Title: Motor-stop control method and information storage medium
Inventor: ANDO TOSHIYUKI
IPC: H02P29/00
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a motor-stop control method, in which the high-frequency resonance of the so-called 'mechanical system' is not excited and in which a high-speed fall control operation can be performed by a method, wherein when a motor is controlled so that an object, to be controlled which is driven in a certain state is stopped, an optimum desired value is input. SOLUTION: In this motor-stop control method, the target angular velocity of a drive part 2 and a target angular acceleration as a feedfoward are expressed by a polynominal expression regarding the time on the basis of an evaluation function, i.e., on the basis of an acceleration pattern in which the square of the integrated value of the twice-differentiated value of the angular acceleration or the acceleration of controlled object 1, becomes minimum. By using a polynominal expression, the target angular velocity for every sampling time and the target angular acceleration as feedforward are computed by a computing and control part 3. According to the difference from the converted value of the angular velocity or the velocity at every sampling time of the object 1, the drive part 2 is controlled.  By controlling the drive stop for the object 1 is controlled, while the high-frequency resonance of the so-called mechanical system is not excited, and control for high-speed fall can be performed.

Title: Printer
Inventor: SHINKAI YOICHI
IPC: B65H7/14
Filed: 1993-10-22
Abstract: PURPOSE:To maintain a high accuracy detection of paper over a long period of time by installing an optical paper detecting sensor in a zone where paper passes through but is outside a printing zone. CONSTITUTION:When paper 1 is wound around a platen 7, light which is emitted from a reflection type photo sensor 11 is reflected by the paper 1 and is received by the sensor 11. When the paper 1 is not wound around the platen 7, the light is reflected by the platen 7 and is received by the sensor 11. Since reflection power is different between the paper 1 and the platen 7, the presence of the paper is detected based on the difference in the reflection power. The reflection type photo sensor 11 is installed in a zone 1b where the paper 1 passes through but is outside a printing zone 1a. As a result, it is possible to detect the paper 1 with high accuracy over a long period of time. Since printing striking is not applied to the platen 7 by a printing head, its surface is smoothed and its reflection factor is not becoming greater.

Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To restrain the generation of NOX by widening a spark gap than convential one, applying a high voltage in an ultra short pulse, enhancing ignition performance by combining an intake port strengthened in swirling and thereby increasing burning speed in a lean burn gas engine. SOLUTION: Intake air 300 enters into a combustion chamber 103 from a swirl/tumble strengthened type intake port 105 to be compressed after an intake valve is closed, a high voltage is applied to a spark plug 104 by a pulse power ignition system 109 when a piston 101 reaches its upper dead center to ignite, to burn gas and to exhaust from an exhaust port 107. Since the high voltage in an ultra short pulse shorter in boosting time than conventional one is applied by the pulse power ignition system 109, and the spark gap is widened than conventional one, arc discharge takes place after streamer discharge in a discharge mode, so that ignition performance can be excellent. Since the intake port 105 is so bent as to allow the mixed gas to swirl and tumble in the combustion chamber 103, the generation of NOX can be restrained by means of high ignition performance and combustion of high efficiency.
