Title: Semiconductor device
Inventor: HAYASHI KAZUMI
IPC: H01L23/31
Filed: 1992-01-27
Abstract: PURPOSE:To improve the water resistance and corrosion resistance for a connecting portion between a semiconductor chip and a lead by coating the whole surface of the semiconductor chip and a surface containing an electric connection between the semiconductor chip and an external leader line with water-resistive, corrosion resistant films and further sealing them with a hard type resin forming body. CONSTITUTION:Electrical bonding between an electrode 3 of a chip and a lead frame is made by a bonding wire 5. In the water resistant coat treatment, a solution of a soft high molecular material 7 with water resistance and corrosion resistance is applied to fully cover the whole surface of a semiconductor chip 1, a bonding portion between the bonding wire 5 and lead frame 4, and especially electrode 3. Then, water resistance-treated semiconductor chip is set in forming dies, the whole of the connecting portion with the chip bonding wire is surrounded and sealed with a packaging material 6 made of a hard thermosetting resin. By doing this, the corrosion of the connection between the semiconductor chip 1 and bonding wire 5 due to ingress of water can be prevented.

Title: Ceiling panel of heat radiation type
Inventor: INANUMA MINORU
IPC: F24D13/02
Filed: 1986-01-24
Abstract: PURPOSE:To significantly shorten the rise time of temperature during which the heat radiating surface of a ceiling panel comes up to a predetermined temperature, by increasing the thermal conductivity of a heat-generating resistance wire, by fitting a metallic fin to the resistance wire, or by directly fitting the resistance wire to a heat-radiating metallic sheet. CONSTITUTION:Transmission of heat from a resistance wire 4 to a plaster board 2 is greatly increased by increasing the effective heat-radiating area of a resistance wire 4 by fitting a metallic fin 12 to the heat conductive sheathing 11 of a resistance wire 4. Accordingly the time delay from rise in temperature of the resistance wire 4 to rise in temperature of the heat-radiating surface of a plaster board 2, that is the surface opposite to the surface on which the resistance wire 4 is fixed, is greatly shortened. A heat-insulating layer 7 provided to cover the surface on which the resistance wire 4 is fixed serves to shorten the time delay by preventing heat from leaking to the opposite side of the heat-radiating surface of a plaster board 2. The time delay is further shortened, because the heat-radiating surface is made of a metallic sheet 15, on which the resistance wire 4 is directly fixed.

Title: Control circuit of electronic flash device
Inventor: HOSHI HITOSHI
IPC: H05B41/32
Filed: 1983-01-28
Abstract: PURPOSE:To realize size reduction by connecting a GTO in series with a xenon lamp, a turn-on circuit and a turn-off circuit to the gate of the GTO, and a spike voltage absorbing circuit between the anode of the GTO and high-voltage side of a main capacitor. CONSTITUTION:The main capacitor 2 and a capacitor 14 are charged by a converter 1 respectively. When a shutter button is pushed, a trigger pulse is applied to the gate of an SCR5 and the gate of the GTO 31 to turn on the both. At this time, the capacitor 14 is discharged through an SCR5 to turn on the xenon lamp 9, and a current (i) flows from the main capacitor 2 to maintain the light emission. A photodetecting circuit 24 outpus a trigger pulse when its photodetection amount attains to a specific value, and the turn-on circuit 34 leads a turn-off current from the gate of the GTO31, so that the xenon lamp 9 does not emit light any more. Further, a spike voltage VSP generated when the GTO31 turns off has its peak value suppressed by a diode 35. This system is suitable for the size reduction and protects the GTO from the spike voltage.

Abstract: PURPOSE:To eliminate a couple of coder and decoder and to efficiently use memories by providing plural line memories and a selector selecting the outputs between a couple of coder and decoder, switching picture information at every scanning line so as to execute a time division processing. CONSTITUTION:A decoder 8 reads picture information stored in a RAM2 from a disk device 5 for one scanning line, expands data, and supplies it to the line memories 10 and a coder 9. A selector 11 selects the outputs of the memories. The coder 9 collates to the output of the selector 11 as a collating line while it compresses a picture signal from a decoder 8. At the same time, the memories 10 are switched and used, and picture information is time division processed at every scanning line, and is transferred to a communication control part 12. Thus, a couple of coder and decoder provided at every circuit of a communication port is eliminated, and waste in the capacity of the memories for switching and using the memories for one scanning line is avoided.
