Title: Method for evading sudden attitude control operation of coaxial wrist robot
Inventor: KUMITANI HIDETOSHI
IPC: B25J9/10
Filed: 1995-03-03
Abstract: PURPOSE: To evade sudden operation as to the attitude control operation when the coaxial wrist robot is almost at a specific attitude. CONSTITUTION: The robot which has a coaxial wrist consisting of an α, a β, and a γ axis is placed in smooth attitude control operation from a point P to a point Q. An operation command is corrected which determines the attitude so that an operation track P' surely passing a range B wherein the robot is considered to be at the specific attitude is changed into P'A from a point P' before the robot enters a dangerous area where sudden operation is caused. In the figure, A is a singular attitude point. A wrist style determining process is performed almost when the coaxial wrist robot reaches the point A from P' so that flip/non-flip inversion is performed, and the abrupt rotations of the α axis and γ axis are evaded. The robot is made to gradually approach a broken line P'Q' from the point A and return to the original operation track from a point Q'.  The approach (to P') to the singular attitude is judged by comparing a β value at an interpolation point on the original operation track with a previously set critical value K of |β|. The wrist style determining process utilizes algorithm using an index for considering the (β, γ) value at a last interpolation point.

Title: Depressurization/pressurization type method and apparatus for sampling plasma
Inventor: YAMAZAKI YOSHIYA
IPC: A61K35/16
Filed: 1987-03-25
Abstract: PURPOSE:To sample plasma efficiently, by pressurizing a plasma bag after blood in a blood pool is sampled with the depressurization of the bag through a plasma separator to eliminate destruction of blood cells due to a blood pump. CONSTITUTION:A disposable section comprises a sampling needle 1, a membrane type plasma separator 3, a plasma bag 5, a plasma bag 4 and a tube for connecting these components. The blood sampling needle 1 is stuck into the plasma pool P to reduce pressure outside the blood bag 4 by a depressurization/ pressurization means 13 and blood anti-coagulated is sampled once into the blood bag 4 through a plasma separator 3. Then, the blood bag 4 is pressurized by the depressurization/pressurization means 13 to make the anti-coagulated blood pass through the plasma separator 3 at a relatively high flow rate so that plasma component alone is separated through a membrane to be sampled into a plasma bag 5 while blood cell-dense blood cleared of plasma is returned to a blood pool P. Thus, the sampling and returning of blood is performed through the same blood line and plasma separator thereby enabling efficient separation of plasma with a simplified blood circuit.

Title: Leg for electronic device
Inventor: TATSUMI TAKAHIRO
IPC: H05K5/02
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To reliably fix an electronic device with good working efficiency at a low cost without using screw, rivet and adhesive, by press-fitting a rubber a rubber leg having a through hole at its center on a pin on the bottom of the electronic device, and surrounding the side surface of the rubber leg with a rib around the pin. SOLUTION: A circular fixing through hole 3a is provided at the center of a rubber leg 3. On the other hand, a fixing pin 2a is provided with an annular rib 2b coaxial with the fixing pin 2a on a rotary platen 2. As the diameter of the fixing pin 2a is smaller than that of the fixing through hole 3a, the rubber leg 3 with a large amount of deformation can be press-fitted with a small force. Accordingly, as the influence of difference between the diameter of the fixing pin 2a and that of the fixing through hole 3a is small, stable holding force of the rubber leg 3 can be ensured. Further, when the rubber leg 3 has been fitted on the pin 2a, as the rib 2b surrounds the rubber leg 3, the rib 2b supports the rubber leg 3. Accordingly, the rubber leg 3 is not removed due to deformation of the rubber leg 3 or breakage of the fixing pin 2a.

Title: Light detector
Inventor: NAKADA YOSHIAKI
IPC: H01L31/107
Filed: 1990-03-20
Abstract: PURPOSE:To enhance a detection sensitivity and to reduce a multiplication noise by a method wherein the energy discontinuity amount of a conduction band at the heterointerface of a III-V compound semiconductor superlattice is larger than the energy discontinuity amount of a valence band and the energy discontinuity amount of the valence band is set to a prescribed value or lower. CONSTITUTION:Ionization ratio of electrons and holes which are accelerated by an electric field and which are entered a well layer form a barrier layer of a superlattice are designated as alphaSL and betaSL, respectively. The energy discontinuity amount  EC of a conduction band at the heterointerface of a III-V compound semiconductor superlattice is larger than the energy discontinuity amount  EV of a valence band, and the energy discontinuity amount  EV of the valence band is 0.2eV or lower, i.e., nearly zero. As a result, electrons contribute to the term of an electric field epsilon by an amount which is obtained the energy of  EC excessively. As a result, alphaSL is increased. On the other hand, since  EV is nearly zero, holes do not obtain the excessive energy as different from the case of electrons. Consequently, betaSL is not increased. That is to say, the difference between  EC and  V can be made large.

Abstract: PURPOSE:To obtain a metal oxide film having a controlled film thickness and excellent in optical property by gelating and film forming a metallic alkoxide stuck to the surface of a substrate by dipping into a solution and shrinking the metal oxide film by heating. CONSTITUTION:The substrate is dipped into the metal alkoxide solution and after pulled up, the metal alkoxide on the substrate surface is geleted by hydrolysis. Next, the metal oxide is film formed by removing a solvent and after that, by shrinking the metal oxide film by heating to control the film thickness, the desired metal oxide film is obtained. In this way, the thickness of the metal oxide film is finely adjusted by keeping the concentration of the metal alkoxide coating solution constant through a full period for pulling up the substrate, regulating the pulling-up rate of the substrate and further shrinking the film by heating after drying the coating film of the coating solution. As a result, the film having desired optical property is precisely and efficiently formed.
