Title: Flash memory writing method
Inventor: YAMAGISHI TORU
IPC: G06F12/00
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the waste time and to shorten the write time of a flash memory by adding a delay processing step between a program command sequence write processing step and a data polling processing step to delay the delay time dependent on the frequency distribution characteristic of write time of the flash memory and also the data polling processing. SOLUTION: In regard to a flash memory writing method, a program command sequence write processing step is prepared to write the specific data into a specific address of a flash memory. Then a delay processing step is added between the said write processing step and a data polling processing step which reads the data out of the flash memory and decides them to confirm whether the data are actually written into the flash memory. The delay processing step delays the delay time dependent on the frequency distribution characteristic of write time of the flash memory and also the data polling processing. Then the frequency distribution characteristic is previously decided and a time t3 when most of all write operations are over is defined as a delay time.

Title: Control system of sign polarity
Inventor: ONO TATSUHIRO
IPC: H03M5/04
Filed: 1983-02-17
Abstract: PURPOSE:To perform signal transmission even when a transmission line and a terminal are erroneously connected in polarity by detecting the polarities of frame synchronizing signals on a down and an up lines at each terminal, and performing signal reception and transmission in response to the detected polarities. CONSTITUTION:A frame synchronizing signal sent from a center device 1 to the down line R is sent back to the up line T by a bus terminator 2. The frame synchronizing signal of the down line R is expressed as a predetermined bit pattern and respective terminal devices 3-5 detect the polarity of the frame synchronizing signal of the down line R to receive a signal sent through the down line R in response to the polarity. Further, the polarity of the frame synchronizing signal sent back to the up line T is detected and the signal is sent out to the up line T in response to the polarity. Therefore, even when the chip and ring polarity of the transmission line is incorrect, the polarity of the signal of each device is decided and controlled at its input/output point, so connections are made without paying attention to the polarity of the line.

Title: Sample hold circuit
Inventor: ISHIBE MANABU
IPC: G11C27/02
Filed: 1984-02-15
Abstract: PURPOSE:To reduce noise generated in a sampling period by limiting the frequency band of a sample holding means to the prescribed range of frequency, and providing a filter for compensating a frequency characteristic to the prestage. CONSTITUTION:The output of an amplifier 1 for voltage gain is supplied to a hold capacitor 3 through a sampling switch 2 and a resistance 6, and a frequency response characteristic in correspondence to the output of an amplifier 4 for voltage gain is decided from an input of the amplifier 1 in accordance with a time constant of the resistance 6 and the capacitor 3. On the other hand, the frequency response characteristic is compensated by an prestage filter 5, becomes flat and an analog signal supplied to the capacitor 3 goes to an original frequency characteristic. As a result, when the band of a sample holding means is set below a half of the sampling frequency, the characteristic is compensated. Assuming that the band is a half of said frequency or below, the noise of the amplifier 1 and the switch 2 are reduced, and S/N of the sample hold circuit is improved.

Abstract: PURPOSE:To obtain the optical semiconductor with which an insertion loss and propagation loss are negligible, low-voltage driving is possible and a wide wavelength variable range is obtainable by forming the semiconductor into a p-i-n-i-p or n-i-p-i-n structure provided with the waveguides as i layers in such a manner that electric fields are applied independently to two layers of the laminated waveguides. CONSTITUTION:A directional coupler constituted of two layers of the laminated semiconductor waveguides 1, 2 is constituted. The layer constitution including two layers of these semiconductor waveguides 1, 2 is the p-i-n-i-p or n-i-p-i-n structure. Two layers of the semiconductor waveguides 1, 2 are both constituted of the i layer and the voltage impression is independently controlled through the p-i-n structure.

The change in the refractive index arising from the refractive index control of the 1st waveguide 1 is, therefore, compensated by using the optical amplification in the 2nd waveguide 2 and always a stable transmission gain is obtd. regardless of wavelengths.
