Title: Optical information processor
Inventor: TAKAHASHI NAOMASA
IPC: G11B7/085
Filed: 1989-04-21
Abstract: PURPOSE:To make a movable part light in weight, to accomplish high speed access and to make it possible that a small driving current is sufficient by moving a slider so that an optical means may be moved in an access direction. CONSTITUTION:The movable slider 10 is provided in the radial direction of an information storing medium 2. By moving the slider 10, the optical means 3a and 3b coupled with the slider through a supporting spring mechanism 11 are integrally moved and coarse access is accomplished. By deforming the part of the supporting spring mechanism 11, the optical means 3a and 3b can be finely displaced and precise access is accomplished. Then, the coarse access is accomplished by moving the optical means equipped only with the condensing means 3a of an optical system, so that the most parts of a magnetic circuit and the optical system which are the cause of increasing weight are eliminated from the movable part of an access system. Thus, the movable part is made light in weight and the high speed access is accomplished, and also smaller driving current is sufficient to apply.

Title: Semiconductive pressure sensor
Inventor: KUME MASAHIRO
IPC: G01L1/22
Filed: 1985-05-14
Abstract: PURPOSE:To reduce the variation in the temp. drift of a zero point and sensitivity, by mounting a resistance controller for applying the temp. drift compensation of a zero point and sensitivity to the output of a bridge and performing the level adjustment of the zero point and sensitivity. CONSTITUTION:When there is no application of external pressure, the output voltage of a bridge can be brought to zero by connecting a resistance controller 19 between points (a), (c) and controlling the resistance values of resistors 20, 21. Because the temp. coefficient of the resistance between a resistance arm ad and a resistance arm cd constituting a bridge circuit is small as compared with resistors 11, 12, there is no effect in the temp. drift of an output zero point even if the divided resistors 20, 21 of the resistance controller 19 are connected between the resistance arms ad, cd in parallel. The temp. drift compensation of the output sensitivity when pressure was applied is performed by connecting a temp.-sensitive resistor 15 comprising the same material of the semiconductive electrostriction resistors 11, 12 to the bridge circuit in series.

IPC: H04M3/22
Filed: 1988-04-27
Abstract: PURPOSE:To always grasp the operating status of extensions in an opposite exchange by using a TS 16 not specified by the TTC standards so as to send information such as extension operating status between exchanges. CONSTITUTION:A CPU 10 controlling the operation of an exchange uses the TS 16 not specified by the TTC standards and a bit corresponding to a TS 16 transmission storage means 8 is written every time the extension operating status is changed. Thus, a TS 16 reception storage means 9 of an opposite exchange is varied. Similarly, every time the operating state of the extension is varied in the opposite exchange, the TS 16 transmission storage means 8 is rewritten to vary the TS 16 reception storage means 9 of its own exchange. A CPU 10 checks the content of the TS 16 reception storage means 9 to recognize the extension operating status of the opposite exchange. Thus, the busy state of opposite party is recognized before dialing.

However, since the paper P is bent (a) and its part between the rollers 18, 18 and the platen 10 is maintained in a free condition, the paper P is moved as one body with the platen 10 irrespectively of the relationship of l1<l2, namely, even when the feeding amount by the rollers 18, 18 is insufficient. Accordingly, the paper P is prevented from slipping on the peripheral surface of the platen 10 or being transversely staggered, so that clear images can be constantly formed on the paper P.

Abstract: PURPOSE:To reduce the generation of dispersion of the film quality and film thickness of a thin film to be formed on the surface of the sample and the generation of noise in a title equipment by a method wherein a hole having its edge processed in a taper form or in an R shape and an electrode, which generates low-temperature plasma in the space including the sample by feeding high-frequency power thereto, are provided at the surface of the equipment, which opposes to the sample. CONSTITUTION:The interior of a vacuum container 11 is vacuum-exhausted by a vacuum pump 18, and after that, compound gas containing the constituent element of the thin film to be formed on the surface of a sample 12 is introduced in the vacuum container 11 from the hole 16a of an electrode 16 at a constant flow rate. The pressure in the interior of the container 11 is held at a constant pressure by operating a pressure control unit 20 and the sample 12 is heated and controlled by a sample stand 13 to a constant temperature. Then, hihg-frequency power is fed to the electrode 16, whereby low-temperature plasma is made to generate in the space including the sample 12. As the edge part of the hole 16a of the electrode 16 is kept processed in a taper form or in an R shape, an electric field is hard to concentrate thereon. Accordingly, no spark is generated in the hole 16a. By this constitution, the reproducibility of deposition is improved. As a result, the generation of dispersion of the film quality and film thickness of the thin film to be formed on the surface of the sample and the generation of noise are reduced.
