Title: Motor
Inventor: IKUTA HIROSHI
IPC: F16C33/10
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To form an oil film by both a lubricating-oil supply means and lubricating oil with an oil-impregnated bearing, and to lengthen the lifetime of the revolution of a motor and stabilize rotational performance by supplying the oil-impregnated bearing with lubricating oil by the lubricating-oil supply means and holding lubricating oil so as to be leaked by a holding means. SOLUTION: An oil-impregnated slide bearing 8 is composed of a sintered alloy having a large number of pores, the pores are impregnated with lubricating oil, the outer circumferential surface of a shaft 1 is supplied with the lubricating oil from the pores in the lubricating section of a slight clearance between the shaft 1 and the oil-impregnated bearing 8 together with the revolution of the shaft 1, and an oil film is formed and the shaft 1 is rotated smoothly. Since the oil-impregnated bearing 8 can be fed directly with lubricating oil at all times by an oil-impregnated member 11 such as sponge, lubricating oil in the oil-impregnated sliding 8 is not exhausted until supply from the oil-impregnated member 11 is completed. Accordingly, the lifetime of a motor 11 can be lengthened until the supply of lubricating oil in the oil-impregnated member 11 is completed.

Inventor: NAKAMURA YOSHIHIRO
IPC: H01L21/8246
Filed: 1979-03-06
Abstract: PURPOSE:To prevent mixture of phosphorus in an insulating gate when forming the gate in an insulated gate semiconductor non-volatile memory and prevent the memory retaining property from lowering by coating a gate treated with phosphorus and formed in phosphorus glass on the surface and a field oxide film a silicon nitride film. CONSTITUTION:After forming a source, a drain diffused layer 3, a channel stopper 4, and a gate silicon heat oxide film 5 of 1000-15000Angstrom  thick, phosphorus is diffused in a diffused layer 6 at 700-800 deg.C for 3-5min, and then a silicon nitride film 7 is formed with 200-600Angstrom . Then, the portion forming a multilayer insulated gate is dry etched. Then, the film 7, and the films 5, 6 are removed, and a heat oxide film 8 is formed at 900-950 deg.C to form a multilayer insulated gate thereat. Thus, a gate formed with phosphorus in glass and a field oxide film are coated with a nitride film. Accordingly, it can prevent the memory retaining property from lowering by preventing the phosphorus from entering into the multilayer insulated gate oxide film.

IPC: G11C11/14
Filed: 1983-02-18
Abstract: PURPOSE:To prevent the degradation of the bubble operation characteristics due to warp or distortion, by implanting ion in the rear face of a substrate also to eliminate the warp of the crystal substrate which is generated by ion plantation for hard bubble suppression. CONSTITUTION:Neon ion (Ne<+>) for hard bubble suppression is inplanted in the surface of a crystal substrate 10, which is attained by growing epitaxially in liquid phase a magnetic film consisting of, for example, a (YSmLuCa)3(FeGe)5O12 on a polished GGG (gadolinium gallium garnet) substrate consisting of Gd3Ga5 O12, with 50keV acceleration voltage and 10<14>/cm<2> dose. Warp is generated by this ion implantation. Therefore, ion is implanted in the rear face of the substrate also to eliminate warp of the substrate and its distortion. Thus, the degradation of the bubble characteristic is prevented by an easy means to avoid warp of the substrate due to sticking of a protection film and an insulating film.

IPC: C04B35/64
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain a member excellent in gas permeability, having very high mechanical strength and suitable for a filter by compacting and sintering a mass of inorg. particles without using an auxiliary to form an inorg. sintered porous compact having a specified thickness and a specified porosity. SOLUTION: A mass of inorg. particles is compacted and sintered without adding an auxiliary to obtain the objective inorg. sintered porous compact having 0.4-1.5 mm thickness and 10-40% porosity. The inorg. particles are preferably high purity a-alumina having 0.3-0.5 μm average primary particle diameter. The sintering is preferably carried out by a spark plasma sintering method.

