Title: Method for protecting contents of data of data storing ram
Inventor: TAKAHASHI MINORU
IPC: G06F12/16
Filed: 1982-06-22
Abstract: PURPOSE:To prevent the content of data at the time of restarting from being sharply lagged by preparing a checking RAM in addition to a data storing RAM, and after completing data write in the data storing RAM, writing the upper order byte of the writing data in the checking RAM. CONSTITUTION:In addition to 8-bit areas 2A, 2B an 8-bit area 2C for checking is independently set up in a data storing RAM2. The figure (a) shows the case that the contents Yen03FF of the RAM2 are updated to Yen0400 by writing without any trouble. Namely, the contents of the areas 2A, 2B and 2C are rewritten from 03 to 04, FF to 00 and 03 to 04 respectively. When the succeeding program is to be started by using the contents of the RAM2, a CPU compares the sizes of areas 2A and 2B, and when 2A=2B, uses the contents of the RAM2 as it is. When 2A>2C as shown in the figure (b), the area 2A is kept as it is and the lower order byte of the area 2B is corrected to ''00''. Said procedure is performed on the basis of a property that the data are only slightly changed even if the contents of the RAM2 are reset during the updating.

CONSTITUTION:A silicon nitride film 4 used for a gate insulating film, a first amorphous silicon film 3-a, a second amorphous silicon film 3-b and an n-type amorphous silicon film 7 are formed continuously in a vacuum. Then, the first and second amorphous silicon films 3-a, 3-b and the n-type amorphous silicon film 7 are worked to be a prescribed pattern on a gate electrode and other required parts, and an island layer 3 is formed. Then, in order to form a channel, the n-type amorphous silicon film 7 and the second amorphous silicon film 3-b are removed together. The digging depth of an etching operation has a distribution of about + or -50nm. A layer to be used as a digging margin is formed at high speed and the time for a film formation is shortened. Thereby, it is possible to form a thin-film transistor whose throughput is not spoiled and whose characteristic is good.

Title: Device for reproducing information and method therefor
Inventor: YAMAGUCHI SHIGEO
IPC: G11B11/10
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To optimally set memory lengths in two signal recording areas for different regenerative signals in quality respectively. SOLUTION: A header area formed with an address, etc., by embossing work and a data area where a data is magneto-optically recorded and reproduced exist on a magneto-optical disk 6. The regenerative signals form these two areas are changed by a changeover signal S. The changeover signal S is received, by an SMU 134 of a viterbi decoder 130 to change the memory length of a status memory to be different between the header area and the data area. Since the quality of the regenerative signal is better in the header area, the memory length for processing the regenerative signal from the header area is set shorter than the memory length for processing the regenerative signal from the data area. Thus, the optimum memory lengths are set for the header area and the data area respectively.

IPC: G01C19/72
Filed: 1986-05-12
Abstract: PURPOSE:To make feedback systems unnecessary, and achieve a simple constitution, by applying a broad-band spectrum laser to a laser light source. CONSTITUTION:By applying a broad-band spectrum laser BSL(which contains a super luminescence diode) to a light source, a laser beam having a half value width whose 2DELTAlambda is 10-100nm with a peak wavelength lambdaP as the center is obtained. When an input angular velocity OMEGA=0, the closed optical path lengths in the clockwise direction CW and in the sounterclockwise direction CCW of a passive-type ring optical resonator PRR are equal to each other, and a laser beam having a wavelength lambdaP is in resonance in the respective optical paths. When OMEGA=OMEGA, the optical path lengths in the directions of CW and CCW of the passive-type ring optical resonator PRR apparently expand and contract due to Sagnac effect, and a difference between the resonant frequencies in the directions of CW and CCW generates. Rotation quantity can be obtained thereby.
