Title: Spectroscope
Inventor: KITA TOSHIAKI
IPC: G01J3/30
Filed: 1994-05-30
Abstract: PURPOSE:To observe an emission spectrum of a light source by arranging a view port to peep a concave diffraction grating to separate light passing through a slit-like window into its spectral components, an irregularly reflecting surface of diffracted light and an irregularly reflecting surface, and peeping toward the light source. CONSTITUTION:A spectroscope 1 is formed as a rectangular structure of the palm size, and a window 6 of a slit 5 is arranged in a wall surface 2, and a view port is arranged in a wall surface 4. The inside of the wall surface 2 is painted in white, and a concave diffraction grating 7 is installed in the corner with the wall surface 4 on a wall surface 3. When the slit side of the spectroscope 1 is turned toward a light source 9, a part of emitted light 10 of the light source 9 is made incident on the concave diffraction grating 7 through the slit, and is separated into its spectral components. Spectral light reaches the wall surface 2, and a spectral spectrum image 8 is formed. Since an inside surface of the wall surface 2 is painted in white, the light causes irregular reflection, and the spectral spectrum image 8 can be visually observed by peeping from the window 6, and an emission spectrum of the light source 9 can be observed. In this way, the distribution of the emission spectrum of the illuminating light source can be simply observed by peeping the spectroscope 1 while turning it toward the light source.

Title: Decision system for carrier regenerative lead-in phase
Inventor: KAKUBARI MINORU
IPC: H04L27/38
Filed: 1977-09-29
Abstract: PURPOSE: TO discriminate whether or not a regenerative carrier lead-in phase has been led into an odd vector position through the exclusive-OR between demodulated signals, after discriminated by two threshold levels, of intersecting partial response modulation signals of the lst kind.  
     CONSTITUTION: Carriers from carrier regenerative circuit CRR are applied to phase detectors PD1 and PD2. Here, modulated signals IN are phase-detected and applied to discrimination circuits ID1, ID2 and ID3 via absolute-value circuits AR1 and AR2. In ID 1  and ID 2 , they are discriminated by threshold level V 1  equal in level, and demodulated outputs can be obtained from CH1 and CH2. In ID3, the discrimination is done by threshold level V 2  greater than V 1 . Then, the output of exclusive- OR circuit EXOR becomes "0" when regenerated carriers are being led into the odd vector position. On the other hand, when they are being led into the even vector position, its output appears, which is integrated by integrating circuit ITG and then applied to regenerative circuit CRR, thereby attaining the re-lead-in operaton

Abstract: PURPOSE: To provide a rotary connector having the high density of contact points for a detachable circuit board by spirally winding a conductive wire around a bobbin, cutting the wire at least at one position for forming an end part, securing the wire with a retainer and then rotating the bobbin. CONSTITUTION: A system 10 has a circuit connector 12 to connect a conductive pad 14 on a back plate circuit board 16 to a detachable circuit board 22. The pad 14 has contact point rows 24 and 26, and the detachable circuit board 22 has contact point rows 32 and 30 corresponding thereto. Also, a connector 12 is formed so that a conductive wire 56 is spirally wound around a slender bobbin at a gap, and a part of the wire 56 for forming a contact point is kept away from the bobbin via a spacer bar inserted. Then, the part is separated to form a contact point. The separated wire is attached to the bobbin with a retainer, and the end of the wire is used to form a contact point 105. At the same time, the end of the wire is formed to have the capability of being internally dislocated via resiliency. According to this construction, many contact points concurrently pressed to the surface of the circuit board 16 can be formed by rotating the connector 12.

Title: Recorder
Inventor: OGATA NOBUAKI
IPC: H04N1/00
Filed: 1982-07-06
Abstract: PURPOSE:To obtain high-quality recording information without crimped portion by easing abrupt variations in loads by forming a high-frictional face on the inner side of the flange of a spool. CONSTITUTION:After recording by an electrostatic recording head, a recording paper 2 is sent out forwards by a necessary length and cut off by a cutter 4. A head-pressing roller 3 is reversely turned to draw back the recording paper 2, and slackening is brought about by a flange 8. Since a high-frictional material, e.g., rubber part, etc., is bonded on the inside of the flange 8 of the spool 5, when the recording paper 2 is sent out forwards as the next recording is started, the spool 5 begines to turn by the frictional force between the recording paper 2 and the high-friction material and the feeding load of the recording paper is thus lessened.

Title: Point-to-multipoint atm connection setting method
Inventor: KODAMA TOMOAKI
IPC: H04L12/28
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To consider sharable connection that is already set and to effectively perform the utilization, etc., of a transmission line by selecting one physical transmission path in accordance with set situation of the existing point-to- multipoint ATM connection where the same cell as an additional connection is caused to flow for adding the connection. SOLUTION: The physical transmission line of 'a node A → a node B →a node C' is selected because the weighting value of each physical transmission line is 'w=3', for instance, in the case of setting ATM connection arriving from a node A to a node C. After the connection setting is completed, the weighting value of 'w'=1' is newly defined for weighting of transmission lines 'between the node A → the node B' and 'between the node B → the node C' which are the physical transmission line that is selected as a path. After that, in the case of setting additional ATM connection arriving from the node A to a node D, a path 'the node A → the node B →the node C → a node D' is adopted from the sum total comparison of a transmission path weighting values of the transmission lines.

Title: Floating magnetic head
Inventor: OKUYAMA SHINICHI
IPC: G11B5/60
Filed: 1991-05-22
Abstract: PURPOSE:To provide a good electromagnetic conversion characteristic and mechanical reliability for a floating magnetic head. CONSTITUTION:In the floating magnetic head in which a wire connecting a magnetic core with the electric circuit of a drive device body is inserted into an insulating tube and fixed to a load beam, a small lump is stuck to one end part of the wire on the magnetic core side of the insulating tube. Even if the wire is pulled from the body side of the drive device, the small lump stuck to the wire is caught at the entrance where the wire is inserted to the insulating tube. Accordingly, unless the insulating tube, which is fixed to the load beam and a mount, is moved, the wire is not moved either. Thus, the shape of a wire loop is retained, and the freely floating posture of a slider at the time of using the floating magnetic head is not restricted by the slack of the wire loop.
