Title: Resin sealed semiconductor device
Inventor: SAKURAI HISAHARU
IPC: H01L21/3205
Filed: 1983-03-08
Abstract: PURPOSE:To prevent a resin sealed semiconductor device from generation of the crack of a passivation film and generation of disconnection of an Al wiring, etc. by a method wherein patterns separated from a wiring pattern, and having a function to absorb stress are formed on the surface of a semiconductor pellet. CONSTITUTION:Patterns (dummy patterns) 14, 16 separated at least at a part from the pattern 15 of the function part of a wiring, etc., and having a function to absorb stress are formed on the surface of a semiconductor pellet. The whole is sealed with resin. Thereupon, stress to be applied from sealing resin generated according to the temperature change of environment, etc. is absorbed by the level difference parts of the dummy patterns consisting of the dummy Al pattern 14 and the dummy passivation film pattern 16. Accordingly, even when a crack is generated to the film pattern 16, and deformation is generated to the pattern 14, they exert no influence upon the function part.

Title: Frame synchronizing circuit
Inventor: ONISHI MASAHIKO
IPC: H04J3/06
Filed: 1994-03-09
Abstract: PURPOSE:To provide a frame synchronizing circuit which can set a step-out state after detecting a pseudo synchronizing state. CONSTITUTION:A pattern detecting circuit 1 compares the input data signal with a frame synchronization pattern based on the timing signal received from a frame counter 2 to decide the coincidence or non-coincidence between them. A synchronization protecting circuit 3 detects that the coincidence is continuously decided in the prescribed frequency by a rear protecting counter 32 and also detects that the non-coincidence is continuously decided in the prescribed frequency by a front protecting counter 31. Then a flip-flop 33 is set and reset by each detection output of both counters 31 and 32, and a synchronizing state signal is produced. Meanwhile a pseudo synchronization deciding circuit 4 outputs a pseudo synchronization detecting pulse when a prescribed time passed after no detection output of the counter 32 exists any more. Then the flip-flop 33 is reset by the pseudo synchronization detecting pulse so that the synchronizing state signal is forcibly set at a step-out level.

Abstract: PURPOSE: To make a substrate workable in a short time at a high precision, by attaching a holding material on the substrate to be worked in order to hold an auxilialy etching agent, then by subjecting the substrate to etch machining after the infiltration of the auxiliary etching agent into the substrate.  
     CONSTITUTION: A substrate 1 to be worked is formed, for example, by cutting a single LiTaO 3  crystal into a prescribed size. The substrate is polished on both sides, and a gold film 2 is formed on each side thereof as an auxiliary etching agent holding material by vacuum evaporation. Then the substrate 1 is negative electrolyzed in an aq. NaOH soln. to precipitate Na, i.e., an auxiliary etching agent, and the gold film 2 is converted to gold-amalgam film 3. The amalgam is removed by PEP method etc., leaving only the amalgam on the part to be worked. The Na component is thermally diffused into the substrate by heating the substrate in an electric furnace. After that, an electrode 5 and resist 6 are attached on a prescribed part of the substrate, then the diffused layer 4, which is exposed, is removed by etching with hot aq. hydrofluoric acid soln. The working process is completed with the removal of the separated resist 6 from the substrate.

Title: Error processing system
Inventor: OKUYAMA MAKOTO
IPC: G06F3/08
Filed: 1983-03-11
Abstract: PURPOSE:To prevent a decrease in the efficiency of service by providing the 1st recording means which records read information and the 2nd recording means which records normally sent-out information, and displaying the contents of the 2nd recording means when abnormality is detected. CONSTITUTION:A card 13 is passed between a light emitting element 1 and a photodetecting element 2 to read its information by a read instruction from a host device 11. This information is recorded in the 1st buffer 5 and also recorded in the 2nd buffer 9 at the same time, and the device 11 sends the next read instruction. If an error of the read of the card 13 occurs, the information is not transferred to the device 11 by being stopped by an AND gate 6, and an error check circuit 14 sends out an error signal. When the device 11 receives the error signal, it sends an instruction for sending out the contents of the buffer 9 and the contents are displayed on a display device 12. An operator searches for a card coincident with the contents and retries a read of only cards following the card by returning them.
