Title: Package and its mounting unit
Inventor: SAITO TAKEO
IPC: H05K7/14
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent falling from a guide rail and to achieve a smooth pull-out and insertion by providing a plate material for preventing warpages with a part for increasing a sectional secondary moment, while being formed in a step along a direction where a package is inserted at the upper and lower side edge parts of the package. SOLUTION: In a mounting unit, a package 4 is inserted toward the side of a back board 3 from an opening side, while a sidewall part 11B of a plate material 11 for preventing upper and lower warpages is brought into contact with a guide rail 5 and guided. When it is inserted into a specific position, a connector 6 makes contact with a connector 2. When it is inserted further, both the connectors 2 and 6 are connected with each other and mounting to a specific position is completed. Then, since a step part 11A formed along a direction where the package 4 is inserted into the plate material 11 for preventing warpages, the sectional secondary moment of the plate material 11 for preventing warpages increases due to the step part. Therefore, weight can be reduced by using the plate material 11 with a small thickness.

Title: Rear wheel steering angle control device for four-wheel steering vehicle
Inventor: KAWABE TAKETOSHI
IPC: B62D7/14
Filed: 1989-09-26
Abstract: PURPOSE:To ensure proper safety travel by fixing a steering angle limiting pin at a position relative to a steering angle limiting groove during a braking operation, and limiting a rear wheel steering angle to a steering amount at a braking start, even when a rear wheel steering angle control system fails upon braking slip during a high speed travel. CONSTITUTION:The more is the speed of a propeller shaft 10, the larger is a centrifugal force acting on a weight 13, and this weight 13 radially moves correspondingly to balance with an energizing force by a spring 16. Consequently, a steering angle limiting pin 17 comes to be located at a lower position as a vehicle speed rises, and a charge on a steering angle limiting groove 18 becomes large. Also, the larger is a charge on the aforesaid groove 18, the rod 6a of a rear wheel steering power cylinder 6 is subjected to the more limitation by the stroke range thereof, thereby giving a steering angle limit to a rear wheel 3. At the time of a braking operation, brake fluid pressure generated by a master cylinder works to press a piston 102 to the side of the steering angle limiting pin 17, and the charge of the pin 17 on the aforesaid groove 15 is thereby maintained at the same level as at a braking start.

SOLUTION: A PET film 1 having 10μm thickness is mounted in an ion- assisted oblique vapor deposition device and the film 1 is travelled at 2m/min travelling speed. A Mg oxide crucible 15 is filled with Fe 16, which is vaporized by using a 30-kW electron gun 17 to deposit Fe vapor on the PET film 1. Further, methane and oxygen are supplied to a 400-W output ion gun 19 to irradiate the Fe film on the film 1 with carbon ion and oxygen ion to obtain a magnetic tape for VTR having 1850Å thickness of the magnetic film, 1400Oe coercive force Hc, 5300 G saturation magnetic flux density Bs, and Br/Bs=0.86. Thus, the obtd. Fe-C-O magnetic film has an oblique columnar structure on the base body and the carbon density and the oxygen density are made higher in the peripheral part than that in the center part of the magnetic column.  The obtd. medium has excellent corrosion resistance and durability.

Title: Transfer device for hot forging work
Inventor: TOMINAGA KOJI
IPC: B21J13/10
Filed: 1991-09-30
Abstract: PURPOSE:To refrain the temperature of a work from lowering when it is transferred from a furnace to a die at a time of hot forging. CONSTITUTION:The work 1 transferred from the furnace 31 is image picked up by an infrared camera 41 to detect the posture of the work 1. A computer requires the angular difference between the detected posture and the prescribed posture. The work 1 is moved by a handling robot 42 controlled by this computer to the die 6. In the meantime, the work 1 is rotated so that this angular difference is corrected by the handling robot 42 to adjust the posture of this work 1. The work 1 is transferred into the die 6 at an accurate posture. When the posture of the work 1 is adjusted, the heat radiation of the work 1 is reduced. The transfer time, too, can be reduced in comparison with the time required when adjustment of the posture of the work 1 and transfer to the die 6 are performed separately.

