Title: Combustion device
Inventor: HIRATA YASUSHI
IPC: F23D14/14
Filed: 1985-05-02
Abstract: PURPOSE:To prevent the phenomenon of lifting, the deformation of metallic net as well as its breakage for a period ranging from a high combustion to a low combustion and enable a wide range of adjustment of combustion by a method wherein a net having biased flame holes therein is closely attached to a cylindrical burner head having a plurality of slit-like flame holes at its side surface which is elongated in its vertical directions and of which width is less than a specified value (3mm). CONSTITUTION:Since a flame A during a high combustion is formed relatively distant from the surface of a metallic net 6 having several flame holes therein, the metallic net 6 is hardly red heated. In turn, during a low combustion since an injecting speed of premixture gas is delayed, both flame A and auxiliary flame B are ignited at the surface of the metallic net 6. Owing to this fact, although a lifting phenomenon is not generated, temperatures of the metallic net 6 and the flame holes 5 and the like is liable to increase. In case that the metallic net 6 is closely attached to the burner head 4, the flame holes 5 are of longitudinal slits and their widths are less than 3mm, a heat from the metallic net 6 may easily be transmit ted to the burner head, the heat is hard to be accumulated at the central portions of the flame holes 5, and a cooling action caused by a secondary air between the flame holes 5 causes the temperature of the metallic net 6 to be decreased and then its deformation and breakage can be eliminated.

Title: Laser treating method and system
Inventor: JIYON KEI SHIMITSUKU
IPC: A61F9/007
Filed: 1994-05-09
Abstract: PURPOSE: To accurately correct eye's refraction error. CONSTITUTION: A resection light resolution is conducted by offset image scanning. The images of such changeable aperture as width changeable slit and diameter changeable iris diaphragm are scanned by a pattern determined in advance to carry out the resection at a determined place on the cornea surface. The scanning is conducted by a movable image offset displacement mechanism that can do radial displacements of a profile beam evacuated from the aperture and angled rotation. The profile beam is concerned with the offset displacement mechanism and is rotated by rotating the aperture. As this invention uses a narrower laser to make a treatment in a broader area, it can be used for treating many different cases (for example, hypermetropia, hypermetropic astigmatism, irregular refraction abnormity, smoothing of the resection mark and high beam keratectomy treatment).

Abstract: PURPOSE:To enable taking out of a cassette tape with a stable and smooth operation by using all rigid transmission mechanism to constitute a driving transmission system for taking out a cassette tape from the body of a magnetic recording and reproducing device such as VTR. CONSTITUTION:A driving motor 15 is revolved backward and the revolution thereof is transmitted via a worm 14 to a worm wheel 11 in the case of taking out the cassette tape 1 from the VTR body. The revolution of the wheel 11 in this state is transmitted via a pinion 18 to the 3rd gear 9 and therefore the driving force is rigidly transmitted between the same. The rigid driving transmission system is maintained until the 1st pin 5 passes the curved part of a guide groove 4. The pinion 18 engaged with the 3rd gear 9 is disengaged therefrom when the pin 5 passes the curved part of the groove 4 and thereafter the 2nd pin 18 is driven by the repulsive energy of a pinching spring 13. The taking out operation is thus completed.

Filed: 1995-04-20
Abstract: PURPOSE: To provide a transfer device constituted so that a power source is made compact by using a transfer member whose resistance is lower than that of a conventional transfer member. CONSTITUTION: The transfer device 20 is constituted so that a transfer feasible toner image formed on a photoreceptor (image carrier) 2 is transferred on a transfer material by using a transfer means by imparting electric charge to the back surface of the transfer material. Then, the transfer means is constituted of the plural transfer members 22 arraying in the longitudinal direction of the photoreceptor 2 and provided with a means (pushing-up means) 24 changing the longitudinal-direction width L1 of the transfer member 22 brought into contact with the transfer material or the photoreceptor 2 so as to satisfy the relation of Lp <=L1 <=(4/3)Lp according to the width Lp of the transfer material.  In such a way, when the relation of Lp <=L1 <=(4/3)Lp is satisfied, the sufficient transfer electric charge for preventing the occurrence of a defective transfer action is obtained even in the case that the transfer member 22 whose resistance is low, is used. Thus, the power source and the transfer device 20 can be made compact by drastically lowering a voltage impressed on the transfer member 22.

Title: Manufacture of semiconductor device
Inventor: OBUSE KAZUHIRO
IPC: H01L29/78
Filed: 1987-04-17
Abstract: PURPOSE:To reduce the electric resistance of a gate electrode uniformly, to prevent the growth of a needle-like metal along a crystal grain boundary, and to contrive improvement in the reliability of the title semiconductor device, by a method wherein an amorphous conductive region is selectively formed on a gate and its circumferential surface, and a metallic thin film is formed and alloyed. CONSTITUTION:After a polycrystalline silicon film 130 of about 100 nm has been deposited on a silicon substrate 100, said polycrystalline silicon film 130 is brought into a state of low resistance by diffusing POC 13 thereon. Then, SiF3 is ion-implanted into the polycrystalline silicon film 130, and an amorphous region 140 is formed on the surface. Subsequently, a titanium thin film 150 of about 100 nm is deposited by a physical vapor-deposition method, and an alloy layer 160 is formed by conducting an optical annealing at 1000 deg.C for 10 seconds. At this time, as the mutual bonding energy of the silicon atoms of the amorphous region 140 is smaller than the mutual bonding energy of the atoms of the polycrystalline silicon, the greater part of the material is alloyed in the amorphous region 140. Accordingly, as the thickness of the alloyed layer can be made uniform, the needle-like metal is hardly produced, and the breakdown of a gate oxide film can be prevented.

Title: Polarizing prism
Inventor: SHIRASAKI MASATAKA
IPC: G02B5/04
Filed: 1979-07-27
Abstract: PURPOSE: To perform perfect separation of normal rays and abnormal rays, in the two prisms which comprise uniaxial crystals and of which the planes parallel to optical axis are opposed to each other by way of a micro-space, by paralelling the normal rays and abnormal lays polarized and separated the rays incident by the Brewster angle by the opposite faces to each other and intersecting these orthogonally to light transmission faces.  
     CONSTITUTION: Prisms 10 and 20 are prisms of a triangular column or square column shape comprising TiO 2  and the optical axes thereof are perpendicular to the plane of the figure. A thin air space interposes between their opposite faces C. With respect to the opposite faces C, the face 10A and face 20B are crossing at a Brewster angle θ. When natural light l enters, for example, the face 20A perpendicularly, it is separated to a normal ray lT and an abnormal ray LR on the opposite faces C. The normal ray is perfectly reflected twice within the prism 10 and is emitted in the direction normal to the face 10B. On the other hand, the abnormal ray LR is perfectly reflected twice in the prism 20 and is emitted in the direction parallel to lT and assuming right angle to the face 20B. Thereby, the normal rays and abnormal rays may be separated perfectly and the circulator using these may be made small in size and low in loss.
