Title: Intake device of rotary piston engine
Inventor: KAWACHI MASAYUKI
IPC: F02B53/08
Filed: 1982-10-15
Abstract: PURPOSE:To enhance the output of an engine by simple constitution without causing any necessity for a supercharger or the like, by obtaining the supercharging effect resulting from a mutual intake inertia effect between cylinders and from an intake proper pulsation effect of each cylinder itself, when the two- cylinder engine of side intake port type is driven at a high speed. CONSTITUTION:When an engine is driven at a high speed, a compression wave, generated in a passage 16b at closing, is propagated to an intake port 3 immediately before full closing of a cylinder 1A with a 180 deg. phase difference due to the adequate length of a passage between intake ports 3, 3. Similarly thereafter, a mutual intake inertia effect is obtained between cylinders 1A, 1B. Simultaneously, an expansion wave generated in intake passages 16a, 16b by a start of intake of the intake port 3 in each cylinder, is propagated as a secondary pulsating wave to the intake port 3 immediately before full closing, and an intake proper pulsation effect is obtained by each cylinder itself. Accordingly, intake air from the intake port 3 immediately before full closing is forced to enter a working chamber 8, thus supercharging is performed.

IPC: H04L12/02
Filed: 1990-07-12
Abstract: PURPOSE:To reduce the communication cost without laying plural telephone lines by transmitting gathered data, to which the subaddress designated by a designating means is added, to an optimum data output device through an integrated service digital network ISDN. CONSTITUTION:The designating means designates subaddresses of ISDN basic interface of optimum data output device 29 to 31 (electronic printer 29, high- speed printer 30, and image printer 31) corresponding to data classifications added to gathered data based on data classifications recognized by a data classification recognizing means. A data gathering device 21 transmits gathered data, to which subaddresses designated by the designating means are added, to optimum data output devices 29 to 31 through ISDN 25. Consequently, optimum data output devices corresponding to data classifications of gathered data are dynamically selected without intervention of an operator, and gathered data are transferred and outputted to optimum data output devices. Thus, the increase of the cost is prevented without laying plural telephone lines.

IPC: G11B7/125
Filed: 1993-07-23
Abstract: PURPOSE:To improve the S/N of a reproducing signal in the manner of accurately forming a recording pit by a semiconductor laser and to prevent the semiconductor laser LD from being damaged due to the overshooting of a driving current for the semiconductor laser at the time of recording, by a simple constitution. CONSTITUTION:The current to be supplied to the semiconductor laser LD is switched by a recording signal generating circuit 1 of a recording APC circuit in accordance with the signal of a light emitting pulse (a). When the current is supplied to the semiconductor laser LD by the switching operation, the light is emitted from the semiconductor laser LD. The emitting power of the semiconductor laser LD is detected by a photodiode PD for monitoring. By a high speed current control part 2, the current 12 is controlled so that the detected light emitting power becomes the predetermined value. By a low speed current control part 3, a current I1 controlled with temperature is supplied independently of the detected light emitting power.

Title: Laser range measuring device
Inventor: NISHIMURA HIDETOMO
IPC: G01S17/08
Filed: 1984-09-03
Abstract: PURPOSE:To obtain a device which take measurement of distance in its circumference by allowing a reflecting mirror for laser light to rotate freely in two axial directions. CONSTITUTION:The reflecting mirror 19 which reflects laser light from a laser light source 1 is allowed to rotate freely in the two axial directions. Then, the reflecting mirror 19 is so rotated that the optical path is on a plane formed of the reflecting mirror 19, a reflection point, and a photodetection part 9, and consequently the range is measured while a scan is made on a straight light in the internal surface of a wall 14. The laser light from the light source 1 is reflected by the reflecting mirror 19 and passed through a window 21, and reflected light from the wall 14 is detected by the photodetection part 20 through a window 22. Consequently, the distance of the peripheral wall 14 of a container is measured only by moving the reflecting mirror 19 without rotating a rack 10 nor the container 11, thereby shortening the measurement time.
