Abstract: PURPOSE:To accurately detect the apparently most strongly bent finger of a player by providing sensors to at least one finger selected out of the forefinger, middle finger, third finger, and little finger and the thumb of each hand of the player and detecting the bent amounts of the middle and proximal interphalangeal joints of the fingers or the middle interphalangeal of the thumbs and middle fingers. CONSTITUTION:Bend sensors 12b to 12e are respectively fitted to the forefinger 11b, middle finger 11c, third finger 11d, and little finger 11e of each hand of a player in such a way that the front ends of their bend detecting sections 13b-13e respectively come between the proximal and distal interphalangeal joints j2 and j1 of the fingers. The front end of the sensor 12a fitted to the thumb 11a comes between the middle and base interphalangeal joints j3 and j4 of the thumb 11a. Regarding the forefinger, middle finger, third finger, and little finger of the player, the bends of the joints j3 and j2 of the fingers are detected, but the bends of joints j1 nearest to the finger tips are not detected. Regarding the thumb, on the other hand, the bends of the joints j5 and j3 are detected, but the bend of the joint j4 which is the nearest to the thumb tip is not detected. When this sensor is used, the apparently most strongly bent finger can be detected.

Title: Oxygen analyzing instrument
Inventor: YAO SHINYA
IPC: G01N27/42
Filed: 1985-09-06
Abstract: PURPOSE:To improve the accuracy of oxygen measurement by providing filters respectively between a sample introducing means and oxygen pump and between the oxygen pump and circulation pump with regard to the circulating direction of a carrier gas. CONSTITUTION:The carrier gas and the oxygen released from a sample 6 fed together with the carrier gas are randomly mixed by a filter 19 provided on the upper stream side of the oxygen pump 8. The pulsation generated up to the inlet of the filter is consequently absorbed by the passage of the filter and is fed to the oxygen pump 8. The pulsation flowed by the suction pulsation of the circulation pump 5 is generated on the down stream side of the pump 8 as well but is absorbed by the filter 20 provided on the down stream side of the pump 8 and is prevented from being propagated to the pump 8. The pulsation of the flow in the pump 8 is thus suppressed from both the upper stream side and the down stream side and therefore, the pulsation of the current of the pump 8 is prevented. The accuracy of the oxygen measurement is thereby improved.

Title: Expansion device for expansion apparatus
Inventor: JIYON PII OROORIN
IPC: B60R21/26
Filed: 1994-08-22
Abstract: PURPOSE: To secure reliable operation and obtain stability by igniting an ignition material to increase pressure and destructing a destruction part of a cup member to advance a piston part from a non-erection position to an erection position. CONSTITUTION: When a vehicle collides, an ignition charge material in a casing 190 is ignited by an igniter 152. The combustion product discharged from the casing 190 pushes up an intermediate wall 165 of a cup member 150, flows into a combustion chamber 260, and ignites a propellant material 154. When gas pressure in the combustion chamber 260 is increased by the combustion of the propellant material 154 and reaches a predetermined pressure, a stress generation part of the cup material 150 is destructed. Consequently, a piston part of the cup material 150 moves upwards, and a plunger part 160 destructs a closing wall 90 and opens an opening 77 to release gas from a storage chamber 44. The pressurized combustion product in the combustion chamber 260 enters an outer part 60 of the storage chamber 44 to increase temperature, pressure, and volume of gas.  As a result, a large volume of gas inflates an air bag.
