Title: Intake-air device in internal-combustion engine
Inventor: AOYAMA SHIYUNICHI
IPC: F02B29/02
Filed: 1984-06-11
Abstract: PURPOSE:To enhance the efficiency of supercharge, in an engine in which each cylinder has high load and low load intake-air ports and each port has an independent intake-air passage, by introducing supercharge air into a stream at a predetermined timing with the use of a shut-off valve in a high load intake-air passage so that the counter flow of exhaust gas due to negative pressure may be prevented. CONSTITUTION:Each cylinder 1 has an exhaust valve 3A and two intake-air valves consisting of a normally open low load operating intake-air valve which is not shown and a high load operating intake-air valve 2A connected to a high load suction air passage 6A disposed therein with a valve 8. When the valve 8 is closed by an actuator 11 upon low load operation, pressurized air from a supercharger 12 is fed into the passage 6A until the termination of an suction stroke. With this arrangement, negative pressure generated in the passage upon suction stroke may be eliminated to prevent the counter flow of exhaust gas due to the negative pressure upon valve overlap, and as well it is possible to aim at sufficiently utilizing supercharge air.

Title: Acting method of photoelectron sensor
Inventor: BLUEMCKE THOMAS
IPC: G01S17/02
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide an acting method of a photoelectron sensor, particularly an optical barrier. SOLUTION: In this method, a light signal is transmitted to a monitored area by a light transmitter, and the transmitted and reflected light signal is received by a light receiver to supply the signal. Amplitude of the signal is examined for the presence of an object in the monitored area. In the case of the amplitude threshold value being over or under, an object detection signal is transmitted to put a photoelectron sensor, particularly an optical barrier, in action. At this time, prior to putting the photoelectron sensor in action, the threshold value is automatically set depending on the amplitude value generated in a specified measuring time interval in the state of an initialization process provided with a monitored area without an object existing, so that the threshold value is conformed to an acting condition existing in the initialization process.  Or the threshold value is automatically adjusted during the action of the sensor depending on the amplitude value generated in a specific measuring time interval, so that the threshold value is conformed to an acting state where each amplitude value is spread.

Title: Powder feeding structure for thermal spraying burner
Inventor: KONO HIROYUKI
IPC: B05B7/16
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To spray powder through a spray nozzle in a sufficiently uniformly diffused state by providing a throttling pipe portion consisting of a long-sized narrowdiameter tubular body and connected to an upstream side portion of a uniformly distributing path of a powder feeding pipe and forming in the throttling pipe portion a powder accelerating path for accelerating powder flow flowing into the uniformlydistributing path. SOLUTION: Because inner diameter of a throttling pipe portion 52 is set smaller than that of an upstream side portion of a lance side powder feeding pipe 29, flow of powder flowing together with oxygen as a carrier gas into the lance side powder feeding pipe 29 can be accelerated in a powder accelerating flow path 54 formed in the throttling pipe portion 52. Acceleration of the powder flow increases buoyancy of the powder and the powder flows along a bottom of a powder feeding tube 27. So called tube bottom flow can be avoided and a uniform flow of the powder can be obtained. In this state, the powder can be made to flow into a burner side powder feeding pipe 28 vertically divided by means of a partition plate 50 and influence of tube bottom flow due to gravitation can be almost avoided.

Title: Combustion control system
Inventor: YAMAMOTO YOSHIO
IPC: F23N3/02
Filed: 1978-09-25
Abstract: PURPOSE: To enable accurate control of quick responsiveness by continuously changing the input by driving the damper operation means which determines the damper opening located in the combustion air channel leading to the burner, thru the signal outputted by the detecter detecting the temp. of the object to be heated.  
     CONSTITUTION: Temp. set at the thermostat 22 is compared with the temp. detected at the room temp. detector 23 at the relative converter 24, servo-motor 18 is revolved to the direction such that the difference of the two is eliminated, and the servo-motor stops its revolution when the signal for setting the opening angle of the damper 17 coincides with the detected opening angle of the damper. Accordingly, once a temp. is set at the thermostat 22, input increases when the temp. at the room begins to lower, and vice versa, preventing the room temp. from rising or lowering from the set value, and enables the continous input change. Thru this system, continued upkeep of space-heating capability matching with the heating load is made possible, resulting in the constant maintenance of the space temp.

Filed: 1990-05-08
Abstract: PURPOSE:To prevent air bubbles from being mixed in to an ink passage from a needle member at the time of replacement of an ink cartridge by a method wherein at an ink passage to connect a needle member with an ink jet head, an ink chamber, of which capacity is contracted at the time of installation of an ink cartridge, and which forms a protruding shape meniscus at an ink insertion hole of the needle member is provided. CONSTITUTION:By sliding an ink cartridge 1 in the direction shown by arrow A to a carriage 6, an elastic member 4 comes into contact with a needle member 3. By sliding the ink cartridge 1 further, the needle member 3 is pushed by the elastic member 4, and a retaining element 5 gives piston motion, and the capacity of an ink chamber 13 is contracted. By this contraction of the capacity, a recessed shape meniscus M formed at a guiding port (3-a) of the needle member 3 expands into a protruding shape. When a protuberance (5-a) of the retaining element 5 comes into contact with the right side surface of a groove (7-a) of a supporting body 7, the needle member 3 sticks in the elastic member 4 and reaches an ink 2 in the cartridge 1. Since the meniscus at the guiding port (3-a) of the needle member 3 is expanding in a protruding shape, air bubbles do not enter the inside of the needle member 3.
