Title: Laser marking method to thermosetting resin body
Inventor: SATO OSAMU
IPC: B41M5/00
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a sharp marking, by a method wherein, after the surface of a resin body made of a set liquid resin is ground for the removal of an unset layer, a laser light is selectively irradiated on the surface of the resin body to change it in properties for marking. CONSTITUTION:A black liquid resin composition is coated on the surface of a transfer molded resin body 1 to be set. A black thermoset resin body 2 consists of an unset layer 4 produced due to either the evaporation or the deterioration by moisture absorption of a curing agent in a process of curing and a set layer 3 inside which is completely cured. The unset surface layer 4 is removed by grounding, whereby the completely set layer 3 inside is exposed to the surface. A laser light is irradiated from a laser marking equipment to the surface of the completely set black layer 3 to perform marking. The laser- light irradiation causes a pigment contained in the set layer 3 corresponding to characters to be oxidized or decomposed, thus turning the appropriate black set layer 3 into a white modified layer 5. In this manner, the good contrast between the laser-light irradiated portion and the unirradiated portion is generated, thus resulting in a sharp marking.

Title: Magnetic-tape recording and reproducing apparatus
Inventor: SUMIKAMA MASAHIKO
IPC: G11B15/43
Filed: 1988-12-07
Abstract: PURPOSE:To eliminate counter torque produced by a current caused by a counter electromotive force by respectively connecting diodes for preventing said counter current generated from a three-phase motor between respective windings of said three-phase motor and respective driving transistors for supplying each of said windings with driving current. CONSTITUTION:Hall elements Hu, Hv, Hw detect certain rotational positions of a rotor magnet to turn ON transistors Q2, Q4. Electric current from a driving power terminal Vc flows to earth via a transistor Q4, armature windings U, V, diode D5 and transistor Q2, so that anticlockwise rotational magnetic force for back tension is generated in said windings U, V. On the other hand, a supply reel 1 side motor is rotated clockwise by a tape 4 wound on a take-up reel 2. Then, counter electromotive force is generated in respective windings U, V, W and a current would flow through diodes D1-D3. However, said current is prevented from flowing by diodes D4-D6 directed in opposition to said diodes, so that torque caused by the current is not generated, too.

IPC: H01R13/64
Filed: 1988-12-09
Abstract: PURPOSE:To provide a reliable guide to engagement and prevent displacement of a pin due to difference in thermal expansion by making a member freely move because it is unlocked after it is fixed and engaged such that it can meet the position of an insertion port in a disengagement condition of a contactor. CONSTITUTION:A member 2 equipped with a guide hole 9 has its position fixed by a lock pin 7 pushed up by a spring 8 before a module pin 4 of a module 3 is fitted to a socket contact 6 in a connector body 1, and the position of the guide hole 9 agrees with the insertion position of the contactor 6. When the pin 4 is inserted, therefore, the guide hole 9 certainly guides the pin 4 so that the pin 4 is made to be fitted to the contact 6. Upon being fitted, a guide pin 5 pushed down a pin 7 with the result that the member 2 can freely move in a horizontal direction and moves to the right, and the contact 6 is warped to move slightly toward the right and concerrently, the pin 4 is warped; as a result, it hits against the wall surface of the guide hole 9 so that no excessive force is applied to the pin 4. Thereby, it is possible to correspond to displacement of pin caused by a thermal expansion difference between the body 1 and the module 3.
