Title: Semiconductor device
Inventor: NISHIUCHI TAIJI
IPC: H01L23/50
Filed: 1987-04-03
Abstract: PURPOSE:To prevent concentration to a die pad edge of sealing-resin internal stress due to thermal stress at the time of the packaging of a substrate by forming the shape of a die pad, with which a semiconductor chip is bonded, to a corrugated shape. CONSTITUTION:A semiconductor chip 1 is fixed onto a die pad 2 formed to a corrugated shape with adhesives. Consequently, internal stress in a sealing resin against thermal stress at the time of the packaging of a substrate for a semiconductor device is dispersed by forming the die pad 2 to the corrugated shape, thus shaping structure in which internal stress does not concentrate to the edge of the die pad 2. Accordingly, the cracking of the resin can be prevented.

Inventor: TANAKA AKIKO
IPC: H04N5/7826
Filed: 1989-03-31
Abstract: PURPOSE:To shorten the time until a drum under reproducing becomes its regular rotational phase and the time until a reproducing screen becomes stable by providing a means for forcibly resetting a quartz oscillatory reference signal in synchronization with the rise of a drum - flip flop signal (D-FF signal). CONSTITUTION:A drum FG signal is divided to produce a drum rotating speed detecting signal by a drum FG dividing circuit 5, and a drum speed system reference signal is compared to the drum rotating speed detecting signal by a drum speed comparing circuit 6. After the drum rotating speed is confirmed to be the regular rotating speed by a drum speed confirming circuit 8, the compulsory reset is made by a drum phase system reference signal reset circuit 4 in synchronization of the rise of the quartz oscillatory reference signal 11 with the rise of the D-FF signal 12. When the quartz oscillatory reference signal coincides with the D-FF signal in rising phase, the drum becomes its regular rotational phase, so that simultaneously with the reset, the phase becomes the regular rotational phase, and the rotation of the drum is stabilized so as to become under the regular reproducing state. By this method, the time until the drum under reproducing becomes the regular rotational phase and the time until the reproducing becomes stable both are shortened.

IPC: H04M3/48
Filed: 1985-04-18
Abstract: PURPOSE:To attain automatic camp-on setting by calling a calling subscriber after a called subscriber when this called subscriber is idle in case a specific subscriber is called. CONSTITUTION:A front 3 picks up a telephone receiver and calls a calling subscriber 1 registered by the call signal IR out of a call signal unit RGU and hears the ringing tones given from a tone generating unit TGU. Then the talking is possible with an answer given from the calling subscriber. In case plural calls are given to the front 3 which is under a busy mode, these calls are registered successively to a camp-on setting memory CMEM and undergo the arriving order processing. Thus the camp-on service is possible even to an ordinary guest who is unfamiliar with the dialing operation for telephone service.
