Title: Polishing jig and polishing of low-hardness compound semiconductor crystal
Inventor: SHIOTANI TAKASHI
IPC: H01L21/304
Filed: 1988-06-27
Abstract: PURPOSE:To polish a compound semiconductor crystal in a uniform thickness without damaging it by a method wherein a micrometer is fixed to an outer piece having a smooth lower-end face and a circular bore in such a way that its movable tip part protrudes in the circular bore and a smooth lower-end face on a plane identical to the smooth lower-end face of the outer piece and a central piece having an outside diameter fitting the circular bore are fixed to the movable tip part. CONSTITUTION:When a compound semiconductor crystal 18 is situated at a large distance from a polishing plate 20 and is in a positional relationship that a polishing powder 22 does not reach the compound semiconductor crystal 18, the compound semiconductor crystal 18 is not polished. When the compound semiconductor crystal 18 comes into contact with the polishing plate 20, the compound semiconductor 18 is polished; since the compound semiconductor crystal 18 is of low hardness, it is subjected easily to damage such as a strain or the like. Therefore, the compound, semiconductor crystal 18 and the polishing plate 20 are set in such a way that an extremely slight gap exists between them and that this gap is filled with the polishing powder 22. Thereby, the compound semiconductor crystal 18 is not subjected directly to a pressure from the polishing plate, 20; it is subjected to a pressure from the polishing powder 22 which is flowing and moving. The crystal can be polished sufficiently under the pressure of this degree and is hardly subjected to the damage such as the strain or the like.

Title: Tuned vibration absorber
Inventor: KOOTONII DEII JIEEMUZU
IPC: H02K11/00
Filed: 1995-06-23
Abstract: PURPOSE: To provide an AC motor having a minimum speed error. CONSTITUTION: A tuned vibration-absorbing device 30 is installed to the motor armature of an AC synchronous motor 20. The synchronous vibration-absorbing device prevents a resonance which significantly reduces the 120 Hz angular deviation perturbation of the AC motor. The synchronous vibration-absorbing device has a hub which is adhered to the armature of the AC motor. An inertia ring is connected to the hub through a spoke. The spoke and the inertia ring provide twist resonance to the motor and reduces an angular velocity error generated due to the AC motor. The motor can be used for a digital printing device which operates under harsh operation conditions.

Title: Dry treatment of oil-permeating electric apparatus
Inventor: KISHI AKIO
IPC: H01F41/00
Filed: 1988-06-28
Abstract: PURPOSE:To hold dryness degree of a winding wire group and contrive the reduction of the number of times of drying of an apparatus till a pack material is released by enclosing gas such as SF6 gas in the inside of the pack material for airtightly covering dried and oil-permeated winding wire groups. CONSTITUTION:Winding wire groups in a winding wire assembling process 11 are covered by a pack material which can airtightly be isolated from the outside air in a pack material setting process 12. The winding wire groups in an iron core piling process can be protected from absorbing moisture by enclosing SF6 gas 14 in the inside of the pack material after drying and oil- permeating 13. Next, after an outside assembling process 15, packing is released 16 and a test 18 is performed through degassing and deoiling processes 17. Since paper insulating material included in the winding wire groups is protected from absorbing moisture as long as the pack material is not released, its dryness is held for a long time when they are dried once. Thereby the number of times of drying of an apparatus can be reduced.

IPC: H01R13/453
Filed: 1995-05-31
Abstract: PURPOSE: To prevent a fire due to a leak caused by the moistured dust adhering to the plug-in blades in the state that the plug-in blades of an electric power plug are plugged in an outlet. CONSTITUTION: Plug-in blades 2 plugged in an outlet are provided in the frame body 1 of an electric power plug, a cover 3 for covering the plug-in blade 2 side of the frame body 1 and an elastic bellows-form cover 4 made into one body with the cover 3 is provided in the periphery of the plug-in blades 2.

Title: Rope tensioner
Inventor: TAKAMORI SHIGERU
IPC: A62B35/00
Filed: 1987-06-24
Abstract: PURPOSE:To make even unskilled laboe possible to engage a rope in the desired tensility by making the rope so as to come into the desired tensility with a free end of the rope pulled only, in case of a rope tensioner to be used as a stretcher for a parent rope at construction work or the like. CONSTITUTION:The tip of a rope 8 being drawn out of a rope guide member 6 is engaged with another holddown member 9. And, when the rope 8 is pulled, it is tensible between these holddown members 9 and 10. The backstop lever 4 keeps the rope 8 in tensility as its engaging pawl 4a is bitten into a peripheral surface of the rope 8, checking delivery of the rope 8 in the slacking direction. Especially, since pawl teeth are superposed on each other with some lost motion zigzag, the engaging pawl 4a is surely bitten into irregularities of the rope 8, thus its stopping force is improvable. In this connection, some irregularities are formed on a groove bottom of a pulley 2, thereby making the rope 8 hand to slip.
