Title: Radiation beam gathering device for synchrotron orbital radiation
Inventor: ENDO MASAHIRO
IPC: H05H13/04
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To make fine adjustment of the vertically directed refraction of the radiated light precisely and easily and prevent a long stretching mirror from breakage by coupling a step motor through a torsion bar with the shaft of a fixing member on the same axis. SOLUTION: When a geared step motor 15 is operated, its torque is transmitted to the shaft 7 of each fixing frame 3 through a torsion bar 19. Because the torque is buffered by the resiliece of the torsion bar 19, no unreasonable load of bending moment will act on a long stretching mirror 1 even though the two fixing members 3, 3 rotate round the axis of the shaft 7 which is borne by an outer frame 8 through bearings 10. The refraction of the vertical component of the radiated light can be fine adjusted easily by performing feedback control through utilization of the curvature characteristic value in longitudinal direction of the mirror 1, and thus the mirror 1 can be precluded from breakage.

Title: Optical scanner
Inventor: TAKI KAZUYA
IPC: G02B26/10
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To provide an optical scanner capable of using an inexpensive hologram. SOLUTION: The major axis of an outgoing laser beam 31 from a semiconductor laser 10 is in parallel with a main scanning direction, and the polarizing direction of the beam 31 is in parallel with a sub-scanning direction. The length of a parallel light beam 33 in the main scanning direction becomes shorter as the focal distance of a collimator lens 11 becomes shorter, and vignetting by the lens 11 becomes smaller. Since the beam diameter of the beam 33 both in the main scanning direction and in the sub-scanning direction is the same as or smaller than the width of a slit 12, light quantity loss is small, and the efficiency of utilization becomes high. Thus, the diffraction efficiency of a hologram disk 16 can be made low, so that the hologram can be inexpensively manufactured.

Title: Method for revising communication address for on-vehicle electronic device
Inventor: SANO TADASHI
IPC: G11B19/02
Filed: 1994-09-26
Abstract: PURPOSE: To allow the user to listen to an audio program while observing an image by employing a reproducing device able to reproduce a CD-ROM for one of two reproducing devices so as to configure a network. CONSTITUTION: CD changers CHG1, CHG2 are both set to the audio mode, a switch 31 of an extension box 30 selects the changer CHG1 and a loaded CD is being played. When an ACC switch of a vehicle is closed, the switch 31 is closed, the changer CHG1 checks a CD in a CD magazine to confirm what disk number corresponds to a CD-ROM. However, since the mode has been set to the audio mode, an address A is not revised and the same mode is set. In this state, a large pattern of a CD selected by the CD changer CHG1 is read and outputted for display, the CD changer CHG2 is set to the audio mode, then an audio CD is read and a signal is outputted, thus the audio CD is listened to while observing a pattern of a navigation map or the like.

Title: Semiconductor light emitting device
Inventor: OMURA TAKAHIRO
IPC: H01L33/22
Filed: 1986-10-27
Abstract: PURPOSE:To obtain an EELED where oscillations are not generated at a low temperature region by regulating an area applied by an electric current to the total area of an active layer; besides, by preparing nonreflective films at both end planes of a light emitting face and a rear end face. CONSTITUTION:An electrode contact layer 13 and an electrode 14 are formed at a part adjacent to a light emitting part so that areas occupied by them may be less than 30% of the total area of an active layer 12; besides, both end planes of a light emitting face and a rear end face are coated with nonreflective films 16 and 17. Then an electric current is applied from the electrode 14 only to a part of the active layer 12 that is adjacent to the electrode but the part of the active layer 12' that is lacking in the electrode 14 functions to absorb or scatter lights. Its function makes a photon density in a waveguide (a part adjacent to the waveguide inclusive of the active layer) smaller and as an area applied by the electric current is restricted, the electric current density in the active layer becomes higher. The its non-radiative recombination of an Auger effect and the like increases and oscillations are hindered. This approach contributes to suppressing the oscillations in a low temperature region.

Title: Method for forming neck part of metallic thin container and its holder
Inventor: YOSHIDA TOSHIO
IPC: B21D51/26
Filed: 1994-10-21
Abstract: PURPOSE: To form a can neck part without buckling and breaking its body part at a size within tolerance by inserting an elastic core into the can, pressing this core and pressing the can neck part from outside by a forming roll device while rotating the core in tight contact with the can. CONSTITUTION: The can 3 to be formed with the neck part 4 is inserted into a holder 5 and the elastic core 1 is loosely inserted into the can 3. A pressing plate 6 is fitted to the top end of the elastic core 1. This pressing plate 6 is supported by a rotatable pressing rod 7. Pressing force is applied on the pressing rod 7 and is transmitted via the pressing plate 6 to the elastic core 1 at the time of a static state when the holder 5 does not rotate. Consequently, the elastic core 1 inflates in an outside diametral direction and eventually comes into tight contact with the inside wall of the can 3 and fixes the can 3. Next, the can is rotated integrally by the friction force of the bottom of the can 3 with the inside wall of the body when the holder 5 is rotated at an adequate speed by a rotating device.  The roll device 8 is directed toward the neck part 4 of the can 3 and is rotated simultaneously in directions X, Y and XY while the pressing force to overcome the inflating force is applied thereon.

Abstract: PURPOSE:To achieve a uniform through hole depth and prevent step disconnection of a 2nd layer interconnection during the formation of deep through holes by forming a sacrifice film used for etchback planarization of an interlayer insulation film in the same region and to the same height as the step difference formed prior to the formation of a 1st layer interconnection. CONSTITUTION:A 1st sacrifice film 7 and a 2nd sacrifice film 8 are formed on an interlayer insulation film 6. When the respective etching selectivity rates of the sacrifice films 7 and 8 compared to the interlayer insulation film 6 are the same. the film thickness of the sacrifice layer 8 is formed to be equivalent to the height of the step difference formed by the separation oxide film 2 prior to the formation of the 1st layer interconnection 4.

After this, total surface etching is performed under conditions that make the etching rates of the sacrifice films 7 and 8 and the interlayer insulation film 6 equivalent. As a result of this etching, the interlayer insulation film 6 is higher in regions above the separation oxide film 2 and lower in other regions, but the film thickness of the insulation film 6 is the same as the 1st layer interconnection 4 both above the separation oxide film 2 and in other regions.
