Title: Preparation of semiconductor device same
Inventor: YAMAMORI NOBUAKI
IPC: H01L21/76
Filed: 1983-11-28
Abstract: PURPOSE:To obtain a semiconductor device of high reliability with a high yield, by providing a process wherein, after an element separation region is formed by using a selective oxidation method, a nitride film used as a mask for selective oxidation and an oxide film located thereunder are moved, and thereafter a thermally-oxidized film is formed on an active region. CONSTITUTION:After an unnecessary part of a nitride film 3 is removed, selective oxidation is conducted with the remaining part of the nitride film 3 used as a mask to form an oxide film 4 for separation of an element. Next, the nitride film 3 used for the selective oxidation is removed, and further an oxide film 2 located under the nitride film is removed, whereby a stress 5 is eliminated. Thereafter, an oxide film 11 is formed on an active region by thermal oxidation, and then the oxide films 11 and 4 formed theretofore are removed slectively so as to form an active region. Concretely, a nitride film 7 and an oxide film 7 are formed by a CVD method and then removed selectively, and next, with the nitride film 6 used as a mask, the oxide film 11 on the active region and the oxide film 4 formed by the selective oxidation are partically removed. On the occasion, no abnormal etching occurs since the stress in the oxide films is eliminated beforehand.

Title: Semiconductor device and manufacture thereof
Inventor: EMA YASUSHI
IPC: H01L21/8247
Filed: 1988-09-07
Abstract: PURPOSE:To perform writing and erasing readily even at a low voltage by relatively increasing the voltage between a floating gate and a semiconductor substrate. CONSTITUTION:Since a recess shaped groove is formed in the side surface of a floating gate 12, the surface area is largely increased. The capacitance between the floating gate 12 and a control gate 16 is largely increased. Therefore, the capacitance ratio between the capacitance between the control gate 16 and the floating gate 12 and the capacitance between the floating gate 12 and a semiconductor substrate 2 at a channel region becomes large. Even if the voltage of the control gate is constant or a low voltage, the voltage between the floating gate 12 and the semiconductor substrate 2 at the channel region becomes relatively high. Thus writing or erasing can be performed readily by using the low voltage.

Title: Measuring apparatus of distance of movement of workpiece
Inventor: KUBOTA YUJI
IPC: G01B7/00
Filed: 1989-08-30
Abstract: PURPOSE:To enable execution of measurement by one detector even when a stroke larger than the range of measurement of the detector is measured, by forming a touch lever out of a first contact element coming into contact with a workpiece when the workpiece is located at the rise end, and a second contact element coming into contact with the workpiece when it is located at the lower end, and by detecting the position of the touch lever by the detector. CONSTITUTION:When a workpiece 8 is located at the position of a workpiece rise end 8A, a contactor 1 is brought into contact with the workpiece 8 by the force of a spring 5, and the position of the contactor 1 is detected and stored in such a manner that an arm 4 comes into contact with a contact part 12 and the position of the contact is read by a detector 17 and stored in an electronic micrometer 7. Next, when the workpiece 8 is moved and brought to the position of a workpiece fall end 8B, the contactor 1 comes into contact with the workpiece 8 under its own weight and by the force of a spring 5 and the arm 4 comes into contact. The position of the arm 4 at this time is read by the detector 17 and stored in the meter 7. Then, the values of the rise end 8A and the fall end 8B are compared with master values and a distance 8C of movement of the workpiece 8 is computed by the meter 7.

Title: Train approach alarm receiver
Inventor: ARIMORI YUKIO
IPC: B61L23/00
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To enable a train approach alarm receiver carried by a guard of a work area of a train track to detect the failure of transmitter sending out train approach alarms by transmit waves of constant intervals, by alarm sound. SOLUTION: A receiver is provided with a carrier SQ circuit 11, a switch 12, a rectifier 14, cycle judging circuits 13, 15, an alarm sound oscillator 16 and an alarm control part 17. Since modulated radio waves are sent as tone signals at the time of no train and as message signals at the time of the presence of a train at constant intervals from a transmitter, output of the SQ circuit 11 is inputted to the timer 13 to check the interval of intermittent transmission, and when the switch 12 is on, wave detection output is rectified by the rectifier 14, and whether the tone signals or message signals are at constant intervals is checked by the cycle judging circuit 15. The alarm control part 17 judges the failure of the transmitter if a receive level is low or the interval changes from the checked result, and outputs failure alarm sound from a speaker 84.

Title: Voice packet transmission device and reception device
Inventor: SHIMOKOSHI KIYOSHI
IPC: H04L12/00
Filed: 1989-09-01
Abstract: PURPOSE:To reproduce a superior voice waveform by identifying voice information and end information from packet information which are added for respective packets. CONSTITUTION:When an output from a hangover addition means 102 is inputted to a packet information addition means 103, end information showing the end of a sound section is added to respective packets considered to be the sound section in sound/silence section detection means 101 and voice information showing that it is the packet in the normal sound section to the packet of the normal sound section except for the section with a series of sequence number. When a reception packet is not arrived in a reception-side, it can be judged whether the cause is the abolishment of the packet or a silence by identifying packet information added to the packet. Thus, the deterioration of the voice reproduction waveform on the reception-side is reduced.

Title: Magnetic storage element and its manufacture
Inventor: MATSUDERA HISAO
IPC: G11C11/14
Filed: 1990-08-27
Abstract: PURPOSE:To improve the storage density by sectioning a ferromagnetic material film in stripes whose width is much less than the film thickness of the ferroelectric material film. CONSTITUTION:Striped grooves which are as deep as a magnetic garnet film is thick and have a constant period are formed at right angles to the in-surface easy-axis direction of the film. Namely, the grooves are formed and the striped areas 1 which are sectioned with the grooves are regarded as rectangular thin layers which have long sides in the length direction of striped film sectioning and short sides in the film thickness direction. The rectangular thin layers have uniaxial magnetic anisotropy at right angles to the layer, so magnetic domains 3 are formed and storage areas including their magnetic walls as transfer paths are formed. The length direction of the transfer paths of the magnetic domains 3 is perpendicular to the film surface. Consequently, data which is stored as a Bloch pair can be transferred from the film surface to the substrate side 4 and returned from the substrate side to the film surface reversely, thereby improving the recording medium.

