inventor: FURUHATA HITOSHI
IPC: G11B11/105
Filed: 1991-07-10
Abstract: PURPOSE:To reduce the influence of the double refraction of a disk board on the focusing and tracking error signals. CONSTITUTION:The focusing means 42 and 43 are provided to focus the reflected light sent from an optical recording medium together with a reflecting (transmitting) means 43 which reflects (transmits) partly the reflected light to supply it to a focusing/tracking error detector means 45 and leads the remaining reflected light to a polarizing means 44. Then the means 44 polarizes and separates the remaining reflected light led by the means 43 and supplies the separated light to a reproduced signal detector means 46. The outside part of the reflected light is not made incident on a photodetector and therefore an even distribution is secured for the received light quantity. Then no error is caused to the best focusing position and the track crossing noises are prevented regardless of the degree of the double refraction. Furthermore no offset is caused even though a beam moves on the photodetecting surface of the photodetector. At the same time, the mixture of the tracking errors can be reduced into the focusing error signal.

Title: Method for separating fine particle
Inventor: ISHIKAWA SATOYUKI
IPC: B04C5/14
Filed: 1995-06-13
Abstract: PURPOSE: To separate fine particles from powder efficiently and continuously by dispersing the powder in a cyclone by introducing air which forms a revolving current in the reverse direction to an air current in the cyclone from a receiver and entraining the fine particle in the powder on the discharged air current. CONSTITUTION: When a powder entraining air current is introduced from an air introduction port 11, and the second air current which forms a revolving current in the reverse direction to the first current is introduced from a receiver 14, the two currents collide with each other in the conical part 16 of a cyclone to disperse the entrained powder. In this process, the two currents in the opposite directions are competing in power. The particles in the cyclone follow different tracks on the surface of the inner wall corresponding to the particle sizes, etc., and collide with the second air current at different positions, and a critical particle size is changed by the revolving speeds of the particles and the second air current.  As the result of the collision, the particles below the critical particle size are dispersed to be discharged from a discharge opening 15 by an ascending current, while the particles greater than the critical particle size are collected by the receiver 14.

IPC: H04R7/02
Filed: 1981-10-23
Abstract: PURPOSE:To improve an internal loss of an audio device forming material made of the flaky graphite mixed with synthetic resin, by selecting the polyvinyl chloride and polynorbonane for the synthetic resin. CONSTITUTION:A material of an audio device is compounded with 60 polyvinyl chloride, 14 polynorbonane, 6 paraffin oil, 1 stearic acid and 160 flaky graphite respectively in terms of pts.wt. Such material is left 24hr at a room temperature, and as a result the paraffin oil is absorbed to the polynorbonane. Thus the glass transition point of polynorbonane is set at about 0 deg.C to obtain the high and stable elasticity for a loud speaker when it is used at a normal temperature. The polynorbonane which absorbed the paraffin oil is kneaded thoroughly with other compounding elements and then rolled repetitively. As a result, the flat surfaces of the flakes of the flaky graphite are orientated parallel to the plane of the rolled sheet material to obtain a high Young's modulus. Such sheet material is formed into a desired form by a vacuum forming process, etc. to obtain a loud speaker diaphragm.

Title: Manufacture of target surface plate for pickup tube
Inventor: YOSHINO TSUNEICHI
IPC: B29C65/18
Filed: 1981-10-27
Abstract: PURPOSE:To obtain relatively easily a traget surface plate for a pickup tube to which  a metallic pin for a video signal electrode is well airtightly sealed, by applying an  active metallic alloy principally consisting of Pb and Sn to the brimmed part of the metallic pin, and pressing them by means of a hot press while maintining the temperature lower than the melting point of the active metallic alloy so as to perform an  airtight sealing. CONSTITUTION:In manufacturing a target surface plate which has not any striped color-separation filter, a matter having a melting point of, for example, 226 deg.C is used  as an active metallic alloy 15. After a hot press consisting of a hot plate 16 and a  pressing jig 21 is heated with heaters to around 200 deg.C, which is slightly lower than  the above melting point, pressure is applied with the jig 21 as indicated by the arrow  (F). As a result, at a temperature of around 200 deg.C, the alloy 15 becomes in a semi- molten state, in which the solid phase and the liquid phase coexist. Here, when the  welding pressure is adjuted to 30-200kg per 1cm<3>, the alloy 15 undergoes a plastic  deformation, and part of the alloy 15 is pressed and fitted into a penetrating hole 12.  Next, a current is stopped from being fed to the heaters, and the alloy 15 is subjected  to a natural cooling while pressure is applied. By the means mentioned above, an airtightly sealed target surface plate can be obtained.
