Abstract: PURPOSE:To stabilize the molten state of a brazing material even when the thickness and the shape of a frame and the operating speed of a bonding head are changed and to obtain a binding operation whose accuracy and quality are high by a method wherein the temperature of the frame is measured at the bonding operation and the operation of the bonding head is controlled. CONSTITUTION:A clamper 9 conveys a die pad 6 of a lead frame 5 to a bonding point. The temperature of the die pad 6 is measured by using a temperature measuring instrument 11. Whether the measured temperature has reached a set value or not is judged by using a control system 12. When it has reached the set value, an instruction is output to a driving system 4 and the operation of a bonding head 1 is started. When the measured value has not reached the set value, the operation of the bonding head 1 is on standby; the operation of the bonding head 1 is started after the temperature of the die pad 6 has been raised to the set value. A die 3 is fixed and bonded onto the die pad 6 by the lowering operation of the bonding head 1. A clamper 10 conveys the lead frame 5 when a series of operations have been finished; a next die pad 6 reaches the bonding point.

Title: Color display panel
Inventor: OGUCHI KIKUO
IPC: G09F9/30
Filed: 1984-06-11
Abstract: PURPOSE:To increase the symmetry of a color display panel and to improve the display grade thereof by constituting said panel of 4-color picture elements consisting of three primary color picture elements added with colorless picture elements. CONSTITUTION:The liqid crystal panel 5 making a color display is constituted of 4 kinds of the picture elements; red picture elements (R)6, green picture elements (G)7, blue picture elements (B)8 and colorless picture elements (W)9. These picture elements consist of the color picture elements of the three primary colors red, green and blue plus colorless picture elements. Since the picture elements are constituted of 4 kinds in the above-mentioned manner, the degree of freedom in the picture element array is considerably increased and particularly the array in which the picture elements of the same colors are vertically or laterally continuous can be easily avoided. An example is taken here of the red picture elements R: Said elements consist of the array where the lower right and upper left picture elements are continuous with each other and the array in which the upper right and lower left picture elements are continuous with each other. The elements are not symmetrical on the right and left when the local part such as two horizontal lines is viewed but the straight lines of the same picture elements declining toward the right and the straight lines declining toward the left exist when at least >=4 horizontal lines are viewed. The lateral symmetry is thus improved.

Abstract: PURPOSE:To prevent busyness and to reduce the transmission delay by measuring the degree of the performance of mass-arrival of transactions in the unit of lines periodically and varying the return time of a transmission confirming signal according to the fluctuation of the burst traffic characteristic value and the fluctuation of number of buffers in use. CONSTITUTION:A burst traffic characteristic value decision means 2 obtains a ratio of number of transactions (t) reached actually to a maximum transaction number T able to be reached in the unit time. A not-in-use-buffer-number decision means 3 obtains number M of buffers not in use in the unit time. A transmittal confirming signal transmission means 4 decides a deviation  S from a standard interval timer value S0 as  S=alpha.B.1/N. Then the time interval S from the arrival of transaction till the return of a transmittal confirmation signal is selected as S=S0+ S. Thus, the transmittal confirming signal is sent slowly with respect to the transaction reached in a burst way the transmittal confirming signal is sent quickly with respect to the transaction reached in a non-burst way.

Title: Gas sensor
Inventor: TAKENAKA HISATAKA
IPC: G02F1/03
Filed: 1995-05-18
Abstract: PURPOSE: To obtain a gas sensor utilizing a light waveguide withstanding repeated use by forming the light waveguide from fluorinated polyimide. CONSTITUTION: A gas sensor utilizing a thin film type fluorinated polyimide light waveguide 2 is placed in a box 7 held to an SO2 atmosphere to be detected. The laser beam from a light source 5 is inputted to the waveguide 2 through an optical fiber 3 and the output quantity of beam is detected by a photodetector 6. Herein, the light waveguide utilizing polyimide is easy to adsorb gas as compared with a usual polymer because of the polarity of polyimide and can detect gas with high sensitivity and is also excellent in heat resistance. Further, fluorinated polyimide is low in moisture absorbability. Therefore, the waveguide is easy to adsorb gas because of polyarity and can detect gas with high sensitivity because the change of light transmissivity by the absorption of humidity is not generated under usual environment.  The waveguide can remove gas by the high temp. heating of a heater 10 because of excellent heat resistance and can be repeatedly used within a short time.
