Title: Skewed brushless rotary electric machine
Inventor: MOMIYAMA MAKOTO
IPC: H02K29/00
Filed: 1987-06-30
Abstract: PURPOSE:To reduce a cogging torque and the rate of decrease of an induced voltage by setting the number of salient poles of a stator field core as 1.5 times the number of magnetic poles of a rotor permanent magnet and by applying skew to said rotor permanent magnet or stator field core. CONSTITUTION:In a synchronous type brushless motor, in which the numbers of magnetic poles of a rotor permanent magnet, slots of a field core and driving AC phases are respectively 6, 9 and 3, such skew as shown by a broken line is applied to a ring-shaped plastic permanent magnet 1 fastened on the outer periphery of a rotor by 1/2 of a slot pitch between slots opened in a three-U, V, W-phase excited stator field core 2. Thus, much cogging torque generated cancels each other and the rate of decrease of an induced voltage also is small as compared with that of the existing 1 slot skew.

IPC: G01N33/52
Filed: 1983-09-06
Abstract: PURPOSE:To shut off substantially the intrusion of air, etc. by providing a flexible sheet cover which is provided with an aperture only at the inlet for insertion of a lever and opens and closes without disturbing the discharging of a slide for analysis into a discharge port while the slide is extruded and pressed by an extruding lever. CONSTITUTION:An extruding lever 7 advances to enter the inside of a cartridge 1 and pushes the rear of a slide 4 for analysis when the stage for discharging the slide for analysis is started. The slide 4 advanced by said lever is discharged through a slide discharge port 2. The lower part of a flexible sheet cover 8 is lifted by the front end of the slide 4. The slide 4 is extruded up to the rear end thereof from the cartridge 1 and when the slide is completely discharged, the lever 7 retreats automatically. The cover 8 is reset to the home position by the elasticity of the sheet and seals the port 2 until the stage for discharging the succeeding slide is started thereby shutting off the intrusion of air, etc. The deterioration in performance during storage of the slide for analysis is prevented by shutting off the intrusion of the air, etc. in the above-mentioned way.

Title: Contact combustion type carbon monoxide sensor
Inventor: OISHI KAZUHIRO
IPC: G01N27/16
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To accurately detect carbon monoxide in atmosphere without being affected by carbon dioxide or steam by arranging a carrier layer where a detection element has activity against carbon monoxide around a conductor and arranging a carrier layer where a temperature compensation element does not have any activity against carbon monoxide around the conductor. SOLUTION: The carrier layer of a temperature compensation element 1 and that of a detection element 2 are both in granular shape. Normally, alumina is used as a carrier layer material and γ-alumina that carries a catalyst is used for the detection element 2, while α-alumina is used for the temperature compensation element 1. Normally, platinum is preferably used for a conductor. A bridge circuit is used by using the detection element 2 that carries palladium and the temperature compensation element 1 with a different particle diameter to form a contact combustion type carbon monoxide. Carbon monoxide in atmosphere can be detected accurately without being affected by, for example, carbon dioxide or steam.

Abstract: PROBLEM TO BE SOLVED: To improve function by a method wherein a labyrinthine weir edge body formed as seen in the planate view in a shape projecting alternately forward and rearward is provided at an overflow section at the upper edge of an opening/shutting door leaf. SOLUTION: For instance, a door leaf 10 is provided at a place between bearing walls 2 forming a watercourse so that the door leaf can be lifted up and down, and a roller gate 1 is constructed with a labyrinthine overflow section 20 provided at the upside of the door leaf main body. The overflow section 20 is formed by erecting a weir board body 21 in a triangular wavelike shape projecting alternately toward the upstream side and the downstream side as seen in the planate view at a top board 11B provided at a place between side pillars of the door leaf main body.  The door leaf 10 checks water at a closing position contacting with the river bed surface 3 while letting water overflowing the overflow section 20 flow for keeping the water level constant, and when the amount of inflow increases abruptrly because of a flood or the like, the door leaf 10 is raised and water is discharged through a space between the lower edge of the door leaf and the river bed surface 3. As the length of the weir becomes long because of the zigzagging shape at the labyrinthine overflow section, discharge capacity can be made large while reducing man power and cost without requiring the gate to be built in a double stage structure and furthermore, the water level at the upper stream can be made constant.
