Filed: 1980-12-25
Abstract: PURPOSE:To increase a protective effect for a chip and prevent a short-circuit of lead frame by attaching and forming an insulated organism layer onto an active region and a dicing region of a chip having a projecting electrode mounted thereon. CONSTITUTION:For example, a polyimide resin film 6 is attached to the entire surface of a wafer 5 having a projecting electrode 3 mounted thereon through a barrier metallic layer 2 and a resist mask 8 is provided on a region covering the active region and a dicing region line 4 of a chip 9.

Title: D/a converter
Inventor: SHIBATA TAKAYASU
IPC: H03M1/78
Filed: 1988-07-25
Abstract: PURPOSE:To prevent a change in an output voltage even if a resistance value of a reference voltage resistor is changed due to a linear gradation of injection concentration in the process by providing a circuit extracting a differential voltage from a resistor for producing a reference voltage and a subtraction circuit. CONSTITUTION:With a positive voltage applied to a positive voltage input terminal 18 and with a negative voltage applied to a negative voltage input terminal 19, voltages divided by resistors 1, 2, 3 and 4 appear across the resistor. Then a control signal to obtain a required voltage is fed to switches placed at an equal distance from the terminals 18 and 19 (applied in pairs of switches 13 and 17, 14 and 16, and 15a and 15b). Then the switched and selected positive voltage is applied to a positive input terminal 22 of a voltage substraction circuit 21 and the switched and selected negative voltage is applied to a negative input terminal 23 and the voltages are subtracted with each other and outputted. In such a case, the circuit 21 is operated so that the voltage at a voltage output terminal 20 is equal to a voltage decreasing the voltage at the terminal 23 from the voltage at the terminal 22. Thus, even if the reference voltage resistance is varied due to the linear gradation of the injected concentration in the process, the output voltage change is prevented and the degree of freedom of the circuit design or the like is enlarged.

Title: Monoroom type continuous hot press
Inventor: KOIDE HIROSHI
IPC: F27B17/00
Filed: 1994-07-14
Abstract: PURPOSE:To bring the temperature of each part in a furnace into a desired temperature pattern by a method wherein intermediate doors are arranged in front of a preheat part and in the rear of a postheat part to form a furnace body, and intermediate dampers for heat insulation released to an extent high enough to prevent impedance of transfer of a molding die in a furnace body are disposed in front and in the rear of a press part. CONSTITUTION:Movement is practicable in such a way that a continuous hot press completes one cycle and an intermediate damper 1 on the charge side is moved backward to a position to prevent interference with a mold die located in a tray 44 through the working of an air cylinder 6. When transfer of the tray 44 is completed, the intermediate damper is moved forward through the working of the air cylinder 6 to close the traverse surface of a furnace. Since intermediate dampers 1 and 11 formed of a carbon fiber-reinforced carbon composition material insulate heat and also have reflection action, through individual control of a heater arranged at each part, production of a temperature difference between the temperature of a press part B in a furnace and those of a preheat part A and a postheat part C arranged in the front and at the rear thereof is practicable. This constitution provides the degree of freedom of a heat history exerted on a material throughout temperature control during press and front and rear processes.

Title: Assignment request multiple access communication system
Inventor: TAKAHASHI TSUKASA
IPC: H04J3/00
Filed: 1984-09-05
Abstract: PURPOSE:To attain effective use of power of a satellite repeater by allowing a central processing unit to store in advance a value of a reception performance figure G/T of each earth station, managing the value in total, transmitting the size of each opposite station antenna as data and allowing the received station to transmit data with a designated power. CONSTITUTION:Performance data of each earth station is changed easily by managing it at a master station to make the line quality constant at all times. For example, when a line assignment request takes place in a calling station, a CSC line 13 is used and a request signal is transmitted to the master station. The master station uses the CSC line to inform the line number and the size of an opposite station antenna to a calling station. A control processor 13 of the calling station analyzes this signal and uses a transmission power controller 12 to apply the signal level outputted from a terminal station 11 as the designated power. Thus, the change is made easily and sure line quality is obtained, and when a station not scheduled for line acquisition such as a mobile station is in operation, the communication line is set easily by registration and erasure to/from the central station.

IPC: A61B5/055
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To restrain image blurring artifacts resulting from signal strength differences and swells even in the case of totalizing image pickup using grase method. SOLUTION: In a former pulse sequence, a group of spin echo signals is placed in a low-frequency range while a group of gradient echo signals is placed in a high-frequency range. In the next pulse sequence, a group of echo signals in each group is inverted with respect to the center of phase encoding direction in each group in the former pulse sequence. When they are totalized, the echo signals S1, S7 having maximum and minimum signal strengths, respectively, are totalized and echo signals S4 of the same signal strength are totalized. Therefore, signal strength differences ΔS5, ΔS6 can be reduced and the profile of the signal strengths can be smoothened.
