IPC: F24H1/12
Filed: 1989-05-24
Abstract: PURPOSE: To obtain a central space heating apparatus having long lifetime which can be installed easily while minimizing spatial conditions initial and running costs by filling a chamber and a duct circuit with helium gas under a specified pressure at the working temperature. CONSTITUTION: The chamber 1, ducts 9, 12, 11 and convector 3 of a heating furnace F form a closed circuit.

Abstract: PURPOSE:To construct a memory cell, not accompanying any particular difficulties in manufacturing or in sense, for a 2-bit data memorizing mask ROM by a method wherein low-concentration diffusion is accomplished into a portion of a substrate just under a gate in the vicinity of a source and drain of a cell transistor. CONSTITUTION:In the process of constructing a memory cell of this design, a gate oxide film GI and gate electrode G are attached to a substrate SUB, impurity diffusion is accomplished for the formation by self-alignment of source.drain regions S, D, impurity ions same as the substrate in conductivity type are implanted into the gate-side ends of the source.drain regions, and then a heat treatment is performed for the formation of a p<+>-region provided with an extension as indicated in the figure. Whether the p<+> region is to be formed or not depends upon the data present in storage. Of the source.drain regions, the left-side one will be used as a source in some cases and, in other cases, the right.side one will be used as a source. This means that p<+>-regions must take one of four positions: neither on the left side nor on the right side, on the left side, on the right side, or on both left and right sides. In this way, a memory cell is capable of a 2-bit function, replacing a 4-value level cell.

Title: Defect data fetching circuit
Inventor: OKAFUJI MASAHARU
IPC: G01N21/88
Filed: 1987-05-29
Abstract: PURPOSE:To correct the adjustment deviation of the optical system of a defect detector by providing a shift circuit for a start pulse for resetting a counter to an X-coordinate counter for defect data when ORing defect data of plural scans. CONSTITUTION:The defect detector scans a transparent plate which runs lengthwise with a light spot in the breadthwise direction and detects and outputs the kind, size, position, etc., of a defect to a defect data fetching circuit 40. When the defect data are inputted, an X-axial counter 42 outputs it counted value as X-coordinate position data and a Y-axial counter 14 outputs its counted value as Y-coordinate position data. Further, an X-axial subcounter 41 outputs pulses shifted according to a set offset value to the counter 42 to correct its count start position. An OR unit 12 ORs data of plural scans accumulatively and outputs the result to an FIFO memory 15. Thus, even if the address of a center position shifts, the shift can be corrected by adjusting the optical system of the defect detector.
