Title: Method for creating extremely shallow source/drain expansion part by doping gate and semiconductor resulting therefrom
Inventor: FURUKAWA TOSHIHARU
IPC: H01L21/28
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To form a narrow gate and a shallow expansion part by providing a layer (substrate) including one polysilicon gate and one source/drain region, and by simultaneously doping one gate stack and the source/drain region. SOLUTION: Vapor-phase doping is selectively used, and a polysilicon gate and an S/D region are simultaneously doped. Especially, a gate stack 20 and a well 18 that are not doped are covered with an appropriate diffusion prevention material 40. An S/D region 19 and a polysilicon gate 24 are exposed to n- and p-type gases or a doping source 30 of plasma. The gases can be variously changed corresponding to p and n types. For example, arsine AsH3 is used as arsenic trichloride AsCl3, phosphine PH3, and n-type gas dopant. When a masked laser beam is used, a diffusion prevention material 40 is eliminated, and reaction is repeated for the remaining stack 20 and the S/D region 19 by a type opposite to the doping source being used firstly.

Title: Phase detection circuit
Inventor: OKANO YOSHIMITSU
IPC: H04L27/227
Filed: 1978-09-27
Abstract: PURPOSE:To obtain a detection circut where a low-pass filter, etc., are needless and receiving signals can be detected, by sampling receiving signals by timing pulses and sampling pulses which are generated by using a reference carrier and are controlled on the time base. CONSTITUTION:A phase modulation wave is not only given to sampling circuit 14 as a receiving signal but also supplied to timing generation circuit 15 and reference carrier circuit 16. Timing generation circuit 15 generates a timing pulse synchronized with the receiving signal at every one time slot and sends it to sampling pulse generation circuit 17. Meanwhile, reference wave generation circuit 16 supplies the reference carrier to sampling position control circuit 18 correspondingly to the phase modulation wave. Here, timing pulses and reference sampling pulses are used to sample pulses 20 which have the position controlled on the time base. Receiving pulses 20, sampling circuit 14 samples receiving signals and reads the sample result as it is. As a result, the precision of the sample result is improved, and a low-pass filter, etc., can be made needless.

Title: Method for detecting program cell death or induced cell deth of eucaryotic cell
Inventor: BAANHARUTO TORAOSU
IPC: G01N33/58
Filed: 1994-05-31
Abstract: PURPOSE: To quickly detect apoptosis by coupling one of the respective antibodies of antihistone and anti-DNA to a solid phase, taking the other as a label antibody, incubating a solution of a test cell with the antibodies, and taking a label as a character of a program cell death. CONSTITUTION: In order to emit cytoplasmic DNA fragment from an apoptosis cell, a test cell group is treated with a nonionic surface active agent. After an insoluble component is separated from the obtained dissolved solution, the solution is incubated with an anti-histone antibody and anti-DNA antibody. In this case, before or after incubation, one of the antibodies is coupled to an immobilized antibody by a suitable method such as direct adsorption coupling to a solid phase or the liek. The antibody which is not used for immobilization itself is labelled or another label antibody is added to the antibody to be labelled. After a solid phase is separated from a solid phase, the label coupled to the solid phase becomes a direct character showing the apoptosis in the test cell group. Thus, the degree of apoptosis in the test cell group can be measured quickly and simply.

Abstract: PURPOSE:To obtain a motor core having no dimensional limitation or fluctuation, no sharp edge and requiring no special die in which content of silicon can be controlled freely by adding plastic binder to magnetic fine powder material and kneading, and then injection molding the mixture and baking. CONSTITUTION:Plastic binder is added to magnetic fine power and kneaded and then the mixture is injection molded and baked to produce a core 10A. At that time, the die is rounded so that the coil winding part 12 of the core 10A is not sharpened but rounded. The core 10A is coated with an insulating material 15 prior to winding the coil. Consequently, the film of the insulating material 15 can be made thin. Since the core 10A is made thick or the volume of the winding part 12 is increased within limited overall dimensions, efficiency of motor can be enhanced.

Title: Semiconductor device
Inventor: SHIMIZU AKINORI
IPC: H01L21/31
Filed: 1986-05-22
Abstract: PURPOSE:To prevent wire breakdown in interconnections, by providing the concentration distribution of an added composition, which is increased from a lower layer toward an upper layer on an interlayer insulating film, thereby sufficiently depositing the material of an upper interconnection layer even in a contact hole. CONSTITUTION:An Al-Si interconnection 3 is formed on a field oxide film 2 as the first interconnection on a silicon substrate 1. A phosphorus glass film 4, in which phosphorus concentration is continuously changed, is deposited. As a result, the phosphorus concentration is continuously changed from 0 to 3.5 mol % from the lower layer toward the upper layer in the glass film 4, and the glass film 4 is grown to a constant thickness. Thereafter, a contact hole part 5 in the glass film is etched by using a dry etching method. Since the phosphorus concentration of the phosphorus glass film 4 is continuously changed from the lower layer to the upper layer in the range of 0-3.5 mol %, the side etching amount becomes larger toward the upper layer. The side wall of the contact hole is formed so that it has the slant surface with respect to the surface of the substrate 1. Therefore, when an Al interconnection 6 is deposited as the second interconnection, it is sufficiently deposited in the hole since the side wall of the contact hole is the slant surface.

Title: Band managing method, subscriber exchange and relay exchange for atm network
Inventor: KODAMA TOMOAKI
IPC: H04L47/762
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To shorten call processing time by performing band processing only in the case of requiring a band higher than a set band by operating a subscriber exchange and a relay exchange according to a program for stepwisely changing the band for the virtual path of relay exchange corresponding to a change in the number of originated calls sent out of a terminal. SOLUTION: When the band change step width of virtual path (VP) is defined as S and the respective request bands of originated calls 1 to 3 are defined as (a) to (c), the relay exchange performs following stetting. Namely, when the VP receives the originated call 1 in the state of housing no virtual line at all, because of S>a, the band S is set, and next, when there is the originated call 2 on the VP, because of S>a+b, the band S is not changed. Next, when there is the originated call 3, because of S<a+b+c and 2S>a+b+c, the band of VP is changed into 2S and not at every call end time but at the time point when a certain level is exceeded even in the case of call end, the band is lowered for S. Thus, the band capture processing and call connecting time of relay exchange can be decreased and efficiency in the utilization of band can be improved.
