Patent JP-S6324789-A (JP)
Title: Remote controller
Inventor: HASE YUJI
IPC: H04Q9/00
Filed: 1986-07-16
Abstract: PURPOSE:To prevent a decoding circuit from generating a malfuntion by control ling the timing of a remote control signal after conversion so that the custom code of the remote control signal before conversion and the remote control signal after conversion is not coincident with time. CONSTITUTION:A remote control signal (a) light-received by the light receiving part 80 of a relay receiver is converted through a decoding part 83 and a coding part 85 to a remote control signal (b) for a TV set. Since the timing is con trolled by a timing signal from a timing control part 86 for the coding part 85, the remote control signal (b) converted to the light-received remote control signal (a) is delayed, the reader code occurs after the serial code of the signal (a). Thus, for the serial code of the signal (a) and the custom code of the signal (b), timing is deviated, therefore, both are hardly radio-interfered, the decoding circuit does not generate the malfunction and the remote control does not exe cute the non-action.

Title: Sand drain work
Inventor: MIURA HITOSHI
IPC: E02D3/10
Filed: 1984-08-13
Abstract: PURPOSE:To reduce the cost of sand drain work by a method in which non-circular sand columns are formed under soft ground and surrounded by water-permeable materials as needed. CONSTITUTION:A non-circular steel casing 3 is driven to the upper part of the lower sand layer 4 into soft ground, and sand S is packed into the casing 3.
