Title: Evaporation fuel processor
Inventor: ISOBE TAKASHI
IPC: F02M33/00
Filed: 1999-11-02
Abstract: PROBLEM TO BE SOLVED: To prevent the negative pressure state of a tank system from being determined in error to be the state, where there is no leakage in the tank system by determining non-leakage, when an internal pressure indicates negative pressure and it is not in high load operating conditions. SOLUTION: It is determined whether the current atmospheric pressure is larger than the atmospheric pressure, at starting of an engine by a designated value of larger (401). If this is 'NO', it is determined whether the value (load of an engine) obtained by multiplying the fuel injection amount per unit time by the rotating speed of the engine is a designated value or larger (402). If the load is not larger than a predetermined value, a predetermined time is set on a high load operation determining timer (404), 0.5 mm OK determination inhibit flag (0.5 mm, not suitable for reference determination) is erected (405), and when the release timer (designated time is set when it is not suitable for determination of presence/absence of leakage of 0.5 mm reference) is zero (406), an OK determination inhibit flag is set to zero, to release determination inhibition (407).  The presence/absence of leakage with 1 mm, 0.5 mm reference is detected.

Title: Optical information storage
Inventor: MORIMOTO YASUAKI
IPC: G11B7/1359
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To detect the tilt quantity of a recording medium by detecting luminous flux transmitting a beam splitter among luminous fluxes which transmitting the first surface of the beam splitter and reflecting on the second surface of it and irradiating and reflecting the recording surface of the recording medium. SOLUTION: A polarizing film and a reflection film 3 are respectively provided on the first surface and the second surface 2b of a plate like beam splitter 2. The main beam 30 reflecting on the first surface 2a and the reflecting subbeam 31 reflecting on the second surface 2b pass different paths. As a result, both beams reflecting on the recording surface of a disk 10 form images at different positions. A photodetector 13 (bisected photodetectors) is arranged at a position where the image formation of the reflecting subbeam 31 can be received. When there is the inclination of α degrees in the disk 10, the image formation of the reflecting subbeam 31 being on the photodetector 13 is offset to a Y direction. Thus, the tilt quantity of the recording medium (disk 10) can be obtained from the difference between outputs of two detecting parts of the photodetector 13.

Title: Acoustic conductor and manufacture thereof
Inventor: AKUTA YASUO
IPC: C22C9/00
Filed: 1989-12-01
Abstract: PURPOSE:To reproduce a good quality of sound from a high frequency range to a low frequency range by a method wherein the inside of a copper conductor excluding the neighborhood of its surface is made up of an annealing structure, a solidification structure or a unidirectional solidification structure of single crystal and the neighborhood of the surface of each of them is made into a work structure. CONSTITUTION:The quality of sound in a high frequency range is influenced by a current flowing in the external circumferential portion of a conductor, and the quality of sound in a low frequency range is influenced by a current flowing in the central portion of the conductor. The single crystal annealing material or ingot of copper or the unidirectional solidification ingot of copper is therefore drawn through a die to make the neighborhood of the surface thereof into a work structure and its working ratio is determined at 4-20% in terms of reduction of area. If the working ratio is less than 4%, the region to be a working structure is thin so that the quality of sound in a high frequency range cannot be improved, and if the working ratio exceeds 20%, the working structure reaches the inside of the conductor so that the quality of the low frequency range deteriorates. It is thereby possible to satisfactorily reproduce the quality of sound of an acoustic equipment from a high frequency range to a low frequency range.

Title: Picture device
Inventor: MURANO SHUNJI
IPC: H04N1/036
Filed: 1993-12-14
Abstract: PURPOSE:To form the latent images of high picture quality in a photosensitive body by attaching a board plate on the lower surface of a printed board. CONSTITUTION:The lens plate 6 of a lens member 5 is abutted and fixed on the reference surface 8a of a supporting body 8 and the printed board 2 of a picture element member 1 is abutted and fixed on the reference surface 8b. Thus, light emitting diode element arrays 3 and lenses 7 are in one-to-one correspondence with the gap of a prescribed distance. Since a highly rigid metallic plate 4 is mounted to the lower surface of the board 2 of the member 1, even when external force is applied to the member 1, deformation such as a warp and a twist, etc., is not generated in the board 2. As the result, the arrays 3 mounted to the board 2 can be accurately placed opposite to the respective lenses 7 at all times. Thus, the entire surface of the photosensitive body is well irradiated with light emitted by the light emitting diode elements 3a of the respective arrays 3 and the accurate latent images can be formed in the photosensitive body.

IPC: G03G15/20
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To always correctly detect the surface temp. of a moving body to be measured with a simple constitution, while reducing the cost, by providing a temp.-sensitive element across an elastic pressing member on a supporting body on the rear side of an endless belt corresponding to a measuring region of the moving body to be measured. SOLUTION: Since the temp.-sensitive element 50 is pressed to a heating roll 11 by a buffer member 44 across the endless belt 42, heat from the heating roll 11 is immediately transmitted across the endless belt 42, and the temp. of the heating roll 11 is detected. In this temp. detecting work process, the endless belt 42 is held between the shaft 41 and the heating roll 11, therefore it is driven-rotated following rotation of the heating roll 11. Thus, even if a little toner on a paper sheet 13 is offset on the heating roll 11, the little toner is always allowed to pass through a nip part A between the endless belt 42 and the heating roll 11, inversely shifted to a next feed in paper sheet 13 side, and thus removed.

Abstract: PROBLEM TO BE SOLVED: To realize high speed exposure time and to eliminate the useless movement of a motor being a driving source by charging a 2nd light shielding member with a 2nd charge mechanism after completing the charge operation of a 1st light shielding member with a 1st charge mechanism. SOLUTION: A charge gear for a closing blade 29 and a charge plate for a closing blade 26 (1st charge mechanism) restore an opening blade, which is displaced from a closing position where an exposure aperture part is closed to an opening position where it is opened in the case of exposure operation, to the closing position. A charge gear for an opening blade 25B and a charge plate for an opening blade 27 (2nd charge mechanism) restore a closing blade, which is displaced from the opening position where the exposure aperture part is opened to the closing position where it is closed, to the closing position. Then, the charge operation by the 2nd charge mechanism is performed after completing the charge operation by the 1st charge mechanism. Namely, the 1st charge mechanism is driven when the motor 12 is normally rotated, and the 2nd charge mechanism is driven when the motor 12 is reversely rotated. Therefore, load is not imposed on the motor 12, and the motor 12 is prevented from being uselessly rotated.
