Abstract: PURPOSE:To prevent cracking and crazing when silica glass is produced by a sol-gel process by hydrolyzing silicon alkoxide in a specified solvent. CONSTITUTION:When silicon alkoxide whose alkyl moiety is preferably 1-4C alkyl or a partial polycondensation product thereof is hydrolyzed in a solvent, 1-methyl-2-pyrrolidone and polyalkylene glycol and/or a deriv. thereof are added to the solvent. Silica sol formed by hydrolysis is poured into a vessel such as a laboratory dish, converted into gel by holding at room temp. to 70 deg.C and dried at room temp. or above for several weeks. The resulting dry gel is sintered by heating to 1,000-1,400 deg.C to obtain silica glass.

Filed: 1984-10-09
Abstract: PURPOSE:To prevent the influence of the ground of an original pressure plate from being exerted on a copy image by switching the color of the original pressure plate to black or a specular surface during original size detection or to white during copying operation. CONSTITUTION:An original exposure lamp 4 is turned on during original size detection to scan original glass 2, and a black sheet 8 is set as the sheet of the original pressure plate 1 facing an original 3.

Title: Over temperature detection circuit
Inventor: ABE TETSUO
IPC: H01L21/822
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of detected temperature by setting a threshold value for deciding an over temperature based on the outputs from an A/D conversion circuit detected, respectively, at a constant normal temperature and under high temperature state at the time of burn-in. SOLUTION: Upon receiving a normal temperature data read command from a communication port 311, a CPU 302 reads in the voltage from a temperature sensor 307 through an A/D conversion circuit 308 and stores the voltage in an EEPROM 304. At the time of burn-in, the CPU 302 receives a burn-in data read command from the communication port 311 and reads in the voltage from the temperature sensor 307 through the A/D conversion circuit 308. A temperature coefficient is then calculated based on the voltages from the temperature sensor 307 at the time of normal temperature and high temperature and a threshold value is generated from the temperature coefficient and stored in then EEPROM 304. The threshold value is read out except the burn-in time and set in a threshold value register within the CPU 302 and compared with the voltage from the temperature sensor 307.  If the threshold value is exceeded, a relay is turned off and a countermeasure against abnormality, e.g. interruption of load current, is taken.

Abstract: PURPOSE:To separate a character and a photograph by detecting a picture density and distinguishing the character and photograph of an object picture from a histogram of a detected density. CONSTITUTION:Slice levels 11a, 11b,..., 11n are generated by a slice level generator 10 outputting low to high levels in a prescribed 8-bit digital level different from each other and they are compared with 8-bit information 9-2 at each picture element by a main scanning from a line sensor at comparators 12a, 12b,..., 12n. The obtained frequencies 15a, 15b,..., 15n are integration values in the density ascending order. This has histogram information of a picture, then the density distribution is analyzed through a character photograph discrimination circuit 16 and a data whose specific level frequency is high is discriminated as a character and a data whose intermediate level is equal or has peaks is discriminated as a photograph. Then a frequency counter 14 is cleared and the processing is proceeded to the next line. Thus, the character photograph discrimination at each line of the original is applied automatically.
