Title: Lead processing machine
Inventor: OBA YOSHIHARU
IPC: H01L23/50
Filed: 1988-03-03
Abstract: PURPOSE:Not to deteriorate the quality of a product by providing a resin burr removing punch made of hard rubber having an end of width wider than the interval of leads of an IC to be processed. CONSTITUTION:A resin burr removing punch 6 made of hard rubber such as urethane rubber having an end face of wider width than the interval D of leads 7 of an IC 8 to be processed to be elevationally movable and inclined is provided at recesses formed on the side face and bottom of an upper block 1 as guides oppositely between the leads 7 positioned on a lower block 10. Since residual resin burr pieces 9 adhered between the leads 7 of the IC to be processed can be forcibly removed by the punch 6 before a bending roller 3 moves down, it can prevent the pieces 9 from being press-bonded to the leads 7. Thus, it can prevent the plated faces of the leads 7 from damaging and plating from peeling off.

Title: Optical disc device
Inventor: HAYASHI SHINICHI
IPC: G11B7/013
Filed: 1982-03-31
Abstract: PURPOSE:To improve recording density, by measuring the run length of 1 or the like or 8-position symbols combined with 4-bit data and compensating the interwave interference of at the boundary of the symbols. CONSTITUTION:The 8-position symbols recorded on an optical disc are formed with 4-bit data including a 1 in such a way that an odd number of 0s are continuous. In some cases, one 0 at the boundary where the symbols are connected is erroneously read as 1 on account of interference. The symbols are applied to a run length circuit 53. A setting circuit 54 for set conditions responds to the runn length of the 1st 1 and a setting circuit 55 for reset conditions responds to the run length of the 2nd 1. The clocks between the set and reset are counted with a circuit 56, and the run length of the set signal and the reset signal that may be made into a digital value by the 0 at the boundary and the length of both signal is determined. Therefore, if the output of an oridinary decoder 51 and the decoded output when the interference arises are selectively outputted with a change-over circuit 50, the interwave interference is compensated substantially, the need for increasing the interbit spacing for the purpose of preventing interference is eliminated and the recording density is improved.

CONSTITUTION:A plywood 1 consists in compression-molding wood fibers in such a shape that the top surface provides with grooves 3 in the predetermined pattern and the underside provides with grooves 6, each of which is formed at the portion corresponding to the flat made between the grooves 3 on the top surface. Heat radiating bodies 3 are provided so as to be housed in the grooves 2 open on the top surface of the plywood 1. A panel type heater consists on attaching a heat insulating plate 4 onto the underside and a soaking plate 5 is provided onto the top surface of said plywood 1 equipped with the heat radiating bodies 3 in the grooves 2. Consequently, because all the depth of the grooves 2 on the top surface of the compression-molded plywood 1 are constant, the heat released from the heat radiating bodies 3 provided by being housed in the grooves 2 can be uniformly dissipated from the whole surface of the soaking plate 5 into a room. In addition, because the heat insulating plate 4 is attached onto the underside of the plywood 1, the heat loss, which dissipates outside the room, is extremely small, resulting in enabling to uniformly and efficiently heat the whole interior of the room. Further, because hollow spaces, which are formed by the grooves 6 on the underside, are provided on both sides of each groove 2, in which the heat radiating body is housed, the excellent heat insulation effectiveness and at the same time the lightening of the whole weight of the heater are realized.
