Title: Manufacture of thick film circuit substrate
Inventor: KUMAGAI KOICHI
IPC: H05K1/03
Filed: 1989-08-31
Abstract: PURPOSE:To form a fine pattern without photomask and to obtain a thick film circuit having excellent electric characteristics by drying a paste film coated with thick film paste, then irradiating it with a laser beam, removing the paste film of its irradiated part by evaporating to form a pattern film, and then baking it. CONSTITUTION:A ceramic substrate 1 is coated with thick film paste 2. Its coating method includes, for example, a screen printing method, a dipping method, etc. Then, a dry paste film is irradiated along a desired pattern with a laser beam 7, and the beam irradiated part is removed by thermally depositing to form a pattern film. In this case, air or inert gas is blown off from a blow-off nozzle 8 to blow off generated powder dusts or the dusts are removed by sucking with a suction nozzle 9 to prevent the dusts from adhering to a laser removed part. Then, the substrate formed with the pattern film is inserted into a baking furnace 1, baked, dipped in etchant solution 14, and cleaned to obtain a pattern having high insulation.

IPC: B65D85/38
Filed: 1989-09-01
Abstract: PURPOSE:To prevent impairment of the terminals incidental to the mounting and demounting of an IC package and enable mounting and demounting in a simple manner by forming both in the obverse side and in the reverse side grooves on the line connecting points substantially forming the centers of two opposed sides of all the four sides placed opposite to an IC package when it is held in place and by bending the protective case as a whole with the grooves as the crest of the bend. CONSTITUTION:Both in the obverse side and in the reverse side of a protective case 10, V-shaped grooves 14 are formed on the line connecting points substantially forming the centers of two opposed sides (for example, 102 and 104) of all the four sides (101 - 104) that are placed opposite to an IC package 2 when it is held in place. To mount an IC package on a case 10, the case 10 is held at two sides and bent to an angle with the grooves 14 as the crest. In mounting and demounting an IC package 2 on and from a protective case, a case 10 provided according to this constitution simply requires bending for the work and, without the need to use a jig or the like, simplifies the work of setting the IC package in place or displacing it. This constitution also frees the work of the possibility of impairing the terminals 6 of an IC package 2.

Abstract: PROBLEM TO BE SOLVED: To shorten the instruction fetch time by writing data into a memory via a write buffer in a data write mode and then reading the contents of the write buffer without writing any data into the memory when an instruction is fetched. SOLUTION: When a write request is given to a main storage 80 from a CPU 1, a write buffer 100 receives the write address/data and writes them into an address register 14 and a data register 15 and also starts to write these data into the storage 80. When an instruction fetch request is given to the storage 80 from the CPU 1, a control circuit 7 receives a read request signal 73 and a signal 71 showing the read contents and stores a read address in an address register 24 of a read buffer 300. If the signal 71 shows the instruction fetch (priority of read), a read operation is started regardless of the state of the buffer 100.