Title: Manufacture of semiconductor device
Inventor: SHIRAISHI HITOSHI
IPC: H01L21/3065
Filed: 1987-09-08
Abstract: PURPOSE:To prevent exposure at protruding parts of lower layers and obtain a flat interlayer film, by forming a resist selectively at recessed parts of the surface of an interlayer film and etching only a part where the surface of the interlayer film is not coated by the resist. CONSTITUTION:A gate oxide film 21, a polysilicon pattern 22, and an interlayer oxide film 23 are formed on a semiconductor substrate 20 and a resist 24 is coated. The resist 24 is patterned on a reversed one of the polysilicon pattern 22 of a base to form a resist pattern 25 and then, the interlayer oxide film 23 is wet-etched by using the resist pattern 25 as a mask. After that, a flat and smooth interlayer oxide film is obtained by stripping and heat-treating the resist pattern 25. As a result, the scattering in the amount of etching is so small that exposure at the polysilicon pattern 22 of the base is limited even at a place where etching is carried out at a maximum speed.

Title: Self termination type electricity connector
Inventor: WEINSTEIN DAVID
IPC: H01R13/66
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To provide an electric connector which can self-terminate electric signals by transmitting electric signals when connected with a connection connector and producing impedance between a connector main body and a center conductor when disconnected form the connection connector. SOLUTION: When a connection connector is inserted into a connector main body 1 form the front face 2 of the main body, a plunger 15 is moved backward due to the function of a conductive spring and the contact between a first spring end part 12 and a center conductor 4. When the connection connector is disconnected from the main body front face 2 of the connector main body 1, the plunger 15 is moved forward due to the function of the conductive spring 11 and reaches a front position. As a result, an inclining face 16 for connection moves backward and the contact of the first spring end part 12 and the center conductor 4 is recovered.  In this situation, when a conductor rear face 3 is connected with a coaxial electric power source, an impedance signal is transmitted between the connector main body 1 and the center conductor 4 and all of the signals produced from a receptacle connector are removed.

Title: Electrochemical machining device
Inventor: NORIMATSU SHIZUO
IPC: B23H3/00
Filed: 1994-09-20
Abstract: PURPOSE: To make yet more precision electrolysis achievable by installing an electrolyte dispersing means, dispersing and rarefying an electrolyte flowing into a minute dent generating regional part of a machining object, in the outer boundary of an electrode to be opposed to this machining object. CONSTITUTION: A cylindrical dent (b) is installed in the central underside of a prismatic electrode 2. An electrolyte supply hole (a) leading to this dent (a) is made in a central part of this electrode 2. In contact with each side face of the electrode 2, each of rectangular sectional electrolyte dispersing ducts 5 is installed there. During electrochemical machining, high-pressure air is sprayed toward a minute dent generating region 6 from a lower end of this duct 5. Then an electrolyte flowing out from the central part of the electrode 2 is dispersed and rarefied. Therefore, since the electrolyte is not almost flowing on top of a work material 3 of the minute dent generating regional part, it is not electrolyzed at all, whereby any minute dent becomes unproduced.

Title: Neural network for generating membership function
Inventor: MURAJI TETSURO
IPC: G06G7/60
Filed: 1992-07-31
Abstract: PURPOSE:To prevent any abnormal change caused by the learning of membership function characteristics by preventing the coefficient of coupling between an intermediate cell and an output cell from being learnt. CONSTITUTION:Among cells 1-5, the cell 1 is a special cell, is called as a bias cell and always outputs '1'. In this case, although coupling coefficients W1, W2, WB1 and WB2 are set, the coupling coefficient of the cells 3 and 5 and that of the cells 4 and 5 are respectively set to '1' and '-1' and no learning is performed. Further, the input function of the cell 5 is defined as an identity function shown by y=x, and the input/output function of the cells 3 and 4 is defined as a sigmoid function shown by y=1exp(-x)/1+exp(-x). However, the (x) is the total sum of inputs to the cells, and the (y) is the outputs of the cells. Therefore, the abnormal change caused by the learning of membership function characteristics is prevented, and membership functions to be outputted cross at the midpoint of grade. As a result, the membership functions are prepared by unbiased position functions.

Abstract: PURPOSE:To suppress vibration and to make it possible to transfer a minute pattern to a substrate without adverse effects on the resolution of a semiconductor exposure apparatus using this substrate holding apparatus by making the introducing direction and the guiding-out direction of liquid medium with respect to the flow path of the liquid medium agree with the direction of the highest rigidity approximately. CONSTITUTION:The introducing direction of liquid medium into a flow path and the guiding-out direction of the liquid medium from the flow path are made to agree with the direction of the highest rigidly approximately in supporting of a substrate holding apparatus 1 with stage means 4a, 4b and 4c. At the time of the inflow and the outflow of the liquid medium, the force of the motion of the liquid medium strongly acts especially in the inflow direction and the outflow direction with respect to an inlet port 1a and an outlet port 1b for the liquid medium, and vibration is generated. The inflow direction and the outflow direction of the liquid medium are made to agree approximately with the direction of the highest rigidity in supporting of the substrate holding apparatus 1. Then, the vibration caused by the flow of the liquid medium is minimized. Thus, the vibration affecting resolution can be decreased.
