Patent JP-H03239869-A (JP)
Title: Vacuum chamber
Inventor: MUKAI YASUNARI
IPC: F16J12/00
Filed: 1990-02-13
Abstract: PURPOSE:To attain an ultra-high vacuum within a short time by forming a hydrogen storage alloy layer on the inner side of a vacuum chamber made of stainless steel having a strength to hold the form to constitute a wall. CONSTITUTION:When a wall 11 is heated by a heater 14, the hydrogen in a stainless steel 12 is released, and a hydrogen storage alloy 13 coat applied onto the wall 11 inner surface does not store hydrogen as it is laid in high temperature state, so that the hydrogen is stored in the air in a vessel 10. After an auxiliary exhaust device is driven to reach the vessel 10 to a determined degree of vacuum, the heater 14 is stopped, and the vessel 10 is cooled to an ordinary temperature. In this state, a part of the hydrogen is stored by the hydrogen storage alloy, but the most part is exhausted together with the air. When the auxiliary exhaust device is stopped after attainment of a higher degree of vacuum, and a main exhaust device is driven to make a ultrahigh vacuum state, the hydrogen released into the vessel 10 at the time of heating of the stainless steel 12 is stored by the hydrogen storage alloy 13 and hardly released to the inner part of the vessel 10. Thus, an ultra-high vacuum state can be attained at a low temperature and within a short time.

Title: High-frequency vibration spray nozzle for thin-film manufacturing apparatus
Inventor: MORIYA TETSUO
IPC: C23C14/24
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent a nozzle port from clogging or a thin-film thickness from being spotted by providing a needle valve body conducting high-frequency vibration in the axial direction of the nozzle port at the vicinity of the inside of the nozzle port being provided with a minute opening spraying fluid for thin-film forming in minute droplets introduced into the inside of the nozzle via a liquid-communicating conduit into an inside of a vacuum device. SOLUTION: A position of a needle valve body 50 is coarsely controlled by manually rotating a micrometer 62 of a coarse control mechanism and then the needle valve body 50 is finely controlled to a specified position to a nozzle port 46 by applying a direct current bias voltage of a fine-control mechanism to a vibrating body 56 to elongate the vibrating body 56. High-frequency voltage is superimposed on the d.c. bias voltage and under the condition wherein the needle valve body 50 is finely vibrated up and down coaxially to the nozzle port 46 by the frequency, fluid A for thin-film forming from a storage tank is allowed to be turbulent flow at a pressure not less than an atmospheric pressure via a fluid passage 78 and a gap passage between a shaft 44 and a rod 52 and ejected from the nozzle port 46 in fine particles.  As a result, clogging of the nozzle port is eliminated and particle sizes in ejected fluid are considerably reduced by allowing possibly entering dust particles to be discharged.

Filed: 1981-03-11
Abstract: PURPOSE: To avoid influences on positional relation between a supply port and an endless chain frame structure even when positional relation between the rotor and above-mentioned structure is changed to change dehydration rate by making an eccentric piece rotable against the base.  
     CONSTITUTION: When an object to be treated is fed from a supply port 28 to a dehydration chamber consisting of a rotor 2, vanes 31, a side board 32 and a filter cloth 18, liquid component is discharged through the filter cloth 18 and a groove and a hole provided on the plate 6 of an endless chain frome structure 4, and solid component remaining in the dehydration chamber is discharged from an outlet port 29.

Title: Peak detection circuit for magnetic disk device
Inventor: YAMASHITA MITSUNORI
IPC: G11B5/09
Filed: 1990-02-14
Abstract: PURPOSE:To prevent the deterioration of the operation margin of a data reproduction system by supervising a time difference between the pulse signal of a positive polarity and the pulse signal of a negative polarity, and changing the delay time of the pulse signal of either the positive or negative polarity in correspondence with the time difference. CONSTITUTION:An error detector 10 outputs an error signal H corresponding to the time difference (T1-T2) or (T1'-T2') between a delay signal G being the output of a delay circuit 7 and a delay signal F being the output of a delay circuit 8. Then, a control signal I obtained by smoothing the error signal H being the output of the error detector 10 in a filter 11 and setting it to an almost DC signal is obtained. The delay circuit 8 changes the delay time by the control signal I from the filter 11. Namely, the delay time is set to be equal to the delay time of the first delay circuit 7 when the control signal I is '0'. When the control signal is the positive polarity, it is set to the value larger than the delay time of the first delay circuit 7, and to the value smaller than the delay time of the first delay circuit 7 when it is the negative polarity. Thus, the deterioration of the operation margin in the data reproduction system owing to the distortion of a reproduced waveform and the shift of a timing generated in a peak detection circuit can be prevented.

Filed: 1984-02-22
Abstract: PURPOSE:To access a desired position of information, which is recorded on a tape, in a high speed by recording one index information on several frames to shorten the frame length and recording repeatedly all index information. CONSTITUTION:In case the first information unit is switched to the next unit after recording of the first information unit is terminated, the information unit number is incremented when a number button 18 is depressed. Each information unit number and the time code of the start position are stored in order in an index information recording device 13. At a recording time, index information are not recorded simultaneously because the total number of information units recorded on the tape and the time code of each information unit are not known. Consequently, an index button 19 is depressed when recording of all information units is completed, and index information in the device 13 are distributed to individual frames and are recorded repeatedly.

Filed: 1983-03-04
Abstract: PURPOSE:To reduce ground fogging of a recording material and markedly reduce fogging generated during preservation and a lowering of a color development performance with time, by using a specified spiro compound excellent as a coloring matter precursor. CONSTITUTION:A spiro compound of formula I is used in a recording material which provides a colored body on contact with an acid. The spiro compound can be synthesized by a method wherein a compound of formula II is treated with a chlorinating reagent such as phosphorus pentachloride, phosphorus oxychloride or thionyl chloride, and the resultant compound is brought into reaction with a bezoic acid having an amine residue at the meta-position or a derivative thereof. The spiro compound is a colorless or light-colored crystal, has a high solubility to organic solvents, and speedily develops a color when being brought into contact with an electron-acceptive substance. Thus developed coloring matter is extremely stable as compared with a coloring matter formed from a color former, and it hardly undergoes discoloration or decoloration even when being irradiated with light for a long period of time or being subjected to heat or moisture. In the formulas, each of R1 and R2 is H, halogen, alkyl, alkoxy, nitro or the like, R3 is an amine residue, and Y is a group required for forming a 6-membered ring consisting of non-metallic atoms.
