Title: Conveyer
Inventor: KAWAMURA YOSHITAKA
IPC: B65G25/02
Filed: 1988-10-21
Abstract: PURPOSE:To enable a heavy-duty conveyer to perform two reciprocating strokes by providing rotors on a movable side and fixed side rotatably around the respective vertical axes of carrying article holding bodies and spacedly in the moving direction of the carrying article holding bodies respectively and connecting the respective eccentric positions by a rod. CONSTITUTION:When a rotary arm 28 is rotated half revolution intermittently, a carrying article feeding bar 13 is reciprocated twice of eccentric quantity E per half revolution through a connecting member 14. At this time, a rotary disk 22 does not rotate. On the other hand, whenever the rotary arm 28 is stopped and the rotary disk 22 is rotated half revolution intermittently, the connecting member 14 pivotally secured at one end of a fixed connecting rod 24 and a carrying article feed bar 13 are reciprocated twice of eccentric quantity (e) per half revolution. This constitution allows the title conveyer to reduce the shock caused by the stop in the beginning of a movement as well as to perform a reciprocated stroke different from a feed stroke.

Abstract: PURPOSE:To reduce adsorption of dust, organic substances, etc., and remove metallic impurities such as Cu by a method wherein oxidizing solution is added to fluoric acid solution and a surface which is made hydrophobic in the hydrofluoric acid is turned into a hydrophilic surface by the quantity of the oxidizing solution. CONSTITUTION:Wafers put in a carrier are dipped in a first washing bath in which SC-2 solution is stored for about 10 minutes.

Title: Closest object detecting device
Inventor: MORI KENICHI

Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To apply an autofocus IC as a passive type distance measuring device which has been mainly used in a range-finder of a camera or the like to the detection of a closest object (toilet user) for the purpose of automatic rinsing of a toilet. SOLUTION: In an autofocus IC 02 as the present device, when an object approaches a very near position of a passive type distance measuring device having photo sensor arrays 3A', 4A' making a right and left pair corresponding to a pair of right and left imagery lenses, the peripheral parts of the photosensor arrays 3A', 4A' are covered by the object, the luminance of the image picked up by the photo sensor arrays 3A', 4A' decreases, and response of a photosensor becomes slow. A closest object detecting means 01A in an MPU 01 detects that the response time of all photosensors constituting the photosensor arrays 3A', 4A' is sufficiently longer than the case that the object does not exist, from the sensor response shortest signal τmin showing the timing of the fastest response of a photosensor of the IC 02.  When the distance fan object to be measured which distance data 9 outputted from the IC 02 show is not at least a specified value, it is judged that the object to be measured is in a very near distance.

Abstract: PURPOSE:To make generated voltage uniform and to prevent deterioration in performance of an electrode caused by partial load concentration to lengthen the life of a cell by sequentially increasing reaction gas permeability from the inlet side toward the outlet side, through which a fuel gas and an oxidizing agent gas flow, in each electrode base material. CONSTITUTION:Gas permeability in a fuel electrode base material 5 and that in an oxidizing agent electrode base material 6 in a unit cell 11 are sequentially increased from the inlet side toward the outlet side by sequentially decreasing the coating amount of a water repellent fluororesin dispersion solution the gas flow inlet side toward the outlet side in each electrode material. The amount of reaction gas permeating the electrode material is increased toward the gas outlet side, and voltage on the gas inlet side is lowered than that based on partial pressure characteristic by current technology, and voltage generated in the unit cell is made uniform. When air is used as the oxidizing agent gas, variation in air permeability is unnecessary and increase in gas permeability from the inlet side toward the outlet side is also unnecessary.

Abstract: PURPOSE:To simplify the construction of an electrode part for generating an electron beam by realizing two-stage acceleration by means of a cathode provided with a directly heating type filament and giving an ion acceleration function to an initial stage accelerating cathode so as to eliminate all subsequent acceleration electrodes after an anode. CONSTITUTION:An electron beam 5 is generated by a direct-heating type filament for being accelerated at a high voltage by a lead-out electrode 4. Negative potential more intense than that on an anode 2 is impressed on the lead-out electrode 4 to realize the initial acceleration and the accelerated electron beam 5 passes through a small diameter tube, whose degree of vacuum is gradually lowered, to reach a target chamber 8 while being converged by current lenses 7a-7c and ionizes gas introduced inside after being defocused due to collision with and ionization of the electron beam 5.
