Filed: 1992-02-18
Abstract: PURPOSE:To enable the inexpensive and mass production of an extremely thin and light diffraction grating by using a stamper in producing the diffraction grating. CONSTITUTION:A diffraction grating pattern 7a is transferred to a synthetic resin, such as acryl, polycarbonate or vinyl chloride, by injection molding, etc., using the nickel stamper 60 having the rugged pattern corresponding to the above-mentioned diffraction grating pattern, by which a resin substrate 61 having the diffraction grating pattern 7a is formed. A metal, such as aluminum Al or gold Au, having a high reflectivity is deposited by evaporation on the diffraction grating pattern 7a of this resin substrate 61. An aluminum film 62 is deposited thereon in such a case and thereafter, a thin film 65 of the synthetic rein is deposited on this metallic film 62. The thin film 65 side of the substrate formed by depositing the metallic film 62 on the diffraction grating pattern 7a of the resin substrate 61, then depositing the thin film 65 thereon is adhered to a material 64 to be measured via, for example, an epoxy adhesive material 63. The resin substrate 61 is peeled after this adhesive material 63 cures.

Title: Packaging and package
Inventor: HATADA KENZOU
IPC: H05K1/18
Filed: 1980-03-11
Abstract: PURPOSE:To make a highly integrated and thin package of electronic parts by a method wherein a lead of a wiring pattern which has been insulated from the opening of a metal frame is formed in such a way that the lead is projected from the opening, and a piece of element is connected to the lead. CONSTITUTION:An opening 12 is formed in an insulating film 11. Next a Cu foil 13 is made to adhere to the opening to produce a Cu wire lead 13' projected from the opening 12 by means of the photoetching method. Then an Ni plate 14 with an opening that is almost as wide as the opening 12 is made to stick onto the film 11. This is followed by the formation of soldering bumps on the electrode terminals of a chip part 17 and an IC18 before inserting them into the opening 12 to connect the terminals of the part 17 and the IC18 to the wiring 13. The package thus formed can be made thinner because either the film 11 or the Ni plate 14 is thin. At the same time, since an area for connection becomes unnecessary on the circuit board, packaging density can be increased by that rate.

Abstract: PURPOSE:To measure precisely the time between two points accurately by switching write clock signal frequencies with a trigger signal, and measuring the time from the last 1st clock signal to the starting 2nd clock signal. CONSTITUTION:When a comparator 16 generates the trigger signal, the output of a latch circuit 28 goes up to a high level, and an electronic switch 21 supplies a high-frequency clock signal A as a write clock signal to an A/D converter 14 and an address generator 24.

When the trigger signal is generated, a terminal E of the counter 76 falls to a low level and the counter 76 stops counting operation. Then, when the time between two points including the trigger point is measured, the contents of the counter 76 are read by a CPU and the value is considred to calculate the accurate time.
