Title: Virtual space conference method and record medium recording the method
Inventor: MATSUDA TATSUKI
IPC: H04N7/18
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To allow each participant to grasp a positional relation between with his opposite party to obtain the feeling of having the conferrence in the same space without feeling a physical distance by previously constituting the conference space of participants as a virtual space and constituting the video input of the participants as a CG model so as to compose/arrange the CG model in a virtual space. SOLUTION: A single virtual conference space is constructed in a server in a video conference system connected through a network. The video and sound of all the participants of a video conference in each client 6 are transmitted to the server by a camera 61. The video of each participant is made a CG model to be retained in a form which can be arranged within the virtual conference space. The CG models of the participant video of respective clients are compose-arranged by clarifying their positional relation within the virtual conference space provided for the server. In addition, the photographic condition of each camera 61 is extracted and the moving of the CG model is clarified to clarify an object to talk to to improve presence. A server 5 sends this virtual conference space back to each client 6 to display.

Title: Liquid detector
Inventor: TSUJI HIROYUKI
IPC: G01F23/24
Filed: 1983-05-18
Abstract: PURPOSE:To detect a liquid level independently of operation of an object controller by detecting the difference of air temperature as resistance and voltage changes with a thermo-sensitive device. CONSTITUTION:When the liquid level is secured, that is, when a liquid level detecting self-heating thermo-sensitive device 10 is in the liquid, the output voltage of a liquid temperature detecting thermo-sensitive device 11 (voltage at a point (a)) is higher than the voltage at a point (b) because the output voltage of a temperature compensating operation circuit 12 (voltage at the point (b)) is used as a reference voltage. If the liquid level is lowered, the resistance of said thermo-sensitive device 10 is reduced suddently, and the voltage at the point (a) is reduced in accordance with this reduction. However, the output voltage of the circuit 12 is hardly changed because the thermo-sensitive device of the circuit 12 detects only the ambient temperature, and the voltage at the point (b) is stabilized, and therefore, the voltage at the point (a) becomes lower than that at the point (b), and the output of a comparator 13 is inverted, thereby detecting lowering of the liquid level.

Title: Manufacture of complementary dielectric isolating substrate
Inventor: NEGORO TATSUO
IPC: H01L27/08
Filed: 1982-05-25
Abstract: PURPOSE:To simplify the manufacturing steps of a complementary dielectric isolating substrate and to improve the crystallinity of a substrate by superposing N epitaxial layers on a main surface with the upper and side surface of a trapezoidal island of a P type single crystal Si as masks and providing N type trapezoidal island on the region except the mask. CONSTITUTION:The (100) plane of a P type Si substrate 301 is anisotropically etched through an SiO2 mask 302, the mask 302 is then removed, and an SiO2 layer and an Si3N4 layer are formed as masks 303. The mask on the top of a trapezoidal island is removed, a P<+> type layer 304 is removed, and a thick SiO2 film 305 is covered. When a mask 303 is removed and N epitaxial layers are formed, a single crystal film 306a, a polycrystalline film 306c and a transient region 306b are formed. An insulator isolating substrate is then completed in the same steps as the conventional steps. According to this configuration, the epitaxial steps can be omitted by one, the crystallinity is improved, and one step among photoresist steps for polishing and diffusing impurity can be eliminated, thereby simplifying the manufacturing steps.

Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To decrease the cost of a sensor and to improve the reliability and the durability of the sensor by using the specified metal oxide having low sensitivity for hydrogen as the main component for a gas detecting part. SOLUTION: A gas detecting part 1 is formed on a substrate 1 containing a heater, and electrodes 2 and 3 are provided on the upper part.

Furthermore, the selectivity for the carbon monoxide of the sensor is further improved by providing the catalyst layer of noble metal such as Pt, Pd, Au and the like. Thus, the low-cost sensor having high reliability and high durability can be obtained.

Filed: 1995-04-14
Abstract: PURPOSE: To enlarge inertial mass without decreasing torque characteristic and to improve rotating accuracy by differentiating the outer diameter of each part of the outer surface part of a rotor yoke in correspondence with the thickness of a plastic magnet. CONSTITUTION: With respect to the formation of the thickness of the plastic magnet of an FG magnet 7, the thickness of a driving transfer gear 7a is thick and the thickness of an FG magnet part 7b is thin. Furthermore, the outer diameter of a part of the outer surface part of a rotor yoke 6 corresponding to the FG magnet part 7b is formed largely as a flange 6a. The outer diameter of the part corresponding to the driving transfer gear part 7a is formed smaller. The speed is detected with a magnetoresistance element at the FG magnet part 7b. The driving force is transferred to the outside by the driving transfer gear part 7a. As a result, the thickness of the FG magnet of the gear part can be obtained as the large value, and the reliability is improved.  At the same time, the inertial mass of the motor becomes large when the capstan motor is rotated and driven, and the rotating accuracy of the motor can be improved.

Title: Information recording carrier
Inventor: NAKAHARA TAKASHI
IPC: G11B7/2548
Filed: 1987-04-14
Abstract: PURPOSE:To permit correction of various deformations of an information recording carrier by providing a magnetic material layer which is attracted to a carrier imposing surface by the magnetic field generated from an information recording and reproducing device side to the above-mentioned carrier. CONSTITUTION:The magnetic material layer 5 is a metallic sheet consisting of a magnetic material playing the role of both as a protective member to protect an optical recording medium layer 3 against external environment, more particularly, dust flaw, external force, humidity, etc., and as a magnetic attracting member to magnetically attract the carrier to the recording and reproducing device and is preferably a soft ferromagnetic material. Said layer may be formed by sticking, for example, 'Permalloy(R)' foil having 0.1mm thickness by an adhesive agent. The use of the adhesive agent formulated to play the role of a heat insulating layer 4 is equally satisfactory in this case. The magnetic metallic sheet 5 fixed to a base plate 1 is magnetically fixed by a magnetic attracting means to the imposing base of the recording carrier provided in the recording and reproducing device. The deformations such as warpage and twist of the carrier which are undesirable for recording and reproduction are thereby easily corrected.
