Title: Double end surface grinding diamond grindstone
Inventor: HAMADA YOSHIMITSU
IPC: B24D7/06
Filed: 1981-08-17
Abstract: PURPOSE: To simplify repair work for a diamond layer, by separately forming a diamond sintered block, in the less worn inside of a diamond layer grinding surface, and fixedly tightening the separated blocks to a grindstone base with bolts.  
     CONSTITUTION: When a diamond layer grinding surface is worn away and required its repair work, upper surfaces of the diamond layer of a block 8', consisting of diamond sintered chips 1', 1", securely fitted to the groove 4' of a  grindstone base in the periphery of a grindstone surface, are repaired by using  a G.C grindstone or the like. On the other hand, blocks 8" of diamond sintered  chips 2', fixedly tightened by bolts 11' from the rear side of the grindstone base  in the inside of the grinding surface, are removed from the grindstone base by  loosening the bolts 11' to process the bottom side of a metal mount of the  block 8" or spacers 10', and then the blocks 8" are reassembled by the bolts 11'  to form the diamond layer of inner and outer blocks in an equal level, thus  repair work of said block 8" is completed.

Title: Manufacture of semiconductor device
Inventor: HAYAFUJI TAKANORI
IPC: H01L21/268
Filed: 1981-08-17
Abstract: PURPOSE:To obtain a semiconductor device with excellent characteristics by a method wherein a supporting body made of an insulator is bonded by welding to a primary surface of a semiconductor substrate and the semiconductor substrate is removed with the exception of a prescribed thickness remaining on the supporting body. CONSTITUTION:A 1-10mum thick N epitaxial layer 2 is laid down on an N<+> type Si substrate 1. A quartz glass pane 3 is positioned in close contact with the layer 2, a 1.06mum long Nd-YAG laser beam is thrown at the glass pane 3, whereby the surface of the N layer 2 is locally fused and welded to the glass pane 3 as it cools off. A water solution of a mixture of fluoric acid:nitric acid:acetic acid=1:3:8 is applied that selectively etches the N<+> layer 1 at a speed 10<3> times greater than it does the N layer 2. The N layer 2 surviving the etching is built into prescribed elements 5. The device thus constructed retains the structural merits of an SOS and the N layer 2, thanks to the homoepitaxial layer grown on the N<+> layer 1, has few lattic defects. A device is obtained that is superior to a conventional SOS type device in terms of characteristics.

Title: Distance calculating system
Inventor: KAMATA SEIICHIRO
IPC: G06K9/62
Filed: 1988-05-26
Abstract: PURPOSE:To perform recognition even when a large number of character categories exist by limiting the character category (n) to calculate a new optimum accumulation value g<n>i with a value decided by the optimum accumulation value less than (i-1) at a request number (i) (i>=2). CONSTITUTION:In a character recognition device provided with a means to calculate the optimum accumulation value g<n>i of distance d<n>i between a feature element ai and the feature element b<n>i of a reference pattern pattern corresponding to the character category (n), the total sum of the distance d<n>i at a path from a point (n, 1) to a point (n, N), that is, the value to minimize the accumulation value is searched in a space stretched by (n) and (i). The optimum accumulation value g<n>i calculated in the process supplies the accumulation value of the distance d<n>i from the point (n, 1) to the point (n, i) of the (n). Concretely, the optimum accumulation value calculated with (i-1) is qualified with prescribed reference, and a set is defined at the point of (n) whose value is small, and calculation to calculate the new accumulation value g<n>i is performed only at the point next to those points. However, a problem that the storage area of the accumulation value g<n>i is large still remains, but, by generating and using a work area calculated newly, the storage for the accumulation value g<n>i not being calculated is not required.

Abstract: PURPOSE:To hold a multidimentional electronic conference and to store and retrieve the conference data and characters and/or graphics drawn on an electronic blackboard by digitally compressing information on the characters and graphics drawn on the blackboard, and storing them. CONSTITUTION:The characters and graphics, etc. drawn on the electronic blackboard 2 are scanned and inputted to a sampling part 22 in form of information signals. The sampling part 22 digitizes the information signals based on sampling signals from a sampling signal generating part 21. That means that, said information of characters and graphics on the board 2 are periodically read in accordance with the inverval set by the sampling signal generating part 21. These digital information signals are converted to a vector in a vector part 23 by taking the variance between the value read immediately before and a currently- read value, i.e. the digital information signals are compressed. This vector information is temporarily stored in a memory part 24, and at the same time is transmitted by a transmission control part 50 to other electronic conference systems through a communication line 6.

Title: Insulated-gate bipolar transistor and its manufacture
Inventor: OKABE NAOTO
IPC: H01L29/10
Filed: 1991-05-31
Abstract: PURPOSE:To prevent a latch-up at a cell adjacent to a pad region for an insulated-gate bipolar transistor and to shorten the turn-off time of the title transistor. CONSTITUTION:A p-type pad well layer 8 is formed on the surface of an n<-> drain layer 2 under a gate bonding pad 15a; the resistance on its surface is made low by a p<++> type pad 9. The p<++> type pad layer 9 is connected to a source electrode via a contact hole 10b. A gate electrode which impresses a gate potential to each cell has a pattern which is extended to be a comb-tooth shape along the boundary between a pad region and a cell region. As a result, the gate electrode does not exist substantially under the pad 15a. The p<++> type pad layer 9 can be formed over the whole surface of the well layer 8 simultaneously with the formation of a p<++> type contact layer 5b after the gate electrode is formed. It is possible to prevent a latch-up caused when minority carriers are concentrated in an edge-end cell 12 thanks to the p<++> type pad layer 9; it is possible to prevent an increase in the turn-off time of the title transistor.
