Title: Magnetic steel sheet having high machinability and magnetic characteristic
Inventor: MAEDA MITSUYO
IPC: C22C38/00
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic steel sheet having high machinability and a high magnetic characteristic by specifying the number of inclusions having a specific particle size or larger of the inclusions observed on the end face of steel sheet against the total number of inclusions. SOLUTION: Test pieces of a nonoriented magnetic steel sheet which contain nearly the same number (about 8,000-10,000 particles/mm2) of inclusions having particle size of >=0.1 μm, about 1 wt.% (Si+Al), about 110-130 Vickers hardness, and inclusions in various particle size distributions are examined and the test pieces are put in order based on the ratio (%) of the number per unit area of inclusions having particle sizes of >=0.1 μm to the number per unit area of inclusions having particle sizes of >=2 μm. When the number of the inclusions having particle sizes of >=2 μm exceeds the 10% of the total number of the inclusions having particle sizes of >=0.1 μm, the machinability of the magnetic steel sheet is improved. In addition, the kinds of the inclusions have no relation to the magnetic characteristic and machinability of the steel sheet.

Title: Operating method for optical transmission system and interference discrimination system
Inventor: ROBERT KIM BYRON
IPC: H04B10/00
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To measure accurately multi-path interference (MPI) amount by using an element for an optical transmission system, measuring a light sent in a downstream direction at a downstream position of a light source and analyzing a frequency modulation product in the measured light. SOLUTION: An optical signal passes an optical path including an optical element 1 having a reflectance R1, an optical element 2 having a gain G1, and an optical element 3 having a reflectance R2. The 1st reflection and the 2nd reflection from the reflecting element in the optical path are shown in figure roughly. As a result, a signal reaching an MPI parameter measurement section 4 provided to the downstream of reflection includes a desired signal and an interference component resulting from two reflection events. The measurement section 4 detects part (e.g. 5%), samples the signal at, e.g. 10MHz to calculate the intensity of the MPI and the operation delay.  The identification characteristic of the MPI in a frequency spectrum is precisely extracted by a minimum calculation by including the analysis of the frequency spectrum pattern resulting from the comparison with a prescribed frequency spectrum for the analysis of the frequency modulation product.

Title: Video conference terminal and multispot video conference method
Inventor: MAEHARA NORIAKI
IPC: H04M11/00
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To improve the secrecy of a conference by refusing unwanted connection of video conference terminal by performing communication regardless of the conference under holding, by enabling the temporary connection of any other new video conference terminal during a multispot video conference. SOLUTION: When the terminals cell of the new video conference terminal is reported to a main control means, a multispot conference control means stops transmission to video conference terminals 35 and 36 under connecting. The execution of the video conference in apparent one-to-one corresponding with a video conference terminal appears to be for a video conference terminal 37, when the video conference terminal 37 is temporarily connected. When an input from a remote controller is accepted and 'addition to multispot conference' is selected, after the communication with the video conference terminal 37 of a temporary connected party has started, the main control means reports that information to the multispot conference control means and executes the multispot video conference due to all the connected video conference terminals 35-37.  It can be discriminated by the temporary connection, whether or not the terminal can participate in the multispot video conference through that connection.

Title: Air-conditioner for automobile
Inventor: AKASHIBA MASAHIKO
IPC: B60H1/00
Filed: 1989-07-31
Abstract: PURPOSE:To eliminate re-setting of a switch concomitant with the riding on/off of a passenger and to improve comfortableness for an automobile furnished with an automatic air-conditioner, by connecting the switch that detects riding on/off of a passenger through opening/closing of a door to a setting mechanism of the air-conditioner through a timer. CONSTITUTION:When the opening of a door concomitant with riding on/off of a passenger is detected by a door switch 11, a timer 10 is actuated, and it is input to a temperature setting means 9, which then judges a state of front and rear seat and changes a setting condition of a corresponding air-conditioner 8. When a predetermined period of time of the timer 10 elapses the setting condition of the air-conditioner 8 is restored to the original state by the temperature setting means 9. Change of setting concomitant with riding on/off of a passenger becomes thus unnecessary, and comfortableness can be maintained.
