Filed: 1993-07-08
Abstract: PURPOSE:To obtain an optical scanner capable of recording image information with plural kinds of resolution by making the pitch (scanning interval) of a light beam in a direction orthogonally crossing a scanning direction variable. CONSTITUTION:After plural light beams radiated from a light source means 1 provided with plural light emitting parts are conducted to a deflecting means 4 through an optical means and deflected and reflected by the deflecting means, they are conducted to a surface to be scanned 6 through an image forming means 5 so that the surface to be scanned is simultaneously optically scanned with plural light beams. In such a case, assuming that an angle formed by crossing a line linking image forming positions on the surface to be scanned with plural light beams and a scanning line in the scanning direction on the surface to be scanned is theta, the angle theta is made variable by an angle adjusting means.

Title: Inter-multiplace video conference system
Inventor: HIMORI TAKESHI
IPC: H04M11/00
Filed: 1991-08-01
Abstract: PURPOSE:To smooth the progress of a conference by displaying the calling of a certain attendant at the conference or the will of an attendant on a specific position of a monitor screen by individual color and code. CONSTITUTION:When a prescribed button in an operation button device 13 is depressed in the case of displaying the will of a certain attendant, the information is edited and synthesized to a screen format by a calling device through a multi-place video conference device 10, and then the synthesized information is sent to video conference terminals A to N. In the case of starting a conference, a calling device 20 writes a place name on a status display screen based on calling signal information outputted from the device 10 and displays a place displaying telop on the monitor screens of all attendants. When response information is inputted from a certain attendant, the device 20 substitutes a prescribed color for the place name telop displayed on the status display screen. Thus the progress of the multi-place video conference can be smoothly executed by displaying additional information required for the conference progress.

Title: Sewing machine
Inventor: TAJIMA IKUO
IPC: D05B51/00
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To manage the number of times of thread breakage for the small number of sewing machines without the need of performing centralized management and to facilitate maintenance or the like while suppressing a cost to be low. SOLUTION: When a thread breakage detection timing comes, a sewing machine controller 100 outputs operation signals to thread breakage detectors 10A, 20A,..., Z0A. The thread breakage detectors 10A or the like receive pin signals outputted from sewing machine heads 10, 20,..., Z0 and output detection signals including the presence/absence of thread breakage generation. The sewing machine controller 100 receives the detection signals outputted from the thread breakage detectors 10A or the like, and in the case of the thread breakage generation, counts the number of times of the thread breakage for each needle bar (or for each sewing machine head 10 or the like) and displays it at a display device 116.  In such a manner, the number of times of the thread breakage is managed for the small number of these sewing machines without the need of performing the centralized management and the cost is suppressed to be low. Since the number of times of the thread breakage is displayed at the display device 116, the maintenance or the like is easily performed.

Title: Laser diode module
Inventor: MAEDA HIDENARI
IPC: H04B10/07
Filed: 1987-08-04
Abstract: PURPOSE:To monitor oscillation light without causing the loss nor deterioration of signal light by extracting polarized light which crosses the axis of polarization of the signal light from a light beam in a laser diode module directly as monitor light and inputting the monitor light to a photodetecting element. CONSTITUTION:Two linear polarized light beams from a laser diode 1 are incident on an analyzer 4 after passing through an optical isolator. The analyzer 4 is a polarized light separating element made of, for example, calcite, so a light beam projected from the optical isolator like a Faraday rotator 5 can be separated into complete ordinary light as 1st linear polarized light and complete extraordinary light as 2nd linear polarized light. Then the 1st linear polarized light projected as the ordinary light is used as the signal light and the 2nd linear polarized light projected as the extraordinary light are used as the monitor light. Consequently, the need to connect a monitor branching element, etc., is eliminated and the loss and deterioration of the send signal light are eliminated.

Title: Rotary compressor
Inventor: SATO JUN
IPC: F04C29/00
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To improve the abrasion resistance of a vane by installing a nitriding layer of specified Vickers hardness(HV) on a surface of this vane, and applying an ion plating process on the top. SOLUTION: A vane is provided with a nitriding layer 11 with Vickers hardness of more than 1050Hv in advance and, after being further applied with an ion bombardment process on the top face, it is also provided with a coated layer 9 made up of an ion plating process. At a time when this ion bombardment process is applied, a temperature of the nitriding layer is controlled so as not to make the vane's temperature become more than the nitriding temperature, thus preventing the nitriding layer from turning to porousness. In this connection, there is a correlation between the hardness of this vane's nitriding layer and an abrasion loss, namely, if hardness of the nitriding layer is lowered, the abrasive loss grows larger.

Title: Image pickup tube
Inventor: OKU KENTARO
IPC: H01J29/48
Filed: 1984-09-19
Abstract: PURPOSE:To reduce the contrast in the return beam image by installing an auxiliary electrode in addition to a deflecting electrode in the vacuum case of an electromagnetic-focusing electrostatic-deflection-type image pickup tube and producing an adequate potential difference between the auxiliary electrode and a cylindrical electrode. CONSTITUTION:An auxiliary cylindrical electrode 7-1 is installed between a cylindrical electrode 601 and a deflecting electrode 108. Although the orbit of a traveling beam 301 is similar to that in a conventional image pickup tube, the beam passing near the cylindrical electrode 601 is greatly deflected by an intense electric field produced between the cylindrical electrode 601 and the auxiliary cylindrical electrode 701. As the result, a reflected beam 303 is caught by a disk-like electrode 5 having a square window-like opening and can not reach a target 107. Consequently, it is possible to reduce the contrast in the return beam image.
