Title: Method for controlling patient bed transfer device
Inventor: OKAMOTO KENJI
IPC: A61G1/00
Filed: 1988-03-09
Abstract: PURPOSE:To prevent a belt from being chocked up and/or becoming loose by mounting tension rollers detecting the slack of the belt onto a patient bed transfer device, and thereby regulating the rotating speed of a belt roller based on the detected slack of the belt. CONSTITUTION:Tension rollers 21 are provided for an upper belt 10 rolled out of belt rollers 8 and 9 behind an insertion plate 7, and are supported so that the belt 10 can not be slacked while the belt is being pressed by a spring 22. The insertion plate 7 is affected in considerable change in speed due to resistance caused when the insertion plate 7 is inserted between a patient and a bed, the belt 10 is thereby slacked much greater to the extent that the slack can not be absorbed only by the tension rollers 21. The displacement of the tension rollers 21 is measured by a displacement measuring sensor so that the belt rollers 8 and 9 are controlled in such a way that the slack is decreased. Namely, when the insertion plate 7 is moved forward, if the belt 10 becomes loose, the belt rollers 8 and 9 are decreased in rotating speed. And if the belt 10 is under extreme tension on the contrary, the belt rollers 8 and 9 are increased in rotating speed.

Title: Scanner synchronous circuit
IPC: H04N3/08
Filed: 1992-03-16
Abstract: PURPOSE:To secure the stable and accurate synchronization a TV frame synchronizing signal and a scanner by producing a window signal which is synchronous with the TV frame synchronizing signal and selecting the center position detection signal of the scanner which performs the optical reciprocating scanning based on the window signal. CONSTITUTION:The infrared rays converged by an infrared lens 11 are reflected on a scanner 10 which is driven by a scanner driving circuit 20. Thus the infrared image of a single frame is produced. At the same time, an optical sensor 31 detects the center position of the image and generates the pulse output when the oscillating angle of the scanner 10 is set at 45 deg.. The center position detection signals are produced twice in both going and coming-back modes. Then only the center position detection signal that is produced in the going mode is taken out by the window signal produced by a window signal generating circuit 50. Thus a window circuit 60 outputs the center position detection signal of only the going mode of the scanner 10. Therefore the accurate synchronization is secured between a TV frame synchronizing signal and the scanner 10.

Title: Device for controlling air-fuel ratio for internal combustion engine
Inventor: KUSHI NAOTO
IPC: F02D41/04
Filed: 1986-03-17
Abstract: PURPOSE:To improve drivability and emission by providing a transient/steady judging means for judging whether the operating condition of an engine is in a transient operating condition or in a steady operating condition, and an injection quantity operating means for operating an injection quantity based on an estimated value. CONSTITUTION:The moderating control value is stored in a RAM105 after the detected value of pressure in side an intake pipe from a pressure sensor 3 is subjected to A/D conversion. When an engine is in a transient operating condition, the quantity of intake air at the point of time when fuel actually arrives at a combustion chamber is estimated from the latest stored value and the stored values at the last and before the last detected timings, using a defined formula. Also, when the engine is in a steady operating condition, the latest stored value as it is, is used as an estimated value. And, the final injection quantity is obtained from these estimated values and, based on this, a fuel injection valve 7 is controlled via a driving circuit 108. As a result, responsiveness is improved in the transient operating condition of the engine, while variation in injection quantity caused by variation in the estimated value can be eliminated in the steady operating condition.

Abstract: PURPOSE:To prevent step-out when a rotor having stopped poles is again rotated by exciting a phase previously selected at a first stage and a phase except a phase at a position separated at 180 deg. except the phase at a second stage, and moving the poles of the rotor. CONSTITUTION:In the case of a 4-phase pulse motor to be driven by a two-phase excitation, when IV-I phases are excited by a phase deciding current, a rotor is not moved if poles of the rotor is disposed at positions of the IV-I phases, and moved to a position R2 of the IV-I phase if the poles are disposed at a position of I-II phases or position R1 of III-IV phases. Then, when the I-II phases except a phase disposed at a position separated at 180 deg. from a position F1 of the phase excited at a first stage is excited except the phase excited at the first stage by a phase detecting current at a second stage, since the IV-I phases are excited at the first stage, the poles of the rotor are disposed at the position R2 of the IV-I phases or the position of the II-III phases, and always moved to a position F2 of the I-II phases. Accordingly, a pulse motor is not stepped out when the rotor is again rotated.

Title: Intake device for engine
Inventor: SUGIO TOSHIYA
IPC: F02B31/00
Filed: 1986-03-17
Abstract: PURPOSE:To improve an engine output, by generating a swirl when an engine is in a low speed even if it is high loaded, in case of the engine equipped with a swirl control device. CONSTITUTION:An intake port 3, which connects with a cylinder 1, has a secondary intake passage 7, equipped with an opening and closing valve 8, and a primary intake passage 6 bypassing the opening and closing valve 8. An engine generates a high swirl in the cylinder 1 only from the primary intake passage 6 if the opening and closing valve 8 is closed, and the engine, while weakening generation of the swirl, inducts a large amount of intake if the opening and closing valve 8 is opened. The engine obtains stable combustion by the high swirl, when the engine is low loaded, while improves an output by the large amount of intake when the engine is high loaded, but the engine, even when it is high loaded and in a low speed, generates the high swirl by closing the opening and closing valve 8 because knocking is not easily generated, and a high output is obtained by performing stable combustion.
