Title: Manufacture of flexible rigid wiring board
Inventor: NISHIMURA YOSHIO
IPC: B32B15/08
Filed: 1991-10-02
Abstract: PURPOSE:To reduce dimensional shrinkages of a flexible board by eliminating residual stress, resulting from manufacturing processes of the board, by means of heating processes. CONSTITUTION:A conductive foil 2 used for forming a circuit pattern 6 is laid over a flexible board 5, and the laminated structure is then wrapped in a coil with the conductive foil 2 side thereof being enclosed, wherein the diameter of the coil is in a range of 25mm-50mm. The coiled board is then subjected to heating processes at a temperature of 100-200 deg.C for half an hour - three hours. Heating processes with a much lower temperature do not effectively cause residual stress to be eliminated, whilst the heating processes with a much higher temperature causes a base material of a film and an epoxy adhesive to be thermally deteriorated. Therefore, the temperature of the heating processes is strictly limited to the range of 100-200 deg.C. Thereby, the residual stress accumulated in the flexible board 5 is eliminated, and hence thermal shrinkages of the board can be reduced.

Title: Electric field input stop mechanism for probe for surface potential measurement
Inventor: KINOSHITA KENJI
IPC: G01R29/12
Filed: 1988-10-11
Abstract: PURPOSE:To reduce the cost by fitting a conductive shield late which is provided with an opening part to an equipment body and thus stopping down an object part of detection to desired size. CONSTITUTION:The probe 5 is put close to the object 9 of measurement and its surface is set opposite the opening part 6.

Title: Magnetic recording and reproducing device
Inventor: FUJII TOSHIFUMI
IPC: H04N5/783
Filed: 1985-11-13
Abstract: PURPOSE:To perform high speed reproduction without noise by reading out a reproducing signal stored at a storage circuit, and deriving it as a reproducing information signal in a period other than the write period of a head reproducing signal on the storage circuit. CONSTITUTION:When a high speed reproduction indicating signal SS becomes 'H', a high speed travelling is generated synchronized with the trailing edge of a head switching signal HSW, and during the period of the high speed travelling, a signal stored at a digital memory 7 in a normal reproduction performed just before is read out. Also, during the high speed travelling period, the number of pulses of a control signal CTL is counted at a timing signal generating circuit 16, and at a time when it arrives at a prescribed value, the travelling of a tape is terminated, and the signal stored at a magnetic tape 29 is reproduced, then being stored on the memory 7. If the signal SS is remained as the 'H' at a time to move to a write, a high speed travelling state is generated again after the storage of the signal, and such operation is repeated. If the signal SS is at 'L' at the time to move to write, the input of a motor driving circuit 24 is switched to the output of a travel control circuit 23, and a state enters in a normal reproduction state after a static state. Therefore, the high speed reproduction without the noise can be performed.
