Title: Resin molded product due to contraction flow and molding thereof
Inventor: KUMAGAI YUKIHISA
IPC: B29C45/37
Filed: 1994-11-18
Abstract: PURPOSE: To enhance tensile and bending breaking strength to stabilize quality by utilizing fiber-containing effect by generating contraction flow in a root part ready to be structurally reinforced in a resin flow direction to largely change the orientation of a fiber in the contraction flow part. CONSTITUTION: In an injection process of a columnar test piece, when a product part cavity is filled with a molten resin from the gate 3 of the region 4B corresponding to a thick-walled part, the fiber in the molten resin at the root part 4C of the thin-walled part 4A continuing to the thick-walled part 4B is strongly oriented in a resin flow direction by the contraction flow shown by an arrow from the thick-walled part 4B to the thin-walled part 4A. When the wt. average fiber length in the molten resin is large, this tendency becomes marked and the strength against load is enhanced. Contrarily, when the product part cavity is filled with the molten resin from the gate 3 of the region A of the thin-walled part and the resin flows so as to expand from the thin-walled part 4A to the thick-walled part 4B, the fiber in the molten resin at the root part 4C of the thick-walled part 4B is strongly oriented in the direction right-angled to flow and, therefore, the fiber becomes orientation disadvantageous against load.

Filed: 1992-10-02
Abstract: PURPOSE:To make the information pattern, which is formed by the partial removal of a metal vapor deposition layer, readable even when the pattern is covered with the stain of the printed surface of a magnetic card and an invisible layer by treating the detection signal which is detected by scanning of a sensor head. CONSTITUTION:By printing with a thermosensible recording head contacted on a magnetic card from the surface of a protective layer 5 according to a usual thermosensible recording method, three removal parts 3B1, 3B2, 3B3 are formed which change within the range of a width of about 5mm and a length of 5-10mm. The part excluding the removal parts is a non-removal part 3A. Scanning with a sensor head S being moved at a constant speed of 20mm/ sec is carried out to keep a constant space of about 0.1mm between the surface of the magnetic card and the tip of the sensor head S. The output voltage obtained at the removal parts 3B1, 3B2, 3B3 which is formed on a metal deposition layer 3 is sufficiently higher than the output voltage obtained at the non- removal part 3A, thereby producing a voltage difference of about 1V. Accordingly, information reading can be conducted in a non contact method to attain high reading reliability.

Filed: 1986-12-02
Abstract: PURPOSE:To decode a Manchester code even without using a preamble by detecting the pause of a bit in the Manchester code by means of '11' or '00', and latching the second half or the first half of the bit in accordance with the detected pause. CONSTITUTION:A synchronizing part 101 obtains the synchronization with the system clock which is four times a data in frequency for an input Manchester code. A bit pause detecting means 102 detects the pause of the bit with '11' or '00' in the Manchester code for which the above-mentioned synchronization is obtained. A latch clock generating means 103 generates a latch clock corresponding to the second halt or the first half of the bit in accordance with the pause of the detected bit. The latch clock is the clock which is two times the data in frequency. A decoding part 104 decodes the data by latching the second half or the first half of the bit with a latch clock. For this reason, without using a preamble, the Manchester code can be decoded.
