IPC: H01L21/76
Filed: 1982-06-22
Abstract: PURPOSE:To prevent the channel width from decreasing, by a method wherein Si substrate is partly etched to produce a base and a groove, the base is masked selectively and the groove is oxidized, and then the mask is removed. CONSTITUTION:SiO2 and Si3N4 are overlaid on Si substrate 117, and positive type resist 111 is applied thereto and plasma etching of C3F8 is performed, thereby a mask 113 without projection is produced. Anisotropy etching is performed using CCl4/C2F6 plasma, thereby a groove 121 of depth about 0.33mu is produced with a side wall 125 in nearly vertical direction. Subsequently B ion may be injected to form a channel stop. SiO2 133 and Si3N4 131 are overlaid, and the mask 131 is removed only at the bottom by anisotropy plasma etching of C3F8. Wet oxidation grows SiO2 145 slightly below the layer 131 and forms SiO2 141 selectively. A gap is produced in SiO2 153 when all of unrequired films  are removed, but deposit of SiO2 by NO2: SiH2Cl2 in volume ratio 2:1 fills the  gap. In this constitution, channel of required effective width is obtained.

Abstract: PURPOSE:To provide a method of manufacturing semiconductor devices including a bipolar transistor realizing reduction of cost and improvement of yield. CONSTITUTION:After forming a buried collector layer 2, an epitaxial layer 3, an element isolating insulation film 4 and a collector wall layer 5 on a semiconductor substrate 1, P-type impurity ions such as boron ions or the like are implanted without using a mask such as a resis formed by the photolithography and this impurity ions are diffused by heat treatment. Boron is introduced on the basis of self-alginment to an epitaxial layer 3 surrounded by the element isolating insulation film 4 to form a P-type intrinsic base layer 7. In this case, boron is also introduced into the collector wall layer 5 within a transistor resion 6 and concentration of phosphorus on the surface region of the collector wall layer 5 is higher than the boron surface concentration after the diffusion by about two digits. Therefore, a carrier concentration on the surface region of the collector wall layer 5 reduced by compensation is very low and increase of collector resistance is negligible.

Title: Preparation of polylactic acid
Inventor: FUKUSHIMA TAKESHI
IPC: C08G63/82
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain a polylactic acid having little color and a high molecular weight even with little or no solvent by carrying out polycondensation using lactic acid as a main source material with addition of a material acting as a ligand of a catalyst and/or a material which can be condensed with the catalyst. SOLUTION: A material acting as a ligand of a catalyst (e.g. a tin catalyst) and/or a material which can be condensed with a catalyst are materials which suppress the formation of coloring material by stabilizing the catalyst as a ligand for the catalyst before the catalyst forms a coloring material from a polymer terminal when a polymer grows to a high molecular weight and unsaturation of the ligands occurs at the catalyst center; which suppress the formation of coloring material by decreasing the catalyst center through condensation with the catalyst; or which have both of these two effects. Preferably these materials are a protonic acid, a polyethylene glycol dialkylether, a metal (compound) selected from Is, Ge, Al and Zn, p-toluenesulfonic acid, or metallic Ge or Si.

Title: Radar tomography
Inventor: KUENTEIN EMU MAAFUI
IPC: A61B10/00
Filed: 1990-04-25
Abstract: PURPOSE: To utilize a radar signal for a medical image processing by using a timer-gate circuit and selecting a reflected radar pulse received and correspond a radiopulse to a specified concerned area in a specified depth within an object. CONSTITUTION: A transmitter 18 and a video processor 26 are synchronized by producing very short continuous pulse rows at equal distances. A synchronizing processor 32 controls a timer-gate 24 to carry out an appropriate scanning control. The timer-gate 24 is a device for selecting a specified pulse from received pulses in order to carry out a spatial control. For example, if a radar pulse is reflected from a lower jaw part of a patient 2, the timer-gate 4 selects only a return pulse having a returning timing from a specified depth. Therefore, only a gate controlled pulse is received for an imaging treatment. A three- dimensional information can be obtained by moving a radar head 6 against the patient 2 and then scanning in a depth direction by a motion of the timer- gate 24.

Filed: 1988-04-30
Abstract: PURPOSE:To inspect the unevenness of all of leads by one time inspection regardless of the number of the leads of an integrated circuit, by confirming the outer shape of each of the leads on the basis of the distance from each of the leads detected by a distance detector and operating the length of the lead from the outer shape of the lead. CONSTITUTION:The distance data from the point of time when an integrated circuit 1 begins to pass a distance detector 11 is successively investigated, and a change point TR from a lead absent state to a lead present state and a change point TF from the lead present state to the lead absent state are calculated to calculate the leading end point C of each pin. This leading end point is calculated as the center point between th3e points TR, TF of each lead or as the average value of the sampling data between the points TR, TF and the outer shape of the lead can be almost confirmed on the basis of the calculated value. The length of each lead to the leading end point C of each lead is set and this data is compared with the standard (upper limit : CP, lower limit : LO) of a preset planned value to make it possible to inspect the unevenness of the leading end parts of the leads.

IPC: G01D1/18
Filed: 1990-04-23
Abstract: PURPOSE:To eliminate the need of an element and a circuit used exclusively for detection and to obtain the device at a low cost by displaying a fact that the input quantity exceeding the initialization is detected, on a display mean. CONSTITUTION:A display LED 11 being a numerical display circuit has a function for displaying an input value, and a microcomputer 3 is a detecting means having a function for detecting the input quantity of initialization. In such a state, when a means for displaying a fact that the input quantity exceeding an initial value is detected, on the LED 11 is provided, various displays can be executed. For instance, when a position of a selecting switch is aligned with a detection display, and a zero-phase current I0 is detected, an LED 40 is turned on, and when a zero-phase voltage is detected, an LED 41 is turned on. In such a way, since an element and a circuit used exclusively for detection becomes unnecessary, the device becomes inexpensive.
