Title: Differential refractive index detector and liquid chromatography having the same
Inventor: TOKIEDA TSUNEMI
IPC: G01N30/02
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To perform an efficiently analyzing operation without personal difference to judge a stable state by checking the stable state while replacing an eluent, further allowing the eluent to flow only to a sample cell, and checking whether it is an analyzably stable state or not. SOLUTION: A start is input from an input unit 4. A three-way solenoid valve is intermittently connected by driving a three-way solenoid valve driving circuit 6. An eluent flowing through a sample cell is intermittently fed to a reference cell, foams in the sample and reference cells are excluded and the eluent is roughly replaced. After this operation is finished, the valve is opened, and eluent flowing through the sample cell is continuously fed to the reference cell. If a drift value and a noise value calculated from a refractive index difference signal by a digital calculator 2 are both limit values or more already input by the unit 4, the operation is finished. If they are both the limit values or less, a channel of the valve is switched, a flow of the eluent of the reference cell is stopped, the eluent is continuously fed only to the sample cell.  If the drift value and the noise value are the limit value or less, an arrival at the analyzable state is output from an output unit 5 and informed.

Title: Field effect semiconductor device
Inventor: HIROSE MAYUMI
IPC: H01L29/80
Filed: 1985-09-25
Abstract: PURPOSE:To eliminate characteristic deterioration upon microminiaturizing by forming an n-type layer to become an active layer and an n<+> type layer to become source and drain regions on a p-type GaAs substrate having 10<12>-10<16>/cm<3> of acceptor density, and forming an ohmic electrode on the back surface of the substrate. CONSTITUTION:An n-type operating layer 12 to become a channel region is formed on the surface of a p-type compound semiconductor substrate 11 having 5X10<14>/cm<3> of acceptor density, and a Schottky gate electrode 13 made of tungsten nitride is formed on the surface. An n<+> type source region 14 and drain region 15 which have deeper density than the layer 12 by ion implanting are formed on both sides of the substrate through the electrode 13, and source and drain electrodes 16, 17 are respectively formed on the surfaces. An ohmic electrode 18 is formed n the back surface of the substrate to be shortcircuited with the electrode 16. Since the barrier capacity for the channel of the substrate is strengthened by using a p-type substrate, a substrate current is suppressed to resultantly improve K value.

Abstract: PROBLEM TO BE SOLVED: To provide a strap for a stick for preventing from accidentally moving to a longitudinal direction of a shaft section by forming a detachable flexible coupling body for connecting to a strap main body and by disposing anti-shaft section skid proof means on the coupling body on which rubber or the like is adhered. SOLUTION: A coupling body 2 connected to a strap main body 1 is formed in a wide belt-like shape or a string-like shape to removably couple winding to a shaft section 3 of a stick, and is formed flexible. On a surface touching to the shaft section 3 of the coupling body 2, a skid-proof means 4 attaching rubber, silicone or the like is disposed. The skid-proof means 4 may well be formed by attaching rubber, for example, the entire surface of the coupling body 2, or to some lines of stripes, or by processing dots to a plurality of circles. When the coupling body 2 connected to the strap main body 1 is connected to the shaft section 3 of the stick, the skid-proof means works to prevent from accidentally removing at the shaft section 3.

Title: Wire bonder
Inventor: ISHIBASHI TAKAO
IPC: H01L21/60
Filed: 1989-08-14
Abstract: PURPOSE:To improve efficiency by a method wherein pattern recognition is performed as to a special pattern part at one constant point on a chip part after position correction and before bonding so that if the pattern matches with a stored recognition pattern for position confirmation, bonding is done and if it does not match, processing proceeds to a subsequent wiring substrate. CONSTITUTION:A bonding control mechanism 17 controls a stage 3 and moves to a position of a position correction mark 7 previously stored for a chip part 1, and requests output of position correction data from a control circuit 14. The control circuit 14 records a position correction recognition range 9 with a television camera 11, and an image processing circuit 12 creates a binary image. The image is compared with a binary image stored in a position correction reference pattern memory 15 for the chip part 1 to output a difference from a reference pattern, i.e., position correction data, which has been factorized in the horizontal direction (X), the vertical direction (Y) and the rotary direction (theta), and the bonding control mechanism 17 corrects the position of the chip part 1 based on the output data. Thus, it is possible to prevent defective parts from flowing to subsequent process due to erroneous mounting, and therefore efficient wire bonding can be performed.

Title: Clipping processing method
Inventor: KATAOKA HISAAKI
IPC: G06F3/153
Filed: 1985-09-24
Abstract: PURPOSE:To perform the graphic display at a high speed by putting an area comparison step into the generation processing step of digital segments. CONSTITUTION:In an area comparison step 8 it is decided whether or not the point coordinates Xi and Yi of a digital segment of a vector are set outside the area of a window 100. For instance, a start point PE2 is defined with a vector 102 and X is decreased one by one each time. Thus the over-decision is defined for the step 8 when Xi<XL is satisfied and the processing is through with the corresponding vector. While a start point PS3 is defined with a vector 103 and Y is increased one by one each time. Then X is processed against said increment and therefore the over-decision is defined for the step 8. Thus the processing is through with the vector 103.

As a result, one end of a lever 41 of the final step is moved to the direction shown by an arrow F at a prescribed magnification by the action of levers 39 to 41 with thin-welled parts 42 to 44 as fulcrums. When a voltage is applied so as to dissolve distortion generated in the element 27a, the levers 39 to 41 are returned to their former stationary positions by the spring elasticity at the thin-walled part of the arm 25a. At this time, the vibrator 22a is interlocked to the arm 25a and is moved.

Title: Optical input josephson logic circuit
Inventor: NAKAHARA KOJI
IPC: H01L39/22
Filed: 1990-08-13
Abstract: PURPOSE:To facilitate thermal insulation from outside by using an external optical signal so as to switch a Josephoson junction element directly thereby attaining high speed operation and eliminating crosstalk between signal lines. CONSTITUTION:A baffle circuit decides an output signal depending on a direction of a current flowing in a load inductance 17. In this embodiment, a direction of a current from a DC constant current source 13 flowing in a Josephson junction element 12 through a resistor 15 is defined as '1' and the reverse direction is defined as '0'. A light of a set signal through an optical fiber 18 switches a Josephson junction element 11 in the superconducting state to the voltage state and its reaction brings the Josephson junction element 12 to the superconducting state. Since the current flows from the resistor to the Josephson junction element, the output goes to '1'. When the Josephson junction element 11 is brought into the superconducting state, the output goes to '0'. Thus, flip-flop operation is implemented by the optical input.
