Title: Slicing method for ingot of semicondutor single crystal
Inventor: NATSUME YOSHINORI
IPC: H01L21/304
Filed: 1981-07-29
Abstract: PURPOSE:To reduce the time lapse variation of an inner edge blade, by previously coating the ingot with a resin when slicing the ingot of a semiconductor single crystal with an inner edge type slicing machine. CONSTITUTION:The outer boundary surface of the ingot 1 of an Si single crystal to be sliced is coated with the epoxy resin layer 11a approx. 5mm. in the film thickness to a resin coated ingot 11. Next, this ingot 11 is fixed on a support base 2 with an adhesive, and the inner edge type blade 3 is pressed against the surface of the ingot 11, thus slicing it. In this manner, the blade 3 slices first the resin layer 11a which is softer and smoother than the Si single crystal body. Therefore, the deformations of the thin blade 3 is prevented, and blurrings are restrained resulting in good dimensional accuracy of a wafer.

Filed: 1990-05-08
Abstract: PURPOSE:To index and display lots of information by circulating display information for each display information group for a prescribed time and repeating a procedure selecting display information being displayed by a setting request from a button so as to obtain desired information. CONSTITUTION:A memory control section 13 writes received information to a display information group area 150 upon the receipt of one display information group including at least one set of display information from an information call control section 12 and drives a display control section 14 when the write of the reception information is finished. Since the memory control section 13 receives a request of display information from the display control section 14, the memory control section 13 extracts the display information of first priority from the display information group area 150 and sends it to the display control section 14. Upon the receipt of a setting request of the display information before a request of succeeding information from the display control section 14, the memory control section 13 retrieves the display information group area 150 from the display information being transferred or the display order to read the call address. When the call address is a final information index, the memory control section 13 is restored while awaiting the reception of an interrupt signal.

Filed: 1988-05-17
Abstract: PURPOSE:To obtain an uniform record density, by judging the tone level of a record signal and accumulating predetermined thermal storage index corresponding to the tone level, thereafter controlling a pulse signal such that the record density for same gradation is made constant based on the record signal and the accumulated thermal storage index. CONSTITUTION:A tone level signal is fed through an input terminal 1 and a judging circuit 2 judges the tone level of the tone level signal and provides a corresponding thermal storage index to a first selector 3. The first selector 3 sequentially selects the tone level signal judging circuit 2 and one counter in a thermal storage index counter circuit 4 and connects them each other. Thermal storage index is stored through each counter for every heating resistor during an interval from start of record to a record line, while a second selector 5 sequentially selects one counter in the counter circuit 4 and a pulse generator 6 and connects them. A pulse signal is generated based on the tone level of the tone level signal and the accumulated thermal storage index then the pulse is applied onto the thermal head 7. Number of pulse in the pulse signal is corrected in the paper feed direction thus optimizing the amount of heat to be produced from each heating resistor.
