Title: Zoom lens provided with tracking adjusting mechanism
Inventor: MURYOI TAKESHI
IPC: G02B7/02
Filed: 1984-12-04
Abstract: PURPOSE:To correct automatically movement of a back-focal distance by a temperature and a focal distance by calculating a moving extent of a racking lens from outputs of a temperature detecting means and a focus detecting means. CONSTITUTION:A temperature signal which has been detected by a temperature sensor 11 and amplified by a sensor use amplifier 12, and thereafter, A/D- converted by an A/D converter 5b is inputted to a microcomputer 16. ON the other hand, when a focal distance is detected by a zooming operating member 13 and a potentiometer 14, a zooming signal which has been A/D-converted by an A/D converter 15a is inputted to the microcomputer 16. A result of an operation of the microcomputer 16 is D/A-converted by a D/A converter 19 and amplified by an amplifier 20, and thereafter, a tracking lens is moved automatically by driving of a motor which is brought to a position control by a built-in encoder. IN this way, a focal movement generated by a temperature change is prevented, and even by zooming, no focal movement is generated.

IPC: G03G15/01
Filed: 1984-12-04
Abstract: PURPOSE:To make possible the exchange of developing devices without the need for an intricate change-over mechanism by disposing the 1st and 2nd developing devices to an image carrying body and constituting the developing devices in such a manner that the 1st developing device faces the image carrying body when the 2nd developing device is slid and parted from the image carrying body. CONSTITUTION:An electrostatic latent image is formed on a photosensitive drum 2 by illuminating a glass plate 1a by a light source 16. The 1st and 2nd developing devices 4, 4' are positioned to face the drum 2. The 1st developing device 4 is supported by the 1st holder 4a and the holder 4a is made freely turnable by a fulcrum shaft 43. The 2nd developing device 4' is supported by the 2nd holder 4b and the holder 4b is made slidable so as to be parted from the drum 2. The 1st holder 4b turns to face the drum 2 when the 2nd holder 4a facing the drum 2 is slid. Since the 1st developing device is made turnable and the 2nd developing device slidable, the supply of the developer by operating the 1st and 2nd developing devices so as to face selectively the photosensitive drum is made possible and the device is made smaller in size.

Title: Dc power source circuit
Inventor: KAGEYAMA KOSHIN
IPC: G05F1/56
Filed: 1990-09-26
Abstract: PURPOSE:To eliminate a voltage characteristic fluctuation caused by a temperature rise to supply a stable voltage even if the voltage of an output voltage control part is varied by providing an output voltage stabilizing part for keeping a control current supplied to the output voltage control part constant. CONSTITUTION:When a power source turn-on signal arrives at a power source turn-on/turn-off part 24, a transistor T1 is turned on. As a result, a transistor T4 and a Zener diode Z3 are also turned on. Simultaneously, a transistor T3 and Zener diodes Z1, Z2 are turned on, and a output voltage of a power source circuit is outputted. Subsequently, when an output voltage variable signal arrives, the Zener Diode Z2 is turned off, and the output voltage of the power source circuit becomes VZ1-VBE3. In such a state, when VZ2 becomes about '0', since a voltage applied to a current limit resistance R1 is VZ3-VBE4 and con stant, power consumption in an output voltage control part 21 does not increase either and a stable output voltage can be obtained.

Title: Paste applying machine
Inventor: ISHIDA SHIGERU
IPC: B05C5/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to control and remove the sagging amt. of paste at the front end of a nozzle even in a standby state. SOLUTION: This paste applying machine is so constituted that the front end of the nozzle disposed at a syringe 13 is photographed by an image recognition camera 16c. The sagging amt. of the paste at the front end of the nozzle is determined from the photographed image of the image recognition camera 16c by using an image processor to be used only at the time of the image positioning of a substrate. The vacuum degree to act a negative pressure on the inside of the syringe 13 and the impression time are determined from the result of the measurement and, thereafter, the negative pressure is acted in the syringe 13 to retract the liquid sagging from the front end of the nozzle. The sagging amt. of the paste at the front end of the nozzle is then feedback controlled.  If the sagging amt. of the paste is large, a dummy coating application part 22 disposed at a substrate table is depicted with the paste sagging from the front end of the nozzle, by which the paste is removed. As a result, the sag state of the paste at the front end of the nozzle is maintained.

Such ultramicro particle-like beta type silicon carbide is obtained from organic silicon carbide in which at least one identicalsSiH bond exists in one molecule but no SiX (X is halogen atoms or oxygen atom) bond exists, such as a methyl hydrogen silane compound, which is subjected to a vapor phase cracking process at a temperature of about 750 deg. C, and is then heat-treated at the temperature of 1,000 to 2,000 deg. C. Thus, it is possible to rapidly obtain an excellent polished surface with no scratches.

Title: Lower tie plate of fuel assembly
Inventor: SHIRAKAWA TAKEETSU
IPC: G21C3/33
Filed: 1990-09-28
Abstract: PURPOSE:To enhance the cooling efficiency of fuel rods to heighten the boiling transition output of a nuclear reactor by arranging the second ribs from the outer frame of a lower tie plate to the outer frame, making the outermost rib thicker than the other and placing the central ribs to much more near the center part. CONSTITUTION:In regard to ribs 30 connecting a lower tie plate 23 to an outer frame, ribs 30a connecting the second bosses 29a from the outside are arranged at the position to the boss center and ribs 30b connecting a first bosses 29b to the second bosses 29a coupled to the outer frame of a tie plate are connected to a thicker one compared with the inside ribs 30c. Further ribs 30d connecting four bosses 29 arranged in the center part of a tie plate are coupled at the position to the center. Thereby coolant allowed to flow along the inner wall of a channel is restricted because a coolant pass area near the wall face of the channel is narrowed, and a coolant flow is increased because the coolant area is increased to flow in fuel rod groups and a coolant flow quantity is increased so the cooling efficiency of the fuel rods can be improved.

Title: Production of flame-retardant resin composition
Inventor: NAKAMURA KEIKO
IPC: C08L23/08
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To provide the production process for flame retardant resin composition which has excellent resistance to bleeding, particularly suitable for insulating coating layer for electric wire and for the sheath layer. SOLUTION: This flame-retardant resin composition is prepared by kneading a non-halogen olefinic polymer and antimony trioxide to form their mixture, then kneading the mixture with a chlorinated polyethylene. In the composition prepared according to this process, a large amount of antimony trioxide is admixed to a non-halogen olefin polymer such as an ethylene-vinyl acetate copolymer, while a reduced amount of antimony trioxide is admixed to a chlorinated polyethylene. Thus, the reaction of the chlorinated polyethylene with antimony trioxide is inhibited to improve its bleeding resistance and the flame retardancy can be maintained for a long period of time.
