Title: Driving force controller
Inventor: SUGIHARA KOICHI
IPC: B60W10/10
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To eliminate use of an actuator for releasing a torque transmission clutch for minimum number of parts by fitting a torque transmission clutch engaging mechanism which always engages the torque transmission clutch during the operation of a driving force source. SOLUTION: In an automatic frictional clutch 9, a piston 19 is pressed to pressure receiving plate 18 side by the elastic force of a compressive spring 23, and pressure oil is supplied to a hydraulic chamber 22 through oil passages 33, 32, 12. A reversing driven gear and a counter shaft are released. Therefore, the torque onto an engine is transmitted to an input shaft 7 through the automatic frictional clutch 9. The rotational speed onto the engine and the rotational speed of the input shaft 7 are almost kept constant, however, no torque is transmitted to the counter shaft, therefore, a vehicle is maintained in a stop state.

Title: Image forming device
Inventor: KURIHARA KATSUMI
IPC: G03G21/00
Filed: 1990-09-25
Abstract: PURPOSE:To prevent the occurrence of the meandering and biasing of a dielectric belt by setting the width of the dielectric belt of a transfer means larger than that of a bias roller facing an image information carrier with the dielectric belt interposed. CONSTITUTION:The transfer belt 11 composed of a dielectric is stretched between a transfer bias roller 27 and a driving roller 9. The transfer belt 11 is formed with an elastic belt, and its width is larger than that of the transfer bias roller 27. In other words, when the width of the dielectric belt 11 is defined as L, the width of the bias roller 27 is defined as M, and the width of the image information carrier is defined as N, the relation of these widths is L>M>N. Both end parts of the transfer belt 11 are turned and inserted into both end parts of the transfer bias roller 27 to be stretched. On the other hand, the surface of one end part of the roller 27 or the surfaces of its both end parts are insulated.

Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain an optical fiber diffraction grating clad which is intensified in the sensitivity of material for the purpose of a reconstitution characteristic by arranging plural heating elements, generating a temperature gradient along the length of diffraction gratings, and chirping the diffraction gratings. SOLUTION: The device 9 has an optical fiber 11 of a certain length having a series of the optical diffraction gratings 12 having refractive index perturbation 13 and plural heating elements 10 along the diffraction gratings 12. The optical fiber 11 usually has a central core 14, an external cladding 15 and an external coating 16 of the temperature sensing material. The heating elements 10 are made of resistant metals for correcting the diffraction gratings 12 by local heating.

This change effectively chirps the diffraction gratings 12.  The heating elements 10 are arranged at uniform intervals and are capable of establishing the desirable gradient by changing the effective heating capacity (for example, the number of coils) thereof.

Title: Method of manufacturing fluorescent lamp
Inventor: URATA YOSHIZO
IPC: C09K11/02
Filed: 1984-12-04
Abstract: PURPOSE:To perfectly prevent a coated film from pealing off due to firing even if suspension unexpectedly stays in the collar portion by employing a binder other than explosive nitrocellulose as the binder of the first light-emitting layer. CONSTITUTION:Suspension is poured into a glass bulb 2 through a nozzle 1. And the second light-emitting layer 4 is formed on the first light-emitting layer 3 by drying up with hot air. Then, the glass tube 2 is placed in a heating furnace of its temperature controlled between 500-600 deg.C, and both light-emitting layers 3 and 4 are fired at the same time. For the fluorescent lamp thus manufactured, neither explosive firing at the firing process even in the case that the first suspension stays at the collar portion 2a located at the lower end of the glass bulb 2 and the film becomes extremely thick while the light-emitting layer is formed, nor damage, pealing off of the light-emitting layers 3a, 4a of the same portion does not take place. The reason is that the binder other than explosive nitrocellulose, that is, polyethylene oxide is employed for the light-emitting layer 3.

Abstract: PURPOSE:To enable waiting time to be shortened for a person to leave an automobile since a door has been opened by enabling a seat belt to be actuated from a fitting condition to a releasing condition when an ignition switch is turned off or even when the door is closed with a key pulled cut. CONSTITUTION:When the occurrence of an ON signal from a door switch 12 and an ON signal from a key pull-out detecting switch 9 is taken as an OR condition, if the ON signal is issued from one of the switches, that is, when the door 11 is opened, or when a key is pulled out from an ignition switch 8, a motor 5a is made to start rotating normally.

Title: Disc-shaped recording carrier reader
Inventor: HIRUDE MARIA ARUDA OBERATO
IPC: G11B7/08
Filed: 1985-11-19
Abstract: The apparatus ensures that locking-in to the track (25) of a record carrier (1), for example a compact disc, is effected at the most eccentric point (28) of a circle (27) described by the light spot P, which is projected on the record carrier by a light beam via an objective system (8), when the record carrier rotates and the objective system is stationary. In this point the relative radial speed of the light spot P with respect to the track is minimal, so that locking-in can be effected in the simplest way at this instant. 
<??>The radial positioning means (77) are switched on at this instant under the influence of a first control signal (S1), which is applied to a lock-in system (78). 
<??>Moreover, locking-in to the track at this most eccentric point (28) has the advantage that even if the objective system is in its initial position, which means substantially against the stop it remains possible to follow the track even atter the first complete revolution of the record carrier after locking-in so that no loss of track occurs. This would be possible in the case of locking-in to the track of an eccentric record carrier at a point other than the above-mentioned point.
