Title: Housing for cassette tape
Inventor: KONDO SHINICHI
IPC: G11B23/04
Filed: 1991-12-03
Abstract: PURPOSE:To prevent vibration from propagating to a magnetic tape by partially foaming synthetic resin and integrally molding as a vibration absorbing part when a cassette tape housing is molded of the synthetic resin thereby absorbing vibration propagating from the inside and the outside of tape. CONSTITUTION:Upper and lower halves 2, 3 are formed of ABS resin blended with foaming agent which is foamed at a vibration absorbing member 4 thus forming the member 4 integrally with the halves 2, 3. At the time of foaming, the ABS resin blended with foaming agent is set at a fusion resin temperature higher than normal molding temperature while the mold is set at a temperature lower than normal molding temperature. When fused resin is injection molded, foaming does not take place at a part contacting with the mold because the temperature of mold is low whereas foaming takes place at thick inside part where the temperature lowers slowly. Consequently, the member 4 can be integrally molded and the structure of the mold can be simplified as compared with conventional formation of reinforcing ribs. Furthermore, the space between inner and outer peripheral walls 21, 22 can be utilized for absorbing vibration, produced on the inside and outside of the housing, effectively on the opposite sides in front and rear of the cassette tape housing 1.

Title: Plastic member and ink-jet printer
Inventor: FUKUSHIMA MIZUE
IPC: C08J7/00
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent air bubbles from being entrapped at the maintenance work, prevent generation of residual air bubbles in a channel and eliminate discharge failures and nozzle contamination by setting at most to a specific value a forward and a backward contact angles of a plastic member used in an ink-jet printer using a water pigment-based recording liquid to the recording liquid. SOLUTION: When a water pigment-based recording liquid is used, a plastic member used in an ink-jet printer causes various problems because of a viscosity increase subsequent to the evaporation of vapor and aggregation of the pigment. Particularly, a maintenance suction operation is accompanied by the movement of a large quantity of the recording liquid and air bubbles, and in the interior of a channel, phases in each contact of liquid-gas-liquid... ... is successively move. A hydrophilicity is imparted to the plastic member by a UV-ozone treatment with the use of a specific treating liquid. The plastic member is formed of a fluororesin. A dynamic contact angle to the recording liquid is set so that a forward contact angle is not larger than 50 deg., and a backward contact angle is not larger than 20 deg.. Problems of mixture of air bubbles remaining inside the channel are eliminated.

IPC: H04L7/08
Filed: 1994-12-21
Abstract: PURPOSE: To decide lead/lag in a short time while reducing a circuit scale by deciding the lead/lag of inter-channel phase through the comparison of a frame number when two or more channels are used to send data. CONSTITUTION: A phase decision reference output circuit 2 provides an output of a phase decision reference value A. A frame number output circuit 4 outputs a frame number M of a frame received via a 1st channel and a frame number N of a frame received via a 2nd channel. A 1st circuit 6 outputs an absolute value D of a reference value A-number N and a code signal of the absolute value D. A 2nd circuit 8 obtains a frame number M + absolute value D = correction value P when the sign of the absolute value D indicates a positive value and outputs a frame number M-absolute value D = correction value P when the sign of the absolute value D indicates a negative value.  A decision circuit 10 decides that a frame of the 1st channel is advanced in the case of correction value P > reference value A and that a frame of the 2nd channel is advanced in the case of correction value P < reference value A.

The ion-implanted region is activated at a temperature of about 800 deg.C, and B<+> ion diffuses a little in the lateral direction to form a diffusion region 2b. When, in this state, silicon is subjected to selective epitaxial growth at about 800 deg.C, silicon single crystal (epi) 7 is grown only on a silicon part 2b (source/drain part), and, at the same time, B<+> ion creeps upward.

Filed: 1994-12-22
Abstract: PURPOSE:To elongate life of a ball bearing by scatteringly forming needle-like minute recessions on a surface of a ball for the ball bearing in random, and specifying length, width, number of the recession and center line mean roughness of the ball. CONSTITUTION:A number of needle-like minute recessions 5 are formed on a surface 2a of a ball 2 for a thrust ball bearing in random. The recession 5 has length ranging between 2.0 and 30mum, and width ranging between 0.3 and 2.0mum. The number is one to fifteen per 100mum<2>. Center line mean roughness of the ball is 0.0057mum to 0.012mum. In order to improve oil film thickness, the recession having minute length and width is suitable in addition to its roughness. This is because the oil film is effectively formed when micro EHL effect is shown at a number of positions. Oil film forming performance is improved in minute areas of a contact part between rolling elements, and metal contact ratio is lowered under a boundary lubricating condition to elongate life of the ball bearing.
