IPC: H01L23/50
Filed: 1992-10-07
Abstract: PURPOSE:To provide a wire bonding method for realizing cost reduction and enhancement of productivity while shortening the bonding time in an interconnection bonding system. CONSTITUTION:Wiring bonding is performed using an electrode pad 2 on an IC chip 1 mounted on a resin(insulator) board 3 as a first electrode, an interconnecting point 4 on the board 3 as a second electrode, and an inner lead 5 as a third electrode thus interconnecting the electrode pad 2 and the inner lead 5 to be conducted. After performing ball bonding on the electrode pad 2, stitch bonding is performed without cutting a wire 7 at the interconnecting point 4 and then the wire 7 is brought, while making a loop, to the inner lead 5 where stitch bonding is performed and the wire 7 is cut off. When a groove is made at the interconnecting point 4, external bonding force is increased and quality can be sustained between steps.

Abstract: PURPOSE: To prevent a recording paper from being wet in black with ink and being twisted by dividing picture elements arranged at ink jet recording into windows of a prescribed number and converting part of black picture elements in the windows arranged under a prescribed condition into white picture elements. CONSTITUTION: A picture element position control circuit 22 outputs a request signal of image data by a required number of lines for picture element processing to a CPU. The CPU transfers data in an image memory 6 to a line memory 20. Then, the circuit 22 gives 3×3 picture element data from the memory 20 to an arithmetic section 21 and conducts image processing to convert black picture elements in the middle of the 3×3 window into white picture elements depending on the arithmetic operation result of a prescribed arithmetic expression. The data subjected to image processing are fed to a buffer in a recording section 15. Succeedingly, the circuit 22 applies similar processing to windows shifted by three columns and repeats it to process all picture elements.  Since the number of dots are interleaved more than those of the image recorded usually, the amount of ink and the power are saved.

Title: Light coupling structure
Inventor: YAMAGUCHI SHUICHIRO
IPC: H01L31/12
Filed: 1987-10-27
Abstract: PURPOSE:To simplify a mounting process and improve photo transmission efficiency as well, by making the light receiving plane of a photodetector face to a light emitting element in the structure of light coupling which is composed by mounting elements of light emitting and photodetector on the same plane. CONSTITUTION:A light coming from a light emitting element 1 performs direct irradiation to the light receiving plane 2a of a photodetector 2. As the light emitting element 1 emits light from a horizontal direction, the same photo transmission efficiency as a conventional one can be obtained. Further, as the light emitting element 1 and the photodetector 2 are mounted at the same plane, its mounting process is simple as well and it can be carried out at a low cost. Moreover, the light receiving plane 2a of the photodetector 2 and the plane equipped with elements are perpendicular to their mounting planes that no wire bonding is possible. Then, an electrode 6 is extended up to a mounting end plane of the light receiving plane 2a at the photodetector 2 to perform electrical connection between the electrode and the mounting plane by connecting directly the electrode to the mounting plane so that the foregoing difficulty regarding wire bonding can be overcome.

Abstract: PURPOSE:To conduct most suitable defrosting operation in accordance with the state of frost formation on an outdoor heat exchanger by providing a temperature sensor which detects temperature change in an indoor heat exchanger, a frost formation sensing circuit, and a timer circuit which changes the setting of time for defrosting operation. CONSTITUTION:The input side of a microcomputer is provided with a thermistor 7 for temperature sensing via a comparator 8 and a setting resistor 13 for a set temperature difference DELTAT. The microcomputer 9 incorporates a memory 10 which stores the temperature Ts of an indoor heat exchanger at the time of starting defrosting operation and an arithmetic unit 12 which compares a set temperature difference with the temperature difference Ts-Td which is the temperature Ts minus Td, the temperature of an indoor heat exchanger at the time when a certain time has passed after starting the defrosting operation and conducts change-over of set defrosting operation time in a timer 11. A temperature difference DELTAT between a temperature Td after a certain time N1 has elapsed and the temperature Ts is taken and it is compared with temperature T1 set beforehand. If this temperature difference DELTAT is higher than T1, a shorter defrosting time N2 is used. On the contrary if DELTAT is lower than T1, a longer defrosting time N3 is used, and it is possible to carry out defrosting operation most suitable for the state of frost formation.
