Title: Watch for the blind
Inventor: FUJITA MASANORI
IPC: G04G13/00
Filed: 1981-12-24
Abstract: PURPOSE:To have an alarm every minute and to prevent a time shift due to a finger touch, by using a minute switch of a prescribed unit of >=5min and four hour switches and then producing an alarm sound when the switch corresponding to the present time is operated. CONSTITUTION:For instance, the present time shows 8:12. Then an hour switch is pushed to secure the coincidence between the output of an encoder EH and the output of a time counting circuit HT2. As a result, an output is produced from a coincidence circuit CN3, and an alarm sound of 6:00 is produced from a sound producer SP with every 3hr. When the alarm is over, a control circuit B2 operates. A time counting circuit HA1 is counting a fraction 2 of hour, and therefore the alarm sound is produced twice from the producer SP to inform 8:00. Then a minute switch is pushed to secure the coincidence between the output of an encoder EM and the output of a time counting circuit MT2. Then an alarm sound is produced from the producer SP to inform the time every 10min. A time counting circuit MT1 is counting 2min, and the different alarm sounds are produced twice from the SP to confirm 12min with a pulse supplied from a control circuit B1 when the alarm is over.

Title: Ic card
Inventor: MUNAI SHIGEHARU
IPC: G06K19/077
Filed: 1984-10-17
Abstract: PURPOSE:To obtain an IC card having no bad influence to an IC chip by concentrating a generated stress at a section having a low hardness provided at a position separate from the IC chip when the IC card received an external force. CONSTITUTION:A reinforcing plate 2 is disposed directly below an IC chip 3 mounted on a chip mounting base plate 4 in a card body 1. Accordingly, the section on which the reinforcing plate 2 is disposed has a larger bending stress resistance than other sections. When an external force to fold and bent the card is applied, since a section having no reinforcing plate 2 is folded and bent, a break of the IC chip 3 can be prevented without applying the stress to the IC chip 3. When a bending is concentrated to a section on which the reinforcing plate 2 is not disposed and there is a danger that a wiring of the chip mounting base plate is broken, it can be easily avoided by using a base plate having a complete bending stress such as an EPC base plate as a base plate material.
