Title: Carburetor of internal combustion engine for portable working machine
Inventor: KOBAYASHI TAKESHI
IPC: F02M17/06
Filed: 1989-06-01
Abstract: PURPOSE:To prevent the flow of fuel from being interrupted by the inclination of a carburetor by extending a semicircular passage from exhalation ports opened to the upper space of a fuel chamber and separated from each other to the vicinity of other exhalation ports, and communicating the terminal end of the passage to the atmospheric port. CONSTITUTION:Exhalation ports 57a opened to a chamber 73 are arranged apart from each other on the outer periphery section of the flange 75a of an outer pipe 75, even if a carburetor is inclined back and forth or to the right and left and one exhalation port 57a is submerged under the fuel oil level, the other exhalation port 57a is located above the fuel oil level and communicated to the atmospheric port 70. The exhalation port 57a submerged under the fuel oil level is extended to the portion adjacent to the other exhalation port 57a via a semicircular passage 57, thus no fuel is spilled from the exhalation port 57a to the atmospheric port 70 via the semicircular passage 57. The chamber 73 is invariably communicated to the atmosphere even if the carburetor is inclined, thus a fuel chamber 61 is invariably kept at the atmospheric pressure, and the flow of fuel from the fuel chamber 61 to a fuel nozzle 7 is not interrupted.

Title: Indicating meter
Inventor: HISHIKARI ISAO
IPC: G01D7/00
Filed: 1980-10-08
Abstract: PURPOSE:To make measurements and indications of measuring voltages which change rapidly with a simple and small sized constitution, by controlling the time of turned on and off of the light from the light source for making luminous scannings on the scale board in accordance with the input voltage. CONSTITUTION:When the location to be scanned initially of a scale board 6 is detected by a luminous scanner 5, a switch S of a lamp voltage generator 3 is closed through a scanning location detector 7. Then, a capacitor C is charged during the period from a time when an SCR is turned on through a diode ED until the SCR reaches the discharging period. When this charging voltage is impressed upon a comparator 2 as a reference voltage, compared with the input voltage from a terminal 1, and becomes larger than the input voltage, the output of the comparator 2 is inversed and an LED4 of a scanning light source is turned off. Moreover, the input voltage is displayed on the scale board as bar codes. Because of this simple and small sized constitution which does not use any needles, measuring voltage which change rapidly can be measured and indicated accurately.

Filed: 1990-05-30
Abstract: PURPOSE:To reduce power consumption by providing a MOS transistor to which constant mirror current is always supplied and a MOS transistor to which the mirror current controlled by means of an output logical level is supplied as current mirror circuits. CONSTITUTION:When the ECL logical level A of input changes to low, P-channel transistors 1 and 3 come to an ON-stage, and the mirror current is supplied to an N-channel MOS transistor 2. When a logical level O in an output terminal 53 changes to high, a P-channel MOS transistor for mirror current control 4 comes to an OFF-state and the mirror current is prevented from being supplied to the P-channel MOS transistor 3. Thus, the through current of the current mirror circuit in a normal operation state can be reduced and power consumption can be reduced.

Title: Vessel treating device
Inventor: AOKI AKIRA
IPC: B08B9/30
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent a vessel from tumbling in good performance. SOLUTION: A vessel transporting conveyor 3 is equipped with a number of sprockets S1-S20 and two belts 13A and 13B set over them. At the sides of these belts 13A and 13B, supply conveyors 4 and 4' are installed adjoiningly. The sprockets S1 and S20 adjoining to the supply conveyors 4 and 4' are arranged not movable in the axial direction of the drive shaft 11, while the other sprockets S2-S19 are movable in the axial direction of the drive shaft 11. If the two belts 13A and 13B expand thermally in the direction across the width when a vessel 2 is to be washed with hot water, the thermal expansion takes place from the side toward a gap 10 in the central part. Accordingly the gaps between the sides of the belts 13A and 13B and the supply conveyors 4 and 4' in their adjacent positions remain unchanged, so that the vessel 2 will never tumble.
