IPC: G11C16/08
Filed: 1993-05-28
Abstract: PURPOSE:To drive word lines at a high speed with a less number of transistors under the voltage required not only for writing and reading out operations, but also for erasing operations in the unit of word lines. CONSTITUTION:Output MOSFETs Q52 and Q53, feedback MOSFETs Q54 and Q55, and separation MOSFETs Q56 and Q57 having different conductivities are symmetrically provided against two routes for receiving the output of a logic selection circuit LOGS. The transmission of a negative erasing voltage Vee and writing voltage Vpp supplied to the above-mentioned routes through the feedback MOSFETs Q54 and Q55 to the circuit LOGS is surely inhibited by using the pair of separation MOSFETs Q56 and Q57 having different conductivities. CMOS transfer gates TG1 and TG2 can be adopted as the elements which select the positive or negative logic output of the circuit LOGS and the amplitude of the logic signal of the circuit LOGS can be maximized against the operating power source.

Title: Method for measuring depth of concave face of soft contact lens
Inventor: OOSUMI SHINZOU
IPC: G01B5/02
Filed: 1978-12-07
Abstract: PURPOSE: To accurately and easily measure the depth of the concave face of a soft contact lens by a contact stylus while placing the concave face on the lower side of the lens under water, by keeping the top of the convex face of the lens out of the water.  
     CONSTITUTION: A container 1 is filled with water 2. A soft contact lens 3 is set in the center of the water 2 so that the concave face of the lens is located on its lower side and the top of the convex face of the lens remains over the water. A contact stylus 6 has a threaded part 7 and is moved up by rotating a knob 9. The moment the tip 5 of the contact stylus 6 comes into touch with the bottom 4 of the concave face the indicated value of graduations 8 is read to determine the depth d of the concave face. When the top of the convex face of the lens is in contact with the surface of the water, the lens is prevented from horizontally rocking. This results in accurately and easily measuring the depth of the concave face of the lens.

Title: Image communication device
Inventor: YAGI NOBUO
IPC: H04N1/32
Filed: 1992-06-11
Abstract: PURPOSE:To shorten the restricting time of an operator when he is made to perform an original reading transmission by providing an input mode setting means operating the designation of a transmission destination while the reading operation of a set original is performed. CONSTITUTION:When a power source is turned ON and an initializing operation is terminated, a main control part 1 checks whether a key input is performed for an operation panel 4 or not. When the key input exists, whether an original is set or not is checked. When the original is set and the reading/storage of the image information of the original from the operation panel 4 is instructed, the image information read by a reading part 82 is inputted in a RAM for image 11 and is stored/accumulated after a compression processing is performed for the image information in an encoding/decoding control part 10. The control information on address information, etc., is written in a RAM for control 3 and the registration of a communication job is completed. Thus, as the reading of a set original can be started earlier and a transmission destination can be designated by utilizing the time when the original is read, the restricting time of an operator can be shortened.
