Abstract: PURPOSE:To have accurate timing for changing-over and prevent contacts from being rough, by preventing generation of vibration noises at No.1 contact spring, an intermediate contact spring, and No.2 contact spring when the contact is to be changed over, and by maintaining high the contacting speeds of the contact points of these contact springs. CONSTITUTION:When a cam 3 rotates, No.1 cam surface 11 and an intermediate cam surface 12 bear No.1 contact spring 16 and a common contact spring 17 to allow them to approach to each other, and a No.1 contact 16a and a common contact 17a come in contact with each other. The intermediate cam surface 12 and No.2 cam surface 13 bear the common contact spring 17 and No.2 contact spring 18 to permit them to approach to each other, and the common contact 17a and No.2 contact 18a come in contact with each other. This reduces vibration noises likely to occur when the contacts are changed over, and relative contacting speed between the No.1 contact 16a and common contact 17a and the one between the common contact 17a and No.2 contact 18a can be increased. This accomplishes accurate timing for change over of contacts and lessens roughness on the contacts.

Filed: 1978-11-21
Abstract: PURPOSE: To shorten the time of turn-around until this device is offerred to customers, by forming this memory cell so that writing be performed after a process of manufacture of the cell is completed.  
     CONSTITUTION: A resist film is used as a mask in order to make up an impurity layer 5', but the impurities themselves are injected through a gate electrode 6'. Thus, when a ROM is kept in custody under a condition that the ROM is finished before writing and orders are accepted from customers, writing by the injection of impurities is carried out, and assembly can instantaneously be started. Writing by the injection of ions is facilitated through the gate electrode by thinning the gate electrode in a very large scale integration.
