Title: Dry developing device
Inventor: IKEDA TAKASHI
IPC: G03G15/08
Filed: 1982-03-12
Abstract: PURPOSE:To prevent the scattering of toners from a casing, by closing the clearance between the top end part of the casing and a photosensitive drum with a sealing material, spacing the root end part of the blade on a developing roll from the casing surface and forming a reflux passage for the toners. CONSTITUTION:The clearance formed between the top end part of a casing 7 of a dry developing device contg. a developing roll 5 and a scooping roll 6 and a photosensitive drum 1 is closed with a sealing material 16, and a blade 110 which regulates the thickness of the tone layer on the developing roll is mounted integrally with the side plate of the casing by a shaft 110J penetrating through the root end part, whereby a toner reflux passage 111 is formed. The internal pressure in the hermetic space is thus reduced, and the leakage of the toners into the spacing between the bottom part of the casing 7 and the drum 1 is eliminated. The broken lines in the figure indicate the flowing route of the toners after the passage 111 is provided. As a result, the scattering of the toners from the casing 7 is prevented.

Title: Socket for fastening tool
Inventor: UENO KANJI
IPC: B25B21/00
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent falling of a socket in fastening in the lower direction by providing a hexagonal head at one end of a main body and mounting a synthetic resin cover with flexibility to surround this hexagonal head and to hold the tip part of a socket with hexagonal hole which is mounted on the rotary shaft of a fastening tool. SOLUTION: A hexagonal head 1a of a main body 1 is fitted into a hexagonal hole at the tip part of a socket 6 with hexagonal hole mounted on the rotary shaft 5 of a fastening tool 4. Because a synthetic resin cover 3 holds the tip part of the socket 6 with hexagonal hole in a state that the hexagonal head 1a is mounted on the tip part of the socket 6 with hexagonal hole, the socket 6 does not fall also when a fastening in the lower direction is performed. Further, the synthetic resin cover 3 corrects the axial deviation of a socket for fastening tool from the rotary shaft 5 because the cover 3 holds the tip part of the socket 6 with hexagonal hole from the surrounding.

Title: Positional calibration of head for installing electronic component
Inventor: TOMITA MASAMICHI
IPC: H05K13/04
Filed: 1988-02-24
Abstract: PURPOSE:To confirm a component attaching accuracy substantially similar to that of a single head, by a method wherein in both an inspection station and a component attaching station, difference vectors of position vectors of respective heads with respect to respective positioning reference points are previously obtained, and a position correction value characteristic to each position of the head is set. CONSTITUTION:An electronic component 8 is sucked to the head section of a head 7 in a such station 2. In this connection, it is assumed that an error P2 exists between the center position of the component 8 and a positioning reference line 2-2. When the head 7 reaches a rough positioning station 3, a rough positioning device corrects the position of the component 8 to decrease the position error to P3. Next, in reaching an inspection station 4, the image of the component 8 is picked up by means of a camera 9 which is disposed on a positioning reference line which is approximately located just under both the head 7 and the component 8. The image applied to the camera 9 is then focused on an image pickup device 10, and the displacement in the position of the component 8 from a reference vertical line in the inspection station 4 is observed on the basis of both a predetermined electrical processing and a mathematical operation to obtain a displacement of P4 in value. Finally, in an attaching station 5, the head 7 is moved downward, and then attached to a board 11 to which components are to be attached with a decreased error P5.

Title: Flow control device for power steering equipment
Inventor: YAMAMOTO MASAJI
IPC: B62D5/06
Filed: 1984-02-29
Abstract: PURPOSE:To prevent change in flow characteristics at low temperature by forming the second orifices which are inserted inside a passage connecting to a power steering device with small holes, and closing either one of the small holes at normal temperature and opening it at low temperature. CONSTITUTION:Flow fluid supplied from a supply passage 12 is supplied to the first valve room 32 through a control throttle 31 and then supplied to a power steering device from ejection port 21a of union 21 via a flow hole 23a and each of orifices 24a, 24b. In this case, when the temperature of flow liquid is low and viscosity of the fluid is high, difference in pressure between the front and rear of a control throttle 31 is caused due to increased throttle resistance of the control throttle 31, allowing a control spool 23 to slide and closing the first orifice 24a. Therefore, a control member 35, which consists of bimetal, selectively opens and closes either one of the multiple, small holes H1-H6. Decrease in flow rate caused by closing the first orifice 24a is then compensated for with increase of opening area of the second orifice 24b.

IPC: G02B6/00
Filed: 1978-04-04
Abstract: PURPOSE:The bulk density of porous preform is kept in a specific range and the preform is made to transparent glass in helium gas containing halogen or halide gases, thus lowering the water content remaining in the parent material as low as possible and keeping the absorption loss low. CONSTITUTION:Porous preform 16 is grown by blowing fine particles formed in burners 10 and 12 to the lower end of base material 14 which is made to rotate and gradually lifted up. The rate of argon fed to burners 10 and 12 is controlled to form preform of 0.15-0.35 g/cm<3> bulk density. The preform is sent to furnace 24 for making transparent glass with preventing the gases from mixing by separator 22. As furnace 24, is used a muffle furnace and a mixture of halogen and helium gases is fed to inside of the furnace. As halogen gas can be readily introduced to the inside, hydroxyl groups are throughly substituted with halogen ion, thus lowering the absorption loss caused by hydroxyl groups to less than 1.5 dB/Km.

Title: Paper feeder
Inventor: OUCHI TOSHIAKI
IPC: B65H3/52
Filed: 1988-02-24
Abstract: PURPOSE:To enable friction force, generated between paired paper feed rollers, to be always held to a fixed value by providing a resilient action means which resiliently presses the one paper feed roller of the paired paper feed rollers to the other paper feed roller. CONSTITUTION:Copying paper P is delivered from a feed roller 4 and a separator roller 5, when the feed roller 4 tends to move in a direction of separating from the separator roller 5 when the copying paper P is fed to paired resist rollers 10, a leaf spring 31, forced to come into press contact with a rotary shaft 12, flexes increasing the resilient force of the spring and a load applied to the rotary shaft 12. Accordingly, in case of feeding the copying paper P to the paired resist rollers 10, even when force in the direction of separating from the separator roller 5 acts on the feed roller 4, the force is absorbed by the resilient force of the leaf spring 31, and the feed roller 4 is prevented from moving. In this way, the copying paper P is always normally fed to a side of the paired resist rollers 10 by friction force generated between the feed roller 4 and the separator roller 5, being prevented from generating an improper paper feed of jam or the like.
