Title: Data erasing method for nonvolatile semiconductor memory element
Inventor: HAMADA MINORU
IPC: H01L29/788
Filed: 1977-11-11
Abstract: PURPOSE:To secure an easy and economical IC formation for the memory array with no conversion of the memory element to the depletion mode by applying the erasion voltage to the drain via the high output impedance circuit. CONSTITUTION:The variation of threshold level Vth of the memory element is shown by the soild line at the erasion time (erasion voltage VE) and by the broken line at the writing time (writing voltage VW) respectively. With application of VE to terminal 16, the potential of drain 13 becomes nearly identical to that of terminal 16, and Vth changes to the positive direction as shown by the arrow with the electron injection to floating gate 14 to carry out the erasing action. And when Vth approximates OV, resistance RSD between source 12 and drain 13 decreases suddenly. In this case, if the resistance value of resistance 15 is selected large enough in comparison with RSD, the potential of drain 13 lowers sufficiently compared with the potential of terminal 16. Thus, the erasing action is self-controlled, and such memory element never be changed to the depletion mode.

Filed: 1994-06-17
Abstract: PURPOSE: To achieve the operation of a blower in high efficiency and low noise by positioning the input tip of a propeller fan and the opening point of a bell mouth on the same line. CONSTITUTION: A blower comprises a propeller fan(PF) which is rotated by a motor 30, a bell mouth 20 surrounding the PF 10 and a bracket 40 supporting the motor 30 fixed to the bell mouth 20. At this point, the fan rotation and the air-streaming operation noises of the PF 10 are generated in the blower. Therefore, the design factor of the bell mouth 20, together with the design factor of the PF 10 becomes important for determining the performance and the noise in the blower. The noise level and the performance of the blower caused by these changes are measured, and the blower is formed as follows. The inner diameter of the bell mouth is formed at 1.5±0.02 times the outer diameter of the PF 10. Furthermore, the width of the bell mouth 20 is formed at 0.468±0.068 times the width of the PF 10.  Then, the curvature of the bell mouth 20 is formed at 0.032±0.014 times the outer diameter of the PF 10.

After wheels have passed the rail, the piston 3 is tried to return by a spring 4, however, the valve disk 7 is seated on a valve seat 3A and rapid rising of the piston 3 is prevented. In this case, both of the rooms 2A, 2B are communicated through a passage 8, provided with a variable orifice 10 therein, and a pipe 11, thereby, the piston 3 is returned slowly. An opening area of the variable orifice 10 is varied by a valve body portion 12A of an adjusting rod 12 made of materials which are remarkably expandable by heat.