Title: Image pickup device
Inventor: TAKENAGA HIROYUKI
IPC: H04N9/07
Filed: 1987-02-06
Abstract: PURPOSE:To obtain an image with no color difference signal even if the image with considerably less vertical correlation is image-pick up by controlling the gain of a gain control circuit by means of the difference signal of the one horizontal period delay signal and the non-delay signal of a non-modulation signal component among a space modulation signal component. CONSTITUTION:A first gain control circuit 13 is provided in a signal path by a second horizontal period delay circuit IHDL12. With adding and subtracting separated R signal and B signal with a modulation color signal which is not delayed by one horizontal period, a color difference matrix circuit 16 takes out two color difference signals, namely, (R-Y) signal and (B-Y) signal, and a second control circuit 18 controls the gain of the (R-Y) signal. For removing the color difference signal which occurs when there is no vertical correlation or when it is considerably less, the second gain control circuit 18 operates when the required gain exceeds a limited gain control range in the first gain control circuit 13.

Title: Semiconductor non-volatile memory
Inventor: ARASE KENSHIROU
IPC: G11C17/00
Filed: 1994-02-24
Abstract: PURPOSE:To write all bits in parallel by drawing charge of a charge storage layer, changing a threshold value to an intermediate level between a threshold value of a non-writing state and a target threshold value, and then changing the threshold value from the intermediate level to the object value. CONSTITUTION:-8v is for example, applied to word lines WL1-WL8 by a writing operation of a first step, and a voltage 6V is applied to a bit line BL. Then, electrons in a floating gate (FG) are drawn from a drain, and a threshold voltage is lowered from 5V to an intermediate level of about 3V. Subsequently, a higher word line voltage such as -10V is set by a writing operation of a second step, and a bit line BL voltage of 6V is applied as it is. Then, the electrons in the gate FG are further drawn from the drain, and a threshold voltage is lowered from the 3V to a desired level 1-2V. Thus, after the writing operation of the first step is executed for 1msec, the writing operation of the second step is subsequently conducted for 1msec.

Title: Tuning indication circuit
Inventor: KUREBAYASHI SHINPEI
IPC: H03J3/14
Filed: 1979-03-07
Abstract: PURPOSE:To make it possible to display a tuning point and out-of-tune direction by letting a fixed circuit decide on whether a reception frequency is out of tune in a positive or genative direction. CONSTITUTION:When a reception frequency gets out of tune, a positive or negative voltage is developed between two output terminals 1 and 2 of FMIF and detection circuit A nearly in proportion to the shift in frequency. This voltage and inverted voltage are applied to DC amplifiers B1 and B2. Next, a voltage between output terminals 4 and 5 of those amplifiers is applied to detuning decision circuit C, which makes a decision on its voltage value and polarity. As a result of the decision of circuit C, when the polarity is positive, higher-frequency-shift display unit D1 is put into operation and when negative, lower-frequency-shift display unit D2 comes on. Futher, when there is no shift in frequency, it is displayed by tuning display unit F via tuning decision circuit E. Thus, the tuning point and positive or negative out-of-tune direction can be displayed.

Filed: 1992-02-14
Abstract: PURPOSE:To obtain the information processor which can improve the reliability of an entire system by acculately judging the transfer error of status when transferring the status through a bus connector by an input/output controller. CONSTITUTION:When transferring the status to a main storage device 3, first of all, an input/output controller 6 transfers the status to a bus connector 4. When the status is normally received, the bus connector 4 reports the normal end of transfer to the input/output controller 6 and holds the ID number of the input/output controllers 6, which transfers the status, in an input/output information holding part 14. Next, the bus connector 4 transfers the status to the main storage device 3. When transfer error is generated, the bus connector 4 sets data expressing the generation of transfer error to the input/output controller information holding part 41 together with the ID number. Thus, the transfer error of the status can be exactly informed of an operation processor 2.
