Title: Signal recording and/or reproducing device, signal recording and/or reproducing method and recording medium
Inventor: SATO TSUGUO
IPC: G11B5/008
Filed: 1995-07-05
Abstract: PURPOSE: To correctly detect a tracking error signal by obtaining a correct tracking servo signal. CONSTITUTION: A pilot signal from a recording amplifier 3 obtained by frequency-dividing a system clock with a frequency divider 2 is recorded on a recording medium in the timing of a timing signal GP1 and thereafter, the pilot signal is reproduced by a recording/reproducing head 22 and delayed in a delay circuit 4 and a servo signal whose signal is shifted by a phase shifter 5 is recorded in the timing of a timing signal GP2 . Then, the pilot signal and the tracking servo signal are reproduced by the recording/reproducing head 22 and delayed in the delay circuit 4 and then an XOR between the reproduced tracking servo signal and the delayed pilot signal is obtained in an XOR circuit 11 to be subjected to a sample-hold in a sampling hold circuit 13 and then a servo error signal is obtained.

Inventor: ISHIZUKA HIROSHI
IPC: B24B37/00
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To provide fine single crystal type abrasive material particles which simultaneously meet the requirements for the slurry processing abrasive grains, while using the diamond synthesized under a static ultra-high pressure, that (1) a large amount can be processed per unit time, (2) the roughness of processed surface is small, and (3) the number of abrasive grains which are jamed into the processed surface and remain there is small when the material to be processed is of a soft material, and a method for producing the same. SOLUTION: Diamond abrasive material particles have a thermally affected structure due to a heat treatment at a temperature of not lower than 1,000 deg.C and are a non- aggregate agglomeration of fine single crystal particles of diamond having an average particle diameter (D 50 value) of not greater than 5 μm, and the surfaces of the diamond particles are covered with non-diamond carbons at a mass ratio of at least 0.5% based on the entire diamond particles. A method for producing modified diamond abrasive material particles comprises heating diamond particles having an average particle size (D 50 value) of not smaller than 5 nm at a treating temperature of not lower than 1,000 deg.C in a non-oxidative atmosphere or in vacuo, thereby converting a part of the surface of the diamond particles to non-diamond carbon structure.

Title: Device and method for retrieving information
Inventor: IKEDA YUJI
IPC: G06F12/00
Filed: 1995-06-13
Abstract: PURPOSE: To provide an information retrieving device and method which are capable of efficiently performing data processings in accordance with data storage capacity and the data processing work of a user. CONSTITUTION: When a data preservation processing in which data for which a filtering is performed is preserved in preservation data 200 is performed in an information retrieving system, the preservation storage capacity of the data preserved in the preservation data 200 is measured. Based on the measured result, the level of the filtering to be performed in a data filtering part 302 is decided. For instance, in the case of the storage capacity of 0 to 100 K byte, the level is defined as 100 byte per matter, in the case of the 100 K byte to 1 M byte, 500 byte per matter is defined, in the case of 1 M byte to 5 M byte, 1 K byte per matter is defined, and in the case of 5 M byte, the non-existence of the filtering is defined. Thus, the value reducing data by increasing the filtering as storage capacity is reduced is defined as a filtering level.  In the example of a newspaper article, the data for which the filtering is performed receives a data compression and becomes the size. When the filtering level becomes high, the data becomes the size of only the title of the article. Thus, the data preservation according to the using size of storage capacity can be performed.

Filed: 1987-07-08
Abstract: PURPOSE:To prevent a streamer phenomenon due to a gas leak via simple constitution by positioning an electric field relaxation ring in such a way as to surround a connection part between a gas introduction pipe and a connection pipe. CONSTITUTION:An electric field relaxation ring 12 is so arranged as to surround a connection part between a connection pipe 7 and a gas introduction pipe B, or an engagement part between a projection part 11a and the receiver groove 11b thereof. The electric field relaxation ring 12 is electrically in contact with a presser screw 10 and kept at the same potential as said presser screw 10 and connection pipe 7, or a pullout electrode 5. According to the aforesaid construction, a space exposed to a helium gas leak comes to have the same potential as a connection member via the ring 12.

IPC: H01J37/28
Filed: 1987-07-10
Abstract: PURPOSE:To prevent the damage of a sample and a probe due to their collision and to bring them close to each other in a short time, by moving a rough motion mechanism until a tunnel current is detected when the sample is brought close to the probe. CONSTITUTION:Simultaneously when a voltage is impressed between a sample 11 and a probe 10 by a current detector 12, a voltage is impressed on a Z-axis piezoelectric element 6 by the working of a feedback function of a Z-axis control circuit 6 so as to make a certain set current flow between the probe 10 and the sample 11, and thereby the probe 10 is brought close to the sample 11. A rough motion mechanism and the probe 10 supported thereby are stopped by the start of a servo circuit 2 when the current flowing between the sample 11 and the probe 10 is detected. After the fixation by a fixing mechanism 4 is released, the servo circuit 2 is turned OFF. Thereby the rough motion mechanism is made to stand still, and an image of the sample is obtained by the working of a scanning mechanism 8, the Z-axis control circuit 6, etc.

Title: Color cathode-ray tube
Inventor: YOKOYAMA SHOICHI
IPC: H01J29/02
Filed: 1990-06-28
Abstract: PURPOSE:To support a shadow mask inside a panel with good reproducibility by forming an oxygen film over the whole surface of a stud pin, and forming a carbon film on the oxygen film of the stud pin detention part on which a fit hole in a resilient support is fitted and detained therewith. CONSTITUTION:A carbon film 38 is formed over an oxygen film 37 of that part of a stud pin 32 where a fit hole in a resilient support 33 is fitted and detained. This carbon film 38 fills an evenness of the oxygen film 37 on the surface of the fit part to flatten the surface, and also excellent lubrication inherent in the carbon film 38 lessens the friction resistance which might act when the resilient support 33 is fitted on the stud pin 32. Thereby the resilient support 33 can be fitted and detained on/with the stud pin 32 always in the same position relationship, so that a high precision reproducibility is obtained. This precludes dislocation of a shadow mask, which is mounted and removed in reversals under the color CRT manufacturing processes, and the shadow mask can be mounted in the same position at all times.

Abstract: PURPOSE:To feed paper manually without using paper feed means for exclusive use by mounting a manually feeding cassette into an insertion port for automatic feeding cassette. CONSTITUTION:The base plate 37 of an automatic feeding cassette 32 is lifted by a press contact roll 15, and the uppermost sheet of copying paper 42 contacts with a feed roll 1.
