Title: Lighting system
Inventor: MASUDA NAOKI
IPC: H01J61/52
Filed: 1994-10-13
Abstract: PURPOSE: To provide a lighting system which always excels in color rendering in an arbitrary installation direction and has a long life. CONSTITUTION: A lamp 1 is fitted on a base 2 and the base 2 is fitted on a reflecting mirror by a spacer 3. A bearing 6 fitted on a wind shielding body 5 is fixed to the reflecting mirror 4 by a fitting piece 7. The wind shielding body 5 on which the bearing 6 is fitted has a weight 11 and is slid in the direction of gravity to shield a ventilating hole 10 in the lower part of the space 3. The wind passing through the ventilating hole 10 of the opened upper part positively cools the upper part of the lamp 1.  Thereby, the temperature of the upper part is greatly lowered without lowering the temperature of the lower part of the lamp lit up in the arbitrary direction to reduce a temperature difference between the upper part and the lower part of the lamp, thereby preventing the deformation such as the expansion of the upper part of the lamp, so that the long life may be achieved and the color rendering my be enhanced.

Filed: 1984-11-26
Abstract: PURPOSE:To permit F.I.T element to perform a field accumulative operation without lowering sensitivity by transferring a signal charge of light diode of odd number (even number) in the first half of perpendicular blanking period or by transferring a signal charge of light diode of even number (odd number) in the later half of perpendicular blanking period after setting up plural accumulation areas through perpendicular CCD to respective accumulative portion. CONSTITUTION:Once a light is irradiated at the shadowed portion of a photoelectric transfer portion 21-3, charges of A, B, C, D are accumulated at light diodes of this portion. The charge A and C on the odd line are read out to a direction of CCD20-3 for a vertical transfer for a period of 50. Its charge read out to CCD for the vertical transfer is transferred to the accumulative portion on the odd row through a coupled portion 30-3 in a period of 51. In a period of 52, charges B and D on the even line are read out to the direction of CCD20-3 for vertical transfer. In like manner, in a period of 53, charges read out to CCD for vertical transfer are transferred to the accumulative portion on the even row through the coupled portion 30-3. At this time a transfer to the accumulative CCD on the odd row is held back. Charges at the accumulated portions in the period on the odd row are transferred by CCD23 on the upper level and charges at the accumulated portions in the video period on the even row are by CCD24.

Title: Mobile radio communication equipment
Inventor: HIGA TETSUYA
IPC: H04B1/3822
Filed: 1990-09-18
Abstract: PURPOSE:To make the improvement of a radio characteristic compatible with the improvement of economy by providing a detection means to detect an operating period of a frequency synthesizer and a power supply voltage control means in addition to a voltage conversion circuit boosting the output voltage of a battery to generate a power supply voltage to the communication equipment. CONSTITUTION:When a frequency synthesizer 21 is in operation, a 1st power supply voltage VUP1 stabilized into a constant voltage by a constant voltage circuit resulting from consecutive clocks and employing a Zener diode ZD is applied to the frequency synthesizer 21. Thus, the frequency synthesizer 21 makes oscillation without being affected by a ripple of the power supply voltage. Moreover, when the frequency synthesizer 21 is not in operation, the supply of a clock CK to a D/D converter 31 is made intermittent and a voltage lower than the power supply voltage VUP1 fed to the frequency synthesizer 21 is generated and fed to a CPU 40a. Thus, since deterioration in the radio characteristic is not caused and the power consumption is reduced, both the improvement of the radio characteristic and the improvement of the economy are made compatible.

Title: Lsi mounting structure
Inventor: KATO CHIKAYUKI
IPC: H05K3/34
Filed: 1990-09-19
Abstract: PURPOSE:To reduce the cost of an LSI mounting structure by a method wherein one end of a fine metal wire is formed into the form of a ball and thereafter, the other end of the wire is fused-cut and micropins, which are made using the metal wire and whose peripheries are covered with a solder layer, are made to align on metal pads formed on the surface of an LSI chip circuit and are connected and fixed on the pads by a solder reflow. CONSTITUTION:Bonding wires, which are used for the electrical connection between an IC chip and an IC package, are normally used for micropins 5. One end of and Au wire of a wire diameter of 20 to 50mum, for example, is formed into an Au ball using an electric torch by a mechanism like a bonder, the length of the Au wire is set into a length of 2 to 5mm or thereabouts and the other end of the Au wire is fused-cut. After that, the surfaces of the micropins made using the Au wire are covered with a solder layer 4. At the time of mounting, a special flux for Al use is applied on the surfaces of pads 6 and the pads 6 can be connected with the solder layer 4 on the surfaces of the pins 5. The pads 6 are formed into the structure of a bump consisting of a Ti-Pt-Au layer and there is also a method of erecting the pins 6 by the solder layer, but the yield of a wafer is bad and the cost of an LSI mounting structure is increased. Accordingly, it is also enough to simply apply the flux on an Al layer on the pads 6. The micropins are made to adhere to electrodes 3 on a multilayer interconnection board 7 using an eutectic solder.
