Title: Optical disk
Inventor: NISHIZAWA AKIRA
IPC: G11B7/24047
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To facilitate sheet mounting and to improve the dynamic balance of an optical disk after mounting by providing an optical disk substrate with a sheet introducing projection on the side inner than its signal recording surface. SOLUTION: The disk substrate 1 is provided with the sheet introducing projection 3 which projects to the circumference of a central hole 2 and is tapered at its outer periphery on the inner peripheral side of the signal recording part of the substrate. A UV curing resin is dropped onto the front surface on the outer peripheral side thereof and a doughnut-like transparent sheet 5 is mounted thereon. As a result, the misalignment between the sheet 5 and the disk substrate 1 is prevented. A spinner for uniformly developing the UV curing resin 6 and regulating the film thickness to a proper thickness by removing the air bubbles is rotated.  The spinner is rotated in the manner described above and at the point of the time the UV curing resin attains the desired thickness, the rotation is stopped and, thereafter, the disk substrate 1 is taken out by holding its outer peripheral end, etc., by a disk substrate take-out device. The disk substrate 1 is transported to a UV curing device and is cured, by which the disk substrate 1 is completed.

Title: Train position detecting device
Inventor: UMEYAMA MASATOSHI
IPC: B61L25/02
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To enable high detection accuracy, even if a train travels at low speed, by detecting a time difference from reception of a radio signal till listening to a sound wave and calculating an absolute position of the train based on positional information of the radio signal according to this time difference. SOLUTION: An on-vehicle device 30 is connected with an automatic train stopping device 40 via a prescribed signal line and an absolute position calculating means is constituted of this on-vehicle device 30. For instance, a sound wave listening interruption signal is introduced into an on-vehicle processing part by listening to a sound wave S2 when this sound wave S2 comes in a sound wave receiver behind a radio signal S1. An isolating distance D with a ground device 20 at a present point of time is calculated. This isolating distance D is added to positional information on an installation position of the ground device 20 and a present position P of a train TR is determined.  At this time, because the installation position of the ground device 20 is a preliminarily fixed value, the finally obtained present position P of the train TR can be specified as an absolute position of the train TR in the railway line.

Title: Controlling method for pulse motor
Inventor: OOTA TOMOMI
IPC: H02P8/14
Filed: 1981-09-09
Abstract: PURPOSE:To shorten the time required for acceleration of a pulse motor by a method wherein a decision is made as to whether the motor is stepped out or not and the result is used in the selection of a prescribed speed pattern. CONSTITUTION:A pulse frequency pattern for changing or retaining a revolving speed is stored in a first region in a ROM2 and a self-activating pulse frequency for dissolving pulse motor maladjustment is stored in a second region. A microprocessor 5 decides whether the pulse motor is stepped out and, upon deciding it to be stepped out, the microprocessor 5 designates the second region in the ROM2 and, after activation by a self-activating pulse frequency, the pulse motor is accelerated by an accelerating pattern pulse frequency. And, when a decision is made that the pulse motor is rightly adjusted, the accelerating pattern pulse frequency is immediately used to activate and accelerate the pulse motor. This accelerates the pulse motor to a prescribed revolving speed in a short period of time.

Abstract: PURPOSE:To project properly a photographic picture and to prevent a damage to a film by placing a carrying section of a strip film onto a turntable and driving the turntable based on a command signal whether each frame of the film is placed laterally or longitudinally. CONSTITUTION:A film carrier 20 having the supply section 22 and the reception section 24 of the film is placed on the turntable 26. A video camera 32 is picked up by a carrying film transmitted and irradiated from downward. A film detection sensor existing on the upper part of the carrier 20 reads a notch of the film so as to detect the kind of the film and whether the frame of film is placed laterally or longitudinally. When the sensor 40 decides it as longitudinal pickup, a signal is transmitted from a controller 44 to a drive motor 94 to drive the turntable 26. Thus, the carrier 20 is driven together with the turntable 26 to rotate the frame of the film by 90 deg.. When it is decided as lateral position pickup, the motor 94 uses the said control signal and restores the table 26 to the original position.
