Abstract: PURPOSE:To obtain a writable, readable and erasable nonvolatile memory cell in a semiconductor substrate with a small occupied area by a method wherein only one high-concentration impurity region and one gate electrode, with reference to the semiconductor substrate, function as a memory cell. CONSTITUTION:An electric current flowing between a semiconductor substrate 11 and a drain region 12 is set as a tunneling current by electrons which are tunneled to a conduction band from a valence band near an interface of a gate insulating film 14 of mainly the drain 12 in a region where the region 12 and a gate electrode 15 are faced via the film 14. The tunneling current Id is changed extremely largely with reference to a vertical electric field Es. Carriers are captured by a hole trap 13 which has been formed in the film 14 of the region where the region 12 on a region generating the tunneling current is faced with the electrode 15; the electric field is changed by the carriers. A difference in a current quantity of the tunneling current which is changed largely is made to correspond to binary information, and a storage function of information is realized.

Title: Bias circuit
Inventor: SHIOMI TOMONORI
IPC: H04L25/06
Filed: 1986-10-21
Abstract: PURPOSE:To prevent the aperture efficiency of the eye parttern of a modulation signal from being deteriorated and also a transition state just after transmission begins from being generated constituting a bias circuit only with resistances and a switch and not using a capacitor which obstructs a direct current. CONSTITUTION:A titled circuit has the resistances 3-6 and the switch 7 and in case of reception the switch 7 is made in ON state so as to keep an input terminal 1 in the same electric potential as a second reference voltage terminal(earth) and meanwhile in case of transmission the switch 7 is turned OFF so as to input the modulation signal in the input terminal 1 and obtain the outputs from connection point of first and second registances 3 and 4. Thus the aperture efficiency of the eye pattern of the modulation signal inputted in a modulator 9 is not deteriorated and the transition state does not occur just after the transmission begins, since the capacitor is not used, which obstructs the direct current and causes time constant.

Filed: 1986-10-20
Abstract: PURPOSE:To block the storage of an unnecessary read data into a memory by adopting a constitution that a read data is fetched in the memory when the count of a detection pulse outputted from a moving amount detection section reaches a setting value. CONSTITUTION:When the manual sweep of an image sensor is started, a detection signal is outputted continuously from a moving amount detection section 3, the generation interval of a detection pulse signal is shorter than a time when an integration value reaches a prescribed value in an integration circuit 6 and no reset signal is outputted from the integration circuit. Since a counter 8 is not reset, a detection pulse signal is counted continuously and when the count reaches a set value or above and a write command signal is outputted from a write control section 10 and a central processing unit 12 applies signal processing so as to store tentatively the read data from a light receiving section 4b into a memory 14. Thus, the storage of the read data into the memory 14 is blocked if the moving state and angle are not stable from the start of movement of the image sensor to the arrival of a prescribed distance.
