Title: Semiconductor memory
Inventor: KUNO KAZUO
IPC: G11C11/34
Filed: 1985-08-02
Abstract: PURPOSE:To shorten a transition time between a reading and a writing by providing a diode circuit generating the dropping of voltage equal to the dropping of voltage of a load circuit including a diode for clamping a memory cell as a reading and writing control circuit. CONSTITUTION:A voltage level shifted by a diode DR2 connects a load resistance RRE1 to its emitter and supplies a resistance RR to the base of an emitter follower type transistor QR1 connected to its collector. By equally setting the on voltage of the diode DR2 for the level shifting to an on voltage between the base and the emitter of the transistor QR1, the dropping of voltage between both ends of the resistance RR1 becomes equal to the dropping of voltage of a diode circuit DDC consisting of a diode DR1 and a resistance RR1. The dropping of voltage of both ends of a resistance RRE2 becomes equal to the dropping of voltage of the diode circuit DDC. Thereby, the reverse time of a memory cell transistor can be stabilized at high speed.

Title: Sole flooring slippage testing machine
Inventor: NAGATA HISAO
IPC: G01N19/02
Filed: 1988-07-11
Abstract: PURPOSE:To measure a slippage resistance by a dynamic friction by moving a mobile floor horizontally keeping shoes keeping contact with the mobile floor to detect a horizontal load and a vertical load working on the shoes and a floor surface. CONSTITUTION:When a slippage resistance by a dynamic friction is measured, a spring 17 is forced not to function by tying a wire between both ends of the spring 17 or other operations. Then, the shoes are put on a foot model 38 while a loading weight 68 is suspended at the tip of a loading arm 66.

IPC: G03B3/00
Filed: 1987-07-10
Abstract: PURPOSE:To keep a bit rate at a time to A/D convert a focus evaluating value in a necessary minimum by providing a subtracting means to obtain the differential value of a prescribed component per prescribed period and minimumizing the range of an analog signal inputted to an A/D converting means. CONSTITUTION:A sample and hold circuit 34 samples the output of a detector 32 according to the signal of a timing corresponding to the vertical synchronizing signal of a video signal and holds it for an IV period. A substracter 36 substracts the hold value of the sample and hold circuit 34 from the output voltage of a detector 32 and outputs the substracted voltage. An amplifier 38 amplifies the output voltage of the substracter 38 and impresses it to an A/D converter 40. An operation processing circuit 42 adds the output of the A/D converter 40 per IV, calculates the driving direction and the driving speed of a motor 24 and outputs them to a D/A converter 44. Thus, since a little bit number can be efficiently used and a digital value can be accurately reproduced, the accuracy of a down-hill control can be enough secured.

Title: Digital automatic gain control system
Inventor: KAKO TAKASHI
IPC: H04B3/06
Filed: 1983-09-16
Abstract: PURPOSE:To attain stable control from a high input level to a low input level by providing plural integration sections and constituting a gain coefficient multiplication section multiplying a gain coefficiency corresponding to each integration section into plural stages. CONSTITUTION:The switching control changing respectively gain coefficients C1, C2 and C3 is performed by a discrimination section 31. The integration section 4-1-4-3 have values of, e.g., +2, +2, -2 at present, then the gain coefficients C1, C2 and C3 take values of +2, +2 and +1. When an output of an error calculating section 3 has a further positive value in this state, the discrimination section 31 obtains a value of alpha3 by using an output of a slicer 32 and leads error information to the integration section 4-3. On the other hand, when the slicer 32 detects negative error information, the discrimination section 31 leads the error information to the integration section 4-2 by deciding the value of alpha2 so as to control the gain coefficient C2 to be changed. The switching control is performed similarly in other state.
