Title: Thermal recorder
Inventor: HOBO YOSHIHIRO
IPC: H04N1/405
Filed: 1984-06-19
Abstract: PURPOSE:To compensate the nonlinearity of color development density characteristic to perform multigradation control in a wide temperature range by reading out time information corresponding to a gradation from the second storage part when heating is controlled a number of times corresponding to the gradation and determining the time of each heating driving on a basis of this information. CONSTITUTION:An A/D converting circuit 4 outputs a demodulated picture element signal having 16-stage gradation information, and a selector 6 leads into a storage part 7 or 8 selectively on a basis of a switching signal MSEL. 2048 picture elements corresponding to one scanning line are stored in storage parts 7 and 8. The read address of a read address counter 14 consists of 11 bits of the total of upper and lower outputs, and picture elements are read out from storage parts 7 and 8 16 times in 256-picture element unit. The middle output is inputted as a 4-bit gradation signal to an input B of a comparator 15. This signal is changed at every read time. The comparator 15 compares inputs A and B with each other to picture element signals ''1'' or ''0'' successively. Consequently, picture element signals of storage parts 7 and 8 heat a head 2 a number of times corresponding to the gradation. A processor 16 makes the signal width of an enable signal ENB different each time when 8 signals ENB are given to the head 15 times. Time information indicating the signal width is stored in a ROM17.

IPC: G01D5/249
Filed: 1988-05-25
Abstract: PURPOSE:To detect the disconnection of an absolute encoder at a low cost and safely by comparing the increase/decrease rotating direction of an incremental encoder and the data increase/decrease rotating direction of the absolute encoder. CONSTITUTION:By reading output data D1 of an incremental encoder 6, the increase/decrease rotating direction of the encoder 6 is decided. Subsequently, by reading output data D2 of an absolute encoder 3, the increase/decrease rotating direction of encoder output data is decided. This data D2 and data D3 outputted from the encoder 3 in the next time are compared, and except the case when an absolute value of a difference of the data is <='1', or coincides with the maximum value of an output of the encoder 3, it is decided to be disconnection abnormality of the encoder 3. Also, the increase/decrease rotating direction of the encoder 6 and the data increase/decrease rotating direction of the encoder 3 are compared, and unless they coincide, it is decided to be disconnection abnormality of the encoder 3. In such a way, the disconnection of the absolute encoder can be detected at a low cost and safely.

Filed: 1985-06-14
Abstract: PURPOSE:To reflect a memory access request on a main storage by invalidating a flag for displaying the validity of a main storage physical address to be separated in a conversion table after the end of the execution of cache discharging operation. CONSTITUTION:At the separation of the main memory, V bits are reset by a V-bit reset means 15 after the execution of cache discharging operation. When a memory access request accompanied with a memory address for indexing a conversion table 8 in which a main memory physical address to be separated is registered is generated during a series of operation for cash discharging, the memory request can be reflected on the main memory if a directory memory 9 in which the memory address of the memory access request is registered is not invalidated. The address of a storing request generated after invalidating the memory 9 is stored and the cache discharging operation is continued, so that stored data can be reflected on the main storage.

Abstract: PURPOSE:To improve the reproducibility of characteristics of a semiconductor device and to reduce the rate of defects by forming different impurity densities of semiconductor regions which are contacted with a gate electrode from those of regions which are contacted with source and drain electrodes. CONSTITUTION:A no-addition GaAs buffer layer 12 and an N type layer 13 of 105X 10<17>cm<-3> in density are epitaxially formed on a semi-insulating GaAs substrate 11, and an AlN film 14 is superposed. Three-layer mask of photoresist 16, Ti 17 and Au 18 is formed on a region 15 to be formed with the gate electrode of an enhancement type FET, O ions are implanted by energy in the prescribed density, and the region is annealed at 600 deg.C for 20min. Since the annealing is performed at the temperature lower than the conventional annealing, no thermal deterioration occurs in a substrate. Then O ions are implanted to 1/2 or more of the thickness of the layer 12 in multistage, the mask is removed, and source electrodes 20, 21 of AuGe/Au, drain electrodes 22, 23 and gate electrodes 24, 25 of Ti-Pt-Au are formed as the conventional one. Since ion implantation is limited to the part directly under the gate electrode and low temperature treatment is performed, the source, drain and channel are maintained in preferable state of epitaxial layer, thereby improving the reproducibility of various characteristics and reducing the rate of defect.