Title: Contactless rotary pump
Inventor: KITAMURA SHUICHI
IPC: F04C2/20
Filed: 1989-09-29
Abstract: PURPOSE:To improve the overall adiabatic efficiency by flowing the fluid in a space pinched by the vane side surface of the advancing side of one rotor and a part near the lagging end of the vane peripheral surface of the other rotor and a fixed central member into the discharging side space in the fixed central member. CONSTITUTION:The fluid in a space (an actuation chamber 7 under the condition that the tip of a line C2 comes to close a line C3) pinched by the vane side surface (a part corresponding to the line C2) of the advancing side of one rotor and a part near the lagging end of the vane peripheral surface 2' of the other rotor and a fixed central member 5 is flowed into the discharging side space in the fixed central member 5 through a discharging side communicating port 11 with the rotation of rotors 3, 3'. The fluid resistance at the time that the fluid in the actuation chamber 7 is pushed out to the outside is therefore never increased even if a clearance between the tip of the line C2 and the line C3 is contracted to about 1mm. Consequently, since a closed space can be reduced more, the overall adiabatic efficiency is improved remarkably, and an energy source for generating the noise is made small and the noise is restrained.

Title: Winding control method of yarn
Inventor: HASHIMOTO KINZO
IPC: B65H54/74
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of bulge winding and to improve a package form by making a control method consisting of an initial stage to start winding an end of a twill angle suddenly increasing or of a high twill angle and a later stage up to the end of winding while gradually decreasing the twill angle thereafter. SOLUTION: A bobbin 2 is installed on a bobbin holder 1, it is integrally rotated with the bobbin holder 1, and yarn is taken up on the bobbin 2. A touch roller 3 makes contact with an outer periphery of the bobbin 2 by specified bearing and it is rotated. The yarn is traversed by reciprocating a traverse guide 5 by rotation of a traverse cam 4 on the opposite side of the touch roller 3. At a winding initial stage where a diameter of a package is up to 84-103mm, a twill angle is linearly and speedily increased up to about 8-14 deg.. Thereafter, at a winding later stage up to 103-250mm, the number of rotation of the traverse cam 4 is controlled so that it gradually decreases in a parabolic shape projected downward until the twill angle of about 14-16 deg.. Both of bulge winding and a high selvedge phenomenon these are prevented so as to provide a favourable package form.

Title: Optical fiber coupler
Inventor: OKAMURA KOJI
IPC: G02B6/28
Filed: 1987-10-06
Abstract: PURPOSE:To provide an optical fiber coupler which is small in insertion loss and is easily producible by partially heating and stretching a multi-core fibers having plural cores. CONSTITUTION:The multi-core fiber 2 which has the plural cores 1 in parallel in the axial direction is partially heated and stretched, by which the optical coupler function can be provided to said fiber at the branching ratio corresponding to the shape of the stretched part. Namely, such function is obtd., as the distance between the cores 1 in the stretched part decreases approximately similarly with respect to the inter-core distance in the other part and the coupling of light power is thereby generated. Since there is no need for generating a twist in the core part in this case, the increase in the insertion loss by the twist is prevented. In addition, the need for the operation of welding the optical fibers in the state of maintaining the tight contact of the optical fibers with each other is eliminated and, therefore, the production thereof is easy.

Abstract: PURPOSE:To attain efficient radio communication between a base station and a mobile station by selecting the direction of a communication beam in a direction in which a signal with a highest electric field strength is received at a point where a scanning means scanning surroundings intermittently is located. CONSTITUTION:A base station 101 executes scanning by a major beam in every direction in tow-dimension or stereoscopically by changing the directivity of an antenna mechanically or electrically intermittently, in response to the transmission rate concretely such as every 5msec in the case of 200kbps. A mobile station 107 receives the major beam and measures the electric field strength at a received point and informs the result of measurement to the base station 101, which fixes its direction of the major beam in a direction in which a signal with a highest electric field strength is received afterward. Thus, a new radio wave transmission channel Bb is found out corresponding to the reception environment of the mobile station 107 and the direction of the major beam is corrected. Furthermore, when the direction of the antenna is electrically changed, for example, a phased array antenna or the like is used.
