Patent JP-H0195589-A (JP)
Title: Attachment structure of leadless component
Inventor: TAKIGAMI KOTARO
IPC: H05K1/11
Filed: 1987-10-07
Abstract: PURPOSE:To make it possible to obtain the self alignment effect by soldering by making the width of the round parts of the conductor layer wider than the width of the electrodes, and making the width of the lead parts of the conductor layer narrower than the width of the electrodes. CONSTITUTION:The width of the round parts 4a formed oppositely to each other on an insulating substrate 1 and contributing to the soldering of a conductor layer 4 is formed wider than the width of the electrodes 3 formed on both end parts of a circuit component having no lead wire 4b. Also, in the part extending from the round parts 4a to the exterior of the circuit component, the width of the lead parts 4b of the conductor layer 4 where solder fillets 5 are to be formed is made narrower than the width of the electrodes 3. Accordingly, when an external force acts on the insulating substrate, the distortion of the insulating substrate due to this is absorbed by the solder in the lead parts. With this, the occurrence of cracks to a leadless part can be prevented, whereby the self alignment effect at the soldering time can be obtained.

Title: Telephone exchange
Inventor: NOZAKI SHUJI
IPC: H04Q3/58
Filed: 1986-10-24
Abstract: PURPOSE:To prevent an erroneous detection of a turning-off of loop caused by a polarity inversion metering pulse as a hook-off by providing a decision means to decide a hook-on detection, selecting a second hook-on detection time longer than the interrupting time of the polarity inversion metering pulses, and deciding on a hook-on at the time when an loop-off output time reaches this long hook-on detection time. CONSTITUTION:A control circuit 601 checks whether a telephone is busy with incoming-call-speaking or not by means of the content of a speaking status memory, if it is not busy, further checks whether the setting by a setting switch 611 shows the presence of a catch-phone service or not. In case of checking results in the present of catch-phone service, whether or not the loop-off continues for 0.2sec is checked by means of the counting of a counter, when it continues for 0.2sec, a hook-on is registered in a hook status memory. On the other hand, in case of setting in non-catch-phone service, a hook-on is registered after the loop-off continues for one sec. Consequently, within providing a means to set the presence absence of metering service otherwise, an erroneous detection at the time of chargeable service can be prevented.
